In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] like Figure 1-Figure 6 As shown, a rotary cutting type wire stripper provided in this embodiment includes: a first handle 1; a second handle 6; a first clamping block 2, the first clamping block 2 and one end of the first handle 1 are fixedly connected; a second clamping block 4, the second clamping block 4 and one end of the second handle 6 are fixedly connected; a blade 10, the blade 10 is movably connected to the second clamping block 4, the blade 10 can adjust the angle relative to the clamped cable, and the blade 10 can also adjust the depth of feeding the clamped cable; a connecting rod 3, one end of the connecting rod 3 is fixedly connected to the first clamping block 2, and the other end of the connecting rod 3 passes through the second clamping block 4 and is slidably connected to the second handle 6; a first locking member 5, the first locking member 5 can lock the connecting rod 3 and the second clamping block 4. In this embodiment, the first handle 1 and the second handle 6 can both be existing grip handles, and the construction personnel can rotate any one of the handles around the cable to a certain angle, and the other handle can be rotated to a position convenient for the construction personnel to hold, and the cable insulation layer can be cut off through circular rotation. The first clamp block 2 and the second clamp block 4 can both be existing clamping structures for clamping cables. The cables are clamped by controlling the first clamp block 2 and the second clamp block 4 to approach each other, and the cables are released by moving the first clamp block 2 and the second clamp block 4 away from each other. The blade 10 is a blade 10 used in existing cable strippers, which can be connected to the second clamp block 4 through a movable part, so that after the second clamp block 4 and the second clamp block 4 clamp the cable, the blade 10 contacts the insulation layer of the cable, and the first handle 1 or the second handle 6 is controlled to make the entire stripper rotate along the cable, and the blade 10 cuts the insulation layer of the cable. The angle of the blade 10 relative to the plane of the second clamp block 4 clamping the cable and the feed depth are adjusted, so that the cable can be stripped accurately and quickly.

[0032] The blade 10 is slidably connected with the second clamping block 4 through the first adjusting member 7, and the first adjusting member 7 can drive the blade 10 to slide in the direction of the first clamping block 2. The second clamping block 4 is provided with a through hole, and the extension direction of the through hole is parallel to the extension direction of the connecting rod 3. One end of the first adjusting member 7 extends from the through hole toward the first clamping block 2, and the blade 10 is connected to one end of the first adjusting member 7. Specifically, the first adjusting member 7 can be a rod, and the first adjusting member 7 can be fixed to the second clamping block 4 by abutting with a screw. After adjusting the position where the first adjusting member 7 drives the blade 10 to extend toward the first clamping block 2, the screw passes through the base frame clamping block to extend to the through hole, and the screw abuts with the first adjusting member 7 to fix the first adjusting member 7, so as to determine the thickness of the cable cut by the blade 10. In addition, the first adjusting member 7 can also be a combination of a rod with a threaded section and a sleeve, the through hole is provided with an internal thread, the threaded section cooperates with the internal thread, and the sleeve is rotatably connected to the rod by rotating the threaded rod, so that the sleeve does not rotate with the rotation of the rod, and only the sleeve is pushed by the rod to drive the blade to move toward the first clamping block, and the scale rod is connected to the sleeve, so that the feed depth can be observed. In addition, the sleeve and the through hole are interference fit, so that the sleeve is not easily driven to rotate by external force, that is, when the blade is stripping the wire, the sleeve will not rotate due to the reaction force, causing the angle of the blade to deflect.

[0033] The blade 10 is connected to one end of the first adjusting member 7 through the second adjusting member 11. The first adjusting member 7 is provided with a first threaded hole. The second adjusting member 11 is threadedly connected to the first threaded hole. One end of the second adjusting member 11 passes through the first adjusting member 7 and is fixedly connected to the blade 10. Specifically, the second adjusting member 11 can be a screw. The blade 10 is fixedly sleeved on the outside of the second adjusting member 11. By rotating the second adjusting member 11, the opening of the blade 10 and the angle relative to the second clamping block 4 are adjusted.

[0034] The second clamping block is provided with a limit hole 12, the edge of the limit hole is provided with a scale 13, the limit hole is connected to the through hole, a scale rod 14 is slidably connected in the limit hole, and the scale rod is fixedly connected to the first adjusting member. Specifically, the extension direction of the limit hole is consistent with the extension direction of the connecting rod, so that the feeding depth of the blade 10 can be obtained, and the depth of the blade 10 cutting into the insulating layer can be accurately grasped.

[0035] The surfaces of the first clamping block 2 and the second clamping block 4 facing each other are both provided with a V-shaped groove 9 or an arc groove. By providing the V-shaped groove 9 or the arc groove, and the first clamping block 2 and the second clamping block 4 can move relative to each other, so that cables of different specifications can be clamped, and the V-shaped groove 9 or the arc groove can ensure the stability of clamping the cable.

[0036] The second clamping block 4 is provided with a weight-reducing groove 8. By providing the weight-reducing groove 8, the overall weight is reduced, and the fatigue degree of the construction workers is reduced.

[0037] The second clamping block 4 is provided with a second threaded hole and a movable hole, the second threaded hole is connected with the movable hole, the other end of the connecting rod 3 passes through the movable hole and is slidably connected with the second handle 6, the first locking member 5 is threadedly connected with the second threaded hole, and the end of the first locking member 5 abuts against the connecting rod 3. Specifically, the first locking member 5 can be a screw or a stop handwheel, the second handle 6 is hollow inside, one end of the second handle 6 connected to the second clamping block 4 is provided with an opening connected to the inside, the movable hole is butted against the opening, and when the connecting rod 3 passes through the movable hole, it is inserted from the opening into the inside of the second handle 6, so as to adjust the distance between the first clamping block 2 and the second clamping block 4.

[0038] The cross section of the connecting rod 3 is rectangular. By setting the cross section of the connecting rod 3 to be rectangular, when the first clamping block 2 and the second clamping block 4 move relative to each other, the two will not rotate relative to each other, and the opposite surfaces of the first clamping block 2 and the second clamping block 4 are kept opposite to each other, ensuring that the first clamping block 2 and the second clamping block 4 can clamp and fix the cable.

[0039] The gripping parts of the first handle 1 and the second handle 6 are truncated cone structures. By setting the gripping parts of the first handle 1 and the second handle 6 as truncated cone structures, it is convenient for construction workers to hold them.

[0040] The rotary cutting wire stripper provided in this embodiment is mainly used for stripping the main insulation layer of the cable, the outer semi-conductive layer of the cable, the shielding layer of the cable, the insulated wire stripping, etc.

[0041] The application process of the rotary cutting wire stripper provided in this embodiment is as follows:

[0042] 1. Wire clamping: Loosen the first locking piece 5, pull the first handle 1 and the second handle 6 to move the first clamping block 2 and the second clamping block 4 away from each other, put the cable into the V-shaped groove 9 of the first clamping block 2, place the end of the cable to be stripped flush with the blade 10, move the second clamping block 4 to clamp (moderately), and lock the first locking piece 5 so that the cable is clamped between the first clamping block and the second clamping block.

[0043] 2. Adjust the blade: first adjust the first adjusting member 7 so that the tip of the blade 10 is placed on the plane of the cable sheath and the core, and then rotate the second adjusting member to tilt the blade 10.

[0044] 3. Stripping: Turn the first handle 1 or the second handle 6, and the rotary-cutting wire stripper can then spin the cable wrapping into a spiral strip. Turn the first handle 1 or the second handle 6 one more circle to cut the stripped spiral strip in a circular shape, and the stripping is complete.

[0045] Precautions

[0046] 1. When clamping the cable, the clamping force should be moderate, that is, the rotary cutting wire stripper can rotate around the cable without shaking. If it is too tight, it will not rotate, and if it is too loose, it will shake and easily damage the blade 10.

[0047] 2. The knife must reach the interface between the cable sheath and the wire core. If it is too shallow, the knife cannot cut through and the bare wire end cannot be stripped. If it is too deep, the wire core will be damaged and the knife tip will easily break.

[0048] 3. To protect the blade tip, retract the blade 10 into the weight-reducing groove 8 when not in use.

[0049] 4. The second adjusting member 11 for adjusting the knife tilt should be loosened before adjustment and locked after adjustment; the first locking member 5 on the second clamping block 4 should be locked during operation and storage.

[0050] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
