In this embodiment, the outer frame 101 is fixed on the ceiling through the connecting piece 106 provided on it, and the inner frame 102 is connected to the lamp body 107 through the bracket 108. The elastic device 104 on the push rod 105 and the pressing piece 103 fixed on the upper end of the pushing rod 105, the pressing piece 103 is provided with convex teeth 111, the pressing piece 103 and the convex teeth 111 are integrally formed, the elastic device 104 can make the The protruding teeth 111 are provided between the ejector rod 105 and the pressing piece 103 so as to snap into the tooth grooves 110 of the outer frame 101 , and the tooth grooves 110 and the outer frame 101 are integrally formed. A sinking groove is provided at the bottom of the push rod 105 . In this embodiment, the elastic device 104 is a spring, and in other embodiments, the elastic device 104 may also be a spring ring or other elastic components.

The inner surface of the inner frame 102 is provided with a stepped hole, and the ejector rod 105 covered with the elastic device 104 is set in the stepped hole, and the elastic device 104 can slide up and down in the stepped hole; the pressing piece 103 is arranged on the top of the stepped hole, and the pressing The center of the sheet 103 is provided with a through hole with an internal thread, and the pressing sheet 103 is fixedly connected to the upper end of the ejector rod 105 through threads. The ejector rod 105 first passes through the elastic device 104, then passes through the stepped hole arranged on the inner surface of the inner frame 102, and then is fixedly connected with the pressure piece 103 by threads, and the ejector rod 105 can be inserted into the stepped hole of the inner frame 102 under the action of an external force.
