[0002] Door locks are an important part of the security of homes, offices, and business premises. Clamp-type door locks are a common door lock installation method. The lock body is installed on both sides of the door panel through a bracket that can clamp the door panel. It is easy to install and does not require holes in the door panel. Due to the variety of thickness specifications of door panels, the size of the bracket of the existing clamp-type door lock is not adjustable. In order to be suitable for door panels of different thicknesses, brackets of various sizes are often required, resulting in increased production costs. In addition, there are tolerances in the thickness of some door panels, and the existing structure is prone to unstable installation or inability to install. Utility Model Content
