Meanwhile the first gear being fixedly connected on the second motor output shaft is rotated, and during first gear rotation, with
The second gear of first gear engagement rotates with it, and drives and rotated with the shaft that second gear is fixedly linked, and shaft turns
During dynamic, the second clamping jaw is rotated with it, and end of second clamping jaw far from hinge joint is rotated towards the first clamping jaw side.
Preferably, second clamping jaw place opposite with the first clamping jaw is provided with the through-hole passed through for the first clamping jaw.
Through the above technical solutions, being clamped using the first clamping jaw and the second clamping jaw to the lesser branch of width
When, the first clamping jaw can be passed through from the through-hole on the second clamping jaw, with the opposite side wall of the first clamping jaw of guarantee and the second clamping jaw
It can be abutted against with the lateral wall of branch, and the lesser branch of width is clamped.
Preferably, first clamping jaw is provided with infrared transmitter, second clamping jaw on the side wall of the second clamping jaw
Place opposite with infrared transmitter is provided with infrared remote receiver, is provided on the holding rod for being electrically connected with infrared remote receiver
Signal processor, and signal processor is electrically connected with the second motor and is used to control the opening and closing of the second motor.
Through the above technical solutions, the end of control holding rod carry out it is mobile so that branch be moved to the first clamping jaw and
When between the second clamping jaw, when branch blocks the infrared ray that infrared transmitter on the first clamping jaw emits, so that being located at the second clamping jaw
On infrared remote receiver can not receive infrared signal, it is infrared at this time connect receiver to signal processing apparatus send electric signal,
Signal processing apparatus handles electric signal later, and sends electric signal to the second motor, so that the second motor is opened and controlled
It is close to each other to make the end of the first clamping jaw and the second clamping jaw far from hinge joint.The tree trimming equipment being arranged in this way, does not need
