The upper end and the front end of the fixed support 31 are respectively provided with an upper opening 33 and a side opening 34 for the handle 41 to pass through. The upper opening 33 and the side opening 34 are connected. The fixed support 31 is provided with a support surface 35 below the side opening 34. The support surface 35 is clamped with the handle 41. The distance between the support surface 35 and the top of the slot 32 is the sum of the distance from the side of the handle 41 close to the support surface 35 to the axis of the pin 42 and the radius of the pin 42. The handle 41 is provided with an end 43 extending into the fixed support 31. A cutting inclined surface 44 is provided on the side of the end 43 away from the side opening 34. A first cutting angle 45 is provided between the cutting inclined surface 44 and the end 43. The distance between the axis of the pin 42 and the cutting inclined surface 44 is less than the distance between the axis of the pin 42 and the inner wall of the fixed support 31 on the side away from the side opening 34. One end of the cutting inclined surface 44 away from the first cutting angle 45 is provided with a second cutting angle 46. The second cutting angle 46 is located inside the fixed support 31. The length of the slot 32 is greater than the radius of the handle 41. The connection line between the support surface 35 and the lower end of the slot 32 is inclined at 60 degrees on the horizontal plane.

[0038] Reference Figure 1 and Figure 3 , the vehicle frame includes a side frame 11, a bottom frame 12, and a cargo frame 13. The side frame 11 is fixedly connected to the bottom frame 12. The cargo frame 13 is installed on the side frame 11. The fixed support 31 is fixedly connected to the side frame 11. Goods are placed on the cargo frame 13 so that the vehicle frame can stably support the goods and realize the function of moving the vehicle frame to carry the goods. The front end of the bottom frame 12 is provided with a front hanging slot 14. Two hanging plates 21 are fixedly installed on the bottom frame 12. The hanging plates 21 are provided with round holes 22. The hanging plates 21 are provided with square slots 23 below the round holes 22. The square slots 23 are connected to the round holes 22. The width of the square slots 23 is less than the width of the round holes 22. The square slots 23 are located below the round holes 22. A hanging pin 24 is inserted through the hanging plates 21. The diameter of the hanging pin 24 is less than the diameter of the round holes 22 and greater than the width of the square slots 23. Both ends of the hanging pin 24 are provided with flat positions 25 that cooperate with the square slots 23. The fixed support 31 is located at the front end of the side frame 11. The rear end of the bottom frame 12 is provided with a rear hanging slot 15. The bottom frame 12 is provided with a chamfer at the opening of the rear hanging slot 15. The bottom frame 12 is provided with pulleys 16, which play a role in facilitating the movement of the vehicle frame. There is a cavity 17 between the bottom frame 12 and the cargo frame 13. The bottom frame 12 is fixedly connected with a backing plate 18 located below the cavity 17, which can place items in the cavity 17 and play a role in facilitating use. The hanging pin 24 is located between the cavity 17 and the pulleys 16.

[0039] When it is necessary to pull the frame, turn the handle 41 downward so that the handle 41 is caught in the side opening 34. At this time, the pin 42 slides to the top of the card slot 32. Since the distance between the support surface 35 and the top of the card slot 32 is the sum of the distance from the side of the handle 41 close to the support surface 35 to the axis of the pin 42 and the radius of the pin 42, when the pin 42 is located at the top of the card slot 32, the direction from the axis of the pin 42 to the side of the handle 41 close to the support surface 35 is the vertical direction. Therefore, the handle 41 extends horizontally at this time, so that when the pin 42 is at the top of the card slot 32, the handle 41 is in a horizontal state, thus facilitating the pulling of the frame through the handle 41.

[0040] When it is not necessary to pull the frame, turn the handle 41 upward so that the handle 41 slides from the side opening 34 into the upper opening 33. Then, the pin 42 slides downward under the action of gravity to the bottom of the card slot 32, and the handle 41 is inserted downward with the pin 42 into the fixed support 31, and the side wall of the handle 41 is caught by the support surface 35 to keep the handle 41 in a vertical state, so as to effectively reduce the floor area of the collapsible hand-held turnover trolley, achieve the effect of reducing the external dimensions, and facilitate the use in areas with relatively small space.

[0041] This embodiment has the following advantages:

[0042] After the handle 41 is turned to the vertical state, the handle 41 and the pin 42 can be kept in a lower position under the action of gravity. At this time, the side wall of the handle 41 is caught by the support surface 35 to keep the handle 41 in a vertical state, and at the same time, the action of gravity is used to prevent the handle 41 and the pin 42 from accidentally sliding upward, so that the side wall of the handle 41 remains in the state of being caught by the support surface 35, preventing the handle 41 from accidentally turning over, achieving the advantage of better stability.

[0043] The distance between the axis of the pin 42 and the cutting inclined surface 44 is less than the distance between the axis of the pin 42 and the inner wall of the fixed support 31 on the side far from the side opening 34, preventing the cutting inclined surface 44 and the end portion 43 from colliding with the fixed support 31 during the process of the handle 41 rotating around the pin 42, and preventing the handle 41 from being stuck and unable to turn over, playing a role in improving the reliability.

[0044] When the cutting inclined surface 44 is cut on the handle 41, a second cutting angle 46 will be formed on the side wall of the handle 41. By arranging the second cutting angle 46 inside the fixed support 31, it is possible to prevent people or objects from colliding with the second cutting angle 46, playing a role in improving safety.

[0045] The length of the card slot 32 is greater than the radius of the handle 41, so that when the handle 41 moves downward to a lower position, it can be ensured that the support surface 35 can support the handle 41 to a vertical state.

[0046] The connecting line between the supporting surface 35 and the lower end of the clamping groove 32 is inclined at 60 degrees on the horizontal plane, ensuring that the handle 41 is inserted downward into the fixed support 31 to a sufficient depth, which can prevent the unstable situation caused by the excessive angle between the supporting force generated by the supporting surface 35 on the handle 41 and the horizontal plane, play a role in preventing the handle 41 from accidentally turning downward, and at the same time will not cause the clamping groove 32 to be too long and lead to inconvenience in use.

[0047] After the handle 41 is turned to the vertical state, it is convenient to hang towing equipment such as a trailer on the hanging pin 24, and the hanging pin 24 and the vehicle frame are pulled to move by the towing equipment, so that the vehicle frame can be pulled in various ways, playing a role in improving the applicability.

[0048] Through the setting of the round hole 22, the hanging pin 24 can be inserted into the round hole 22 and penetrate through the hanging plate 21. When both ends of the hanging pin 24 are located at both ends of the two hanging plates 21, the hanging pin 24 is rotated to make the surface of the flattened position 25 in the vertical state and snap downward into the square groove 23, so that the hanging pin 24 can be clamped with the hanging plate 21 in the axial direction of the hanging pin 24, preventing the hanging pin 24 from accidentally sliding out of the hanging plate 21, playing a role in improving the reliability of the hanging pin 24.

[0049] Through the setting of the rear hanging position groove 15, it is convenient to install a hook that cooperates with the hanging pin 24 in the rear hanging position groove 15, so that the function of connecting the front and rear of different foldable hand-held turnover carts can be realized, and it is convenient to tow multiple foldable hand-held turnover carts to move at the same time.

[0050] The hanging pin 24 is arranged between the cavity 17 and the pulley 16, so that there is a large operating space at the hanging pin 24, which is convenient to connect a hook or towing equipment to the hanging pin 24, playing an effect of convenient use.

[0051] According to the disclosure and teaching of the above specification, those skilled in the art of the present invention can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
