In some alternative embodiments of the present application, the handle 101 is provided with a switch 111, and the switch 111 is electrically connected to the controller 420 and the lifting mechanism 600, respectively. The switch 111 can realize the simple and convenient control of various movement modes of the frame 200, such as forward, backward, acceleration, deceleration, lifting or lowering, and the like. The number of the switch elements 111 may be plural, for example, 5, 6, 7, etc., and the specific number of the switch elements 111 may not be limited in the embodiment of the present application.

In some alternative embodiments of the present application, the switch member 111 includes at least one of a start switch, a rise switch, a fall switch, a protection switch, and a horn switch. The handle 101 may be provided with 1, 2, or 3 of the above start switch, the ascending switch, the descending switch, the protection switch, and the horn switch, or may be provided with all the above switches, so as to enrich the control functions of the switch member 111 of the handle 101.

For example, in the embodiment of the present application, the protection switch may also be referred to as an anti-collision reverse switch, where the protection switch is triggered when the protection switch collides with a human body, and the controller 420 further controls the tractor to move reversely, so as to avoid collision injury to the human body, so that both the human body and the goods have better safety.

Optionally, the tractor further includes a trigger 430, wherein the trigger 430 is connected to the handle connector 110 near the connecting rod 120 and is electrically connected to the controller 420; based on the pressing of the trigger 430 by the connecting rod 120, the controller 420 controls the tractor to move. For example, in case that the inclination angle between the connection rod 120 and the horizontal plane is a preset angle range, the connection rod 120 presses the trigger 430 so that the controller 420 of the tractor controls the frame 200 to perform normal movement. When the inclination angle between the connecting rod 120 and the horizontal plane is out of the preset angle range, the connecting rod 120 does not press the trigger piece 430, and the controller 420 controls the brake disc 402 to lock the driving motor 405 and the driving wheel 404, so that the tractor cannot move, and a slide slope is prevented.

For example, the preset angle range may be 30-60 °, or 35-70 °, or 25-75 °, or the like, and may be set according to actual needs, the extension length of the trigger 430, or the like, which in the embodiment of the present application may not be limited.

Optionally, the frame 200 further includes a power supply 290 and a display 291, wherein the power supply 290 is electrically connected to the controller 420 and the lifting mechanism 600, and the display 291 is electrically connected to the power supply 290. Thus, a stable and reliable power source can be provided for the controller 420 and the lifting mechanism 600 through the power supply 290, and the electric quantity of the power supply 290 can be observed in real time through the display screen 291, so that the power supply 290 can be replaced or charged in time when the electric quantity is low.

For example, in the embodiment of the present application, the power supply 290 may be a quick-change lithium battery, and the quick-change lithium battery may be plugged onto the connection frame 250 of the frame 200, so as to facilitate replacement. In addition, the power source 290 may be a battery of other types, the power source 290 may be connected to other positions of the frame 200, etc., and the specific type and arrangement position of the power source 290 in the embodiment of the present application may not be limited.
