Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-9 The present invention provides an embodiment of a locking structure for an electric operating mechanism, comprising:

[0034] The housing 1 has a bottom plate 4 on one side of its outer surface, and the housing 1 is provided with a locking structure through the bottom plate 4;

[0035] The circuit breaker 15 has a locking knob 5 provided on one side thereof. The circuit breaker 15 is connected to the housing 1 through the bottom plate 4 . The locking knob 5 on the circuit breaker 15 is connected to the locking structure on the housing 1 .

[0036] The user can use the locking structure to drive the locking knob 5 on the circuit breaker 15 to rotate, so that the circuit breaker 15 can be in the "locked" or "automatic" state. Since the locking structure is set on the base plate 4, there is no need to modify the internal components of the mechanism and the circuit breaker 15 itself.

[0037] In this embodiment, the locking structure on the base plate 4 includes a rivet 3 and a lever 6, and a guide groove 10 is provided in the middle position of one side of the lever 6. The base plate 4 is slidably connected to the lever 6 through the cooperation between the rivet 3 and the guide groove 10. A handle 2 is installed at the bottom of the other side of the lever 6, and a flat washer 7 and a spring 8 are installed on one side of the handle 2. The rivet 3 is fixedly installed on the base plate 4. When the lever 6 rotates with the lock knob 5 as the center point, the cooperation between the rivet 3 and the guide groove 10 can limit the rotation range of the lever 6, and the flat washer 7 limits the installation position of the spring 8. When the handle 2 drives the lever 6 to rotate, the handle 2 is in an active state on the lever 6, and when the handle 2 drives the lever 6 to move, it can avoid the handle 2 and the base plate 4 from getting stuck.

[0038] In this embodiment, an arc groove 12 is provided at the bottom end of one side of the base plate 4, and the handle 2 is slidingly connected to the base plate 4 through the arc groove 12. The arc groove 12 on the base plate 4 can further play a limiting role, cooperating with the rivet 3 to limit the rotation angle of the lever 6.

[0039] In this embodiment, the handle 2 is composed of a small diameter shaft 13 and a large diameter shaft 14 . The size of the small diameter shaft 13 is slightly smaller than that of the arcuate groove 12 , and the size of the large diameter shaft 14 is slightly larger than that of the arcuate groove 12 .

[0040] In this embodiment, a waist-shaped groove 11 is provided at the top of one side of the shift lever 6, and the shift lever 6 is connected to the lock knob 5 through the waist-shaped groove 11. During the rotation of the shift lever 6, the lock knob 5 can be driven to rotate on the circuit breaker 15, so that the circuit breaker 15 is in a "locked" or "automatic" state, and the connection between the lock knob 5 and the shift lever 6 is compact and reliable.

[0041] In this embodiment, a guide fixing hole 9 is provided at the bottom of one side of the shift lever 6, and the shift lever 6 is connected to the handle 2 through the guide fixing hole 9 and the small diameter shaft 13, and the shift lever 6 is rotationally connected to the handle 2 through the guide fixing hole 9 and the small diameter shaft 13.

[0042] Working principle: The user pulls the handle 2, and the flat pad 7 compresses the spring 8 as the handle 2 moves. After the user releases the handle, the spring 8 can drive the handle 2 to move, so that the handle 2 can be engaged with the arc groove 12, thereby locking the handle 2 in the position on the arc groove 12. When the user adjusts the state of the circuit breaker 15, the user releases the lock by pulling the handle 2, and then the user pushes the handle 2 to slide in the arc groove 12, driving the lever 6 to rotate with the lock knob 5 as the center of the circle, so that the waist-shaped groove 11 can drive the lock knob 5 to rotate, thereby putting the circuit breaker 15 into the "locked" or "automatic" state.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or scope of the present invention. Therefore, the embodiments of the present invention are illustrative and non-restrictive.
