Telescopic rod and supporting equipment

The invention relates to the technical field of telescopic pipes, in particular to a telescopic rod and supporting equipment in order to solve the technical problem of unfirm connecting of telescopic pipes in the prior art. The telescopic rod comprises a first telescopic pipe, a second telescopic pipe set and a third telescopic pipe which are connected in sequence. The second telescopic pipe set is in threaded connection with the first telescopic pipe and can be partially stored in the first telescopic pipe. The third telescopic pipe is in threaded connection with the second telescopic pipe set and can be partially stored in the second telescopic pipe set. The technical problem of unfirm connecting of the pipes is solved. 本发明涉及伸缩管技术领域，尤其是涉及种伸缩杆及支撑设备。以缓解现有技术中存在的伸缩管的管道间连接不牢固的技术问题。包括依次连接的第伸缩管、第二伸缩管组和第三伸缩管。第二伸缩管组与第伸缩管螺纹连接并且能够部分收纳于第伸缩管内。第三伸缩管与第二伸缩管组螺纹连接并且能够部分收纳于第二伸缩管组内。本发明解决了管道间连接不牢固的技术问题。
