Any modifications, substitutions and alterations made based on ordinary technical knowledge and conventional means in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0019] Reference Figure 1 and Figure 2 ,like Figure 1 , Figure 2As shown, the rescue stretcher folding and quick-release device mainly consists of two parts: a first stretcher assembly 1 and a second stretcher assembly 2, which are connected by pins to achieve folding and unfolding functions. Other components include a clamping plate assembly 3 and a buckle plate 5 installed on the first stretcher assembly 1, and a tube assembly 4 and a bending plate 6 installed on the second stretcher assembly 2.

[0020] Both the first stretcher assembly 1 and the second stretcher assembly 2 are long, rectangular frame structures assembled from multiple slats. The rear end of the first stretcher assembly 1 is rotatably connected to the front end of the second stretcher assembly 2. A lug plate is provided at the rear end of the first stretcher assembly, and an inverted U-shaped buckle is provided at the front end of the second stretcher assembly. Mounting holes are provided on the lug plates, corresponding to the inner grooves of the inverted U-shaped buckles. A pin passes through the mounting holes and the inner grooves to connect the first stretcher assembly 1 and the second stretcher assembly 2, and nuts are provided at both ends of the pin for fixation. The first stretcher assembly 1 and the second stretcher assembly 2 can rotate around the pin.

[0021] A clamping plate assembly 3 is connected to the lower front end of the first stretcher assembly 1 via a cylinder. The clamping plate assembly 3 is snapped onto the rear end of the vehicle, thus fixing one end of the quick-release folding device of the rescue stretcher to the rear of the vehicle. The quick-release folding device of the rescue stretcher is connected to the vehicle's passenger seat via a pin at the vertical end of the ear plate and the inverted U-shaped buckle. The quick-release device can be unfolded and folded along with the seat, allowing it to stand upright. A tube assembly 4 is located at the rear end of the second stretcher assembly 2. The tube assembly 4 consists of two handles, with the outer handle connected to the fixing clamping plate at the front of the vehicle via a telescopic spring handle. Specifically, the handle is inserted into a slot for fixation when unfolded and can be quickly pulled out when folding is required.

[0022] When folded, the second stretcher assembly 2 rotates 180 degrees counterclockwise along the pin shaft to fit against the first stretcher assembly. The tube assembly 4 on the second stretcher assembly 2 is fastened to the buckle plate 5 of the first stretcher assembly 1, saving space in the passenger seat. The buckle plate 5 in the middle of the quick-release device can fix the two main parts in place when folded, preventing shaking during driving. When placing the rescue stretcher, push the head crossbar against the head plate of the rescue stretcher, and then place the tail support legs into the tail support leg slots of the rescue stretcher for quick assembly and disassembly.
