The surface of the support base 301 is threaded with a fixing bolt 306, and the rear end of the fixing bolt 306 passes through the surface of the locking support plate 304 and extends to the inner rear end of the support base 301. The surface of the locking support plate 304 is equipped with a clamping module 307, and the clamping module 307 and the locking support plate 304 are a tightly connected integrated structure.

[0018] The specific operation is as follows: During use, the magnetic positioning strip 305 is magnetically connected to the inner side of the magnetic positioning groove 303 to connect the snap-fit ​​support plate 304 and the snap-fit ​​fixing groove 302, which plays an auxiliary positioning role. Press down the snap-fit ​​support plate 304 so that the lower end of the snap-fit ​​support plate 304 is snapped into the inner side of the snap-fit ​​fixing groove 302. At the same time, the magnetic positioning strip 305 is snapped into the magnetic positioning groove 303 to further fix the snap-fit ​​support plate 304. The fixing bolt 306 further strengthens the connection between the support base 301 and the snap-fit ​​support plate 304, so as to facilitate the stable installation of the clamping module 307. Disassembly is convenient, and clamping modules 307 of different specifications and sizes, such as V-shaped clamping module 307, round hole clamping module 307, or square hole clamping module 307, can be easily replaced.

[0019] Please refer to Figures 3 to 4The support base 1 has a clamping assembly 4 for auxiliary clamping on its surface. The clamping assembly 4 includes a limiting slide groove 401, a left vertical plate 402, a right vertical plate 403, a servo motor 404, and a bidirectional threaded screw 405. The limiting slide groove 401 is formed on the upper part of the front and rear surfaces of the support base 1. The left vertical plate 402 is installed on the left side of the support base 1, and the right vertical plate 403 is provided on the right side of the support base 1.

Anti-slip pads 6 improve the tightness and stability of the installation. The magnetic positioning strip 305 connects magnetically to the inner side of the magnetic positioning groove 303, assisting in the positioning of the snap-fit ​​support plate 304 to the snap-fit ​​fixing groove 302. Pressing down on the snap-fit ​​support plate 304 causes its lower end to engage with the inner side of the snap-fit ​​fixing groove 302. Simultaneously, the magnetic positioning strip 305 engages with the magnetic positioning groove 303, further securing the snap-fit ​​support plate 304. Fixing bolts 306 further reinforce the connection between the support base 301 and the snap-fit ​​support plate 304, facilitating the... The clamping module 307 is stably installed and easy to disassemble. It can be easily replaced with clamping modules 307 of different specifications and sizes, such as V-shaped clamping module 307, round hole clamping module 307, or square hole clamping module 307. The servo motor 404 is started, which drives the bidirectional threaded screw 405 to rotate along the surface of the left vertical plate 402 and the right vertical plate 403. This drives the two sets of internal threaded movable cylinders 406 to move in opposite directions at the same time. The internal threaded movable cylinders 406 drive the movable support plate 2 to move, which in turn drives the clamping modules 307 to move in opposite directions at the same time, thereby clamping the workpiece. The sliding connection between the limiting member 407 and the inner side of the limiting slide groove 401 limits the movement of the movable support plate 2.
