Abstract

The invention discloses a pair of high-altitude pneumatic pruning shears which includes a pair of wheel type shears, a pull-back spring, a cylinder, a reinforcing plate, a connector, a fixing plate, atelescopic rod and a bluetooth switch module. A handle of the pair of wheel type shears is a rotating handle and is matched with the connector through a groove and a wheel, the other handle is fixedto the fixing plate, the connector is mounted on a push rod of the cylinder, the push rod is provided with the pull-back spring, one end of the cylinder is fixed to the fixing plate, the other end ofthe cylinder is fixed to the reinforcing plate, the reinforcing plate is connected with the fixing plate, and the top of the telescopic rod is fixed to the reinforcing plate. A solenoid valve switch is controlled to be switched on or switched off through the bluetooth switch module to control extending stroke of the cylinder. The pair of high-altitude pneumatic pruning shears has the advantages that the pair of high-altitude pneumatic pruning shears is simple in structure, light and reasonable, a cutter is durable, and the pair of high-altitude pneumatic pruning shears has a large operation range and is high in production efficiency and low in labor intensity.

Description

[0001] This application is a divisional application with application number 2017105052491, an application date of June 28, 2017, and the title of the invention "High-altitude pneumatic pruning shears based on Bluetooth technology". technical field [0002] The invention relates to a high-air pneumatic pruning shear. Background technique [0003] At present, there are various forms such as hand-held backpack type, vehicle-mounted type and automatic type to the machinery of tree pruning and pruning both at home and abroad. Among them, the main tool is the hand-held knapsack pruning machine, and there are two types of hand-held knapsack with or without power and power. The supporting power of the powered pruning machine has external power such as pneumatic, hydraulic transmission, electric, small gasoline engine and small diesel engine. The vehicle-mounted pruning machine is equipped with a hydraulic folding arm on the tractor. The end of the folding arm is equipped with a hyd...
