Description
Technical field
Medical instruments field is the utility model is related to, more particularly to a kind of soft brill spring.
Background technology
In bone surgery, when needing to fastened by screw, coordinate corresponding rise usually using electric screw driver or Pneumatic screw driver
Subheader is by screw tightening.But special circumstances can be usually run into, due to special angles and positions, in irregular and fragile people
In body structure, batch mouth on electric screw driver can not be reached directly at the screw for needing to tighten, it is difficult to tighten.
Utility model content
The utility model can be bent into any angle, match somebody with somebody mainly solving the technical problems that a kind of soft brill spring of offer
Close electric screw driver and screwdriver head, the screw that can directly can not be tightened to turning or dead angle position etc. with bottle opener fasten.
In order to solve the above technical problems, the technical scheme that the utility model uses is：A kind of soft brill spring is provided, wrapped
Include：Spring body, Screwdriver sleeve and connector, Screwdriver sleeve and connector are separately fixed at spring body both ends；The spring
Body includes internal layer spring, sublevel spring, middle level spring and outer layer spring, and sublevel spring is closely coated on internal layer spring outer wall
On, middle level spring is closely coated on sublevel spring, and outer layer spring is closely coated on the spring of middle level；The internal layer spring with time
Layer spring is oppositely oriented, and sublevel spring and middle level spring are oppositely oriented, and middle level spring and outer layer spring are oppositely oriented；The internal layer
Spring is by a spring filament winding into the pitch of internal layer spring is equal to the diameter of spring silk；Sublevel spring is coiled into side by side by two spring silks, secondary
The pitch of layer spring is equal to the double diameter of spring silk, and middle level spring is coiled into side by side by three spring silks, and the pitch of middle level spring is equal to
The three times diameter of spring silk, outer layer spring are coiled into side by side by four spring silks, and the pitch of outer layer spring is equal to four times of diameters of spring silk.
Preferably, the central diameter of the internal layer spring is less than 1.5 times of spring filament diameter.
Preferably, it is equipped with sleeve pipe on the Screwdriver sleeve and connector, the sleeve pipe of Screwdriver sleeve and connector covers respectively
At spring body both ends, the sleeve pipe of Screwdriver sleeve and connector is fastened on spring body by hydraulic means.
The beneficial effects of the utility model are：The utility model can directly can not be twisted to turning or dead angle position etc. with bottle opener
Tight screw is fastened.
Brief description of the drawings
Fig. 1 is a kind of soft main structure diagram for boring the preferred embodiment of spring one of the utility model；
Fig. 2 is a kind of shown soft cross section structure diagram for boring spring body in spring.
The mark of each part is as follows in accompanying drawing：1st, spring body；2nd, Screwdriver sleeve；3rd, connector；4th, internal layer spring；5th, it is secondary
Layer spring；6th, middle level spring；7th, outer layer spring.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
Fig. 1 and Fig. 2 are referred to, the utility model embodiment includes：
A kind of soft brill spring, including：Spring body 1, Screwdriver sleeve 2 and connector 3, Screwdriver sleeve and connector are solid respectively
It is scheduled on spring body both ends；The spring body includes internal layer spring 4, sublevel spring 5, middle level spring 6 and outer layer spring 7, secondary
Layer spring 5 is closely coated on the outer wall of internal layer spring 4, and middle level spring 6 is closely coated on sublevel spring 5, and outer layer spring 7 is close
It is coated on middle level spring 6；The internal layer spring 4 and sublevel spring 5 are oppositely oriented, sublevel spring 5 and the rotation direction phase of middle level spring 6
Instead, middle level spring 6 and outer layer spring 7 are oppositely oriented；The internal layer spring is by a spring filament winding into the pitch of internal layer spring is equal to
The diameter of spring silk；Sublevel spring is coiled into side by side by two spring silks, and the pitch of sublevel spring is equal to the double diameter of spring silk, middle level bullet
Spring is coiled into side by side by three spring silks, and the pitch of middle level spring is equal to the three times diameter of spring silk, outer layer spring by four spring silks side by side
It is coiled into, the pitch of outer layer spring is equal to four times of diameters of spring silk.The central diameter of the internal layer spring is equal to spring filament diameter.The bottle opener
It is equipped with sleeve pipe on sleeve and connector, the sleeve pipe of Screwdriver sleeve and connector is respectively fitted over spring body both ends, Screwdriver sleeve
It is fastened on the sleeve pipe of connector by hydraulic means on spring body.
The utility model can be bent into any angle, coordinate electric screw driver and screwdriver head, can be to turning or dead angle position
Fastened etc. the screw that directly can not be tightened with bottle opener, difficulty and the time of the turn of the screw can be reduced in operation.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
