[0034] In order to more clearly describe the technical content of the present invention, further description is given below in conjunction with specific embodiments.

[0035] The utility model discloses a built-in connection structure of a lamp, which includes a connection member assembly, wherein the connection member assembly includes an upper connection member 3-3, a lower connection member 3-4, a clamping spring 3-2, and a clamping screw 3-1. The lower connection member 3-4 is installed on the upper connection member 3-3 and connected by a connecting shaft. The clamping spring 3-2 is fixed to the upper connection member 3-3 by the clamping screw 3-1. The clamping spring 3-2 presses the lower connection member 3-4 and limits the lower connection member 3-4, so that the lower connection member 3-4 and the upper connection member 3-3 can rotate relative to each other.

[0036] As a preferred embodiment of the utility model, the end of the lower connecting member 3-4 has two protruding shafts, the interior of the upper connecting member 3-3 has two semicircular recessed holes, the protruding shafts are coaxial with the semicircular recessed holes, the lower connecting member 3-4 and the upper connecting member 3-3 cooperate with each other through the protruding shafts and the semicircular holes, and realize a certain angle of rotation.

[0037] As a preferred embodiment of the present utility model, the connecting shaft of the upper connecting member 3-3 and the lower connecting member 3-4 is arranged inside.
