Abstract
The invention discloses a ratchet wrench which comprises a handle and a head portion. The head portion is arranged at one end of the handle. A first through hole is formed in the center of the head portion. A plurality of first grooves are evenly distributed in the inner wall of the first through hole. A spring is arranged in each first groove. A clamping key is arranged on the upper portion of each spring. Each clamping key comprises two opposite and parallel vertical faces, the tops of the clamping keys are in an arc shape, and the central angles of the arcs of the clamping keys are not larger than 90 degrees. One end of the top of each clamping key is tangent to one vertical face of the corresponding clamping key, and the other end of the top of each clamping key is arranged on the other vertical face of the corresponding clamping key. A valve element is arranged in the first through hole. A hexagonal through hole is formed in the center of the valve element. A plurality of second grooves are evenly distributed in the outer circumference of the valve element, and the bottoms of the second grooves and the tops of the clamping keys are formed consistently so that the clamping keys can be inserted into the clamping grooves. After a nut is clamped on one face of the ratchet wrench, the nut can be continuously screwed down. When the nut is clamped after the wrench is turned over, the nut can be unscrewed continuously.
Description
Technical field
The present invention relates to a kind of improvement of spanner, particularly a kind of ratchet spanner that can screw continuously or unscrew by clamped one time nut nut.
Background technology
Current spanner, comprises handle; The front portion of described handle is provided with driving end; Described driving end, comprises the first tight lock part, the second tight lock part; Distance between described the first tight lock part and the second tight lock part can regulate, so that it adapts to the nut of different specifications; This spanner in use, first regulate the distance locking nut between the first tight lock part, the second tight lock part, rotary handle again, nut screwed or unscrew, but again when rotating nut, must first driving end be cancelled from nut, regulate after angle, again be inserted in nut, ability rotating nut, thereby use more loaded down with trivial details; Particularly, in the narrower and small situation of the usage space of nut, this spanner may be put to good use not open, and cannot work.For this reason, we have researched and developed a kind of ratchet spanner that can be screwed continuously or unscrew by clamped one time nut nut.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: proposed a kind of ratchet spanner that can screw continuously or unscrew by clamped one time nut nut.
Technical solution of the present invention is achieved in that ratchet spanner, comprises handle, head; Described head is arranged on one end of handle; The center of described head is provided with the first through hole; On the inwall of described the first through hole, be evenly equipped with multiple the first grooves; In each the first groove, be provided with spring; The top of every spring is provided with card key; Described card key includes two relatively and the vertical plane being parallel to each other, and it is circular-arc that the top of described card key becomes, and its center of arc angle is not more than 90 degree; The one end at the top of described card key and the vertical plane of card key are tangent, and the other end is arranged on another vertical plane of card key; In described the first through hole, be provided with spool; The center of described spool is provided with hexagon through hole; On the excircle of described spool, be evenly equipped with multiple the second grooves, it is consistent that the bottom of described the second groove and the top of card key form, so that card key can be inserted in the second groove.
Preferably, the center of the bottom of described the first groove is provided with the first projection; The bottom that described the first projection is inserted spring.
Preferably, the bottom of described card key is provided with the second projection; The top that described the second projection is inserted spring.
Preferably, the both sides of described head are respectively arranged with cover plate; Described cover plate is screwed on head.
Preferably, the first groove arranging on the inwall of the first through hole has 6; The second groove arranging on the excircle of spool has 6.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Can continuous fastening nut after a clamping nut of ratchet spanner of the present invention, and by clamping nut again after spanner upset, can unscrew continuously nut; The present invention is simple in structure, and practicality is easy to operate.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The front view that accompanying drawing 1 is ratchet spanner of the present invention;
Cutaway view when accompanying drawing 2 is ratchet spanner tight condition of the present invention;
Cutaway view when accompanying drawing 3 send state for ratchet spanner of the present invention is stubborn;
Wherein: 1, handle; 2, head; 3, the first through hole; 4, the first groove; 5, the first projection; 6, spring; 7, card key; 8, the second projection; 9, spool; 10, the second groove; 11, hexagon through hole; 12, cover plate; 13, screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
As accompanying drawing 1-3 is depicted as ratchet spanner of the present invention, comprise handle 1, head 2; Described head 2 is arranged on one end of handle 1; The center of described head is provided with the first through hole 3; On the inwall of described the first through hole 3, be evenly equipped with multiple the first grooves 4; In the present embodiment, described the first groove 4 has 6; The center of the bottom of each the first groove 4 is provided with the first projection 5; In each the first groove 4, be provided with the bottom of spring 6, described the first projection 5 insertion springs 6; The top of every spring 6 is provided with card key 7; Described card key 7 includes two relatively and the vertical plane being parallel to each other, and it is circular-arc that the top of described card key 7 becomes, and its center of arc angle is not more than 90 degree; The vertical plane of the one end at the top of described card key 7 and card key 7 is tangent, and the other end is arranged on another vertical plane of card key 7; The bottom of described card key 7 is provided with the second projection 8; The top that described the second projection 8 is inserted spring 6; In described the first through hole 3, be provided with spool 9; The center of described spool 9 is provided with hexagon through hole 11; On the excircle of described spool 9, be evenly equipped with multiple the second grooves 10, in the present embodiment, the second groove 10 arranging on the excircle of spool 9 has 6; It is consistent that the bottom of described the second groove 10 and the top of card key 7 form, so that card key 7 can be inserted in the second groove; The both sides of described head 2 are respectively arranged with cover plate 12; Described cover plate 12 use screws 13 are fixed on head 2.
