the handle 202 rotates coaxially with the drive shaft 102 to allow the positioning structure 1021 to be movably switched between a brake-off position and a non-brake-off position:

in the non-opening position, the positioning structure 1021 is limited between the positioning groove 2031 and the locking structure 204, so that the cabinet door 101 is locked outside the electric control cabinet;

in the open position, the positioning structure 1021 is disengaged from the locking structure 204, so that the cabinet door 101 opens the electric control cabinet.

As an example, the connection socket 201 is mounted on the cabinet door 101 with the side of the connection socket 201 facing the outside of the cabinet door 101 in the assembled state as the outside and the side of the connection socket 201 facing the inside of the cabinet door 101 as the inside.

The arc-shaped groove 2012 accommodates the first elastic element 2015, is used for limiting the first elastic element 2015 and guiding the movement of the first elastic element 2015, and avoids the compression displacement and deformation of the first elastic element 2015.

As an example, a first resilient element 2015 is provided having a first free end and a second free end, the first free end of the first resilient element 2015 being connected to the handling portion 2043, the second free end of the first resilient element 2015 being abutted to an end of the arcuate slot 2012 remote from the locking structure 204. Of course, according to practice, it is not excluded to provide a stopper such as a latch on the handling portion 2043 to limit the first elastic member 2015 between the handling portion 2043 and the arc-shaped groove 2012. Further, according to practice, it is not excluded to fix the second free end of the first resilient element 2015 to the arcuate slot 2012 in the form of an adhesive, a weld, a plug, a snap, or the like.

Specifically, to make the whole more attractive, the blocking member 206 may be provided corresponding to the shape of the handle 202, and the blocking member 206 is at least partially blocked out of the lock hole 2021 when in the first position.

Optionally, the stopper 206 is provided with a stopper 2061 on both sides, so that the stopper 206 is wedged into the clamping groove 2013 via the stopper 2061 when in the second position, and because the connecting seat 201 is fixed to the cabinet door 101, when the stopper 2061 is wedged into the clamping groove 2013, the handle 202 is limited in the positioning groove 2031 to lock the handle 202, prevent the handle 202 from rotating in the padlock state, and further optimize the locking function of the circuit breaker handle 200. In addition, flanges may be provided on both sides of the handle 202 corresponding to the stopper 2061, so that the stopper 2061 may be mounted and the locking groove 2013 may be blocked, thereby making the whole more attractive.

In one embodiment, there are two stops 206, with two stops 206 being oppositely disposed on opposite sides of the handle 202. Further, a middle connection structure such as a connection base may be used to connect the two stoppers 206 into an integrally formed structure. Two stops 206 are located partially within the connecting seat 201 via a central connecting structure. As an example, mounting grooves 2014 are formed on both opposite sides of the handle 202, such that the two stoppers 206 extend out of the connecting base 201 through the mounting grooves 2014 and are disposed on both opposite sides of the handle 202.

In an embodiment, the bottom of the blocking member 206 is provided with a second elastic member 207, and the second elastic member 207 is in contact with the positioning structure 1021 for driving the blocking member 206 to return from the second position to the first position.

The second elastic member 207 is provided to drive the blocking member 206 to reset, so that the blocking member 206 is automatically blocked outside the lock hole 2021 in an ungapped state, so that the whole is more attractive, and dust-proof and pollution-proof to a certain extent are achieved.

Further, two second elastic members 207 may be provided and disposed separately on both sides of the stopper 206.

It should be noted that, the first elastic member 2015 and the second elastic member 207 may be configured as any elastic structures suitable for practical use, such as compression springs and torsion springs, according to practical needs. Of course, the first elastic member 2015 and the second elastic member 207 may be configured to have a certain elasticity, and the material of the first elastic member 2015 and the second elastic member 207 may be metal, rubber, plastic, or the like having a certain elasticity.

As an example, in the electric state, the transmission shaft 102 of the circuit breaker handle 200 is continuously moved in one of the clockwise direction or the counterclockwise direction in a manner similar to the stepwise rotary motion, so that the circuit breaker handle 200 is in the closing state or the opening state. In an electric state, the handle 202 is driven to rotate by the transmission shaft 102, so that automatic switching-on and switching-off are realized. In the manual state, by applying an external force to the handle 202, manual closing and opening are realized.
