Clamp

Abstract

The clamp comprises a clamping suite used for clamping an object and a connector used for supporting the clamping suite, and when the clamping suite rotates from the vertical direction to the transverse direction, a rotary clamping mechanism directly / indirectly drives a left clamping arm and a right clamping arm to further move in the opposite direction; and when the clamping suite rotates from the transverse direction to the vertical direction, the driving of the rotary clamping mechanism to the left clamping arm and the right clamping arm is relieved. The connector comprises a rotating part rotationally connected with the clamping sleeve and a fixing part used for being connected with an object, and the main body part or the geometric center of the fixing part and the rotating center of the clamping sleeve are eccentrically arranged. Compared with a non-eccentric structure, the clamp provided by the utility model has the advantages that the eccentric structure can greatly reduce the torque transmitted to the fan blade at the air outlet of the automobile, so that the fan blade at the air outlet is prevented from being damaged.

Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a clamp. Background Art

[0002] A phone stand is a device used to support and secure a phone so that it can rest stably on a table, countertop, or other flat surface. Phone stands are typically made of sturdy materials (such as metal or plastic) and have an adjustable design to accommodate different phone sizes and angles.
