Abstract
The invention relates to an improved ratchet wheel wrench, which is characterized in that a reversing part of a ratchet wheel wrench comprises a selector lever with a connecting rod; a stopping part is arranged at the end part of the connecting rod; a braking part of the ratchet wheel is provided with a first perforation and a second perforation; the stopping part of the reversing part is plugged into and penetrated through the second perforation of the braking part; since the size of the connecting rod of the reversing part is smaller than the size of the second perforation of the braking part, and relative displacement occurs between the second perforation and the connecting rod due to the push of a brake-pushing element on the braking part, the connecting rod of the reversing part is limited within the second perforation of the braking part after assembly. The improved ratchet wheel wrench has the advantages that the assembly of the braking part and the reversing part are easier and the assembly efficiency is enhanced.

The specific embodiment
See also Fig. 1 to Fig. 5, be the selected example structure of the present invention shown in the figure.
Present embodiment provides a kind of improved ratchet spanner construction, and it comprises:
One head 1, it is to be extended by a shank 2, and head 1 is provided with one first perforation 11, and this first perforation 11 is communicated with one first groove 12 and one second groove 13 to shank 2 directions in head 1, and second groove 13 is to be positioned at 12 of first perforation, 11 and first grooves, and head 1 be provided with in second groove, 13 positions one perpendicular to shank 2 bearing of trends the chute 14 of horizontally set, and connect this chute 14 and this second groove 13 with an elongated hole 15.
One elastic top push piece 3, it is arranged in first groove 12 of this head 1 and protrudes from second groove 13, and in second groove 13, be provided with one and push up the part 4 of pulling, it is positioned at the end that elastic top push piece 3 protrudes from second groove, 13 parts, this elastic top push piece 3 is compression springs in the present embodiment, and this top part 4 of pulling is metal balls.
One brake 5, it is arranged in second groove 13 of this head 1, and its end that is positioned at first groove 12 then has the portion of being pulled 51 to the oblique setting in both sides, and this brake 5 has a stopper tooth 52 in first perforation, 11 1 ends of head 1, and in this brake 5, be provided with one run through the top end second the perforation 53, it is a triangle perforation in present embodiment, and this brake 5 inwardly is provided with a recess 54 (as shown in Figure 2) with respect to the other end of the chute 14 of head 1 around this second perforation 53.
One reversing piece 6, it has a connecting rod 61, and an end of connecting rod 61 is provided with a shifting block 62, and is provided with a stop part 63 in the other end.These connecting rod 61 sizes are less than the perforation of second in this brake 5 53, and this connecting rod 61 is similarly triangle in the stop part 63 of an end setting and second perforation 53 of this brake 5 in the present embodiment, and size is rough identical.
One ratchet ring gear 7, its outer shroud be one with the ring tooth 71 of stopper tooth 52 engagement of this brake 5, and interior ring is the operate portions 72 of a plum blossom moulding, and this ratchet ring gear 7 is to be placed in first perforation 11 of this head 1, and stopped by an elasticity button 8 and locate.
By said structure as seen, when this ratchet spanner is assembled, earlier this elastic top push piece 3 is arranged in first groove 12 of this head 1, after this top part 4 of pulling is located at the end that this elastic top push piece 3 protrudes from second groove 13, again this brake 5 is inserted in second groove 13 of this head 1, and then this ratchet ring gear 7 is inserted first of this head 1 bore a hole 11, and stop that with this elasticity button 8 this ratchet ring gear 7 of location is in head 1.
After finishing assembly, promptly as seen second of this brake 5 bore a hole 53 by these head 1 its elongated hole 15 direct-views that are arranged in chute 14, after the stop part 63 of this reversing piece 6 is placed in second perforation 53 of this brake 5, again to the second perforation 53 direction application of forces of shifting block 62 to this brake 5, and press down and make this stop part 63 clamp-on and penetrate second perforation 53 and enter in the recess 54 of this brake 5 of this brake 5 by connecting rod 61, this shifting block 62 then fits in the chute 14 of this head 1.Because second perforation, 53 sizes of this brake 5 are than the connecting rod 61 greater than this reversing piece 6, so second 53 of the perforation of the connecting rod 61 of this reversing piece 6 and brake 5 have the gap.And in the connecting rod 61 of reversing piece 6 pack into brake 5 second the perforation 53 after, be subjected to the part 4 pushing tows skew that makes progress of pulling of tops in second groove 13 of head 1 because of brake 5, and the shifting block 61 of this reversing piece 6 is subjected to the chute 14 of head 1 to limit its upper and lower displacement, make its connecting rod 61 and second perforation 53 of this brake 5 present the situation of relative displacement, the stop part 63 that makes this reversing piece 6 is in the recess 54 of this brake 5, because of being barred from second perforation 53 of these brake 5 limiting rods 61 these brakes 5 of disengaging.
