Preferably, one end that described adjusting screw(rod) is connected with the reaction arm of force is also provided with bulb.Described bulb can reduce the anti-stressed impact on adjusting screw(rod) distortion, bending and destruction in the time regulating the reaction arm of force, when turn, can better reduce friction.
Preferably, the bottom surface of the described reaction arm of force is provided with twill annular knurl, in the time affected by radial load for the displacement between anti-spline spanner and support member and the impact bringing.
Preferably, described bearing pin and pull between body and be also provided with axle jump ring, described axle is arranged in the axial trough of bearing pin 8 with jump ring.
One side of described working head is provided with the draw-in groove supporting with tight locking button, and opposite side is provided with the hook supporting with locating shaft.
The bolt hole of described working head is hexagon hole, and bolt hole has the specification of different size according to the specification difference of bolt, nut.
The described reaction arm of force and handle can be realized 0 degree by adjusting screw(rod) and change to the angle of 45 degree.
Compared to the prior art, beneficial effect of the present invention:
The present invention is Fully-mechanized, without hydraulic pressure; Retaining mechanism is simple, easily discharges fast changeable working head; Have easy handle and the reaction arm of force, can solve the problem of nut transfer, the old-fashioned spanner before being different from need to be used mat.
