One end of the operating handle 405 is fixed on the rotating shaft of the cam 406.

[0024] The design of the locking mechanism 4 is that when the power monitor needs to be installed, the power monitor can be installed on the mounting plate 1 by bolts, and then the mounting plate 1 is buckled into the bridge frame inside the electrical box, and the mounting plate 1 is connected and fixed to the bridge frame inside the electrical box through the locking mechanism 4. The whole process does not require the removal of the bridge frame inside the electrical box, nor does it require the removal of the back cover of the electrical box. The installation process is simple and convenient. When there is no power monitoring requirement or the power monitor needs to be replaced, the power monitor can be removed by operating the locking mechanism 4. For power monitors of different models and sizes, the position of the L-shaped hanging plate 3 on the mounting plate 1 can be adjusted to reserve operating space for the power monitor, which has a wider range of uses.

[0025] In this embodiment, the locking mechanism 4 also includes a telescopic rod 408, the bottom end of the telescopic rod 408 is fixed to the top end of the locking rod 401, and the top end of the telescopic rod 408 is fixed to the bottom end of the pressure rod 404; the telescopic rod 408 is used to provide a guiding function for the pressure rod 404, the locking rod 401, and the spring 403 to prevent the three from shifting their positions during movement.
