It is scheduled at lateral supporting leg outlet 1301, to rub to lateral supporting leg 1, removes the dust that 1 surface of lateral supporting leg retains, keep away
Exempt from dust to enter as lateral supporting leg 1 recycles inside lateral supporting leg housing 201, then by the connector of 1001 one end of nylon drag chain block
Carrier bar 1002 and the undertaking carrier bar 1003 of another 1001 one end of nylon drag chain block are attached, and are dragged to be spliced into a nylon
Then second high-pressure hose 9 is inserted into nylon drag chain, the second high-pressure hose 9 is fixed by fixed ring 1006, keeps away by chain
Exempt from the second high-pressure hose 9 to move back and forth；
Then it drives the first seamless steel pipe 7 mobile by lateral supporting leg 1, then drives the second high-pressure hose 9 mobile, so that
Oil path block 8 is moved to 9 bending part of the second high-pressure hose, thus increase the length of pipeline, when the recycling of lateral supporting leg 1,
So that oil path block 8 is moved on the contrary to 9 bending part of the second high-pressure hose, so as to shorten the length of oil pipe, can effectively avoid
The shock of outer bound pair oil pipe scratches, while making it in seal chamber body activity, when can effectively extend the ageing failure of rubber oil hose
Between, and the aesthetics of vehicle overall appearance is improved, extend the service life of oil pipe, save the cost passes through the work of oil path block 8
With being easy to implement 9 deflecting of the second high-pressure hose, avoid the second high-pressure hose 9 from rupturing in deflecting, when the second high-pressure hose
In 9 drawing process, according to the diameter adjustment adjustment axis 1202 of the second seamless steel pipe 11, to adjust the height of limit nylon wheel 1205
Then degree limits the second high-pressure hose 9 by limiting nylon wheel 1205, avoids the second high-pressure hose 9 in the course of work
