Problems solved by technology
[0002] Transmission line maintenance work is an important task to ensure the safe operation of transmission lines. Line maintenance work is the work of overhauling transmission towers and ground wires at high altitudes. Especially in recent years, due to the gradual elimination of line cement poles, the following For the angle steel towers connected by bolts, there are as few as one thousand bolts and as many as thousands of bolts for each base iron tower, which must be tightened regularly. If only one wrench is used to tighten or loosen the nuts during the bolt tightening process, At this time, it often happens that the nut and the bolt rotate at the same time, which affects the maintenance work. In order to solve this problem, the operator needs to hold two wrenches for fastening operations, and the wrench often falls. It is not very convenient to work with two wrenches

Embodiment Construction
[0027] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.
[0028] like Figure 1-3 As shown, a wrench assembly includes a set piece 1; the set piece 1 includes a cylindrical upper part, a cylindrical lower part and a connecting piece; the upper part and the lower part are separated because some bolts and nuts are separated The structure to be fastened has a certain thickness and width. In order to reserve a certain space to bypass the structure, the upper part and the lower part are separated, and then connected by a connecting piece, and the connecting piece is preferably an arc-shaped metal sheet; The arc-shaped metal sheets of the upper and lower parts have certain elasticity, and the upper part is provided with an upper wrench installation slot 2 and an upper wrench rotation slot 3; the lower part is provided with a lower wrench installation slot 4 and a lower wrench rotation slot 5 ; The u...

The invention provides a wrench assembling unit, a combined wrench and a using method thereof. The wrench assembling unit comprises a sleeving piece. The sleeving part comprises a cylindrical upper part, a cylindrical lower part and a connecting piece; and the upper part and the lower part are separated and connected by the connecting piece which is preferably an arc-shaped metal sheet. The combined spanner comprises the spanner assembling unit, an upper spanner clamped in a upper spanner rotating groove and a lower spanner clamped in a lower spanner rotating groove. According to the wrench assembling unit, the combined wrench and the using method thereof, the two wrenches are combined into a whole by using the wrench assembling unit, the danger of falling from high altitude is avoided, the maintenance work of maintenance personnel is greatly facilitated, and efficiency and practicality are achieved.
