[0024] As a technical optimization scheme of the utility model, the limiting component one 200 includes the slide rod one 201, the slide rod one 201 is slidably connected inside the handle 101, the slide rod one 201 top is fixed with the limit block one 202, when the limit block one 202 moves, will drive the slide rod one 201 to move, the slide rod one 201 one end is fixed with the spring one 203, the spring one 203 passes through the elastic force, can make the top rod one 204 insert into the ratchet one 105, the slide rod one 201 other end is fixed with the top rod one 204, and the top rod one 204 end is a corner, and one is concave arc, to make the ratchet one 105 only unidirectional rotation, when reversely rotating, will be blocked by the corner.

[0025] As a technical optimization scheme of the utility model, the limiting component two 300 includes the slide rod two 301, the slide rod two 301 is slidably connected inside the handle 101, the slide rod two 301 top is fixed with the limit block two 302, the slide rod two 301 end is fixed with the spring two 303, the spring two 303 passes through the elastic force, can make the top rod two 304 insert into the ratchet two 106, the slide rod two 301 bottom is fixed with the top rod two 304, and the top rod two 304 end is opposite the top rod one 204 end.

[0026] As a technical optimization scheme of the utility model, the pulling component 400 includes the handle 401, the handle 401 one side is fixed with the connecting rod 402, the connecting rod 402 is rotatably connected inside the handle 101, the connecting rod 402 end is fixed with the limit sheet 403, the limit sheet 403 prevents the connecting rod 402 from being pulled out of the handle 101, the handle 401 one side is provided with the hanging hole 404, the handle 401 inside is fixed with the spring three 405, the spring three 405 passes through the elastic force, can make the insertion rod 407 insert into the handle 101, the spring three 405 end is fixed with the limit plate 406, the limit plate 406 one side is fixed with the insertion rod 407, after the insertion rod 407 inserts into the handle 101, can prevent the handle 401 from rotating when moving the handle 401.

[0027] In use, the bolt is inserted into the sleeve hole 104, and then the handle 401 is gripped and rotated. Assuming the top block 108 is pressing against the first limiting block 202, the first sliding rod 201 will compress the first spring 203, causing the top rod 204 to be pulled out from the ratchet 105. This allows the second top rod 304 to be inserted into the second ratchet 106 under the elastic force of the second spring 303. Therefore, the wrench can only be used to tighten the bolt when rotated in one direction. To switch directions, simply push the pressing rod 107 in the opposite direction, causing the top block 108 to slide from the first limiting block 202 side to the first limiting block. The second 302 side causes the slide bar second 301 to compress the spring second 303 and pull the push rod second 304 out of the ratchet second 106. At the same time, the elastic force of the spring first 203 is released, so the slide bar first 201 drives the push rod first 204 to insert into the ratchet first 105. Thus, the wrench can only turn the bolt in the opposite direction. Therefore, in this way, the purpose of switching directions can be quickly achieved. In addition, the wrench can effectively change the position of the lever arm by using the certain angle relationship between the handle 401 and the grip 101, thus achieving the purpose of saving effort when turning the bolt.
