The retaining portion 3121 extends less than the difference between the radii of the stopper portion 3112 and the support portion 3111, and the width of the retaining portion 3121 on both sides is less than the width of the stopper groove 3113. Specifically, the inner hole of the stopper plate 312 is configured to be a circular hole in cooperation with the stopper portion 3112. The separation prevention portion 3121 is provided on the inner side wall of the stopper plate 312 corresponding to both ends of the stopper groove 3113. In use, after the forceps handle 11 is mounted, the stopper plate 312 and the retaining portion 3121 are fitted to the stopper portion 3112 and the stopper groove 3113 to allow the stopper plate 312 to be fitted to the support portion 3111 and rotated. The stopper portion 3112 can block the disengagement prevention portion 3121 and the stopper plate 312, and prevent the stopper plate 312 from slipping off in the axial direction of the support portion 3111. Thereby limiting the clamp handle 11 between the limiting plate 312 and the top surface of the sliding block 3 and preventing the clamp handle 1 from falling off in the using process.
Referring to fig. 5, in one embodiment, the limiting plate 312 is further closely attached with a ring-shaped supporting plate 313. The inner hole of the supporting plate 313 is matched with the cross section of the limiting part 3112, the supporting plate 313 is rotatably arranged on the limiting plate 312, and the rotating axis of the relative rotation of the supporting plate 313 and the limiting plate 312 is coaxial with the inner hole of the supporting plate 313 and the inner hole of the limiting plate 312. A positioning portion 3131 is disposed on an inner sidewall of the supporting plate 313, and the positioning portion 3131 is disposed in cooperation with the limiting groove 3113. The supporting plate 313 is sleeved outside the supporting portion 3111 to limit the positioning portion 3131 in the limiting groove 3113. Specifically, the inner hole fitting stopper 3112 of the support plate 313 is provided in a circular shape. The positioning portion 3131 is fitted into the limiting groove 3113, and two ends of the positioning portion 3131 penetrate through the limiting groove 3113 and are connected to the inner sidewall of the supporting plate 313. The limiting plate 312 is tightly attached to the supporting plate 313, so that the limiting plate 312 and the supporting plate 313 have certain frictional resistance when rotating relatively, thereby preventing the limiting plate 312 and the supporting plate 313 from rotating randomly. In one embodiment, the stopper plate 312 has a plurality of circular grooves penetrating both surfaces thereof, and the circular grooves are concentrically arranged. One surface of the supporting plate 313 is provided with a pin shaft, and the pin shaft is slidably inserted into the arc-shaped groove corresponding to each arc-shaped groove and penetrates through the limiting plate 312. One end of the pin shaft penetrating through the limiting plate 312 is provided with a pressing block, and the pressing block enables the supporting plate 313 to be tightly attached to the limiting plate 312. In one embodiment, the mounting groove 3114 and the limiting groove 3113 are the same groove. The relative rotation between the supporting plate 313 and the limiting plate 312 enables the anti-dropping portion 3121 and the positioning portion 3131 to be aligned with the limiting groove 3113 at the same time, which facilitates the installation and detachment of the limiting plate 312. The supporting plate 313 and the limiting plate 312 rotate relatively to each other, so that the anti-falling portion 3121 and the positioning portion 3131 are staggered, and the friction between the supporting plate 313 and the limiting plate 312 prevents the limiting plate 312 from rotating randomly, thereby preventing the limiting plate 312 from rotating accidentally and slipping off.
