[0022] After the wiring harness is installed, it will be tangent to the surface of the rubber pad 18 and the support block 3. The arc-shaped support plate 16 is adapted to the arc-shaped groove 11 and is tangent to the side surface of the ball 15. The opposite ends of the coil spring 13 are fixedly connected to the front and rear ends of the movable slider 17 respectively. The protrusions on the left and right sides of the arc-shaped support plate 16 are adapted to the limiting slide groove 14. The inner part of the rubber pad 18 is arc-shaped and adapted to the wiring harness.

[0023] The arc-shaped support plate 16 moves on the surface of the ball 15, and during the movement, the moving slider 17 moves synchronously inside the moving slide groove 12, so that the wiring harness can not only be stretched normally, but also automatically reset by the elastic force of the coil spring 13 at the end of the stretching.

[0024] Specifically, such as Figure 4 As shown, a limiting structure for the support block 3 is installed on the inner side surface of the fixed cover 2 and the interior of the support block 3. The limiting structure includes a fixed slider 33 fixedly connected to the inner side surface of the fixed cover 2 and a movable slide groove 31 provided on the outer side surface of the support block 3;

[0025] A second limiting groove 32 is formed on the side surface of the second movable chute 31. The left and right surfaces of the fixed slider 33 are fixedly connected to limiting blocks 34. The front and rear ends of the fixed slider 33 are fixedly connected to a second coil spring 35. The second coil spring 35 is used to fix one end of the fixed slider 33 to the second movable chute 31.

[0026] The support block 3 moves along with the wiring harness, and at the end of the movement is recovered by the pulling force of the coil spring 2 35 , thereby resetting the wiring harness.

[0027] Specifically, such as Figure 4 As shown, the fixed slider 33 is matched with the second movable slide groove 31 , and the limiting block 34 is matched with the second limiting slide groove 32 .

[0028] Specifically, such as Figure 1 and Figure 2 As shown, a connecting block 4 is fixedly connected to the side surface of the right fixing cover 2, and an adaptor block 5 is fixedly connected to the side surface of the left fixing cover 2.

[0031] The working principle and usage process of the utility model: During the installation process, the staff first places the suspension base 1 on the surface of the six-joint robot, and then uses bolts to pass through the threaded holes 7 to fix the suspension base 1 to the six-joint robot. When the cable harness is long, multiple devices can be used;

[0032] Then the wiring harness can be neatly arranged and placed inside the arc-shaped support plate 16 in contact with the rubber pad 18. Then, the left and right fixing covers 2 are closed at the same time, and the adapter block 5 is inserted into the connection groove 41. Then, the adapter block 5 is passed through the second threaded hole 42 and the third threaded hole 43 respectively to complete the connection of the fixing cover 2. When the fixing cover 2 is fully connected, it will also drive the support block 3 to press and fix the wiring harness, thereby avoiding shaking and friction of the wiring harness during use, improving the safety of the wiring harness and extending the service life of the wiring harness.

[0033] When the six-joint robot is working to stretch the wire harness, the wire harness will synchronously drive the support block 3 and the arc-shaped support plate 16 on the side surface to move, and can clamp and limit the wire harness while avoiding restraining the movement of the wire harness, thereby not only improving the safety of the wire harness, but also avoiding friction and collision between the wire harness and the side of the six-joint robot, thereby extending the service life of the six-joint robot.
