Abstract

The invention provides a clamp traction device in a stretchable extension rod. The clamp traction device comprises a traction assembly, a screw, a clamping assembly and pull rods; the traction assembly comprises a traction rope, a first connecting rod and a second connecting rod which are sequentially connected; the end of the screw is connected with the second connecting rod; the clamping assembly comprises a clamping base, at least two clamping claws and at least two hinge sheets, the clamping base is arranged outside the screw in a sleeving manner, one end of each clamping claw is hinged to the other end of the clamping base and is provided with a threaded end used for clamping the screw, and the hinge sheets are hinged to the other ends of the clamping claws; and the pull rods are hinged to the hinge sheets and used for driving the clamping claws to clamp the screw. The clamp traction device has the beneficial effects that the structure is reasonable, a spraying gun can be effectively controlled to conduct spraying after the clamp traction device stretches out or retracts back, and the clamp traction device is very reliable in use.

Description

technical field [0001] The invention belongs to the technical field of spray gun accessories, and relates to a clamping and pulling device in 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 connecti...
