Abstract

The invention provides a telescopic extension rod. The telescopic extension rod comprises a handle trigger assembly and a pulling rod; one end of an outer pipe is connected with the handle trigger assembly in an inserting mode, and a quick clamp assembly is installed at the other end of the outer pipe; one end of a telescopic pipe is installed in the outer pipe in a penetrating mode, a connecting seat is installed at the other end of the telescopic pipe, and a supporting pipe is installed on the connecting seat in an inserting mode; one end of a pulling assembly is located in the supporting pipe, and the other end of the pulling assembly is located in the connecting seat; a threaded rod is installed in the telescopic pipe, and the end of the threaded rod is connected with the pulling assembly in a linkage mode; a clamping assembly is installed in the telescopic pipe, the threaded rod is sleeved with a clamping seat, one ends of clamping claws are hinged to the clamping seat, the thread ends are installed at the other ends of the clamping claws, and two hinge pieces are hinged to the other ends of the clamping claws; and the pulling rod is located in the telescopic pipe, one end of the pulling rod is connected with the handle trigger assembly in a linkage mode, and the other end of the pulling rod is hinged to the two hinge pieces. The telescopic extension rod has the beneficial effects that the structure is reasonable, a spraying gun can be effectively controlled to spray after the telescopic extension rod stretches out or draws back, and the telescopic extension rod is extremely reliable when being used.

Description

technical field [0001] The invention belongs to the technical field of spray gun accessories and relates to a telescopic extension rod. Background technique [0002] The extension rod is a part applied to the spray gun. Since the spray gun needs to be sprayed to a high place, it is necessary to use the extension rod to increase the spraying distance of the spray gun. [0003] At present, extension rods can be divided into long extension rods and short extension rods according to their length. As the name suggests, long extension rods are longer extension rods. Attach the long extension rod to the end of the spray gun. [0004] For example, a kind of application number is the Chinese patent of 201110275104.X, discloses a kind of spray gun extension operating handle, comprises spray gun fixing device, telescoping rod, handle frame, wrench and pull cord, is provided between described spray gun fixing device and telescopic rod A fixed connection seat, one end of the fixed conn...
