[0012] Furthermore, the side walls of the positioning seat are all in contact with the corresponding connecting rods.

[0013] Through the above technical solution, the positioning seat is synchronized with the corresponding connection and the corresponding rubber block clamps and fixes the connection block.

[0014] Furthermore, the load-bearing assembly includes a load-bearing rod, and the front and rear ends of the load-bearing rod are fixedly connected to the corresponding connecting rod.

[0015] Through the above technical solution, the setting of the load-bearing rods improves the load-bearing capacity of the entire stretcher.

[0016] Furthermore, the left end of the connecting rod is fixedly connected with a handle, and the outer wall of the handle is provided with an anti-slip groove.

[0017] Through the above technical solution, the handle and the anti-slip groove cooperate with each other, making the stretcher more stable when being lifted.

[0018] Furthermore, shoulder straps are provided at the front and rear portions of the outer wall of the load-bearing rod.

[0019] Through the above technical solution, the shoulder straps arranged on the outer wall of the load-bearing rod can share the pressure on the hands of the staff, making it easier to use the stretcher.

[0020] Furthermore, the nylon cloth and the nylon short cloth are both made by interweaving nylon fibers, and the connecting rods are both made of thickened aluminum alloy tubes.

[0021] Through the above technical solution, the strength of the entire stretcher is higher and the service life is longer. Beneficial Effects

[0022] The utility model provides a portable lightweight stretcher. Compared with the prior art, it has the following beneficial effects:

[0023] (1) The portable lightweight stretcher drives the nylon cloth to unfold to the left and right sides by rotating the connecting rod on the outer wall of the rotating shaft. The positioning seat is engaged with the inner wall of the connecting seat and abuts against the connecting rod. The rubber block is engaged with the outer wall of the connecting seat to limit the connecting rod. When the patient lies on the nylon cloth, he can hold the handle to drive the connecting rod and the load-bearing rod to lift up, so that the connecting rod and the positioning seat are tightly abutted, and the shoulder strap is hung on the shoulder to store and carry the stretcher. The placement seat drives the rubber block and the positioning seat to separate from the engaging state with the connecting seat and the connecting rod, and the connecting rod drives the nylon cloth to approach each other. The connecting rod rotates on the outer wall of the rotating shaft, so that the entire stretcher is folded for easy carrying. The entire stretcher is easy to store and carry. When the storage is completed, the overall angle is small and it can pass through a narrow place, making it more suitable for work. The overall strength is high and light.
