If it can't rebound, we can try to turn the handles on both sides to see if the handle is pressed down normally. If the pressure is normal, but the lock tongue does not rebound, there is a problem with the lock body, and a new door lock needs to be replaced directly.

1. PVC floor drain The price of PVC floor drains is relatively low, and the effect is also good. But it also has the disadvantage that the material is brittle and easy to age.
