Abstract
The utility model relates to the technical field of medical devices, in particular to a torsion handle. A base of the torsion handle is arranged in the handle. A changing push rod is arranged in the handle and clutches are arranged on the two sides of the changing push rod. Belleville springs are arranged at the front ends of the clutches. The front ends of the belleville springs are provided with adjusting top threads and adjusting fixation top threads. The adjusting top threads and the adjusting fixation top threads are fixed in the handle through hexagon socket top threads. The front end of the handle is provided with handle caps. The two sides of the change push rod are provided with O-shaped sealing rings. The front end of the change push rod is provided with a threaded pressing disc and a core sleeve. Pull sleeves are arranged outside the threaded pressing disc and the core sleeve. Compression springs are arranged between the threaded pressing disc and the core sleeve. The changing push rod is fixed through a round pin. The handheld part of the torsion handle can meet the shape of an adult man and can smoothly provide rotation torsion. The O-shaped sealing rings are used at the tail part of the torsion handle so that the sealing performance of the torsion handle is good. Low-rotation abrasion is less than 200 times and the torque is kept within the range of 0.7 N.m to 0.9 N.m after assembly.
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 handle and base, base is placed in handle, also be provided with and change push rod in handle, change the push rod both sides and be provided with clutch, front end at clutch is provided with butterfly spring, front end at butterfly spring is provided with the adjusting jackscrew and regulates fixedly jackscrew, and regulate jackscrew and regulate fixedly jackscrew and be fixed in handle, fixed by interior hexagonal jackscrew, the front end of handle is provided with handle cap, change the push rod both sides and be provided with the O RunddichtringO, the front end that changes push rod is provided with screw thread platen and core retainer plate, be provided with and help pull a cart outside screw thread platen and core retainer plate, be provided with stage clip between screw thread platen and core retainer plate, changing push rod fixes by straight pin.
According to another embodiment of the invention, comprise that further the handle outside is provided with jackscrew, and the jackscrew place is provided with O RunddichtringO two.
According to another embodiment of the invention, comprise that further handle cap one end place is provided with O type circle one.
According to another embodiment of the invention, further comprise in core retainer plate and be provided with steel ball.
The beneficial effects of the utility model are: the handle grip part of this torque handle, can meet middle aged man's hand shape size, and can provide smoothly rotary torsion, afterbody uses O type circle to make its favorable sealing property, and hanging down goes round and round a millstone closes and is no less than 200 times, guarantees to assemble rear moment of torsion 0.7-0.9N.m.
