[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] The utility model provides Figure 1-4The multi-purpose trolley shown in the figure includes a foldable bracket 1, a seat cushion 7 for riding is installed at the upper end position of the foldable bracket 1, a support frame 12 is installed at the upper end position of the foldable bracket 1 at the right position, and an angle adjustment shaft 9 is provided at the upper end position of the support frame 12. The angle adjustment shaft 9 enables the control handle 10 installed at the inner position to be adjusted in angle. A rotatable handle 11 is installed at the inner position of the control handle 10. The rotatable handle 11 is rotated by being sleeved on the inner position of the control handle 10 through a rotating shaft 16 fixed at the left and right end positions. A groove 17 is fixed at the inner position of the control handle 10, and a torsion spring 15 is sleeved at the outer position of the rotating shaft 16. The dynamic shaft 16 can drive the torsion spring 15 to move through the fixed plate 18 fixed at the outer wall position. A cushion 8 for leaning is provided at the left end position of the support frame 12. The foldable bracket 1 adjusts its direction during movement through the front steering wheel 4 at the left position of the lower end. The lower end of the foldable bracket 1 is provided with a rear moving wheel 3 at the right position, and an auxiliary wheel 13 is installed at the inner position of the rear moving wheel 3. A foldable limit rod 2 for limiting the degree of expansion is installed at the front and rear ends of the foldable bracket 1. A support rod 6 is installed at the left end position of the foldable bracket 1, and a foot pedal 5 for placing both feet is installed at the lower end position of the support rod 6. A rubber protective belt 14 is installed at the rear end position of the foot pedal 5.

[0025] The frame of the whole vehicle is made of a combination of 6061 aluminum alloy flat tubes and round tubes. It has a simple appearance and the push handle is flipped up for a more design sense. The backrest and seat cushion 7 are separated from the frame and can be quickly installed and removed, making packaging and transportation more convenient. The backrest angle is adjustable and the rider can sit or lie down, and the rider can adjust the sitting posture at will. The whole vehicle adopts a front and rear folding method, which makes the structure more stable and the force more evenly distributed.

[0026] like Figure 1 and Figure 2 As shown, the foldable bracket 1 allows the seat cushion 7 and the back cushion 8 to be close together when folded. The foldable bracket 1 is installed with the support rod 6 by bolts. The inclination angle of the support rod 6 can lift the legs of the user when sitting at the upper end position of the seat cushion 7. The foot pedal 5 and the rubber protective belt 14 allow the user to step on both feet at the upper end position. The back cushion 8 supports the back of the user. The angle between the back cushion 8 and the seat cushion 7 can be adjusted. The rotatable handle 11 can be adjusted in angle through the angle adjustment shaft 9. The rotatable handle 11 controls the moving direction of the cart.

[0027] The stroller can be easily folded and is sturdy and durable. It has an innovative folding frame, a stable, stylish, lightweight artistic frame, and eliminates unnecessary elements that interfere with the user, avoiding the clutter of the entire frame. The frame uses square tubes, which highlights the minimalist style while making it look fuller. The seat back is designed according to ergonomics to make the passengers more comfortable.

[0028] like Figure 3 and Figure 4 As shown, the front steering wheel 4 can be rotated at any angle so that the user can adjust the direction during movement. The diameter of the rear moving wheel 3 is larger than the diameter of the front steering wheel 4. The foldable bracket 1 can be moved by the auxiliary wheel 13 when in the folded state. The foldable bracket 1 is limited to the maximum degree of unfolding by the foldable limit rod 2 when unfolded. The rotatable handle 11 can be rotated at the inner position of the control handle 10. The rotatable handle 11 is rotated by the rotating shaft 16. The rotation of the rotating shaft 16 causes compression of the torsion spring 15 through the fixed plate 18. The other side of the torsion spring 15 is clamped at the inner position of the groove 17.

[0029] The device is equipped with a rotatable handle 11 on the inner side of the control handle 10. When the staff pushes the cart with force or encounters an obstacle on the road, the rotatable handle 11 will rotate, and the rotation will compress the torsion spring 15, causing the torsion spring 15 to store energy. The rotatability of the rotatable handle will provide inertia when encountering an obstacle, preventing the handle from slipping out of the hand in an instant. After the obstacle is overcome with force, the torsion spring 15 releases energy to return the rotatable handle 11 to its original position.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
