Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Referring to fig. 1 to 3, the ring-shaped member 8 is fixed on the power shaft 1, the blocking piece 4 is sleeved on the power shaft 1, one end of the return spring 3 abuts against the ring-shaped member 8, and the other end of the return spring abuts against the blocking piece 4, so that upward return force is provided for the ring-shaped member 8 and the power shaft 1. One end of the power shaft 1 is provided with a special-shaped boss 11 (see figure 5) which corresponds to the special-shaped groove 21 on the push plate 2 (see figure 4), when the special-shaped boss 11 is matched with the special-shaped groove 21, the torque can be transmitted, and once the special-shaped boss and the special-shaped groove are separated, the torque can not be transmitted. The push plate 2 can rotate around the axis of the power shaft 1.

In the electric operation state, the power shaft 1 is acted by the reset force of the reset spring 3, so that the special-shaped boss 11 of the power shaft 1 is always in a state of being engaged with the special-shaped groove 21 of the push plate 2 (see figure 4). When the push plate 2 is driven by external power to rotate, the push plate 2 can drive the power shaft 1 to rotate, and the power shaft 1 drives the switching mechanism shaft 9 to rotate.

When needing manual operation, power axle 1 is pushed down by the external force of manual application, compresses reset spring 3, makes the dysmorphism boss 11 of power axle 1 break away from (see fig. 3) with the dysmorphism groove 21 of push pedal 2, and manual rotation power axle 1 this moment, push pedal 2 can not driven, and manual operation power can not carry out the transmission of force through push pedal 2 promptly.

In addition, the end surface of the special-shaped boss 11 of the power shaft 1 is provided with a chamfer so as to play a guiding role when the power shaft 1 is jointed with the push plate 2, and the clutch is further convenient.

In particular, in the present embodiment, the shaped boss 11 has a gear-like structure with 4 protruding teeth 111, and correspondingly, the shaped slot has four corresponding gear-like slots 211. In fact, for the purpose of the present invention, the special-shaped boss 11 may also adopt other forms of structures, for example, the number of the teeth 111 may be 1, 2, 3, or any number of them, and the shape of the teeth may also be changed as long as the special-shaped boss 11 and the special-shaped groove 21 can be matched with each other and can transmit torque.

In addition, it should be noted that the present invention has the following advantages: by adjusting the characteristics of the special-shaped boss and the special-shaped groove, the power shaft 1 and the push plate 2 can only be jointed at a specific angle, similar to the key unlocking principle. If the modified boss 11 of the present embodiment is a cross boss, by designing the length of each tooth 111 (boss) to be different in size, the gear-shaped groove 211 of the corresponding modified groove 21 is also different in length and matched in length to the tooth 111. In this way, the special-shaped boss 11 can only be matched with the special-shaped groove 21 at a certain angle, and can be changed into joint from staggered layers under the action of the return spring 3. The advantages of this design are: 1. the foolproof design is adopted, so that the assembly of workers is facilitated; 2. the user uses the logic aspect to avoid the mismatch of manual operation and electric operation: for example, when the user manually switches the switch to the "open" state, the external power stays in the "close" state of the switch, and the clutch can engage and transmit the torque force without the above structural design, so that when the external power is driven to switch from "close" to "open", because the switch is switched to open by the user, the switch stroke is exceeded by rotating in the opening direction again, and the switch is damaged.

The structure, proportion, size, etc. shown in the attached drawings of the above embodiments of the present invention are only used for matching with the contents disclosed in the specification, so as to be known and read by the people familiar with the art, not for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and the modification of any structure, the change of proportion relation or the adjustment of size should still fall within the range that the technical contents can be covered without affecting the function that the present invention can produce and the purpose that can be achieved. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle", "clockwise", "counterclockwise", etc. used in the present specification are for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are considered to be the scope of the present invention without substantial changes in the technical content.
