Description

Multi-purpose moving spanner

The utility model relates to a kind of Multiple adjustable wrench, belongs to hand tools.

Chinese patent ZL93205903.1 discloses a kind of Multiple adjustable wrench, and its structure has guaranteed that nut can enter the spanner mouth in arbitrary position, and just can turn continuously once interlock, has improved operating efficiency.But also there are the following problems: at first, when pulling nut, because movable lug is arranged on the moving tongue, so turning of movable lug is subjected to force direction to be in the anti-state of pulling, do not meet country to the desired operational procedure of adjustable wrench.Secondly, movable lug can not be fixed and use as original adjustable wrench.

Task of the present utility model is to provide a kind of when turning nut, and the turning of movable lug is in by force direction just to pull state and can as required movable lug be fixed and the Multiple adjustable wrench that uses as common adjustable wrench.

Task of the present utility model is finished like this, a kind of Multiple adjustable wrench, it comprises handle 1, be positioned at the wrench body 12 with a dead tongue 3 of handle 1 one ends, be separately positioned on threaded 13 of its bottom on the wrench body 12 moving tongue 9, with making of matching of screw thread bar 13 trapezoidal thread bar 2 that tongue 9 moves and the movable lug 6 that on tongue 3 extremely, is connected.

Below in conjunction with accompanying drawing the utility model is further described below.

Fig. 1 is the utility model topology view.

Fig. 2 is the partial enlarged drawing of the B of the utility model Fig. 1.

Fig. 3 is that the C of the utility model Fig. 1 is to partial enlarged drawing.

Movable lug 6 of the present utility model is active the connection with dead tongue 3, on dead tongue 3 and movable lug 6, open the revolution axis hole respectively earlier, by gyroaxis 4 insertion revolution axis holes are reached movable lug 6 is connected with dead the active of tongue 3 then, make the movable lug 6 can be as required and wraparound rotating shaft 4 movable certain angles, to reach the size of control jaw 7.

Movable lug 6 of the present utility model is provided with locating hole 15, an end of fixed locating stud 14 in it, the active connection locating piece 5 of the other end of alignment pin 14, and can make locating piece 5 is about fulcrum movable 90 ° with alignment pin 14, in the time will doing the monkey wrench use, then locating piece 5 is in locating piece 5A position, the off working state position that promptly mediates, make locating piece 5 on correct the locating piece groove 11 that is positioned on the dead tongue 3, at this moment movable lug 6 can be the fulcrum certain distance that leans forward or swing back with gyroaxis 4 according to the size of nut 8 just, adapts to nut 8 changes to the D limit from the S limit size with the size of regulating jaw 7; In the time will doing common adjustable wrench use, only with hand is stirred 90 ° to the left or to the right with locating piece 5 so, make locating piece 5 on correct in the groove of formation between dead tongue 3 and movable lug 6, fixing movable lug 6 thus, unlikely movable lug 6 is that fulcrum leans forward or swings back with gyroaxis 4, thereby realizes that the utility model is made common adjustable wrench to be used.

When using the utility model, pull the trapezoidal thread bar 2 that is located on the screw shaft 10, move, make tongue 9 cooperations be with the dead tongue 3 interlock nuts 8 of movable lugs 6 thereby make in the groove of tongue 9 on wrench body 12 by screw thread bar 13 with hand.Because when movable lug 6 opened, the dead tongue 3 of band movable lug 6 was the little taper state of outer imperial palace with moving tongue 9 formed jaw 7A, promptly the size of jaw 7A is greater than nut 8.Thereby when work, be convenient to interlock nut 8 and unclamp spanner; In addition, the swing of angle because movable lug 6 can lean forward or swing back, thus play guide effect.So, as long as handle 1 is done a little low-angle swing, just can make the S limit interlock of dead tongue 3 with the nut 8 of band movable lug 6, can hit to movable lug 6 bottoms.Because the effect of lever, it is in place and nut 8 stung tightly enter duty that movable lug 6A moves to movable lug 6 positions, when pulling handle 1 certain angle, nut 8 is just corresponding to rotate to an angle, and when spanner withdraw from very a little bit smaller apart from the time, because nut 8 still is in the nut 8A position in the jaw 7A position, can do to pull pinch bar 1 certain angle in the other direction so need not make spanner all withdraw from nut 8, at this moment nut 8 is touched the inner edge of movable lug 6 and is become the inner edge that the D edge joint touches movable lug 6A gradually by former S edge joint.Thereby promote movable lug 6 opened with certain angle to movable lug 6A position, repeating above-mentioned steps then just can screw nut 8 fast or unscrew, when pulling handle 1, a kind of thrust is arranged at 8 pairs of movable lug 6 bottoms of nut, the S limit that makes snake 6 alive sting tight nut 8 more firmly, thereby can in the process of turning, not occur skidding.

The technical program also can be used on the fork spanner, then makes fork spanner can realize that any direction freely inserts jaw of spanner with nut, and or else just can pull continuously with withdrawing from jaw fully once the interlock nut.

The utility model is owing to be connected movable lug 6 on the dead tongue 3, so when turning nut 8, the direction that turns of movable lug 6 is in the state of just twisting, met country to the desired operational procedure of adjustable wrench, and can be have as required pulled locating piece 5 certain angles and can realize that just the function between Multiple adjustable wrench and the common adjustable wrench changes with hand.
