In the prior art, there is no multi-type bolt fastening insulating rod with a large range of use and a large labor-saving torque.

Contents of the invention

The purpose of this utility model is to overcome the above-mentioned shortcomings, and propose a multi-type bolt fastening insulating rod with large application range, labor saving and large torque.

The utility model is realized by following method.

Multi-type bolt fastening insulating rods have round tubular insulating rods, the lower end of the insulating rod is connected with a cylindrical rotating input head, and the lower end of the insulating rod is connected with a cylindrical rotating output head. On the same straight line, the lower end of the input head has a hexagonal prism section, the lower end of the input head has a quadrangular prism groove, the upper end of the input head has a circular groove matching the round tube of the insulating rod, the circular groove and the quadrangular prism The axis of the groove and the axis of the cylinder of the input head are on the same straight line, the input head has staggered vertical upper and lower radial pin holes, the upper end of the output head has a square prism plug, and the lower end of the output head has a round tube with an insulating rod Matching ring grooves, the axes of the ring grooves and quadrangular prism grooves are on the same line as the axis of the insulating rod, the output head has staggered vertical upper and lower radial pin holes, and the lower end of the insulating rod is inserted into the input head In the circular groove at the upper end, pin rods are inserted into the upper and lower radial pin holes on the input head, the upper end of the insulating rod is inserted into the circular groove at the lower end of the output head, and the upper and lower radial pin holes on the input head A pin rod is inserted inside.

The utility model needs to be used in conjunction with an electric wrench. The electric wrench has an electric wrench host and a plurality of matching sleeve plates of different specifications. The electric wrench host has a quadrangular prism-shaped rotating output head. The prismatic rotary output head matches the quadrangular prism socket, and the other end of the sleeve plate has a hexagonal screw hole matched with the hexagonal nut.

The quadrangular prism groove of the input head of the utility model cooperates with the quadrangular prism rotating output head of the electric wrench host, and the quadrangular prism plug on the upper end of the output head matches the prismatic jack at one end of the electric wrench sleeve plate.

When in use, take a sleeve plate, put the square prism jack of the sleeve plate on the square prism plug at the upper end of the output head of the utility model, lift the utility model, and put the hexagonal screw hole of the sleeve plate on the Put the square prism-shaped rotary output head of the electric wrench host into the square prism-shaped groove of the input head on the hexagonal bolts on the electric device and equipment at a high place, start the electric wrench main unit, drive the utility model to rotate, and realize tightening or turning Loosen bolts on electrical installations and equipment at heights. The utility model can also be driven by a manual wrench to rotate. When the manual wrench is used to drive the rotation, the jaws of the manual wrench are stuck on the hexagonal column-shaped section at the lower end of the input head of the utility model, and the manual wrench is rotated to realize tightening or unscrewing the high power. Bolts on fixtures and equipment.

The square prismatic plug at the upper end of the output head of the utility model can be connected to sleeve plates of various specifications and sizes in the electric wrench, and bolts of various specifications and sizes can be tightened or unscrewed, and the application range is large; the utility model can be used with the electric wrench The main engine and manual wrench drive the rotation, which saves labor and has large torque.

Below in conjunction with accompanying drawing, the utility model is described further.
