The outer side of the rotating sleeve 3 is fixedly connected with triangular Taylor knocker 4, a pointed knocker 41 and a buck hammer 43 at intervals. The rotating sleeve 3 is rotatably connected to the needle wheel 42. The triangular Taylor knocker 4, the pointed knocker 41, the needle wheel 42 and the buck hammer 43 are evenly distributed in the circumferential direction of the rotating sleeve 3. When the rotating sleeve 3 rotates, the triangular Taylor knocker 4, the pointed knocker 41, the needle wheel 42 and the buck hammer 43 are driven to rotate, thereby changing the percussion mode. The handle 1 is provided with a replacement mechanism 5, the connecting member 2 is provided with a positioning mechanism 6 for positioning the rotating sleeve 3, and the connecting member 2 is provided with a control mechanism 7.

[0028] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the replacement mechanism 5 includes a connecting shaft 51, a winding wheel 52, a gear ring 53, a gear 54, a pull rope 55, a lifting block 56, a compression spring 57, a handle 58 and a volute spring 59. The middle part of the connecting member 2 is fixedly connected to the connecting shaft 51, and the winding wheel 52 is rotatably connected to the connecting shaft 51 in a front-to-back symmetrical manner. The volute spring 59 is connected between the winding wheel 52 and the connecting shaft 51. The winding wheel 52 is connected to the gear 54 through a one-way connector. The gear ring 53 is symmetrically fixed to the inside of the rotating sleeve 3 in a front-to-back symmetrical manner. 54 are meshed with the adjacent toothed ring 53, a lifting block 56 is slidably connected to the upper part of the grip 1, a pull rope 55 is wound around the winding wheel 52, and the free end of the pull rope 55 is connected to the lifting block 56. When the lifting block 56 moves downward, the pull rope 55 pulls the winding wheel 52 to rotate, driving the gear 54 to rotate, thereby driving the toothed ring 53 and the rotating sleeve 3 to rotate, so that the percussion mode can be changed. A compression spring 57 is connected between the lifting block 56 and the grip 1, and a handle 58 is rotatably connected to the lifting block 56.

[0029] like Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the positioning mechanism 6 includes a positioning block 61, a clamping block 62, a sliding block 63 and a connecting spring 64. A plurality of positioning blocks 61 are fixedly connected at circumferentially uniform intervals on both sides of the front and rear of the rotating sleeve 3. The middle part of the connecting member 2 is symmetrically slidably connected to the clamping block 62, and the lower part of the connecting member 2 is symmetrically slidably connected to the front and rear. A connecting spring 64 is connected between the clamping block 62 and the adjacent sliding block 63. A groove matching the positioning block 61 is formed on the top of the clamping block 62. The clamping block 62 clamps one of the positioning blocks 61 on the same side, so as to position the positioning block 61 and thus position the rotating sleeve 3.

[0030] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the control mechanism 7 includes a sliding frame 71, a guide rod 72, a return spring 73, a protrusion 74 and a torsion spring 75. The torsion spring 75 is symmetrically connected between the handle 58 and the lifting block 56. The guide rod 72 is symmetrically fixed to the lower part of the connecting member 2. The sliding frame 71 is slidably connected to the guide rod 72. The side of the sliding frame 71 close to the adjacent protrusion 74 is an inclined surface. The upper part of the sliding frame 71 is opened with a guide hole 76. The guide hole 76 is inclined. The sliding block 63 They all move in adjacent guide holes 76, and a return spring 73 is connected between the sliding frame 71 and the adjacent guide rod 72. The upper part of the handle 58 is symmetrically fixed with protrusions 74, and the protrusions 74 abut against the adjacent sliding frames 71. When the protrusions 74 are separated from the sliding frame 71, the sliding frame 71 can move to the left under the action of the return spring 73, and the sliding block 63, the clamping block 62 and the connecting spring 64 move downward under the action of the guide hole 76, thereby releasing the positioning of the rotating sleeve 3.

[0031] Initially, the return spring 73 is in a stretched state, and the clamping block 62 clamps one of the positioning blocks 61 on the same side, so as to position the positioning block 61 and the rotating sleeve 3. The triangular Taylor knocker 4 is triangular, the end of the pointed knocker 41 is pointed, and the end of the Buck hammer 43 is a curved surface. The triangular Taylor knocker 4, the pointed knocker 41 and the Buck hammer 43 have different bearing areas and forces when knocking, so as to facilitate knocking different parts of the patient, and can induce stretch reflex, knee jerk reflex and plantar reflex. The needle wheel 42 has sharp thorns evenly spaced. When the needle wheel 42 rolls on the patient's skin surface, it can test nerve reflexes and sensitivity and check the patient's The feeling plane makes the device have a variety of different knocking modes. When the knocking mode needs to be changed, the handle 58 is manually pulled downward and rotated clockwise, driving the protrusion 74 to rotate clockwise, and the torsion spring 75 is deformed. When the protrusion 74 is separated from the sliding frame 71, the return spring 73 returns to its original state, driving the sliding frame 71 to move to the right. Under the guidance of the guide hole 76, the sliding block 63 can move downward, driving the clamping block 62 and the connecting spring 64 to move downward, so that the clamping block 62 is separated from the positioning block 61, thereby releasing the positioning of the positioning block 61 and the rotating sleeve 3, and then pulling the handle 58 downward to compress the The spring 57 is compressed, and the handle 58 can pull the pull rope 55, driving the winding wheel 52 to rotate counterclockwise, and the spiral spring 59 is deformed, thereby driving the gear 54 to rotate counterclockwise. Under the action of meshing, the gear ring 53 can rotate 90 degrees counterclockwise, driving the rotating sleeve 3 to rotate 90 degrees counterclockwise, thereby driving the triangular Taylor knocker 4, the pointed knocker 41, the needle wheel 42 and the buck hammer 43 to rotate 90 degrees counterclockwise. The percussion mode is changed every time the rotating sleeve 3 rotates 90 degrees counterclockwise, so that the percussion mode is quickly changed, which is convenient to use. When the handle 58 is released, the compression spring 57 returns to its original state, driving the handle 58 and The projection 74 moves upward to reset, causing the handle 58 to release the pull rope 55, and the torsion spring 75 returns to its original state, driving the winding wheel 52 to rotate clockwise to reset, so that the pull rope 55 can be reeled in. At this time, the rotation of the winding wheel 52 will not drive the gear 54 to rotate. When the projection 74 contacts the sliding frame 71, the projection 74 will squeeze the sliding frame 71 to move to the left, and the return spring 73 will stretch. Under the action of the guide hole 76, the sliding block 63 can move upward, driving the connecting spring 64 and the card block 62 to move upward, so that the card block 62 is stuck on the positioning projection 74, thereby being able to position the positioning projection 74 and the rotating sleeve 3, which is convenient to use.

[0032] Embodiment 2: Based on embodiment 1, Figure 2 and Figure 8As shown, it also includes a protection mechanism 8, which includes a guide frame 81, a moving block 82, a telescopic rod 83 and an arc-shaped silicone block 84. Two symmetrically arranged guide frames 81 are fixedly connected to the rotating sleeve 3, and the guide frames 81 are slidably connected to the moving blocks 82, and the moving blocks 82 are fixedly connected to the telescopic rods 83. An arc-shaped silicone block 84 is connected between the two telescopic rods 83. When the rotating sleeve 3 rotates, the guide frame 81, the moving block 82, the telescopic rod 83 and the arc-shaped silicone block 84 are driven to rotate. When the needle wheel 42 is not needed, the arc-shaped silicone block 84 is manually pulled to move to the side away from the rotating sleeve 3, so that the telescopic rod 83 is extended, and then the arc-shaped silicone block 84 is pulled backward so that the arc-shaped silicone block 84 is sleeved on the outside of the needle wheel 42. The arc-shaped silicone block 84 is made of a soft material, which can prevent people from touching the sharp part of the needle wheel 42, thereby improving the protection.

[0033] like Figure 4 As shown, it also includes a wire barrel 201. The wire barrel 201 is symmetrically fixed to the lower part of the connecting member 2. The pull rope 55 slides through the adjacent wire barrel 201. The wire barrel 201 is sleeved on the pull rope 55, which can prevent people from accidentally touching the pull rope 55 during use, and is easy to use.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
