The operation handle of each embodiment of this utility model, middle operating mechanism crossed by the spring that can be used for this utility model embodiment.Middle operating mechanism crossed by the spring of this utility model embodiment, can have the operation handle of this utility model any embodiment.
The operation handle of first embodiment:
As depicted in figs. 1 and 2, the operation handle of this utility model first embodiment, including union joint 1 and handle body 2, and two parts are independently arranged, and are not fixedly connected.Wherein, handle body 1 includes connecting housing 11 and connecting shaft 12, and handle body 2 then can include grip part 20, kink 21, transition part 22, jam 23, connecting portion 24 and boss 25.Boss 25 therein is arranged on the periphery of connecting portion 24, and in the present embodiment, as shown in Figure 4, boss 25 is a pair, including the first boss 251 and the second boss 252, is oppositely arranged on the excircle of connecting portion 24.
Wherein, connecting shaft 12 is quadrangular shape, is indirectly connected with the spring of this utility model embodiment by operation axle and change-speed gearing and crosses the main shaft of middle operating mechanism.On four ribs of quadrangular, can have chamfering.Connecting shaft 12 is also not necessarily limited to be quadrangular shape, as long as connected mechanism can be driven to rotate, it is achieved and any shape that main shaft is indirectly connected with.
And connect the outer surface preferably face of cylinder of housing 11, but it is not limited thereto, it is also possible to be other shape, such as quadrangular, six prisms etc..And connect the inner face of housing 11, it is substantially round cylinder.In the present embodiment, according to the clockwise direction shown in Fig. 3, inner face is sequentially formed with the first fin the 110, first groove the 111, second fin 112 and the second groove 113.First groove 111 and the second groove 113 therein, it is circular groove, it is respectively used to the revolution space rotated in a circumferential direction within connecting housing 11 for the first boss 251 and the second boss 252 along connection housing 11, first boss 251 rotates to the end of the first groove 111 in the first housing 11, the most all assume it is to turn clockwise, the end of the first groove 111 namely the second fin 112, the band housing 11 that is dynamically connected rotates, namely drives union joint 1 to rotate.Preferably, the side of fin 111,113 and the side male-female engagement of boss 251,252.
