[0011] a strap, one end of which is fixedly mounted on the top of the base;

[0012] A locking assembly is arranged on the top of the base and cooperates with the strap.

[0013] With the above structure, by putting the mounting frame on one side of the bed, then rotating the first screw and cooperating through the threaded connection between the first screw and the mounting frame, the splint can be driven to move up and clamped and fixed between the bed. When the mounting frame is fixed, rotating the second screw and cooperating through the threaded connection between the second screw and the movable frame can drive the movable frame and the base to move laterally. At this time, by adjusting the lateral position of the base, the base can be adjusted to be directly under the patient's limbs according to the position of the patient lying on the bed, which is convenient for precise fixation of the patient's limbs. Here, by rotating the third screw and cooperating through the threaded connection between the third screw and the base, the base can be driven to move up and down and the distance between the base and the bed can be adjusted, so that the base can adapt to different bed levels for stable contact support, thereby improving the support stability of the base for the patient's limbs.

[0014] Preferably, rubber pads are fixedly mounted on the top inner wall of the mounting frame and the top of the clamping plate, and the two rubber pads are in contact with the top and bottom of the bed body respectively.

[0015] Furthermore, the installation stability between the installation frame and the bed can be improved by providing a rubber pad.

[0016] Preferably, a stabilizing rod is fixedly mounted on the bottom of the clamping plate, and the bottom end of the stabilizing rod passes through the bottom inner wall of the mounting frame and is slidably connected to the mounting frame.

[0017] Furthermore, the stability of the lifting and lowering of the clamping plate can be improved by providing a stabilizing bar.

[0018] Preferably, a support cushion is fixedly installed on the top of the base, and the support cushion cooperates with the strap.

The clamping rod is fixedly sleeved on the rotating shaft. The bottom end of the clamping rod is respectively matched with the plurality of teeth. The top end of the clamping rod passes through the top inner wall of the adjusting box and extends to the outside of the adjusting box. The bottom end of the spring is fixedly mounted on the top of the clamping rod. The mounting block is fixedly mounted on the top inner wall of the adjusting box. The top end of the spring is fixedly mounted on the mounting block.

[0021] Furthermore, by tying the strap around the patient's limbs and then passing the left end of the strap through the two through holes on the adjustment box, the strap can be tightened by pulling the strap. When the strap is tightened, the bottom end of the clamping rod and the multiple teeth are in a slipping state. Then, when the strap is tightened and firmly bound to the patient's limbs, the strap is loosened. At this time, the corresponding teeth clamp the bottom end of the clamping rod, which can limit the right movement of the strap, thereby limiting the position and fixing the strap to ensure the stability of the strap on the patient's limbs. At this time, by toggling the top of the clamping rod, the clamping rod can be rotated and the spring can be compressed.

[0025] Furthermore, by rotating the fourth screw and cooperating through the threaded connection between the fourth screw adjustment box, the limit head can be driven to move its position. Here, when the limit head moves to the right, it can squeeze the card rod and make the card rod and the corresponding teeth stably clamped, avoiding the separation between the card rod and the teeth, and when the limit head moves to the left, the extrusion limit of the limit head and the card rod can be released. At this time, it is convenient for personnel to move the card rod, which facilitates the unlocking and clamping between the card rod and the teeth.

[0026] Preferably, a perforated plate is fixedly mounted on the left end of the binding strap, and the perforated plate matches the two through holes respectively.

[0027] Furthermore, by providing the perforated plate, it is easy for the strap to pass through the two through holes and is convenient for people to pull.

[0028] The beneficial effects of the present invention are:

[0029] 1. By putting the mounting frame on one side of the bed body, and then rotating the first screw and cooperating through the threaded connection between the first screw and the mounting frame, the splint can be driven to move up and clamped and fixed between the bed body. When the mounting frame is fixed, rotating the second screw and cooperating through the threaded connection between the second screw and the movable frame can drive the movable frame and the base to move laterally. At this time, by adjusting the lateral position of the base, the base can be adjusted to be directly under the patient's limbs according to the position of the patient lying on the bed body, so as to facilitate accurate fixation of the patient's limbs. Here, by rotating the third screw and cooperating through the threaded connection between the third screw and the base, the base can be driven to move up and down and the distance between the base and the bed body can be adjusted, so that the base can adapt to different bed levels for stable contact support, thereby improving the support stability of the base for the patient's limbs;

[0030] 2. Tie the strap around the patient's limb, then pass the left end of the strap through the two through-holes on the adjustment box, and then pull the strap to tighten the strap. When tightening the strap, the bottom end of the clamping rod and the multiple teeth are in a slipping state. Then, when the strap is tightened and firmly bound to the patient's limb, loosen the strap. At this time, the corresponding teeth clamp the bottom end of the clamping rod, which can limit the right movement of the strap, thereby limiting the strap from moving to the right, thereby ensuring the stability of the strap on the patient's limb. At this time, by toggling the top of the clamping rod, the clamping rod can be rotated and the spring can be compressed. At this time, the bottom end of the clamping rod can be released from the corresponding teeth, and the strap can be pulled out from the right side of the adjustment box, making it easy to unlock the strap.

[0031] 3. By rotating the fourth screw and cooperating with the threaded connection between the fourth screw adjustment box, the limit head can be driven to move its position. Here, when the limit head moves to the right, it can squeeze the clamping rod and make the clamping rod and the corresponding tooth stably clamped to prevent the clamping rod from being separated from the tooth. When the limit head moves to the left, the squeeze limit between the limit head and the clamping rod can be released, and it is convenient for personnel to toggle the clamping rod to facilitate the unlocking and clamping between the clamping rod and the tooth.

[0032] The present invention can stably support and place the device as a whole on the bed by arranging the cooperation between the base and the strap, and can achieve stable fixation between the fixing device as a whole and the bed, thereby improving the stability of the fixing device in use. At the same time, by arranging the cooperation between the locking assembly and the strap, it can be suitable for binding and fixing the limbs of patients with different thicknesses, thereby ensuring applicability and stability.
