Description

Technical Field

[0001] The present application relates to the technical field of stage lamps, and in particular to a synchronous belt anti-fracture structure and a stage lamp. Background Art

[0002] The moving head lights in stage lighting fixtures are usually equipped with driving wheels and transmission wheels to transmit the moving head movement.
