Description

One-piece tool locking structure and tool setting seat

The present invention relates to an article for positioning tools; in particular, it discloses an innovative structural form of a one-piece tool locking structure that can be used to set a sleeve.

A sleeve is a tool used to set a bolt or nut and provide convenience for a socket wrench to pull the bolt or nut to rotate. The sleeve has a square sleeve groove, and four grooves are formed on the peripheral side of the sleeve groove. wall and four concave arc-shaped connecting edges respectively interposed between each of the groove walls, and each of the groove walls is respectively concaved with a curved positioning concave edge.

US8499935 patent document discloses a tool fixing seat, the tool fixing seat is provided with a sleeve sleeve, and the sleeve is positioned by rotating and locking, so as to provide convenience for storing and moving the sleeve.

The tool fixing seat includes a sleeve socket column, which is made of plastic or other elastic materials, and matches the four groove walls of the sleeve groove. The socket socket column system is approximately eight A polygonal cylinder, one end of the socket socket column is the column head end, the other end is the column foot end, the column head end and the column foot end are opposite along the axial direction of the sleeve socket column, the sleeve sleeve The lateral peripheral edge of the post forms a side portion, the side portion is located between the column head end and the column foot end, and the side portion includes eight abutment surfaces and eight abutment surfaces distributed between each of the abutment surfaces. a convex angle, when the sleeve is set on the tool holder, the sleeve utilizes The sleeve socket is sleeved with the socket column, the column head end and the peripheral side relatively enter the sleeve groove, and four of the abutment surfaces are respectively adjacent to each of the groove walls, and the other four The abutment surfaces are respectively facing the connecting edges, when the sleeve is rotated to change the abutment surfaces on which the groove walls are respectively abutted, the material of the sleeve socket column is elastic, so that part of the protruding corners Can respectively lean against and slide along each of the groove walls, and a relative friction effect is formed between the lobes and the trough walls, and as the lobes slide along the groove walls, the friction The action presents a phenomenon of increasing and then decreasing. Through the sleeve feedback to the hand of the user who clamps and operates the sleeve to rotate, it provides the user with a basis for judging whether the abutting surface is adjacent to the groove wall. The hand The feeling of sensing the change of friction is generally called the operating feel.

A positioning protrusion is provided on one of the abutment surfaces, and the sleeve cannot be disengaged from the sleeve sleeve along the axial direction of the sleeve socket post by the positioning protrusion protruding from the corresponding positioning concave edge. The post is configured so that the sleeve is locked and positioned on the socket post of the sleeve.

According to the actual application experience, the tool holder still has the following problems and disadvantages: in accordance with the relative configuration of the groove walls in space, the abutment surfaces are arranged in an octagonal shape to form the protruding corners. Each adjacent abutment surface forms an included angle of 135°. In order to make the abutment surface closely abut against the groove wall, the two abutment surfaces located at the radial ends of the circumferential side part The distance is matched with the distance between the two groove walls at the radial ends of the sleeve groove. When the sleeve is arranged on the sleeve socket column, the loosening phenomenon of the matching relationship between the sleeve and the socket socket column is avoided. For this reason, when the sleeve is sleeved on the sleeve socket column, the part of the peripheral side adjacent to the column head end is not easy to relatively enter the sleeve groove, and the convenience of use needs to be improved.
