Conveying line device with function of retaining workpieces temporarily

The utility model discloses a conveying line device with a function of retaining workpieces temporarily. A tradition structure with friction strips and friction furrow wheels is abandoned and replaced by an annular friction disc and an idle gear meshed with a chain. A round turning disc is disposed at one end of a drive shaft of a frame to enable the conveying line device to be more reliable and smooth in turning. Profiling blocks matched with pins disposed on the turning disc are disposed on two sides of a support frame. Turning of the support frame is realized by inserting pins into turning holes on the profiling blocks. The conveying line device with the function of retaining workpieces temporarily is simple in structure, ingenious in design, and reasonable in layout. A damping (spring) structure is used for driving the support frame to move, the pins and turning holes are used for driving the support frame to turn, and accordingly moving is more reliable, and operation complexity caused by frequent replacing of friction strips can be avoided.
