The specific embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, its specific embodiment of spanner, structure, feature and the effect thereof of the trilateral clamping that foundation the present invention is proposed, describe in detail as after.
Relevant aforementioned and other technology contents, characteristics and effect of the present invention can clearly present in the following detailed description that cooperates with reference to graphic preferred embodiment.
Consult Fig. 2, Fig. 3 and Fig. 4, Fig. 2 is the exploded perspective schematic diagram of spanner one preferred embodiment of the present invention's one trilateral clamping, and Fig. 3 is a schematic perspective view of this preferred embodiment, and Fig. 4 is the cutaway view along Fig. 3 midship section IV-IV direction.The spanner of the trilateral clamping of a preferred embodiment of the present invention comprises a body 3, a braking group 4, a clamping group 5, and a driving group 6.
Above-mentioned body 3 has a head 31 that is formed on an end, a shank 32 that is formed on the other end, and runs through a perforation 33 of this head 31 along an axis X.
Above-mentioned braking group 4 is arranged in the perforation 33 of this body 3, and has a brake component 41, ratchet-gear wheel 42, three cushion blocks 43, and three spigots 44.
This brake component 41 and this ratchet-gear wheel 42 are the upper and lower intersegmental distances of being separated by, and have three perforation 411,421 of upper and lower mutual correspondence respectively, and an edge 412,422.Aforementioned perforation the 411, the 421st is isogonism respectively and distributes, and is extended along the other end of a straight path to contiguous this edge 412,422 by an end of contiguous this axis X.
Above-mentioned clamping group 5 has three jaws 51, and is defined in the folder of one between the aforementioned jaw 51 mouth 52.
This each jaw 51, have the clamping part 511 that passes 42 perforation 421 of this ratchet-gear wheel and pass this body 3 respectively, be set in these body 3 perforations 33 and pass one of these brake component 41 perforation 411 and lead portion 512, and be formed on this clamping part 511 and lead 512 in portion with this and cross over this brake component 41 and bore a hole 411,421 two fins 513 of this ratchet-gear wheel 42.
Above-mentioned driving group 6 has an actuator 61 and one urgent 62.
This actuator 61 is sealing this body 3 perforations 33 and can do the limited angle turn, and has to be recessed to form in a bottom surface and with aforementioned jaw 51 and lead most the linkage part 611 that portion 512 plugs together, and reaches an edge 612.
This urgent 62 is to pass this actuator 61 along this axis X, and has a startup portion 621 that is emerging in outside this actuator 61, and a limiting section 622 that passes this actuator 61 and screw togather with this brake component 41.This startup portion 621 cooperates this limiting section 622 to screw togather urgent this actuator 61 of the degree of depth to be anchored on this body 3 with this brake component 41.
See also Fig. 4, Fig. 5 and shown in Figure 6, Fig. 5 is a vertical view of this preferred embodiment amplification one folder mouth, and Fig. 6 is the upward view that a folder mouth is amplified in this preferred embodiment.The present invention in use, only need this startup portion 621 of urgent 62 of turn, pine oil is also removed this urgent the 62 urgent state with this actuator 61, just can be under this urgent 62 situation that does not break away from this brake component 41, this actuator 61 of turn counterclockwise, make this actuator 61 in the process of turn, change the angle position of this linkage part 611, to make the portion that leads 512 of aforementioned jaw 51 follow the radian of this linkage part 611 be that the center is equidistant with this axis X inwardly shrinks, and behind the extremely pre-sizing of the bore that dwindles this folder mouth 52, screw this urgent 62 again, make this startup portion 621 cooperate these limiting sections 622 to screw togather that urgent this actuator 61 of the degree of depth is anchored on this body 3 with this brake component 41 and can't turn.Whereby, this more small-bore folder mouth 52 can cooperatively interact with the less spiral shell spare 71 of external diameter, and then compels to support the solid all sides at spiral shell spare 71 of ring with the clamping part 511 of aforementioned jaw 51, and can reach the purpose of this spiral shell spare of turn 71.
See also Fig. 4, Fig. 7 and shown in Figure 8, Fig. 7 is the vertical view that a folder mouth is dwindled in this preferred embodiment, and Fig. 8 is the upward view that a folder mouth is dwindled in this preferred embodiment.When this urgent the 62 urgent state of removing with this actuator 61, this actuator 61 of turn equally in a clockwise direction, making the portion that leads 512 of aforementioned jaw 51 follow the radian of this linkage part 611 is that the center equidistantly expands outwardly with this axis X, and the bore that amplifies this folder mouth 52 is locked this urgent 62 fastening this actuator 61 and this brake component 41 again to pre-sizing.Whereby, the folder mouth 52 of this larger caliber can cooperatively interact with the bigger spiral shell spare 72 of external diameter, and then it is solid in spiral shell spare 72 1 all sides to compel to support ring with the clamping part 511 of aforementioned jaw 51, reaches the purpose of this spiral shell spare of turn 72.
What deserves to be mentioned is that the present invention can cooperate the setting of this ratchet-gear wheel 42, make the present invention have the function of unidirectional turn of general ratchet spanner and commutation turn.
According to as can be known above-mentioned, the spanner of trilateral clamping of the present invention has following advantage and effect:
1, direct folder mouth 52 bores between the aforementioned jaw 51 of convergent-divergent of the present invention, to be suitable for the spiral shell spare 71,72 of different size, not only use processing ease, and the program of the quantity that can simplify accessory when replacing accessory, so can promote use go up and carry, the convenience when taking in.
2, in addition, the spanner of trilateral clamping of the present invention, on the function except can replacing general telescopic spanner, jaw 51 of the present invention also goes for having the spiral shell spare (not shown) of inner hexagonal hole, and replace general die nut, make applicability of the present invention comparatively extensive, and can promote the practicality in the use.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
