Description

Technical Field

[0001] The utility model belongs to the technical field of lighting devices, and particularly relates to a rotatable bracket of a floodlight. Background Art

[0002] In the prior art, after searching, it was found that a Chinese patent disclosed "an adjustable floodlight bracket", and its announcement number is "CN209196618U". This patent mainly rotates the handle to make the worm drive the worm wheel to rotate, so that the floodlight rotates and adjusts the irradiation angle of the floodlight. The floodlight bracket is highly adjustable and can adjust the position and irradiation angle of the floodlight as needed, and has a wide range of applications.

[0003] However, when the worm gear has a self-locking characteristic, although it can provide stability and safety in some situations, such as preventing reversal, it will indeed limit the flexibility of adjustment to a certain extent. Specifically, because of the existence of the self-locking characteristic, it may lead to obstacles when reverse adjustment or rapid and flexible changes in transmission status are required. For example, when you want to quickly change the transmission direction or perform more frequent and complex adjustment actions, self-locking may make these operations difficult or even impossible to achieve.
