However, current technology typically uses a single electric hammer mechanism connected to a single massage roller for targeted tapping, resulting in noticeable noise from the massage device. Furthermore, the electric hammer mechanism occupies a significant amount of space in the massage device, affecting comfort. Utility Model Content

[0017] Example: As attached Figures 1-4 The illustrated hammer mechanism includes an upper housing 1 and a lower housing 2. A hammering module 3 is installed inside the lower housing 2. The hammering module 3 includes two symmetrically arranged hammering mechanisms 4 and several massage heads 8 formed with the hammering mechanisms 4 (each hammering mechanism 4 connects to two transmission supports 14, and each of the two transmission supports 14 has 2 to 4 massage heads 8). Transmission components 9 and eccentric components 10 connected to the transmission components 9 are provided on the output ends of both sides of the hammering mechanisms 4. The eccentric components 10 include two symmetrically arranged eccentric bushings 11 (inserted together) and a limiting sleeve 12 (specifically, in an eccentric state). The limiting sleeve 12 rotates... The eccentric bushing 11 is clamped to the outer circumference of the limiting sleeve 12 and clamps one end of the transmission component 9. The massage head 8 (specifically made of rubber) is installed on both ends of the transmission component 9. The two output ends of the hammering core 4 are respectively provided with a first positioning ring 28, a screw sleeve 29 and a second positioning ring 30, which form a transmission connection with the eccentric bushing 11. The transmission bracket 14 transmits the power of the eccentric bushing 11 to the massage heads 8 at both ends in sequence, so that a single hammering core 4 can control four massage heads 8 to perform massage and hammering through the transmission bracket 14, which solves the problems of high noise, complex structure and poor massage comfort of massage equipment.
[0018] As attached Figure 3 As shown, the transmission assembly 9 includes a rolling bearing 13 and a transmission bracket 14. The rolling bearing 13 is clamped between two eccentric bushings 11. The transmission bracket 14 is provided with a first L-shaped support 15, a mounting sleeve 16, and a second L-shaped support 17 (specifically, an integral structure). The mounting sleeve 16 is sleeved on the outer circumferential surface of the rolling bearing 13. One end of the first L-shaped support 15 is connected to the mounting sleeve 16, and the other end extends toward the other side. One end of the second L-shaped support 17 is connected to the mounting sleeve 16, and the other end extends toward the side away from the first L-shaped support 15. The transmission bracket 14 uses the rolling bearing 13 to realize power transmission and transmits the power to the massage head 8 at the end.
[0019] As attached Figure 3 As shown, the first L-shaped support 15 is provided with a first reinforcing rib 18 (specifically an integral structure), and the second L-shaped support 17 is provided with a second reinforcing rib 19 (specifically an integral structure), which improves the structural robustness of the transmission bracket 14 and ensures the stability of the transmission force during the transmission process.
[0020] As attached Figure 3As shown, a first positioning sleeve 20 is fixedly installed on the first L-shaped support 15, and a second positioning sleeve 21 is fixedly installed on the second L-shaped support 17. The first positioning sleeve 20 and the second positioning sleeve 21 are respectively provided with a first mounting through hole 23 and a second mounting through hole 24 for installing massage heads 8. The plurality of massage heads 8 are provided with a plug-in part 25 (specifically an integral structure) for plugging into the first positioning sleeve 20 and the second positioning sleeve 21 to achieve a stable connection of the massage heads 8 and prevent the massage heads 8 from falling off.
[0021] As attached Figure 3 As shown, a first supporting slope 26 (specifically an integral structure) is provided at the connection between the first positioning sleeve 20 and the first L-shaped support part 15, and a second supporting slope 27 (specifically an integral structure) is provided at the connection between the second positioning sleeve 21 and the second L-shaped support part 17, which improves the structural stability of the connection and prevents breakage during use.
[0022] As attached Figure 4 As shown, the hammering core 4 is provided with a first positioning ring 28 and a second positioning ring 30 in sequence. The first positioning ring 28 and the second positioning ring 30 clamp the limiting sleeve 12 and are installed in the eccentric bushing 11. The first positioning ring 28 and the second positioning ring 30 realize the positioning function, and the limiting sleeve 12 increases the clamping force when installed with the eccentric bushing 11.
