[0054] A method for using a new type of wrench, used for the instructions for using the above-mentioned new type of wrench, is characterized in that it at least includes the following steps:

[0055] S1: Rotate the rotating block 201 on the screw 301 to rotate the clamping block 302 to a wider position in the limiting groove 202, thereby releasing the limiting fixation of the bolt 301 and the short rod 601;

[0056] S2: The second spring 7 pushes the short rod 601 to move downward in the limiting sleeve 101, thereby causing the shaft gear 602 to leave the sleeve gear 102, thereby releasing the limiting connection between the limiting sleeve 101 and the short rod 601;

[0057] S3: The mobile wrench is a hexagonal screwdriver bit that is engaged with the lower end of the short rod 601 and is engaged with the screw to be disassembled;

[0058] S4: the shaft gear 602 leaves the sleeve gear 102, and the hexagonal rod 401 is rotated to drive the limiting sleeve 101 to rotate on the short rod 601, so that the horizontal position of the handle can be adjusted without affecting the short rod 601;

[0060] S6: Rotating the hexagonal rod 401 and the extension rod 5 can drive the hexagonal screwdriver bit on the short rod 601 to rotate, so as to disassemble and assemble the screws.

[0061] Working principle: When using the new wrench, first rotate the rotating block 201 on the screw 301, so that the clamping block 302 rotates to a wider position in the limiting groove 202, and the limiting fixation of the screw 301 and the short rod 601 is released. The second spring 7 pushes the short rod 601 to move downward in the limiting sleeve 101, so that the shaft gear 602 leaves the sleeve gear 102, and the limiting connection between the limiting sleeve 101 and the short rod 601 is released. The hexagonal rod 401 and the extension rod 5 are rotated on the short rod 601, and the hexagonal rod 401 can be adjusted. The horizontal angle of the rod 401 and the extension rod 5, pressing the hexagonal rod 401 and the extension rod 5 downward drives the limit sleeve 101 to move downward, so that the sleeve gear 102 moves downward and meshes with the shaft gear 602, so that the limit sleeve 101 is limitedly connected with the short rod 601, and the extension rod 5 is pulled to move on the hexagonal rod 401 to adjust the length of the handle.
