[0036] Working principle:

[0037] Step 1: One of the three downward-pointing support claw arms 20 is the direction for inserting the mattress. The three downward-pointing support claw arms 20 only occupy half of the space of the sphere, so align the mattress insertion direction.

[0038] Step 2: Adjust the positions of the locking screw 80, the vertical through hole 631, and the threaded hole 531 to ensure a moderate placement gap 90;

[0039] Step 3: Place the mattress into the mattress storage assembly 200 and adjust the top rotating mechanism 300 to the appropriate position;

[0040] Step 4: Start moving or transporting the mattress and unload it after arriving at the designated location.

[0041] In the first aspect of the present invention, as a preferred embodiment, the downward-reaching support claw arm 20 is composed of multiple rectangular mounting frames 201, with adjacent rectangular mounting frames 201 being detachably connected. The use of rectangular mounting frames 201 allows for the tailored design of large mattress auxiliary transport devices of varying sizes, providing increased adaptability.

[0042] In the first aspect of the present invention, as a preferred embodiment, the downward support claw arm 20 includes a top connecting arm 21, a middle connecting arm 22, and a lower vertical connecting arm 23. The two ends of the middle connecting arm 22 are connected to the top connecting arm 21 and the lower vertical connecting arm 23 respectively. The angle between the extension direction of the top connecting arm 21 and the extension direction of the lower vertical connecting arm 23 is A1 and is an obtuse angle, and the angle between the extension direction of the top connecting arm 21 and the extension direction of the middle connecting arm 22 is A2 and is an obtuse angle. Specifically, A2>A1, and A2 is between 150°-170°. The purpose of setting the "lower vertical connecting arm 23" is to improve the overall stability.

[0043] It's important to note that the three downward-pointing support claws 20 only occupy half of the spherical space, ensuring proper alignment when inserting the mattress. These claws 20 also provide a stable support point, facilitating both inserting and removing the mattress and ensuring stability. The downward-pointing support claws 20 comprise a first, second, and third inclined section, each formed by a rectangular mounting frame 201. The second inclined section is hinged or fixed to the ends of the first and third inclined sections.

[0044] In the first aspect of the present invention, as a preferred embodiment, the bottom wheel assembly 30 includes an upper connecting plate 31, a side bracket 32, and a roller assembly 33. The upper connecting plate 31 is fixed to the side bracket 32, and the roller assembly 33 is rotatably mounted on the side bracket 32. The upper connecting plate 31 is provided with an auxiliary placement column 34 along the inner side. The auxiliary placement column 34 has an upper curved end surface 341 to facilitate the placement of the mattress into the mattress storage assembly 200.

[0045] In the first aspect of the present invention, as a preferred embodiment, the locking screw 80 includes a gripping portion 81 and a threaded portion 82, wherein the gripping portion 81 is connected to the threaded portion 82. The gripping portion 81 includes a top cover 811, a middle connecting column 812, and a lower connecting portion 813, wherein the upper and lower ends of the middle connecting column 812 are connected to the top cover 811 and the lower connecting portion 813, respectively. The mattress storage assembly 200 also includes a middle tension spring 70, wherein the ends of the middle tension spring 70 are connected to the first receiving member 50 and the second receiving member 60, respectively. The middle tension spring 70 is located in the upper middle portion of the first receiving member 50. The entire device has a compact structure and is easy to operate.

[0046] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
