Being used in conjunction with each other for structure be, thus use when can the more preferable device it is each it is hard-packed be united, from
And avoid to collapse when in use and hold damage, so it follows that the device is safer.
When in use, when needing to overhaul, together slowly by the structures such as interior left axle bearing sleeve 401 and interior right axle bearing sleeve 405
Back-out come, screw threads for fastening circle 412 is back-outed again from thereon then, is then dismantled and is overhauled, then outer bearing sleeve 407
Slowly back-out from bearing block sole piece 1 with clamp clip 408, then back-outs by clamp clip 408 again, so maintenance is facilitated,
So as to which preferably it is separately overhauled with each structure.
It can to sum up obtain, the supporting axle of the easy access holds seat, passes through interior left axle bearing sleeve 401, linking thin plate 403, inner ring spiral shell
Groove 404, outer bearing sleeve 407, clamp clip 408, short screw 411 and screw threads for fastening circle 412 is isostructural is used in conjunction with each other, because
Most connection type for above structure is all the connection types such as threaded connection, clamping mostly, so being dismantled
When it is more convenient, so the convenient inspection to it of operator, also facilitate maintenance, and because of having clamp clip 408, internal screw thread circle
402 and external screw thread cylinder 406 is isostructural is used in conjunction with each other, so can preferably be installed when in use, and
The normal use of the device is not interfered, so by above structure it is found that the device passes through screw with inspection and maintenance is facilitated yet
7, anti-Le piece 6, channel 5, screw rod 2, bearing block sole piece 1 and screw thread circular groove 409 is isostructural is used in conjunction with each other, so using
When can be preferably stronger in combination by the device, institute to avoid occurring situations such as dangerous when in use, so
It can be seen from the above, the device is more practical when in use, durable and conveniently, passes through screw 7, short screw 411 and screw rod 2 etc. and tie
Being used in conjunction with each other for structure be, thus use when can the more preferable device it is each it is hard-packed be united, from
And avoid to collapse when in use and hold damage, so it follows that the device is safer.
