[0033] The bottom end of the base 1 is fixedly connected with a limiting groove 4, which can cooperate with the base 1 to limit the relevant components. The limiting groove 4 is slidably connected with a plug rod 5 inside, which can slide in the limiting groove 4 to fix the relevant components. The outer part of the two drive rods 3 is slidably connected with a socket sleeve 6, which can cooperate with the drive rod 3 to drive the socket sleeve 6 and the subsequent components to move through the movement of the drive rod 3. The proximal end of the two socket sleeves 6 is fixedly connected with a clamp 7, and the proximal end of the two clamps 7 is provided with a groove, which can stably realize clamping operation.

[0034] The bottom end of the clamp 7 is slidably connected with a limiting seat 8, which can cooperate with the base 1 to support the relevant components and limit the subsequent components. The bottom end of the limiting seat 8 is fixedly connected with four plug rods 9, which can cooperate with the subsequent components to fix the relevant components and increase the stability of the device.

[0035] Referring to Figure 1 and Figure 4 , the cleaning assembly comprises a bracket 10 made of aluminum alloy, which is light in quality and has sufficient strength to provide a stable platform for the operation of the subsequent components. The top end of the bracket 10 is fixedly connected with a fixed frame 11, which can provide support for the subsequent components to enable them to operate stably. The right end of the fixed frame 11 is fixedly connected with a motor 12, which can stably output power to drive the relevant components to rotate at any time.

[0036] The driving end of the motor 12 is fixedly connected with a rotating shaft 13, which can rotate inside the fixed frame 11 to ensure that it can drive the subsequent components to rotate without deviation. The top end of the rotating shaft 13 is fixedly connected with a cleaning hydraulic machine 14, which can provide power for the subsequent components to ensure the stable operation of the cleaning operation, and can adjust the angle under the drive of the rotating shaft 13 to avoid affecting the subsequent welding operation.

[0037] The driving end of the cleaning hydraulic machine 14 is fixedly connected with a brush holder 15 made of aluminum alloy, which is light in quality and strong in corrosion resistance, can reduce power consumption and prolong service life. The left and right ends of the brush holder 15 are fixedly connected with soft brushes 16 made of nylon material, which can effectively clean the surface of the relevant components without causing damage to the relevant components.

The second inserting rod 9 slides downward in the base 1 while moving downward. The clamp 7 drives the socket sleeve 6 to move downward while moving downward, and the socket sleeve 6 slides downward outside the driving rod 3. When the bottom end of the limiting seat 8 moves to contact the top end of the base 1, the worker pushes the first inserting rod 5 to insert the first inserting rod 5 into the second inserting rod 9, and the movement of the first inserting rod 5 is supported and limited by the limiting slot 4, thereby completing the installation of the clamping mechanism.
