furthermore, a retention groove 4 is formed in the side wall of the small-size shell type splint 3, the first mounting cylinder 8 slides in the retention groove 4, a placing groove 18 is formed in the small-size shell type splint 3, the small-size shell type splint 3 is 80mm long, 20mm wide and 230mm deep and used for placing certain medicines for fracture fixation and first aid and can be drawn out for use in wartime or emergency, and the volume of the retention groove 4 is 10cm3 and can be used for placing medicines or injections so as to be convenient for patients to use;

further, two fixing grooves 5 are formed in the side wall, away from the middle shell type clamping plate 2, of the large shell type clamping plate 1, the two fixing grooves 5 are symmetrically arranged, the two large shell type clamping plates 1 are fixed through fixing bolts 20, and two ends of each fixing bolt 20 are connected with the two adjacent fixing grooves 5 in the large shell type clamping plates 1 respectively;

further, the elastic belt 19 is wound with the outside of the large shell type splint 1, the front surface of the elastic belt 19 is a nylon hair surface, and the back surface is a nylon hook tooth surface.

In the embodiment of the large-size shell type splint 1, for the fracture fixation of single limbs such as thighs, shanks, forearms and upper arms of a human body, the total number of the large-size shell type splint 1, the medium-size shell type splint 2 and the small-size shell type splint 3 is two according to the specific parts of the limbs, the large-size shell type splint 1, the medium-size shell type splint 2 and the small-size shell type splint 3 are respectively placed on the inner side and the outer side of the limb to be fixed correspondingly, and then two elastic belts 19 are used for winding and fixing the two ends of the shell type splint.

In the embodiment, the shell type splint 2 is fixed on the whole lower limb or upper limb of a human body, after the large shell type splint 1, the medium shell type splint 2 and the small shell type splint 3 are nested, the medium shell type splint 2 can be directly extracted to the outside by the corresponding length relative to the large shell type splint 1, the medium shell type splint can be automatically fixed at the corresponding position of the far end of the large shell type splint 1 due to the action of the first limiting mechanism, then the length of the small shell type splint 3 relative to the medium shell type splint 2 is extracted to the outside in sequence, and the small shell type splint 3 can be automatically fixed at the corresponding position of the far end of the medium shell type splint 2 due to the action of the second limiting mechanism, so that shell type fixing splints with different lengths are formed. Because the number of first spacing groove 6 and second spacing groove 7 is a plurality of to make the fixed splint combination length of shell type have multiple different length, and then can make up and be used for different limbs length, adjust the length with the human fixed limbs length of needs back with two sets of shell type splint, place respectively in corresponding inside and outside both sides of fixed limbs of needs, then use four elastic webbing 19 at the both ends of shell type splint, and the centre winding of limbs fixed.

The embodiment of the small-size shell type splint 3 aims at the fixation of the chest and the spine of a human body, and because the volume of the spine of the human body is large, two sides of the large-size shell type splint 1 of 4 groups of the retaining grooves need to be combined side by side to form two extra-large shell type splints. Firstly, the fixing bolts 20 at the top ends of the four large-size shell type clamping plates 1 are pulled out. After the side surfaces of the two large-size shell type splints 1 are aligned, two bolt pins of one fixing bolt 20 are respectively inserted into the fixing grooves 5 formed in each large-size shell type splint 1 to fixedly combine the two large-size shell type splints 1 together. The other two large shell cleats 1 operate identically. The two combined oversized shell type splints are respectively placed on the inner side and the outer side of the spine to be fixed, and then the elastic belts 19 are wound and fixed at the two ends of the shell type splints.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
