It applies elastic force under the effect of torque spring to side, can opposite direction turn back when applying external force, and torque spring stores power, external force
When cancelling, torque spring is again had an effect and is opened, under torque spring axle effect, after being connected to cutter hub under the part default situations of resistance position
End, the shrinkage pool of the connecting portion upper end of cutter hub is connected in gag lever post, and cutter hub is positioned at the middle of connector, it is to avoid at External Force Acting
Under come off from side；Simultaneously as the first Access Division is curvilinear, and the second Access Division and the curve of the first Access Division suitable mutually
Joining, the stability of this connected mode is stable；When needs dismounting cutter hub, the anti-skidding groove by resistance position part front lower portion is downward
Pulling resistance position part, torque spring is compressed, thus reserves the space of disengaging to cutter hub.
Further, described handle of a knife and connector are the integral structure of casting.The convenient casting of the structure of integral type,
Install the most firm, but clean, deposit be not as more convenient as the structure of separate type.
Further, described handle of a knife front end is provided with tapped bolt apertures, and connector rear end is provided with the externally threaded spiral shell of band
Connecing post, handle of a knife is spirally connected with connector.Demountable structure clean, deposit all easy than integral structure, use screw connection manner make
Handle of a knife is very convenient with the joint of connector.
This utility model had the beneficial effect that this utility model reasonable in design, uses interface arrangment, utilizes
Resistance position part is connected to cutter hub rear end by torque spring axle, easy accessibility, reliable and stable, and curvilinear contact surface avoids commonly
The problem that in combinative structure, cutter hub easily loosens, rocks, is particularly suited for the precise and tiny operation technique of department of obstetrics and gynecology and uses, and has well popularization
Application prospect.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the structural representation of connector described in the utility model.
Accompanying drawing 3 is the structural representation of cutter hub described in the utility model.
Accompanying drawing 4 is the structural representation of resistance position described in the utility model part.
Detailed description of the invention
Below in conjunction with the accompanying drawings 1～accompanying drawing 4 this utility model is described below.
As shown in Figure 1 to 4, this utility model includes cutter hub 1, handle of a knife 2, connector 3 and resistance position part 4, and described cutter hub 1 wraps
Including cutter head portion 1-1 and connecting portion 1-2 two parts, connecting portion 1-2 upper end is provided with two shrinkage pool 1-3, and lower end is provided with curvilinear
One Access Division 1-4, described handle of a knife 2 rear end is provided with hanging hole 6, and front end is provided with connector 3, and described connector 3 is two jig arm 3-1 groups
The structure become, between two jig arm 3-1, front end is provided with two gag lever post 3-2s of mating suitable with shrinkage pool 1-3 phase, and rear end is provided with torsion
Power spring shaft 5, described resistance position part 4 upper front end is provided with the second Access Division 4-1 that mate suitable with the first Access Division 1-4 phase, front end
Bottom is provided with anti-skidding groove 4-2, and rear end is arranged on torque spring axle 5.Torque spring axle 5 is a kind of to be built-in with torque spring
Coupling Shaft, its under the effect of torque spring to side apply elastic force, apply external force time can opposite direction turn back, torque spring store
Power, when external force is cancelled, torque spring is again had an effect and is opened, and under torque spring axle effect, is connected under part 4 default situations of resistance position
Cutter hub 1 rear end, the shrinkage pool 1-3 of the connecting portion 1-2 upper end of cutter hub 1 is connected in gag lever post 3-2, and cutter hub 1 is just being positioned at connector 3
Middle, it is to avoid to come off from side under external force；Simultaneously as the first Access Division 1-4 is curvilinear, and the second Access Division 4-
1 suitable mutually with the curve of the first Access Division 1-4 mate, and the stability of this connected mode is stably；When needs dismounting cutter hub 1, logical
Anti-skidding groove 4-2 crossing resistance position part 4 front lower portion pulls downwards resistance position part 4, and torque spring is compressed, thus reserves to cutter hub 1
The space departed from.
In the present embodiment, described handle of a knife 2 front end is provided with bolt apertures 2-1 of band female thread 2-2, and connector 3 rear end is provided with band
The post 3-3 that is spirally connected of external screw thread 3-4, handle of a knife 2 is spirally connected with connector 3.Demountable structure cleans, deposits and all hold than integral structure
Easily, screw connection manner is used to make handle of a knife 2 very convenient with the joint of connector 3.
In another the present embodiment, described handle of a knife 2 is the integral structure of casting with connector 3.The knot of integral type
The convenient casting of structure, installs the most firm, but cleans, deposits be not as more convenient as the structure of separate type.
During use, as installed cutter hub 1, being pulled downwards resistance position part 4 by anti-skidding groove 4-2, cutter hub 1 upwards embeds connection
Part 3, the shrinkage pool 1-3 of the connecting portion 1-2 upper end of cutter hub 1 rear end just embeds in gag lever post 3-2, unclamps resistance position part 4, resistance position part 4
Returning to horizontal level under the effect of torque spring axle 5, the curve of the second Access Division 4-1 and the first Access Division 1-4 matches and stings
Close, upwards withstand cutter hub 1, so that cutter hub 1 is fixedly mounted on handle of a knife 2 front end；When needs take off cutter hub 1, again by anti-
Chute stricture of vagina 4-2 pulls downwards resistance position part 4, thus takes off cutter hub 1, and this process need not use extra tool operation.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
