In this embodiment, the reducer is provided with four intermediate shafts between the input shaft 30 and the output shaft 31, and after multi-stage reduction, the speed ratio of the input shaft 30 and the output shaft 31 is 20:1.

[0034] like Figure 5 As shown, a driving motor, a control chip and a power supply (not shown in the figure) are provided in the remote control 1. A rotating shaft 11 and a switch 12 are provided on the remote control 1. One end of the rotating shaft 11 is fixedly connected to the second magnetic component 5, and the other end of the rotating shaft 11 is fixedly connected to the output shaft of the driving motor. The power supply and the control chip are both electrically connected to the switch 12, and the control chip is electrically connected to the driving motor. When the switch 12 is pressed to obtain power, the control chip controls the driving motor to start after receiving the signal from the switch 12. When the output shaft of the driving motor rotates, the rotating shaft 11 and the second magnetic component 5 fixedly connected thereto are driven to rotate synchronously. Among them, the remote control 1 uses mature products sold on the market, and only the rotating shaft 11 and the second magnetic component 5 are fixedly connected to the output shaft of the driving motor. Therefore, its specific structure and control principle are not repeated here.

[0035] like Figure 2As shown, the first magnetic component 4 and the second magnetic component 5 are arranged correspondingly, and the structures of the first magnetic component 4 and the second magnetic component 5 are the same, both of which include an insulating cover 41, and two magnets 42 are fixedly arranged in the insulating cover 41, and the polarities of the two magnets 42 are opposite. Preferably, the insulating cover 41 is made of elastic hard plastic material, and the shape of the insulating cover 41 can be rectangular, square, circular or other shapes, and can be designed according to actual needs, and is not limited here. The corresponding inner wall at the opening of the insulating cover 41 is symmetrically provided with a limiting protrusion 411, and the limiting protrusion 411 abuts against the two magnets 42 to prevent the two magnets 42 from falling from the inside of the insulating cover 41. A rectangular notch 412 is opened on the outer side and bottom surface of the insulating cover 41, and the position of the notch 412 corresponds to the position of the two magnets 42, and the two magnets 42 are both located in the notch 412, so that a part of the two magnets 42 is located outside the insulating cover 41.

[0036] When the underwear tightness adjustment mechanism of the utility model is used, one of the magnets (not shown in the figure) of the second magnetic component 5 is brought close to one of the magnets 42 of the first magnetic component 4. When the remote controller 1 controls the second magnetic component 5 to rotate, due to the effect of the magnetic field, the first magnetic component 4 and the second magnetic component 5 rotate synchronously in the same direction or synchronously in the opposite direction. When another magnet (not shown in the figure) of the second magnetic component 5 is brought close to the magnet 42 of the first magnetic component 4, when the second magnetic component 5 rotates, due to the effect of the magnetic field, the rotation direction of the first magnetic component 4 is opposite to the previous rotation direction. Therefore, by changing the relative positions of the two magnets 42 in the second magnetic component 5 and the first magnetic component 4, the second magnetic component 5 drives the first magnetic component 4 to rotate synchronously in the same direction or synchronously in the opposite direction when rotating, and the rotation of the first magnetic component 4 drives the output shaft 31 in the micro reducer 3 to rotate clockwise or counterclockwise.

[0037] The utility model also provides an underwear, such as Figure 1As shown, the underwear includes an underwear body 6 and an underwear elastic adjustment mechanism, and the underwear elastic adjustment structure is detachably connected to the underwear body 6. The underwear body 6 includes a first underwear body 61 and a second underwear body 62, and the first underwear body 61 and the second underwear body 62 together enclose a wearing space. The front sides of the first underwear body 61 and the second underwear body 62 are connected by a drawstring 63. In this embodiment, the front sides of the first underwear body 61 and the second underwear body 62 are both provided with a drawstring hole. One end of the drawstring 63 is fixed to the front side of the second underwear body 62, and the other end crosses and passes through a plurality of drawstring holes to connect the front sides of the first underwear body 61 and the second underwear body 62. The rear sides of the first underwear body 61 and the second underwear body 62 are connected by a buckle structure (not shown in the figure). In this embodiment, the buckle structure can be connected in a buckle ring and a buckle hook. The buckle ring and the buckle hook are existing technologies and will not be repeated here. The buckle ring and the buckle hook are respectively arranged on the first underwear body 61 and the second underwear body 62, so as to connect and open the first underwear body 61 and the second underwear body 62 by fastening and disengaging the buckle ring and the buckle hook. In this embodiment, the fastening structure can also be in other forms such as buttons, zippers or Velcro, which are not limited here.

[0038] like Figure 2 As shown, the free end of the pull rope 63 is fixed with a connecting sleeve 64, and the connecting sleeve 64 is sleeved on the outside of the output shaft 31. The output end of the output shaft 31 has a flat notch, and a blind hole (not shown in the figure) is provided in the connecting sleeve 64 for the output end of the output shaft 31 to be inserted. The shape of the blind hole is the same as the shape of the output shaft 31 with the flat notch, which is slightly D-shaped and the size of the blind hole is slightly smaller than the size of the output end of the output shaft 31. The connecting sleeve 64 is made of a plastic material with a certain elasticity so that the connecting sleeve 64 and the output shaft 31 are closely matched, and the matching arrangement of the flat notch and the D-shaped blind hole plays a role of limiting and guiding, preventing the connecting sleeve 64 from rotating on the output shaft 31.

[0039] Two female buckles (not shown) are fixed on the front side of the first underwear body 61, and two sub-buckles 21 are arranged on the outer side of the shell 2. The sub-buckles 21 and the female buckles are correspondingly buckled. The sub-buckles 21 and the female buckles are matched to facilitate the detachable connection between the shell 2 and the underwear body 6. The shell 2 and the underwear body 6 can also be connected in other ways, as long as they are easy to load and unload, and there is no limitation here.

[0040] When the underwear of the utility model is used in daily life, the deceleration device is installed on the underwear body 6, and the connecting sleeve 64 on the drawstring 63 is sleeved on the output shaft 31. When the underwear needs to be adjusted, the second magnetic component 5 of the remote controller 1 is close to the first magnetic component 4, and the switch 12 is pressed, the driving motor starts to drive the second magnetic component 5 to rotate, and then the first magnetic component 4 is driven to rotate in the same direction or in the opposite direction through the magnetic field, and the drawstring 63 is driven to be wound on the output shaft 31 and tightened or loosened after being decelerated by the micro reducer 3. When the underwear needs to be washed, the sub-button 21 and the mother buckle are unfastened so that the sub-button 21 and the mother buckle are no longer buckled, and the deceleration device is removed from the underwear body 6 to wash the underwear normally. Embodiment 2

[0041] On the basis of the first embodiment, the present utility model only proposes another solution for the remote control 1 and the second magnetic component 5. Two switches 12 are provided on the remote control 1 (only one switch is shown in the figure), wherein one switch 12 controls the drive motor to rotate clockwise, and the other switch 12 controls the drive motor to rotate counterclockwise. Only one magnet 42 is provided on the second magnetic component 5. When it is necessary to rotate the first magnetic component 4, the magnet 42 on the remote control 1 is brought close to the magnet 42 on the reduction device, and one of the switches 12 is pressed, and the drive motor starts to drive the second magnetic component 5 and the first magnetic component 4 to rotate synchronously. If it is necessary for the first magnetic component 4 to rotate in the opposite direction, the other switch 12 is pressed, and the drive motor starts to drive the second magnetic component 5 and the first magnetic component 4 to rotate in the opposite direction synchronously, thereby realizing that the first magnetic component 4 drives the output shaft 31 on the micro reducer 3 to rotate clockwise or counterclockwise.

[0042] Although the present invention discloses a preferred specific embodiment to achieve the above-mentioned purpose, it is not intended to limit the structural features of the present invention. Any person skilled in the art should know that under the technical spirit of the present invention, any easily conceivable changes or modifications are possible and are all covered by the scope of the patent application of the present invention.
