Abstract
The utility model relates to the technical field of medical equipment, in particular to a torque handle. The torque handle comprises a pipe plug. The pipe plug is connected to one end of a rear housing, the other end of the rear housing is connected with a front plug, an O-shaped sealing ring is further arranged, silicon rubber is arranged outside the rear housing, a bearing core is arranged at the front end of the rear housing, a mandrel is arranged between the rear housing and the bearing core and sleeved with a butterfly elastic piece, a sliding clutch and a fixed clutch, one end of the butterfly elastic piece is connected with an adjusting nut and a sliding pad, the other end of the butterfly elastic piece is connected with the sliding clutch which is connected with the fixed clutch, a sliding sleeve plug is arranged at the front end of the mandrel and sleeved with sliding sleeves, ports are formed between the sliding sleeves, and steel balls are arranged in the ports and between the sliding sleeves. The torque handle is simple in structure, low rotating running-in can be conducted no less than 200 times, the torque is kept within the range from 1.4N.m to 1.6N.m after the torque handle is assembled, the application range is wide, and working efficiency can be improved.
Description
Technical field
The utility model relates to a kind of handle, relates in particular to a kind of torque handle.
Background technology
In prior art, medical field is often used torque handle, and torque handle after most importantly performance indications are used repeatedly torsion deviation can or can not occur, can or can not lose efficacy, this is the index that we weigh a torque handle quality.The torque range of existing torque handle is little, can't meet the need of market.
Summary of the invention
The technical problems to be solved in the utility model is: the torque range of existing torque handle is little, can't meet the need of market, and a kind of torque handle is provided.
in order to overcome the defect that exists in background technology, the technical scheme that its technical problem that solves the utility model adopts is: this torque handle comprises plug, plug connects back cover one end, plug before the other end of back cover connects, and be provided with the O RunddichtringO, be provided with Silicone Rubber outside back cover, the front end of described back cover is provided with and holds core, at back cover with hold between core and be provided with mandrel, be arranged with the butterfly shell fragment on mandrel, slip-clutch and fixed clutch, one end of butterfly shell fragment connects adjusting nut and skidding, the other end connects slip-clutch, slip-clutch is connected and fixed clutch, the front end of described mandrel is provided with the sliding sleeve plug, the outer sheathed slip cap of sliding sleeve plug, be provided with interface between slip cap, between slip cap, be provided with steel ball in interface.
According to another embodiment of the invention, comprise that further described slip-clutch fixes by pin.
According to another embodiment of the invention, further comprise between described interface and slip cap and be provided with spring.
The beneficial effects of the utility model are: this torque handle simple in structure, and can hang down goes round and round a millstone closes and is no less than 200 times, guarantees to assemble rear moment of torsion 1.4-1.6N.m, and the scope of application is extensive, can increase work efficiency.
