[0023] Reference Figures 1 to 6 A handheld massage gun comprises a straight shell 3, which is in the shape of a cylinder with openings at both ends; a massage head 2 is installed at one end of the shell 3, which can be equipped with a plurality of massage heads of different shapes, which can be detached and replaced and are suitable for different parts of the human body, and a control surface cover 4 is installed at the other end; a power mechanism for driving the massage head 2 is installed in the shell 3, and the control surface cover 4 is electrically connected to the power mechanism. The straight cylindrical gun body can reduce the overall occupied space, and is more convenient to carry and store than existing massage guns.

[0024] The power mechanism includes a motor 1, the axis of the motor 1 is parallel to the axis of the shell 3, and the motor 1 and the shell 3 are installed parallel to each other to fully utilize the space in the motor cavity 6, and a high-power motor can be used. At the same time, it also fits the tubular structure of the shell, which can reduce the volume of the massage gun while maintaining a large output power.

[0025] A fixing bracket 5 is detachably installed in the shell 3, and the motor 1 is installed on the fixing bracket 5. Various components in the massage gun can be installed on the fixing bracket 5, and then the fixing bracket assembly is installed in the shell together. Compared with the existing assembly method, the assembly is simple and quick, which greatly improves the production efficiency.

[0026] A motor cavity 6 is provided at one end of the fixed bracket 5 close to the control surface cover 4, and a sliding groove 7 is provided at the other end of the fixed bracket 5. A transmission cavity 8 is provided between the motor cavity 6 and the sliding groove 7. The motor 1 is installed in the motor cavity 6. A plurality of cavities are provided on the fixed bracket, and then various components are regularly and orderly installed in each cavity. Compared with the existing assembly method, the components are more compact, which can further reduce the overall space occupied by the massage gun.

[0027] A transmission rod 9 is slidably connected in the sliding groove 7, and a mounting column 10 is provided at one end of the transmission rod 9. The massage head 2 is installed on the mounting column 10, and a roller 11 is rotatably connected to the bottom of the other end. A rotating shaft 12 is provided at the bottom of the transmission cavity 8, and a first bevel gear 13 is rotatably connected to the rotating shaft 12. A second bevel gear 21 is installed on the rotating shaft of the motor 1. After assembly, the first bevel gear 13 is meshed with the second bevel gear 21. An eccentric cavity 14 is provided on the top of the first bevel gear 13. The roller 11 is installed in the eccentric cavity 14. The first bevel gear 13 is rotated by the motor 1, so that the eccentric cavity 14 drives the roller 11 to perform eccentric movement, thereby driving the transmission rod 9 to telescopically slide in the sliding groove 7. The structure is simple and reliable.

[0028] The transmission rod 9 is provided with a through slot 15, and a first spring bracket 16 is provided at one end of the through slot 15 close to the mounting column 10, and a second spring bracket 17 is provided at the other end of the sliding slot 7 corresponding to the through slot 15, and a buffer spring 18 is installed between the first spring bracket 16 and the second spring bracket 17, and the diameter of the roller 11 is smaller than the diameter of the eccentric cavity 14, and a buffer spring 18 is installed between the transmission rod 9 and the sliding slot 7, and the roller 11 is always pressed into the eccentric cavity 14 by the elastic force of the buffer spring 18. The inner wall of the eccentric cavity 14 is provided with a relative movable space because the diameter of the roller 11 is smaller than the diameter of the eccentric cavity 14. When the motor 1 rotates the first bevel gear 13, the roller 11 rolls along the inner wall of the eccentric cavity 14 under the elastic force of the buffer spring 18, driving the transmission rod 9 to slide and retract in the sliding groove 7. The buffer spring 18 is used to replace the traditional push rod straight push type massage gun, which has a good buffering effect while ensuring its massage function, thereby preventing the user from using too much force when using it and excessively pressing the massage gun on the muscle to cause severe pain.

[0029] A rolling bearing 22 is installed between the rotating shaft 12 and the first bevel gear 13 to reduce the friction between the rotating shaft 12 and the first bevel gear 13 and reduce the power loss of the motor.

[0030] Sliding grooves 19 are provided on both sides of the transmission rod 9, and guide rails 20 are slidably connected in the sliding grooves 19. The guide rails 20 are fixed on both sides of the sliding grooves 7. The transmission rod 9 is fixed in the sliding grooves 7 through the guide rails 20 and relative sliding occurs. The structure is simple and reliable.

[0031] A support plate 23 is provided on the top of the transmission cavity 8, and a battery 24 is installed on the support plate 23. The battery 24 is electrically connected to the control surface cover 4, which makes full use of the internal space of the shell 3, makes the parts more compact, and can further reduce the overall space occupied by the massage gun.

[0032] The control surface cover 4 is provided with an illumination light source, and the control surface cover 4 can provide an illumination function, so that the massage gun has a wider range of uses.

[0033] The above implementation modes cannot limit the protection scope of the present invention. The equivalent modifications and changes made by those skilled in the art without departing from the overall concept of the present invention are still within the scope of the present invention.
