Description

Technical Field

[0001] This utility model belongs to the technical field of electrical wire stripping tools, and relates to a portable electrical wire stripping tool. Background Technology

[0002] Electrician wire strippers are one of the commonly used tools by electricians. They are used to strip the surface insulation layer of the wire ends. Electrician wire strippers can separate the cut insulation from the wire.

[0003] One existing portable wire stripper has a straight blade capable of cutting wires smaller than 1.5 square millimeters. Alternatively, the blade can be opened to insert wires larger than 6 square millimeters. By holding the right side of the stripper with the right hand, tilting the stripper at a 45-degree angle to the wire, holding the wire with the left hand, and using the right hand to forcefully strip the insulation of the wire downwards to remove the insulation.

[0004] However, the above technical solutions and existing technologies have the following drawbacks:

[0005] Although this electrical wire stripping tool can strip wires, in actual use, the user needs to forcefully open and close the main structural components to allow the straight blade to embed into the insulation of the wire for stripping. This results in the tool consuming a lot of the user's physical strength, and its practicality needs to be improved. Utility Model Content

[0006] The purpose of this utility model is to provide a portable electrical wire stripping tool to address the problems existing in the prior art, thereby solving the problems that the sampler cannot classify and store soil and has low ease of use.

[0007] Therefore, the present invention adopts the following technical solution:

[0008] A portable wire stripping tool includes an upper stripping plate, a through cavity, wire stripping jaws, a lower stripping plate, and a cutting blade. The lower stripping plate is attached to the lower end face of the upper stripping plate. Both the upper and lower stripping plates have through cavities. Wire stripping jaws are provided on the lower end face of the upper stripping plate and the upper end face of the lower stripping plate. A cutting blade is provided on the left side of the lower end face of the upper stripping plate. Pulling components are symmetrically arranged on the left and right sides of the lower end face of the upper stripping plate, and the pulling components are used to apply a downward pulling force to the upper stripping plate so that the wire stripping jaws can strip external wires more easily. Adjustment components are symmetrically arranged on the left and right sides inside the lower stripping plate, and the adjustment components are used to adjust the pulling strength of the pulling components.

[0009] Preferably, the pulling assembly includes a pulling spring, a limiting cover, a connecting rod, and a limiting cavity. Connecting rods are symmetrically arranged on the left and right sides of the lower end face of the upper wire stripper, and the lower end of the connecting rod is connected to the pulling spring. Limiting cavities are symmetrically opened on the left and right sides inside the lower wire stripper, and limiting covers are symmetrically installed on the left and right end faces of the lower wire stripper.

[0010] Preferably, the adjustment assembly includes an adjusting threaded rod, an adjusting block, a connecting block, and an internally threaded through hole. The lower stripper plate has symmetrically opened internally threaded through holes on its left and right sides. An adjusting threaded rod is provided inside the internally threaded through hole. A connecting block is provided at the upper end of the adjusting threaded rod, and an adjusting block is provided on the upper surface of the connecting block.

[0011] Preferably, an anti-detachment cover is installed at the middle position of the lower end face of the adjusting block, and the connecting block is cylindrical in shape.

[0012] Preferably, the lower end of the adjusting threaded rod is provided with a nut, and the annular side of the nut is provided with anti-slip texture, and the lower end face of the lower stripper plate is symmetrically provided with grooves on the left and right sides.

[0013] Preferably, a limiting block is provided on the lower side of the right end face of the connecting rod, a limiting groove is provided on the inner wall of the limiting cover, and the limiting groove matches the limiting block.

A cutting groove is provided on the left side of the upper surface of the lower stripping plate, and the cutting groove matches the cutting blade.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. In the process of stripping external wires with the upper and lower stripping plates, the pull spring will apply a downward force to the upper stripping plate through the connecting rod, causing the upper stripping plate to move down automatically and merge with the lower stripping plate. At this time, the stripping jaws will cut into part of the insulation of the external wire. Then, the user only needs to apply a small amount of force to perform the stripping operation, which reduces the physical strength of the user when stripping the wire and has good practicality.

[0017] 2. This utility model allows users to adjust the pulling force of the pull spring by rotating the adjusting threaded rod forward or backward, thereby moving the adjusting block upward or downward through the connecting round block. This makes it convenient for users to match and adjust the pulling force of the pull spring according to their own usage habits or the thickness of the insulation of the external wires.

[0030] 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.

[0031] Please see Figure 1-7 This utility model provides a technical solution:

[0032] Example 1:

[0033] A portable electrical wire stripping tool includes an upper stripping plate 1, a cavity 2, stripping jaws 3, a lower stripping plate 4, and a cutting blade 8. The lower stripping plate 4 is attached to the lower end face of the upper stripping plate 1. A cavity 2 is provided inside both the upper stripping plate 1 and the lower stripping plate 4. The cavity 2 allows the user's thumb or forefinger to easily open and close the upper stripping plate 1 or the lower stripping plate 4. Soft rubber sheets 21 are adhered to the upper and lower sides of the inner wall of the cavity 2 to improve the comfort of using the cavity 2. Stripping jaws 3 are provided on the lower end face of the upper stripping plate 1 and the upper end face of the lower stripping plate 4. The stripping jaws 3 are formed by two symmetrically structured tool steel blades with split edges. The stripping jaws 3 formed by two symmetrically structured tool steel blades with split edges are mainly capable of stripping the insulation of 1.0, 1.5, 2.5, and 4 square millimeter wires.

[0034] A cutting blade 8 is provided on the left side of the lower end face of the upper wire stripper 1, and a cutting groove 9 is provided on the left side of the upper end face of the lower wire stripper 4. The cutting groove 9 matches the cutting blade 8. The matching cutting groove 9 and cutting blade 8 will cut the external wire. Both the lower wire stripper 4 and the upper wire stripper 1 have carrying holes 5 inside. The carrying holes 5 make it convenient for external hanging ropes to be connected to the upper wire stripper 1 or the lower wire stripper 4 respectively, so as to facilitate the user to carry the upper wire stripper 1 and the lower wire stripper 4.

[0035] The upper wire stripper 1 has symmetrical pull components 7 on the left and right sides of its lower end face. The pull components 7 are used to apply downward pulling force to the upper wire stripper 1 so that the wire stripping jaws 3 can strip external wires more easily. The lower wire stripper 4 has symmetrical adjustment components 6 on the left and right sides inside. The adjustment components 6 are used to adjust the pulling strength of the pull components 7.

[0036] The pull assembly 7 includes a pull spring 71, a limiting cover 72, a connecting rod 73, and a limiting cavity 74. The connecting rods 73 are symmetrically arranged on the left and right sides of the lower end face of the upper stripper plate 1. The connecting rods 73 are connected to the upper stripper plate 1 by welding. The connecting rods 73 prevent the upper stripper plate 1 from slipping or shaking during use. The lower end of the connecting rod 73 is connected to the pull spring 71, which applies a downward pulling force to the connecting rod 73.

[0037] The lower wire stripper plate 4 has symmetrically arranged limiting cavities 74 on its left and right sides. The limiting cavities 74 are matched with the connecting rod 73 and the adjusting block 64 respectively. The limiting cavities 74 not only facilitate the use of the connecting rod 73 and the adjusting block 64 inside the lower wire stripper plate 4, but also limit and guide the connecting rod 73 and the adjusting block 64. The lower wire stripper plate 4 has symmetrically installed limiting covers 72 on its left and right ends. The limiting covers 72 are detachable. The detachable limiting covers 72 facilitate the disassembly and replacement of the pull spring 71 by the user. A limiting block 75 is provided on the lower right end face of the connecting rod 73. A limiting groove 721 is opened in the inner wall of the limiting cover 72. The limiting groove 721 matches the limiting block 75. The matching limiting groove 721 and the limiting block 75 prevent the connecting rod 73 from slipping during use. The pull spring 71 has connecting rings 711 at both the upper and lower ends. The connecting rings 711 facilitate the connection of the pull spring 71 to the connecting rod 73 and the adjusting block 64 respectively.

[0038] Example 2:

[0039] Based on Embodiment 1, in this embodiment, by rotating the adjusting threaded rod 63 forward or backward, the adjusting threaded rod 63 can drive the adjusting block 64 to move upward or downward through the connecting round block 65, thereby adjusting the pulling force of the pull spring 71. This allows users to adjust the pulling force of the pull spring 71 according to their own usage habits or the thickness of the insulation of the external wire.

[0040] The adjustment assembly 6 includes an adjusting threaded rod 63, an adjusting block 64, a connecting block 65, and an internally threaded through hole 66. The lower stripper plate 4 has symmetrically arranged internally threaded through holes 66 on its left and right sides. These through holes 66 mesh with the adjusting threaded rod 63, and the adjusting threaded rod 63 is housed inside the through hole 66. The adjusting threaded rod 63, connecting block 65, and nut 61 are all connected by welding. The meshing internally threaded through hole 66 and adjusting threaded rod 63 facilitate the up-and-down movement of the adjusting block 64. A connecting block 65 is located at the upper end of the adjusting threaded rod 63. The connecting block 65 is cylindrical in shape, which not only facilitates the adjustment of the adjusting rod 63 in moving the adjusting block 64 up and down but also prevents the adjusting block 64 from rotating together with the adjusting threaded rod 63.

[0041] An adjusting block 64 is provided on the upper end face of the connecting block 65. The adjusting block 64 applies a downward pulling force to the pull spring 71 through the connecting ring 711 below. An anti-disengagement cover 641 is installed in the middle of the lower end face of the adjusting block 64 to prevent the connecting block 65 from slipping during use. A nut 61 is provided at the lower end of the adjusting threaded rod 63. The nut 61 allows the user to rotate the adjusting threaded rod 63 by hand. The annular side of the nut 61 is provided with anti-slip texture, which improves the anti-slip performance of the annular side of the nut 61. The lower end face of the lower stripper plate 4 is symmetrically provided with notches 62 on the left and right sides. The notches 62 allow the user to rotate the nut 61 inside the lower stripper plate 4.

[0042] Working principle: When it is necessary to strip external wires, the user first holds the external wire to be stripped with one hand, and inserts the thumb and forefinger of the other hand into the through cavity 2 inside the upper stripping plate 1 and the lower stripping plate 4 respectively. At this time, an outward pushing force is applied to move the upper stripping plate 1 upward, while the lower stripping plate 4 moves downward and separates from the upper stripping plate 1 (see reference). Figure 6 Next, place the external wire to be stripped into the corresponding stripper jaws 3, then apply inward pushing force with your thumb and forefinger to move the upper stripper plate 1 and the lower stripper plate 4 inward and merge them (see reference). Figure 1 The wire stripper jaws 3 cut into the insulation of the external wire, and then a backward force is applied to the upper stripper plate 1 and the lower stripper plate 4, so that the wire stripper jaws 3 can peel off the cut insulation, thereby stripping the external wire. During this process, the pull spring 71 applies a downward pulling force to the connecting rod 73 through the connecting ring 711, so that the connecting rod 73 applies a downward pulling force to the upper stripper plate 1, making it easier for the upper stripper plate 1 to move down and merge with the lower stripper plate 4, thereby reducing the force required by the user when stripping the wire. At the same time, the limiting groove 721 limits the limiting block 75 to prevent the connecting rod 73 from slipping during use, and the limiting cavity 74 limits the connecting rod 73 to prevent the upper stripper plate 1 from shifting or shaking during opening and closing.

[0043] When the pulling force of the pull spring 71 needs to be adjusted, the user only needs to pinch the nut 61 and rotate it clockwise. This will cause the nut 61 to rotate clockwise along with the adjusting threaded rod 63. The adjusting threaded rod 63 will then move the adjusting block 64 upward through the connecting block 65. At this time, the pulling force of the pull spring 71 will be weakened. Similarly, when the adjusting threaded rod 63 is rotated counterclockwise, the adjusting block 64 will apply a downward pulling force to the pull spring 71 through the connecting ring 711. At this time, the pulling force of the pull spring 71 will be strengthened. This allows the user to adjust the pulling force of the pull spring 71 according to their own usage habits or the thickness of the insulation of the external wire, making the wire stripper jaws 3 more labor-saving and convenient when stripping wires.
