[0062] The body 1 comprises a first end 11 and a second end 12. The first driving head 2 comprises a first seat 21 and a first ratchet 22. The first seat 21 is pivotally arranged on the first end 11 by a first pivot axis 81. The first ratchet 22 is rotatably arranged on the first seat 21 by a first rotation axis 91. The first rotation axis 91 and the first pivot axis 81 are intersected. The second driving head 3 comprises a second seat 31 and a second ratchet 32. The second seat 31 is pivotally arranged on the second end 12 by a second pivot axis 82. The second pivot axis 82 and the first pivot axis 81 are transversely arranged. The second ratchet 32 is rotatably arranged on the second seat 31 by a second rotation axis 92. The second rotation axis 92 and the second pivot axis 82 are not intersected.

[0063] As can be seen from the above, the first driving head 2 and the second driving head 3 have completely different swing area directions, can have various different swing angles, and can further generate more use combinations by matching the different rotation directions of the first ratchet 22 and the second ratchet 32, and can be fully applied to various different environments.

[0064] Preferably, one of the first end 11 and the second end 12 is concavely provided with a set of connecting spaces 121, and the other has an outer contour comprising two flat surfaces 111. One of the first seat 21 and the second seat 31 is pivotally connected to the set of connecting spaces 121, and the other is pivotally clamped against the two flat surfaces 111. The first end 11 and the second end 12 are connected to the first seat 21 and the second seat 31 by a concave-convex structure, which can help the assembler to quickly identify the difference and ensure that the body 1 has a certain structural strength.

[0065] In the embodiment, the first driving head 2 further comprises a first pivot 23 connected to the first seat 21 and the first end 11 along the first pivot axis 81. The second driving head 3 further comprises a second pivot 33 connected to the second seat 31 and the second end 12 along the second pivot axis 82. Figure 3 As shown, when the second rotation axis 92 and the first pivot axis 81 are parallel to each other, the second driving head 3 does not exceed the first driving head 2 in the extension direction of the first pivot axis 81, and the user can have more choices by the structural difference of different thicknesses and different sizes.

[0066] Further, the first driving head 2 further comprises a first adapter 5, which is arranged in the first ratchet 22 in a same rotation relationship with the first rotation shaft 91 as the center, and is used to connect with a member to be rotated (such as a sleeve).
