[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figure 1-6 shown, the present utility model has the following specific embodiments.

[0029] Embodiment:

[0030] A multi-stroke motion mechanism includes a driving gear 1, a transmission gear 2, a long-stroke driven gear 3, and a short-stroke driven gear 4.

[0031] A shaft hole one 101 is provided on the driving gear 1.

[0032] A shaft hole two 201 and a positioning pin 202 are provided on the transmission gear 2.

[0033] A chute one 301 and a shaft hole three 303 are provided on the long-stroke driven gear 3, and a ball bearing one 302 is provided inside the shaft hole three 303.

[0034] A chute two 401 and a shaft hole four 403 are provided on the short-stroke driven gear 4, and a ball bearing two 402 is provided inside the shaft hole four 403.

[0035] Specifically, the transmission gear 2, the long-stroke driven gear 3, and the short-stroke driven gear 4 are coaxial, and the transmission gear 2 is located between the long-stroke driven gear 3 and the short-stroke driven gear 4.

[0036] The driving gear 1 and the transmission gear 2 are meshed and connected to each other.

[0037] One end of the positioning pin 202 extends to slide inside the chute one 301, and the other end of the positioning pin 202 extends to slide inside the chute two 401.

[0038] The arc length of the chute one 301 is greater than the arc length of the chute two 401.

[0039] The working principle of the present utility model:

[0040] When the driving gear 1 rotates clockwise by 1° to 90°, the driving gear 1 can drive the transmission gear 2 to rotate counterclockwise. At the same time, the shaft hole two 201 on the transmission gear 2 moves along the chute one 301 on the long-stroke driven gear 3 and the chute two 401 on the short-stroke driven gear 4. At this time, neither the long-stroke driven gear 3 nor the short-stroke driven gear 4 rotates.

[0041] When the driving gear 1 rotates clockwise by 90° to 180°, the driving gear 1 can drive the transmission gear 2 to rotate counterclockwise. At this time, the second shaft hole 201 moves to the stroke apex of the second chute 401 on the short-stroke driven gear 4, thereby driving the short-stroke driven gear 4 to rotate counterclockwise. At this time, the short-stroke driven gear 4 does not rotate.

[0042] When the driving gear 1 rotates clockwise by 180° to 360°, the driving gear 1 can drive the transmission gear 2 to rotate counterclockwise. At this time, the second shaft hole 201 moves to the stroke apex of the first chute 301 on the long-stroke driven gear 3, thereby driving the short-stroke driven gear 4 to rotate counterclockwise. At this time, both the long-stroke driven gear 3 and the short-stroke driven gear 4 rotate.

[0043] Through this design, different strokes and action times can be achieved when the gears rotate, that is, through the mutual cooperation among the driving gear 1, the transmission gear 2, the long-stroke driven gear 3, and the short-stroke driven gear 4. Thus, without changing the module of the gears, when rotating clockwise, this gear train has three gear strokes, namely the 360° stroke, the 270° stroke, and the 180° stroke. And this stroke can be changed according to the actual lengths of the first chute 301 and the second chute 401.

[0044] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific implementation manners. Obviously, according to the content of this specification, many modifications and variations can be made. This specification selects and specifically describes these embodiments to better explain the principle and practical application of the present utility model, so that those skilled in the relevant technical field can well understand and utilize the present utility model. The present utility model is only limited by the claims and their full scope and equivalents.
