[0039] Please see Figure 6 The positioning component 5 includes two hollow columns 51 for connecting various components. The hollow column 51 is fixedly connected to either the first bed board 2 or the third bed board 4. An auxiliary block 53 is slidably connected inside the hollow column 51 for connecting with the spring 54. A pull rod 52 is fixedly connected to the upper part of the auxiliary block 53 for pulling the auxiliary block 53. The pull rod 52 passes through the hollow column 51 and is movably connected to it. A spring 54 is fixedly connected between the auxiliary block 53 and the hollow column 51 for moving and resetting the auxiliary block 53. A positioning piece 55 is fixedly connected to the top of the two pull rods 52 for fixing the mattress.

[0040] Working principle: During use, when the headstock needs to be raised or lowered, the motor 613 is turned on, which drives the screw 612 to rotate. The slider 614 connected to the screw 612 is then moved to the right, and the upright 633 connected to the slider 614 is also moved. The upright 633 then moves its external hollow tube 631. Since the two ends of the hollow tube 631 are fixed with connecting posts 632, and the connecting posts 632 are connected to the moving rod 622, and the moving rod 622 is connected to the main rod 621 through the connecting rod 623, and the position of the main rod 621 is relatively fixed, when the upright 633 moves, the hollow tube 631 will drive the moving rod 622 to move to the right through the connecting posts 632, while the connecting rods 623 on both sides will assist the moving rod 622 in moving to the right. Move the moving rod 622 towards the main rod 621. The moving rod 622 will then drive the hollow tube 631 to slide upward along the upright rod 633 via the connecting column 632. At this time, the support rod 625 connected to the right connecting rod 623 will be driven upward, thereby raising the second bed board 3 and the third bed board 4 together. When it is necessary to raise the third bed board 4, the cylinder 72 is activated. The cylinder 72 will then push the auxiliary rod 73 connected to it to move to the left. The auxiliary rod 73 will then drive the lower ends of the two support rods 74 to move to the left. Since the upper ends of the support rods 74 are fixed to the third bed board 4 via the connecting seat 75, when the lower ends of the two support rods 74 move to the left, the two support rods 74 will then support the third bed board 4, causing the third bed board 4 to rise.

[0041] When laying the mattress on the hospital bed, the four corners of the mattress can be secured in the positioning piece 5. When using the positioning piece 5, pull the positioning piece 55 upward. At this time, the positioning piece 55 will drive the two pull rods 52 to move upward. The auxiliary block 53 connected to the pull rod 52 will also move upward and compress the spring 54. Then, insert one corner of the mattress between the positioning piece 55 and the bed board, and then release the positioning piece 55. At this time, the spring 54 will return to its original position after losing tension, thereby pushing the auxiliary block 53 to reset, so as to drive the pull rod 52 connected to the auxiliary block 53 and the positioning piece 55 connected to the pull rod 52 to move downward, clamping and fixing one corner of the mattress.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
