Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 4The utility model provides an embodiment of a wire and cable detection measuring tool, including a base 1, a support frame 2 is fixedly connected to the top of the base 1, a rotating shaft 3 is rotatably connected to the inner wall of the support frame 2, a push rod 4 is rotatably connected to the inner wall of the rotating shaft 3, a slider 5 is fixedly connected to the outer wall of the push rod 4, a slide groove 6 is provided on the inner wall of the rotating shaft 3, and the outer wall of the slider 5 is slidably connected to the inner wall of the slide groove 6. When the rotating shaft 3 rotates, the slider 5 will slide along the slide groove 6, so that the push rod 4 moves slowly to the outside, and a gear 9 is rotatably connected to the inner wall axis of the base 1. Two groups of inner racks 8 are slidably connected to the inner wall of the base 1. The inner walls of the two groups of inner racks 8 are meshed with the outer wall of the gear 9. When the position of one group of inner racks 8 changes, the gear 9 will be driven to rotate, so that the gear 9 drives the position of the other group of inner racks 8 to change. The tops of the two groups of inner racks 8 are fixedly connected with clamping blocks 7. The two groups of inner racks 8 will move closer to each other under the action of the gear 9 to fix the cable, and the back of one group of clamping blocks 7 is connected to the end of the push rod 4 The push rod 4 drives the clamping block 7 to move toward the center. The inner wall of the rotating shaft 3 is elastically connected with the pull rod a11 through the reset spring a10. The outer wall of the pull rod a11 is provided with a rectangular protrusion structure. After being pulled out, the rotating shaft 3 can be driven to rotate together. One end of the reset spring a10 is fixedly connected to the end of the pull rod a11, and the other end of the reset spring a10 is fixedly connected to the inner wall of the rotating shaft 3. Pulling the pull rod a11 outward will stretch the reset spring a10 to move outward. At the same time, the reset spring The elastic force generated by the deformation of spring a10 gives an inward pulling force to the pull rod a11, prompting it to reset. The inner wall of the pull rod a11 is fixedly connected to the limiting assembly, and the limiting assembly includes a limiting block 12. The inner wall of the pull rod a11 is fixedly connected to the back of the limiting block 12. A limiting groove 13 is provided on the back of the support frame 2. The inner wall of the limiting groove 13 is clamped with the outer wall of the limiting block 12. Pulling the pull rod a11 outward can make the limiting block 12 withdrawn from the limiting groove 13, and the pull rod a11 can be rotated at this time.

[0032] Reference Figure 1 The outer wall of the base 1 is fixedly connected with a frame 16, and the inner wall of the frame 16 is elastically connected with a splint 18 through a return spring b20. One end of the return spring b20 is fixedly connected to the inner wall of the frame 16, and the other end of the return spring b20 is fixedly connected to the top of the splint 18. The splint 18 can squeeze the return spring b20 to move upward. At the same time, the elastic force generated by the deformation of the return spring b20 gives the splint 18 a thrust in the opposite direction, prompting it to reset. The inner wall of the frame 16 is slidably connected with a pull rod b19, and the bottom end of the pull rod b19 is fixedly connected to the outer wall of the splint 18. Pulling the pull rod b19 upward can drive the splint 18 to move upward together. The inner wall of the frame 16 is fixedly connected with a guide rod 17, and the bottom end of the guide rod 17 is fixedly connected to the outer wall of the base 1. The outer wall of the guide rod 17 is slidably connected to the inner wall of the splint 18. The guide rod 17 ensures that the splint 18 will not deviate during the movement in the vertical direction. The side wall of the base 1 is provided with a first scale 14, and the side wall of the clamping block 7 is provided with a second scale 15.

[0033] Working principle: pull the pull rod b19 outward to place the cable under the clamping plate 18 and between the two sets of clamping blocks 7, then release the pull rod b19, the reset spring b20 pushes the clamping plate 18 to lower and press the cable, and then pull the pull rod a11 outward to release the clamping block 12 from the limit groove 13. At this time, the pull rod a11 can be rotated to drive the rotating shaft 3 to rotate, so that the slider 5 slides along the slide groove 6, prompting the push rod 4 to move slowly toward the center, driving the clamping block 7 to move closer to the center. At the same time, the inner rack 8 at the bottom of the clamping block 7 drives the gear 9 to rotate, so that the other set of inner racks 8 drives the clamping block 7 to move closer to the center together to fix the cable. After fixing, release the pull rod a11, the reset spring a10 pulls the pull rod a11 to reset, and drives the limit block 12 to be re-engaged in the limit groove 13 and fixed. At this time, the rectangular protrusion structure on the side wall of the clamping block 7 and the clamping plate 18 cooperate with the two sets of scales to more intuitively see the diameter and height of the cable, and the observation is more accurate.
