[0031] By the attached Figure 4 As shown, in this embodiment, the pushing frame 53 includes a support plate and a locking plate. The support plate is fixedly installed on the side of the pushing block 52, and the locking plate is vertically installed at the end of the support plate. The support plate is slidably connected to the sliding groove, and the locking plate is slidably connected to the matching groove 54. During use, through the installation and use of the support plate, the locking plate can slide synchronously with the pushing block 52. When the shaking handle 3 is rotated to the target position, the support plate drives the locking plate to move, allowing the locking plate to enter the matching groove 54, and the protruding part of the locking plate is used to be stuck in the matching groove 54 to achieve the locking of the angle of the shaking handle 3 itself.

[0032] By the attached Figure 3 As shown, in this embodiment, the locking mechanism 5 also includes a spring group 55, which is fixedly installed inside the pushing groove 51, and the end of the spring group 55 is fixedly connected to the bottom end of the pushing block 52. When the pushing block 52 drives the pushing frame 53 to enter the matching groove 54, the spring group 55 is in a released state. During use, through the use of the spring group 55, when the pushing block 52 moves toward one end of the rocker arm of the rocking handle 3, the spring group 55 is in a force storage state. When the user's hand leaves the surface of the pushing block 52, the spring group 55 will release its accumulated elasticity, pushing the pushing block 52 to the side away from the rocker arm of the rocking handle 3, providing power for the movement of the pushing frame 53.

[0033] By the attached Figure 5 As shown, in this embodiment, the mating groove 54 includes an annular rotation groove and a locking groove. An annular rotation groove is opened inside the circuit breaker mating component 2, and the annular rotation groove is rotatably connected to the push frame 53. A locking groove is opened inside the circuit breaker mating component 2, and two groups of locking grooves are provided, and the locking grooves are connected to the annular rotation groove. During use, the opening of the annular rotation groove assists the rocking handle 3 and the transmission end 4 to rotate stably, which is convenient for controlling the opening and closing of the circuit breaker inside the equipment. When the locking groove is opened, when the locking plate enters the locking groove, the locking plate will fix the position of the rocking handle 3 and the transmission end 4 itself, thereby realizing the function of preventing accidental touch.

[0034] By the attached Figure 6As shown, in this embodiment, the locking mechanism for the drawer unit of the electrical cabinet also includes a limiting mechanism 6, and the limiting mechanism 6 includes a steering groove 61, a connecting groove 62 and a limiting component 63. The top of the pushing block 52 is symmetrically provided with a steering groove 61, and the upper end of the pushing block 52 is provided with a connecting groove 62. The two groups of steering grooves 61 are connected through the connecting groove 62. The limiting component 63 is rotatably installed inside the shaking handle 3. During use, the limiting component 63 is rotated to adjust the angle of the end component of the limiting component 63 to ensure that the end component of the limiting component 63 can fit the connecting groove 62 and move from one group of steering grooves 61 to the inside of another group of steering grooves 61, so as to lock the position of the pushing block 52 itself.

[0035] By the attached Figure 7 As shown, in this embodiment, the limiting assembly 63 includes a rotating frame 631, a rotating rod 632 and a limiting plate 633. The rotating rod 632 is rotatably mounted on the side of the shaking handle 3, the rotating frame 631 is fixedly mounted on the top of the rotating rod 632, and the limiting plate 633 is fixedly mounted on the bottom of the rotating rod 632. The limiting plate 633 is rotatably connected to the steering groove 61, and the limiting plate 633 is slidably connected to the connecting groove 62. In use, by rotating the rotating frame 631, driven by the rotating rod 632, The angle of the limit plate 633 itself is adjusted. When the limit plate 633 is rotated to the target angle, the limit plate 633 can slide along the connecting groove 62, so that the pushing block 52 can move stably inside the pushing groove 51. When the pushing block 52 moves to the target position, the rotating frame 631 is rotated again so that the overall angle of the limit plate 633 is perpendicular to the connecting groove 62. At this time, the limit plate 633 cannot pass through the connecting groove 62 to enter the other set of steering grooves 61, thereby locking the position of the pushing block 52 itself.

[0036] By the attached Figure 7 As shown, in this embodiment, a calibration groove is provided on the upper surface of the rotating frame 631, and the overall angle of the calibration groove is consistent with the angle of the limit plate 633 itself. During use, the opening of the calibration groove makes it convenient for the user to identify the angle of the limit plate 633 itself inside the shaking handle 3 according to the angle and direction of the calibration groove.
