[0031] The positioning module 300 includes a plurality of tooth plates 310 enclosed on the outside of the threaded rod 250, a transmission gear 320 and a driving gear 330 movably mounted on the top of the top plate 230, a screw rod 340 connected to the bottom of the driving gear 330, an L-shaped lifting plate 350 connected to the bottom end of the screw rod 340, and a protrusion 360 connected to the top of the L-shaped lifting plate 350. The transmission gear 320 is meshed between the tooth plates 310 and the driving gear 330. The screw rod 340 is threadedly connected to the slide plate 220. The L-shaped lifting plate 350 is movably plugged into the slide plate 220.

[0032] Furthermore, a circular groove is formed on the top plate 230 , and the circular groove is vertically coaxial with the threaded rod 250 . The circular groove is provided to provide conditions for the gear plate 310 to rotate smoothly.

[0033] Furthermore, a plurality of tooth plates 310 are arranged in a ring shape at equal intervals, and the bottom ends of the tooth plates 310 are movably extended into the circular groove. With this layout design, the threaded rod 250 can smoothly rotate with the tooth plates 310 .

[0034] Furthermore, the bottom of the driving gear 330 is in contact with the top of the top plate 230 , and the top of the driving gear 330 is lower than the top of the transmission gear 320 .

[0038] The working principle and use process of the utility model are as follows: when the device is put into actual use, the cast iron casing is placed in the limit groove 120, and then the slide plate 220 is moved along the slideway 210, so that the pressure plate 260 at the bottom of the slide plate 220 comes to the flat part of the cast iron casing, and then the threaded rod 250 is rotated, and the threaded rod 250 brings the pressure plate 260 down until the pressure plate 260 is pressed against the cast iron casing. During this process, multiple tooth plates 310 rotate with the threaded rod 250, and then under mechanical transmission, the transmission gear 320 rotates, the driving gear 330 rotates, and then the screw rod 340 brings the L-shaped lifting plate 350 and the protrusion 360 to be lifted. When the protrusion 360 is interference fit with the inner wall of the slideway 210, the pressure plate 260 presses the cast iron casing, and the cast iron casing of any model and shape can be fixed to improve the clamping effect.
