The rotating wheel disc 104 and the stirring piece are distributed at intervals, and the radius of the rotating wheel disc 104 is smaller than that of the first cylinder.

The edge of the rotating wheel disc 104 is provided with four strip-shaped grooves 104a which are in one-to-one correspondence with the four poke rods 103, the four strip-shaped grooves 104a are distributed at equal intervals along the circumferential direction of the rotating wheel disc 104, the length direction of each strip-shaped groove 104a is the radial direction of the rotating wheel disc 104, the bottom of each strip-shaped groove 104a is in the shape of an arc, the circumference where the circle center of each arc is located is a second circumference C2, the first circumference C1 is tangent to the second circumference C2, the distance between the axis of the rotating wheel disc 104 and the circle center of the first circumference C1 is equal to the sum of the radii of the first circumference C1 and the second circumference C2, and the rotating wheel disc 104 is used for being connected. The control assembly 2 is used to control the dial 102 to rotate 90 ° each time.

When one tap lever 103 is located at the opening of the strip-shaped groove 104a of the tap disk 102, another tap lever 103 adjacent to the same tap lever 103 is also located at the opening of another strip-shaped groove 104 a. Because the radius of the rotating wheel disc 104 is smaller than that of the first cylinder, when the rotating wheel disc 104 rotates, the space between the two connecting rods 1021 is enough to pass through the rotating wheel disc 104, the rotating wheel disc 104 and the toggle disc 102 cannot collide with each other, and the stable gear shifting is ensured.

It should be noted that, because the bottom of the strip-shaped groove 104a on the rotary wheel disc 104 is arc-shaped, and can be attached to the outer wall of the tap lever 103, a relatively stable position between the strip-shaped groove 104a of the rotary wheel disc 104 and the tap lever 103 is a position where the tap lever 103 is completely attached to the bottom of the strip-shaped groove 104a, or a position where the strip-shaped lever is located at an opening of the strip-shaped groove 104 a. With these two positions as the initial positions of the rotary plate 104 and the dial plate 102, the shift position is more accurate.

Referring to fig. 3, the control assembly 2 may include a displacement sensor 201 and a controller 202, the displacement sensor 201 and a connecting rod 1021 are distributed at intervals, and when one end of one connecting rod 1021 is located at the bottom of the strip-shaped groove 104a, the displacement sensor 201 is opposite to the other end of the same connecting rod 1021, or when one end of one connecting rod 1021 is located at the opening of the strip-shaped groove 104a, the displacement sensor 201 is opposite to the other end of the same connecting rod 1021. The controller 202 is configured to cut off power to the drive motor 101 when the displacement sensor 201 is aligned with the other end of one of the link rods 1021.

The displacement sensor 201 and a connecting rod 1021 are distributed at intervals, when one end of one connecting rod 1021 is positioned at the bottom of the strip-shaped groove 104a, the displacement sensor 201 is opposite to the other end of the connecting rod 1021, or when one end of the same connecting rod 1021 is positioned at the opening of the strip-shaped groove 104a, the displacement sensor 201 is opposite to the other end of the connecting rod 1021. The displacement sensor 201 can be opposite to the other end of the connecting rod 1021 when the rotary wheel 104 is at two stable shifting positions to generate a signal, and the controller 202 can be matched with the displacement sensor 201 to cut off the power supply of the driving motor 101, so that the driving motor 101 does not work any more, and the accuracy of the shifting positions is also maintained. The gear shifting accuracy of the damping oil cylinder gear shifting mechanism can be further improved.

It should be noted that the displacement sensor 201 and the other end of the connecting rod 1021 may generate a contact or separation signal, and the controller 202 may be electrically connected to the displacement sensor 201, and cut off the power supply of the driving motor 101 according to the contact or separation signal generated by the displacement sensor 201. The present disclosure is not so limited.
