Detailed description of the invention

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from this utility model and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.

As shown in Figures 1 to 6, this utility model provides a kind of ratchet spanner 100 having elastic positioning structure, including drive rod 120, swivel head 200 and a locking button 250.In the present embodiment, ratchet spanner 100 preferably also includes the operation handle 110 that can house drive rod 120, quickly rotation or back and forth pulling of level by erectility operate handle 110, make swivel head 200 turn working substance (figure is slightly) tightly or turn pine.

Drive rod 120 includes a forked arm 130, the forked opening 150 formed in forked arm 130, the axial hole 160 connecting forked opening 150 and the radial hole 170 intersected with axial hole 160.Forked arm 130 as depicted also includes that two prongs (sign), forked opening 150 are formed between two prongs.Swivel head 200 is articulated in forked arm 130 two ends, swivel head 200 includes a spherical housing 210, be located in spherical housing 210 a ratchet mechanism (figure is slightly), it is located at multiple detents 220 of spherical housing 210 and through swivel head 200 and a pivot axis 230 at forked arm 130 two ends, wherein, pivot axis 230 is vertical with radial hole 170.

Swivel head 200 also includes being convexly equipped in the square shape output 240 of spherical housing 210 one end, the place kick 242 being located at output 240 1 sidewall and the ratchet mechanism (figure is slightly) being connected with side's shape output 240.Ratchet mechanism is also arranged in spherical housing 210, and the place kick 242 by output 240 engagingly assembles various various sizes of sleeve (figure is slightly), working substance to turn tight or turns pine.Owing to ratchet mechanism is existing apparatus, do not add at this to repeat.

In the present embodiment, drive rod 120 further includes two supporting bolt 132, bellend 140 and bodies of rod 142.Each supporting bolt 132 is each passed through forked arm 130 two ends and is fixed between spherical housing 210 and forked arm 130, wherein pivot axis 230 is hypothetically through the axle center of each supporting bolt 132, make swivel head 200 can rotate freely through a special angle with pivot axis 230 for axle center at forked opening 150, such as 0 degree to 270 degree.Bellend 140 is arranged between forked arm 130 and the body of rod 142, and the size of bellend 140 is more than the size of the body of rod 142, and axial hole 160 is preferably all opened in bellend 140 with radial hole 170.In other words, locking button 250 is placed in bellend 140 equally, so makes the ratchet spanner 100 of the present embodiment have preferably intensity and operation quality.

Additionally, each detent 220 of the present embodiment at least includes one first detent 222 being arranged at spherical housing 210 top dome and is arranged at one second detent 224 of spherical housing 210 sidewall.90 degree of angles are preferably formed, in order to user operates ratchet spanner 100 at erectility (centrage of output 240 is consistent with the axis of drive rod 120) or level (centrage of output 240 becomes vertical with the axis of drive rod 120) between first detent 222 and the second detent 224.The shape of detent 220 is the most corresponding with the shape of breech lock rod 270, fixes detent 220 in order to breech lock rod 270.

Locking button 250 includes being arranged in an elastic fastener 260 of radial hole 170 and being arranged at a breech lock rod 270 in axial hole 160.Elastic fastener 260 flexibly interlocks breech lock rod 270, and makes breech lock rod 270 lockings or depart from arbitrary detent 220.Please also refer to shown in Fig. 7, elastic fastener 260 has a junction 262 and two ends 264, and two ends 264 are the most one-body molded with connecting portion 262 makes.Connecting portion 262 is through radial hole 170, and two ends 264 then protrude from outside radial hole 170 and contact at drive rod 120 surface.

In order to control the action that breech lock rod 270 can stretch out in axial hole 160 and retract, two ends 264 of elastic fastener 260 necessarily be formed fulcrum, is driven the displacement of breech lock rod 270 by the deflection of connecting portion 262 itself.Elastic fastener 260 at the present embodiment also has two kinks 266 being connected with two ends 264, and two surfaces on drive rod 120 surface, i.e. bellend 140, then it is provided with two short slots 144, two kinks 266 are made to be placed in two short slots 144, to be stably located in two short slots 144.But in various other embodiments, elastic fastener 260 also may utilize two ends 264 and is directly inserted in drive rod 120 surface, reach to be formed the purpose of fulcrum.

Breech lock rod 270 also includes that in radial hole 170 one buckles portion 272, and connecting portion 262 is then provided with the perforation 268 with button portion 272 snapping or a breach (figure is slightly).In the embodiment as shown in Fig. 2, Fig. 4 and Fig. 6, a button portion 272 preferably annular groove, make annular groove engaging perforation 268 or breach.Additionally, in order to avoid breech lock rod 270 distance of axial displacement are too big, cause the oversize of radial hole 170 to affect intensity or the operation quality of drive rod 120.The drive rod 120 (i.e. bellend 140) of the present embodiment further includes the tank 162 connected with radial hole 170, wherein tank 162 setting corresponding with axial hole 160, enables breech lock rod 270 to be placed in tank 162 when retracting.

Please also refer to shown in Fig. 7, the cross section of elastic fastener 260 is preferably flap structure, and the surface of laminated structure driven in parallel bar 120, in order to user pressing elastic fastener 260.An elastic fastener 260 preferably c-type button at this indication.But in various other embodiments, elastic fastener 260 also can be a trapezoid buckle, a polygon button or other fastener being suitable for.Additionally, the excellent end of breech lock rod 270 is the most identical with the shape of each detent 220, such as circular arc or other shape being suitable for, to fix each detent 220.

The detailed method of operation of the ratchet spanner 100 of this utility model further explained below tool elastic positioning structure.As shown in Figures 1 and 2, when the elastic fastener 260 non-stress of locking button 250, breech lock rod 270 stretches out forked opening 150 and fixes the first detent 222 of swivel head 200.Now, locking button 250 is one lockup state/position.As shown in Figures 3 and 4, when elastic fastener 260 stress deformation of locking button 250, connecting portion 262 drives the portion that buckles 272 of breech lock rod 270 to move towards tank direction 162 linkedly, until breech lock rod 270 departs from the restriction of the first detent 222.Now, locking button 250 is one release conditions/position.

When locking button 250 is in release conditions, user can arbitrarily rotate swivel head 200 to angle as shown in Figures 5 and 6.When discharging elastic fastener 260, connecting portion 262 recovers elastic and drives breech lock rod 270 to stretch out, and makes breech lock rod 270 again fasten the second detent 224 of swivel head 200.

Therefore the easiest and simple in construction in this utility model operation.By pressing locking button 250 elastic fastener 260, rotate swivel head 200 to first required detent the 222, second detent 224, then discharge locking button 250 and can be rapidly achieved the purpose of locking swivel head 200.In addition, locking button 250 has the effect automatically keeping lockup state, that is the locking button 250 of the present embodiment is normally off (Normal Close Status) design, is not necessary to operation bidirectional, therefore swivel head 200 will not arbitrarily rotate, and has the convenience of safety and operation.

Embodiment described above is only the preferred embodiment lifted by absolutely proving this utility model, and protection domain of the present utility model is not limited to this.The equivalent that those skilled in the art are made on the basis of this utility model substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
