[0027] As Figure 3As shown in the figure, a further improvement of the technical solution lies in that the clamping assembly 3 includes a fixed frame 16 and two pressing plates 10. The fixed frame 16 is installed on the top of the frame body 4. One of the pressing plates 10 is installed on the fixed frame 16. A plurality of connecting plates 12 are rotatably connected between the two pressing plates 10. A plurality of connecting plates 12 are rotatably connected to both the top and bottom of one of the pressing plates 10. One end of the connecting plate 12 away from one of the pressing plates 10 is rotatably connected to the other pressing plate 10. A lever 11 is provided at the position of the rotating shaft of one of the connecting plates 12 and the pressing plate 10. The lever 11 is shaped like a U. The lever 11 rotates on the pressing plate 10. The penetrating part of the connecting plate 12 and the lever 11 is fixedly connected. A torsion spring 13 is sleeved on the outer circumference of the lever 11, and both ends of the torsion spring 13 are fixed to the lever 11 and the pressing plate 10 respectively. An electric push rod 15 is installed on one side of the fixed frame 16. The output end of the electric push rod 15 is installed with a push plate 14. One side of the push plate 14 abuts against the lever 11, and the push plate 14 is used to drive the lever 11 to rotate.

[0028] As Figure 2 shown in the figure, a further improvement of the technical solution lies in that a plurality of second moving wheels 8 are installed at the bottom of the frame body 4. Two reduction motors 5 are installed on the frame body 4. Two first moving wheels 7 for supporting the bottom of the sliding frame 1 are installed. One ends of the output shafts of the two reduction motors 5 are respectively fixed to the connecting shafts of two of the second moving wheels 8. Thus, by starting the reduction motors 5, the reduction motors 5 drive the second moving wheels 8 to rotate, thereby realizing the driving of the transport vehicle, further improving the automation of the transport vehicle and making it more labor-saving.

[0029] A further improvement of the technical solution lies in that adsorption components are provided on both sides of the end of the pin 17. The adsorption components are magnetic blocks 20. The magnetic blocks 20 are installed on the pin 17. The magnetic blocks 20 are magnetically connected to the counterbore holes on the sliding frame 1, so that the pin 17 is adsorbed and fixed in the counterbore holes.

[0030] A further improvement of the technical solution lies in that buckle pulling grooves 21 are provided on both sides of the ends of a plurality of pins 17, and chamfered corners 22 are provided at the bottom ends of a plurality of pins 17, so as to facilitate the operation of the staff to take out and insert the pins 17.

[0031] A further improvement of the technical solution lies in that a plurality of rubber pressing blocks 9 are installed on one side of the other pressing plate 10. Anti-slip V grooves are provided on one side of the plurality of rubber pressing blocks 9, so as to effectively improve the friction between the pressing plate 10 and the article.

A plurality of anti-slip lines are provided on the outer circumferential wall of the U-shaped pipe, so as to facilitate dealing with the situation of damage of the power component, and then the staff manually pushes the transport vehicle.

[0033] By moving the carriage 1 outward along the chute 18 opened on the support platform 2 to a suitable position, the carriage 1 is thus unfolded, and the area of the support platform 2 is enlarged, thereby facilitating the handling of larger items. At the same time, the clamping component 3 clamps and fixes the items on the support platform 2 to prevent the items from tilting and falling during handling. Moreover, the power component drives the second moving wheel 8 to rotate, thereby realizing the driving of the trolley, and further improving the automation of the trolley, making it more labor-saving.

[0034] By pulling out the pin 17 upward, the pin 17 is disengaged from the pin hole 19, thereby also releasing the locking state between the carriage 1 and the support platform 2, and thus facilitating the adjustment of the position of the carriage 1. After the adjustment is completed, the pin 17 can be inserted into the pin hole 19 through the counterbore, so that the carriage 1 and the support platform 2 are re-locked and fixed.

[0035] When the electric push rod 15 extends, the push plate 14 squeezes the lever 11, so that the lever 11 drives the connecting plate 12 to rotate. The rotation of the connecting plate 12 drives the pressing plate 10 to shift inward and clamp and fix the items on the support platform 2, thereby effectively improving the stability of the items during handling. At the same time, the torsion spring 13 can assist the connecting plate 12 to rotate reversely and reset.

[0036] During the working process of this embodiment:

Then, the carriage 1 is pulled outward, and the carriage 1 is moved outward along the chute 18 opened on the support platform 2 to a suitable position. Then, the pin 17 is inserted into the pin hole 19 through the counterbore, so that the carriage 1 and the support platform 2 are re-locked and fixed, so that the carriage 1 is unfolded and fixed, and the area of the support platform 2 is enlarged, thereby facilitating the handling of larger items;

[0038] By starting the electric push rod 15, the electric push rod 15 extends to make the push plate 14 squeeze the lever 11, so that the lever 11 drives the connecting plate 12 to rotate. The rotation of the connecting plate 12 drives the pressing plate 10 to shift inward and clamp and fix the items on the support platform 2 to prevent the items from tilting and falling during handling, thereby effectively improving the stability of the items during handling;

[0039] When the electric push rod 15 retracts and the connecting plate 12 rotates reversely and resets, the torsion spring 13 can assist the connecting plate 12 to rotate reversely and reset;

[0040] By starting the reduction motor 5, the reduction motor 5 drives the second moving wheel 8 to rotate, thereby realizing the driving of the trolley, and further improving the automation of the trolley, making it more labor-saving.
