Description

The multifunction active wrench

Technical field

The utility model relates to a kind of monkey wrench.

Background technology

At present, the structure of monkey wrench is a movable bolt die, another bolt die with pull body, handle is integrated, weak point is because of having only a movable bolt die, movable bolt die must be consistent with another bolt die shape, so the bolt die fixed in shape, working face is narrow and folding speed is very slow; Cause is pulled body, handle is integrated, and the anglec of rotation is limited when the turn of the screw; Limited because of decreased food again, run into stubborn motionless screw and will add sleeve.

Summary of the invention

The purpose of this utility model is to provide that a kind of working range is big, bolt die folding speed fast, handle has very big operating angle, the adjustable multifunction active wrench of decreased food.

To achieve these goals, the technical solution of the utility model is: the multifunction active wrench, it comprises movable bolt die, wrench body, handle, turn threaded rod, turn threaded rod 3 is positioned at the turn threaded rod chamber 8 of wrench body 4, movable bolt die 1 is meshed with the turn threaded rod, and wrench body 4 is provided with turn chamber 2, and turn chamber 2 communicates with turn threaded rod chamber 8, it is characterized in that movable bolt die 1 is 2, turn threaded rod 3 left and right sides hand of spirals are opposite; Wrench body 4 is flexibly connected by latch 5 with an end of handle 6, and elastic positioning device and locking device are positioned at handle rotating drum 10, and wrench body 4 is fixed by elastic positioning device and locking device with handle 6 during work; Connect an inner handle 7 by positioner in the other end of handle 6.

Bolt die of existing monkey wrench is fixed, the shape of another movable bolt die will be correspondingly, so bolt die fixed in shape, and the utility model adopts 2 movable bolt dies, 2 movable bolt dies all can unload simultaneously, load onto, thereby can change the movable bolt die of different shape as required, as change elongated movable bolt die, promptly working range is big; Owing to adopt 2 movable bolt dies, bolt die folding speed is fast again; Wrench body 4 is flexibly connected by latch 5 with an end of handle 6, and handle 6 and wrench body 4 can be regulated between-60-+60 degree, are locked by locking device then, and handle 6 has very big operating angle; Connect an inner handle 7 by positioner in the other end of handle 6, inner handle 7 can freely stretch in handle 6, and decreased food can be adjusted.

The wherein movable bolt die of 1-, 2-turn chamber, 3-turn threaded rod, 4-wrench body, 5-latch, 6-handle, 7-inner handle, 8-turn threaded rod chamber, 9-control button, 10-handle rotating drum, 11-locating hole, 12-pin hole, the right wedge card base of 13-, 14-locking ball, 15-left side wedge card base, 16-control button hole, 17-elasticity locking ball, 18-half positive 12 limit shape faces, 19-elasticity locking ball hole, 20-wedge card base hole.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the multifunction active wrench, it comprises movable bolt die, wrench body, handle, turn threaded rod, turn threaded rod 3 is positioned at the turn threaded rod chamber 8 of wrench body 4, movable bolt die 1 is meshed with the turn threaded rod, and wrench body 4 is provided with turn chamber 2, and turn chamber 2 communicates with turn threaded rod chamber 8, movable bolt die 1 is 2, and turn threaded rod 3 left and right sides hand of spirals are opposite; Wrench body 4 is flexibly connected by latch 5 with an end of handle 6, and elastic positioning device and locking device are positioned at handle rotating drum 10, and wrench body 4 is fixed by elastic positioning device and locking device with handle 6 during work; Connect an inner handle 7 by positioner in the other end of handle 6.

Described elastic positioning device is made up of the elasticity locking ball 17 in the handle rotating drum 10 of wrench body 4, the elasticity locking ball hole 19 on the handle 6, and elasticity locking ball 17 matches with elasticity locking ball hole 19.

Described locking device mainly is made up of control button 9, right wedge card base 13, left wedge card base 15, stage clip, right wedge card base 13, left wedge card base 15 are positioned at handle rotating drum 10, and the outer lateral mass of right wedge card base 13, left wedge card base 15 lays respectively in the wedge card base hole, wrench body 4 both sides 20; Be provided with stage clip between right wedge card base 13 and the left wedge card base 15, the control button hole 16 that control button 9 passes on the wrench body 4 contacts with stage clip; During locking device locking, right wedge card base 13, left wedge card base 15 contact with handle 6 ends half positive 12 limit shape faces 18 respectively.When rotating, press control button 9, two wedge card bases and under the effect of stage clip power, separate, handle just can rotate like this, fixedly the time, only needs the wedge card base is pushed away toward middle one after the rotation, control button just two is carved capable card base and is blocked from being about to, and handle has also just been fixed like this.
