Body, the spanner housing includes the upper shell 10 and lower house 13 being connected with each other, and the upper shell has the passage of insertion, described
The top of lower house is provided with liner 2, and the liner is installed in the passage, and through hole 21 is offered at the top of the liner, works
Point can be worn on this through hole.
The resistance elastic component of the present invention forces the liner relative to the spanner housing around institute for providing elastic force
The axis for stating passage is rotated, and is skidded so that liner 2 is relative with upper shell, is formed idle running.Using the resistance elastic component as spring
Distance explanation, the spring 3 is set in the top of lower house.One end bending of the spring 3 is upwardly formed insertion section 31, described
Insertion section 31 and the diameter parallel of the spring 3, insertion section 31 can be fixed with spanner housing 3.
The fixed form of spring 3 and spanner housing 1 is：There is a circle convex edge 11 on the inner surface of the upper shell, it is described
Convex edge 11 is circumferentially disposed along the spanner housing 1, i.e., the inner ring of spanner housing 1 is inwardly projecting forms a narrow side.It is described convex
At least one positioning hole 12, the diameter parallel of the axis of positioning hole 12 and the passage of spanner housing 1 are offered on edge.Spring 3
This end of spring and spanner housing are fixed together by insertion section 31 through a positioning hole 12.The positioning hole
Quantity is preferably four, and four positioning holes are to be distributed on the convex edge.
In order to coordinate with spanner housing, the outer surface of the liner is provided with a circle groove, and the groove is along the liner
Circumferentially disposed, the groove is engaged with the convex edge, and signified the matching somebody with somebody of the present invention is combined into, and groove just engages with convex edge, groove
Width be slightly larger than convex edge width, both engage after, can not only make liner be arranged on spanner housing on, and with both
Contact surface between have certain frictional force.A pair of active forces of formation and reaction force of the elastic force of this frictional force and spring,
When frictional force is more than spring force, spanner housing is synchronous with liner, and operation tip can be tightened；When frictional force is less than spring force
When, spanner housing is rotated relative to liner, and operation tip no longer stress is screwed in place.
Relative to above-mentioned groove and the fit system of convex edge, present invention additionally comprises a kind of structure, by upper shell with
The corresponding structure of housing, reaches that cooperation spring completes limiter, as shown in Figure 3：Upper shell 10 is hollow barrel, and lower house 13 is
Convex shape, the top that lower house 13 is protruded is arranged in upper shell passage.The lower edge of the upper shell is to the upper shell
Inner horizontal extends to form edge 7, and the circumference of the top of the outer wall of lower house 13 along the lower house is arranged with a circle neck,
The edge is inserted in the neck.Along the circle slot 8 that is circumferentially with of the convex edge on the lower surface of the convex edge, it is described under
The top of the side wall of housing is inserted in the slot.
Above-described edge and side wall and the cooperation of slot of neck cooperation, or lower house, principle and groove convex edge
Between cooperation it is identical, be for providing certain frictional force resisting the elastic force of spring.Therefore, three's formula mode can be with
Permutation and combination is optionally carried out as needed.
In the torque wrench structure of the present invention, the clamp assemblies include cage plate 5 and fastener 4.The cage plate 5 is arranged at
Offer the set hole 51 for wearing operation tip on the inside of the liner 2, the cage plate 5, the center line in the set hole 51 with
The axis of the passage of the spanner housing 1 is overlapped.The shape and the shape of operation tip pedestal for covering hole 51 match, and can be oval
Hole or polygonal hole, and the size for covering hole is slightly larger than the size of operation tip pedestal, so as to facilitate operation tip to pass through.
Fastener 4 in the clamp assemblies, for clamping operation tip, it uses the metal with certain elasticity to be made.
Fastener overlays the top of the cage plate, and operation tip is passed through behind set hole, you can clamped by fastener.
The concrete shape of the fastener is, including outer seat is back-shaped needle-like, and inside one annulus of connection does inner ring.Inner ring
With the end of the outer seat with it is tangent.The inner ring is the circumscribed circle of operation tip base portion.Inner ring and outer seat are metal material, this tool
There is certain elasticity, the base portion of operation tip is got into after inner ring, not only receive the elastic clamping of material in itself, and existed by arrival
The elastic deformation restoring force of outer seat, this restoring force points to the center of circle of inner ring.
For the ease of installing the card road 6 for offering an insertion on this fastener, the side wall of the liner in the horizontal direction,
The fastener 4 is arranged in the card road 6, and is coordinated with the Ka Dao gaps, so that the elastic deformation for inner ring, outer seat is carried
For certain space.
The material used for the torque wrench of the present invention, wherein, the material that the spanner housing is used is plastics, institute
Plastic material can also be used by stating liner.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
