Description

Suction screw fast fixing post

The present invention relates to a screw driver head structure, and more particularly to a quick-release fixing post for a suspension screw having an automatic magnetic attraction function.

According to the conventional tool post for screws, if it is approved by the Department of Health, the approval of the certificate number No. M373803 of February 11, 1999, "the improvement of the tool post structure of the suction screw", which mainly includes: After the rod body and the sleeve are assembled and fixed, the fastener has a proper distance between the slot and the positioning fastener of the post body, and the opening of the receiving space of the front end of the post body and the sleeve There is a displacement space between the accommodating grooves; in summary, the displacement gap formed between the connecting rod body and the sleeve allows the sleeve to be further displaced and moved forward, and the absorbing member can be automatically forwardly forward. Magnetically fixing the edge of the screw member and providing a gap between the elastic member and the positioning fastener and the limiting end, so that the frictional resistance of the connecting rod body can be reduced when the rotating body is rotated, but the above is more detailed. It is not difficult to find that there are some shortcomings in the structure. The main reason is as follows: the elastic member is disposed between the limiting end and the positioning fastener, that is, the sleeve and the connecting rod body are only opposite each other. The front end is provided with an elastic member, which causes the sleeve to be connected thereto The rod body is not in a fixed position, and when the sleeve is located at a position biased toward the rod body, the distance between the sleeve and the screw is insufficient to form an automatic magnetic attraction effect, so that the user needs to push the other hand The sleeve forms a magnetic state, and when the screw lock completes the separation of the screw, the sleeve will not receive any thrust to return to the original position, so that the sleeve will remain in the position of the magnetic screw, and still needs to be used. Another one The hand pushes the sleeve back, or directly tries to engage another screw while the screw is not exposed, which proves that the conventional structure cannot achieve true automatic magnetic attraction.

Furthermore, the prior art of the patent No. M373803 discloses a tool post structure in which an elastic body is mounted on a combined structure between a limit end of the post and a limit retaining edge of the sliding sleeve, that is, the sliding The sleeve is provided with an elastic body only at the opposite rear end of the post. When the screwdriver head engages the screw, the sliding sleeve requires the user to push the sliding sleeve with the other hand to form a magnetic state of the screw. The utility model has the disadvantage that the screw lock operation is not easy to be performed. If the sliding sleeve is adjusted to be closer to the screw position in order to overcome the above-mentioned missing, the sliding sleeve will be too short to be directly pushed backward, and the user will It is not easy to hold the screwdriver head and remove it for replacement, so there is still a significant lack of difficulty in the operation of the screw lock.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The technical problem to be solved by the present invention is to provide a quick-release fixing post for the suspension screw in view of the above-mentioned shortcomings existing in the prior art.
