[0048] The second through hole 305d and the vent 305e communicate with the first threaded groove 305c. Multiple vents 305e are provided around the second through hole 305d. In this embodiment, three vents 305e are provided.

[0049] The other end of the tube 302 is connected to a nut 302a, and a sealing gasket 302b is provided on one side of the nut 302a;

[0050] A support tube 306 is provided in the constraint tube 304. The support tube 306 passes through the nut 302a. An air inlet 306a is provided on the side wall of the support tube 306. An annular plate 306b is provided on the outside of the support tube 306. The annular plate 306b is connected to the first vent plug 305 through the second spring 306c.

[0051] Nut 302a is threaded to the other end of tube 302, and support tube 306 passes through both nut 302a and sealing gasket 302b, which is sealed by sealing gasket 302b.

[0052] The spring constant of the first spring 305b is less than that of the second spring 306c.

[0053] A support nut 307 is provided in the support tube 306. One end of the support nut 307 is provided with a second threaded groove 307a. One end of the support tube 306 is provided with an inner ring 306d. The other end of the support tube 306 is provided with a second vent plug 310. One end of the second vent plug 310 is provided with an embedded tube 310a, which is embedded in the support tube 306.

[0054] The inner ring 306d limits the support nut 307, confining the support nut 307 inside the support tube 306.

[0055] A support valve tube 308 is provided in the inner ring 306d. A shoulder 308a is provided on the outer side of the middle of the support valve tube 308. One end of the support valve tube 308 is provided with a first external thread 308b and connected to a first thread groove 305c. The other end of the support valve tube 308 is provided with a second external thread 308c and connected to a second thread groove 307a.

[0056] The shoulder 308a is connected and sealed to the inner ring 306d.

[0057] A diaphragm 309 is provided on one side of the first vent plug 305. A shaft 309a is provided at one end of the diaphragm 309. A cone plug 309b is provided at the end of the shaft 309a. The shaft 309a is located in the second through hole 305d. The cone plug 309b is embedded in the support valve tube 308.

[0058] It also includes an adjusting component 500, which includes a handle 501. The handle 501 is connected to the shaft of the quick connector 300. One end of the handle 501 is provided with a retaining ring 501a. An eccentric shaft 501b is eccentrically provided on the retaining ring 501a. A cylinder 502 is sleeved on the eccentric shaft 501b. A side groove 502a is provided on the side of the cylinder 502. The end of the second vent plug 310 is embedded in the side groove 502a.

[0059] It should be noted that there are two retaining rings 501a, with a gap between them to accommodate the cylinder 502. The outer side of the retaining ring 501a has a circular groove structure for accommodating the rotating pin and quick connector 300 to achieve shaft connection, allowing the handle to rotate. An eccentric shaft 501b is connected to the two retaining rings 501a. The axis of the eccentric shaft 501b does not coincide with the axis of the retaining ring 501a. A central hole is provided at the axis of the cylinder 502, and the eccentric shaft passes through the central hole.

[0060] Therefore, when the handle 501 is turned 180°, the eccentric shaft 501b drives the cylinder 502 to rotate around the axis of the retaining ring 501a. Since the end of the second vent plug 310 is embedded in the side groove 502a, it limits the rotation of the cylinder 502. Therefore, after slight compression deformation between the cylinder 502 and the second vent plug 310, the eccentric shaft 501b rotates 180° relative to the axis of the retaining ring 501a, and the cylinder 502 moves laterally a certain distance relative to the axis of the retaining ring 501a. (Refer to...) Figure 6 The eccentric shaft 501b is located to the right of the axis of the retaining ring 501a. When the handle 501 is turned downwards, the eccentric shaft 501b is located to the left of the axis of the retaining ring 501a, and at the same time, the cylinder 502 moves laterally to the left by a certain distance.

[0061] Specifically, refer to Figure 8 The diagram shows the air circuit structure for slow charging. Specifically, in the diagram, the eccentric shaft 501b is located to the left of the axis of the retaining ring 501a. Therefore, the second vent plug 310 and the support tube 306 are both subjected to leftward compressive force. The first vent plug 305 is also compressed to the left by the second spring 306c. The second sealing ring 305a seals the connection between the first vent plug 305 and the through hole 304b. Gas enters the constraint tube 304 from the air inlet pipe 400, passes through the gap between the support nut 307 and the support tube 306, the gap between the support nut 307 and the shoulder 308a, and the gap between the second external thread 308c and the second thread groove 307a, and enters the support valve tube 308. Then, through the air hole 305e, the diaphragm 309 is pushed open and enters the tube 302, slowly supplying gas to the plug 301.

[0062] By slowly supplying air, the first tubing 101 and the second tubing 102 are gradually opened, allowing time for the head to adjust.

[0063] Reference Figure 7 This is a schematic diagram of the air circuit structure for fast charging. When the handle 501 is turned downwards, the eccentric shaft 501b moves to the right of the axis of the retaining ring 501a, and the cylinder 502 moves to the right a certain distance. The second vent plug 310 and the support tube 306 both move to the right under the action of the spring. The first spring 305b also pushes the first vent plug 305 to the right. The second sealing ring 305a no longer seals the connection between the first vent plug 305 and the through hole 304b. Gas enters the constraint tube 304 from the air inlet pipe 400 and directly enters the cavity 302 from the gap between the first vent plug 305 and the first through hole 304b, quickly supplying air to the plug 301, so that the first rubber tube 101 and the second rubber tube 102 are quickly inflated.

[0064] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
