[0023] Furthermore, the cross-section of the support plate 5 is "L"-shaped, the support plate 5 is plugged into the surface of the plug-in groove 7, the mounting plate 6 is abutted against the surface of the connecting plate 4, and two groups of engaging holes 8 are provided. The two groups of engaging holes 8 are opened on both sides of the support plate 5, and the plug-in groove 7 is opened on the mounting plate 6, so that the support plate 5 can be plugged into the surface of the plug-in groove 7, so as to realize the connection between the support plate 5 and the mounting plate 6, and then realize the installation of the time control switch body 1 on the connecting plate 4.

[0024] Furthermore, the cross-section of the mounting groove 9 is "L" and there are two groups of mounting grooves 9, which are opened on both sides of the mounting plate 6. Under the action of the mounting groove 9, the connecting spring 11, the limiting plate 12 and the rotating plate 14 can be placed on its surface for movement.

[0025] Furthermore, the diameter of the through hole 10 is the same as the diameter of the engaging hole 8, and the diameter of the through hole 10 is larger than the diameter of the engaging block 13. Under the action of the through hole 10, the engaging block 13 can be moved out of the mounting groove 9 through the through hole 10 and engage with the surface of the engaging hole 8.

[0026] Furthermore, one end of the connecting spring 11 is fixedly connected to the surface of the mounting groove 9, and the other end of the connecting spring 11 is fixedly connected to the surface of the limiting plate 12. The limiting plate 12 is abutted against the surface of the mounting groove 9. Under the action of the connecting spring 11, a supporting force is provided on the surface of the limiting plate 12 to push the limiting plate 12 to slide on the surface of the mounting groove 9, thereby achieving the locking effect of the limiting plate 12 and the locking hole 8.

[0027] Furthermore, the surface of the engaging block 13 is hemispherical, and the engaging block 13 is engaged with the surface of the engaging hole 8 through the through hole 10. A rotating groove is provided inside the rotating plate 14. Under the connection between the engaging hole 8 and the engaging block 13, the connection between the support plate 5 and the mounting plate 6 is limited, so that the installation of the time switch body 1 is more stable.

[0029] Working principle: When installing the time-controlled switch body 1, first, the mounting plate 6 fixed on the time-controlled switch body 1 is pressed against the surface of the connecting plate 4, and slides along the surface of the connecting plate 4, so that the support plate 5 can be plugged and connected to the surface of the plug-in groove 7 to achieve the lateral limit of the time-controlled switch body 1. At this time, the rotating plate 14 is bent toward the direction of the time-controlled switch body 1, so that the rotating plate 14 rotates around the rotating shaft 15 as the center, thereby driving the limiting plate 12 and the engaging block 13 to rotate into the mounting groove 9. At this time, the connecting spring 11 is in a compressed state. When the support plate 5 and the mounting plate 6 are connected, the rotating shafts 15 on both sides are released. Under the action of the supporting force provided by the connecting spring 11, the limiting plate 12 is pushed to press against the surface of the mounting groove 9, and the engaging block 13 is engaged through the through hole 10 and the surface of the engaging hole 8, thereby completing the installation of the time-controlled switch body 1.
