Problems solved by technology

The commonly used tool for pruning branches is "high branch saw" (commonly known as "chain saw"), which is connected by the saw head and the operating rod. Since the operating rod is made of metal, when it is close to the live wire, it is easy to cause the operator to get an electric shock. , when carrying out tree branch pruning operations, power outages must be carried out on the line, which has brought inconvenience and losses to electricity customers; , the chain saw is difficult to start, and it is difficult to work normally; moreover, the saw head of the chain saw is single, and only one kind of saw head can be provided, which is sometimes not suitable for the tool

Embodiment 1

[0031] Embodiment 1. An electric high-branch saw used for live work

[0032] figure 1 , figure 2 The shape and structure of the high-branch saw as a whole and its parts disassembled are shown, respectively.

[0033] The rechargeable detachable power supply 1 is a lithium battery, and the power supply 1 is electrically connected to the power supply base 2; a small motor is arranged in the power supply base 2, which converts electric energy into kinetic energy for motor rotation.

[0034] The power supply base 2 is connected to the tail of the gear box 3; the operating rod fixing part 4 is installed on the upper end of the gear box 3, and the handle 5 is connected to the operating rod fixing part 4. A handle bolt 6 passes through the connection hole between the handle 5 and the operating rod fixing part 4 , connecting the handle 5 and the operating rod fixing part 4 as a whole;

[0035] The transmission shaft 8 is placed inside the insulating operating rod 7 (the insulating ...

Abstract

The invention relates to a live working electric lopper saw which mainly comprises a gearbox, an operating rod fixing part, a handle, an insulating operating rod, a transmission shaft and a saw head.The electric lopper saw converts electric energy into kinetic energy to drive a gear in the gearbox to rotate, so that the transmission shaft drives the saw head to operate, and namely, the transmission shaft drives a guide plate saw head to vertically move or drives a disc saw head to rotate, so that tree branches are cut. The lopper saw can trim tree branches beside live conductors lower than 20kilovolts and install different saw heads according to different tree varieties, growing conditions and environments of the tree branches and the like, and the lopper saw has the advantages that thesaw is safe, reliable and wide in application range, noise and air pollution are reduced and the like.

Description

technical field [0001] The invention relates to a tool for live work, in particular to an electric saw used for trimming branches near high-altitude live wires. Background technique [0002] When the power conductor passes through trees and jungle areas, it is easy to cause short-circuit faults due to the close proximity of tree branches to the conductor, causing power outages and other accidents. For this reason, it is necessary to trim the branches near the power line. The commonly used tool for pruning branches is "high branch saw" (commonly known as "chain saw"), which is connected by the saw head and the operating rod. Since the operating rod is made of metal, when it is close to the live wire, it is easy to cause the operator to get an electric shock. , when carrying out tree branch pruning operations, power outages must be carried out on the line, which has brought inconvenience and losses to electricity customers; , the chain saw is difficult to start, and it is di...
