The steering mechanism of the sexual ratchet device.

Nowadays, when the user installs and disassembles the small-sized object, most of the smaller-sized palm-type ratchet devices are used, and the palm-type ratchet device is used with a working tool (such as a sleeve), and the user holds the hand grip. Holding the palm-type ratchet device, and pressing the palm of the hand against the top of the palm-type ratchet device, the palm-type ratchet device drives the working tool to perform the bolt assembly and disassembly operation.

Please refer to FIG. 1 and FIG. 2 , which are schematic diagrams of the palm-type ratchet device 10 . The inside of the socket 11 is provided with a receiving groove 111 , and the inner ring ratchet 112 is disposed on the inner surface of the receiving groove. The control body 12 is internally equipped with a latching latching block 13 and is equipped with a steering wheel 14 at the first end for directly controlling the offset of the latching block 13 and a fourth at the second end. The socket post 121 is sleeved with a sleeve working tool (not shown). The control body 12 is inserted into the receiving slot 111 of the socket 11 so that the socket post 121 protrudes from the sleeve. The bottom surface of the socket 11 and the one side of the latching block 13 engage the inner ring ratchet 112 of the socket 11, and the steering wheel 14 protrudes from the top surface of the socket 11 for user operation switching. In the direction of the force, the control body 12 is limited to the socket 11 by the buckle 15; in use, the ratchet device 10 is sleeved with a sleeve of the control body 12 to fit a sleeve (not shown) Used, since the ratchet device 10 is small in size, the user's hand can hold the seat 11 of the ratchet device 10, And pressing the palm to the steering wheel 14 on the top surface of the socket 11, and applying force to operate the socket 11 to rotate the sleeve by the socket column 121 of the control body 12, so that the sleeve performs the bolt assembly.
