[0008] As a preferred embodiment of this utility model, the shape and size of the outer edge of the positioning plate are adapted to the shape and size of the inner wall of the slide groove. A slide rod is fixedly mounted on the side of the positioning plate, and a positioning rod is fixedly mounted on the side of the slide rod. A positioning groove is opened on the outer edge of the positioning rod, and the shape and size of the outer edge of the positioning groove are adapted to the shape and size of the inner wall of the positioning cylinder.

[0009] As a preferred embodiment of this utility model, an adjusting rod is fixedly mounted on the outer edge of the positioning cylinder, an adjusting groove is provided on the outer edge of the outer cylinder, and the inner wall of the adjusting groove is slidably connected to the side of the adjusting rod. A second spring is fixedly connected to the side of the inner wall of the outer cylinder, and the end of the second spring away from the inner wall of the outer cylinder is fixedly connected to the side of the positioning cylinder.

[0010] As a preferred embodiment of this utility model, a threaded ring is fixedly sleeved on the outer edge of the outer cylinder, and a nut is threadedly connected to the outer edge of the threaded ring.

There are two wrench head bodies, and the side of the two wrench head bodies has the same connection structure as the two sides of the handle.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This manual wrench with a detachable head uses a sliding cylinder and a positioning plate in conjunction to move the positioning plate along the inner wall of the groove. This helps the side of the positioning plate push the circular plate into the inner wall of the groove. Then, the wrench head body is rotated, which in turn drives the positioning plate to rotate through the positioning rod and the sliding rod. Spring 1 then pushes the circular plate to move in the inner wall of the groove. The circular plate then pushes the outer edge of the positioning plate to align with the inner wall of the slot for positioning. This also helps the adjacent sides of magnet 1 and magnet 2 to attract each other, thus facilitating the easy installation of the wrench head body.

[0013] 2. This manual wrench with a detachable head uses a positioning cylinder and an adjusting rod in conjunction. Moving the adjusting rod within the adjusting groove moves the positioning cylinder, thus assisting in the setup of the wrench head. Releasing the adjusting rod then allows the spring to push the positioning cylinder, aligning its inner wall with the inner wall of the positioning groove. This, along with the positioning cylinder and rod, limits the wrench head's position. Rotating the nut further restricts the movement of the adjusting rod by rotating it along the outer edge of the threaded ring until the sides of the nut and the inner wall of the adjusting groove limit the adjustment rod's position, ensuring stable setup of the wrench head.
