The adsorption structure 10 includes an adsorption portion 11 and an adsorption cavity 12 communicating with the adsorption portion 11, and the adsorption structure 10 is made of an elastic material. The operating assembly 20 includes a sleeve 21 and a holding structure 22 slidably disposed along an axial direction of the sleeve 21, one end of the holding structure 22 extends from the sleeve 21 to be connected with the suction structure 10, and the sleeve 21 has a first operating state moving toward the suction structure 10 and a second operating state moving toward a side away from the suction structure 10. When the sleeve 21 is in the first working state and the sleeve 21 applies a force to the adsorption structure 10, the adsorption structure 10 is in a compressed state, and the volume of the adsorption cavity 12 is reduced, so that the adsorption part 11 is in a state to be adsorbed; when the suction structure 10 provides the sleeve 21 with a force moving towards the side far away from the suction structure 10, the sleeve 21 is in the second working state, the suction structure 10 rebounds, and the volume of the suction cavity 12 increases, so that the suction part 11 is in the suction state to suck the prosthesis to be sucked.
By applying the technical scheme of the embodiment, when the prosthesis to be adsorbed needs to be clamped by the clamp, the adsorbing portion 11 is abutted against the prosthesis to be adsorbed, the sleeve 21 is operated, so that the sleeve 21 is in the first working state until the sleeve 21 is abutted against the adsorbing structure 10 and applies an acting force to the adsorbing structure 10, the adsorbing structure 10 is in the compressed state, and the volume of the adsorbing cavity 12 is reduced, so that the adsorbing portion 11 is in the state to be adsorbed. Then, the sleeve 21 is loosened, the adsorption structure 10 rebounds under the action of the self elastic force to provide the acting force for the sleeve 21 to move towards the side far away from the adsorption structure 10, so that the sleeve 21 is in the second working state, the volume of the adsorption cavity 12 of the adsorption structure 10 is increased, the adsorption part 11 is in the adsorption state, the prosthesis to be adsorbed is adsorbed, and the clamp holder is further used for adsorbing the prosthesis to be adsorbed. Wherein, because the adsorption structure 10 is made by elastic material, in the volume change process of adsorbing chamber 12, can produce great adsorption affinity in adsorbing chamber 12, and then make adsorption affinity that adsorption part 11 treated the adsorption prosthesis great, and then solved the clamping effect of holder in the prior art relatively poor, easily take place the holder and treat the problem that the adsorption prosthesis breaks away from, guarantee that the operation can normally go on.
In this embodiment, the adsorbing structure 10 is made of elastic material, which has better flexibility, and will not scratch or damage the prosthesis to be adsorbed during the process of adsorbing the prosthesis.

In this way, the above arrangement makes it easier for the user to grasp and hold the holder, and the holder can be grasped and held by the grasping handle 222.
Specifically, when the user operates the holder, the user holds the handle 222 with one hand to make the connecting portion 223 drive the suction portion 11 to abut against the prosthesis to be sucked, and the other hand operates the sleeve 21 to make the sleeve 21 move toward the suction structure 10, and then the stopper 212 of the sleeve 21 abuts against the suction structure 10 and compresses the suction structure 10. Thereafter, the sleeve 21 is released to enable the suction structure 10 to rebound, thereby enabling the suction portion 11 to suck the prosthesis to be sucked. In the above process, the user always holds the handle 222 by his or her hand to ensure that the suction portion 11 is always abutted against the prosthesis to be sucked, and also to prevent the gripper from tilting relative to the prosthesis to be sucked to affect the gripping effect of the gripper.

In this way, when the suction structure 10 is compressed by the sleeve 21, the deformation body 13 can be retracted in its height direction, so that the volume of the suction chamber 12 is reduced. When the adsorption structure 10 is to rebound, the deformation main body 13 can rebound along the height direction, so that the volume of the adsorption cavity 12 is increased, and then negative pressure is formed in the adsorption cavity 12, and the adsorption structure 10 can absorb the prosthesis to be adsorbed through the adsorption part 11. Meanwhile, the structure is simple, easy to process and realize, and the processing cost of the clamp holder is reduced.

As shown in fig. 7, the deformation body 13 has a through hole 131 into which the rod 221 is inserted, and the holder further includes a sealing member. Wherein, the sealing member is disposed between the through hole 131 and the rod body 221 to seal the connection of the rod body 221 and the deformation body 13. Like this, in the sliding process of the adsorption structure 10 along the rod 221, the sealing member can prevent the gas outside the adsorption cavity 12 from entering the adsorption cavity 12 through the through hole 131, or reduce the gas amount entering the adsorption cavity 12, so as to ensure that the adsorption cavity 12 is in a negative pressure state, so that the adsorption structure 10 can absorb the prosthesis to be adsorbed, and further ensure that the holder can absorb the prosthesis to be adsorbed.
As shown in fig. 8, 9 and 12 to 14, the connection portion 223 is a first arc-shaped plate structure, and the arc center of the first arc-shaped plate structure is located at a side of the first arc-shaped plate structure facing the adsorption portion 11.

Meanwhile, the structure is simple and easy to process.
The structure of the connection portion 223 is not limited to this. In other embodiments not shown in the drawings, the connection portion includes a plurality of second arc-shaped plate-like structures disposed around the rod body, and an arc center of each of the second arc-shaped plate-like structures is located at a side of the second arc-shaped plate-like structures facing the suction portion.

In this way, the above-described arrangement of the slide groove 211 can prevent the handle 222 from interfering with the sleeve 21 in a structure during the user's operation of the sleeve 21 in its axial direction.
As shown in fig. 4, 8, 10 and 11, when the adsorption structure 10 abuts against the sleeve 21, a first predetermined distance is provided between the surface of the handle 222 facing the first groove wall 211a of the sliding slot 211 and the first groove wall 211a, and a second predetermined distance is provided between the surface of the handle 222 facing the second groove wall 211b of the sliding slot 211 and the second groove wall 211 b. The first groove wall 211a is located at a side of the second groove wall 211b away from the adsorption structure 10, and the first groove wall 211a is opposite to the second groove wall 211 b. In this way, during the axial movement of the sleeve 21 operated by the user, the above arrangement can prevent the handle 222 from interfering with the first groove wall 211a and the second groove wall 211b of the chute 211 to affect the normal movement of the sleeve 21, so as to improve the operational reliability of the gripper.
