Scheme is described in detail.Obviously, described embodiment is only the utility model part of the embodiment, rather than all
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not before creative work is made
Resulting all other embodiment is put, belongs to the scope that the utility model is protected.
As shown in Figure 1, 2, the torque wrench of the present utility model for being used to load and unload ultrasonic scaling equipment operation tip, including spanner
Housing 1, liner 2, resistance elastic component and clamp assemblies, the spanner housing have the passage of insertion, and the liner is installed on institute
State in passage, offer through hole at the top of the liner, operation tip can be worn on this through hole.
The resistance elastic component of the present utility model forces the liner relative to the spanner housing for providing elastic force
Axis around the passage rotates, so that liner 2 skids with respect to spanner housing 1, forms idle running；Using the resistance elastic component as
Spring distance explanation, the spring 3 are set on the liner 2.One end bending of the spring 3 is upwardly formed insertion section 31,
The 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, institute on the inner surface of the spanner housing 1
Convex edge 11 is stated along the circumferentially disposed of the spanner housing 1, i.e., the inner ring of spanner housing 1 is inwardly projecting forms a narrow side.It is described
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 convex edge.Spring 3
Insertion section 31 pass through a positioning hole 12, i.e., this end of spring is fixed together with spanner housing.The positioning hole
Quantity be preferably four, 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 utility model is combined into, and groove just engages with convex edge,
The width of groove is slightly larger than the width of convex edge, after both engage, liner can not only be arranged on spanner housing, and have
There is certain frictional force between both contact surfaces.A pair of active forces of formation of the elastic force of this frictional force and spring and reaction
Power, 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
During elastic force, spanner housing rotates relative to liner, operation tip no longer stress, screws in place.
In torque wrench structure of the present utility model, the clamp assemblies include cage plate 5 and fastener 4.The cage plate 5 is set

Line overlaps with the axis of the passage of the spanner housing 1.The shape of sets of holes 51 and the shape of operation tip pedestal match, Ke Yishi
Slotted hole or polygonal hole, and the size of sets of holes 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, after operation tip passes through sets of holes, 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, after the base portion of operation tip gets into inner ring, not only receive the elastic clamping of material in itself, and existed by arriving
The elastic deformation restoring force of outer seat, this restoring force point to the center of circle of inner ring.
For the ease of installing this fastener, the card road 6 of an insertion is offered in 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 as to be carried for the elastic deformation of inner ring, outer seat
For certain space.
Material used by for torque wrench of the present utility model, wherein, the material that the spanner housing uses is modeling
Material, the liner can also use plastic material.
