The through hole 41 is symmetrically provided inside the upper housing 1 and the lower housing 2. The wire stripping mechanism 4 can strip the insulation layer of the wire. The bottom of the upper housing 1 and the top of the lower housing 2 are symmetrically provided with wire clamping ports 5. The wire clamping ports 5 can restrict the position of the wire.
[0034] refer to Figure 1 and Figure 2 The front of the limiting block 301 is provided with a first groove 302, and a first slider 303 slides on the inner wall of the first groove 302. A control rod 304 is fixedly connected to the right side of the first slider 303. The control rod 304 can control the position of the first slider 303, making it convenient for the operator to open and close the upper shell 1 and the lower shell 2. The first slider 303 is set in a trapezoidal shape. When the limiting block 301 moves downward, the first slider 303 will be pressed by the limiting block 301 due to its trapezoidal shape, causing the first slider 303 to slide. The inner wall of the notch of the lower shell 2 is provided with a first groove 306. A first spring 305 is fixedly connected to the front of the first slider 303. The front of the first spring 305 is fixedly connected to the inner wall of the first groove 306. The combination of the first groove 306 and the first spring 305 can control the position of the first slider 303.
[0035] refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The cutting assembly 6 includes a rotating rod 602, the top of which is fixedly connected to the top of the upper handle 401. The rotating rod 602 is rotatably connected inside the through hole 41. A second slider 606 is fixedly connected to the outside of the rotating rod 602. A second spring 607 is fixedly connected to the inner wall of the second slider 606. A ball bearing 608 is fixedly connected to the left side of the second spring 607. The second slider 606 slides on the inner wall of the second groove 42. When the handle 40 is rotated, the rotating rod 602 also rotates. At this time, the second slider 606 slides on the inner wall of the second groove 42, and the ball bearing 608 is compressed, thereby compressing the second spring 607. When the ball bearing 608 moves to the position of the second groove 421, the elastic return of the second spring 607 fits against the second groove 421, limiting the position of the handle 40. A threaded rod 601 is threadedly connected inside the rotating rod 602. A connecting block 604 is rotatably connected to the bottom of 01. A sleeve 603 is slidably connected to the outside of the connecting block 604. A third groove 610 is provided on the inner wall of the sleeve 603. A third slider 609 is slidably connected to the inner wall of the third groove 610. The third slider 609 is fixedly connected to the outside of the connecting block 604. The top of the sleeve 603 is fixedly connected to the bottom of the rotating rod 602. A blade 605 is provided at the bottom of the connecting block 604. The blade 605 has an arc-shaped cut. The rotatable connection between the threaded rod 601 and the connecting block 604 can control the up and down position of the connecting block 604, preventing the blade 605 from directly cutting into the insulation layer and hindering the adjustment of the angle of the blade 605. The combination of the third groove 610 and the third slider 609 in the sleeve 603 can prevent the connecting block 604 from rotating arbitrarily when moving up and down. The blade 605 with the arc-shaped cut can perform a circumferential cut on the insulation layer of the wire, making the cut smooth.
[0036] Working principle: In use, the operator first rotates the handle 40 to a position perpendicular to the housing. When rotating the handle 40, the ball 608 on the second slider 606 is squeezed by the inner wall of the second groove 42, compressing the second spring 607. When the ball 608 rotates to the position of the second groove 421, the elastic return of the second spring 607 causes the ball 608 to fit against the second groove 421, thus limiting the position of the handle 40. However, this limitation is not fixed. At this time, the control lever 304 is pushed forward to drive the first slider 303 to compress the first spring 305. After the first slider 303 slides out of the first groove 302, the upper housing 1 is rotated upward. At this time, the wire can be placed at the wire clamping port 5. Rotating the threaded rod 601 changes the up and down position of the blade 605. At this time, the third slider 609 outside the connecting block 604 is in the sleeve. The blade 605 slides within the third groove 610 on the inner wall of the cylinder 603 to prevent it from directly cutting into the insulation layer of the wire. The upper housing 1 and the lower housing 2 are closed. At this time, the limiting block 301 presses the inclined surface of the first slider 303, causing the first slider 303 to slide within the inner wall of the first groove 306. When the first groove 302 moves to the position of the first slider 303, the elastic return of the first spring 305 causes the first slider 303 to fit against the first groove 302. At this time, the operator can rotate the handle 40 according to the required wire length and cut shape. When the handle 40 drives the blade 605 to rotate to a suitable angle, the threaded rod 601 can be rotated to change the up and down position of the blade 605, allowing the blade 605 to cut into the insulation layer of the wire. At this time, the operator can move or rotate the entire device to strip the insulation layer of the wire.
[0037] After the wire stripping work is completed, rotate the threaded rod 601 to adjust the upper and lower positions of the blade 605, then rotate the handle 40 to make it perpendicular to the housing. Move the control rod 304 forward to drive the first slider 303 to compress the first spring 305. When the first slider 303 slides out of the first groove 302, rotate the upper housing 1 upward to remove the wire, then close the upper housing 1 and the lower housing 2 to complete the work.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
