The setting of the triangular convex strip 701 can increase the resistance to the movement of the resistance pad 7, thereby ensuring the position of the resistance pad 7 in the absence of external force and maintaining the stability of the position of the lighting lamp 1.

[0023] Specifically, the lateral adjustment component 4 includes a fixed rod 401 connected to the fixed plate 3, a fixed tube 402 is movably sleeved on the outer side of the fixed rod 401, and the cross-sectional shapes of the fixed rod 401 and the fixed tube 402 are both square, and a socket 403 is penetrated through the side walls of the fixed rod 401 and the fixed tube 402, and a plurality of sockets 403 are provided on the fixed rod 401, and a pin 404 is inserted between two corresponding sockets 403; the cooperation between the fixed rod 401 and the fixed tube 402 facilitates the adjustment of the length therebetween, and the cooperation between the socket 403 and the pin 404 can fix the adjusted position, thereby facilitating the adjustment of the distance between the lighting lamp 1 and the blackboard.
