Problems solved by technology

At present, the transmission rod of high-branch chainsaw is divided into two types: fixed type and rotary telescopic type. The length of the fixed type transmission rod is fixed. Although the length can be extended by adding an extension rod, it is inconvenient to operate and use; although the rotary telescopic type can adjust the length, but The operation is inconvenient and the transmission stability is poor. The transmission components are generally steel shafts or aluminum alloy shafts. The steel shafts are heavy and the aluminum alloy shafts are weak. Under this feature, the two materials cannot take into account the length under this structure. and strength requirements
One of the main performance indicators of high-branch chainsaws is the length. The larger the adjustable range of the length, the better, and the longer the maximum stretching length, the better. However, the longer the length, the greater the weight, and the weaker the strength. The increase in weight will increase the labor intensity. Affect the user experience, weakening the strength will affect the life of the machine and increase the failure rate of the machine

Embodiment Construction

[0009] Such as figure 1 As shown, a telescopic high-branch saw transmission rod combination includes a front transmission shaft 1, a front sleeve 2, a manual locking device 3, a front connection sleeve 4, an intermediate sleeve 5, an intermediate transmission shaft 6, and a rear connection sleeve 7 , rear transmission shaft 8, rear casing 9, connecting shaft 10.

[0010] The specific embodiment of the present invention is: the front transmission shaft 1 and the front casing 2 are axially fixed, the front casing 2 is connected with the middle casing 5 through the front connecting sleeve 4, and the front connecting sleeve 4 is provided with a manual locking device 3. When the locking device 3 is loosened, the front sleeve 2 can slide into the middle sleeve 5. When the manual locking device 3 is tightened, the positions of the front sleeve 2 and the middle sleeve 5 are fixed and cannot move relative to each other; the middle sleeve 5 The position is fixed with the intermediate t...

Abstract

The invention discloses a telescopic high-branch saw transmission rod combination, which comprises a casing pipe combination and a transmission shaft combination, wherein the casing pipe combination contains a front casing pipe, a front connecting sleeve, a middle casing pipe, a rear casing pipe and a rear connecting sleeve; the transmission shaft combination contains a front transmission shaft, a middle transmission shaft, a connecting shaft and a rear transmission shaft; the transmission shaft combination is installed in the casing pipe combination; the casing pipe combination supports and spaces the transmission shaft combination; the front casing pipe and the middle casing pipe can relatively slide along the axial direction; the position of the middle casing pipe and the position of the rear casing pipe are fixed; the front transmission shaft and the middle transmission shaft can relatively slide along the axial direction; and the position of the rear transmission shaft and the position of the middle transmission shaft are fixed. The telescopic high-branch saw transmission rod combination has the beneficial effects that the telescopic high-branch saw transmission rod combination has a simple structure, is easy in operation, is convenient in storage, can meet the strength requirement of the transmission shaft and avoids excessive weight, and meanwhile, the extending length of the transmission rod is guaranteed to be as long as possible.

Description

technical field [0001] The invention relates to the technical field of garden machinery, in particular to a telescopic combination of high-branch saw transmission rods. Background technique [0002] High-branch saws are an important tool for trimming branches of economic trees and green forests with high crowns. There are many types of high-branch saws. According to different powers, they can be divided into electric high-branch saws and high-branch chainsaws. Among them, gasoline-powered high-branch chainsaws are the most used. widely. At present, the transmission rod of high-branch chainsaw is divided into two types: fixed type and rotary telescopic type. The length of the fixed type transmission rod is fixed. Although the length can be extended by adding an extension rod, it is inconvenient to operate and use; although the rotary telescopic type can adjust the length, but The operation is inconvenient and the transmission stability is poor. The transmission components ar...
