It is inconvenient for one person to operate, and the shearing device has a single function during the cable laying process and cannot effectively limit the cable. When fixing the cable, the position of the shearing device needs to be adjusted to achieve smooth cutting, which affects the cutting efficiency. Utility Model Content

[0006] Furthermore, the fixing plate and the limiting plate are both arc-shaped plates, a rubber pad is connected to the inner side of the fixing plate, and a plurality of anti-slip protrusions are provided on the inner side of the rubber pad.

[0008] Furthermore, sliding rods are connected to both sides of the movable frame, and limiting grooves matching the sliding rods are provided on the fixed frame.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] The cable can be quickly fixed, and the operation is simple and convenient: the driving structure adopts a bidirectional screw and a movable rod transmission, which can realize the movement of the fixed plate controlled by the second motor. The cable can be loosened and fixed by controlling the forward and reverse rotation of the second motor. The operation is simple and convenient. In addition, the two fixed plates move relative to each other to ensure that the fixed height of the cable matches the limit structure and the shearing structure, thereby ensuring a good shearing effect.

A motor 2 14 for driving the bidirectional screw 12 is connected in the bracket 1. The bidirectional screw 12 is driven to rotate by the motor 2 14, so that the two fixed plates 2 can move simultaneously, thereby ensuring that the fixed position of the cable is flush with the shearing position, and achieving a good shearing effect.

[0021] Combined with Figure 2 , Attachment Figure 3 The limiting structure includes a symmetrically arranged limiting plate 3, the fixed plate 2 and the limiting plate 3 are both arc-shaped plates, a rubber pad 11 is connected to the inner side of the fixed plate 2, and a plurality of anti-slip protrusions are arranged on the inner side of the rubber pad 11. The rubber pad 11 can prevent the fixed plate 2 from scratching the cable, and the anti-slip protrusions can increase the fixing stability of the cable.

[0022] Combined with Figure 3 , Attachment Figure 4 , Attachment Figure 5 , two limit plates 3 are respectively fixedly and rotatably connected to the bracket 1, one end of the two limit plates 3 is connected by a spring 4, and a plurality of balls 5 are rotatably arranged on the opposite side of the limit plate 3, and the shearing structure includes a cutting wheel 6, a mobile frame 7, a motor 8 and an electric push rod 9, the cutting wheel 6 is rotatably connected to the mobile frame 7 and driven by a motor 8 fixed on the mobile frame 7, the bracket 1 is connected with a fixed frame 10 matching the mobile frame 7, and the mobile frame 7 is driven by an electric push rod 9 fixed on one side of the fixed frame 10.

During the cable laying process, the ball 5 will roll with the movement of the cable. When the cable needs to be sheared, the motor 2 14 is controlled to work, and the motor 2 14 drives the bidirectional screw 12 to rotate, so that the two moving rods 13 drive the fixed plates 2 to approach each other until the fixed plates 2 contact the cable and fix it. The two groups of fixed plates 2 can fix the two sides of the cable cutting position, turn on the motor 1 8, and the motor 1 8 drives the cutting wheel 6 to rotate.
