Description

Technical Field

[0001] This utility model relates to the field of wire clamping tools, and in particular to a square-mouth wire clamping pliers. Background Technology

[0002] Square-jaw wire clamps are a common type of wire clamping tool. The structure of commonly used square-jaw wire clamps is shown in patent publication CN307092501S. This type of wire clamp mainly relies on four clamping blocks to form a square-jaw clamp to clamp the wire. Since the four clamping blocks are independently mounted on the handle by a pin, and the square clamp requires all four clamping blocks to be in good working order, if any one clamping block is damaged or jammed, the entire wire clamp cannot form a square clamp. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a square-mouth wire clamp that prevents the clamp from getting stuck during use and significantly reduces the probability of damage causing the clamp to fail to form.

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

[0005] A square-jaw wire clamp includes a first clamp handle, a second clamp handle, and a mounting pin. The first clamp handle and the second clamp handle are rotatably mounted on the mounting pin. It also includes clamp heads, of which there are two. The two clamp heads are respectively mounted on the first clamp handle and the second clamp handle. The clamp heads are provided with a plurality of first pressure plates and second pressure plates. The first pressure plates and second pressure plates on the same clamp head are parallel and do not contact each other. The first pressure plates and second pressure plates on the same clamp head form an angle of 90 degrees. The first pressure plates and second pressure plates on the two clamp heads are distributed in a square shape.

[0006] In this type of square-jaw wire clamp, a total of two clamp heads form a square jaw. The two clamp heads are respectively installed on the first clamp handle and the second clamp handle, and the clamp heads are installed in a fixed installation manner with the first clamp handle and the second clamp handle. After installation, when the first clamp handle and the second clamp handle are pressed, the two clamp heads move closer together, and the size of the square jaw formed is reduced. When the first clamp handle and the second clamp handle are no longer pressed, the two clamp heads move further apart, and the size of the square jaw formed is increased.

[0007] The first and second pressure plates on the two clamps are arranged in a square shape, which ensures that the clamping jaws formed by the first and second pressure plates are square.

[0008] In this type of wire clamp, both jaws are fixedly mounted on the first and second jaws, preventing them from rotating relative to the jaws. This significantly reduces the probability of the jaws jamming during use. Furthermore, the jaws are formed by the first and second clamping plates on both jaws, and the size of the jaws can be adjusted by bringing the jaws closer together or further apart. Each jaw has multiple first and second clamping plates, so damage to one plate does not affect the formation of the entire jaw. Therefore, this design makes the clamps more reliable.

[0009] In summary, this type of wire clamp will not experience clamping during use, and the probability of damage leading to a failure to form a clamp is greatly reduced.

[0010] Optionally, each pliers head is provided with a patch for attaching to a first or second pressure plate on another pliers head.

[0011] The patch is attached tightly to the first or second pressure plate on the other clamping head, which ensures greater stability when the two clamping heads move relative to each other.

[0012] Optionally, it also includes a mounting rod, wherein the pliers head is mounted on a first pliers handle or a second pliers handle via the mounting rod, and the two ends of the mounting rod are provided with retaining springs, which are close to the pliers head.

[0013] The mounting rod passes through the through holes in the pliers head and handle, and is then locked in place by a snap ring, thus locking the pliers head onto the handle.

[0014] Optionally, the pliers head is provided with a notch, and the pliers head is engaged with the first pliers handle or the second pliers handle through its notch.

[0015] The notch is used to clamp the first or second jaw, thereby ensuring that the jaw head is stably mounted on the first or second jaw.

[0016] Optionally, the first and second compression plates have the same shape and size, and the first compression plate is a triangular compression plate.

[0017] Optionally, the distance between two adjacent first pressing sheets is equal, and the distance between two adjacent first pressing sheets is greater than the thickness of the first pressing sheet; the distance between two adjacent second pressing sheets is equal, and the distance between two adjacent second pressing sheets is greater than the thickness of the second pressing sheet.

[0018] The above structure is designed to prevent the clamping plates from coming into contact with each other and causing friction as the clamping jaws increase or decrease in size, thus avoiding any impact on the size of the clamping jaws.

[0019] Optionally, the first clamp handle is rotatably provided with a locking piece, and the second clamp handle is provided with a locking port.

[0020] When the locking tab is engaged in the locking slot, the first and second clamps are locked together, and they cannot rotate relative to each other. When the locking tab is not engaged in the locking slot, the first and second clamps can rotate relative to each other.

[0021] Optionally, a spring is provided between the first clamp and the second clamp.

[0022] The beneficial effects of this utility model are: it will not cause the clamp to jam during use, and the probability of damage leading to the inability to form a clamp is greatly reduced. Attached Figure Description

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. 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.

[0031] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, a square-jaw wire clamp includes a first clamp handle 1, a second clamp handle 2, and a mounting pin. The first clamp handle 1 and the second clamp handle 2 are rotatably mounted on the mounting pin. It also includes clamp heads 8, of which there are two. The two clamp heads 8 are respectively mounted on the first clamp handle 1 and the second clamp handle 2. The clamp heads 8 are provided with a plurality of first pressure plates 11 and second pressure plates 12. The first pressure plates 11 and second pressure plates 12 on the same clamp head 8 are in a parallel and non-contact state. The first pressure plates 11 and second pressure plates 12 on the same clamp head 8 form an angle of 90 degrees. The first pressure plates 11 and second pressure plates 12 on the two clamp heads 8 are distributed in a square shape.

[0032] In this type of square-jaw wire clamp, a total of two clamp heads 8 form a square jaw. The two clamp heads 8 are respectively installed on the first clamp handle 1 and the second clamp handle 2, and the clamp heads 8 are installed in a fixed installation manner with the first clamp handle 1 and the second clamp handle 2. After installation, when the first clamp handle 1 and the second clamp handle 2 are pressed, the two clamp heads 8 move closer to each other, and the size of the square jaw formed is reduced. When the first clamp handle 1 and the second clamp handle 2 are no longer pressed, the two clamp heads 8 move further apart, and the size of the square jaw formed is increased.

[0033] The first pressing plate 11 and the second pressing plate 12 on the two clamping heads 8 are arranged in a square, which ensures that the clamping mouth formed by the first pressing plate 11 and the second pressing plate 12 is a square clamping mouth.

[0034] In this type of wire clamp, since both clamp heads 8 are fixedly mounted on the first clamp handle 1 and the second clamp handle 2, the clamp heads 8 cannot rotate relative to the first clamp handle 1 and the second clamp handle 2. This significantly reduces the probability of the clamp heads 8 getting stuck during use. Furthermore, the clamping jaws are formed by the first clamping plates 11 and the second clamping plates 12 on the two clamp heads 8, and the size of the clamping jaws can be adjusted by bringing the two clamp heads 8 closer together or further apart. Each clamp head 8 has multiple first clamping plates 11 and second clamping plates 12, so if one clamping plate is damaged, it does not affect the formation of the entire clamping jaws. Therefore, it is more reliable in use.

[0035] In summary, this type of wire clamp will not experience clamping during use, and the probability of damage leading to a failure to form a clamp is greatly reduced.

[0036] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, each clamping head 8 is provided with a patch 9, which is used to attach to the first pressure plate 11 or the second pressure plate 12 on another clamping head 8.

[0037] The patch 9 is attached to the first pressure plate 11 or the second pressure plate 12 on the other clamping head 8, which ensures greater stability when the two clamping heads 8 move relative to each other.

[0038] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, it also includes a mounting rod 6. The pliers head 8 is mounted on the first pliers handle 1 or the second pliers handle 2 via the mounting rod 6. The two ends of the mounting rod 6 are provided with retaining springs 7, which are close to the pliers head 8.

[0039] The mounting rod 6 passes through the through hole 13 on the pliers head 8 and the pliers handle, and then locks the mounting rod 6 with the help of the retaining spring 7, thereby locking the pliers head 8 onto the pliers handle with the mounting rod 6.

[0040] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, the pliers head 8 has a notch 10, and the pliers head 8 is clamped and engaged with the first pliers handle 1 or the second pliers handle 2 through its notch 10.

[0041] The notch 10 is used to clamp the first clamp handle 1 or the second clamp handle 2, thereby enabling the clamp head 8 to be stably installed on the first clamp handle 1 or the second clamp handle 2.

[0042] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, the first pressing plate 11 and the second pressing plate 12 have the same shape and size, and the first pressing plate 11 is a triangular pressing plate 11.

[0043] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, the distance between two adjacent first pressing sheets 11 is equal, and the distance between two adjacent first pressing sheets 11 is greater than the thickness of the first pressing sheet 11. The distance between two adjacent second pressing sheets 12 is equal, and the distance between two adjacent second pressing sheets 12 is greater than the thickness of the second pressing sheet 12.

[0044] The above structure is designed to prevent the clamping plates from coming into contact with each other and causing friction as the clamping jaws increase or decrease in size, thus avoiding any impact on the size of the clamping jaws.

[0045] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, a locking piece 4 is rotatably provided on the first clamp handle 1, and a locking port 5 is provided on the second clamp handle 2.

[0046] When the locking piece 4 is locked onto the locking slot 5, the first clamp 1 and the second clamp 2 are locked together, and the first clamp 1 and the second clamp 2 cannot rotate relative to each other. When the locking piece 4 is not locked onto the locking slot 5, the first clamp 1 and the second clamp 2 can rotate relative to each other.

[0047] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, a spring 3 is provided between the first clamp handle 1 and the second clamp handle 2.

[0048] The above-described embodiments only illustrate some aspects of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
