As shown in fig. 1, in the present embodiment, the clamp assembly further includes an elastic member 40, wherein a first end of the elastic member 40 is connected to the mandrel 30, and a second end of the elastic member 40 is connected to a side of the guard structure 20 facing the mandrel 30, so that the guard structure 20 is covered onto the clamp body 10 under the pulling action of the elastic member 40 when the mandrel 30 is installed into the clamp body 10.
Specifically, the first end of the elastic member 40 is connected with the mandrel 30, and the second end of the elastic member 40 is connected with the protection structure 20, so that the protection structure 20 is connected to the clamp body 10 by using the elastic action of the elastic member 40, and then the protection structure 20 is covered at the open end of the clamp body 10, so that chips are prevented from entering the cavity of the clamp body 10 from the open end, the cleaning in the cavity is ensured, and the secondary use of the clamp body 10 is not affected.
As shown in fig. 1, in the present embodiment, the clamp body 10 has a clamping hole extending in the extending direction of the clamp body 10, and at least part of the inner wall surface of the clamping hole encloses a cavity.
