Specific embodiment
The utility model is elaborated below in conjunction with attached drawing.
A kind of telescopic electric shears for pruning upper branch as shown in Figure 1 to Figure 2, including power supply 8, control section, power section, work
Make part, protective device and handle 16.The power supply 8 is simultaneously control section, power section and working portion are powered, the control
System part mainly includes single-chip microcontroller 9 and button 11, and the single-chip microcontroller 9 is connect with power supply 8 and power section respectively, and main control is just
Rotating forward, reversion and the stopping of direct current generator 10 are inverted, the button 11 is connect with power supply, power section, working portion, described to press
Button 11 has 3, and effect is on-off, the elongation of telescopic rod 6 and the retraction of telescopic rod 6 for controlling 2 circuit of electromagnet respectively.
The power section is positive and negative rotation direct current generator 10, by the offer electric power of power supply 8 and the control by single-chip microcontroller 9.The work department
Divide and be mainly made of telescopic rod 6, electromagnet 2, spring 4, rhombus expansion brackets 3 and scissors bit 1, the telescopic rod 6 is being driven by electricity
It can be realized by the transmission effect of rack-and-pinion down and at the uniform velocity be stretched, the electromagnet 2 is fixed in rhombus expansion brackets 3 and by exhausted
