Housing 1 and liner 2, the spanner housing 1 have the passage of an insertion, and the liner 2 is installed in the passage, the liner
On offer a through hole 21, operation tip can be worn on this through hole.
The torque wrench of the present invention also includes resistance elastic component and clamp assemblies, wherein the resistance elastic component, for carrying
Ammunition feed power forces axis of the liner 2 relative to the spanner housing 1 around the passage to rotate, so that liner 2 is with respect to spanner
Housing 1 skids, and forms idle running.By shell fragment 3 of the resistance elastic component for example, the shell fragment 3 is arranged in the liner 2
On outer wall, and one end of the shell fragment 3 is connected with the liner 2, and the circumference of one end of the shell fragment 3 along the liner 2 is prolonged
Stretch to form spring plate, spring plate has free termination.
Shell fragment groove is offered on the liner 2, the shell fragment 3 is arranged in the shell fragment groove, and scheme preferably is shell fragment
With internal lining integral, i.e., in lining fluting, the circumferentially extending from the end face of groove along liner 2 forms shell fragment, realizes shell fragment
One end is connected with shell fragment groove, in addition the hanging structure in three faces, so as to ensure that shell fragment 3 has enough radial directions in shell fragment groove
On deformation space.
The free termination has an inclined-plane, and the high point on the inclined-plane protrudes from the spring plate, and the height on the inclined-plane
Depth of the degree more than the shell fragment groove.
In order to coordinate with shell fragment 3, multiple stops stupefied 11, multiple stops are convexly equipped with the inwall of the spanner housing 1
The axial direction of passage is uniformly distributed described in stupefied 11 ring, and each stupefied 11 edge of stop is the axially arranged of the passage.
The vertical section of each stop stupefied 11 is right-angled trapezium, that is, be respectively provided with one it is domatic, it is described domatic to be pulled with described
The angle of hand housing 1 is acute angle, the axis of the passage with it is described domatic parallel.
In actual use, the inclined-plane of the free termination of shell fragment 3 is resisted against on stupefied domatic of stop, screws operation tip
When, shell fragment is pressurized, and its free termination is climbed along domatic, when domatic summit, and pressure is maximum, continues to screw operation tip, shell fragment
Cross stop stupefied, be not subjected to resistance.
As shown in figure 4, the torque wrench of the present invention also includes clamp assemblies.The clamp assemblies include cage plate 5, described
Cage plate, which is arranged on the inside of the liner 2, the cage plate 5, offers set hole 51 for clamping operation tip, the set hole 51
