Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Example 1
This embodiment provides a pneumatic pruning scissors in high altitude based on bluetooth, includes: the device comprises wheel type scissors, a pull-back spring, a cylinder, a reinforcing plate, a connector, a fixing plate, a telescopic rod and a Bluetooth switch module; a handle of the wheel type scissors is a rotating handle, the rotating handle is matched with the connector through a groove and a wheel, the other handle is fixed on the fixing plate, the connector is installed on a push rod of the air cylinder, a pull-back spring is arranged on the push rod, one end of the air cylinder is fixed on the fixing plate, the other end of the air cylinder is fixed on the reinforcing plate, the reinforcing plate is connected with the fixing plate, and the top of the telescopic rod is fixed on the reinforcing plate; the push stroke of the cylinder is further controlled by controlling the on-off of the electromagnetic valve switch through the Bluetooth switch module.
Example 2
As a further limitation on embodiment 1, the connecting head includes: the device comprises a shaft a, a shaft b, a rod end bearing, a thin-wall bearing a, a thin-wall bearing b, a flange shaft sleeve, a distance adjusting sheet a, a distance adjusting sheet b and a bearing sleeve; the shaft a penetrates through the distance adjusting sheets a and b, the thin-wall bearing a is fixed at the end part of the shaft a, and the bearing sleeve is sleeved on the outer periphery of the thin-wall bearing a; the shaft b sequentially penetrates through the flange shaft sleeve, the distance adjusting sheet a, the rod end bearing and the distance adjusting sheet b, and the thin-wall bearing b is fixed at the end part of the shaft b.
The pruning shears adopt a telescopic rod to be manually adjusted to enable the shears to be partially adjusted to the height desired by an operator, then the pushing distance of a single-action cylinder is controlled by changing the on-off of a solenoid valve switch (type 3V 210-08, and an air inlet and an air outlet are reversely connected) through manually controlling a Bluetooth switch module, the single-action cylinder is a basic element in the cylinder, the single-action cylinder only has one-direction movement and is driven by air pressure, and the resetting is driven by spring force or dead weight or other external forces. The power is transmitted to the rotating handle of the scissors through the connector, and the pruning of the branches is realized.
