Figure, Fig. 2 combination Fig. 3 analysis is it is found that the dust cap 200 of the utility model includes plane cover 220 and strip connected to it
Fixing card 210, which extends vertically along the side of plane cover 220 is uniformly distributed, at least containing symmetrical two long
Strip fixing card 210.
Further, fixing card 210 is set to the inside of the outer of plane cover 220, and fixing card 210 is in plane cover 220
Frontal plane of projection composition annulus outer diameter be equal to connecting tube internal diameter, in other words, the circle formed on the outside of fixing card 210 it is straight
Diameter is equal to the internal diameter of connecting tube, and fixing card 210 can be inserted in connecting tube.Particularly, outside fixing card 210 and plane cover 220
Limit is played the role of at the position reserved between, has both prevented in 200 company's of being fully inserted into machine pipe of dust cap, bad taking-up, and can
So that plane cover 220 covers the end of Lian Jiguan completely, prevent dust from entering Lian Jiguan.
In some embodiments, each fixing card 210 includes the straight portion connecting with plane cover 220 and longitudinally prolongs along straight portion
Even machine is inserted into dust cap 200 due to the presence of bending section to the center curvature of plane cover 220 in the bending section stretched, bending section
