The fixed plate 35 drives the clamping plate 34 to clamp and fix the four ends of the workpiece, making it convenient for the drill bit of the drilling machine to drill the workpiece later.

[0044] During actual operation, when this device is used, when a CNC drilling machine is drilling a workpiece, the first step is to move the support plate 218 to drive the first T-block 2103 to slide in the first T-slot 211 until the clamping plate 34 contacts one end of the workpiece. When the dual-axis motor 31 is started, the threaded rods 36 at both ends are driven to rotate, and the front and rear moving blocks 33 move toward opposite sides on the surfaces of the front and rear threaded rods 36. When the moving block 33 moves, it can drive the fixed plate 35 to move.
