Abstract
Description
Technical Field
[0001] This utility model relates to the field of tool structure, specifically to a tool structure for a wire stripper. Background Technology
[0002] Newly installed electricity meters often require live connection to the household. Normally, frontline construction workers use an electrician's knife to strip the insulation from the low-voltage wires before connecting them. However, the process of stripping the insulation with a knife is relatively cumbersome and involves a large range of motion. Furthermore, the environment at the connection site varies, such as under the eaves of buildings with advertising signs, at corners, or on high low-voltage lines. These locations pose significant safety hazards for live operations, so a wire stripper is used instead.
[0003] During the wire stripping process, the wire stripper needs to rotate the stripping blades. For example, when stripping the outer sheath of the wire, the sheath needs to be cut along the wire axis first, and then cut along the circumference of the wire a second time to completely remove the sheath. After long-term use, the blade head is prone to wear and failure. In the existing wire stripper blade structure, the blade head and blade shank are integrally formed. If the blade head needs to be replaced, the entire wire stripper needs to be disassembled, which is very time-consuming and labor-intensive. Utility Model Content
[0004] To address the aforementioned problems, this application provides a tool structure for a wire stripper, comprising a tool shank and a blade. The tool shank includes a rod body, a connecting seat at the bottom of the rod body, and a connecting platform at the bottom of the connecting seat. The connecting platform includes a connecting surface parallel to the axial direction of the rod body. The blade includes a cutting face that fits against the connecting surface. A limiting member protrudes outward from the connecting surface, and a support member is provided above the limiting member. The limiting member includes a limiting portion and a connecting portion. A first through hole is formed on the cutting face, and a second through hole communicating with the first through hole is formed below the first through hole.
[0005] Furthermore, a first limiting groove is formed between the limiting part and the connecting surface. The first limiting groove is located on both sides of the connecting part. A first snap-fit part is provided on both sides of the second through hole. When the second through hole enters the connecting part, the first snap-fit part is embedded in the first limiting groove.
[0006] Furthermore, a support surface is provided on the top of the support member, and when the blade and the connecting surface are in contact with each other, the upper edge of the first through hole is supported on the support surface.
[0007] Furthermore, a second limiting groove is formed by an upward recess at the bottom of the connecting seat, and a second snap-fit portion is protruding at the top of the blade. When the upper edge of the first through hole supports the supporting surface, the second snap-fit portion is embedded in the second limiting groove.
[0008] Furthermore, a third through hole is provided on the connecting platform, which passes through the second limiting groove and corresponds to the position of the second snap-fit part.
[0009] Furthermore, a slope is provided on the side of the support member.
[0010] Furthermore, a fourth through hole is provided above the first through hole, and a third snap-fit part is provided on both sides of the fourth through hole.
[0011] Furthermore, a fifth through hole is provided on the connecting platform. When the upper edge of the first through hole rests on the supporting surface, the position of the fifth through hole passing through the connecting surface corresponds to that of the first through hole.
[0012] The beneficial effects of this utility model are as follows:
[0013] This application enables the wire stripper's blade to be disassembled and assembled by setting a limiting component on the connecting platform and setting a first through hole and a second through hole on the blade. When the blade is damaged, it can be removed from the blade holder with a simple tool. When installing the blade, simply insert the new blade into the bottom of the wire stripper and support it on the limiting component. Assembly is convenient and simple.

[0029] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0030] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings. Figures 1 to 3 As shown, the tool structure for a wire stripper includes a tool bar 10 and a blade 20. The tool bar 10 includes a rod body 100, a connecting seat 200 is provided at the bottom of the rod body 100, and a connecting platform 300 is provided at the bottom of the connecting seat 200. The connecting platform 300 includes a connecting surface 310, which is parallel to the axial direction of the rod body 100. The blade 20 includes a cutting face 400, which is in contact with the connecting surface 310. A limiting member 320 protrudes outward on the connecting surface 310. A support member 330 is provided above the limiting member 320. The limiting member 320 includes a limiting part 321 and a connecting part 322. A first through hole 410 is provided on the cutting face 400, and a second through hole 420 communicating with the first through hole 410 is provided below the first through hole 410.
[0031] During assembly in this embodiment, as shown by arrow A in Figure 2, the first through hole 410 on the blade 400 is first passed through the limiting member 320. After the blade 400 passes through the limiting member 321, as shown by arrow B in Figure 3, the blade 400 is pulled up to suspend the first through hole 410 on the support member 330. At this time, the second through hole 420 enters the connecting part 322, and the second through hole 420 clamps the connecting part 322, thereby fixing the entire blade 20 and the connecting surface 310.
[0032] Compared with the prior art, this application provides a limiting member 320 on the connecting platform 300 and a first through hole 410 and a second through hole 420 on the blade 20, so that the blade of the wire stripper can be disassembled and assembled. When the blade is damaged, the blade 20 can be removed from the blade bar 10 with a simple tool. When installing the blade 20, the new blade 20 is simply inserted into the bottom of the wire stripper and supported on the limiting member 320. The assembly is convenient and simple.
[0033] Furthermore, based on the above embodiments, combined with Figure 4 and Figure 6 As shown, a first limiting groove 323 is formed between the limiting part 321 and the connecting surface 310. The first limiting groove 323 is located on both sides of the connecting part 322. A first snap-fit part 421 is provided on both sides of the second through hole 420. When the second through hole 420 enters the connecting part 322, the first snap-fit part 421 is embedded in the first limiting groove 323, thereby causing the second through hole 420 to clamp the connecting part 322.
[0034] Furthermore, based on the above embodiments, combined with Figure 4 and Figure 6 As shown, a support surface 331 is provided on the top of the support member 330. When the blade 400 and the connecting surface 310 are in contact with each other, the upper edge of the first through hole 410 is supported on the support surface 331, so that the entire blade 20 can be suspended on the support member 330.
[0035] Furthermore, based on the above embodiments, combined with Figure 4 and Figure 6 As shown, a second limiting groove 210 is recessed upward at the bottom of the connecting seat 200, and a second snap-fit portion 430 is protruding at the top of the blade surface 400. When the upper edge of the first through hole 410 supports the supporting surface 331, the second snap-fit portion 430 is embedded in the second limiting groove 210, thereby forming a clamping state with the second through hole 420 on the connecting portion 322, so that the entire blade 20 and the connecting surface 310 are fixed together.
[0036] Furthermore, based on the above embodiments, combined with Figure 5 and Figure 6 As shown, a third through hole 340 is provided on the connecting platform 300. The third through hole 340 passes through the second limiting groove 210 and corresponds to the position of the second locking part 430. When it is necessary to disengage the cutting edge 400 from the connecting surface 310, a rod-shaped object is used to pass through the third through hole 340 from the side away from the connecting surface 310, thereby pushing the second locking part 430 out of the second limiting groove 210. During this pushing process, the upper edge of the first through hole 410 also disengages from the supporting surface 331, causing the entire cutting tool to fall into the limiting member 320, thus completing the disassembly of the cutting tool.
[0037] Furthermore, based on the above embodiments, such as Figure 4 As shown, a slope 332 is provided on the side of the support member 330. When the first through hole 410 on the blade 400 passes through the limiting member 320, and then the blade 400 as a whole passes through the limiting part 321, and then the blade 400 is pulled up, the slope 332 can better allow the blade 400 to pass through the side of the support member 330, and finally the upper edge of its first through hole 410 is supported on the support surface 331.
[0038] Furthermore, based on the above embodiments, such as Figure 6 As shown, a fourth through hole 440 is provided above the first through hole 410, and third locking portions 441 are provided on both sides of the fourth through hole 440. Thus, when the entire tool falls onto the limiting member 320, the fourth through hole 440 can be inserted into the connecting portion 322, and the third locking portions 441 can be inserted into the first limiting groove 323, preventing the tool from shaking when falling onto the limiting member 320, thereby allowing the tool to be completely removed from the limiting member 320.
[0039] Furthermore, based on the above embodiments, combined with Figure 5 and Figure 7 As shown, a fifth through hole 350 is provided on the connecting platform 300. When the upper edge of the first through hole 410 rests on the supporting surface 331, the fifth through hole 350 passes through the connecting surface 310 and corresponds to the position of the first through hole 410. The fifth through hole 350 is used to install the positioning rod 351 and cooperates with the base 30 of the wire stripper to limit the rotation range of the rod 100. This is not very relevant to the protection scope of this application, so it will not be described in detail.
[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
