The operator places the objects to be transported on the transport bracket 41, and transports the objects to be transported to the fixed bracket 42 through the transport bracket 41, so that the subsequent machinery can pick up the materials from the fixed bracket 42.

[0035] The installation frame 1 is located between the manual placement operation area and the mechanical picking operation area, and is preferably a cubic frame, which is formed by staggered connection of horizontal bars and vertical bars, and a support leg is arranged at the bottom.

[0036] The sliding driving member 23 and the lifting driving member 31 are both driving cylinders.
