Wiping power can prevent the inertia of rotating shaft 10 from rotating.Such as shown in Fig. 2, when driven pulley 40 by driving wheel drive rotate when, rotating shaft 10 with
Driven pulley 40 rotates, and frictional force of the rotating shaft 10 between friction component 31 will rotate together with drive friction component 31, but rub
Component 31, upon rotating, will stretch above-mentioned extension spring 321, extension spring 321 is produced deformation and form a pulling force, work as pulling force with rotating shaft 10
When equal with frictional force, friction component 31 will keep balancing, and no longer be rotated with rotating shaft 10.It is driven when driving wheel stops operating
Wheel 40 slowly stops because inertia will be rotated further a low-angle, and now rotating shaft 10 will also stop operating, with friction group
There is no relative motion between part 31, just there is no frictional force yet, now friction component 31 will pull the side of doing by the pulling force of extension spring 321
To rotation, home position is returned to.Rotating backward for friction component 31 will produce a reverse friction power again between rotating shaft 10, drive
The counter motion of rotating shaft 10, so as to prevent the inertia of driven pulley 40 to rotate, driven pulley 40 is withdrawn into the state that strainer tightens.From
And strainer is in tensioned state all the time, to ensure that the point of particulate matter enrichment can be transferred to the position of test point exactly, have
Effect improves accuracy of detection.
