The upper pin hole 26 and the lower pin hole 23 on the rear side are also opposite to each other due to the left and right misalignment, and the shaft hole 35 is formed on the rear side. The pin shaft 34 is detachably installed in the shaft holes 35 on the front and rear sides to connect the first connecting seat 24 and the third connecting seat 8 together to form a trolley.

[0073] Specifically, third protrusions 22 are provided on the front and rear sides of the third connecting seat 8, and the lower pin hole 23 is arranged on the third protrusion 22. The above-mentioned mounting frame 3 includes two mounting plates 19, and an accommodating space 11 is provided between the two mounting plates 19. The two mounting plates 19 are provided with a third locking hole 18 connected to the accommodating space 11. When the folding bracket 6 is rotated to the unfolded state and the first connecting seat 24 and the third connecting seat 8 are aligned up and down, because the first protrusion 25 and the third protrusion 22 on the same side are misaligned, the upper pin hole 26 and the lower pin hole 23 on the same side are relatively combined to form an axis hole 35, and the first protrusion 25 and the third protrusion 22 on the front side are inserted into the accommodating space 11, so that the upper pin hole 26 and the lower pin hole 23 on the front side are opposite to the third locking holes 18 on the left and right sides. The pin shaft 34 passes through the upper pin hole 26, the lower pin hole 23 and the third locking hole 18, and the folding bracket 6 is locked to rotate relative to the mounting frame 3, so that the folding bracket 6 is kept in the unfolded state.

[0074] The steering rod 20 can be completely removed from the storage module by removing the pins 34 on both the front and rear sides, so that the operating module 37 can be separated from the storage module.

[0075] Figure 2 As shown, preferably, when the folding bracket 6 is in the unfolded state, the mating surface 9 of the third connecting seat 8 for mating with the first connecting seat 24 is arranged obliquely upward, and the steering rod 20 mounted on the third connecting seat 8 through the first connecting seat 24 is arranged obliquely, so as to facilitate the user to apply force to push the cart forward.

[0076] In addition, when the folding bracket 6 is rotated to the unfolded state, the folding bracket 6 is tilted backward and at least partially extends out of the rear side of the front truck bed 1. The third connecting seat 8 is arranged on the portion of the folding bracket 6 extending backward to facilitate the installation of the operating module 37.

[0077] When the operating module 37 and the storage module are combined to form a trolley, the connecting rod 10 is rotated downward to a vertical state and accommodated in the above-mentioned accommodating space 11, so that the connecting rod 10 will not push back to a person in the trolley state and will not hinder the installation of the operating module 37.

[0078] This patent combines the storage module, the operating module 37 and the carrying module 36 according to the user's own needs to achieve different usage functions.

[0079] Fig. 22As shown, preferably, the above-mentioned locking pin 13 and pin shaft 34 are both spring pin shaft 61, one end of the spring pin shaft 61 is provided with a limiting head 62, the other end of the spring pin shaft 61 is provided with a steel ball 63 partially protruding from the circumferential side wall, and the spring pin shaft 61 is provided with an unlocking button 64. After the unlocking button 64 is pressed, the steel ball 63 can be retracted into the spring pin shaft 61, and the spring pin shaft 61 is stuck on both sides of the passed hole through the limiting head 62 and the steel ball 63 to prevent the spring pin shaft 61 from detaching from the passed hole, thereby playing a connecting role. When the spring pin shaft 61 needs to be removed, the steel ball 63 is retracted into the spring pin shaft 61 by pressing the unlocking button 64, and the steel ball 63 is no longer stuck on one side of the hole to limit the movement of the spring pin shaft 61, so that the spring pin shaft 61 can be removed outward from the passed hole, and the structure of the spring pin shaft 61 can achieve quick disassembly and assembly.

[0080] The spring pin 61 is an existing structure, and reference may be made to patent CN205001323U.
