[0023] See also Figure 1-Figure 4 The utility model provides a technical solution: a prosthetic hand with a grip strengthening effect, the prosthetic hand with a grip strengthening effect comprises: a prosthetic thumb 1, a support plate 2 is arranged at one end of the prosthetic thumb 1, a lifting rod 3 is inserted into the support plate 2, a clamping plate 4 is arranged at one end of the lifting rod 3, a placement groove 5 is opened at one end of the prosthetic thumb 1; a small electric push rod 6, a bottom plate 7 is arranged at one end of the small electric push rod 6, a limit plate 8 is arranged on the surface of the bottom plate 7, and an anti-slip strip 9 is arranged on the surface of the clamping plate 4;
[0024] When using the prosthetic thumb 1 to clamp and place heavier objects, the anti-slip strip 9 arranged on the surface of the clamping plate 4 arranged above the prosthetic thumb 1 can be used to increase the friction between the prosthetic thumb 1 and the object, and then the limiting plate 8 inserted in the clamping plate 4 can be used to further improve the grip of the prosthetic thumb 1 on the object, thereby making it easier for users to use the prosthetic thumb 1 to clamp and place heavy objects.
[0025] Embodiment 2
[0026] On the basis of the first embodiment, in order to facilitate the grasping of the object, a clamping plate 4 is provided, two groups of lifting rods 3 are provided, and the two groups of lifting rods 3 are symmetrically distributed about the placement slot 5. A spring 10 is sleeved on the surface of the lifting rod 3, one end of the spring 10 is fixedly connected to the lower surface of the clamping plate 4, and the other end of the spring 10 is fixedly connected to the surface of the support plate 2. The end face of another group of springs 10 is fixedly connected to the surface of the prosthetic thumb 1. A through hole 11 is opened on the surface of the clamping plate 4, and the anti-slip strip 9 is fixedly connected to the surface of the clamping plate 4. There are multiple groups of through holes 11, and the multiple groups of through holes 11 are regularly arranged linearly about the surface of the clamping plate 4.
[0027] When in use, the clamping plate 4 can be used in conjunction with the anti-slip strip 9 to increase the friction with the object. The setting of the spring 10 can provide a thrust to the clamping plate 4 on the one hand, and on the other hand, it is also convenient for the clamping plate 4 to automatically reset after being pressed.
[0028] Embodiment 3
[0029] On the basis of the second embodiment, in order to improve the gripping force of the prosthetic thumb 1 and the object, a limit plate 8 is provided, a small electric push rod 6 is fixedly connected to the surface of the placement groove 5, a positioning ring 12 is provided at the lifting end of the small electric push rod 6, and a limit hole is provided on the side of the positioning ring 12, a vertical plate 13 is provided at the bottom of the bottom plate 7, a positioning rod 14 is provided in the vertical plate 13, a second spring 15 is sleeved on the surface of the positioning rod 14, one end of the second spring 15 is fixedly connected to the side of the vertical plate 13, and the other end of the second spring 15 is fixedly connected to the surface of the positioning rod 14, one end of the positioning rod 14 can be inserted into the limit hole provided on the side of the positioning ring 12, a sealing plate 16 is provided in the placement groove 5, and the sealing plate 16 can seal the placement groove 5, the limit plate 8 is fixedly connected to the surface of the bottom plate 7, the limit plate 8 can move up and down in the through hole 11, and an anti-slip plate 17 is provided on the end face of the limit plate 8, and the anti-slip plate 17 is tilted and fixed at a certain angle;
