This stripping unit 40 has an axostylus axostyle 41, several push rods 42, several springs 43 and returning springs 44.This axostylus axostyle 41 is located at this operative end 11 along this axis L1 axle, and has a minor diameter part 411 in the middle of being located at, one along this axis L1 be located at these minor diameter part 411 1 sides and to should second the large-diameter portion 412 of perforation 115, one along this axis L1 be located at these minor diameter part 411 opposite sides and to should first the extension 413 of perforation 113, a blocking pearl 414 of being located at this extension 413, a conical surface portion 415 and a press section 416 that is attached at these large-diameter portion 412 outsides that is engaged on this minor diameter part 411 and these large-diameter portion 412 joining places, these blocking pearl 414 frictions are positioned at these first perforation 113 inner peripheral surfaces and can produce the location with respect to this lever 10, described push rod 42 is located in respectively in the endoporus 314 of described drive rod 31, and respectively has the groove 421 of a described steel ball 313 of correspondence and one to pearl body 422 that should axostylus axostyle 41, described spring 43 is installed in respectively between described push rod 42 and the described drive rod 31, its elastic force perseverance makes described push rod 42 keep the trend that moves towards this axostylus axostyle 41, and make described groove 421 and described steel ball 313 keep dislocation, this returning spring 44 is butted between this press section 416 and this second pin plate 112, and its elastic force perseverance makes this minor diameter part 411 have movement tendency towards described push rod 42.
Fig. 5 and shown in Figure 6 for another example, under normal condition, the axostylus axostyle 41 of this stripping unit 40 is subjected to the elastic force effect of this returning spring 44, can make this press section 416 be away from this second pin plate 112, and make this minor diameter part 411 corresponding to described push rod 42, at this moment, described push rod 42 is subjected to the elastic force effect of described spring 43, move towards this axostylus axostyle 41 in the capital, and described pearl body 422 is held against on this minor diameter part 411, the groove 421 of described push rod 42 keeps dislocation with described steel ball 313, and described steel ball 313 is subjected to pushing away of described push rod 42 and pulls and can protrude outwardly, if be arranged with sleeve (figure does not show) on this drive division 312, then just can make sleeve produce the location with respect to this drive division 312, and for operating nut.
And as shown in Figure 7, when the bidirectional operation nut is desired in selected ratchet unit 30, then rotate this spiral cover 22, and utilize spring steel ball 231 inlay cards of this location division 23 being arranged in middle groove 232, at this moment, the described part 223 of pulling that pushes away does not all contact described sour jujube piece 32, so utilize the elastic force effect of this elastic parts 33, can make described sour jujube piece 32 a position of engagement, and can reach the purpose of this drive rod 31 of two-way interlock when operating this lever 10 with 311 engagements of this ratchet.
Again as shown in Figure 8, when the one-way operation nut is desired in selected ratchet unit 30, then rotate this spiral cover 22, and this spring steel ball 231 is embedded and located in this groove 233 (or this groove 234), at this moment, wherein one pushes away part 223 one of them the sour jujube piece 32 of promotion of pulling, make this sour jujube piece 32 be positioned at a separation point position of separating with this ratchet 311, and another pushes away the part 223 of pulling and does not contact another sour jujube piece 32, can make this sour jujube piece 32 and this ratchet 311 keep engagement, and can reach the purpose of this drive rod 31 of unidirectional interlock when operating this lever 10.When this spiral cover 22 of reverse rotation, then can reach the purpose (figure does not show) of commutation interlock, therefore,, can reach the purpose that three-dimensional is switched by rotating described spiral cover 22.
Fig. 9 and shown in Figure 10 and for example, when desire stripping sleeve, the press section 416 of this axostylus axostyle 41 of operator presses, this axostylus axostyle 41 moves along this axis L1, utilize this conical surface portion 415 to push away the described push rod 42 of pulling, up to this large-diameter portion 412 during corresponding to described push rod 42, described push rod 42 can produce displacement along centre line L 2 with respect to this drive rod 31 simultaneously, and described steel ball 313 is moved into towards described groove 421, the sleeve that feasible script is set in described drive division 312 can come off automatically, and reaches the purpose of quick pulling off sleeves.
Therefore, again effect of the present utility model is summarized as follows:
One, utilize this driving head 20 to rotate with respect to the operative end 11 of this lever 10, and several ratchet unit 30 are installed on this driving head 20, then produce bull formula ratchet spanner, and produce the function of different size operation at single ratchet spanner, not only do not need to purchase the ratchet spanner of different size simultaneously, can not increase the expense of purchasing, and the quantity of instrument can be simplified, the management of instrument is also more or less freely.
Two, utilize described spiral cover 22 to rotate, can produce switch operation, and can reach the purpose that three-dimensional is switched with respect to this main body 21.
Three, utilize the setting of this stripping unit 40, can reach the purpose that changes sleeve fast.
