Specifically, through the setting of the screw sleeve 7, the screw rod 6 is driven to rotate by starting the motor 5, and the screw rod 6 causes the screw sleeve 7 to produce a vertical displacement along the guide rod, and the screw sleeve 7 then drives the two protective plates 3 to displace, so that the protective plates 3 can squeeze and limit the top of the goods placed in the installation box 1 and protect it, so as to avoid the situation where the goods are shaken and deviated due to bumpy roads during transportation.

[0028] Furthermore, a plurality of soft pads are fixedly installed at the bottom of the two protective plates 3. Specifically, through the setting of the soft pads, the soft pads are soft, so that the protective plates 3 can protect the goods when squeezing and limiting the top of the goods, thereby preventing the protective plates 3 from causing damage to the top of the goods due to excessive force.

[0029] Furthermore, there are four self-braking universal wheels 13, and the tops of the four self-braking universal wheels 13 are fixedly installed at the four corners of the bottom of the installation box 1. Specifically, through the arrangement of the self-braking universal wheels 13, the entire trolley can be moved and transported as a whole. When it is transported to a suitable area and braked, the goods in the trolley can be moved.

After lifting the expansion board 2 to a suitable position, the pull block 9 is released to make the spring 11 lose its tension and elastically recover to pull the pull block 9 back to its position. The pull block 9 immediately drives the pull rod 10 back to its position and inserts the plug block 12 at one end into the through hole and the socket to complete the positioning of the expansion board 2, thereby effectively and conveniently expanding the installation box 1 and improving the carrying capacity and practicality of the traction beam trolley.

[0032] By starting the motor 5 to drive the screw 6 to rotate, the screw 6 causes the screw sleeve 7 to produce a vertical displacement along the guide rod, and the screw sleeve 7 further drives the two protective plates 3 to be displaced, so that the protective plates 3 can squeeze and limit the top of the goods placed in the installation box 1 and protect it, avoiding the situation where the goods encounter bumpy roads during transportation and cause the goods to shake and deviate.
