Description

Technical Field

[0001] This utility model belongs to the field of wire harness cutting technology, specifically relating to a pair of pliers for cutting wire harnesses at equal intervals. Background Technology

[0002] Wiring harnesses play a crucial role in many fields such as automobiles, electronic devices, and home appliances, enabling power transmission and signal transmission between various electrical components.

[0003] Different electrical equipment or circuit systems have specific requirements for the length of connecting wire harnesses. During the manufacturing process, the wire harness needs to be cut to an appropriate length according to the actual installation location and connection requirements to ensure that the wire harness can accurately connect the various components without being too long and causing waste or tangling. This requires the use of pliers to cut the wire harness.

[0004] Chinese patent CN206276970U discloses a pair of pliers for equidistant wire cutting. The specification describes a method where a first electromagnet is de-energized, the shaft is removed, the wire harness is wound around the shaft, and the shaft is returned to its original position while simultaneously energizing both the first and second electromagnets. This causes the electromagnets to have opposite magnetic properties, attracting each other and thus fixing the shaft. After fixing the shaft, the end of the wire harness is pulled out, passed through a through hole, and then pulled to the left until it is positioned outside the operating plate. The right side of the handle is then pressed down, causing the handle to move downwards. This downward movement compresses the spring, causing the pliers to move upwards. Releasing the handle releases the spring, causing it to extend upwards and move the pliers downwards to cut the wire harness on the operating plate.

[0005] In the aforementioned application, when cutting the wire harness, it is necessary to first remove the spool, wind the wire harness around it, put the spool back in, stabilize the spool with an electromagnet, and then cut the wire harness. The operation is cumbersome and inconvenient. Utility Model Content

[0006] The purpose of this invention is to provide a pair of pliers for cutting wire harnesses at equal intervals, so as to solve the problem that existing pliers are not convenient for cutting wire harnesses at equal intervals.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A pair of pliers for equidistant wire harness cutting includes a pliers body. An auxiliary mechanism is provided on the surface of the pliers body. The auxiliary mechanism includes a cylinder fixedly connected to the surface of the pliers body. A mounting plate is rotatably connected to the arc surface of the cylinder. A concave block is fixedly connected to the surface of the mounting plate. A multi-stage telescopic rod is rotatably connected to the inner wall of the concave block. A fixing plate is fixedly connected to the output end of the multi-stage telescopic rod.

[0009] Preferably, a limiting groove is provided on the side of the fixing plate near the concave block.

[0010] Preferably, the cylindrical arc surface is threaded with a threaded ring, and the threaded ring is in contact with the surface of the mounting plate.

[0011] Preferably, a spring is fixedly connected to the surface of the pliers body, and the two ends of the spring are respectively fixedly connected to the two pliers arms of the pliers body.

[0012] Preferably, each stage of the multi-stage telescopic rod is equipped with damping.

[0013] Preferably, the inner wall of the limiting groove is provided with anti-slip stripes.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model utilizes a multi-stage telescopic rod to adjust the length of the wire harness to be cut as needed. The wire harness head is held in place by a fixing plate and a limiting groove. Each cut causes the wire harness to press against the inner wall of the limiting groove, achieving the effect of equidistant cutting.

[0016] 2. This utility model can store the multi-stage telescopic rod by rotating the multi-stage telescopic rod and the mounting plate, so as to avoid the multi-stage telescopic rod affecting the normal use of the pliers body when equidistant cutting is not required. With the help of the spring force, the two lead arms can quickly rebound after the pliers body has finished cutting, which is convenient for the operator. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 As shown, this utility model provides a pair of pliers for equidistant wire harness cutting, including a pliers body 1. An auxiliary mechanism 2 is provided on the surface of the pliers body 1. The auxiliary mechanism 2 includes a cylinder 201 fixedly connected to the surface of the pliers body 1. A mounting plate 202 is rotatably connected to the arc surface of the cylinder 201. A concave block 203 is fixedly connected to the surface of the mounting plate 202. A multi-stage telescopic rod 204 is rotatably connected to the inner wall of the concave block 203. A fixing plate 205 is fixedly connected to the output end of the multi-stage telescopic rod 204. A limiting groove 206 is formed on the side of the fixing plate 205 near the concave block 203, and the inner wall of the limiting groove 206 is provided with anti-slip stripes.

[0024] It should be noted that each cut causes one end of the wire harness to press against the inner wall of the limiting groove 206, achieving the effect of equidistant cutting. The anti-slip stripes increase the friction between the wire harness and the anti-slip stripes.

[0025] In an optional embodiment, the arc surface of the cylinder 201 is threaded with a threaded ring 207, which is in contact with the surface of the mounting plate 202.

[0026] It should be noted that the threaded ring 207 serves to stabilize the angle of the mounting plate 202. The rotation of the mounting plate 202 and the multi-stage telescopic rod 204 can be stored in the multi-stage telescopic rod 204, so as to avoid the multi-stage telescopic rod 204 affecting the normal use of the pliers body 1 when equidistant cutting is not required.

[0027] In an optional embodiment, a spring 208 is fixedly connected to the surface of the pliers body 1, and the two ends of the spring 208 are fixedly connected to the two pliers arms of the pliers body 1 respectively.

[0028] It should be noted that the spring 208 serves to facilitate the rapid rebound of the two lead arms after the pliers body 1 has finished cutting, making it easier for workers to use.

[0029] In an optional embodiment: each stage of the multi-stage telescopic rod 204 is provided with damping.

[0030] It should be noted that, without the action of external force, the multi-stage telescopic rod 204 is not prone to slippage between each stage.

[0031] The working principle of this utility model is as follows: In use, the operator first screws on the threaded ring 207, causing the threaded ring 207 to disengage from the surface of the mounting plate 202 by means of the thread drive. Then, the mounting plate 202 is rotated, followed by rotating the angle of the multi-stage telescopic rod 204, such as... Figure 2 As shown, the threaded ring 207 is then twisted in the opposite direction to press it against the surface of the mounting plate 202, thus stabilizing the mounting plate 202. Next, the wire harness is placed between the two blades on the pliers body 1, and the length of the multi-stage telescopic rod 204 is adjusted according to the required cutting length. After adjustment, one end of the wire harness is pressed against the inside of the limiting groove 206, and the two lead arms of the pliers body 1 can be pressed to cut the wire harness. The spring 208 facilitates the rebound of the two lead arms of the pliers body 1. In this way, the wire harness is pressed against the inner wall of the limiting groove 206 with each cut, achieving the effect of equidistant cutting.
