The use of parallel fixed joints is common. Sometimes the leg of
the aluminum tube workbench can not bear weight well by relying on
one aluminum tube alone. At this time, the number of aluminum tubes
can be increased by using this joint, so as to improve the bearing
capacity of the workbench. Only one pair of screw and nut can
easily fix two aluminum tubes. Aluminum items can be widely used in
household, automobile, electronics, chemical industry, commercial
logistics, flexible storage equipment, pharmacy, machine
manufacturing.
