Further, the elastic element 10 is a spring or other structure such as a metal spring plate, preferably, as shown in fig. 2, the elastic element 10 disposed on the bottom end face of the first main body portion of the fixing base includes an elastic portion 101 and a pressing portion 102, the pressing portion 102 is fixedly connected to the elastic portion 101, when the fixing base 1 is connected to the connecting base 2, the elastic portion 101 is pressed by the protective cover, so that the pressing portion 102 of the elastic element 10 downwardly presses the bottom end face of the cavity of the connecting base 2, at this time, the elastic portion 101 is in a pressed state, and an axial acting force is generated between the fixing base 1 and the connecting base 2, so as to ensure that the connecting base does not move up and down and left and right relative to the fixing base after the lamp is installed. Further, the elastic element 10 is uniformly disposed at a position close to the first combining portion with the center of the bottom end surface of the first main body portion 1A as a center of circle or at a position close to the second combining portion with the center of the bottom end surface of the second accommodating cavity 2B of the connecting seat 2 as a center of circle. Further, the number of the elastic elements 10 corresponds to the number of the first or second coupling portions, and the elastic elements 10 are linearly arranged in a radial direction with both the first and second coupling portions.

When the fixing seat 1 is combined with the connecting seat 2, the convex block 3 of the fixing seat 1 is loaded from the opening end 51 of the U-shaped mounting groove 5, and rotates along the circumferential direction of the inner wall of the second accommodating cavity 2B until the limiting structure 52 rotating to the U-shaped mounting groove 5 is installed in place, namely, the first combining part of the fixing seat 1 is mechanically connected with the second combining part of the connecting seat 2.
Preferably, as shown in fig. 1, a height difference is provided between the limiting structure 52 and the open end 51 of the U-shaped mounting groove 5, and the limiting structure 52 is higher than the open end 51. When the lamp is installed, the connecting base 2 is pushed up, the axial acting force of the elastic element 10 on the connecting base 2 is overcome, the convex block 3 of the connecting base 2 is pushed to the position near the opening end 51 of the U-shaped mounting groove 5, then the convex block 3 enters from the opening end 51 of the U-shaped mounting groove 5, and the convex block rotates along the circumferential direction of the second accommodating cavity inner wall 2B until the convex block abuts against the inner side wall of the limiting structure 52. Because of the axial acting force of the elastic element 10, the connecting seat 2 axially moves towards the direction away from the fixing seat 1 until the top surface of the projection 3 of the fixing seat 1 is attached to the inner top surface of the limiting structure 52 of the connecting seat 2, so that the mechanical connection between the first combining part of the fixing seat 1 and the second combining part of the connecting seat 2 is realized. Afterwards, between fixing base 1 and connecting seat 2, because the produced axial effort of elastic element 10 exists always to and under the effect of lamps and lanterns self gravity, fixing base 1 and the mutual block of connecting seat 2 become more firm, the condition that the lamps and lanterns rocked about can not appear.

By arranging the hooking part 54, an operator needs to push up and then rotate the connecting base 2 to detach the lamp when detaching the lamp. Specifically, when it is necessary to separate the fixing base 1 and the connecting socket 2, the operator cannot directly separate the fixing base 1 and the connecting socket 2 by reversely rotating the connecting socket 2 because the hooking part 54 blocks the protrusion 3 from being directly removed from the U-shaped mounting groove 5 due to the presence of the hooking part 54. At this moment, an operator needs to push up the connecting seat 2, because the positions of the fixing seat 1 and the convex block 3 are fixed, the upward movement of the connecting seat 2 can cause the top surface of the convex block 3 which is originally attached to each other to be separated from the inner top surface of the limiting structure 52 of the U-shaped mounting groove 5, the opening end 51 of the U-shaped mounting groove 5 correspondingly moves to the position with the same height as the convex block 3, and then the connecting seat 2 is rotated reversely, so that the lamp can be detached. The configuration that the lamp can be detached by pushing up and then rotating the connecting seat 2 reduces the possibility that an operator detaches the lamp due to misoperation, reduces the possibility that children privately detach the lamp to cause danger, and improves the connection stability between the fixing seat 1 and the connecting seat 2 and the electricity utilization safety of the lamp.
