SUMMARY

[0003] In order to overcome the defects in the prior art, the utility model provides a clutch control structure of mechanical clutch transmission shaft, by arranging the spring in the outside of the control arm, the overall thickness formed by the shell and the control arm is reduced, so that the overall thickness of clutch transmission shaft structure is smaller, the size of the spring is no longer limited by the inside space of the control arm, and the larger installation space in the outside also avoids the wear between the spring and the control arm in the use process.

[0004] TECHNICAL SCHEME

[0005] A clutch control structure of mechanical clutch transmission shaft, including the control arm of rotation connection in the shell, be provided with spring connection end on the control arm, spring connection end with Fixedly connected with the control spring of being located in the outside of the control arm between the shell.

[0006] Further, the control arm includes a rotating connection end, the rotating connection end penetrates and is rotatably connected to the shell.

[0007] Further, the shell is provided with two fixed bolts, one end of the control spring is connected to one of the fixed bolts.

[0008] Further, the fixed bolt is also penetrated by a pressing piece, and the fixed bolt limits one end of the control spring through the pressing piece and the outer surface of the shell.

[0009] Further, the control arm is also provided with a control end for controlling the swing of the control arm by external force.

[0010] ADVANTAGEOUS EFFECTS

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] By setting the spring outside the control arm, the overall thickness formed by the shell and the control arm is reduced, so that the overall thickness of the clutch transmission shaft structure is smaller, the space occupation is reduced, at the same time, the size of the spring is no longer limited by the internal space of the control arm, a larger spring can be used, and the wear between the spring and the control arm in the use process is avoided due to the larger external mounting space, and the service life of the spring is increased. BRIEF DESCRIPTION OF DRAWINGS

[0013] Fig. 1 It is a structure schematic view of the clutch control structure of the mechanical clutch transmission shaft of the utility model.

[0014] Fig. 2 It is a structure principle schematic view of the control engagement tooth of the utility model.

[0015] REFERENCE NUMERALS

[0016] Control arm 1, rotating connection end 11, spring connection end 12, control end 13, mounting portion 14, pressing piece 2, fixed bolt 3, control spring 4, push piece 5, engagement tooth 6, shell 7. DETAILED DESCRIPTION

[0017] In order to better illustrate the content of the utility model, the following will be expanded and described in combination with the drawings and the embodiment:

[0018] There are Figs. 1-2 As shown in the utility model discloses a kind of clutch control structure of mechanical clutch transmission shaft, including rotating connection in shell 7 control arm 1, spring connection end 12 is provided on the control arm 1, spring connection end 12 and shell 7 between fixed connection have the control spring 4 located in the outer side of control arm 1.

[0019] Further, the control arm 1 includes a rotating connection end 11, and the rotating connection end 11 penetrates and is rotatably connected to the shell 7.

[0020] Further, the shell 7 is provided with two fixed bolts 3, and one end of the control spring 4 is connected to one of the fixed bolts 3.

[0021] Further, the fixed bolt 3 also penetrates the pressing piece 2, and the fixed bolt 3 limits one end of the control spring 4 through the pressing piece 2 and the outer surface of the shell 7.

[0022] Further, the control arm 1 is also provided with a control end 13 for controlling the swinging of the control arm 1 by external force.

[0023] Further, the rear side of the rotating connection end 11 is provided with a mounting portion 14, and the mounting portion 14 is provided with a push piece 5 for controlling the movement of the engagement tooth 6.

[0024] Specifically, by swinging the control arm 1 to the side away from the spring 4 through an external force, the push piece 5 is deflected, and the engagement tooth 6 is moved to engage, so as to realize power transmission. When the external force is removed, the control arm 1 will be deflected to the side where the spring 4 is located under the elastic force of the spring 4, and then the engagement tooth 6 is driven by the push piece 5 to disengage, so as to realize power disconnection, and achieve the effect of clutching.

[0025] The spring 4 is arranged outside the control arm 1, which reduces the overall thickness of the housing 7 and the control arm 1, so that the overall thickness of the clutch transmission shaft structure is smaller, the space occupation is reduced, and the size of the spring 4 is no longer limited by the internal space of the control arm 1. A larger spring can be used, and the larger external mounting space also avoids the wear between the spring 4 and the control arm 1 during use, and increases the service life of the spring 4.

[0026] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the technical solutions of the present application have been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or replace some of the technical features with equivalent ones; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
