Detailed Description

The technical scheme of the preferred embodiment of the vertical dewar flask copper pipe leakage detection tool of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention. It is to be understood that the described embodiments are merely a few embodiments of the utility model, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

Example 1:

a wrench assembly for adjusting belt tension in a narrow space includes a first wrench 100 and a second wrench 200.

As shown in fig. 1, the first wrench 100 has a first wrench head 101, a first corner link 102 and a first handle 103, the first corner link 102 is fixedly connected between the first wrench head 101 and the first handle 103, the first corner link 102 has a first corner of 75 °, the length of the first handle 103 is greater than the length between the first wrench head 101 and the first corner of the first corner link, and the first handle is located in a first wrench head screwing action plane;

as shown in fig. 2, the second wrench 200 includes a second wrench head 201, a second corner connecting rod 202 and a second handle 203, the second corner connecting rod 202 is fixedly connected between the second wrench head 201 and the second handle 203, the second corner connecting rod 202 has a second corner of 75 °, the second handle is located in a screwing action plane of the second wrench head, the second corner has the same structure and the same size of the corner as the first corner, and the second wrench head 201 and the first wrench head 101 have jaws with opposite action directions, so that the two wrenches in different directions.
