Shown in Fig. 5 and Fig. 6, it is the action diagram of ratchet spanner first embodiment that the present invention easily assembles.This ratchet spanner 10 in use, after being first socketed working substance with the drive division 31 of this ratchet 30, grip the shank 22 of this body 20 and forward rotate namely can switching working substance (as shown in Figure 5), when operating this ratchet spanner 10 backwards rotation, this this ratchet block 42 of ratchet 30 pushing tow, along the past direction slippage (as shown in Figure 6) near this fixture block 41 of abutment walls 242 of this body 20, makes this ratchet 30 can rotate relative to this body 20.
Namely this ratchet spanner 10, when assembling, after only needing this clamping and drawing device 40 to be located at the room 24 of this body 20, then completes in the accommodation space 23 this ratchet 30 being installed in this body 20.Because this abutment walls 242 is in concave arc shape, make this fixture block 41 and this ratchet block 42 can because by this elastic component 43 pushing tow away from each other when nature, and then make that this fixture block 41 is resisted against this ratchet 30 and this ratchet block 42 is engaged in this ratchet 30.And because clip is located in this circular rabbet 33 in this accommodation space 23 because of this clip flange 424 when this ratchet 30 assembles, the structure of this ratchet spanner 10 of effective simplification, omit unnecessary work flow, this ratchet spanner 10 is had and produces easily and assemble advantage fast, also reduce the manufacturing cost of this ratchet spanner 10 simultaneously.
With reference to shown in Fig. 7 to Fig. 9, the three-dimensional exploded view of ratchet spanner second embodiment of easily assembling for the present invention and sectional structure chart.The difference of second embodiment of the invention and first embodiment is mainly that this fixture block 41a is also convexly equipped with a clip flange 415a, the clip flange 415a of this fixture block 41a is positioned at this fixture block 41a near the side of this ratchet 30, the clip flange 415a of this fixture block 41a is positioned at face of the dodging 412a of this fixture block 41a, the clip flange 415a clip of this fixture block 41a is in the circular rabbet 33 of this ratchet 30, this fixture block 41a is respectively equipped with a second clamping face 416a in the both sides of clip flange 415a, two second clamping face 416a of described fixture block 41a are resisted against two the first clamping faces 331 of described ratchet 30 respectively, all the other structures of second embodiment are identical with first embodiment, then do not repeat at this.
When this fixture block 41a is provided with this clip flange 415a, this ratchet spanner 10 can be made to have the effect of identical simplification structure, omit unnecessary work flow, this ratchet spanner 10 is had and produces easily and assemble advantage fast, reduce the manufacturing cost of this ratchet spanner 10.
With reference to shown in Figure 10 and Figure 11, the three-dimensional exploded view of ratchet spanner the 3rd embodiment of easily assembling for the present invention and sectional structure chart.The difference of third embodiment of the invention and first embodiment is mainly that the circular tooth part 32b of this ratchet 30b is arranged in circular rabbet 33b, the both sides of this circular rabbet 33b are made to form a block flange 332b respectively, two first clamping face 331b of described ratchet 30b are located on two described block flange 332b respectively, and the circular tooth part 32b of this ratchet 30b is between described two the first clamping face 331b.This ratchet block 42b is respectively equipped with a second clamping face 425b in the both sides of teeth portion 421b, two second clamping face 425b of described ratchet block 42b are resisted against two first clamping face 331b of described ratchet 30b respectively, two sides 411 of described fixture block 41 are also resisted against two first clamping face 331b of described ratchet 30b respectively, all the other structures of 3rd embodiment are identical with first embodiment, then do not repeat at this.
Two the second clamping face 425b by means of described ratchet block 42b are positioned at the design of this ratchet block 42b teeth portion 421b both sides, can simplify the structure of this ratchet block 42b, make this ratchet block 42b production easy and quick.Simultaneously because two sides 411 of described fixture block 41 are also resisted against two first clamping face 331b of described ratchet 30b respectively, make this fixture block 41 also can reach the clip effect of two second clamping face 425b of equivalent described ratchet block 42b, improve the structural strength of this ratchet spanner 10.
With reference to shown in Figure 12 to Figure 14, the three-dimensional exploded view of ratchet spanner the 4th embodiment of easily assembling for the present invention and sectional structure chart.The difference of four embodiment of the invention and the 3rd embodiment is mainly that this body 20c goes back ring-type and is convexly equipped with a block edge 25c in accommodation space 23c, this block edge 25c is positioned at the side of this room 24c, and between one of this block edge 25c, there is class's drop in this block edge 25c and described room 24c two sidewall 241c, forming perforation 251c, this perforation 251c and this accommodation space 23c in this block edge 25c is connected with each other logical.
One of them block of two block flange 332c of described ratchet 30c is in the block edge 25c of this body 20c, and this ratchet 30c is also convexly equipped with a protuberance 34c, and this protuberance 34c is through the perforation 251c of this body 20c.The outer rim of this protuberance 34c forms a first length L1 to the distance of this block between the outer rim of the block flange 332c of this body 20c block edge 25c, this block in the outer rim of the block flange 332c of this body 20c block edge 25c to this ratchet 30c circular tooth part 32c tooth top between distance form a second length L2, this first length L1 is less than this second length L2.
Because this ratchet 30c possesses the ratio that this first length L1 is less than this second length L2, the side making this ratchet 30c cannot have this block edge 25c by this body 20c is deviate from, and guarantees the structural strength of this block flange 332c simultaneously, not easily bursts apart.
