Described location gear ring is rounded, its in circular inwall be provided with positioning tooth mouth；
Described pinch bar is cylinder, its in cylindrical one end be connected with driving end, the other end is fixed with
Contiguous block, constant torque wrench is provided with cantankerousization strengthening protruding, right projection and anti-slip veins, and described anti-slip veins is netted, is positioned at and pulls
Hands handle end, described cantankerousization strengthening protruding, right projection is divided into the left and right sides of constant torque wrench, and protrudes from and determine moment of torsion
Spanner outer surface, cantankerousization is protruding from contiguous block outer wall, through pinch bar, extends to driving end lower end, and right strengthening is protruding from pulling
Hands middle handle, extends to driving end lower end, and described contiguous block is hemisphere, which is provided with connecting screw hole；
Being provided with dismountable bolt adapter block in the gear ring of described location, described bolt adapter block is rounded, its in circle
The outer wall of shape is provided with positioning tooth, described positioning tooth and positioning tooth mouth corresponding matching, and the center of bolt adapter block is for pulling mouth；
Further, described driving end is provided with the first pin hole and latch, and the periphery of described bolt adapter block is provided with
Two pin holes, described latch and the first pin hole, the second pin hole corresponding matching；
Further, described contiguous block includes joint face, and the axis of described connecting screw hole is vertical with joint face, connecting screw hole
The axis institute of axis and pinch bar angled be 40 ° ~ 45 ° for α, described α.
The beneficial effects of the utility model are:
A kind of bus tie constant torque wrench that the utility model proposes, the single ended bolt for bus tie fastens
Purpose designs, and its simple in construction is reasonable in design, and including driving end and pinch bar, bolt adapter block is installed at the middle part of driving end,
Bolt adapter block coordinates location by positioning tooth and positioning tooth mouth, is realizing fixing by latch, and arrange cantankerousization projection,
Right strengthening projection and contiguous block, the connecting screw hole that contiguous block is arranged, be used for connecting extension rod, and the work reducing fastening bolt is strong
Degree, cantankerousization is protruding extends constant torque wrench first and last, and right strengthening is protruding extends to driving end lower end in the middle part of pinch bar,
While ensureing certain gripping comfort level, improve the intensity of constant torque wrench.
