Description

Technical Field

[0001] This utility model relates to the field of clamping equipment, and in particular to a wire clamping clamp with a detachable clamp head. Background Technology

[0002] Wire clamps are a commonly used wire clamping device. To facilitate the replacement of different clamping heads to meet different wire clamping needs, current wire clamps often adopt a detachable installation method. Patent publication document CN221364484U discloses a type of wire clamp with a detachable clamping head. In this structure, the clamping head is secured to the handle by two locating pins of different diameters. Since the two locating pins need to both lock the clamping action and transmit force between the clamping head and the handle, the two locating pins in this type of wire clamp are prone to twisting and deformation during use. Once twisting and deformation occurs... Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a detachable clamping pliers. The clamping head can be removed or installed simply by rotating the locking pin. The clamping head and the clamp handle are supported by the positioning pin, which does not deform under stress during use. The locking is reliable and ensures that the clamping head can always be quickly removed from the clamp handle.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A detachable wire clamp includes clamp handles and locking pins. Two clamp handles are rotatably mounted on the locking pins. The clamp also includes a clamp head and a locking pin. The clamp head has a positioning pin, and the clamp handles have positioning holes. The positioning pin engages with the positioning holes. The locking pin is rotatably mounted on a through hole in the clamp handle. The clamp handle has a locking hole, which includes a circular hole and a straight hole. The straight hole is located on one side of the circular hole and connects to it. The locking pin is pressed against the wall of the circular hole. The locking pin has a pressing protrusion for pressing down on the clamp head.

[0006] In this type of wire clamp, the positioning hole is embedded in the positioning pin. The force between the clamp head and the clamp handle is transmitted through the positioning pin. The locking pin only presses the clamp head down with its own pressing protrusion. When the pressing protrusion presses down on the clamp head, the clamp head is pressed onto the clamp handle and cannot be detached from the clamp handle. However, when clamping the wire, the force between the clamp head and the clamp handle is transmitted through the positioning pin. The locking pin is not subjected to force when the clamp head is clamping the wire. This ensures that the locking pin will not deform during use and that the clamp head can always be quickly attached and detached from the clamp handle.

[0007] When you need to remove the pliers head from the handle, rotate the locking pin so that the pressing protrusion aligns with the straight hole. Then pull out the pliers head, causing the positioning hole to disengage from the positioning pin. During this process, the pressing protrusion passes through the straight hole, completely disengaging the positioning pin from the positioning hole. To reassemble, simply place the pliers head back on the handle, aligning the positioning pin with the positioning hole and the pressing protrusion with the straight hole. Then insert the positioning pin into the positioning hole, and rotate the locking pin again so that the pressing protrusion rotates relative to the straight hole, pressing the pliers head back into place. This completes the reassembly of the pliers head.

[0008] In summary, the pliers head of this type of wire clamp can be removed and installed simply by rotating the locking pin. The pliers head and the handle are supported by the positioning pin, and the locking pin will not deform during use without being subjected to force, ensuring reliable locking and guaranteeing that the pliers head can always be quickly removed and installed from the handle.

[0009] Optionally, there are two pressing protrusions, which are located at both ends of the locking post and are aligned in a straight line. There are also two straight holes, which are located on both sides of the circular hole and are aligned in a straight line.

[0010] Two pressing protrusions are provided, located on both sides of the locking post. Pressing the pliers head from both sides ensures high stability.

[0011] Optionally, each clamp head is provided with two positioning pins, and the two positioning pins are located on both sides of the locking pin, and the number of positioning holes is equal to the number of positioning pins.

[0012] The two positioning pins engage with the positioning holes to improve the stability of the pliers head on the pliers handle.

[0013] Optionally, one end of the locking pin is provided with an anti-disengagement sleeve, which is tightly fitted against the clamp handle.

[0014] The function of the anti-slip sleeve is to limit the locking pin from one end and prevent the locking pin from slipping off the clamp handle.

[0015] Optionally, the locking pin is perpendicular to the clamp handle, and the positioning pin is perpendicular to the clamp head.

[0016] The locking pin is used to connect the two pliers handles.

[0017] Optionally, the clamp handle is provided with a mating plane, and the clamp head is provided with a contact plane, with the mating plane closely abutting the contact plane.

[0018] The mating surface is pressed tightly against the contact surface to ensure that the pliers head is more stably mounted on the pliers handle.

[0019] Optionally, the positioning post is a circular positioning post, and the positioning hole is a circular positioning hole.

[0020] Optionally, it also includes a locking tab, which is rotatably mounted on one of the jaws and has a locking slot on the other jaw.

[0021] The function of the locking tab and the locking slot is to temporarily lock the two pliers handles. When one end of the locking tab is engaged with the locking slot, the two pliers handles are locked. When the locking tab is not engaged with the locking slot, the two pliers handles are in a state where they can rotate freely.

[0022] The beneficial effects of this utility model are: the pliers head can be disassembled and assembled simply by rotating the locking pin. The pliers head and the pliers handle are supported by the positioning pin. The locking pin will not deform during use as it is not subjected to force, ensuring reliable locking and guaranteeing that the pliers head can always be quickly disassembled and assembled from the pliers handle.

It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0030] As attached Figure 1 and appendix Figure 2 As shown, a detachable wire clamp with 10 pliers includes a clamp handle 1 and a locking pin 4. There are two clamp handles 1, both of which are rotatably mounted on the locking pin 4. The clamp also includes a clamp head 10 and a locking pin 8. The clamp head 10 is provided with a positioning pin 12, and the clamp handle 1 is provided with a positioning hole 14. The positioning pin 12 and the positioning hole 14 are fitted together. The locking pin 8 is rotatably mounted on a through hole on the clamp handle 1. The clamp handle 1 is provided with a locking hole, which includes a round hole portion 11 and a straight hole portion 9. The straight hole portion 9 is located on one side of the round hole portion 11 and is connected to the round hole portion 11. The locking pin 8 is close to the hole wall of the round hole portion 11. The locking pin 8 is provided with a pressing protrusion 7, which is used to press the clamp head 10.

[0031] In this type of wire clamp, the positioning hole 14 is embedded in the positioning post 12. The force between the clamp head 10 and the clamp handle 1 is transmitted through the positioning post 12. The locking post 8 only presses the clamp head 10 with its own pressing protrusion 7. When the pressing protrusion 7 presses the clamp head 10, the clamp head 10 is pressed onto the clamp handle 1, and the clamp head 10 cannot fall off the clamp handle 1. However, when clamping wire, the force between the clamp head 10 and the clamp handle 1 is transmitted through the positioning post 12. The locking post 8 is not under force when the clamp head 10 clamps wire. This ensures that the locking post 8 will not deform during use, and ensures that the clamp head 10 can always be quickly removed from the clamp handle 1.

[0032] When it is necessary to remove the pliers head 10 from the pliers handle 1, rotate the locking pin 8 so that the pressing protrusion 7 aligns with the straight hole 9, and then pull out the pliers head 10, so that the positioning hole 14 and the positioning pin 12 are disengaged. During this process, the pressing protrusion 7 passes through the straight hole 9, and the positioning pin 12 is completely disengaged from the positioning hole 14, thus completing the disassembly. When reassembly is required, simply place the pliers head 10 back on the pliers handle 1, align the positioning pin 12 with the positioning hole 14, and align the pressing protrusion 7 with the straight hole 9. Then insert the positioning pin 12 into the positioning hole 14, and then rotate the locking pin 8 again so that the pressing protrusion 7 rotates relative to the straight hole 9, and the pressing protrusion 7 presses the pliers head 10 again. At this point, the reassembly of the pliers head 10 is completed.

[0033] In summary, the pliers head 10 in this type of wire clamp can be disassembled and assembled simply by rotating the locking pin 8. The pliers head 10 and the pliers handle 1 are supported by the positioning pin 12. The locking pin 8 will not deform during use as it is not subjected to force, ensuring reliable locking and guaranteeing that the pliers head 10 can always be quickly disassembled and assembled from the pliers handle 1.

[0038] As attached Figure 1 and appendix Figure 2 As shown, one end of the locking post 8 is provided with an anti-disengagement sleeve 13, which is tightly attached to the clamp handle 1.

[0039] The function of the anti-slip sleeve 13 is to limit the locking pin 8 from one end and prevent the locking pin 8 from slipping off the clamp handle 1.

[0040] As attached Figure 1 and appendix Figure 2As shown, the locking pin 4 is perpendicular to the clamp handle 1, and the positioning pin 12 is perpendicular to the clamp head 10.

[0041] The function of the locking pin 4 is to connect the two pliers handles 1.

[0042] As attached Figure 1 and appendix Figure 2 As shown, the clamp handle 1 is provided with a mating surface 5, and the clamp head 10 is provided with a contact surface 6, with the mating surface 5 closely mating to the contact surface 6.

[0043] The mating plane 5 is pressed tightly against the contact plane 6 to ensure that the pliers head 10 is installed more stably on the pliers handle 1.

[0044] As attached Figure 1 and appendix Figure 2 As shown, the positioning post 12 is a circular positioning post 12, and the positioning hole 14 is a circular positioning hole 14.
