The second locking structure 30 is provided with a second elastic member 31, one end of the second elastic member 31 abuts against the second locking structure 30, and the other end of the second elastic member 31 abuts against the second limiting member 90. When the second locking structure 30 is driven to move toward the inside of the housing 210, the second locking structure 30 will press the second elastic element 31 onto the second limiting element 90; when the second locking structure 30 loses the driving force applied by the rope member 40, the second elastic member 31 will return to its original elastic state to bring the first locking structure 20 back to the locking state.

Specifically, the first elastic member 21 and the second elastic member 31 may both adopt a spring structure such as a compression spring; the first limiting member 80 and the second limiting member 90 can be both limiting plates, the limiting plates are arranged at the inner side of the shell 210 and correspond to the positions of the first locking structure 20 and the second locking structure 30 respectively, and are installed and fixed by a limiting bracket 81 arranged on the shell 210; the first locking structure 20 and the second locking structure 30 are respectively assembled on the corresponding limiting plates, so that the first locking structure 20 and the second locking structure 30 can only move in the direction limited by the limiting plates (i.e. the direction perpendicular to the housing 210), and the telescopic movement switching of the first locking structure 20 and the second locking structure 30 is ensured; the first locking structure 20 and the second locking structure 30 both include a thimble structure and a cap disposed at one end of the thimble structure, the compression spring is sleeved on the thimble structure, the cap is disposed on the thimble structure having one end of the compression spring, and opposite ends of the compression spring abut against the cap and the first limiting part 80 or the second limiting part 90 respectively. When the ejector pin structure moves towards the inner side of the shell 210, the ejector pin structure drives the cap to move towards the limiting plate, so that the pressure spring is compressed between the cap and the limiting plate; when the thimble structure loses the drive power, the pressure spring will assist the thimble structure to return to the initial state according to self elasticity.

Referring to fig. 1 and fig. 3, in one embodiment, the turning brackets 501 are disposed parallel to the limiting brackets 81, and at least one of the turning brackets 501 coincides with the central axis of the corresponding limiting bracket 81. When the first limiting member 80 and the second limiting member 90 are fixedly mounted by using the limiting bracket 81, because the turning structure 50 is located at a side of the first limiting member 80 and the second limiting member 90 away from the housing 210, the limiting bracket 81 for fixedly mounting the first limiting member 80 and the second limiting member 90 can coincide with a central axis of the turning bracket 501 for fixedly mounting the turning structure 50, that is, the turning bracket 501 and the limiting bracket 81 are the same bracket structure, and the limiting bracket 81 extends towards the turning structure 50 and forms the turning bracket 501. It is understood that, according to the actual layout, each steering bracket 501 and the corresponding limiting bracket 81 may be the same bracket structure, or a part of the steering brackets 501 and the corresponding limiting brackets 81 may be the same bracket structure.

Referring to fig. 1 to fig. 3, in a second aspect, the present embodiment further provides a movie lamp 200, including a light source assembly and the cassette unlocking device 100 as described above; the coupling bayonet 221 is disposed around the light source assembly. The video lamp 200 provided by the embodiment of the application comprises the cassette unlocking device 100, and the control assembly of the cassette unlocking device 100 adopts the rope piece 40 and the steering bracket 501 to control the first locking structure 20 and the second locking structure 30 to move and unlock, and the rope piece 40 is simpler than other mechanical transmission assemblies (such as gear transmission), so that the structure of the video lamp 200 is effectively simplified, and the production cost of the video lamp 200 is further reduced.

The present application is intended to cover various modifications, equivalent arrangements, and adaptations of the present application without departing from the spirit and scope of the present application.
