A silicone protrusion 241 is fixedly connected to the inner wall of 24, and a through hole 242 is provided on the top of the clamping half ring 24. The electromagnet 212 is controlled to generate magnetic force by powering on. The principle of mutual repulsion between the electromagnet 212 and the magnetic block 214 at the same level is used to cause the movable plate 22 to move relative to the reference plate 21, and at the same time, the two clamping half rings 24 are opened, and then the periosteal nail is placed on the inner side of the clamping half ring 24 and then the electromagnet 212 is closed. The initial elastic force of the elastic member 211 can clamp the periosteal nail on the inner side of the clamping half ring 24, realizing the function of automatic clamping, avoiding the problem of inconvenience of manual force clamping operation, and at the same time, the clamping half ring 24 can fit with the outer surface of the periosteal nail to improve the stability of clamping. The design of the silicone protrusion 241 can further improve the stability of clamping. The material of the clamping half ring 24 is set to an elastic alloy, such as 3J53 alloy.

[0021] As an implementation method in this embodiment, Figure 2 、 Figure 3As shown, a hollow frame 215 is fixedly installed on the front of the reference plate 21, and a sliding shaft 216 is slidably connected to the inner wall of the hollow frame 215.
