The utility model discloses a cylinder material is grabbed and is held conveyor with second grade propelling movement function, including left jack catch, push mechanism base, jack catch mount pad, right jack catch, a left side open and shut half gear, the right side open and shut half gear and drive half gear, install chain push mechanism, time delay axle mechanism, electronic jar push mechanism and control box on the push mechanism base, jack catch mount pad and push mechanism base pass through hexagon socket head cap screw fixed connection, jack catch mount pad both sides are articulated with left jack catch axle and right jack catch axle respectively. This cylinder material is grabbed and is held conveyor with second grade propelling movement function uses chain drive as the pusher of the first order, can realize long distance propelling movement, tentatively send the bar into the target machine promptly in to the chain is in the change of sprocket department camber, can make push away that the hook is automatic and take in the apparatus in, does not influence grabbing of material and hold, the last compactness of implementation structure arranges, can with the material to more depths propelling movement of target machine, realize the transport task that snatchs of different diameter bars.
