Patent Description:
Most of the existing handles for the hand-held gimbal stabilizer have the configuration of traditional straight-rod, which comprises an elongated column as well as an arrangement for mounting the camera and adjusting the gravity center, a handle and a counterweight which are arranged on the column from top to bottom. The self-weight of the stabilizer is heavy, and thus it will become much heavier after a camera is arranged thereon. While in the prior art the hand-held handles are either placed horizontally or vertically, the ways for holding the hand-held handles cannot be changed so as to meet the needs of the user, and in view of this the tired or fatigued sense raised by holding the handles in a single way cannot be reduced. Therefore, the current hand-held camera stabilizer will be greatly limited in its popularization and application.

<CIT> e.g. illustrates a handheld support. The handheld support can be a base support for a mounting platform. The mounting platform may include a mounting assembly and support assembly for supporting a payload. The handheld support can be configured to enable the mounting platform and a payload coupled to the mounting platform to be supported by a hand (or a pair of hands). The handheld support can include a support member, such as grip or handle. The handle may include a stand, which may be a structure capable of independently supporting the handheld support when placed on a surface. The handle may include an input interface. The input interface is depicted as a joystick or include buttons, keyboards, touch screens, and the like. The input interface may be positioned on the handle in a manner easily accessible by the fingers of the user. The input interface may be used to input control signals for controlling the support assembly and/or the payload, as well as other functionalities of the handheld support.

In view of the problems existing in the prior art, the invention provides a lightweight hand-held stabilizer, which increases the application modes of the stabilizer handle and enhances the experience of the stabilizer product for user.
