The top end of the left side of the valve plate 24 is arc-shaped, the right side of the valve plate 24 is fixedly connected with the left end of the transverse shaft 25, the transverse shaft 25 is horizontally and slidably connected with the side wall of the shell 1 through a fourth spring 26, the right end of the transverse shaft 25 is connected with the transverse cylinder 27, the transverse cylinder 27 is horizontally distributed and rotatably installed in the inner wall of the shell 1, the transverse cylinder 27 is positioned above the knocking plate 2, the inner wall of the transverse cylinder 27 is in threaded connection with the twist rod 28, the twist rod 28 is fixedly installed at the right end of the transverse shaft 25, the transverse cylinder 27 is provided with a fixed block 29, the fixed block 29 is vertically distributed, the fixed block 29 is provided with knocking plates 30 which are distributed at equal angles, at least 4 knocking plates 30 are arranged, the bottom end of the knocking plate 30 is slidably and telescopically connected with the fixed block 29 through a fifth spring 31, and the outer end of the knocking plate 30 at the bottom end is contacted with the upper end surface of the knocking plate 2 when the knocking plate 30 extends out of 1/2 length, when the valve plate 24 is in a moving state, the horizontal shaft 25 in fig. 6 will move to the right side synchronously, so the twisted rod 28 moves in the horizontal cylinder 27 synchronously and horizontally, and under the screw transmission action of the horizontal cylinder 27 and the twisted rod 28, the horizontal cylinder 27 will drive the fixing block 29 in fig. 1, fig. 7 and fig. 8 to be in a synchronous rotating state, because the centrifugal force is provided in the rotating process, the faster the rotating speed is, the larger the centrifugal force is, and therefore when the rotating speed reaches a certain degree, the knocking plate 30 will extend outwards and knock on the knocking plate 2 synchronously, and because the rotating speed is faster and the knocking plate 30 is provided with a plurality of parts, the knocking plate 2 will move up and down at the bottom end of the housing 1 at a high frequency under the knocking action of the knocking plate 30, thereby realizing the purpose of performing high-frequency back knocking operation on the back of a patient.

The working principle is as follows: in actual use, the bottom end of the shell 1 can be placed in a designated area of the back of a patient needing to be subjected to back knocking, back knocking operation is carried out according to a back knocking principle from bottom to top and from outside to inside, when the back knocking operation is carried out, a user can enable the vertical cylinder 4 to slide downwards through the handle 5, bolt locking between the shell 1 and the vertical cylinder 4 can be released before sliding, when the vertical cylinder 4 slides downwards, the knocking block 3 can move synchronously along the vertical cylinder, force is applied to the knocking plate 2, at the moment, the knocking plate 2 can move downwards along the distribution direction of the vertical cylinder 7, the knocking block 8 can directly contact with the back of the patient to realize the back knocking operation, the back knocking device needs to move in the using process, and the technical scheme is provided with the structure of the ball 10 and the like, so that a medical worker does not need to repeatedly lift the whole knocking device down, and the ball 10 directly rolls on the bottom end of the shell 1 in a telescopic manner, the whole shell 1 is moved along the back-tapping route of the back of the patient;

correspondingly, the user can also perform back knocking operation on the back of the patient by pulling the pull ring 16 when completing the bolt locking between the vertical cylinder 4 and the shell 1, and the operation is as follows:

the pull ring 16 moves up and down under the operation of human hands, at this time, the vertical shaft 17 in fig. 4 synchronously moves up and down in the vertical cylinder 4, so the pressing plate 18 in the vertical cylinder 4 can similarly repeatedly press the air bag ring 19, when the air bag ring 19 is pressed, the internal air pressure of the air bag ring 19 can enter the inside of the air inlet pipe 22 under the action of the one-way valve, when the air bag ring 19 is elastically restored, the external air can enter the inside of the air bag ring 19 through the air return pipe 21, so the air bag ring 19 is repeatedly deformed to stably input high-speed flowing air into the air inlet pipe 22, the air flow can enter the power box 23 shown in fig. 6 under the communication action of the air inlet pipe 22, because the top end of the internal valve plate 24 close to the air inlet pipe 22 is of an arc-shaped structure, under the pressing action of the air flow, the valve plate 24 can move to the right side, and the air flow in the air inlet pipe 22 can enter the air outlet pipe 15 after passing through the power box 23, as shown in fig. 3, the air flow enters the air cavity 14 through the air outlet pipe 15 and is finally ejected from the air hole 13 formed on the lower end surface of the tapping plate 2, and when the valve plate 24 moves back quickly due to the resilience of the spring, the air flow can be accelerated, so that the air flow ejected from the air hole 13 and flowing at a high speed can act on the back tapping area of the patient, and the air flow is used for performing auxiliary massage and back tapping operations on back acupuncture points, and meanwhile, certain heat dissipation and sweat resistance effects can be achieved;

when the valve plate 24 is in a moving state, the horizontal shaft 25 in fig. 6 will move to the right side synchronously, so the twisted rod 28 moves in the horizontal cylinder 27 synchronously and horizontally, and under the screw transmission action of the horizontal cylinder 27 and the twisted rod 28, the horizontal cylinder 27 will drive the fixing block 29 in fig. 1, fig. 7 and fig. 8 to be in a synchronous rotating state, because the centrifugal force is provided in the rotating process, the faster the rotating speed is, the larger the centrifugal force is, and therefore when the rotating speed reaches a certain degree, the knocking plate 30 will extend outwards and knock on the knocking plate 2 synchronously, and because the rotating speed is faster and the knocking plate 30 is provided with a plurality of parts, the knocking plate 2 will move up and down at the bottom end of the housing 1 at a high frequency under the knocking action of the knocking plate 30, thereby realizing the purpose of performing high-frequency back knocking operation on the back of a patient.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
