Detailed Description

The utility model is shown in figures 1-4 and comprises a fixed wrench body 1, a movable wrench body 2 and a square tenon sleeve 3;

The fixed spanner body 1 is horizontally connected with the movable spanner body 2 in a sliding way through a sliding rail mechanism 4; the movable plate body moves on the fixed spanner body in the horizontal direction through the slide rail mechanism 4;

The front end of the fixed spanner body 1 is provided with a fixed spanner lip 11, and the tail end of the fixed spanner body is provided with a mounting hole matched with the square tenon sleeve 3;

the square tenon sleeve 3 comprises a connecting end 31 and a gear 32; the gear 32 and the connecting end 31 are coaxially and fixedly arranged;

the connecting end 31 extends out of the mounting hole and is movably limited on the fixed spanner body 1 through a clamp spring 5;

the square tenon sleeve 3 is provided with a vertically through spanner hole which is matched with the square tenon spanner 6;

the front end of the movable spanner body 2 is provided with an adjustable lip 21 matched with the fixed spanner lip 11; the tail end of the movable spanner body is provided with a rack 22 matched with the end of the gear 32; the rack 22 is engaged with the gear 32.

As shown in fig. 1, the square tenon wrench 6 is fixed in the square tenon sleeve 3, the opposite side of the bolt is positioned between the solid wrench lip 11 and the loose lip 21, the square tenon wrench 6 rotates counterclockwise, that is, the square tenon sleeve 3 also rotates counterclockwise, and the loose lip 21 moves towards the solid wrench lip 11 through the slide rail mechanism 4 (in the figure, the direction of the arrow on the loose lip 21 is the direction of tightening movement); until the bolt is clamped. After clamping, the bolt, the fixed spanner body 1, the movable spanner body 2, the square tenon sleeve 3 and the square tenon spanner 6 are integrated, and the rotation of the bolt in the counterclockwise direction is realized (the arrow direction on the bolt in the figure is the counterclockwise direction of the rotation of the bolt).
