The tool 10 of the present invention includes a handle 20, a first driving rod 30, a second driving rod 40 and a third driving rod 50; wherein:

One end of the first driving rod 30 is fixedly connected to the handle 20 , and the first driving rod 30 axially extends along a virtual first driving axis L1 .

One end of the second driving rod 40 is fixedly connected to the handle 20 , and the second driving rod 40 extends axially along a virtual second driving axis L2 , which is not perpendicular to the first driving axis L1 .

The third drive rod 50 extends axially along a virtual third drive shaft L3, the third drive shaft L3 is not perpendicular to the first drive shaft L1 or the second drive shaft L2, the third drive rod 50 includes a Ratchet device 51 and a drive head 52, one end of this ratchet device 51 is connected with this handle 20, and this drive head 52 is connected with this end of this ratchet device 51 opposite to this handle 20, and this drive head 52 can be with this 3rd drive shaft L3 is the center that rotates relative to the handle 20 .

The ratchet device 51 is provided with a reversing member 511, the reversing member 511 can rotate relative to the handle 20 around the third drive shaft L3, and the reversing member 511 can change the relative direction of the driving head 52 to the handle 20 when the reversing member 511 rotates. Turning steering.

The first driving rod 30 is sleeved with a first sleeve 31, and the first sleeve 31 can rotate relative to the handle 20 around the first driving shaft L1. The second driving rod 40 is sleeved with a second The sleeve 41, the second sleeve 41 can rotate relative to the handle 20 around the second drive shaft L2.

The handle 20 is integrally formed, and the handle 20 is sleeved on one end of the first driving rod 30 , one end of the second driving rod 40 and one end of the ratchet device 51 by overmolding.

Through the above-mentioned structure, the tool 10 can provide a driving tool with a ratchet mechanism, and can correspond to various screws of different specifications.

With regard to the above, it can be concluded that the present invention has the following advantages:

1. It is a tool with ratcheting function according to the present invention, wherein the tool includes a handle, a first driving rod, a second driving rod and a third driving rod, one end of the first driving rod is fixedly connected to the handle, The first drive rod extends axially along a virtual first drive shaft, one end of the second drive rod is fixedly connected to the handle, the second drive rod extends axially along a virtual second drive shaft, and the second drive rod axially extends along a virtual second drive shaft. The drive shaft is not perpendicular to the first drive shaft, the third drive rod extends axially along a virtual third drive shaft, the third drive shaft is not perpendicular to the first drive shaft or the second drive shaft, the third drive shaft The lever includes a ratchet device and a drive head, one end of the ratchet device is connected to the handle, the drive head is connected to the end of the ratchet device opposite to the handle, and the drive head can be centered on the third drive shaft relative to the The handle is rotated, and the tool can provide a driving tool with a ratchet mechanism through the above-mentioned structure, and can correspond to screws of various specifications.

However, the above is only a preferred embodiment of the present invention, and should not be used to limit the implementation scope of the present invention, so all changes in numerical values or replacement of equivalent elements, or equivalents made according to the patent scope of the present invention Changes and modifications should still fall within the category covered by the patent of the present invention.
