Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention. The structures or processes not specifically mentioned are conventional in the art.

Example 1. A pipeline maintenance special-shaped wrench comprises a sleeve 1, wherein the inside of the sleeve 1 is connected with a driving shaft 3 through a first bearing 2, one end of the driving shaft 3 is connected with a handle 4, the other end of the driving shaft is connected with a first sector gear 5, the first sector gear 5 is meshed with a second sector gear 6, the second sector gear 6 is connected with a transmission shaft 7, the upper end of the transmission shaft 7 is sleeved with a second bearing 8, the second bearing 8 is connected with a mounting plate 9, the mounting plate 9 is connected with a mounting seat 10, the mounting seat 10 is connected with the sleeve 1, the lower end of the transmission shaft 7 is movably connected with a rotating seat 11, and a nut groove 12.

The utility model discloses a use method and theory of operation: when the tool is used, the rotating seat 11 with the applicable nut groove 12 is selected for operation, the rotating seat 11 is sleeved on a bolt or a nut needing to rotate, namely the bolt or the nut is put into the nut groove 12, then the sleeve 1 can be fixed by depending on the left wall and the right wall in a narrow space or by hands, and then the handle 4 is rotated. When specific rotatory handle 4, it can drive shaft 3 and rotate, drive shaft 3 stably rotates under the effect of bearing 2, then rotate through fan-shaped gear 5 of its tip, fan-shaped gear 5 drives fan-shaped gear two 6 and rotates, and meanwhile fan-shaped gear two 6 drive transmission shaft 7, transmission shaft 7 stably rotates under the effect of two 8 of bearing, transmission shaft 7 drives and rotates seat 11 and rotates, bolt and nut will be followed and rotate seat 11 and rotate, can realize the operation of twisting of bolt and nut.
