Embodiment

, below will be to technology of the present utility model to make the purpose of this utility model, technical scheme and advantage clearer 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.

The torque wrench of the present utility model for being used to load and unload the operation tip of ultrasonic scaling equipment, as shown in Figures 1 to 3, including Spanner housing 1 and liner 2, the spanner housing 1 have the passage of an insertion, and the liner 2 is installed in the passage, described Interior lining offers a through hole 21, and operation tip can be worn on this through hole.

Torque wrench of the present utility model also includes resistance elastic component and clamp assemblies, wherein the resistance elastic component, is used The liner 2 is forced to be rotated relative to axis of the spanner housing 1 around the passage in providing elastic force, so that liner 2 is relative Spanner housing 1 skids, and forms idle running.Using the resistance elastic component as shell fragment 3 for example, the shell fragment 3 is arranged in described On the outer wall of lining 2, and one end of the shell fragment 3 is connected with the liner 2, the week of one end of the shell fragment 3 along the liner 2 Spring plate is formed to extension, 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 preferable scheme 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, and when domatic summit, pressure is maximum, continues to screw operation tip, shell fragment It is stupefied to cross stop, is not subjected to resistance.

As shown in figure 4, torque wrench of the present utility model also includes clamp assemblies.The clamp assemblies include cage plate 5, institute The inside that cage plate is arranged at the liner 2 is stated, sets of holes 51 are offered on the cage plate 5 and are used to clamp operation tip, the sets of holes 51 Center line overlapped with the axis of the passage.

In order to further function as fastening anticreep purpose, the clamp assembly also includes being used for the fastener 4 for clamping operation tip, The fastener 4 is arranged on the inside of the liner 2, and overlays the top of the cage plate 5.

The fastener 4 includes the outer seat 42 of back-shaped needle-like and the inner ring 41 of annular, and the inner ring 41 is arranged at the outer seat 42 inside, and the free end of the outer seat 42 and the inner ring are tangent, the diameter of the inner ring 41 is less than the width of the sets of holes Degree.

The material that the fastener uses is metal, therefore, inner ring and all flexible deformation power of outer seat.

Wherein, the wall outer surface of the liner 2 offers the card road 6 of an insertion, the fastener in the horizontal direction The Ka Daonei is arranged at, is coordinated with the Ka Dao gaps, so as to provide certain space for the elastic deformation of inner ring, outer seat.

The utility model uses clamp assemblies, can be fitted close with the stage portion of operation tip, can be picked and placeed using spanner Operation tip, directly contacted with operation tip without hand in whole process, ensure clean hygiene in medical procedure, avoid cross pollution, Realize sterile working.

When the elastic force of resistance elastic component reaches maximum, operation tip is tightened to default position by torque wrench, is further continued for revolving Twisting spanner housing makes, and resistance elastic component makes liner be slided relative to spanner housing, dallies, so as to add again to operation tip Power, screw in place, avoid operation tip tension, it is excessively loose the occurrence of.

It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses Or replace, it should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with the power The protection domain that profit requires is defined.
