Dual-specification adaptor

Abstract

The dual-specification adaptor is in a columnar shape and possesses a first end and a second end. The first end is concavedly provided with a first nested hole and a second end is concavedly provided with a second nested hole. The pitch diameter of the second nested hole is greater than the pitch diameter of the first nested hole, so as to drive a screw lock assembly with larger size. The peripheral ring of the adapter is provided with a detent; one end of the detent and the plane of the first or second end of the adaptor can extend to intersect. In addition, the dual-specification adaptor can classify for recognition; the external diameter of the adaptor detent can be naturally greater than the hole diameter of conventional combined hole, so that the adaptor can be easily linked to a spanner driving hole which is not easy to deform.

Description

technical field [0001] The present invention specifically refers to a double-standard socket piece in which the first and second joint holes are correspondingly arranged at both ends. Background technique [0002] Generally, the sleeve is mainly provided with a regular hexagonal fitting hole at one end, and a square coupling hole at the other end. The fitting hole is used for inserting the screw lock assembly (nut or bolt head) of the same size. As for the combination hole, the wrench joint is used for combination, whereby the wrench can tighten the screw lock assembly through the sleeve, so as to achieve the connection or fastening function in the mechanical structure or building components. [0003] Since the sleeve only has a fitting hole of a single size, it can only be applied to a screw lock assembly of a single specification. As a result, the user must prepare about ten sets of sockets of different sizes to be sufficient, which takes up a lot of space and is unfavorab...

Problems solved by technology

[0003] Since the sleeve only has a fitting hole of a single size, it can only be applied to a screw lock assembly of a single specification. As a result, the user must prepare about ten sets of sockets of different sizes to be sufficient, which takes up a lot of space and is unfavorable. Portable, in addition, it also increases the inconvenience that users have to replace different sleeves one by one

[0004] Therefore, there is a kind of "Structure Improvement of Sleeve" such as China Taiwan Announcement No. 256148, which is mainly provided with two fitting holes of similar size coaxially at one end of the sleeve, and a square joint is recessed at the other end. Holes, so that the two matching holes can provide two types of screw lock components with similar specifications, so as to simplify the number of sets of sockets one by one. However, this kind of sleeve is limited by the structural design and cannot integrate the size difference The two sets of large joint holes do have limitations in configuration. In addition, it also causes troubles for users to distinguish the sizes of the two sets of joint holes.

[0005] As for China Taiwan’s announcement No. I359061 "double specification sleeve" invention patent case, it can improve the similar size limit of the No. 256148 patent case, so that two fitting holes of different sizes are integrated at one end of the sleeve, and are less affected. The size is similar to the limit, but the structure of the invention patent case is not streamlined, resulting in an uneconomical price. More importantly, the two fitting holes of different sizes are also located at one end of the socket, which is still visible sex problems
