Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of power tools, and in particular to a wire stripper. Background Art

[0002] Wire strippers are usually used to assist electricians in cutting wires and stripping the surface insulation layer of the wire heads. An existing wire stripper includes a pair of first and second pliers bodies, the middle parts of which are hinged to each other and the two ends are respectively configured to form a pliers mouth and a handle. In order to adapt to wires of different thicknesses, the pliers mouth is also provided with working holes of different apertures, and the inner wall of the working hole is provided with a wire stripping blade. When the handle is pressed, the pliers mouth is engaged and the wire stripping blade just cuts off the insulation layer of the wire, thereby achieving the stripping of the insulation layer without damaging the wire core.

[0003] However, the size of the wire stripper's jaws is limited, the number of working holes that can be set is limited, and the types of wires that can be adapted during actual use are limited. There are still frequent situations where the insulation layer is not cut through or is over-cut, thereby damaging the wire core, making operation inconvenient. Utility Model Content

[0004] The technical problem to be solved by the embodiment of the utility model is to provide a wire stripper that can flexibly adjust the spacing between the wire stripping blades to match more types of wires.

[0006] Furthermore, a positioning block for limiting the minimum spacing between the stripping blades is provided between the blade holders of the two groups of the stripping assemblies.

[0007] Furthermore, the gap is a wedge-shaped gap which is narrow at one end close to the stripping blade and wide at one end away from the stripping blade. When the adjusting member moves toward the end close to the stripping blade, the elastic compression amount of the first elastic member increases, thereby closing the distance between the two stripping blades.

[0008] Furthermore, the adjusting member includes a pad block arranged in contact with the movable block and an adjusting buckle slidably connected to the pad block. A sliding groove is provided on a side of the pad block away from the movable block, and the adjusting buckle has a sliding block protruding from the sliding groove. The adjusting buckle is slidably connected to the pad block by embedding the sliding block in the sliding groove.

[0009] Furthermore, an operating portion is protruded from one end of the adjustment buckle, and an adjustment hole for exposing the operating portion is formed on a side wall of the installation cavity.

[0010] Furthermore, a locking tooth is formed in the middle of the adjustment buckle, and a rack is provided on the side wall of the installation cavity corresponding to the locking tooth. The adjustment buckle relatively fixes the adjustment position by locking the locking tooth into the corresponding tooth groove on the rack.

[0011] Furthermore, the ends of the knife holders of the two groups of the stripping assemblies away from the stripping blades are respectively provided with mounting holes, and the two ends of the first elastic member are respectively elastically abutted against the mounting holes on the corresponding sides to drive the knife holders to open outward accordingly.

[0012] Furthermore, a wire cutting opening is provided on the outer side of the first pliers body, and a static wire cutting blade is fixed in the first pliers body with the blade exposed from the wire cutting opening. The first pliers body is hingedly connected to a third pliers body by a connecting rod at one end of the first pivot away from the wire stripping blade. A dynamic wire cutting blade is provided on the top of the third pliers body corresponding to the static wire cutting blade. The third pliers body is pressed and moved toward the first pliers body to drive the dynamic wire cutting blade to move toward the static wire cutting blade.

[0013] Furthermore, a handle is extended from the end of the first pliers body toward the second pliers body, and the second pliers body is correspondingly embedded in the first pliers body and a U-shaped groove is formed at the end. One end of the connecting rod is hinged to the third pliers body and the opposite end is hinged to a roller through a third pivot. The connecting rod is embedded in the U-shaped groove and is abutted against the second pliers body by the roller. The third pliers body is pressed so that the connecting rod pushes the third pivot to move along the extension direction of the connecting rod, thereby causing the roller to push the second pliers body to pivot around the first pivot in a direction away from the third pliers body, and then the end of the second pliers body away from the U-shaped groove pivots and engages in a direction close to the first pliers body.

[0014] Furthermore, a wire pressing block is respectively fixed to the top of the first pliers body and the top of the second pliers body, and the ends of the knife holders of the two groups of the wire stripping assemblies are hinged by a second pivot, and another connecting piece is sequentially sleeved and connected to the second pivot, the first pivot and the third pivot, and a long slot hole is opened in the middle part of the connecting piece corresponding to the first pivot, and a second elastic piece is also sleeved on the part of the connecting piece located between the first pivot and the third pivot, and the third pliers body is pressed so that the connecting rod pushes the third pivot to move along the extension direction of the connecting rod and then drives the connecting piece to move in the direction away from the wire stripping blade, and the second pliers body drives the two wire stripping blades to close relative to each other and the second pivot follows the connecting piece to move away from one end of the wire stripping blade, and the wire stripping blades bite each other and move toward the first pivot to realize the stripping of the insulation layer of the wire.

[0015] After adopting the above technical scheme, the embodiment of the utility model has at least the following beneficial effects: the embodiment of the utility model provides an adjustment member for moving in the gap between the movable block and the bottom wall of the installation cavity to apply different thrusts to the first elastic member that elastically connects the two groups of stripping assemblies. The first elastic member contracts accordingly due to the thrust to produce different elastic compression amounts, thereby changing the opening and closing size between the stripping blades to adapt to wires of different diameters.

[0022] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention. In addition, the embodiments and features in the embodiments of the present application may be combined with each other without conflict.

[0023] like Figure 1-Figure 6 As shown, an optional embodiment of the utility model provides a wire stripping pliers, including a pair of first pliers body 1a and second pliers body 1b hingedly connected by a first pivot 1c, the first pliers body 1a and the second pliers body 1b are both provided with an installation cavity 10, each of the installation cavities 10 is respectively installed with a group of stripping components 3 and the stripping components 3 are elastically connected by a first elastic member 4, the stripping components 3 include a knife holder 30, a stripping blade 32 assembled on the top of the knife holder 30, and an end of the knife holder 30 close to the bottom wall of the installation cavity 10 and away from the stripping blade 32 is pivotally connected to the installation cavity 10 The movable block 34 on the side wall of the installation cavity 10, at least one group of the stripping assemblies 3 is also provided with an adjusting member 5 for adjusting the spacing between the stripping blades 32 and the stripping blades 32 of another group of the stripping assemblies 3, one side of the adjusting member 5 is attached to the side wall of the movable block 34 away from the knife holder 30 and the opposite side is abutted against the bottom wall of the installation cavity 10, the adjusting member 5 moves in the gap 12 between the movable block 34 and the bottom wall of the installation cavity 10 to apply different thrusts to the first elastic member 4 and the different elastic compression amounts generated by the first elastic member 4 to adjust and control the spacing between the stripping blades 32.

[0024] The embodiment of the utility model provides an adjusting member 5 for moving in the gap 12 between the movable block 34 and the bottom wall of the installation cavity 10 to apply different thrusts to the first elastic member 4 that elastically connects the two groups of wire stripping assemblies 3. The first elastic member 4 contracts accordingly under the thrust to produce different elastic compression amounts, thereby changing the opening and closing size between the wire stripping blades 32 to adapt to wires of different diameters. In the specific implementation process, the adjusting member 5 can be a wedge-shaped member that is wide at the top and narrow at the bottom. The end close to the wire stripping blade 32 has a large thrust on the first elastic member 4, thereby reducing the spacing between the wire stripping blades 32, while the end away from the wire stripping blade 32 has a small thrust on the first elastic member 4, thereby increasing the spacing between the wire stripping blades 32.

[0025] In another optional embodiment of the present invention, Figure 1-Figure 2 and Figure 4-Figure 5As shown, a positioning block 6 for limiting the minimum spacing of the stripping blades 32 is also provided between the two sets of blade holders 30 of the stripping assemblies 3. In this embodiment, the positioning block 6 is provided between the two sets of blade holders 30 of the stripping assemblies 3 to limit the minimum spacing of the stripping blades 32 during the shearing operation, thereby avoiding excessive shearing of the wires and damaging the wire cores. In specific implementation, the distance between the positioning block 6 and the wire stripping blade 32 on the tool holder 30 can be adjusted according to the diameter data of the wire core. The larger the diameter of the wire core, the farther the positioning block 6 moves from the wire stripping blade 32, and the smaller the diameter of the wire core, the closer the positioning block 6 moves to the wire stripping blade 32. The spacing between the wire stripping blades 32 is adjusted by the adjusting member 5 to match the diameter of the wire. Half of the difference between the spacing between the wire stripping blades 32 and the minimum spacing defined by the positioning block 6 is the thickness of the insulation layer. In this way, the cutting depth of the wire stripping pliers can be flexibly adjusted, which can ensure that the insulation layer is completely cut off while the wire core is completely retained. The insulation layer can be completely stripped with one knife. The operation is quick and convenient, and the wire stripping efficiency is high.

[0026] In another optional embodiment of the present invention, Figure 5 As shown, the slit 12 is a wedge-shaped slit 12 that is narrow at one end close to the stripping blade 32 and wide at one end away from the stripping blade 32. When the adjusting member 5 moves toward the end close to the stripping blade 32, the elastic compression amount of the first elastic member 4 increases, thereby closing the distance between the two stripping blades 32. In this embodiment, by setting the slit 12 to be a wedge-shaped slit 12 that is narrow at one end close to the stripping blade 32 and wide at one end away from the stripping blade 32, the adjusting member 5 exerts a small pressure on the first elastic member 4 at the wide end of the slit 12, so the distance between the stripping blades 32 is relatively large, and can adapt to thicker wires, while the pressure on the first elastic member 4 at the narrow end is large, so the distance between the stripping blades 32 is relatively small, and can adapt to thinner wires.

[0027] In another optional embodiment of the present invention, Figure 2 , Figure 4 and Figure 5 As shown, the adjusting member 5 includes a cushion block 50 arranged to fit the movable block 34 and an adjusting buckle 52 slidably connected to the cushion block 50. A slide groove 501 is provided on the side of the cushion block 50 away from the movable block 34. A slider 521 protrudes from the adjusting buckle 52 corresponding to the slide groove 501. The adjusting buckle 52 is slidably connected to the cushion block 50 by being embedded in the slide groove 501 with the slider 521. The adjusting buckle 52 in this embodiment includes a cushion block 50 and an adjusting buckle 52. One side of the cushion block 50 fits the movable block 34 and the opposite side has a slide groove 501 for sliding connection of the adjusting buckle 52. The structure is simple and the assembly is convenient.

In this embodiment, the operating portion 523 is formed protruding from one end of the adjusting buckle 52, and the adjusting hole 14 is provided on the side wall of the installation cavity 10 for exposing the operating portion 523, so as to facilitate the user's adjustment operation. At the same time, the two ends of the adjusting hole 14 can also be used to limit the adjustment range of the adjusting member 5, so as to avoid excessive adjustment and cause the adjusting buckle 52 to fall out relative to the cushion block 50.

[0029] In another optional embodiment of the present invention, Figure 3-Figure 4 As shown, a tooth 525 is formed in the middle of the adjustment buckle 52, and a rack 16 is provided on the side wall of the installation cavity 10 corresponding to the tooth 525. The adjustment buckle 52 is relatively fixed in position by snapping the tooth 525 into the corresponding tooth groove on the rack 16. In this embodiment, the tooth 525 is provided in the middle of the adjustment buckle 52, and the rack 16 is provided on the side wall of the installation cavity 10 correspondingly. The adjustment buckle 52 is relatively fixed by snapping the tooth 525 into the rack 16, and the adjustment buckle 52 is pushed to make the tooth 525 mesh and move on the rack 16 to adjust the depth of the wire cutting of the wire stripping blade 32, thereby improving the adjustment accuracy.

[0032] In another optional embodiment of the present invention, Figure 2 as well as Figure 4-Figure 6 As shown, a handle 15 extends from the end of the first pliers body 1a to the second pliers body 1b, and the second pliers body 1b is correspondingly embedded in the first pliers body 1a and forms a U-shaped groove 18 at the end. One end of the connecting rod 20 is hinged to the third pliers body 2 and the opposite end is hinged to the roller 25 through the third pivot 23. The connecting rod 20 is abutted and connected with the second pliers body 1b with the roller 25 embedded in the U-shaped groove 18. The third pliers body 2 is pressed so that the connecting rod 20 pushes the third pivot 23 to move along the extension direction of the connecting rod 20, thereby causing the roller 25 to push the second pliers body 1b to pivot around the first pivot 1c in the direction away from the third pliers body 2, and the end of the second pliers body 1b away from the U-shaped groove 18 pivots and engages in the direction close to the first pliers body 1a. In this embodiment, one end of the connecting rod 20 is hinged to the third pliers body 2 and the other end is hinged to the roller 25 through the third pivot 23, and the roller 25 is embedded in the U-shaped notch 18 at the end of the second pliers body 1b and relatively abuts against it.
