[0005] Preferably, the right end of the adjusting shaft extends through and to the outer end of the right-side fixed seat, where a first gear is fixed by screws. An internal gear ring is meshed with the outer side of the first gear, and an external gear ring is integrally formed and connected to the outer side of the internal gear ring. The external gear ring meshes with the transmission gear.

[0006] Preferably, spacer rings are placed at equal intervals on the inner end of the fixed base, and second docking bosses are integrally formed and symmetrically connected at both ends of the spacer rings. Cam rings are fitted on the second docking bosses and the first docking bosses.

[0007] Preferably, a transmission gear ring is integrally formed inside the cam ring, and a second gear is meshed on the transmission gear ring. The second gear is fixed to the corresponding adjusting shaft by screws.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: the external gear ring of this utility model is meshed with the transmission gear, and the external gear ring can be easily driven to rotate by the transmission gear; the outer side of the first gear is meshed with the internal gear ring, and the first gear can be easily driven to rotate by the internal gear ring; the second gear is fixed to the corresponding adjustment shaft by screws, and the second gear can be easily driven to rotate by the adjustment shaft; in summary, this utility model can easily and uniformly adjust the cam trigger angle, effectively improving work efficiency.

Detailed Implementation

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] like Figure 1-3 As shown, a cam switch structure based on overall adjustment includes an operating shaft 1. Limiting plates 2 are symmetrically mounted and fixed at both ends of the operating shaft 1 using screws. A fixing seat 3 is placed inside the limiting plate 2 and is fixedly connected to the operating shaft 1 using screws. The fixing seat 3 is provided with a first mating boss 4, a transmission gear 5, and an adjusting shaft 6. The first mating boss 4 is integrally formed and connected to the outer side of the inner end of the fixing seat 3. The transmission gear 5 is mounted and fixed to the outer side of the right side of the fixing seat 3 using screws. The adjusting shaft 6 is rotatably connected to the inner end of the fixing seat 3 in a ring shape, and the right end of the adjusting shaft 6 extends through and to the outer side of the right side of the fixing seat 3. The first gear 7 is fixed to the end by screws. An internal gear ring 8 is meshed with the outside of the first gear 7. An external gear ring 9 is integrally formed and connected to the outside of the internal gear ring 8. The external gear ring 9 is meshed with the transmission gear 5. Spacer rings 10 are placed at equal intervals inside the fixed base 3. The two ends of the spacer ring 10 are integrally formed and symmetrically connected with second mating bosses 11. Cam rings 12 are fitted on the second mating bosses 11 and the first mating bosses 4. A transmission gear ring 13 is integrally formed and connected inside the cam ring 12. A second gear 14 is meshed with the transmission gear ring 13. The second gear 14 is fixed to the corresponding adjusting shaft 6 by screws.

[0015] Specific usage: After the cam ring 12 is displaced, remove the right limit plate 2, then loosen the screw on the transmission gear 5. At this time, the transmission gear 5 can be rotated easily. Then, tighten the transmission gear 5 to drive the outer gear ring 9 to rotate. The rotation of the outer gear ring 9 drives the inner gear ring 8 to rotate. The rotation of the inner gear ring 8 drives the first gear 7 to rotate. The rotation of the first gear 7 drives the adjusting shaft 6 to rotate. The rotation of the adjusting shaft 6 drives the second gear 14 to rotate. The rotation of the second gear 14 drives the corresponding cam ring 12 to rotate for angle adjustment. Finally, tighten the screw on the transmission gear 5 to lock the inner gear ring 8.

[0016] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
