Multiple guide grooves 202 are formed inside the frame 1, and guide blocks 203 are inserted into each guide groove 202. The outer sides of the multiple guide blocks 203 are connected to the plug-in blocks 2 on the adjacent side. A push arm 204 is provided on one side of the plug-in block 2. The two ends of the push arm 204 are connected to the guide block 203 and the electric push rod 205 respectively by pins. The side of the electric push rod 205 away from the push arm 204 is connected to the frame 1. Multiple guide blocks 203 and guide grooves 202 are respectively provided on both sides and bottom of the plug-in block 2. A guide ring 3 is inserted into the outer side of the electric push rod 205. Two push arms 204 are provided between the electric push rod 205 and the plug-in block 2. The top of the guide ring 3 is connected to the frame 1. A control box 301 is connected to the bottom of the frame 1.

[0024] In practical implementation, to prevent the handcart from tipping over, before loading items, the electric push rod 205 connected to the bottom of the frame 1 is controlled by the control box 301. One end of the electric push rod 205 pushes the push arm 204 connected to it under the guidance of the guide ring 3. At this time, the two push arms 204 can open to both sides, and then push the plug block 2 along the guide groove 202 to both sides through the guide block 203 rotatably connected to it. This pushes the anti-tipping wheels 201 on both sides of the frame 1 to both sides, improving the lateral support effect of the frame 1, thereby effectively preventing the handcart from tipping over during use. The guide ring 3 can protect the connection between the electric push rod 205 and the push arm 204, preventing one of them from shifting and pulling on the other during subsequent use.
