Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, right below with reference to embodiment and attached drawing
The present invention is described in further details.Here, exemplary embodiment and its explanation of the invention is used to explain the present invention, but simultaneously
It is not as a limitation of the invention.
Fig. 1 and Fig. 3 shows the embodiment of the screw of the invention that safety is improved using pointed nose regracting, the screw
Including screw body 10, screw tip head 20 and elastic drive part 30.Screw body 10 includes shank of screw 11 and is arranged in screw
The head of the screw cap 12 of the tail portion of bar 11, shank of screw 11 is flat-headed, and the inside of shank of screw 11 is formed with sliding slot channel 112.
Screw tip head 20 is movably threaded through in sliding slot channel 112, and screw tip head 20 has pointed nose 21, screw tip head 20
The second of the first position on the head of shank of screw 11 and the head of the retraction shank of screw 11 of pointed nose 21 is stretched out including pointed nose 21
Position.Elastic drive part 30 is arranged between screw tip head 20 and screw body 10, and elastic drive part 30 drives screw tip
Part 20 is moved towards first position.
It applies the technical scheme of the present invention, when screw is not by external force, screw tip head 20 is by elastic drive part 30
Effect is moved towards first position, so that the pointed nose 21 of screw tip head 20 keeps stretching out the state on the head of shank of screw 11,
Production is facilitated to align screw hole when assembling.When using screw, it can press to screw cap 12, screw tip head 20 will receive screw
The power of plane 40 where hole allows screw tip head 20 to move to pointed nose 21 and retracts spiral shell so that elastic drive part 30 is pressurized
The second position on the head of nail rod 11, the pointed nose 21 of screw tip head 20 is hidden at this time, only the head tack of shank of screw 11
Shape is exposed in visible range, is carrying out after-sales service Shi Douyou safety guarantee to after-sales service personnel and user.So, originally
The screw of invention can take into account the advantages of nibbed screw and flat head screw, take into account the safety and operability of operation.
As shown in Figures 2 and 3, as a preferred embodiment, in the technical scheme of this embodiment, screw tip
It is provided with baffle portion 22 on part 20, is offered in baffle portion 22 through slot 221, is formed with and passes through slot on the tail portion of shank of screw 11
221 compatible plug divisions 111, plug division 111 is threaded through slot 221 and connect with screw cap 12.Baffle portion 22 passes through slot 221
The plug division 111 of opposite shank of screw 11 can be slided, when screw is not by external force, under the action of elastic drive part 30, and baffle portion
22 move together with the whole opposite screw body 10 of screw tip head 20 towards first position, so that screw tip head 20 moves to point
Head 21 remains the state for stretching out the head of shank of screw 11.Screw is when being assembled, in plane where alignment screw hole
After screw hole on 40, rotary screw, under the action of screw thread, screw is progressed into screw hole, the gear of screw tip head 20
Plate portion 22 is contacted with plane 40 where screw hole, continues to exert oneself, so that elastic drive part 30 is pressurized, screw tip head 20 keeps former
Position, screw body 10 continue traveling downwardly, until allowing 21 relative motion of pointed nose to be hidden into the head of shank of screw 11.
In the technical scheme of this embodiment, elastic drive part 30 is arranged between baffle portion 22 and screw cap 12.
As shown in Figures 2 and 3, as a preferred embodiment, being multiple, correspondingly plug division by slot 221
111 also to be multiple, and it is corresponding that each plug division 111 with one passes through slot 221.In this way, plug division 111 and screw cap can be made
12 connections more consolidate.More preferably, multiple plug divisions 111 surround non-close space, and elastic drive part 30 is arranged non-
In enclosure space.Elastic drive part 30 can be installed by non-close space, save the other mounting structures of redesign to pacify
Fill elastic drive part 30.As shown in Fig. 2, in the technical scheme of this embodiment, non-close space is cylindrical shape.It is corresponding,
Elastic drive part 30 is preferably cylindrical spring.As other optional embodiments, non-close space may be other shapes
Shape, such as four prism type or hexagon, elastic drive part 30 can be installed by playing.Elastic drive part 30 or elasticity
Rubber.
Under normal conditions, the hole edge of screw hole is circle, compatible, as shown in Fig. 2, in the technical solution of the present embodiment
In, baffle portion 22 is circle.In other cases, the shape of baffle portion 22 can also be suitable according to the shape on the hole edge of screw hole
Match.
It should be noted that in the inventive solutions, the top of screw cap 12 be formed with "-" type screw portion or
Cross screws portion or hexagon screws portion.It is corresponding, slotted point screwdriver or Philips screwdriver or hexagon can be used
Screwdriver screws corresponding screw.
Screw of the invention is not limited only to tapping screw, can also be used in other fasteners.Such as: fixing bolt, pin, riveting
Nail etc..
