[0007] As a further specific optimization of the technical solution of the present utility model: the crank 4 is connected to the main transmission shaft 1 through a flat key.

[0008] As a further specific optimization of the technical solution of the present utility model: a main transmission shaft limit block 7 is provided at one end of the main transmission shaft 1 .

[0009] As a further specific optimization of the technical solution of the present invention: a rotating shaft positioning baffle 3 is provided on the connecting end surface of the rotating shaft 5 and the lower end hole of the crank 4, and is fastened to the rotating shaft 5 by bolts.

[0010] As a further specific optimization of the technical solution of the present invention: a rotating shaft limiting baffle 10 is provided on the end face of the rotating shaft 5 and is fastened with bolts.

[0011] As a further specific optimization of the technical solution of the present invention: the fisheye joint 8 is externally connected to a bearing mechanism, and the bearing mechanism is combined with a linear guide rail. The reduction motor is driven by the main transmission shaft 1 to transmit the torque to the adapter block 6, thereby driving the bearing mechanism on the fisheye joint 8 to perform lifting movements.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] When the mechanism is driven, the main shaft transmits torque to the crank, which is movably connected to the adapter block through the shaft. The torque is then transmitted to the adapter block, which then cooperates with the linear guide rail accessories to move the adapter block up and down, meeting the requirements of production activities. This utility model has an ingenious structural design, large load-bearing capacity, wear resistance, durability, and high strength. BRIEF DESCRIPTION OF THE DRAWINGS
