Description
Technical field
The present invention relates to a kind of cover cap inboard is provided with to piece; Support and promote the clipping block of mesh ratchet gear both sides when piece can rotate with the relative pawl seat of cover cap; Utilize recessing or meshing of clipping block, make bottle opener switch the device of pulling direction, relate in particular to a kind of ratchet screw reversing arrangement.
Background technology
Present ratchet screw is just like TaiWan, China letters patent book number M255766 number " screwdriver structure improvement "; Its structure generally is in a body, to offer a containing hole and radial two storage tanks; This containing hole is the shape that communicates with this two storage tank; This two storage tank is to be an angle each other, and each storage tank tool two parallel edges is established a catch groove in the containing hole front end;
One ratchet is provided with circular tooth part, and the circular tooth part of ratchet can be placed in the containing hole; Two system teeth form the clamping tooth that can be meshed with circular tooth part in a side, protrude out a projection in the system tooth tip, differ from a side tool card end of clamping tooth;
Two elastomers are can respectively be sleeved on the card end of two system teeth, and two system teeth and two elastomers are to be placed in two storage tanks; One loam cake is to be covered on this externally to establish perforation in front end, offers a groove in inside, on groove, is convexly equipped with projection; One catch can be placed in the catch groove of body, and ratchet and two system teeth promptly receive the restriction of catch and do not drop out external;
During this ratchet screw action; Be that loam cake is threaded to a certain angle (for example to right rotation), then projection the right makes the clamping tooth of right system tooth break away from the circular tooth part in ratchet promptly by supporting the projection of right system tooth; Clockwise can a left side system tooth mesh ratchet gear during turn body and produce and pull effect; The turn body is then made the relative ratchet generation of tooth jumping tooth in a left side counterclockwise, and body then returns back to turn position originally whereby, and so clockwise, counterclockwise turn body can be reached the effect of back and forth pulling.
It is to stem from the projection that the projection of loam cake compels to resist tooth that aforementioned ratchet screw switches the effect of pulling direction, make projection compeled to the system tooth recess ratchet because of the rotation of loam cake is pushed, only should the system tooth when producing; Projection on it need can moulding through extra processing; And in the use, the projection of system tooth is little because of thin thickness, volume, so structure is also relatively poor relatively; Permanent use easily worn and torn impairedly because of the pushing and pressing of loam cake projection, even causes ratchet screw to lose switching the function of pulling direction.
The inventor produces inconvenience in view of the projection of this kind ratchet screw system tooth has the additional processing of need, and fragile structure, and the shortcoming that easy abrasion damage is so decision is set about improving.
Summary of the invention
Technical problem underlying to be solved by this invention is; Overcome the above-mentioned defective that prior art exists, and a kind of ratchet screw reversing arrangement is provided, improve the convenience of producing; Effectively reduce abrasion; Can grow the switching of guarantor's ratchet screw and pull the normal of direction function, increase the smooth and easy degree of clipping block advance and retreat, and can save the material cost of putting wheel seat.
