Beneficial Effects

[0009] 1. By setting the inner groove and the auxiliary block, when the device is in use, after the main body rotates, it will drive the auxiliary block to rotate together, so that the auxiliary block controls the airflow through the inclined groove to guide the airflow, so that the airflow enters the inner groove through the outer groove, so that the airflow can quickly pass through the inner groove. Since the inner groove is an inclined structure and is arranged in a ring shape, the airflow can quickly take away the heat emitted by the main body, thereby improving the heat dissipation effect and heat dissipation efficiency, and prolonging the service life of the main body;

[0010] 2. By setting the extrusion piece, the storage piece will be driven to rotate during the operation of the device, and then the inner plate and the extrusion piece will be displaced inside the storage piece by the rotational swinging force, thereby pushing the grease or the grease to be slowly discharged from the inside of the storage piece, so that the grease can be continuously added through the connecting pipe and the through groove, so that the device can automatically and continuously add grease, so that the main body can be maintenance-free. At the same time, after the grease is added, since the top of the extrusion piece is an inclined structure, the top of the extrusion piece can first contact the internal top of the storage piece, so that the extrusion piece is gradually squeezed and deformed, so that the residual grease can be completely squeezed out, and at the same time, the sealing piece rotates with it, so that the residual grease in the through groove and the connecting pipe can be completely filled and used, avoiding waste;

[0011] 3. By setting the force block and the contact block, after the main body is fixed, the pushing plate can use elasticity to continuously push the moving part and the fixed head, so that the outer end of the moving part and the fixed head can be in contact and fixed with the external object. At the same time, when the object is inserted into the main body, it can be inserted into the inner part and the main body through the contact block, and then the adjusting part is displaced by human power. After the adjusting part is displaced, the card block can be contacted and fixed with the card slot. After the adjusting part moves, the force block can be gradually squeezed through the pressure groove, so that the force block can drive the pushing block to tilt, and then squeeze the contact block, so that the contact block is continuously stressed and contacted and fixed with the object in an anti-slip manner, thereby improving the fixing effect.
