When the device is in use, the device is fixed on the cylindrical rod through the installation component. A fixing bolt and a fixing nut are provided at the hinge between the installation component and the bracket 1. The freedom of rotation between the bracket 1 and the installation component is adjusted by cooperating with the fixing bolt and the fixing nut. After the installation component is fixed on the cylindrical rod, the angle of the bracket 1 can be adjusted, so that the fixing block 2 can adjust the angle when fixing the lead, thereby improving the flexibility of the device. After adjustment, the bracket 1 and the installation component can be locked by the fixing bolt and the fixing nut. The lead is fixed through the lead hole in the fixing block 2 and the fixing component. The lead passes through the lead hole, and then the lead is fixed by the synchronous gathering movement of the fixing clamp 10.

The upper clamp 3 and the lower clamp 4 in the installation assembly of the device are rotatably connected. During installation, the upper clamp 3 is rotated to open 180 degrees, and the cylindrical rod is clamped in the groove 6 of the lower clamp 4. Then, the upper clamp 3 is rotated to the other side of the cylindrical rod, and then the tightening bolt 5 is rotated to enter the upper clamp 3 from the position of the groove 6. Then, the upper side of the groove 6 is tightened by tightening the nut 77, so that a closed ring is formed between the upper clamp 3 and the lower clamp 4, and the fixing work of the installation assembly on the cylindrical rod is completed; the fixing assembly is adjusted by rotating the guide plate 8, and the guide plate The contour of the slide groove 12 on 8 is a spiral line structure, which gradually approaches the center of the circle from the inside to the outside. The slide groove 12 on the fixed plate 9 points to the center of the circle of the fixed plate 9. As shown in Figure 4, when the guide plate 8 rotates counterclockwise, the slide groove 12 at the slide rod 25 gradually approaches the center of the circle of the guide plate 8. At this time, the slide rod 25 drives the slide sleeve 13 to move along the guide groove 14 toward the center of the fixed plate 9. The movement of the slide sleeve 13 drives the guide rod 16 to move inward, and the guide rod 16 drives the fixed clamp 10 to move inward. The three groups of fixed clamps 10 move inward synchronously so that the fixed clamps 10 clamp the lead wires.

The tightening nut 7 is fixedly connected with a handle, which can increase the strength point of the tightening nut 7. During operation, the nut can be tightened manually by the handle without the need for tools, which is convenient for operation.

The guide plate 8 is provided with a plurality of ratchet grooves 18, and the side of the ratchet groove 18 is matched with a pawl 19, and the pawl 19 is rotatably connected to the fixed block 2, and a spring 20 is provided on the upper side of the pawl 19 to apply force to the pawl 19 downward; the width of the pawl 19 is greater than the width of the guide plate 8, and a cam block 21 is provided below the pawl 19, and the cam block 21 is rotatably connected to the fixed block 2, and the cam block 21 is located at the rear side of the guide plate 8; the cooperation principle between the ratchet groove 18 and the pawl 19 on the guide groove 14 is the same as that of the existing The ratchet pawl 19 in the technology is used on the same principle. The ratchet can only guide the rotation relative to the pawl 19. Under the cooperation of the ratchet groove 18 and the pawl 19, the guide plate 8 can only rotate counterclockwise without the interference of external force, thereby ensuring the locking state of the lead wire. When it needs to be loosened, by rotating the cam block 21, when the cam block 21 contacts with the pawl 19, the cam block 21 pushes the pawl 19 to rotate upward, thereby compressing the spring 20, and disconnecting the cooperation state between the pawl 19 and the ratchet groove 18, and then the guide plate 8 can be rotated in the opposite direction.

Example 2

The structure is the same as the above embodiment, as shown in Figure 5, the specific difference of this embodiment is that a connecting bolt 22 is fixedly connected to the bracket 1, a connecting block 23 is fixedly connected to the fixing block 2, and the connecting bolt 22 passes through the connecting block 23 and is threadedly connected to the connecting nut 24.
