[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0023] like Figure 1-5As shown, the utility model provides a cable insulation layer ring cutting machine, comprising a ring 1, a ring cutting knife 3 is arranged inside the ring 1, the ring cutting knife 3 is used to cut the cable, and a cutting mechanism is arranged inside the ring 1, the cutting mechanism is used to cut the cable insulation layer;

[0024] The cutting mechanism includes a support rod 4 rotatably connected to the inner wall of the circular ring 1, a rectangular groove 8 is provided inside the support rod 4, and a slide groove 9 is provided at the front and rear positions of the support rod 4 located at the rectangular groove 8, a slider 11 is slidably connected inside the slide groove 9, and the slider 11 can move inside the slide groove 9, and a first spring 10 is fixedly connected to one side of the slider 11, and the first spring 10 has a certain driving force on the slider 11, and the opposite sides of the two sliders 11 are rotatably connected with a ring cutter 3, and the ring cutter 3 can cut the cable through the thrust of the first spring 10, and the rear end of the circular ring 1 is rotated. The rotating block 2 is dynamically connected, and rectangular openings 12 are evenly opened at the front end of the rotating block 2. The rectangular opening 12 is slidably connected to the side wall of the support rod 4. The rotating block 2 is rotated to make the rotating block 2 and the ring 1 move relative to each other. The front end of the rotating block 2 is provided with a raised round block, and extends to the inside of the ring 1. The length of the rectangular groove 8 is greater than the diameter of the ring cutter 3. The outer side of the support rod 4 fits with the inner wall of the rectangular groove 8. The outer side of the ring 1 and the outer side of the rotating block 2 are both provided with anti-skid pads. The anti-skid pads can increase the friction and provide better stability when holding the ring 1 and the rotating block 2.

[0025] When working, the cable that needs to be circumcised is passed through the ring 1, and the entire assembly is moved to the place where the cable needs to be cut. At this time, the ring 1 is held in one hand, and the rotating block 2 is rotated with the other hand. At this time, the rotating block 2 rotates to drive the rectangular opening 12 to rotate. It should be noted that the initial state of the support rod 4 is tilted, so that the ring 1 will not be blocked by the support rod 4 when it passes through the cable. The rotating block 2 is rotated under the action of the rectangular opening 12, so that the support rod 4 rotates, and one end of the support rod 4 is attached to the outside of the cable. At this time, the ring cutter 3, under the action of the cable, makes the slider 11 move inside the slide groove 9 and compress the first spring 10 at the same time. At this time, the ring 1 and the rotating block 2 are rotated at the same time, so that the ring cutter 3 rotates around the cable. At this time, under the action of the first spring 10, the ring cutter 3 continuously extends into the cable, thereby realizing the ring cutting of the insulating layer. Such operation is relatively simple, and the ring cutting of the insulating layer is relatively smooth, and there will be no skew, thereby improving the ring cutting effect. Through this device, the cutting effect can be well achieved for cables of different diameters, thereby improving the applicability of the device.

[0026] like Figure 1-5As shown, the front end of the support rod 4 is fixedly connected to the rotating rod 6, the inner wall of the ring 1 is located at the front end of the support rod 4 and is fixedly connected to a fixed block 5, the inner wall of the fixed block 5 is fixedly connected to a return spring 7, and the return spring 7 is fixedly connected to the rod wall of the rotating rod 6. When the support rod 4 rotates, the return spring 7 will be deformed, so that when the ring cutting work is completed, the support rod 4 can be reset under the action of the return spring 7 to facilitate the next ring cutting work.

[0027] Working principle: pass the cable that needs to be ring-cut through the ring 1, and move the entire assembly to the place where the cable needs to be cut. At this time, hold the ring 1 with one hand and rotate the rotating block 2 with the other hand. At this time, the rotation of the rotating block 2 drives the rectangular opening 12 to rotate. It should be noted here that the initial state of the support rod 4 is tilted, so that the ring 1 will not be blocked by the support rod 4 when it passes through the cable. The rotating block 2 is rotated under the action of the rectangular opening 12 to make the support rod 4 rotate, and one end of the support rod 4 is attached to the outside of the cable. At this time, the ring cutter 3, under the action of the cable line, makes the slider 11 move inside the slide groove 9 and compress the first spring 10 at the same time. At this time, the ring 1 and the rotating block 2 are rotated at the same time, so that the ring cutter 3 rotates around the cable line. At this time, under the action of the first spring 10, the ring cutter 3 continuously extends into the cable, thereby realizing the ring cutting of the insulation layer. Such operation is relatively simple, and the ring cutting of the insulation layer is relatively smooth, and there will be no skew, thereby improving the ring cutting effect.
