The wall portion of body 51, the central end that slide calliper rule reset clockwork spring 52 is connected to slide calliper rule reset winder 54, and it is inclined that slide calliper rule reset winder 54
The end for resetting clockwork spring 52 from slide calliper rule is provided with slide calliper rule fixed thereto and resets runner 55, and slide calliper rule reset is wound with one on runner 55
End drive belt 56 fixed thereto, the suspension end of drive belt 56 is connected with driving rack 41, and is also equipped with lower house 10
For the row's chi guide wheel 53 for guiding drive belt 56 to flex outward, the drive belt 56 guided by arranging chi guide wheel 53 is horizontal cloth
Put and be connected with driving rack 41;When first clamping bar 21 is away from the second clamping bar 22, the driving rack being connected with the first clamping bar 21
41 along its length away from the first clamping bar 21, and driving rack 41 drives connected drive belt 56 along the length of driving rack 41
Direction is stretched, and runner 55 is around own axis and drives slide calliper rule for the reset of driving slide calliper rule in the suspension end moving process of drive belt 56
Reset winder 54 to rotate, slide calliper rule, which reset, drives connected slide calliper rule to reset clockwork spring 52 around slide calliper rule in the rotation process of winder 54
Reset winder 54 axis be wound in slide calliper rule reset winder 54, after being measured, reel spring gear 341 drive around
The take-up of spool 321 and make driven locating part 43 along the axis of the first screw mandrel 64 to close to the one end of the second helical gear 42 move when, from
The constraint of 43 pairs of active locating parts 44 of dynamic locating part is withdrawn, and now slide calliper rule reset the driving slide calliper rule of clockwork spring 52 and reset winder 54 around certainly
Body axis is rotated, and slide calliper rule reset the driving slide calliper rule of winder 54 and reset runner 55 around own axis, and slide calliper rule reset 55 turns of runner
Drive belt 56 is set to reset the winding of the circumference of runner 55 and by the driving row's chi guide wheel 53 of drive belt 56 around itself around slide calliper rule during dynamic
Axis is rotated, and pulls driving rack 41 to be transported along rail axis to one end close to the second clamping bar 22 by the tractive force of drive belt 56
Move, and complete the first clamping bar 21 and reset.
It is more highly preferred to, the first clamping bar 21 is vertical with the axis of epivalve length direction close to the side of the second clamping bar 22,
Second clamping bar 22 is vertical with the axis of epivalve length direction close to the side of the first clamping bar 21;It ensure that using the layout type
First clamping bar 21 and the second clamping bar 22 survey nursery stock diameter error minimum when clamping nursery stock, while preventing clamping device 30
Tilt, it is ensured that straight line where the contact point of clamping process the first clamping bar 21 and the second clamping bar 22 is total to plane where nursery stock diameter
Face.
More perfect, epivalve length direction is provided with graduation mark;Graduation mark is set to make to apply in epivalve length direction
Man-hour can be recorded to nursery stock diameter, be easy to after excavating to excavating nursery stock size be classified according to the diameter of nursery stock.
