A limit block 19 is fixedly installed on the surface of the damping rod 17.

[0023] The main function of the damping rod 17 is to absorb the shaking generated when the boom 10 is raised or lowered by absorbing the shaking caused by the spring 18 sleeved on the surface and the telescopic movement inside, so that the device will not be affected by vibration when grabbing things.

[0024] Among them, a sliding rod 11 is fixedly installed on the surface of the boom 10, a motor 3 12 is fixedly installed on the bottom of the boom 10, a connecting plate 20 is fixedly installed on the bottom of the damping rod 17, a fixed block 21 is fixedly installed on the bottom of the connecting plate 20, the interior of the fixed block 21 is rotatably connected to a connecting shaft 22, and the surface of the connecting shaft 22 is rotatably connected to a sliding block 23.

[0025] The sliding block 23 is slidably connected to the sliding rod 11, and its main function is to provide a certain support to the boom 10 to prevent the boom 10 from loosening after a long period of work.

[0026] An integrated fan 24 is fixedly installed inside the bracket 6 , and fan blades 25 are arranged inside the integrated fan 24 . The integrated fan 24 is located on the right side of the connecting block 1 5 .

[0027] The main function of the integrated fan 24 is to cool the entire device through the fan blades 25 to prevent the generation of large amounts of heat after long-term operation, which would affect the practical life of the device.

[0032] The working principle and use process of this utility model:

[0034] At this time, the motor 2 7 is started to drive the belt 8 to transmit, so that the support block 9 can slide to a suitable position, and then the suspension arm 10 can be adjusted by the support block 9, so that the height of the suspension arm 10 can be adjusted, which is more convenient for the motor 3 12 to accurately grasp the object;

[0036] Finally, since the device will generate a lot of heat after running for a long time, the fan blades 25 will generate a lot of heat. If the heat is not dissipated for a long time, it will affect the practical life of the device. The fan blades 25 will generate a large amount of air to dissipate heat for the entire device, thereby achieving the effect of increasing the practical life of the device.
