In other embodiments, the angle between the intermediate section 320 and the connection section 310 can also be other degrees, and the angle between the limiting section 330 and the intermediate section 320 can also be other degrees.

[0042] When the connection hook 300 needs to be hooked on the groove wall of the connection groove 2111, first drive the connection hook 300 to move into the connection groove 2111 until the limiting section 330 moves into the connection groove 2111; then drive the connection hook 300 to move downward until it can no longer move. At this time, the intermediate section 320 is placed on the installation frame 200; then drive the connection hook 300 to move away from the connection groove 2111 until the limiting section 330 contacts the groove wall of the connection groove 2111. At this time, the limiting section 330 will be hooked on the groove wall of the connection groove 2111.

[0043] When the connecting hook 300 needs to be withdrawn from the connecting groove 2111, first drive the connecting hook 300 to move upward until the limiting section 330 is misaligned with the groove wall of the connecting groove 2111; then drive the connecting hook 300 to move away from the connecting groove 2111, and the connecting hook 300 can be withdrawn from the connecting groove 2111. By adopting the connecting hook 300 in the present application, it is not only beneficial to smoothly install the control unit 100 on the installation frame 200, but also ensures the stability of the control unit 100 on the installation frame 200.
