The bottom of the right bending plate 2 is fixedly connected to the right part of the upper surface of the base plate 1, and the bottom of the left bending plate 2 is movably connected to the left part of the upper surface of the base plate 1. The tops of the two bending plates 2 are fixedly connected with fixing mechanisms 5, the tops of the two bending plates 2 are movably connected with a cable protection tube body 3, and the front side of the right bending plate 2 is fixedly connected with a bending mechanism 4.

[0027] It should be noted that, by means of the two limit plates 50, the cable protection tube body 3 can be limited to a certain extent, and by means of the limit rod 55, the cable protection tube body 3 can be prevented from moving. At the same time, the slide plate 58 can block the fixed block 52, and the anti-slip pad 53 that is in close fit with the surface of the cable protection tube body 3 can be used to prevent the cable protection tube body 3 from positional displacement, thereby effectively preventing the cable protection tube body 3 from moving during the bending process. By starting the motor 46, the gear set can be driven to rotate, thereby driving the bending plate 2 on the left to rotate clockwise, thereby bending the cable protection tube body 3. At the same time, the axis of the scale plate 44 set at the rear is consistent with the axis of rotation of the left bending plate 2, so that during the rotation of the left bending plate 2, it will always correspond to the scale line on the scale plate 44, thereby being able to control a more precise bending angle and achieve a better bending effect.

[0029] It should be noted that, first, the cable protection tube body 3 to be bent is placed in the middle of the two limit plates 50. The distance between the two limit plates 50 is slightly larger than the cable protection tube body 3, so that the cable protection tube body 3 can be limited to a certain extent. Then, the cable protection tube body 3 is moved to the right end so that the cable protection tube body 3 contacts the baffle 54. The limit rod 55 set on the baffle 54 will enter the cable protection tube body 3 to prevent the movement of the cable protection tube body 3. By pulling the pull rod 59 backward, the pull rod 59 moves backward along the slide groove 502.

[0037] It should be noted that by starting the motor 46, the gear 1 47 is driven to rotate counterclockwise, and the gear 1 47 is meshed with the gear 2 48, thereby driving the gear 2 48 to rotate clockwise, so that the rotating shaft 42 rotates clockwise on the two connecting blocks 1 41, and the bending plate 2 on the left is fixed on the rotating shaft 42 through the connecting block 2 43, thereby driving the bending plate 2 on the left to rotate clockwise. Square grooves 40 are provided on the front and rear sides of the bottom plate 1. The size of the square groove 40 is larger than the size of the connecting block 2 43, thereby ensuring the smooth rotation of the left bending plate 2, and then the cable protection tube body 3 can be bent.

[0041] It should be noted that square grooves 40 are provided on the front and rear sides of the bottom plate 1 , and the size of the square grooves 40 is larger than the size of the second connecting block 43 , thereby ensuring the smooth rotation of the left bending plate 2 .

[0042] The working principle of the utility model is as follows: first, the cable protection tube body 3 that needs to be bent is placed in the middle of the two limit plates 50. The distance between the two limit plates 50 is slightly larger than the cable protection tube body 3, so that the cable protection tube body 3 can be limited to a certain extent. Then, the cable protection tube body 3 is moved to the right end so that the cable protection tube body 3 contacts the baffle 54. The limit rod 55 set on the baffle 54 will enter the cable protection tube body 3 to prevent the movement of the cable protection tube body 3. By pulling the pull rod 59 backward, the pull rod 59 moves backward along the slide groove 502, and the slide groove is set. 502 ensures the smooth movement of the pull rod 59, thereby driving the slide plate 58 to move backward, compressing the two springs 501, and then rotating the fixed block 52 backward so that the rear part of the fixed block 52 rests on the receiving plate 56, loosening the pull rod 59, and under the action of the two springs 501, the slide plate 58 moves forward, thereby blocking the fixed block 52, so that the fixed block 52 cannot rotate. At the same time, the anti-skid pad 53 arranged in the middle of the fixed block 52 will contact the cable protection tube body 3. The anti-skid pad 53 is an annular plate and fits the surface of the cable protection tube body 3. The anti-skid pad 53 fits with the cable protection tube body 3 to achieve a large friction force to prevent the cable protection tube body 3 from being offset. The fixed blocks 52 are arranged at one position on each side, so that the two ends of the cable protection tube body 3 can be fixed, effectively preventing the cable protection tube body 3 from moving during the bending process. By starting the motor 46, the gear 1 47 is driven to rotate counterclockwise, and the gear 1 47 is meshed with the gear 2 48, thereby driving the gear 2 48 to rotate clockwise, so that the shaft 42 rotates clockwise on the two connecting blocks 1 41, and the bending plate 2 on the left side is connected by The connecting block 2 43 is fixed on the rotating shaft 42, thereby driving the bending plate 2 on the left to rotate clockwise.
