[0024] For this specific embodiment, the wrapping strap 102 is connected to the placement rack 101, and the adhesive tape 103 is connected to the wrapping strap 102. The wrapping strap 102 is bound to the placement rack 101 by cooperating with the buckles on both sides of the placement rack 101. A corresponding bonding or fixing mechanism is provided between the wrapping strap 102 and the adhesive tape 103. The user can choose the connection between the wrapping strap 102 and the adhesive tape 103 according to actual conditions. For example, it can be directly connected by Velcro or by snap fastener. Since the connection structure between the wrapping strap 102 and the adhesive tape 103 mentioned above is a very mature existing technology, it will not be repeated in this solution.

[0025] The connecting block 104 is fixedly connected to the winding strap 102 and is located on one side of the winding strap 102. The winding post 105 is rotatably connected to the connecting block 104 and is located inside the connecting block 104.

The two rubber binding ropes 106 are fixed to the ends of the adhesive tape 103, so that when the user wears the entire wristband on the wrist through the cooperation of the adhesive tape 103 and the winding strap 102, the user can directly tighten and loosen the rubber binding rope 106 by driving the rotation of the two winding posts 105, thereby completing the rapid adjustment of the tightness of the entire strap.

[0026] Secondly, the driving gear 107 is fixedly connected to the winding column 105 and is located on one side of the winding column 105; the rotating gear 108 is meshed with the driving gear 107 and is connected to the connecting block 104 through the driving component; the driving component is connected to the rotating gear 108, and the rotating shaft 109 is fixedly connected to the rotating gear 108 and is rotatably installed on one side of the connecting block 104; the screwing cap 110 is fixedly connected to the rotating shaft 109 and is located on one side of the rotating shaft 109, the driving gear 107 is arranged one by one with the winding column 105, and the two driving gears 107 are simultaneously connected to the middle The rotating gear 108 is meshed, and the rotating gear 108 is rotatably installed inside the connecting block 104 through the rotating shaft 109. The screwing cap 110 is fixed to the outer end of the rotating shaft 109, and a corresponding arc anti-slip pad is provided on the outer side of the screwing cap 110, so that the user can directly drive the rotating shaft 109 by screwing the screwing cap 110, and then drive the rotating gear 108 to rotate through the rotation of the rotating shaft 109, so that the driving gears 107 on both sides and the winding column 105 can be rotated through the rotation of the rotating gear 108, thereby completing the winding of the rubber binding rope 106.

[0027] When the wristband with quick adjustment of tightness of the present embodiment is used, the placement frame 101 is bound to the user's wrist through the cooperation of the winding strap 102 and the adhesive tape 103, so that the user can place and hold a mobile phone or other motor device through the placement frame 101. Then, the user can drive the rotating shaft 109 by twisting the twisting cap 110 according to the actual situation, and the rotating gear 108 is driven by the rotating shaft 109 to drive the driving gear 107 and the winding column 105 on both sides, and then the two rubber binding ropes 106 are rolled up by the rotation of the winding column 105, so that the wristband as a whole is continuously tightened, and then the reverse rotation of the rotating shaft 109 is limited by the provided limiting component, so that after the wristband is tightened, the reverse rotation of the rotating shaft 109 will not hesitate to cause the rubber binding rope 106 to loosen, so that the user can quickly adjust the tightness of the wristband to a suitable range according to the actual use situation through the provided component, thereby enhancing the actual wearing experience of the user.

[0028] Second embodiment:

[0029] Based on the first embodiment, please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the overall structure of the wristband for quickly adjusting the tightness of the second embodiment. Figure 6This is a structural schematic diagram of the sleeve ratchet 201 of the second embodiment. The limiting component provided by the utility model includes a sleeve ratchet 201, a fixing frame 202, a matching frame 203 and a compression spring 204. The matching frame 203 has a connecting boss 205, a matching boss 206 and a locking boss 207.

[0030] The sleeve ratchet 201 is fixedly connected to the rotating shaft 109 and sleeved on the rotating shaft 109; the fixing frame 202 is fixedly connected to the connecting block 104 and is located on one side of the connecting block 104; the matching frame 203 is slidably connected to the fixing frame 202 and is located on a side of the fixing frame 202 close to the sleeve ratchet 201; the two sides of the extrusion spring 204 are respectively connected to the matching frame 203 and the fixing frame 202, and the connecting boss 205 is located on a side of the matching frame 203 close to the fixing frame 202; the matching boss 206 is located on one side of the matching frame 203 close to the sleeve ratchet 201; the detent boss 207 is located on one side of the matching frame 203, the sleeve ratchet 201 is fixed to the end of the rotating shaft 109, the matching frame 203 is slidably arranged at the bottom of the connecting block 104 by cooperating with the fixing frame 202, the matching boss 206 provided at the end of the matching frame 203 cooperates with the sleeve ratchet 201, the end of the matching boss 206 is provided with an inclined platform to adapt to the inclined external teeth of the sleeve ratchet 201, and the middle end of the matching frame 203 is provided with the connecting The boss 205 cooperates with the extrusion spring 204 arranged inside the fixing frame 202, and the detent boss 207 is arranged at the outer end of the matching frame 203. The detent boss 207 is provided to facilitate the user to toggle the matching frame 203. When the sleeve ratchet 201 rotates in a set direction following the rotating shaft 109, the inclined outer teeth on the outer side of the sleeve ratchet 201 will squeeze the matching boss 206 at the end of the matching frame 203, so that the matching frame 203 is slightly moved on the fixing frame 202 by the detent spring 204. When the ratchet 201 is driven by the rotating shaft 109 to rotate in the opposite direction to the set direction, the boss at the inclined outer end of the ratchet 201 will be limited by the resistance of the matching boss 206 on the matching frame 203, thereby completing the unidirectional rotation limit of the rotating shaft 109. When the user needs the rotating shaft 109 to rotate in the opposite direction, he only needs to move the matching frame 203 by turning the button boss 207, so that the matching boss 206 of the matching frame 203 is out of engagement with the inclined outer teeth of the ratchet 201.

[0031] When using a wristband for quickly adjusting the tightness of the present embodiment, the provided ratchet 201 can cooperate with the matching frame 203, the fixing frame 202 and the extrusion spring 204 to limit the rotation of the rotating shaft 109 in one direction, so that after the user drives the rotating shaft 109 to continuously tighten the rubber binding rope 106 by twisting the cap 110, the rotating shaft 109 can ensure the stability of the binding of the entire wristband through the reverse limitation of the ratchet 201. When the user needs to loosen the entire strap, he only needs to move the locking boss 207 at the end of the matching frame 203 so that the matching boss 206 of the matching frame 203 cannot cooperate with the ratchet 201, thereby ensuring the normal free rotation of the rotating shaft 109, thereby completing the loosening of the entire wristband, greatly enhancing the practicality of the entire device.

[0032] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
