The positive wire ear seat 2 and the reverse wire ear seat 9 are respectively arranged on the left and right sides of the friction component fixing platform 3. The positive wire ear seat 2 is connected with the left wedge block 4, and the reverse wire ear seat 9 is connected with the right wedge block 8. The lower wedge block 5 is provided with a guide through hole, and one end of the guide member 10 is connected with the friction component fixing platform 3, and the other end of the guide member 10 passes through the guide through hole. When the positive and negative lead screw 1 rotates, the left wedge block 4 with the positive wire ear seat 2 and the right wedge block 8 with the reverse wire ear seat 9 are simultaneously back-to-back or relatively slid, and the lower wedge block 5 moves closer to or away from the friction component fixing platform 3 along the guide member 10. It should be noted that the friction component fixing platform 3 and the lower wedge block 5 have a certain spacing distance, which is used for the lower wedge block 5 to move closer to or away from the friction component fixing platform 3.

[0018] As a preferred embodiment, the left wedge block 4 and the right wedge block 8 have the same structural shape, and the longitudinal cross-sections are both trapezoidal, and the tips are opposite. It has a simple structure and is easy to disassemble and assemble. When the positive and negative screws 1 are rotating, when the left wedge block 4 with the positive wire ear seat 2 and the right wedge block 8 with the negative wire ear seat 9 slide relative to each other at the same time, the lower wedge block 5 moves away from the friction component fixing platform 3 along the guide member 10; when the left wedge block 4 with the positive wire ear seat 2 and the right wedge block 8 with the negative wire ear seat 9 slide back to back at the same time, the lower wedge block 5 moves close to the friction component fixing platform 3 along the guide member 10.

[0019] As a preferred embodiment, the friction component fixing platform 3 is provided with a mounting through hole 12, and the forward and reverse lead screws 1 are fixedly arranged in the mounting through hole 12 through bearings. The structure is simple and the assembly and disassembly is convenient.

[0020] As a preferred embodiment, the guide member 10 is a guide pin, and the pin cap of the guide pin is arranged outside the lower wedge block 5, and the size of the pin cap is larger than the aperture of the guide through hole; when the lower wedge block 5 moves away from the friction component fixing platform 3 along the guide member 10, the pin cap plays a role of limiting and blocking on the outside. The pin rod of the guide pin passes through the guide through hole and is threadedly connected to the friction component fixing platform 3, which is convenient for disassembly, assembly and adjustment, and the pin rod is slidably connected to the guide through hole.

[0021] As a preferred embodiment, the friction mechanism body 11 is a bilaterally symmetrical structure with a simple structure and convenient assembly and disassembly.

[0022] As a preferred embodiment, there are two friction mechanism bodies 11, and the friction blocks 6 of the two friction mechanism bodies 11 are arranged at a relative interval. The two friction mechanism bodies 11 work together to effectively clamp the clamped molded body, thereby improving the clamping quality and work efficiency. As a further preferred embodiment, the slideway rolling component shaft 7 is connected to the outer edge of the friction component fixing frame, and the two ends of the slideway rolling component shaft 7 are connected to the bearing, which is connected to the external circumferential circular slideway in a rolling manner, so that the two friction mechanism bodies 11 can clamp the molded body in cooperation with each other, and the molded body rotates along the circumferential circular slideway.

[0023] As a preferred embodiment, the bottom surface of the lower wedge block 5 is detachably connected to the friction block 6, for example, by means of threaded connection, which is convenient for disassembly and assembly, and a corresponding friction block 6 can be installed according to the different shapes of the clamped molded body.

[0024] The working principle of the present invention is to place the clamped formed body in the clamp, and when the pressure / friction force applied by the friction block 6 on the clamped formed body is greater than the bearing capacity of the clamped formed body, or exceeds the process requirements, the positive and negative screws 1 are rotated, and the left wedge block 4 with the positive wire ear seat 2 and the right wedge block 8 with the reverse wire ear seat 9 slide back to back at the same time, and the lower wedge block 5 moves along the guide pin in the direction close to the friction component fixing platform 3, thereby increasing the gap between the friction block 6 and the clamped formed body and reducing the pressure applied to the clamped formed body, thereby reducing the friction between each other.

[0025] On the contrary, when the pressure / friction force applied by the friction block 6 on the clamped molded body is less than the process requirement, that is, the clamped molded body cannot be effectively clamped, phenomena such as inability to pull or slipping occur, and the forward and reverse screws 1 are rotated in the opposite direction, and the left wedge block 4 with the positive wire ear seat 2 and the right wedge block 8 with the reverse wire ear seat 9 slide toward each other at the same time, and the lower wedge block 5 moves along the guide pin in the direction away from the friction component fixing platform 3, thereby reducing the gap between the friction block 6 and the clamped molded body and increasing the pressure on the clamped molded body, thereby increasing the friction between each other.

[0026] In the description of the present invention, it is necessary to understand that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the present invention should still fall within the scope covered by the claims of the present invention.
