The thickness of the clamping block plus the rotating plate is greater than the depth of the limiting hole, so that the clamping effect of the limiting disk surface and the positioning plate surface on the hand mold disappears, thereby facilitating the rotation and disengagement of the hand mold.

[0011] Optionally, a guide surface is provided on the surface of the clamping block facing the limiting plate, and the guide surface is in the shape of an arc protrusion, and the guide surface can abut against the inner wall of the clamping groove and guide the clamping block to leave the clamping groove.

[0012] By adopting the above technical solution, when the hand mold drives the rotating plate to rotate, the guide surface abuts against the inner wall of the clamping groove and guides the clamping block to separate from the clamping groove, reducing the wear between the clamping block and the inner wall of the clamping groove, thereby extending the service life of the hand mold seat.

[0013] Optionally, the limit plate surface is provided with a plurality of guide arc grooves, and the two ends of the guide arc grooves are connected to two adjacent clamping grooves in a one-to-one correspondence, and the inner wall of the guide arc groove can abut the guide surface and guide the clamping block to be embedded in the clamping groove.

At the same time, the inner wall of the guide arc groove guides the clamping block to embed into the adjacent clamping groove, thereby reducing the wear between the clamping block and the limit plate, thereby extending the service life of the hand mold seat.

[0019] Optionally, the arc surface of the limiting disk is provided with a force application plane.

[0020] By adopting the above technical solution, a force-applying plane is provided on the arc surface of the limit plate, and the force-applying plane provides a force point for the user to hold in order to form support. The user holds the outer periphery of the hand mold with his other hand and rotates it, so that the user is not likely to slip when holding the outer periphery of the limit plate, thereby improving the convenience of the user in using the hand mold holder.

[0021] Optionally, the surface of the limiting disk is connected to a tightening ring capsule, and the inner ring of the tightening ring capsule can press against the outer periphery of the hand mold to form a limit.

[0022] By adopting the above technical solution, the tightening ring bag is connected to the surface of the limiting disk, and the inner circle of the tightening ring bag surrounds the rotating plate. When the bottom of the hand mold abuts against the surface of the limiting disk, the inner circle of the tightening ring bag presses against the outer periphery of the hand mold to form a limit, further improving the limit stability of the hand mold on the limit seat.

[0043] Reference Figure 3 and Figure 4 When the hand mold 7 needs to be removed, the hand mold 7 is driven to rotate on the surface of the limiting disk 4, driving the rotating plate 6 to rotate around the axis of the rotating shaft 2, and the guide surface 81 abuts against the inner wall of the tightening groove 41 and guides the tightening block 8 to disengage from the tightening groove 41. The surface of the tightening block 8 abuts against the surface of the limiting disk 4, and the sum of the thickness of the tightening block 8 and the rotating plate 6 is greater than the depth of the limiting hole 71, so that the tightening force of the positioning plate 5 and the surface of the limiting disk 4 on the hand mold 7 disappears, making it convenient for the user to drive the hand mold 7 to rotate and disengage from the limiting disk 4, thereby improving the convenience of the user to use the hand mold base.

The buffer surface 91 can abut the surface of the hand mold 7 and guide the bottom of the hand mold 7 to abut the surface of the limit plate 4. When the bottom of the hand mold 7 abuts the surface of the limit plate 4, a plurality of positioning strips 9 surround the outer periphery of the hand mold 7, and the surface of the positioning strips 9 abuts the surface of the hand mold 7 to form a limit, so that the hand mold 7 is not easy to deviate on the surface of the limit plate 4, thereby improving the limiting stability of the hand mold 7 on the surface of the limit plate 4.

[0046] Reference Figure 1 The limiting plate 4 includes a limiting portion 43 and a supporting portion 44. In the embodiment of the present application, the limiting portion 43 and the supporting portion 44 are both circular plates. The end of the limiting portion 43 is coaxially welded and fixed to the end surface of the supporting portion 44.

[0049] Reference Figure 2 The end face of the inflatable piston 111 protruding from the disk surface of the limiting portion 43 can abut against the bottom of the hand mold 7. When the bottom of the hand mold 7 abuts against the disk surface of the limiting portion 43, the bottom surface of the hand mold 7 abuts against the surface of the inflatable piston 111 and drives the inflatable piston 111 to slide in the direction close to the sliding chamber 45.

The sliding direction of the clamping block 8 is parallel to the axis of the rotating shaft 2. A clamping elastic member 12 is connected to the clamping block 8. The clamping elastic member 12 can be a compression spring or a tension spring. In the embodiment of the present application, the clamping elastic member 12 is a compression spring with a certain deformation ability. One end of the clamping elastic member 12 in the elastic force direction is connected to the surface of the clamping block 8, and the other end of the clamping elastic member 12 in the elastic force direction is connected to the inner wall of the clamping cavity 61.
