A transmission assembly 59 is arranged on the outer wall of the connecting shaft 58, and a long shaft 501 is arranged inside the transmission assembly 59.
[0035] Furthermore, the threads of the outer walls at both ends of the long screw 51 are in opposite directions, and the threaded plates 52 are slidably connected to the inner wall of the connection box 1 , so that the rotational motion of the long screw 51 can be converted into the opposite motion of the two threaded plates 52 .
[0036] Furthermore, a sliding opening matching the long plate 55 is opened inside the threaded plate 52, and the threaded plate 52 is slidably connected to the outside of the long plate 55 through the opened sliding opening, ensuring that the long plate 55 will not rotate during the rotation of the long screw 51, so that the threaded plate 52 can move stably.
[0037] Furthermore, the transmission assembly 59 includes a driving bevel gear and a driven bevel gear, the connecting shaft 58 is fixedly connected to the inner ring of the driven bevel gear, the long shaft 501 is fixedly connected to the inner ring of the driving bevel gear, and the driving bevel gear and the driven bevel gear are meshed with each other, so that the long shaft 501 can drive the connecting shaft 58 to rotate through the transmission of the transmission assembly 59 to achieve the driving purpose.
[0038] Furthermore, a rotating hole 1 is opened on the right side of the connection box 1, and the connecting shaft 58 passes through the rotating hole 1 and rotates, thereby supporting the connecting shaft 58.
[0039] Furthermore, a rotating hole 2 is opened on the front side of the side box 1 3 , and the front end of the long axis 501 passes through the rotating hole 2 and rotates, which plays a role in stabilizing the support of the long axis 501 .

[0042] Embodiment 2
[0043] See also Figures 1 to 8 On the basis of the first embodiment, the cutting mechanism 6 further comprises a motor 61, the motor 61 is fixedly connected to the inner wall of the side box 2 4, the output end of the motor 61 is fixedly connected to an output shaft 62, the outer wall of the output shaft 62 is fixedly connected to a gear 3 63, the outer ring of the gear 3 63 is meshed with a gear 4 64, the inner ring of the gear 4 64 is fixedly connected to a long rod 65, and the outer wall of the long rod 65 is fixedly connected to a cutting knife 66, so as to ensure the integrity of the burning end of the wire and cable.

[0045] In actual operation, when this device is used, first, the device can be installed inside the wire and cable combustion detection equipment through the mounting plate 2, and then the wire and cable that need to be burned is inserted into the inner side of the clamping plate 54, and then the hand wheel is shaken to drive the long shaft 501 to rotate, and the long shaft 501 drives the connecting shaft 58 to rotate through the transmission of the transmission assembly 59, and the connecting shaft 58 can synchronously drive the long screw 51 to rotate through the sequential transmission of gear 2 57 and gear 1 56. Since the long screw 51 and the threaded plate 52 are threadedly connected, and the threaded plate 52 can slide and limit on the outer side of the long plate 55, the rotational motion of the long screw 51 will be converted into the linear motion of the threaded plate 52. At the same time, the outer wall threads at both ends of the long screw 51 are in opposite directions, so the threaded plate 52 will drive the clamping plate 54 to move toward the outside of the wire and cable through the connecting rod 53, so that the clamping plate 54 can play the purpose of stably clamping the wire and cable.
[0046] Then, during the vertical burning process of the wires and cables, after the combustion detection equipment records and outputs the combustion data, the motor 61 can be started, and the output end of the motor 61 can drive the output shaft 62 to rotate. The output shaft 62 drives the long rod 65 to rotate through the transmission of gear three 63 and gear four 64, so that the cutting knife 66 can make a circular motion along the axis point of the long rod 65. When the cutting knife 66 contacts the wires and cables, the burned part of the bottom end of the wires and cables will be cut off, thereby separating the burned end from the unburned end, so as to ensure the flatness of the burned end of the wires and cables.
