[0006] 4. The cover plate is provided with a hook which engages with the card slot.

[0007] There are certain problems with the filter handle of this structure during use. When the lock core is pulled backward to open the lock, since the slots and hooks are only provided on the left and right sides and the rear of the lock, and there are no slots and hooks in the front, the side of the bottom plate in front of the lock or the side of the cover plate in front of the lock is prone to twisting and deformation after being pulled backward. The specific manifestations are: 1. The front of the bottom plate or the cover plate is tilted upward, causing the slots and hooks on the left and right sides of the bottom plate and the cover plate to accidentally separate.

[0008] 2. The lock disintegrates, affecting the normal use of the lock.

[0009] This design defect results in insufficient reliability and durability of the lock, which is prone to failure during use, causing inconvenience to users, so it is necessary to make further improvements to it. Utility Model Content
