A headboard 2 is installed at the head of the main bed frame 6, and a footboard 3 is installed at the tail of the main bed frame 6. The height of the headboard 2 is higher than the height of the footboard 3. Both the headboard 2 and the footboard 3 are provided with grooves. The function of the grooves is to facilitate the user to hold the headboard 2 or the footboard 3 through the grooves when the auxiliary bed is moved, thereby improving the stability of the auxiliary bed when moving; the bed board 7 includes a backboard 701, a seat board 702, a thigh board 703, and a calf board 704. The middle part of the bed board 7 is provided with a grid hole. Through the design of the grid hole, material waste can be reduced, the air permeability of the bed board 7 can be improved, the weight can be reduced, and the ventilation can be improved.

[0035] The support frame 5 is installed on the main bed frame 6, the frame body 502 of the support frame 5 is preferably in a cylindrical shape, and is hollow inside. The hollow design of the frame body 502 makes the support frame 5 lighter in weight, reduces unnecessary material waste, and facilitates the transfer of goods. The lower part of the support frame 5 is provided with a stop lever 504, and the lower part of the frame body 502 is provided with a loading and unloading hole 503. The main bed frame 6 is provided with a fixing hole 603 matched with the loading and unloading hole 503. A plunger pin 15 is arranged on the loading and unloading hole 503 and the fixing hole 603, so as to realize quick disassembly of the support frame 5. The upper part of the frame body 502 is provided with a wooden handrail 501. The wooden handrail 501 has better contact feeling than a metal handrail, and does not directly transfer cold from the metal to the user's body.

[0036] The plunger pin 15 is composed of a fixed nut 1501, a pull-out pin 1502 and a slot 1503. The fixed nut 1501 is used to fix the plunger pin 15 in the fixing hole 603 of the main bed frame 6.
