Problems solved by technology

The problem with this process is that it keeps repeating unnecessary redundant steps, and the wasted time and redundant steps are all the more apparent when a single fastener needs to be turned multiple times and the actual job requires manipulation of multiple fasteners
Therefore, the present invention proposes a novel folding wrench to solve the problem of inefficiency

Embodiment

[0021] figure 1 One embodiment of the invention is shown. Such as figure 1 As shown, a folding wrench includes: a head 1, a working part 2, a holder 3, a folding device 4, a buckle device 5, a handle 6 and a central shaft 7; the head 1 is fixed on the working part 2 One end of the head, the direction of the head 1 and the working part 2 are in a common vertical relationship. The folding device 4 is arranged at the tail of the other end of the working part 2. The folding device 4 is also hinged with the central shaft 7. The central shaft 7 is the main force transmission part in the wrench. The handle is 6 to produce auxiliary force transmission to the central shaft 7 . The fixer 3 is arranged on the working part 2, and is fixedly connected with the folding device 4 in a locked state. The buckle device 5 is fixedly connected with the central shaft 7 . Such as image 3 As shown, the hollow handle 6 is sleeved on the central axis 7, but the relationship is not closely attach...

Abstract

The invention relates to a folding type wrench. The folding type wrench comprises a head part, a working part, a fixator, a folding device and a grip handle. The head part is fixed to one end of the working part, the fixator and the folding device are arranged at the other end of the working part, and the folding device is also connected with the grip handle. The folding type wrench has the advantages that the characteristic that the grip handle can be folded to form a perpendicular angle with the working part is utilized, and the efficiency of using the wrench by operators can be improved substantially.

Description

technical field [0001] The present invention relates to a tool for fastening or dismounting, more particularly, to a folding wrench. Background technique [0002] At present, the handle of most wrenches and the first half of the working part are fixedly connected in a straight line. When the operator actually uses this type of wrench, when the body and the equipment to be fixed by the fastener are not moving, the common workflow is: put the wrench head on the fastener that needs to be fixed or loosened by hand , turn a certain angle in one direction, loosen the wrench from the fastener and adjust it back to the original angle. The operator repeats the above steps until the fastener is completely loosened or fixed. The problem with this process is that it keeps repeating unnecessary redundant steps, and the wasted time and redundant steps are all the more apparent when a single fastener needs to be turned multiple times and the actual job requires multiple fasteners to be w...
