Abstract
The utility model relates to a camera telescopic boom which comprises a base boom. A first telescopic boom and a second telescopic boom are sequentially arranged on the base boom, and the first telescopic boom is connected with the base boom through a first bolt rod. One end of the first bolt rod is fixed at the back end of the base boom, and the other end of the bolt rod is fixed on the back end of the first telescopic boom though a first nut. A first poking wheel is placed on the outer side of the first nut. The first telescopic boom is connected with the second telescopic boom through a second bolt rod. One end of the second bolt rod is fixed at the back end of the first telescopic boom through a second nut, and the other end of the bolt rod is fixed at the back end of the second telescopic boom through a third nut. A second poking wheel is arranged on the outer side of the second nut. The first poking wheel is meshed with the second poking wheel to control the first telescopic boom and the second telescopic boom to stretch and retract. Due to the fact that poking wheels rotates to control telescopic booms to stretch and retract, the stability and the shooting efficiency of shooting are improved and shooting cost is saved. The camera telescopic boom has the advantages of being simple in structure, convenient to operate, high in strength and good in stability.
