The lock is hard to unlock and loosenIf the lock is difficult to turn and loose, it may be due to the following reasons and solutions:
1. ** Screw loosened **
- [Reason: The vibration in daily use may loosen the screw on the door lock, causing the anti-lock function to be affected and the door lock to be loose.]
- The solution was to use a suitable screw driver (such as a cross screw driver, depending on the type of screw) to tighten the screw on the door lock. If it was an indoor door lock, there were usually two fixing screws inside the door. After loosening them, the front and rear door locks could be separated. After tightening the screws, they could be reinstalled.
2. ** Worn or damaged internal parts **
- Reason: Long-term use will cause the internal components of the door lock, such as the lock core, lock tongue, spring, etc., to be worn or damaged, causing the lock to be difficult to twist and loosen.
- Solution: Check if the door lock components are worn or damaged. If there are, replace them with new parts. For example, if there was a problem with the rebound spring and there was no strength to rebound, he could buy a suitable spring to replace it. If the gears were worn out, the old gears could be replaced with new ones.
3. ** Lacking grease **
- [Cause: The interior of the door lock is lacking in grease, and the friction between the parts increases, affecting the locking operation and possibly causing a sense of loosening.]
- [Solution: You can use some lubricant, such as Deli rust removal and anti-rust lubricant, etc., to make the door lock operate more smoothly.]
4. ** Lock Core Malfunction **
- [Reason: The lock core may wear out after a long period of use, affecting the anti-lock function and causing it to become loose.]
- Solution: If the ordinary door lock has been used for five or six years, consider replacing the lock core to restore its normal function.

What causes the contraction membrane to loosen?The phenomenon of the shrink film loosening could be caused by the following reasons:
1. ** Machine factor **: If it is PE shrink film, the shrink machine will pack it tightly at the beginning of the operation, but it will become loose after a few days. This situation may have nothing to do with the machine. However, if the packaging is not evenly heated during the heat shrinking process, it may also cause reverse loosening. In addition, there may be a situation in the furnace chamber of the shrinking machine where the middle group of heating tubes is burned (or the power is reduced), resulting in poor shrinking effect and anti-loosening. There may be some errors in using an infrared thermometer to check the temperature in the furnace. A clamp-on ammeter should be used to check the current of each group of heating tubes to see if it is normal. Also, the packaging is very loose, which may be due to insufficient cooling time.
2. ** Film's own characteristics **: The shrinking force of the film will weaken, and the thinner the film is, the easier it is to reverse loosen.
3. ** Item packaging factor **: If PE shrink film is used to package soda bottles, the air pressure in the bottle during packaging may affect the shrinking effect, resulting in reverse loosening. This requires the temperature and pressure of the shrinking machine to be adjusted according to the actual situation.

What are the names of the drugs that loosen skeletal muscles?Medicines that loosened skeletal muscle were also known as skeletal muscle relaxants, or muscle relaxants for short. They were mainly divided into two types: depolar and non-depolar.
Depolar muscle relaxants were commonly used, such as Succinylchlor. This type of drug bound to the N2 receptor on the endplate membrane of the motor nerve, causing the muscle cell membrane to produce a long-lasting depolar effect. The response to the acylethylchlor was weakened or disappeared, resulting in skeletal muscle relaxation.
Non-depolar muscle relaxants were also known as competitive muscle relaxants. They could compete with the N2 receptor on the endplate membrane of skeletal muscle with the N2 receptor. They had no intrinsic activity, but by blocking the binding of the N2 receptor to the N2 receptor, the endplate membrane could not be depolar, resulting in skeletal muscle relaxation. Commonly used were tubocurarine, caprylinium, docurinium, micurinium, pancurinium, and vecurinium.
Since muscle relaxants have a strong effect on skeletal muscles, please take them under the doctor's guidance to avoid accidents.

Sunflowers loosen the soil? How to maintain them?There was no clear mention of sunflower loosening soil in the information provided. Sunflower maintenance methods are as follows:
- ** Soil **: The requirements for the soil are not high, but it is best to use soil with good drainage and humus. Some base fertilizers can be applied, and the soil's pH value should be maintained between 6.0 and 7.5.
- Illumination: During the growth and flowering process, you must receive light. It is best to cultivate in a sunny place. Potted plants can be moved outdoors to bask in the sun.
- ** Temperature-wise: The temperature should be around 21 - 27 ° C during the day and around 10 - 16 ° C at night. The temperature difference should not be too small, or the stems and leaves might grow excessively, and it would not be cold resistant.
- ** Water content **:"Don't be short of water for a long time. You can water it once every 1 - 2 days during the growth period. When the temperature is high, you can water it more. If it's a potted seedling growing period, you have to water it thoroughly once the soil is dry. When it grows strong in the later stage, you have to water it thoroughly every time. If you buy sunflowers online, there are different ways to wake up flowers according to the state of the leaves. Before waking up flowers, you have to peel off the big leaves and leave only the small leaves. According to the height of the bucket, cut the stems diagonally at 45 degrees and put them into the flower awakening bucket to wake up flowers. After waking up flowers, insert them into a vase. Add 1/3 of the water in the vase. The water cannot be broken. Add 1/2 of the preservation agent or two drops of 84.(Because 84 has a corrosive effect, do not drip too much), the flower branch needs to be cut at a 45-degree angle and then cut a 2-centimeter cross cut, and the part of the flower branch exposed to the vase needs to be a little longer.
- ** Reproduction **: Sowing is the most suitable method for reproduction. The most suitable time is from March to April in spring. The best temperature is 18 - 25 ° C. Buy plump seeds before sowing, soak them in warm water, and then sow them. Sow the tip of the seeds into the soil and cover them with a layer of soil.
- * *
- "In terms of fertilizers, there is no need to frequently apply fertilizers. If the soil is particularly poor and you want to bloom better, you can occasionally add organic fertilizer. You must avoid fertilizers with too much nitrogen, otherwise it will delay the flowering period.
- Pest and disease control: Potted sunflowers are rarely infected with pests and diseases, but if the environment is too humid, poor ventilation, or insufficient light, they may be infected with fungi such as mold and rust disease. At this time, the sick leaves should be cut off in time and sprayed with disinfectant. Potted sunflowers should be avoided in cool and humid places. In warm seasons, avoid excessive air humidity, and avoid watering the leaves and flowers so that the leaves are often wet.
