Embodiment
By particular specific embodiment, embodiments of the present invention are described below, person skilled in the art scholar the content disclosed by this specification can understand other advantages of the present invention and effect easily.
Notice, structure, ratio, size etc. that this specification institute accompanying drawings illustrates, content all only in order to coordinate specification to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the present invention, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the present invention can produce and the object that can reach, all should still drop in scope that disclosed technology contents can contain.Simultaneously, quote in this specification as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the present invention.
As shown in Figure 1, Lever type clutch mechanism of the present invention, comprises bracing wire 2, stationary axle 1, spline housing 7 and shifting block 5, and the two ends of bracing wire 2 are each passed through the top of stationary axle 1 and the top of shifting block 5, and the bottom of stationary axle 1 is fixed in rear cover of box 10.What the bracing wire 2 between stationary axle 1 and shifting block 5 is provided with the first elastic structure 4, first elastic structure 4 employing is tension spring, and bracing wire 2 is provided with lock bolt 3 through one end of stationary axle 3, and the other end of bracing wire 2 is connected with the handle on extraneous handle rack.Shifting block 5 fixedly mounts in rear cover of box 10 by locating stud 6, bracing wire 2 pulls shifting block 5 to rotate around locating stud 6, and the bottom of shifting block 5 is stirred spline housing 7 and moved, and lock bolt 3 can adjust mobile in bracing wire 2, when avoiding pulling bracing wire 2, bracing wire 2 departs from stationary axle 1 simultaneously.
As shown in Figure 1, it is tension spring that one end of spline housing 7 is provided with the second elastic structure 8, second elastic structure 8, and the second elastic structure 8 promotes spline housing 7 and resets.Spline housing 7 coordinates with transmission shaft 9 to be installed, and transmission shaft 9 can adopt worm screw, and transmission shaft 9 stretches in spline housing 7.Annex connection mouth 11 place in rear cover of box 10 is provided with the spline housing with spline housing 7 corresponding matching, stirs the spline housing that spline housing 7 is mated be separated and engage by shifting block 5.Second elastic structure 8 is set on transmission shaft 9, and the end of spline housing 7 is withstood in one end of the second elastic structure 8, and when shifting block 5 does not prop up spline housing 7, elastic structure 8 promotes spline housing 7 and is moved to the left and engages with another spline housing.
