As shown in fig. 6 and 8, when the street lamp is in the state shown in fig. 1, that is, when the street lamp is bent toward one side, the motor 31 is started to push the output end 35 to move upward, so as to drive the rubber column 32 to move upward, and further drive the limiting column 33 on the rubber column 32 to move upward together. The stopper post 33 moves upward in the stopper groove 37 in accordance with the shape of the groove. Since the position-limiting post 33 is made of a rigid material (e.g., stainless steel or rigid plastic), the position-limiting post 33 itself will not deform, and thus the rubber post 32 will be driven to change along with the shape and depth of the position-limiting groove 37. When the rubber column 32 moves to the top of the limit groove 37, the control unit controls the motor 31 to stop working (the length of the output end 35 can be set to be exactly the same as the moving length of the limit groove 37). The rubber column 32 will drive the upper lamp column part 20 to move and tilt relative to the lower lamp column part 10 in the process of gradually moving and tilting. In one embodiment, a connecting block 34 may be disposed between the rubber column 32 and the lamp column upper portion 20, and the rubber column 32 and the lamp column upper portion 20 are fixedly connected by the connecting block 34.
