Coaxial telescopic high-altitude electric saw

Abstract

The present invention discloses a coaxial telescopic high-altitude electric saw including a main rod assembly, a telescopic rod assembly, a base assembly and a connecting assembly; the main rod assembly includes a main rod, one end of the main rod is provided with an inner sleeve, the end of the inner sleeve is provided with a spring guide rod and a spring, one end of the spring is provided with aguide sleeve, and the spring guide rod is sleeved by both the spring and the guide sleeve; the base assembly is disposed at one end of the main rod, the telescopic rod assembly sleeves the other endof the main rod, the telescopic rod assembly includes a telescopic rod sleeving the inside of the main rod, one end of the telescopic rod is provided with an engaging seat, two sides of the engaging seat are provided with limiting stop blocks matched with grooves, and the inside of the telescopic rod is provided with an inner telescopic rod; and the connecting assembly is disposed between the mainrod assembly and the telescopic rod assembly. Due to the arrangement of an overall structure, the length of a rod part of the high-altitude electric saw may be adjusted, so that the relative movementbetween the telescopic rod and the main rod is more smooth, the telescopic rod is convenient to fix, and convenience is brought for operation.

Description

technical field [0001] The invention relates to a high-altitude electric saw, in particular to a coaxial telescopic high-altitude electric saw. Background technique [0002] Tall trees need to trim high-altitude branches. Generally, workers climb to the tree and use manual saws to manually pull back and forth to saw off the branches that may be affected. The labor intensity is high, the work efficiency is low, and high-altitude operations exist Concerning the safety of operating workers. In response to the above problems, a high-altitude saw that is convenient for workers to trim high-altitude branches on the ground has appeared on the market. A small electric saw is installed on the end of a long pole, and the other end of the long pole is held in hand to extend the electric saw. Just trim where you trim. [0003] However, the long pole part of the existing high-altitude saws on the market generally cannot be adjusted to a suitable length according to the needs, and it is...

Problems solved by technology

[0003] However, the long pole part of the existing high-altitude saws on the market generally cannot be adjusted to a suitable length according to the needs, and it is inconvenient to use; some height-adjustable high-altitude saws are inconvenient to adjust the length of the long pole. The relative movement between them is relatively blocked. After the length is adjusted, it is also inconvenient to fix the telescopic rod, which is not convenient for the use of high-altitude saws.
