[0009] In this way, the bolt passes through the center of the indicator disc, the center of the adjustment disc and the transmission shaft in sequence, so that the center of the indicator disc is fixedly connected with the center of the adjustment disc, and the indicator disc and the adjustment disc are firmly fixed on the boss of the transmission shaft.
[0010] As an implementation mode of the utility model, the outer ring of the indicating disc is fixed on the adjusting disc by screws.
[0011] In this way, the indicating disc rotates a certain angle around the center relative to the adjusting disc to complete the initial angle calibration of the transmission shaft. The corresponding positions of the second through hole of the indicating disc and the first through hole of the adjusting disc are fixed by screws.

[0056] According to some embodiments of the present application, please refer to Figures 1 to 7 The present embodiment relates to a manual mechanism for adjusting the angle of an indicating disk, comprising a first bracket 1, a second bracket 2, a transmission shaft 4, an adjusting disk 5 and an indicating disk 6, wherein the second bracket 2 is located above the first bracket 1; the transmission shaft 4 passes through the first bracket 1 and the second bracket 2; the adjusting disk 5 is arranged on the transmission shaft 4, and two or more first through holes 51 are evenly distributed around the circumference of the adjusting disk 5; the indicating disk 6 is installed above the adjusting disk 5, the center of the indicating disk 6 is aligned with the center of the adjusting disk 5, and two or more second through holes 61 are evenly distributed around the circumference of the indicating disk 6, the number of the first through holes 51 and the second through holes 61 are not equal, the distance between the first through hole 51 and the center of the adjusting disk 5 is equal to the distance between the second through hole 61 and the center of the indicating disk 6, and the aperture sizes of the first through hole 51 and the second through hole 61 are adapted; the indicating disk 6 rotates relative to the adjusting disk 5 to calibrate the initial angle of the transmission shaft 4, and an indicating mark 62 is provided on the indicating disk 6 to indicate the rotation angle of the transmission shaft 4.
[0057] The indicating disc 6 of the technical solution of the present application is superimposed on the adjusting disc 5 and can rotate freely. The angle between the adjacent first through holes 51 of the adjusting disc 5 and the angle between the adjacent second through holes 61 of the indicating disc 6 form a certain angle difference. The angle difference is used for angle calibration. The indicating disc 6 uses the angle difference to rotate relative to the adjusting disc 5. When it rotates to the initial angle, the indicating mark 62 indicates the corresponding position. The transmission shaft 4 rotates according to the indicating mark 62 to complete the initial angle calibration of the transmission shaft 4. Then the adjusting disc 5 and the indicating disc 6 are fixed, and the transmission shaft 4 rotates a certain angle to adjust the opening and closing of the switch. The angle of the indicating disc 6 is adjusted by the adjusting disc 5. The structure is simple and reliable, and the adjustment is convenient. The corresponding number of first through holes 51 and second through holes 61 are set according to the actual required accuracy. It can be fine-tuned and is suitable for various manual release mechanisms.
[0058] The adjusting disk 5 can be set to be circular, the radius of the adjusting disk 5 is smaller than the radius of the indicating disk 6, the indicating disk 6 covers the surface of the adjusting disk 5, when the center of the indicating disk 6 is aligned with the center of the adjusting disk 5, the circular cross section formed by the first through hole 51 on the adjusting disk 5 overlaps with the circular cross section formed by the second through hole 61 on the indicating disk 6, during the rotation of the indicating disk 6, the projections of the second through hole 61 and the first through hole 51 can form a relationship of separation, tangency, intersection and overlap, the entire circumferential angle is 360°, the first through hole 51 and the second through hole 61 are evenly distributed on the circumference, the angle between the adjacent first through hole 51 and the adjacent second through hole 61 can be obtained by the number of the first through hole 51 and the second through hole 61, and thus the angle difference can be calculated. According to the angle difference, the indicating disk 6 rotates relative to the adjusting disk 5, the center remains unchanged, the positional relationship of the second through hole 61 of the indicating disk 6 relative to the first through hole 51 of the adjusting disk 5 changes relatively, the initial angle is adjusted, the outer edges of the indicating disk 6 and the adjusting disk 5 are also fixed, and the positions of the indicating disk 6 and the adjusting disk 5 remain relatively unchanged. Rotate the transmission shaft 4 again, the indicating disc 6 and the adjusting disc 5 rotate at the same angle, rotate to the opening angle, and output the opening signal. The closing and opening angles are between 31° and 40°.

[0062] According to some embodiments of the present application, optionally, a bolt is provided at the center of the indicator disc 6 , and the bolt is used to fix the center of the indicator disc 6 on the adjustment disc 5 and the transmission shaft 4 .
[0063] In this way, the bolt passes through the center of the indicator disc 6 , the center of the adjustment disc 5 and the transmission shaft 4 in sequence, so that the center of the indicator disc 6 is fixedly connected to the center of the adjustment disc 5 , and the indicator disc 6 and the adjustment disc 5 are firmly fixed on the boss of the transmission shaft 4 .
[0064] According to some embodiments of the present application, optionally, the outer ring of the indicator disc 6 is fixed to the adjustment disc 5 by screws.
[0065] In this way, the indicating disc 6 rotates a certain angle around the center relative to the adjusting disc 5 to complete the initial angle calibration of the transmission shaft 4. The corresponding positions of the second through hole 61 of the indicating disc 6 and the first through hole 51 of the adjusting disc 5 are fixed by screws. The screws are not easy to fall off, the indicating disc 6 is not easy to shift, and the indication is accurate.
[0066] According to some embodiments of the present application, optionally, the adjusting disk 5 is provided with twelve first through holes 51 , and the indicating disk 6 is provided with eleven second through holes 61 .
[0067] Thus, the rotation angle between adjacent first through holes 51 of the adjusting disk 5 is 30°, the rotation angle between adjacent second through holes 61 of the indicating disk 6 is 32.72°, and the angle difference is 2.72°. The calibration can be accurate to 2.72°, and the calibration accuracy is high.
[0068] Observe the entire indicator disk 6 and the first through holes 51 and the second through holes 61 of the adjustment disk 5. When a group of first through holes 51 and second through holes 61 overlap, the angle between the indicator mark 62 line and the horizontal line of the center of the indicator disk 6 is 43.97°.
