Abstract
A switch type ratchet wrench includes a wrench main body, a group of ratchet units and a group of direction control units. The ratchet unit has a drive head and a clamp block. The direction control unit has a shifting button, a lifting element and a positioning pin. The shifting button uses the lifting element to control the clamp block to switch the left and right positions. The positioning pin is perpendicularly inserted into the inner wall of the wrench main body and is embedded with the periphery of the shifting button to position. An overstepping obstruction effect is produced when the shifting button drives the lifting element to pass through the positioning pin. Therefore, the switch type ratchet wrench is convenient to utilize.

The specific embodiment
Aforementioned and other technology contents, characteristics and effect about the utility model, below cooperate the explanation of several preferred embodiments with reference to the accompanying drawings, can clearly present, the utility model suitching type ratchet spanner will be elaborated below by most preferred embodiment and accompanying drawing.
Referring to Fig. 3, Fig. 4 and shown in Figure 5, the utility model suitching type ratchet spanner is in first preferred embodiment, mainly comprise a wrench body 20, a ratchet unit 30 and a direction control module 40, then, after again the detailed construction of above-mentioned each unit and interblock space kenel being specified in.
This wrench body 20 has a head end 21, these head end 21 inside are concaved with one and are first room 211 of justifying the seat hole shape, be concaved with one second room 212 adjacent to first room, 211 1 side edge, be provided with the 3rd room 213 that is the cylindrical hole shape adjacent to second room, 212 1 side edge, be positioned at the 3rd room 213 inwalls in the middle of the place more be provided with a pin-and-hole 214.
This ratchet unit 30 has a driving head 31 that is located in first room 211, one is located in the control lever 32 of driving head 31 centre, one is set in the spring 33 on the control lever 32, one is set in the clip steel ball 34 of driving head 31 inside, and one be arranged in second room 212 with driving head 31 mutually by neighbour's clipping block 35, these driving head 31 peripheries are provided with a ring tooth 311, its place, end is provided with a square bolt part 312, control lever 32 is subjected to the influence that spring 33 elastic force promote, can drive the outer surface that clip steel ball 34 protrudes in square bolt part 312, this clipping block 35 is the blocks that slightly are the first quarter moon shape, its place, front side is provided with a ratchet part 351, the rear side place is provided with one and supports only recess 352, clipping block 35 can be in second room 212 about the activity displacement, make ratchet part 351 be meshed with this ring tooth 311.
More than be the general introduction of each structure of the utility model suitching type ratchet spanner and shape, then, effect statement as the back that action of the present utility model and expection are reached again:
Again referring to shown in Figure 5, under general state, toggle 41 makes interlock by pull part 42 of top with clipping block 32, because alignment pin 43 protrudes from the internal perisporium of the 3rd room 213, when if toggle 41 is wanted the switching right and left position, part 42 steel balls 423 move along the 3rd room 213 inwalls owing to pull in the top, can touch alignment pin 43 and intercepted, make not conversion direction easily of toggle 41, only when the operator confirms 41 groups of commentaries on classics of toggle to be switched to other direction, a little firmly dial and change this toggle 41, make steel ball 423 compression springs 421 and surmounted alignment pin 43, just can allow toggle 41 reach the effect of switching direction position, as shown in Figure 6.
In sum, the utility model suitching type ratchet spanner mainly is in order to improve the defective of general ratchet spanner 10, its employed technological means is that the place inserts the fixed alignment pin 43 of build-in in the middle of wrench body 20 the 3rd room 213 inwalls, this alignment pin 43 protrudes in the internal perisporium face of the 3rd room 213, when switching about toggle 41 is carried out, 43 pairs of toggles 41 of alignment pin can produce spacing obstruct effectiveness, make toggle 41 can't change direction arbitrarily, only when the operator confirms to want switching direction, the obstruction that just can surmount alignment pin 43 a little to toggle 41 application of forces, make commutation action of the present utility model quite certain, have good ease of use, in addition, 43 pairs of toggles 41 of this alignment pin make chimeric, can apace toggle 41 location be installed in the 3rd room 213, have assembling effect quite easily.
What deserves to be mentioned is, the utility model pushes up the variation kenel that the part of pulling also has other different embodiment, referring to shown in Figure 7, the utility model is in second preferred embodiment, other direction control module 50 has a toggle 51, and pushes up pull a part 52 and an alignment pin 53, different with first embodiment is, this top part 52 of pulling is made up of a spring 521 and a hollow pins 522, these spring 521 rear end are provided with a kink 5211, this kink 5211 can move along supporting the 3rd room 213 inwalls, can produce the spacing effect in bullet top to alignment pin 53.
Referring to shown in Figure 8, the utility model is in the 3rd preferred embodiment, other direction control module 60 has a toggle 61, and pushes up pull a part 62 and an alignment pin 63, different with first embodiment is, this top second hollow pins 623 that first hollow pins 622 and that part 62 is set in spring 621 front end places by a spring 621, is set in spring 621 rear end of pulling is formed, second hollow pins 623 can move along supporting the 3rd room 213 inwalls, can produce the spacing effect in bullet top to alignment pin 63 equally.
