Description

Technical Field

[0001] This utility model belongs to the technical field of wire stripping tools, and more specifically, it relates to a blade adjustment mechanism and wire strippers. Background Technology

[0002] Wire strippers are primarily used to remove the insulation layer of cables. They work by squeezing two operating handles to hold the cable between the clamps. Further squeezing causes the blades on the clamps to cut through the cable's insulation. Pulling / activating the handles then separates the insulation from the conductor, completing the stripping operation. In existing technology, because the two blades used to clamp the cable are in a relatively fixed position, it is difficult to control the squeezing force and cutting depth for cables of different thicknesses. This can easily cut the cable core, resulting in reduced stripping efficiency and cable waste. Utility Model Content

[0003] The purpose of this utility model is to provide a blade adjustment structure and wire stripper to solve the technical problems in the prior art where the two blades used for clamping the wire are in relatively fixed positions, making it difficult to control the squeezing force and cutting depth for cables of different thicknesses, easily cutting off the wire core, resulting in reduced wire stripping efficiency and cable waste.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A blade adjustment mechanism is provided, which is mounted on the clamp of a wire stripper and connected to a blade used for cutting cables. The blade adjustment mechanism includes a blade holder, an adjusting screw, and an adjusting nut. The blade holder has a first end and a second end, the first end and the second end being opposite to each other. The end of the blade opposite to the cutting edge is embedded in the first end. One end of the adjusting screw is fixedly connected to the second end. The adjusting nut is sleeved on the adjusting screw and threadedly connected to it. The blade holder is circumferentially limited within the clamp, and the adjusting nut is axially limited within the clamp and can be rotated and adjusted relative to the clamp.

[0005] Furthermore, the clamp has a insertion cavity and a through cavity for the blade to pass through, the through cavity communicating with the insertion cavity, and the blade holder is inserted into the insertion cavity and circumferentially limited within the insertion cavity.

[0006] Optionally, the cross-sectional outer contour of the tool holder is elliptical, polygonal, or D-shaped. The tool holder is adapted to the insertion cavity and can be moved in the insertion cavity along the axis of the adjusting screw by the adjusting screw.

[0007] As an alternative, the tool holder has a protrusion on its side and the clamp has a groove in the cavity wall of its insertion cavity; or, the clamp has a protrusion in the cavity wall of its insertion cavity and the tool holder has a groove on its side; the tool holder is adapted to the insertion cavity, the protrusion is inserted into the groove and is driven by the adjusting screw to move along the axis of the adjusting screw.

[0008] Furthermore, the blade adjustment mechanism also includes a limiting pin, the end of the adjusting screw is inserted into the second end of the tool holder, and the limiting pin is transversely inserted through the tool holder and the adjusting screw located in the second end.

[0009] Furthermore, the adjusting nut includes a limiting part and an adjusting part connected to one end of the limiting part. The limiting part is axially limited within the insertion cavity, and the adjusting nut is located at the opening of the insertion cavity.

[0010] Furthermore, the blade adjustment mechanism also includes at least one pin, the limiting part has an annular locking groove on its periphery, the clamp has at least one pin hole communicating with the insertion cavity, and the pin is transversely inserted into the pin hole of the clamp and the annular locking groove of the limiting part.

[0011] Preferably, the clamp has an arc-shaped positioning groove on the wall of its insertion cavity that matches the shape of the limiting part, the limiting part can rotate freely in the arc-shaped positioning groove, and the pin hole communicates with the arc-shaped positioning groove.

[0012] Preferably, the clamp has an annular positioning groove on the outer edge of the insertion cavity opening in the direction of the cavity, the annular positioning groove is connected to the insertion cavity, and the pin can pass laterally through the pin hole and the annular locking groove when the adjustment part abuts against the bottom of the annular positioning groove.

[0013] This utility model also provides a wire stripper, which includes the aforementioned blade adjustment mechanism.

[0014] The beneficial effects of the blade adjustment mechanism and wire stripper provided by this utility model are as follows: The blade adjustment mechanism is installed on the clamp of the wire stripper, and the blade connected to it cooperates with another blade on the wire stripper to strip the insulation layer on the cable. The blade adjustment mechanism includes a blade holder, an adjusting screw, and an adjusting nut. The blade holder has a first end and a second end, which are opposite to each other. The end of the blade opposite to the cutting edge is embedded in the first end. One end of the adjusting screw is fixedly connected to the second end. The adjusting nut is sleeved on the adjusting screw and threadedly connected to the adjusting screw. The blade holder is circumferentially limited in the clamp, and the adjusting nut is axially limited in the clamp and can be rotated and adjusted relative to the clamp. In this way, the blade holder cannot rotate relative to the clamp; it can only move along the axis of the adjusting screw under the drive of the adjusting screw. The adjusting nut is threadedly connected to the adjusting screw and cannot move along the axis of the adjusting screw, but it can rotate freely. When the adjusting nut rotates clockwise or counterclockwise, the adjusting screw moves along the axis relative to the axially limited adjusting nut, which in turn moves the blade holder and the blade together, realizing the adjustment of the blade height. For cables of different thicknesses, the distance between the two blades can be adjusted, which makes it easier to control the squeezing force and cutting depth, ensure the integrity of the cable core, improve stripping efficiency, and reduce cable loss.

[0027] Please refer to the following as well. Figures 1 to 4 This utility model embodiment provides a blade adjustment mechanism 100, which is mounted on the clamp 200 of a wire stripper 1 and connected to a blade 300 used for cutting cables. The blade adjustment mechanism 100 includes a blade holder 110, an adjusting screw 120, and an adjusting nut 130. The blade holder 110 has a first end 111 and a second end 112, with the first end 111 and the second end 112 facing away from each other. The end of the blade 300 facing away from the cutting edge is embedded in the first end 111. One end of the adjusting screw 120 is fixedly connected to the second end 112. The adjusting nut 130 is sleeved on the adjusting screw 120 and threadedly connected to it. The blade holder 110 is circumferentially limited to the clamp 200, meaning the blade holder 110 cannot rotate relative to the clamp 200. The adjusting nut 130 is axially limited to the clamp 200 and can rotate relative to the clamp 200 for adjustment, meaning the adjusting nut 130 cannot move along the axial direction of the adjusting screw 120.

[0028] In this embodiment, the blade adjustment mechanism 100 is mounted on the clamp 200 of the wire stripper 1. The blade 300 connected to it cooperates with another blade on the wire stripper 1 to strip the insulation layer on the cable. The blade adjustment mechanism 100 includes a blade holder 110, an adjusting screw 120, and an adjusting nut 130. The blade holder 110 has a first end 111 and a second end 112, with the first end 111 and the second end 112 facing away from each other. The end of the blade 300 facing away from the cutting edge is embedded in the first end 111. One end of the adjusting screw 120 is fixedly connected to the second end 112. The adjusting nut 130 is sleeved on the adjusting screw 120 and threadedly connected to the adjusting screw 120. The blade holder 110 is circumferentially limited to the clamp 200, and the adjusting nut 130 is axially limited to the clamp 200 and can be rotated and adjusted relative to the clamp 200. In this way, the blade holder 110 cannot rotate relative to the clamp 200, but can only move along the axis of the adjusting screw 120 under the drive of the adjusting screw 120. The adjusting nut 130 is threadedly connected to the adjusting screw 120 and cannot move along the axis of the adjusting screw 120, but can rotate freely. When the adjusting nut 130 rotates clockwise or counterclockwise, the adjusting screw 120 moves along the axis relative to the axially limited adjusting nut 130, and drives the blade holder 110 and the blade 300 to move together, realizing the lifting and lowering adjustment of the blade 300. For cables of different thicknesses, the distance between the two blades can be adjusted, which makes it easier to control the squeezing force and cutting depth, ensure the integrity of the cable core, improve the stripping efficiency, and reduce cable loss.

[0029] Furthermore, the clamp 200 is provided with a insertion cavity 201 and a through cavity 202 for the blade 300 to pass through. The through cavity 202 communicates with the insertion cavity 201. The blade holder 110 is inserted into the insertion cavity 201 and circumferentially limited within the insertion cavity 201. The blade holder 110 is circumferentially limited within the insertion cavity 201 and cannot rotate relative to the insertion cavity 201, ensuring that the blade 300 can be adjusted for height. The blade 300 passes through the insertion cavity 201 and the through cavity 202 in sequence, with the cutting edge protruding from the through cavity 202.

[0030] Optionally, the cross-sectional outer contour of the tool holder 110 is elliptical, polygonal, or D-shaped. The tool holder 110 is adapted to the insertion cavity 201 and can be moved in the insertion cavity 201 along the axis of the adjusting screw 120 by the adjusting screw 120.

[0031] As an alternative, the tool holder 110 has a protrusion on its side, and the clamp 200 has a groove in the cavity wall of its insertion cavity 201. Alternatively, the clamp 200 has a protrusion in the cavity wall of its insertion cavity 201, and the tool holder 110 has a groove on its side. The tool holder 110 is adapted to the insertion cavity 201, the protrusion is inserted into the groove, and is driven by the adjusting screw 120 to move along the axial direction of the adjusting screw 120.

[0032] The above solutions all achieve the goal of limiting the rotation of the tool holder 110 through the insertion cavity 201, and also satisfy the directional installation of the tool holder 110. In this embodiment, the outer contour of the cross-section of the tool holder 110 is rectangular. There are no excessive restrictions here, as long as the tool holder 110 can move axially without rotating circumferentially.

[0033] Furthermore, the blade adjustment mechanism 100 also includes a limiting pin 140. The end of the adjusting screw 120 is inserted into the second end 112 of the tool holder 110, and the limiting pin 140 is laterally inserted through the tool holder 110 and the adjusting screw 120 located in the second end 112. In this embodiment, the adjusting screw 120 and the second end 112 of the tool holder 110 can be threaded, clearance-fitted, or interference-fitted. By the limiting pin 140 laterally inserting through the tool holder 110 and the adjusting screw 120 located in the second end 112, the inserted end of the adjusting screw 120 is locked onto the tool holder 110, thereby achieving a fixed connection between the tool holder 110 and the adjusting screw 120.

[0034] Furthermore, the adjusting nut 130 includes a limiting part 131 and an adjusting part 132 connected to one end of the limiting part 131. The limiting part 131 is axially limited within the insertion cavity 201, and the adjusting nut 130 is located at the cavity opening 203 of the insertion cavity 201, outside the clamp 200, and can be manually rotated.

[0035] Furthermore, the blade adjustment mechanism 100 also includes at least one pin 150, and the limiting part 131 has an annular locking groove 101 on its periphery. The clamp 200 has at least one pin hole 204 communicating with the insertion cavity 201. The pin 150 is laterally inserted into the pin hole 204 of the clamp 200 and the annular locking groove 101 of the limiting part 131. In this embodiment, the pin 150 passes tangentially through the annular locking groove 101 of the limiting part 131.

[0036] In this embodiment, both the limiting part 131 and the adjusting part 132 are fitted onto the adjusting screw 120. At least one of the adjusting part 132 and the limiting part 131 is threadedly connected to the adjusting screw 120. The side of the limiting part 131 engages with the pin 150 through an annular locking groove 101, achieving axial limiting, meaning it cannot move along the axis of the adjusting screw 120, but can rotate freely. Because the side of the limiting part 131 is provided with an annular locking groove 101, the limiting part 131 and the pin 150 always remain axially locked, no matter where the adjusting part 132 rotates to. This forces the adjusting screw 120 to move along the axis, ultimately achieving the lifting and lowering adjustment of the blade 300.

[0037] Preferably, the clamp 200 has an arc-shaped positioning groove 205 in the cavity wall of its insertion cavity 201, which is adapted to the shape of the limiting part 131. The limiting part 131 can rotate freely in the arc-shaped positioning groove 205, and the pin hole 204 communicates with the arc-shaped positioning groove 205. In this way, the directional insertion of the adjusting nut 130 is satisfied, and at the same time, it also helps to improve the stability of the adjusting nut 130.

[0038] Preferably, the clamp 200 has an annular positioning groove 206 on the outer edge of the cavity opening 203 of the insertion cavity 201 towards the through cavity 202. The annular positioning groove 206 communicates with the insertion cavity 201. When the adjusting part 132 abuts against the bottom of the annular positioning groove 206, the pin 150 can pass laterally through the pin hole 204 and the annular locking groove 101. At this time, when the adjusting part 132 abuts against the bottom of the annular positioning groove 206, the pin hole 204 is directly opposite to and communicates with the annular locking groove 101, which facilitates the positioning and insertion of the pin 150.

[0039] Preferably, there are two pins 150, and the number of arc-shaped positioning grooves 205 corresponds one-to-one with the number of pins 150. This helps to improve the overall stability of the adjusting nut 130.

[0040] Please see Figure 1 This utility model embodiment also provides a wire stripper 1, which includes the blade adjustment mechanism 100 described above.

[0041] In this embodiment, the blade adjustment mechanism 100 is mounted on the clamp 200 of the wire stripper 1 and is fixedly connected to the blade 300. It can drive the blade 300 to rise and fall for adjustment. For cables of different thicknesses, the distance between the two blades can be adjusted to facilitate control of the squeezing force and cutting depth, ensure the integrity of the cable core, improve stripping efficiency, and reduce cable loss.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
