The bottom of described elevating lever is provided with tripod.Described elevating lever is cylindrical epoxy rods. The often joint sleeve pipe of described elevating lever is provided with spring wedge, and when sleeve lift to position, sleeve pipe is positioned by spring wedge spring, shrinks and elongation when being pressed into spring wedge elevating lever. Described opening bracing wire forms four direction bracing wires with the bottom of two tong arms after being connected with elevating lever again after being connected successively.
The method have the advantages that after have employed above technical scheme, the present invention can reduce power off time, improves work efficiency, saves engineering cost. The present invention is provided with pincerlike Overline ring, it not only reduce frictional force and make new frame wire safety, quickly through crossing frame, it is prevented that new frame wire crosses friction injury span line or barrier during line, and easy to operate, improve work efficiency, improve the reliability of power supply simultaneously. Elevating lever of the present invention is cylindrical epoxy rods, and the mechanical property that so not only can improve elevating lever is high, has excellent electrical insulating property, and light weight, it is simple to carrying, cylindrical windward side is little simultaneously, line ability, the good stability excessively of bigger wind load and wire can be born. The volume of the present invention is little, solves transport and takes up an area the problem that young crops reparation is high. The wire of present invention jaw when passing through pincerlike Overline ring is closed, it is prevented that wire spring decylization, can effectively be separated by Overline ring by opening bracing wire when stringing, makes wire leave Overline ring and goes up to the air, and unclamps bracing wire and crosses line and have spring contraction Natural closure. Pincer Overline ring of the present invention is provided with slip pipe, so can be reduced frictional force and make new frame wire safety, quickly through crossing frame. The separately installed spring wedge of often joint inside pipe casing of the present invention, sleeve lift is to fixed position, and spring wedge ejects, and presses in spring cover of wedge pipe, according to field requirement lift adjustment. Described opening bracing wire of the present invention forms four direction bracing wires after being connected with elevating lever after being connected with the bottom of two tong arms successively again, so can be fixed by bracing wire, be provided with tripod in the bottom of elevating lever, so can remaining stable for property.
