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.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of novel hydraulic torque wrench, including hydraulic
Cylinder 1, the right end of the piston rod 2 of the hydraulic cylinder 1 are connected with pin shaft A3, and the pin shaft A3 passes through 5 rotation of shift fork 4 and transmission chaste tree wheel
Connection, the transmission chaste tree take turns and are socketed with drive shaft 6 in 5, are provided with torque spring 7 between the drive shaft 6 and transmission chaste tree wheel 5,
The top of the drive shaft 6, which is plugged with, adjusts screw 8, and the top of the drive shaft 6 is provided with Spring retainer 9, the transmission
The bottom end of chaste tree wheel 5 is connected with ut socket 10, is provided with gasket 11, the liquid between the ut socket 10 and transmission chaste tree wheel 5
The one end of cylinder pressure 1 far from piston rod 2 is hinged with counter-force arm 13, the described one end of counter-force arm 13 far from hydraulic cylinder 1 by pin shaft B12
It being connect with transmission chaste tree wheel 5, the surface of the hydraulic cylinder 1 is equipped with oil mirror 14, and 1 upper end of hydraulic cylinder is connected with rotary body 15,
It is provided with oil inlet fast interface and fuel-displaced fast interface on the rotary body 15, oil inlet and the Extraction rate of oil cylinder is accelerated, mentions
