Shape be adapted, the upper end of guide shaft 362 is equipped with the limit annulus of protrusion, and the external socket of guide shaft 362 pushes guide shaft 362
The contrary wind spring 366 that cavity direction moves in towards wind gathering cover 310；More perfectly, inverse to improve the precision incuded and shortening
The stroke of wind spring 366, against the upper surface for answering aerofoil 364, the other end of contrary wind spring 366 supports for one end of contrary wind spring 366
To the inner cavity of sleeve 340.
When 300 low-speed motion of windage induction mechanism or when being moved within the scope of safe speed, gather in wind gathering cover 310
Air is from answering between aerofoil 364 and wind gathering cover 310 interval to flow to air-permeating hole 330, and by air-permeating hole 330 from wind gathering cover 310
It flows out upper end；When 300 high-speed motion of windage induction mechanism or when being higher by safe speed range, relatively strong winds in wind gathering cover 310
Resistance, the resistance that the air push gathered in wind gathering cover at this time answers aerofoil 364 to overcome contrary wind spring 366 move upwards, and answer aerofoil 364
It is bonded with 310 inner wall of wind gathering cover when moving upwards, so that air-permeating hole 330 and 310 inner cavity of wind gathering cover completely cut off, wind gathering cover at this time
Air drag in 310 further increases.
As shown in Fig. 1,8-10, be provided on shell 200 positioned at 220 liang of end sides of guide rail guide groove and with guide rail guide groove 220
The wedge groove 240 being connected is matched with wedge lock block 600 in wedge groove 240 and wedge groove 240 can be oriented to wedge-shaped latch segment
600 towards guide rail guide groove movement, is provided with guide post 610 on wedge lock block 600, is provided on shell 200 and 610 phase of guide post
Match and is oriented to the first sliding groove 230 of the wedge-shaped latch segment 600 towards guide rail guide groove movement；More optimally, it is reduction wedge groove
The damage of 240 frictional force and reducing mechanism generated during being oriented to wedge-shaped latch segment 600, on the inclined-plane of wedge groove 240
It is provided with several uniform intervals and along the roller bearing slot 250 of 240 chamfer length direction array distribution of wedge groove, roller bearing slot 250
Inside being equipped with can be around the roller bearing of own axis, to reduce the frictional force that wedge lock block generates in sliding process；For
Braking effect is improved, wedge lock block 600 is generated towards reticulate pattern is provided on the braking end face of guide rail guide groove 220 using reticulate pattern
Frictional force shorten braking distance.
As shown in figures 2-6, the wall portion of wind gathering cover 310 is connected with cantilever 320, and the other end of cantilever 320 is connected to driver
