[0021] As shown in the figure, the utility model discloses a high-stability percussion massager, which has an outer shell 2, in which a driving motor 6 is arranged, and the driving motor 6 drives the percussion arm 7 to reciprocate through a transmission assembly. Specifically, the transmission assembly includes a circular transmission block 16, and the output shaft of the driving motor 6 is eccentrically connected to the circular transmission block 16. A transmission sleeve 15 is mounted on the outside of the circular transmission block 16, and a transmission handle 18 extends from one end of the transmission sleeve 15. The transmission handle 18 is hinged to one end of the percussion arm 7. A guide seat 5 is fixedly arranged in the outer shell 2, and the percussion arm 7 passes through the guide seat 5. Furthermore, the guide seat 5 is made of elastic material, and a guide sleeve 23 is arranged in the guide seat 5. The guide sleeve 23 has a guide groove for the percussion arm 7 to pass through. During the high-speed reciprocating movement of the percussion arm 7, the guide seat 5 made of elastic material can buffer the vibration generated by the entire percussion component, effectively reduce the vibration of the outer shell during use, and thus enhance the user experience. By controlling the driving motor 6 to drive the circular transmission block 16 to move, and through the transmission sleeve 15, the knocking arm 7 can be driven to reciprocate under the guidance of the guide seat 5. Furthermore, the driving motor 6 is a double-headed motor, and the transmission assembly, the knocking arm 7, and the massage head frame 4 are correspondingly provided with two groups. The side wall of the output shaft 17 at one end of the driving motor 6 is extended with a transmission pin 19, and the circular transmission block 16 is provided with an arc groove 20 for the transmission pin 19 to move. The transmission pin 19 can squeeze the end faces 21 on both sides of the arc groove 20 to drive the circular transmission block 16 to move. By controlling the driving motor 6 to drive the output shaft 17 to rotate, when the end face 21 that the transmission pin 19 on the output shaft 17 at one end has already contacted happens to be the extrusion direction of the rotation of the output shaft 17, the transmission pin on the output shaft 17 will immediately drive the circular transmission block 16 to move, and at the same time, the output shaft at the other end will also immediately drive the output shaft 17 with the end face 21 that is in contact with the output shaft 17. The eccentrically connected circular transmission block moves to realize the synchronous movement of the two knocking arms for knocking massage. When the end face that the transmission pin 19 on the output shaft 17 at one end contacts is not in the direction of the output shaft 17's movement, the output shaft 17 will first drive the transmission pin 19 to swing in the arc groove 20 when rotating until it squeezes the end face on the other side and then drives the circular transmission block to move. The output shaft 17 at the other end will still immediately drive the circular transmission block eccentrically connected to it to move, thereby realizing the asynchronous movement of the two knocking arms. By adopting this structure, by controlling the forward and reverse rotation of the drive motor 6, the synchronous knocking massage and the asynchronous knocking massage of the massage heads on both sides can be switched, thereby enriching the massage methods and improving the user experience. It also includes a massage head frame 4. In this embodiment, two massage heads 3 are arranged on the massage head frame 4. By selecting and plugging in the massage head frame 4 with different numbers of massage heads, switching between single-point percussion massage and multi-point percussion massage can be achieved. A connecting portion 13 is extended on the massage head frame 4, and the connecting portion 13 can be inserted into the connecting hole 22 on the percussion arm 7. The percussion arm 7 is circumferentially provided with a positioning groove 8 on the inner side wall at the top of the connecting hole 22, and a positioning block 14 that can be inserted into the positioning groove 8 is provided on the connecting portion 13.Furthermore, one end of the connection part 13 has an elastic connection head 12. When the connection part 13 is inserted into the connection hole 22, the connection head 12 is tightened in the connection hole 22 to prevent the massage head frame 4 from slipping out after being inserted into the connection hole 22. The outer side of the connection part 13 is sleeved with a connection sleeve 10 made of elastic material. The connection sleeve 10 is provided with a clearance groove 11 for the positioning block 14 to pass through. The outer side of the connection sleeve 10 is extended with an annular convex ring 9, which is tightly pressed in the connection hole 22, so that the massage head frame can be more firmly inserted in the connection hole 22. The two ends of the outer shell 2 are provided with a connection plate 1, and the connection plate 1 is provided with a connection groove, which is connected to the elastic band. By tying the elastic band to the corresponding position where massage is required, the positioning of the entire device can be easily achieved, and there is no need to hold the device, which is more flexible and convenient to use.

[0022] The high-stability percussion massager of the utility model provides a positioning block 14 on the connecting portion 13 of the massage head frame 4, and provides a positioning groove 8 for inserting the positioning block 14 on the hammer arm 7, so that when the massage head frame 4 is inserted into the connecting hole 22 on the hammer arm 7, the positioning block 14 cooperates with the positioning groove 8 to realize rotation locking of the massage head frame 4. At the same time, by selecting the positioning grooves 8 at different positions to cooperate with the positioning block 14, the locking angle of the massage head frame 4 can be selected to prevent the massage head frame 4 from rotating during operation, thereby ensuring the stability of the position of the massage head 3, effectively improving its massage effect, and providing a better massage experience.
