The speed turn handle 9 can make the first motor rotate, thereby driving the rotating shaft 3 and the moving wheel 4 to rotate, and then driving the trolley to move without manual pushing, thereby reducing the workload; a slide groove 5 is provided on the upper surface of the cross bar 2, and a lifting limit mechanism 6 is symmetrically slidably connected inside the slide groove 5, and a driving mechanism 7 that cooperates with the lifting limit mechanism 6 is installed inside the slide groove 5, and an operating panel 10 that cooperates with the lifting limit mechanism 6 and the driving mechanism 7 is fixedly installed at the center position of the outer surface of the armrest 8.

[0021] In this embodiment, the lifting and limiting mechanism 6 includes a rectangular tube 61 slidably connected to the inside of the slide groove 5, and a second motor 62 is fixedly installed on the inner bottom of the rectangular tube 61. The output shaft of the second motor 62 is fixedly connected to a one-way screw rod 63, and the outer surface of the one-way screw rod 63 is threadedly connected to a lift rod 64 that is slidably connected to the inside of the rectangular tube 61.

[0022] In this embodiment, a slope 65 is provided on one side of the top end of the push rod 64 to facilitate insertion into the bottom of the channel steel, thereby facilitating lifting the channel steel.

[0023] In this embodiment, the driving mechanism 7 includes a bidirectional screw rod 71 rotatably connected to the inside of the slide groove 5, both ends of the bidirectional screw rod 71 pass through the bottom of the corresponding rectangular tube 61, and the bidirectional screw rod 71 is connected to the internal thread of the rectangular tube 61, and the two rectangular tubes 61 are symmetrically arranged on both sides of the bidirectional screw rod 71.
