Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of torque wrench, including the piston rod in counter-force arm support 1, driver plate 2, cylinder body 3 and cylinder body 3
4,3 tail portion of cylinder body is connected in the projection seat of 1 tail end of counter-force arm support by pin shaft, and 1 front end of counter-force arm support is equipped with
U-typed opening, the driver plate 2 are located in U-typed opening, and 2 bottom of driver plate is equipped with through-hole, are equipped with ratchet in the through-hole
5,5 side of ratchet is equipped between pawl 6, ratchet 5 and the pawl 6 to match and is connected by ratchet, leads among the ratchet 5
It crosses ratchet and is connected with drive shaft 7, described 7 one end of drive shaft passes through U-typed opening and is connected with square column 8, the piston rod 4
Extension end is connected with connecting plate 9, and the connecting plate 9 is fixedly connected by bolt with driver plate 2, in this embodiment, in order to guarantee
Reliability when transmission, 9 one end of connecting plate are open equipped with " U ", and driver plate 2 is placed in " U " opening of connecting plate 9, and driver plate 2 is logical
Bolt is crossed to be fixedly connected in " U " opening；Connector sleeve 10 is socketed on the outside of the cylinder body 3, the connector sleeve 10 is solid by screw
