This retainer component 40 is general is to installing the column structure that hole 143 is shaped by lever 10, and one end of this retainer component 40 is the supporting end 41 of plane kenel, the other end is the thrust end 42 with plural latch 421, and this retainer component 40 by this supporting end 41 vertically X depression the sliding relying part 411 of one scalariform is set, this retainer component 40 receives into the device hole 143 of this lever 10, and the sliding relying part 411 of this retainer component 40 abuts against in the first grooving side 331 of the grooving 33 of this shifting block 30;
One tool heads 50, a pivot part 51 that comprises one end connects an operate portions 52 of the other end, and this pivot part 51 for column structure and periphery form plural tooth portion 511, in this operate portions 52, offer a handle hole 521, on this pivot part 51, run through again a pivot hole 512 is set, this tool heads 50 is placed in these two groups of this lever 10 with this pivot part 51 and establishes portion 12, between 13, and the pivot hole 512 that makes this tool heads 50 is communicated with these two groups of this levers 10 and establishes hole 121, 131, the tooth portion 511 of the pivot part 51 of this tool heads 50 engages towards this lever 10 and with the latch 421 of this retainer component 40, and
One pivot assembly 60, one end has external screw thread 61, other end setting operation portion 62, the operating portion 62 of the present embodiment is inner hexagonal hole, this pivot assembly 60 sequentially runs through this first group of this lever 10 to be established the pivot hole 512 of pivot part 51 of hole 121, this tool heads 50 and this second group and establishes hole 131, and the external screw thread 61 that makes these pivot assembly 60 one end coordinates screw lock to establish hole 131 in this second group, and the other end coordinates and is placed in this first group and establishes in hole 121.
It is more than the structural relation of elasticity clip formula swing-head spanner of the present invention, in the time will using this spanner, this spanner is in the time of normality, the tooth portion 511 of the pivot part 51 of this tool heads 50 is meshed with this retainer component 40, and the supporting end 41 of this retainer component 40 abuts against the fastening part 334 that supports face 333 in the gradual change of this shifting block 30, as Fig. 3, shown in 4, and in the time that user will change the angle of this tool heads 50, pull the clicking section 31 of this shifting block 30, and make these shifting block 30 pivotables and drive to plant to be positioned the reset unit 20 switching sections 23 in linked slot 321, the switching section 23 of this reset unit 20 just can drive this torsion to hold power section 22 and reverse the power of holding,
Simultaneously, in the time of this shifting block 30 pivotable, originally abut against in the gradual change of this retainer component 40 and just can change the position of this retainer component 40 relatively to face 333, and be by the supporting end 41 changing over gradually with fastening part 334 with these portion's 335 relative these retainer components 40 of giving up the throne, as Fig. 5, shown in 6, and because this portion 335 of giving up the throne is longer apart from the periphery distance of this regulation and control portion 32, represent that this retainer component 40 just can more go deep in the grooving 33 of this shifting block 30, and when the grooving 33 of this shifting block 30 is more goed deep into when interior in the position of this retainer component 40, the latch 421 of the thrust end 42 of this retainer component 40 also can depart from and the engaging of the tooth portion 511 of this tool heads 50 pivot parts 51 gradually, and just this tool heads 50 of the free switching of energy of user, adjust the angle of these tool heads 50 relative these levers 10, to be applicable to various workplaces.
And after user adjusts the angle of this working head 50, loosen the strength of these shifting block 30 clicking sections 31 of switch, the reset unit 20 that is plugged in this shifting block 30 also loses the strength of torsion, this reset unit 20 discharges it and is subject to the strength that switching accumulates and resets, when this reset unit 20 resets, this reset unit 20 just can drive this shifting block 30 to get back to initial position, namely make this shifting block 30 return back to the supporting end 41 that supports fastening part 334 relative these retainer components 40 of face 333 with this gradual change, also make this retainer component 40 return back to the tooth portion 511 of this tool heads 50 pivot parts 51 and engage the state of engagement simultaneously.
As shown in the above description, holding power section 22 by the present invention with the torsion of these reset unit 20 helical structures coordinates the arc gradual change of this shifting block 30 to support face 333, make these shifting block 30 normalities push against this retainer component 40 engagements, when operation, only want this shifting block 30 of switch to make this reset unit 20 reverse the power of holding simultaneously and just can carry out the adjustment action of tool heads 50, this shifting block 30 of relieving after operation completes, this shifting block 30 also just can promptly be replied initial position and be formed blocking, very simple in operation, and the structure of elasticity clip formula swing-head spanner of the present invention is very simple, low cost of manufacture, can create higher economic benefit.
In addition, again please refer to Fig. 7, it is to increase locating unit 70 to be set with location shifting block 30 and lever 10, and be, in the regulation and control portion 32 of this location shifting block 30, locating unit storage tank 323 is set, the device groove 141 of this lever 10 arranges a locating slot 144, and this positioning unit 70 comprises a spring 71 and a positioning bead 72, this spring 71 and this positioning bead 72 are placed in the positioning unit storage tank 323 of this location shifting block 30, in the time of normality, this positioning bead 72 is abut against in the device groove 141 of this lever 10 and compress this spring 71, and when adjusting these tool heads 50 angles when 30 1 angles of this shifting block of switching, when this shifting block 30 is switched to this positioning unit storage tank 323 to should locating slot 144 time, this positioning bead 72 loses the strength that device groove 141 abuts against, this spring 71 also loses the strength of compression simultaneously, this positioning bead 72 just can be deviate from and part is held into this locating slot 144 by this positioning unit storage tank 323, finally between this positioning unit storage tank 323 and this locating slot 144, and the position that makes this shifting block 30 is subject to placing restrictions on location, so, under the state that user just can locate at this shifting block 30, adjust this tool heads 50 angles, more promote again the convenience using.
In addition, more implement aspect please refer to the another kind that shown in Fig. 8 is these location shifting block 30 these reset units 20 of location, it is to offer a V-shaped groove 324 in regulation and control portion 32 outer peripheral edges of this location shifting block 30, and the switching section 23 of this reset unit 20 just can be placed in this V-shaped groove 324, in the time of the shifting block 30 of this location of switching, just can these reset unit 20 torsions of while switching hold power by this V-shaped groove 324, and similarly can reach above-mentioned identical effect.
