The base plate is a rectangular metal plate with multiple screw holes at the top and adjusting parts installed at both ends. By adjusting the left and right pressure plates, the clamping position of the parts can be adjusted more quickly. The longitudinal position of the pad can be quickly adjusted by the adjusting parts, and the pad can slide left and right to adjust its lateral position, making the adjustment of the pad faster.

[0004] The aforementioned device consists of left and right pressure plates, which are independently adjustable, resulting in time-consuming adjustments and complex operation. Therefore, we propose a quick clamping tool for precision parts to solve the problems mentioned above. Utility Model Content

Compared with the comparative document, the operation steps are reduced. The two pressure plates can be moved at the same time by simply rotating the gear, thereby reducing the operation steps and improving the installation efficiency.

[0017] (2) The pressure plate is driven to move up and down by setting a screw. The screw is connected to the threaded hole on the surface of the pressure plate. Turning the first handle drives the screw to rotate, causing the pressure plate to move down or up. The pressure plate is pressed down to lock and fix the precision parts. A limit rod is set on one side of the pressure plate. The limit rod is inserted into the inside of the side frame. The limit rod is used to limit the pressure plate and prevent the pressure plate from rotating when the screw is turned. Attached Figure Description
