The quick rotation of turn disk 114.
Additionally, due to being provided with cursor 115 on turntable 114, so when turntable 114 rotates, cursor 115
Can be with movement, but cursor 115 follows the movement but can be different because of the speed speed of the starting moment of turntable 114.
When 114 moment of turntable starts quick rotation, and cursor 115 is due to inertia, can make cursor 115 to
The opposite direction rotation of 114 rotation direction of turntable, at this moment, the clamping joint 116 positioned at 115 one end of cursor can exceed turntable 114
Boundary stop the rotation of cursor 115 to interfere with block 119, and cursor 115 will receive turntable 114 simultaneously
The blocking of upper limit position block 118 thereby realizes the rotation by stopping cursor 115 to stop turntable 114, turntable 114
It drives runner 112 to stop, increasing the frictional force with band 103, prevent band 103 from continuing to slide, avoid band 103 from pressure head
It is skidded off between 106 and pedestal 101.
And when 114 slow start of turntable rotation when, since cursor 115 is smaller by inertia effects at this time, substantially with
Turntable 114 rotates simultaneously, will not generate biggish speed difference, so the clamping joint 116 of cursor 115 is without departing from turntable 114
Boundary, and then the interference of clamping joint 116 and block 119 will not occur, turntable 114 can be with smooth rotation, and runner 112 can also
To continue to rotate, the frictional force of runner 112 Yu band 103 not will increase, band 103 can continue to slide, can be smoothly by hoop
Band 103 is extracted out between pressure head 106 and pedestal 101, and the present invention is removed from trees.
The present embodiment uses the setting of this structure, enables to prevent band 103 when 103 quick sliding of band
Movement, and band 103 is not prevented then to move when band 103 slides at a slow speed.Because when 103 quick sliding of band
It waits, mostly band 103 is pulled by biggish external force suddenly, and this external force itself is not the tension that arboreal growth generates, more
Destruction for external force to equipment, cable or adjustable clip, band 103 cannot continue sliding and just them be avoided to break equipment
It is bad;And when trees normal growth, be to the tension extended out that band 103 and garter spring 102 generate it is slowly, this
When due to the angular momentum of cursor 115 it is smaller, just not will cause the rotation discrepancy of cursor 115 and turntable 114 so that turn
Swing arm 115 is basic and turntable 114 rotates simultaneously, the interference of clamping joint 116 and block 119 is avoided, so that 103 energy of band
Enough normal slidings.
When runner 112 stops operating, turntable 114 also stops operating, at this time under the action of tension spring 117, so that
Cursor 115 resets, and then clamping joint 116 is withdrawn, so that clamping joint 116 is located in the boundary of the turntable 114, does not influence
The rotation again of turntable 114.
