The fixed jaw and the movable jaw are flat iron-shaped structures, and the outer edges of the opposite sides of the fixed jaw and the movable jaw are provided with wave-shaped structures.
Wherein, the inner sides of the wave-shaped structures of the fixed jaw and the movable jaw are provided with blade-shaped structures.
The center of the fixed wrench opening is provided with a third through hole with internal threads, the end part of the corresponding connecting rod is provided with external threads matched with the connecting rod, and the fixed wrench opening is screwed with the connecting rod through the threads.
The fixed wrench opening is connected with the connecting rod in a screwing mode, and the end portion of the connecting rod penetrates through the fixed wrench opening and then is limited by a limiting block with internal threads.
The end part of the connecting rod far away from the fixed wrench opening is provided with an external thread, the fixed block is provided with a counter bore for accommodating the end part, the counter bore is provided with an external thread matched with the end part of the connecting rod, and the connecting rod is screwed with the fixed block through the thread.
Wherein, the movable spanner opening and the screw rod are of an integrated structure.
The utility model discloses a concrete operating procedure does: fixing the connecting rod and the fixing block, enabling the movable pull opening and the screw rod to penetrate through the connecting rod and keeping the screw rod to penetrate through the first through hole, enabling the end portion of the screw rod to be connected with the hand wheel in a screwing mode when the screw rod penetrates through the first through hole, fixing the fixed pull opening and the connecting rod, adjusting the fixed pull opening to correspond to the movable pull opening, and then fixing the end portion of the pull opening through the limiting block. When the wrench is used specifically, the displacement of the movable wrench opening is controlled through the rotation of the hand wheel, and the distance between the fixed wrench opening and the movable wrench opening is controlled, so that the object is clamped and fixed or cut off.
Has the advantages that: the utility model discloses compare with the conventional tool and have following advantage:
(1) the utility model has simple structure, each part is combined by itself, the maintenance and the disassembly are convenient, and the utility model can be used for a long time;
(2) the utility model has the advantages that the upper limit of the force application is improved by times compared with the traditional wrench, and the rotating force is converted into pressure through the lever principle;
(3) the utility model is convenient to operate, and the operator can complete the operation without too large acting force;
(4) the utility model discloses a turn the design of mouth and both can accomplish the centre gripping work and also can accomplish and cut off the purpose.
