The parts of the flexible wrapping member 3 that contact the inner wall of the connecting frame 2a are fixedly connected to each other. The bottom of the flexible wrapping member 3 has a through cavity 4 for the limb to pass through. The spacing between the two guide plates 1b is greater than the width of the through cavity 4. The flexible wrapping member 3 is filled with liquid 5. The flexible wrapping member 3 has two reciprocating motion components 6 fixedly installed on the top seat 2. The reciprocating motion component 6 includes a threaded rod 6a that penetrates the flexible wrapping member 3 and is rotatably connected to the connecting frame 2a, a slider 6b that is threadedly connected to the threaded rod 6a, and a guide rod 6c that penetrates the slider 6b and is slidably connected to the slider 6b. The threaded rod 6a is configured to be closed. The two-way return threaded rod 6a is provided, so that when the threaded rod 6a rotates in the same rotation direction, the slider 6b will move back and forth on the threaded rod 6a, the guide rod 6c penetrates the flexible wrapping member 3 and is fixedly connected to the inner wall of the connecting frame 2a, and a toggle member 7 is installed on the slider 6b. The toggle member 7 includes a transmission shaft 7a that penetrates the slider 6b and is rotatably connected to the slider 6b, a transmission gear 7b that is fixedly connected to the top of the transmission shaft 7a, a rack 7c that meshes with one side of the transmission gear 7b, and a toggle plate 7d that is fixedly connected to the outer circumference of the transmission shaft 7a, the rack 7c penetrates the flexible wrapping member 3 and is fixedly connected to the inner wall of the connecting frame 2a, and a toggle plate 7d is installed on the output end of the reciprocating motion component 6. A toggle member 7 moves in the liquid 5, a motor 8 is also installed in the connecting frame 2a, a threaded rod 6a passes through the connecting frame 2a at one end close to the motor 8, and two threaded rods 6a pass through one end of the connecting frame 2a and are fixedly connected to a first bevel gear 9, a power shaft 10 is rotatably installed on one side of the connecting frame 2a, and second bevel gears 11 meshing with the two first bevel gears 9 are respectively installed at both ends of the power shaft 10, the end of the output shaft of the motor 8 is fixedly connected to the end of one of the threaded rods 6a, and a water pipe 12 connected to the inside of the flexible wrapping member 3 is also fixedly installed on the connecting frame 2a, the water pipe 12 does not contact the guide plate 1b, and a valve can be installed on the water pipe 12; First, the patient places the arm or leg on the bottom plate 1a, and then the medical staff puts the connecting frame 2a between the two guide plates 1b and moves it downward. At this time, the patient's limb passes through the through hole 2b. Since there is no liquid 5 in the flexible wrapping piece 3, the flexible wrapping piece 3 is in a wrinkled state. Then the medical staff opens the valve and injects the warm liquid 5 into the flexible wrapping piece 3 through the water pipe 12. As the liquid 5 is injected, the flexible wrapping piece 3 gradually deforms under the action of the liquid 5 and is applied to the surface of the limb. When the liquid 5 is Figure 4 After the top of the through cavity 4 is submerged and the two sides of the flexible wrapping member 3 are connected, the injection of the liquid 5 into the flexible wrapping member 3 is stopped, or the water pipe 12 is directly connected to the external warm liquid 5 at all times, so as to maintain the liquid level and temperature; In the initial state, one of the toggle members 7 on the two reciprocating motion components 6 is close to the motor 8, and the other is away from the motor 8. The medical staff drives the motor 8 to work, and the output shaft of the motor 8 drives the threaded rod 6a. The threaded rod 6a cooperates with the first bevel gear 9, the power shaft 10 and the second bevel gear 11 to make the other threaded rod 6a rotate synchronously. When the two threaded rods 6a rotate, the two sliders 6b will drive the two toggle members 7 to approach each other and then move away from each other, and move from one end of the threaded rod 6a to the other end respectively. Since the threaded rod 6a is a two-way return threaded rod 6a, the slider 6b will turn back when it moves to the end on the threaded rod 6a, which makes the slider 6b reciprocate on the threaded rod 6a. Of course, the two-way return threaded rod 6a may not be used, but the motor 8 needs to rotate forward and reverse regularly; When the slider 6b moves, it will drive the transmission shaft 7a to move. The gear on the transmission shaft 7a will rotate due to meshing with the rack 7c. The gear will drive the transmission shaft 7a to rotate. The transmission shaft 7a will drive the toggle plate 7d to rotate, and the liquid 5 around the transmission shaft 7a will be toggled to all sides. When the liquid 5 is toggled, energy will be transferred in the water, forming transverse wave-like water ripples that hit the flexible wrapping member 3 and transfer to the limbs, simulating the uniform slapping of the massage analgesic method. The flexible wrapping member 3 made of plastic material has poor heat resistance, so the temperature in the liquid 5 will be more easily transferred to the limbs, so that when the patient uses this pain reliever, he is receiving massage analgesic method and heat therapy at the same time. When the force of the tapping needs to be increased, the speed of the motor 8 can be increased to speed up the movement and rotation of the toggle member 7, and vice versa, the speed of the motor 8 can be reduced.
