It is applied to the side force to cause a break, and it is urgent to improve it. [New content] - The purpose of this creation is to provide a kind of linear actuating cymbal guide shaft clamping structure, which enables the free end of the rotating shaft to be stably received by the dragon body, effectively preventing the rotating shaft from being laterally acted upon. The force is applied to cause breakage damage. In order to achieve the above object, the present invention provides a shaft guiding and positioning structure for a linear actuator, the linear actuator comprising a base, a motor fixed to one side of the remote base, and a cover on the base And a cover body formed on the other side of the motor, the shaft guiding and positioning structure comprises a shaft extending from the motor and passing through the base, a shaft formed on the cover body and corresponding to the free end of the rotating shaft a cylinder and a cap formed inside the cylinder and sleeved at a free end of the shaft, wherein a gap is formed between the outer surface of the cap and the inner wall surface of the cylinder, and The gap is filled with an adhesive to cure the bond. Compared with the prior art, the following effects have the following effects: since the free end of the rotating shaft is sufficient to support the towel body, the rotating shaft does not need to be made of high-strength steel, and the material cost and processing cost can be greatly reduced. The ring is attached to the bottom surface of the cap body, and when the liquid adhesive is filled, the adhesive can be prevented from flowing into the inner space of the machine base, and the internal transmission component is prevented from being stuck and cannot be driven; Agent Easy 4 M356032 is filled in the gap and can increase the amount of adhesive filling; by means of the = phase surface, there are rough lines and grooves to increase the mutual adhesion between the column, the cap and the curing agent.
