Then, the lock core can be inserted into it reversely, and finally, the lock core and the drawer end plate are connected and fixed by screws. When drilling a hole along the upper edge of the traditional drawer end plate, a drill bit is directly used. Due to the lack of axial auxiliary positioning, the drilled hole groove will have an axis offset, resulting in the inclination of the installed lock core and poor overall effect. Accordingly, the utility model provides a processing device for the keyhole grooves of a lock core. Content of the Utility Model

The movable plate is slidably connected to the fixed plate, and the movable plate moves forward and backward relative to the fixed plate. The front end of the fixed plate is provided with a front clamping plate and a rear clamping plate extending downward. A clamping groove is formed between the rear clamping plate and the front clamping plate. The rear end of the movable plate is provided with a guide plate extending downward. A guide hole is opened on the guide plate. It also includes an avoidance hole coaxially arranged with the guide hole, and the avoidance hole is opened on the front clamping plate and the rear clamping plate. A limiting hole extending forward and backward is opened on the fixed plate, and a movable limiting block arranged on the movable plate is slidably connected in the limiting hole. A fixed limiting block arranged on the fixed plate is provided at the rear side of the movable limiting block, and a tension spring is connected between the fixed limiting block and the movable limiting block.

[0005] The utility model is further arranged as follows: A linear guide rail extending forward and backward is arranged on the fixed plate, and a linear slider is slidably connected to the linear guide rail. The movable plate is arranged on the linear slider.

[0006] The utility model is further arranged as follows: A positioning cone is connected to the guide plate at the front side of the guide hole, and the positioning cone is coaxially arranged with the guide hole.

[0007] The utility model is further arranged as follows: A locking screw with an end extending into the clamping groove is threadedly connected to the rear clamping plate.

[0008] The utility model is further arranged as follows: The locking screw is a hand-tightening locking screw.

[0009] In summary, the utility model has the following beneficial effects: The lock core hole groove processing device involved in the utility model first places the drawer end plate to be drilled in the clamping groove and fixes it with the locking screw, so that the drawer end plate is fixed to the device. Then, the non-rotating part at the front end of the drill bit is inserted into the guide hole and moved forward, causing the drill tip that moves forward and rotates at high speed to move in a direction perpendicular to the drawer end plate, drilling a lock core hole groove with an axis that does not deviate. It has high processing accuracy, is easy to use, has a complete overall function, and strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS
