[0017] Working Example:

[0018] As shown in Figures 1-6, The present invention provides a novel massage gun including a housing 1 with kneading balls 2 attached to one end thereof, wherein a drive assembly 3 and a connection assembly 4 are attached inside the housing 1, the drive assembly 3 includes a motor 301, a fixed platen 302 fixedly attached to the output end of the motor 301, the output shaft of the motor 301 passing through the fixed platen 302 and connected to an eccentric wheel 303, the connection assembly 4 includes a linear bearing 401 and a connecting rod 404, one end of the kneading balls 2 is engaged with one end of the linear bearing 401, a fixed cylinder 402 is fitted to the outside of the linear bearing 401, one end of the connecting rod 404 is rotatably connected to the inner wall of the linear bearing 401 via an axle pin 405, and the other end of the connecting rod 404 is provided with a circular connecting groove through which the connecting rod 404 is rotatably connected to the eccentric wheel 303.

[0019] In particular, housing 1 is formed by joining housing A101 and housing B102, both of which are rectangular, with semicircular rings provided at one end of housing A101 and housing B102, and the two sets of semicircular rings are connected via a fixed ring 6, improving the connection stability of housing A101 and housing B102. Two sets of semicircular engaging portions are provided on the inside of each of housing A101 and housing B102, and the two sets of semicircular engaging portions are installed perpendicular to each other.

[0020] Among these, a silicone case 403 is fitted onto the outside of the fixed cylinder 402, and the silicone case 403 is fixedly attached to a circular attachment portion provided horizontally between the housing A101 and the housing B102.

[0021] In particular, a silica gel ring 304 is fitted to the outside of the fixed platen 302, and this silica gel ring 304 is fixedly attached to a circular attachment portion provided vertically between the housing A101 and the housing B102, thereby quickly fixing the fixed platen 302 and achieving quick fixing to the motor 301. At the same time, the installation of the silica gel ring 304 can effectively absorb vibrations generated by the motor 301 when it is operating, which is advantageous in reducing the operating noise of the entire device.

[0022] In particular, a mounting hole is provided at one end of the connecting rod 404, and rubber caps 406 are fixedly attached to both ends of the mounting hole, and the shaft pin 405 is inserted between the two sets of rubber caps 406, and the tips of the rubber caps 406 are all hemispherical, so that when the connecting rod 404 swings, wear on the shaft pin 405 is reduced, and at the same time, noise generation is further reduced, unnecessary parts are eliminated, and the assembly procedure is simplified. The linear bearing 401 is provided with two sets of through holes symmetrically, which can be connected to both ends of the shaft pin 405.

[0023] In particular, a clamp-type coupling is provided on the bottom side of eccentric wheel 303, which is connected to the output shaft of motor 301 and locked with a clamping bolt. The use of a clamp-type coupling and a clamping bolt for connection achieves the effect of clamping the shaft, ensuring stable operation, eliminating vibration, and achieving the goals of low noise. A disk is provided on the top side of eccentric wheel 303, and a bearing 407 is fitted on the outside of the disk and fixed in a circular connecting groove, which reduces friction when the disk rotates and is advantageous for high-speed, stable rotation and power transmission.

[0024] In particular, the storage battery 5 and the control main board 7 are fixed inside the housing 1, and the control main board 7 is electrically connected to the storage battery 5 and the motor 301 via conductors. A control button and a charging port are attached to one side of the control main board 7, and the housing 1 is provided with corresponding notches to expose the control button and the charging port, making it easy for users to quickly adjust and use, and providing high convenience in use.

[0025] Operating principle of this embodiment: By installing the drive assembly 3 and the connection assembly 4, the present invention effectively simplifies the components inside the housing, reducing overall manufacturing costs and facilitating quick maintenance or component replacement after a malfunction. The absence of a grip on the housing 1 effectively reduces the overall volume, making it convenient for portable use and highly portable. By attaching a silicone case 403 to the outside of the fixed cylinder 402 and a silica gel ring 304 to the outside of the fixed platen 302, vibrations generated by the drive assembly 3 and the connection assembly 4 during operation can be effectively reduced, resulting in good quietness. Furthermore, during assembly, the motor 301 and the cylinder 402 can be quickly fixed, simplifying the assembly process and improving space utilization for the housing 1, which is advantageous for downsizing the housing.
