The invention provides a telescopic rod. The telescopic rod comprises an outer pipe and an inner pipe, a nut sleeve, a lead screw sleeve and a locking mechanism, wherein the outer pipe and the inner pipe are connected together in a sleeving manner; the nut sleeve is pivoted on the outer pipe; the lead screw sleeve is arranged on the inner pipe in a sliding and sleeving manner and is in threaded connection with the nut sleeve; the locking mechanism is arranged at the opening end of the outer pipe; the locking mechanism comprises a plurality of elastic locking arms which are distributed annularly and a plurality of connecting rod assemblies; the elastic locking arms are connected with the lead screw sleeve through the corresponding connecting rod assemblies; the nut sleeve is rotated to drive the lead screw sleeve to be moved along the inner pipe so as to drive the all connecting rod assemblies to be moved, and locking heads of the all elastic locking arms are respectively connected withcorresponding clamping slots positioned on the outer wall of the inner pipe or separated from the corresponding clamping slots positioned on the outer wall of the inner pipe, so that locking or unlocking of the inner pipe is realized. The telescopic rod provided by the invention has the advantages that the telescopic rod is convenient to use, parts positioned on connection and locking parts can be replaced, and the service life is long.
Description
technical field [0001] The invention relates to a telescopic pole. Background technique [0002] At present, telescopic poles are used in many occasions, and the length of the telescopic poles can be changed according to different usage requirements, such as photographic equipment, selfie sticks, glass drying, mop handles, clothes poles, etc. Common similar products are usually made of different diameters. The straight tube is sleeved, and then fixed by buckle, bolt or threaded nut structure, so as to be fixed after elongation. The structure of buckle or bolt usually needs to open multiple holes on the inner tube, thus reducing the inner tube Therefore, when the inner tube protrudes too long, it is easy to bend or break, and the buckle structure is not allowed to be replaced, and the latch is easy to lose, which will cause inconvenience in use. When the threaded nut structure is used, the thread is usually set on the tube. After a long time of use, slippery wires are prone ...
