AI Technical Summary

Problems solved by technology

The surface of the hexagonal wrench is smooth and elastic, so that the driving part can enter and exit the screw groove conveniently, and the small steel ball that can advance and retreat can fill the gap between the screw groove and the driving part. The small steel ball is easy to retract into the accommodation groove when the screw is used, and cannot firmly fill the gap between the screw groove and the driving part. The structural strength of the design is not enough to keep the driving part firmly attached to the screw groove when the driving part is driven. inside

Abstract

The present invention provides an improved structure for hexagon spanner, which comprises a body of the hexagon spanner. At least one end of the body is provided with a hexagonal drive division, wherein, the drive division is provided with a bolt hole radially, a countersunk head screw which can extend the external diameter of the drive division is arranged in the bolt hole through thread connection. The hexagon spanner of the present invention has a strong intensity, is adapted to the flight channels of different sizes, and can fill up the spacing between the flight channel and the drive division stably.

Description

【Technical field】 [0001] The invention relates to a wrench, in particular to an improved structure of a hexagonal wrench. 【Background technique】 [0002] The hexagonal wrench is a kind of common hand tool. The existing hexagonal wrench is L-shaped, with a curved part in the middle, and the two ends are driving parts. The outer peripheral ring of the driving part is set as a hexagonal surface, and the driving part is The screw groove of the screw is installed, and the user pulls the driving part at the other end to lock or disengage the screw. In order to make the driving part fit into the screw groove smoothly, generally the driving part is slightly smaller than the screw groove of the screw, but the inner diameter of the screw groove is often not the same as the driving part, and it is difficult to find a hexagonal wrench that just fits the inner diameter of the screw groove. Therefore, if a hexagonal wrench is directly used to turn a screw that does not fit the inner diam...
