[0014] Further, the rotating column is rotatably connected with the inside of the mounting seat, the gear is fixedly connected with one end of the rotating column, and the gear is engaged with the first rack and the second rack.

[0015] By the above scheme, in use, rotating the rotating column will drive the gear to rotate, thus driving the first rack and the second rack to move in opposite directions.

[0016] Further, the threaded rod is fixedly connected with the end of the rotating column away from the gear, and the second nut is threadedly connected with the surface of the threaded rod.

[0017] By the above scheme, in use, rotating the second nut makes the second nut contact the surface of the mounting seat, at this time the threaded rod is locked.

[0018] Compared with the prior art, the technical scheme of the application has the following beneficial effects:

[0019] The pre-assembly device for the intelligent lock, in use, first rotates the rotating knob with respect to the length of the door lock. The rotating knob rotates to drive the threaded column to rotate, thereby driving the second base to move. When the length of the entire device matches the specification of the door lock, the threaded rod is rotated. The threaded rod rotates to drive the rotating column and the gear to rotate, thereby causing the first rack and the second rack to move in opposite directions, thereby driving the first clamping block and the second clamping block to move. When the distance between the first clamping block and the second clamping block is the same as the width of the door lock, the door lock is placed between the first clamping block and the second clamping block. At this time, the handle is between the mounting seat and the first base and the second base. In the installation process, the handle is not abraded, thereby avoiding affecting the appearance of the handle as much as possible during the assembly process. BRIEF DESCRIPTION OF DRAWINGS
