Claims

[Scope of utility model registration request]

When the start button 5 is pressed, the power relay 20 shifts to close the circuit, and the motor 1 is connected via the polarity switching relay 25.
By applying an excitation voltage 35 with a normal polarity to 0, the shaft 7
A structure in which a decelerator 6 equipped with a blade 8 supported by the decelerator 6 is rotated in the forward direction to a position 9 where cutting of branches, etc. is completed;
At the above position 9, the push pin 12 comes to the position 14, the reverse switch 15 is closed, the coil 26 is energized, the polarity reversal relay 25 is reversed, and the excitation voltage 35 of the polarity for reversing is applied to the motor 10. Due to the structure that reversely rotates the decelerator 6 and the above-mentioned reverse rotation, the push pin 1
2 closes the forward rotation switch 13, energizes the coil 26 to shift the polarity reversing relay 25, and also energizes the coil 21 to shift the power relay 20 and open the battery 18. .
