[0027] Working principle:
[0028] In the measurement of bamboo diameter, first remove the handle sleeve 15 on the mounting plate 1 and take out the clamp plate 5 from the storage cavity 13. If the bamboo diameter is large, the spare clamp plate 14 can be taken out and connected to the clamp plate 5. Then insert the clamp plate 5 on the connecting block 4 and the T-shaped slider 7. Then re-sleeve the handle sleeve 15 on the mounting plate 1 to block the storage cavity 13. Manually pull the clamp plate 5 on the T-shaped slider 7 to make the T-shaped slider 7 away from the connecting block 4. During this process, the tension spring 10 is stretched to generate elastic force. The two clamp plates 5 on the connecting block 4 and the T-shaped slider 7 are sleeved on the bamboo at the appropriate position. Then hold the handle sleeve 15 and rotate the mounting plate 1. During this process, the T-shaped slider 7 will change its position with the change of the bamboo thickness and shape. The displacement change of the T-shaped slider 7 will draw lines on the drawing paper 3 through the support 11 and the line pen 12. After the measurement is completed, observe the drawing lines on the drawing paper 3. The value corresponding to the center point of the line on the scale line 2 on the drawing paper 3 is the specific value of the bamboo diameter. The principle is that the value of the end of the line on the drawing paper 3 closest to the connecting block 4 on the scale line 2 represents the thinnest part of the bamboo cross section. Conversely, the value of the end away from the connecting block 4 on the scale line 2 represents the thickest part of the bamboo cross section. Taking the average value is the bamboo diameter. Thus, the value corresponding to the center point of the line on the scale line 2 on the drawing paper 3 is the bamboo diameter.
