[0020] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0021] like Figures 1 to 4 As shown, a toggle-type gripper massage device comprises a shell 1, a plurality of mounting bases 2 movably mounted on the shell 1, a massage head 3 detachably mounted on the mounting base 2, and a relaxation drive mechanism for driving the mounting base 2 to move closer and farther away at the same time, wherein the relaxation drive mechanism comprises a rotating shaft 11 fixed on the top of the shell 1, a relaxation drive wheel 12 movably mounted in the shell 1, and a motor 13 transmission-connected to the relaxation drive wheel 12 via a reduction wheel set, a driving arm 14 deviating from the central axis of rotation is provided on the upper side surface of the relaxation drive wheel 12, a middle portion of the mounting base 2 is sleeved on the rotating shaft 11, a long groove 21 for accommodating the upper end portion of the driving arm 14 is provided at the lower portion of the mounting base 2, and the long groove 21 on the mounting base 2 is parallel to the rotating shaft 11 on the mounting base 2.

[0022] During the operation of the gripper massage device, the expansion drive wheel 12 rotates continuously under the action of the motor 13 and the reduction wheel group to drive the drive arm 14 to perform uniform circular motion around the rotation center of the current expansion drive wheel 12. Since the upper end of the drive arm 14 is movably sleeved in the long groove 21, the drive arm 14 drives the lower part of the mounting base 2 to perform radial reciprocating swings during the circular motion, thereby realizing radial reciprocating motion of the upper end of the mounting base 2 and the massage head 3. When multiple mounting bases 2 are arranged axially, multiple massage heads 3 simultaneously move toward the middle or expand outward at the same time, thereby realizing the massage device simulating the grasping and pinching massage effect of human hands, and the comfort is high. The massage device of the utility model does not have complex structures or difficult to process special-shaped parts that are difficult to injection mold. The parts have simple structures, low manufacturing costs, and greatly reduce the difficulty of assembly. The overall cost is significantly reduced, and the cost performance is higher.

[0023] In this embodiment, the number of the rotating shafts 11 is equal to and corresponds to the number of the mounting bases 2. The number of the mounting bases 2 and the number of the massage heads 3 are both four. The four rotating shafts 11 are radially evenly distributed above the housing 1. Specifically, the multiple rotating shafts 11 are on the same circumference, and the rotating shafts 11 are tangent to the circumference. The four massage heads 3 move toward and away from the center at the same time, and the grasping and kneading massage effect is closer to the grasping and kneading massage effect of human hands, which basically achieves the effect of simulating or even replacing manual massage, and is highly practical.

[0024] In this embodiment, a plurality of vertical plates 15 are provided on the upper side of the shell 1, and both ends of the rotating shaft 11 are fixedly connected to the upper ends of the vertical plates 15. The mounting base 2 reciprocates around the rotating shaft 11 during the swinging process, and the structure has higher stability, better durability, and longer service life.

[0025] In this embodiment, the upper end of the driving arm 14 is provided with a linkage ball 16 whose diameter is larger than that of the driving arm 14. The linkage ball 16 is movably embedded in the long groove 21. The design of the linkage ball 16 effectively solves the interference problem between the middle section of the driving arm 14 and the opening edge of the long groove 21, thereby avoiding jamming between the driving arm 14 and the long groove 21, and the driving stability and reliability are relatively high.

[0026] In this embodiment, a socket hole 31 is provided at the inner end of the massage head 3, and a detachable connector 22 is provided on the upper part of the mounting base 2 and is connected to the socket hole 31 by interference fit, so as to facilitate the disassembly and replacement of the massage head 3. The massage head 3 can also be disassembled and cleaned, which is convenient for cleaning and more practical.

[0027] In this embodiment, the reduction gear set includes a worm 17 fixedly mounted on the main shaft of the motor 13, a worm wheel 18 meshing with the worm 17, and a plurality of reduction gears. The diastolic driving wheel 12 is connected to the worm wheel 18 through a plurality of reduction gears.

[0028] In this embodiment, the outer wall of the motor 13 is equipped with a soft heat-conducting sleeve 19. The design of the soft heat-conducting sleeve 19 reduces the resonance noise between the motor 13 and the housing 1, and also improves the heat dissipation effect of the motor 13, thereby further improving the reliability and service life.
