Abstract

A focus wheel assembly (20), comprising a support (22), a focus plate (24) and a focus wheel (26); the support (22) includes a support seat (220) and a self-support seat (220) The mounting seat (222) formed by the external extension, the focus plate (24) and the focus wheel (26) are located on both sides of the mounting seat (222), and the focus wheel (26) passes through the mounting seat (222) The through hole (224) is rotatably connected with the focus plate (24); the support (22) is used to connect the external structure, the focus wheel assembly (20) is installed on the external structure through the support (22), and the focus wheel (26 ) is arranged partially through the outer structure when the support (22) is connected to the outer structure.

Description

【Technical field】 [0001] The invention belongs to the technical field of control, and in particular relates to a focus wheel assembly, a handheld device and a photographing system using the focus wheel assembly. 【Background technique】 [0002] The damping control knob can be widely used in industrial machinery and digital products, such as the controllers of camera equipment in the film and television industry, such as follow focus devices, rocking wheels, and somatosensory controllers, etc., which can adjust the fine position. Good control feel. [0003] At present, there are two types of follow focus wheel structures commonly used in follow focus devices: one is the follow focus wheel module attached to the electronic device, and the independent follow focus wheel module is connected to the electronic device through the interface; the other is the follow focus wheel structure and the handle or handheld The equipment adopts an integrated design. [0004] However, the exis...
