Detailed Description

The present invention will be further explained with reference to the drawings and examples. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and therefore show only important constituent parts related to the present invention.

As shown in fig. 1 to 14, the utility model relates to a wrench includes fixed jaw 1 and with fixed jaw 1 fixed connection handle 3 as an organic whole, the inside of handle 3 is provided with flexible groove 4, for the installation and prevent that inside part from skidding and turning to, flexible groove 4's structure is middle big little structure in two (or other anomalous shape all can), inside hole can be circular also can be square, circular in this embodiment, big circular upper and lower both ends respectively set up two bellied recesses in the middle, make internally mounted's part more steady, can not fall out the handle outside and combine inseparabler. In addition, an opening and closing groove 5 which penetrates through the inner telescopic groove 4 in the longitudinal direction is arranged above (or below) the handle 3, an elongated sliding groove 6 which penetrates through the opening and closing groove 5 is arranged by taking the longitudinal center of the opening and closing groove 5 as a reference, and the sliding groove 6 becomes the moving track of internal parts.

Still include a activity 2 and with activity 2 fixed connection's of keeping silent telescopic link 7, in order to increase telescopic link 7 stability, make it can not skid and turn to, telescopic link 7 structure is just can insert in flexible groove 4 and identical with the telescopic link. The upper side of the telescopic rod 7 is provided with a first fixed tooth 8 so that the whole side surface looks like a rack, and the side of the first fixed tooth 8 is positioned above and corresponds to the opening and closing groove 5.

A switch plug 9 is arranged inside the switch slot 5, the shape and the size of the switch plug 9 are matched with those of the switch slot 5, and a shaft hole 10 is arranged at the position corresponding to the sliding slot 6; after the switch plug 9 is arranged in the switch groove, the connecting shaft 11 is in threaded connection with the shaft hole 10, so that the switch plug 9 is fixed in the switch groove 5, and the sliding distance of the switch plug 9 depends on the length of the sliding groove 5; in order to make the friction of the connecting shaft 11 a little higher, the diameter of the connecting shaft 11 is identical with the width of the chute 6, and the connecting shaft is just arranged in the chute 6 but is not too loose; in order to adjust the switch plug 9 through the connecting shaft 11, a push-pull member 12 is fixedly connected to the outer end of the connecting shaft 11.

A second fixed tooth 13 integrally connected is arranged below the switch plug 9, and the second fixed tooth 13 and the first fixed tooth are in a meshed state; the mutual engaging surface of the first fixed teeth 8 and the second fixed teeth 13 is less than or equal to 90 degrees, so that the engagement between the two fixed teeth can be clamped without slipping.

The using method comprises the following steps: the switch plug 9 is mounted in the switch slot 5 of the handle 3 by means of a connecting shaft 11, while the connecting shaft 11 is a control member of the switch plug 9. The movable jaw 2 and a telescopic rod 7 fixedly connected with the movable jaw 2 into a whole are arranged in the fixed jaw 1 and a telescopic groove 4 in a handle 3 fixedly connected with the fixed jaw 1, and the movable jaw 2 and the fixed jaw 1 are in a state of being opposite in pairs; when the adjustable jaw opening device is used, the push-pull component 12 is pushed and pulled upwards, so that the switch plug 9 is driven to move upwards, namely the second fixed teeth 13 below the switch plug 9 are pushed to move upwards, and the second fixed teeth 13 integrally connected below the switch plug 9 are separated from the first fixed teeth 8, so that the telescopic rod 7 can directly pull the telescopic rod 7 to adjust the width of a jaw opening according to the size of a nut to be adjusted, and can directly and rapidly stretch and retract one step to one position; after the movable jaw 2 reaches the preset position, the push-pull component 12 is pushed and pulled downwards, so that the second fixed teeth 13 below the switch plug 9 and the first fixed teeth 8 are in a meshing state again, and the movable jaw 2 is fixed. When the width of the jaw needs to be adjusted again, the push-pull component 12 only needs to be pushed and pulled upwards again, so that the second fixed teeth 13 below the switch plug 9 are disengaged from the first fixed teeth 8, the telescopic rod 7 can adjust the width of the jaw randomly again, and after the preset width is reached, the push-pull component 12 is pushed and pulled downwards again, so that the second fixed teeth 13 are re-engaged with the second fixed teeth 8, and the purpose of fixing the jaw is achieved.

The embodiments of the present invention have been described with reference to the accompanying drawings, but these descriptions should not be construed as limiting the scope of the present invention, which is defined by the appended claims, and any modification based on the claims is the scope of the present invention.
