Detailed Description

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.

As shown in fig. 1-5, the novel universal wrench provided by the embodiment of the present invention includes a head 1, a fixed jaw 2, a movable jaw 3 and a handle 4, wherein sliding grooves 5 are respectively provided on two side surfaces of the head 1, sliding blocks 6 engaged with the sliding grooves 5 are respectively provided on two inner side surfaces of the movable jaw 3, the movable jaw 3 can slide on the head 1 by engaging the sliding blocks 6 with the sliding grooves 5, one end of the movable jaw 3 connected with the head 1 is slotted, two sides of the slot are side walls 31, the inner sides of the side walls 31 on two sides are respectively provided with the sliding blocks 6, the sliding blocks are engaged with the sliding grooves 5, so that the movable jaw 3 can slide relative to the fixed jaw 2 to change the distance between the two, the head 1 is provided with a long hole 7 parallel to the sliding grooves 5, the long hole 7 is rotatably connected with a rotating handle 8, one end of the rotating handle 8 is provided with a rotating shaft 9, and the rotating shaft (9) is, the rotating shaft 9 transversely penetrates through the long hole 7, the rotating shaft 9 can slide along the length direction of the long hole 7, the corresponding positions of the rotating handle 8 and the movable jaw 3 are respectively provided with a poking block 10 and a poking groove 11 which are matched with each other, the rotating handle 8 rotates, and the movable jaw 3 is driven to move through the transmission of the poking block 10 and the poking groove 11, so that screws are clamped and loosened.

Preferably, a rack 12 is arranged in the strip hole 7, toggle teeth 13 matched with the rack 12 are arranged on the rear side of the rotating handle 8, when the fixed jaw 2 and the movable jaw 3 clamp the screw, the rack 12 is meshed with the toggle teeth 13 to compress the rotating handle 8, the screw is very firmly clamped, the stability is high, and the phenomenon that the wrench is separated from the screw cannot occur.

And one end of the outer sides of the handle 4 and the rotating handle 8 is provided with an anti-skid part, and the anti-skid part is an anti-skid rubber sleeve 14.

The principle or method of operation of the invention: as shown in fig. 4, when the distance between the fixed jaw 2 and the movable jaw 3 needs to be adjusted, the rotating handle 8 is slightly rotated counterclockwise to separate the rack 12 from the toggle teeth 13, and at this time, the distance between the fixed jaw 2 and the movable jaw 3 can be adjusted at will, as shown in fig. 5, the distance between the fixed jaw 2 and the movable jaw 3 is adjusted to clamp the screw, the rotating handle 8 is gripped clockwise, the rack 12 is engaged with the toggle teeth 13, the toggle block 10 toggles the toggle groove 11 to drive the movable jaw 3 to move towards one side of the fixed jaw 2, so as to clamp the screw.

The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
