Embodiment Construction

[0010] see figure 1 , the fixed half ring 4 is fixedly connected between the front and rear connecting plates 1, the upper end of the fixed half ring 4 is connected with the movable half ring 2, and the movable half ring 2 is fixedly connected between the front and rear connecting plates 1 by the movable half ring pin 3, and the movable half ring 2 There is a protruding contact B at the left end, one end of the lever 7 is fixed between the front and rear connecting plates 1 with the lever positioning pin 6, and the protruding contact A and C are provided at the right end of the lever 7, and the protruding contact B is located on the protruding Between the contact A and the protruding contact C, there is a safety pin 5 on the left side of the protruding contact C. The safety pin 5 plays the role of insurance and at the same time acts as a limiter. tooth. This manufacturing technique is relatively clear to those skilled in the art.

Abstract

An open quincuncial spanner is composed of front and back connecting plates, holding rod, fixed semi-ring fixed to one end of holding rod between said front and back connecting plates, movable semi-ring finned to one end of holding rod between said front and back connecting plates, the convex contacts at the left end of movable semi-ring and the right end of holding rod, and safety pin in the left of convex contact. It can be easily restored without releasing nut.

Description

[technical field] [0001] The invention relates to the technical field of hand tools, in particular to an open mouth type ring wrench. [Background technique] [0002] At present, the existing torx wrench mainly uses the socket part set on the head of the wrench to cover the hexagonal nut, and then applies a pulling force on the wrench rod, so that the nut can be locked and disassembled. However, when locking and dismounting the nut, the existing torx wrench needs to be disengaged from the nut every time the existing torx wrench is locked or loosened, the wrench returns to its original position, and the socket part of the wrench head is set again To lock or loosen the hexagonal nut, it is necessary to achieve the purpose of fixing and dismounting the screwed parts after such complicated repeated back and forth actions. Therefore seem very inconvenient when using, and time-consuming, do not have practicability. [Content of the invention] [0003] The purpose of the present ...
