[0028] Referring to Figures 1 - 2 , which is the first embodiment of the present utility model. This embodiment provides a wire stripping tool, which includes a stripping unit 100 and a fixing unit 200. Through the mutual cooperation between the stripping unit 100 and the fixing unit 200, the clamping and fixing of the cable can be realized, which is beneficial for the operator to always cut along the axis direction of the cable, and at the same time ensure that the tool will not fall off, improving the safety during use.

[0029] Among them, the stripping unit 100 includes a first connecting rod 101, a grip 102 arranged at the tail of the first connecting rod 101, and a cutting assembly 103 connected to the first connecting rod 101.

When the knob 103b is aligned with the scale groove 101a at the top of the first connecting rod 101, the cutting knife 103b can cut along the axis direction of the cable. After the adjustment is completed, the operator pulls the grip 102 to complete the cable wire stripping work.

[0034] Embodiment 2

[0035] Referring to Figures 3 - 5, which is the second embodiment of the present utility model. This embodiment further provides that the first fixing component 201 includes a fixing member 201a, a fixing ball 201b, a connecting shaft 201c, and a mating tooth arm 201d. Through the mutual cooperation among the fixing member 201a, the fixing ball 201b, the connecting shaft 201c, and the mating tooth arm 201d, cables with different diameters can be fixedly clamped, and the cutting process becomes more labor-saving.

[0036] Among them, the fixing ball 201b is embedded in the inner ring side wall of the fixing member 201a; the mating tooth arm 201d is rotatably connected to the end of the fixing member 201a through the connecting shaft 201c.

[0037] Further, the fixing member 201a includes a square structure E and a semi-circular ring structure F.

[0038] Further, an opening 201a-1 is formed in the square structure E, and the opening 201a-1 extends towards the side wall of the square structure E to form a receiving cavity 201a-2. A second connecting rod 201a-3, a tooth groove 201a-4, a torsion spring 201a-5, and a lever 201a-6 are arranged in the receiving cavity 201a-2; a sliding groove 201a-7 is formed at the top of the square structure E.

[0039] Among them, the opening 201a-1 penetrates through the square structure E and extends to the side wall of the semi-circular ring structure F. The second connecting rod 201a-3 is fixedly arranged on the side wall of the receiving cavity 201a-2. A tooth groove 201a-4 is arranged at one end of the second connecting rod 201a-3 away from the receiving cavity 201a-2. One end of the torsion spring 201a-5 is connected to the second connecting rod 201a-3, and the other end is connected to the side wall of the receiving cavity 201a-2. The lever 201a-6 is fixedly connected to the tooth groove 201a-4 and extends to the top of the square structure E, and it can cooperate and slide in the sliding groove 201a-7.

[0040] Further, ball grooves 201a-8 are evenly formed on the side wall of the semi-circular ring structure F, and a rotation notch 201a-9 is formed through one end of the semi-circular ring structure F close to the connecting shaft 201c.

[0041] Further, the fixing ball 201b is movably arranged in the ball groove 201a-8; a part of the fixing ball 201b exposes out of the ball groove 201a-8.

[0042] Further, engaging teeth 201d-1 are arranged on the outer side wall of the mating tooth arm 201d, and the engaging teeth 201d-1 can be engaged with the tooth groove 201a-4; the mating tooth arm 201d is matched with the rotation notch 201a-9, and it can slide out from the opening 201a-1.

[0043] During operation, pass the cable through the second fixing component 202 and the first fixing component 201 in sequence. Push the engaging tooth arm 201d into the opening 201a-1, and engage the engaging tooth 201d-1 with the tooth groove 201a-4. After adjusting to the appropriate position, the fixing of the cable can be completed. If the diameter of the cable is large, the engaging tooth arm 201d can adjust the opening and closing angle at the rotating notch 201a-9 to adapt to the cable with a larger diameter.

[0044] After the cable is fixed, the fixing ball 201b closely adheres to the surface of the cable. Adjust the position and direction of the cutting component 103, and then the cutting operation can be carried out.

[0045] During the cutting process, the fixing ball 201b rolls synchronously along the movement direction of the cutting knife 103c, reducing the influence of friction on the cutting operation and facilitating the operation.

[0046] When the cable needs to be released, push the lever 201a-6 to move along the sliding groove 201a-7, which can drive the second connecting rod 201a-3 to move towards the inner wall direction of the accommodating cavity 201a-2, and at the same time compress the torsion spring 201a-5, so that the tooth groove 201a-4 is separated from the engaging tooth 201d-1. Then, the engaging tooth arm 201d can be rotated to disengage from the opening 201a-1 to complete the release of the cable. After releasing the lever 201a-6, the torsion spring 201a-5 is released and returns to its original state. Driven by it, the second connecting rod 201a-3 and the tooth groove 201a-4 will also return to their original positions to prepare for the next cutting operation.

[0047] Embodiment 3

[0048] Refer to Figure 2 , which is the third embodiment of the present utility model. This embodiment further provides that the grip 102 is made of insulating material, enhancing the wear resistance and flexibility of the wire stripping tool. Among them, the surface of its handheld part is provided with anti-slip lines 102a. In actual operation, even if the hand is stained with oil or water stains, it can ensure a firm grip and is not easy to slip off, further reducing the possibility of danger. The cutting component 103 and the fixing unit 200 are both made of metal material, preferably stainless steel material here, which is beneficial to improving the durability of the tool, avoiding the situation that the cutting tool suddenly breaks during the cutting process and causing harm to the operator, improving the use safety. At the same time, using stainless steel material can improve the sharpness of the tool, facilitate the stripping of the cable protective layer, and reduce the operation difficulty.

[0049] During operation, the insulating grip 102 can effectively prevent the operator from being accidentally electrocuted, and the anti-slip lines 102a provided on its surface can enhance the friction force and prevent it from falling off the hand. Selecting metal materials for the cutting knife 103 and the fixing unit 200 is beneficial for fixing and cutting the cable, and also improves the durability of the wire stripping tool.

[0050] It should be understood that, in the development of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without undue experimentation, such development efforts will be routine work of design, manufacturing, and production.
