Abstract

The invention provides a multi-section automatic telescopic rod which comprises a motor, n-stage transmission mechanisms and (n+1) coaxial sleeves, wherein n is greater than and equal to 2. The motoris arranged on one end of the first sleeve. The first transmission mechanism comprises a first screw rod and a first nut. The outer circumference wall of the first nut is connected with the second sleeve. The motor uses the first transmission mechanism to drive the second sleeve to carry out linear motion. The a-th transmission mechanism is arranged inside the a-th sleeve. The a-th transmission mechanism comprises a a-th screw rod and a a-th nut. One end of the a-th screw rod is connected with one side of a (a-1)-th nut. When a (a-1)-th screw rod drives the a-th screw rod to carry out synchronization rotation, the (a-1)-th nut drives the a-th screw rod to carry out linear motion. The outer circumference wall of the a-th nut is connected with a (a+1)-th sleeve. The (a-1)-th screw rod uses the a-th transmission mechanism to drive the (a+1)-th sleeve to carry out linear motion, wherein a is equal to 2,..., n. According to the invention, the telescopic rod has automatic extension and contraction functions, and is stably positioned at any position through easy and convenient operation with one hand.

Description

technical field [0001] The invention relates to a telescoping rod structure, more specifically to a multi-section automatic telescopic rod. Background technique [0002] The telescopic rod is made of multi-section rods. It is widely used in people's daily life, especially when people use their mobile phones to take selfies. When shooting, the telescopic rod has played a big role, making it easy to adjust the shooting distance. [0003] At present, the common telescopic rod structure, one is to use the damping parts between the rods to realize the positioning of the rods after they are stretched or contracted; positioning. Regardless of the structure, the extension and retraction of the telescopic rod requires manual operation, and the required length of the telescopic rod must be repeatedly adjusted during use, which cannot reach the length required by the user as soon as possible, which is time-consuming and laborious. Contents of the invention [0004] The purpose of ...
