In other embodiments, the relative height between the cup 121 and the adjusting rod 123 can be adjusted by a threaded screw pair or a threaded connection, and when the accuracy requirement for adjusting the light source assembly 20 is not high, the user can also adjust the height difference between the two adjusting rods 123 by directly moving the adjusting rod 123. It can be understood that the height difference between the two adjusting rods 123 is adjusted by rotating the pin cup 121, so that the position of the lamp is adjusted, and the light emitting angle of the lamp is adjusted by the angle adjusting device 10, so that the light emitting range of the lamp is wider, and a larger adjusting angle is realized.

Further, the lamp body housing 110 has a limiting structure, and it is understood that the limiting structure is configured to limit the swinging angle of the fixing block 111 relative to the connecting arm 122, thereby limiting the rotation range of the lamp body housing 110 relative to the lamp pin assembly 120. Specifically, the limiting structure may be configured as a stop portion fixed to the lamp body housing 110, and when the lamp body housing 110 swings to a preset angle, the stop portion abuts against the connecting arm 122, so as to limit further rotation of the lamp body housing 110 relative to the lamp foot assembly 120; the limiting structure may also be disposed at the rotation axis of the fixing block 111 or the connecting arm 122 to directly limit the rotation angle of the fixing block 111 relative to the connecting arm 122, so as to limit the light emitting angle of the light source assembly 20.

It will be appreciated that the mounting bolt 141 penetrates the fixing block 111 and the connection arm 122 as a rotation shaft, and the fastening degree between the fixing block 111 and the connection arm 122 is adjusted by rotating the mounting nut 142, so that the sensitivity of adjusting the light emitting angle of the rotary lamp body housing 110 is changed. Meanwhile, the detachable connection between the mounting bolt 141 and the mounting nut 142 facilitates the later maintenance and replacement operations of the stopper or lamp foot assembly 120.

Referring to the drawings, a first washer 143 is provided between the mounting bolt 141 and the ear plate, and a second washer 144 is provided between the second belleville spring 132 and the mounting nut 142. In this embodiment, the first gasket 143 and the second gasket 144 are each provided as a flat gasket.
