Embodiment Construction
[0009] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0010] As shown in Figure 1 and Figure 2, on a plane with equal thickness, there is a through hole with double centers A, B and radius R, r, and the extension line connecting the centers A and B intersects on the wall of the through hole near the handle end r If it is set as middle, one to twenty internal teeth 3 are arranged on the hole wall radially, left and right, and there is a ratchet 5 with a ring of teeth on the outer wall built into the through hole. Reciprocating movement, the teeth on the ratchet 5 can mesh with each tooth of the inner tooth 3, can rotate radially together in one direction and separate and can rotate independently. A handle 2 is connected to the radial outer wall of the through hole, the middle line of the handle 2 is the center line 1 of the handle, the center line 1 of the handle intersects the extension ...
