The output shafts of the plurality of spring telescopic rods 6 extend into the plurality of arcuate slots 4. The plurality of arcuate clamps 7 are respectively fixedly mounted on the output shafts of the plurality of spring telescopic rods 6, and the plurality of arcuate clamps 7 are respectively adapted to the plurality of arcuate slots 4 and the plurality of arcuate clamps 5.

[0025] The outer walls on both sides of the mounting clamp block 1 and the mounting clamp block 2 2 are both provided with through slots, the two through slots on the mounting clamp block 1 and the two through slots on the mounting clamp block 2 2 correspond one to one, and the mounting clamp block 1 is provided with two height adjustment mechanisms.

[0026] The height adjustment mechanism includes a storage cylinder 8, a support rod 9, a sealing piston 10, a hollow cylinder 11, a piston rod 12, a sealing piston 2 13, a connecting pipe 14, a connecting pipe 2 15 and two valves. The storage cylinder 8 and the hollow cylinder 11 are both installed in the through groove on the mounting clamp 1.

[0027] The support rod 9 is slidably installed on the storage tube 8, and the top end of the support rod 9 is fixedly connected to the inner wall of the top of the through groove on the mounting clamp 2. The sealing piston 10 is slidably installed in the storage tube 8, and the bottom end of the support rod 9 extends into the storage tube 8 and is fixedly connected to the sealing piston 10.

[0028] The piston rod 12 is slidably mounted on the hollow cylinder 11, a handle is fixedly mounted on the top of the piston rod 12, the sealing piston 13 is slidably mounted in the hollow cylinder 11, and the bottom end of the piston rod 12 extends into the hollow cylinder 11 and is fixedly connected to the top of the sealing piston 13.

[0030] The working principle of the wire harness anti-crossing device provided by the utility model is as follows:

[0031] The first step: when in use, open the valve on the connecting pipe 14, and then press the piston rod 12 by the handle, so that the piston rod 12 drives the sealing piston 2 13 to move downward, causing the gas in the hollow cylinder 11 to enter the storage cylinder 8 through the connecting pipe 14, and then the gas squeezes the sealing piston 10 to drive the support rod 9 to move upward, so that the mounting clamp 2 2 is lifted, and then the valve on the connecting pipe 14 is closed, and then the wiring harness is placed on the arc clamp 1 5 and passes through the arc clamp 1 5, and then the valve on the connecting pipe 2 15 is opened, and the mounting clamp is pressed. Block 2 moves downward, causing the support rod 9 and the sealing piston 10 to move downward through the installation clamp block 2, so that the gas in the storage tube 8 enters the hollow tube 11 through the connecting pipe 2 15, causing the sealing piston 2 13 to drive the piston rod 12 to move upward to the appropriate position. When the arc-shaped clamp block 2 7 contacts the wiring harness, the valve on the connecting pipe 2 15 is closed, thereby positioning the installation clamp block 2 and also tightening and limiting the wiring harness. The spring telescopic rod 6 can play a limiting role to avoid excessive compression of the wiring harness and damage to the outer body of the wiring harness.
