     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     Hereinafter, the embodiments of the present disclosure will be described in detail. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present disclosure, but should not be construed as a limitation to the present disclosure. 
     Please refer to  FIGS. 1-3 . A percussive massage device F includes a massage head  1 , a base  2 , a motor  3 , an eccentric wheel  4 , an eccentric bracket  5 , a movable member  6 , an elastically deformable guider  7 , a fixing sleeve tube  8 , a head cover  9 , a rubber guide ring  10 , a rubber press ring  11 , a housing  12 , a PCB circuit board  13 , a guide aperture  14 , a rotation button casing  15 , a upper housing  16 , a lower housing  17  and silicone gloves  18 , etc. The massage head  1  and the base  2  are fixedly connected. The outer wall of the front portion of the base  2  expands outward to form a protruding ring  21 . The front end surface of the rubber guide ring  10  described below is snapped on the protruding ring  21 . When the base  2 , the massage head  1  and the movable member  6  are moving horizontally, the rubber guide ring  10  will be snapped between the fixing sleeve tube  8  and the protruding ring  21  described below, restricting its further forward movement, which plays a limit effect. 
     Please refer to  FIG. 2-3 , the base  2 , the guider  7  and the movable member  6  are arranged from the front to the back in sequence and are fixedly connected in order, and the motor  3 , the eccentric wheel  4  and the eccentric bracket  5  are linked and arranged in sequence; the movable member  6  includes a supporting haft  61 , a connecting shaft  62 , a shading plate  63  and a bottom plate  64 . The supporting shaft  61  is erected at one end of the bottom plate  64 , and the shading plate  63  is integrally connected between the other end of the bottom plate  64  and the connecting shaft  62 . The front end of the eccentric bracket  5  is provided with a first mounting hole  51 , and the supporting shaft  61  penetrates into the first mounting hole  51  through a first bearing  19 . The connecting shaft  62  penetrates through the center of the guider and penetrates into the rear end of the fixing sleeve tube  8 . A baffle plate  81  is provided at the inner rear end of the fixing sleeve tube  8 . The rear end of the base  2  is a closed end, and the inside thereof is a hollow structure. The rear end of the base  2  is inserted into the fixing sleeve tube  8 , and a fastener  30  penetrates through the closed end of the base  2 , the baffle plate  81  of the fixing sleeve tube  8 , and the connecting shaft  62  in sequence from the front to the back to realize a fixed connection of the base  2 , the fixing sleeve tube  8  and the connecting shaft  62 . The rear end of the eccentric bracket  5  is provided with a second mounting hole  52 , and the eccentric wheel  4  penetrates into the second mounting hole  52  through a second bearing  20 . The motor drives the eccentric wheel at a rotation setting. 
     Please refer to  FIG. 2  and  FIG. 6 , the guider  7  includes a guide ring  71  and a mounting ring  72  provided from the front to the rear, and the shading plate  63  abuts and covers the rear end surface of the mounting ring. The guide ring  71  and the mounting ring  72  are concentric circles, and a plurality of elastically deformable elastic ribs  73  are provided between the guide ring  71  and the mounting ring  72 . The elastic ribs  73  are curved ribs that are bent upward, and the process is simple. In the arrangement of the shading plate  63 , when the base  2 , the massage head  1 , and the fixing sleeve tube  8  are moved backward in horizontal for a certain displacement, the rear end surface of the guider  7  will be snapped on the shading plate  63 , restricting its further backward movement, which plays a limit function. At the same time, the guider  7  is elastically deformed under the pressing of the shading plate  63 . The material of the guider  7  is a TPEE (thermoplastic polyester elastomer), a block copolymer containing a polyester hard segment and a polyether soft segment. This material makes the elastic deformation of the guider  7  better. When the guider  7  is pressed forward, the elastic ribs  73  are elastically deformed backward. When the guider  7  is pulled backward, the elastic ribs  73  are elastically deformed forward. The design of the guider  7  does not require high precision, thereby the cost is effective saved. 
     Please refer to  FIG. 2  and  FIG. 7 , the front end surface of the head cover  9  is an opening structure, and the front end surface of the head cover  9  is provided with a folded edge  91  that is bent inwardly at the opening structure. The rear end portion of the rubber guide ring  10  is formed with a groove  101  and a convex edge  102 . The front end portion of the rubber guide ring  10  penetrates out of the front end surface of the head cover  9  from the back to the front, and the folded edge  91  is inserted into the groove  101  and buckled with the convex edge  102 . The rubber press ring  11  is provided behind the rubber guide ring  10 , and the head cover  9 , the rubber guide ring  10  and the rubber press ring  11  are fixedly connected. The head cover  9  is fixedly connected to the housing  12 , and the head cover  9 , the rubber guide ring  10 , the rubber press ring  11 , and the housing  12  are sleeved on the fixing sleeve tube  8 . When the base  2 , the massage head  1 , and the fixing sleeve tube  8  and the movable member  6  are moved forward and backward horizontally for a certain displacement, the rubber guide ring  10  will also generate elastic deformation, so that the massage head  1  can better perform tap massage on the human body. 
     Please refer to  FIGS. 3-5 , when the present disclosure is used, the motor  3  drives the eccentric wheel  4  and the eccentric bracket  5  to rotate, and the eccentric bracket  5  outputs fast eccentric rotation. Because the supporting shaft  61  of the movable member  6  penetrates into the first mounting hole  51  of the eccentric bracket  5 , the movable member  6  will be pulled or pushed horizontally forward or backward when the eccentric bracket  5  rotates fast, so that the base  2 , the massage head  1  and the fixing sleeve tube  8  are moved horizontally forward or backward. At the same time, the guider  7  and the rubber guide ring  10  are elastically deformed forward or backward, so that the human body can be quickly and gently massaged by tapping. 
     Herein, only preferred embodiments of the disclosure are described, and the scope to be claimed cannot be limited thereto. Thus, any equivalent change to the embodiments still falls within in the scope covered by the claims.
