[0024] In the specific work, the cylinder drives the transmission block 2 to advance forward, so that the transmission frame 3 also continuously advances forward, the connecting column 4 is connected with the trapezoidal frame 5 and the transmission frame 3 at the same time, so that the connecting column 4 moves under the limitation of the limiting inclined groove 51, the connecting column 4 moves from the front end to the end of the limiting straight groove 31, and moves from the beginning to the end of the limiting inclined groove 51, thereby driving the transmission frame 3 to move downward, and the trapezoidal frame 5 moves to the inclined inner side, because the right angle edge on the trapezoidal frame 5 is perpendicular to the position of the transmission frame 3, the trapezoidal frame 5 is always perpendicular to the transmission frame 3, and the area formed by the centers of the two is a rectangle and continuously reduces in motion, when the inner side of the transmission frame 3 and the inner side of the straight edge of the trapezoidal frame 5 contact with the two end faces of the fixed seat perpendicular to the fixed seat, it will push it to the limiting mechanism 7 fixedly installed on the bottom plate 1, the cylinder drives the transmission block 2 to continuously advance, until the fixed seat no longer moves, that is, the positioning can be completed;

[0025] The installation angle of the limiting mechanism 7 is forty-five degrees, and it is installed on the diagonal line of the rectangular area formed by the straight edge of the transmission frame 3 and the trapezoidal frame 5;
