[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1-7 , which is the first embodiment of the utility model, and this embodiment provides a binding mechanism, including a binding component 100, which includes a strap 103, a plurality of connecting plates 101 arranged on the strap 103, and a fixing member 102 arranged at one end of the connecting plate 101; and also includes a docking component 300, which includes a winding component 301 arranged on one side of the strap 103, and a stepping component 302 arranged at one end of the winding component 301.

[0034] Specifically, the winding component 301 includes a fixed block 301a arranged on one side of the strap 103, a rotating shaft 301b arranged inside the fixed block 301a, and a knob 301c arranged at one end of the rotating shaft 301b; wherein, one end of the strap 103 is fixedly connected to the rotating shaft 301b, the fixed block 301a is fixedly connected to one end of the strap 103, the rotating shaft 301b is rotatably connected to the fixed block 301a, and the knob 301c is fixedly connected to the rotating shaft 301b. Rotating the knob 301c drives the rotation, so that the strap 103 will gradually be wound around the rotating shaft 301b, thereby realizing the winding function.

[0035] Further, the stepping assembly 302 includes a ratchet 302a disposed at one end of the rotating shaft 301b, a limit block 302b disposed on the fixed block 301a near the ratchet 302a, a pawl 302c disposed inside the limit block 302b, and a screw 302d disposed on the pawl 302c. The ratchet 302a is fixedly connected to the rotating shaft 301b, the ratchet 302a is slidably disposed in the limit block 302b, the pawl 302c cooperates with the ratchet 302a, the screw 302d is threadedly connected to the limit block 302b, the pawl 302c is rotatably connected to one end of the screw 302d, and the rotating screw 302d drives the pawl 302c to slide in the limit block 302b. Due to the restrictions of the ratchet 302a and the pawl 302c, the strap 103 will not be loose during use. .

[0036] Operation process: When winding, firstly, the screw rod 302d is reversed and rotated so that the pawl 302c is separated from the ratchet wheel 302a, thereby removing the restriction of the ratchet wheel 302a;

[0037] When tied around the waist, first rotate the shaft 301b through the knob 301c so that the strap 103 can fit the waist, and then rotate the screw 302d forward to make the pawl 302c engage with the ratchet 302a, so that the reverse rotation will not be locked, and the stepping of the ratchet 302a and the pawl 302c can achieve a fine-tuning effect.

[0038] Example 2

[0039] Reference Figure 1-7, which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a binding mechanism; it also includes an application component 200, which includes a pneumatic component 201 disposed at one end of the connecting plate 101, a transmission component 202 disposed at one side of the pneumatic component 201, a control component 203 disposed below the transmission component 202, and a power supply component 204 disposed at the other side of the pneumatic component 201, wherein the transmission component 202 and the control component 203 are both disposed inside the fixing member 102;

[0040] Three connecting plates 101 are provided, all of which are fixed on the surface of the strap 103. One end of each connecting plate 101 is fixedly connected to the pneumatic component 201, the fixing part 102 and the power supply component 204 respectively. The pneumatic component 201, the transmission component 202, the control component 203 and the power supply component 204 can be carried through the strap 103. The pneumatic component 201 and the transmission component 202 are designed to generate high-pressure gas. The design of the control component 203 can monitor and control the change of air pressure. The design of the power supply component 204 facilitates the disassembly and replacement of batteries, thereby providing sufficient power for the cooperation of the above components.

[0041] Specifically, the pneumatic component 201 includes an air pump 201a arranged in a fixed frame 102c, and a compressor 201b arranged on one side of the air pump 201a. The air pump 201a is arranged inside the fixed frame 102c. Through the cooperation between the air pump 201a and the compressor 201b, high-pressure gas can be generated. The high-pressure pneumatic will be transported to the control component 203 through the transmission component 202. The air pump 201a adopts the SFKY series brushless micro air pump, which has the advantage of a long-life brushless micro air pump, a gas circulation pump, a pressure of 80-90kPa, a flow rate of 6-9 liters / minute, and the volume of the air pressure bottle on one side of the air pump 201a is 0.1L.

[0042] Furthermore, the transmission component 202 includes an air inlet 202b arranged at one end of the rear shell body 102b, an air outlet 202c arranged at the other end of the rear shell body 102b, and a pressure bottle 202a arranged between the front shell body 102a and the rear shell body 102b; wherein, the air inlet 202b and the air outlet 202c are both fixedly connected to the pressure bottle 202a, and the generated high-pressure gas enters the pressure bottle 202a through the air inlet 202b, and then is monitored and controlled by the control component 203, so that the high-pressure gas flows out from the air outlet 202c.

[0043] Furthermore, the control component 203 includes a connecting block arranged below the air pressure bottle 202a, a pressure valve 203a arranged at one end of the connecting block, and a controller 203b arranged on one side of the pressure valve 203a. The pressure valve 203a can monitor the air pressure value of the air pressure bottle 202a, and the controller 203b is centrally installed in the shell for easy carrying. The pressure valve 203a and the controller 203b can adjust the air pressure to meet different injection requirements. The pressure valve 203a adopts an electronic single-seat electric regulating valve and is electrically connected to the controller 203b. The external controller transmits the threshold value to the controller 203b through the signal interface.

[0044] Furthermore, the power component includes a battery box 204a arranged at one end of the connecting plate 101, and a battery body 204b arranged inside the battery box 204a. The battery body 204b is slidably connected to the battery box 204a. By inserting the battery body 204b into the battery box 204a, the function of providing power can be realized, and the side of the battery body 204b and the side of the battery box 204a are self-locked by friction. The battery body 204b can be a disposable battery or a rechargeable battery, which can achieve ultra-long standby time. The battery body 204b can use a universal battery pack and be matched according to requirements.

[0045] The rest of the structure is the same as that of Example 1.

[0046] Operation process: When using the binding mechanism, the strap 103 is used to fix the waist, and the battery body 204b is inserted into the battery box 204a. At this time, the pressure valve 203a can monitor the air pressure value of the air pressure bottle 202a and send the air pressure value to the controller 203b. When the air pressure value is lower than the preset threshold, the controller 203b generates a first instruction and sends the first instruction to the air pump 201a. The air pump 201a starts to generate high-pressure gas according to the first instruction, and sends the generated high-pressure gas to the air pressure bottle 202a to increase the air pressure value in the air pressure bottle 202a. When the air pressure value is equal to or greater than the preset threshold, the controller 203b generates a second instruction and sends the second instruction to the air pump 201a, and the air pump 201a no longer generates high-pressure gas.

[0047] Example 3

[0048] Reference Figure 8 , which is the third embodiment of the utility model. It is different from the previous embodiment in that it also includes a locking assembly 400, which includes a clamping plate 401 arranged at one end of the strap 103, an inclined plate 402 arranged on one side of the clamping plate 401, and a slot plate 403 arranged at the other end of the strap 103. The material of the inclined plate 402 is elastic. When the clamping plate 401 is engaged with the slot plate 403, the inclined plate 402 is flush with the slot plate 403. After that, the inclined plate 402 loses its constraint and rebounds to enter the empty slot on the slot plate 403, thereby completing the locking.

[0049] The remaining structures are the same as those in Example 1 or 2.
