[0050] During assembly, four bottom frame assembly parts 1201 are respectively fitted onto four uprights 130 to determine the position of the four uprights 130. Then, the side bracket 20 is installed between the front and rear uprights 130, with the front and rear sides of the side bracket 20 connected to the uprights 130 respectively. The lower side of the side bracket 20 abuts against the bottom frame assembly parts 1201, which provide support and limit the movement. Finally, four top frame assembly parts 1101 are installed onto the four uprights 130, working together with the bottom frame 120 to fix the position of the four uprights 130, thereby fixing the side bracket 20. The assemblies then form the frame 10 of the handcart.

[0051] Regarding the connection method between the top frame assembly 1101 and the bottom frame assembly 1201 and the column 130, in this embodiment, the handcart further includes an outer fastener 50.

At this time, the through hole of the top frame assembly part 1101 and the assembly hole 610 of the inner fitting 60 are on the same axis. The locking bolt 70 passes through the through hole of the top frame assembly part 1101 and connects with the assembly hole 610 of the inner fitting 60 at the top of the through groove 132, thereby locking the top frame 110 on the column 130. When installing the pulley 40, the assembly post of the pulley 40 is connected to the assembly hole 610 of the inner fitting 60 located at the bottom of the through groove 132, thereby installing the pulley 40 at the bottom of the frame 10.

[0056] In this embodiment, the interior fitting 60 is provided with a mounting hole 620 in the radial direction. The mounting hole 620 is inserted and engaged with the positioning post 520 of the outer fastener 50. In order to determine the relative position of the interior fitting 60 on the column 130 and prevent it from falling off, after the interior fitting 60 is assembled into the through groove 132, the mounting hole 620 and the positioning hole 131 are coaxially arranged. The positioning post 520 is sequentially inserted into the positioning hole 131 and the mounting hole 620 to fix the interior fitting 60.

[0057] Furthermore, the internal fitting 60 is composed of two internal nuts assembled separately.

[0058] In this embodiment, the side bracket 20 is provided with mounting slots 230 corresponding to the column 130 on both its front and rear sides, and the mounting slots 230 are engaged with the column 130. When the column 130, the top frame 110, and the bottom frame 120 form a frame 10, its structure is fixed, and the side bracket 20 can be stably fixed to the frame 10.

[0059] In this embodiment, the side support 20 includes multiple side support components 220, which are stacked vertically to be combined with uprights 130 of different specifications to form handcarts of different heights. Each side support component 220 is provided with at least one support strip 210, and the front end and / or rear end of the support strip 210 is provided with a blocking part 2101. In order to prevent the carrying unit 30 from falling off the handcart due to inertia during transportation, this embodiment uses the blocking part 2101 to block the carrying unit 30, preventing it from flying off due to inertia. When it is necessary to remove the carrying unit 30, it is only necessary to raise the carrying unit 30 above the blocking part 2101.

[0060] In this embodiment, the handcart also includes a top cover and a bottom plate. The top cover is connected to the top frame 110, and the bottom plate is connected to the bottom frame 120.
