In addition, the top of the lower case 20 further includes a latch assembly 21, and the latch assembly 21 includes a latch 211, and the latch 211 is used for connecting and locking with the upper case 40. Furthermore, the lower housing 20 further has a fifth boss 204 with an arc, and the fifth boss 204 is used for accommodating one end of the lower portion of the spring device 50.

FIG. 4 is a cross-sectional schematic view of outer sleeve 60 showing the inner surface of outer sleeve 60. The outer sleeve 60 has a cylindrical shape and is hollow inside. All of the lower and upper housings 20 and 40 and the portion to which the base 10 is applied are disposed within the outer sleeve 60. Referring to fig. 4, a first inner rim 601 is provided at a lower end of one-half of the inner wall of the outer sleeve 60, for example, the first inner rim 601 may be provided at one-third of the lower end of the outer sleeve 60. A second inner edge 603 is disposed above first inner edge 601, and first inner edge 601 and second inner edge 603 divide outer sleeve 60 into upper and lower portions, i.e., first portion 61 and second portion 62.

At least one first stopper rib 602 is vertically disposed below the first inner edge 601 of the outer sleeve 60, and for example, two first stopper ribs 602 may be disposed. When the lower casing 20 enters the outer sleeve 60 from the lower opening of the outer sleeve 60, the second boss 202 of the lower casing 20 is restrained at the first inner edge 601, preventing the lower casing 20 from moving axially upward inside the outer sleeve 60, and the notch band 203 of the lower casing 20 restrains the rotation angle of the first stopper rib 602 to a third angle, so that the lower casing 20 can rotate in the outer sleeve 60 by the third angle. In addition, one or more clamping ribs 605 are further arranged at the lower position of the first inner edge 601 of the outer sleeve 60, and the clamping ribs 605 are matched with the limiting convex ribs 121, so that the additional base 10 and the outer sleeve 60 can be relatively fixed.

In practical application, after the additional base 10 is fixed on the opening of the wine bottle, the lower casing 20 is first sleeved on the first boss 15 of the additional base 10, and then the additional base 10 and the lower casing 20 enter the outer sleeve 60 together from the lower opening of the outer sleeve 60. Assuming that the additional base 10 (and the bottle mouth) is fixed against rotation, the outer sleeve 60 is rotated. Because the rotation angle (the first angle) between the outer sleeve 60 and the adding base 10 is greater than the rotation angle (the third angle) between the outer sleeve 60 and the lower housing 20, and because the rotation angle (the third angle) between the outer sleeve 60 and the lower housing 20 is greater than the rotation angle (the second angle) between the adding base 10 and the lower housing 20, when the outer sleeve 60 is rotated, when the outer sleeve 60 and the adding base 10 are not rotated, the adding base 10 can drive the lower housing 20 to continue to rotate.

With continued reference to fig. 4, at least one second stop fin 604, for example, four second stop fins 604, is vertically disposed above the second inner edge 603 of the outer sleeve 60. The length of the second restraining ledge 604 is greater than the length of the first restraining ledge 602. The second stopper rib 604 serves to limit the rotation angle of the upper housing 40 within the outer sleeve 60.

With reference to fig. 5A and 5B, the upper housing 40 includes a pin slot 41, the pin slot 41 is integrally formed with the upper housing 40 and located inside the upper housing 40 to form an inner cavity 42 of the upper housing 40, and the inner cavity 42 is used for accommodating an upper end of the spring device 50. The lower end of the pin slot body 41 is provided with a notch 411 for accommodating the pin 211 of the lower case 20 and allowing the pin 212 to pass through the notch 411, and after the pin 212 is inserted into the notch 411 and rotated, the notch 411 locks the pin 212, so that the lower case 20 and the upper case 40 compress the spring. The upper shell 40 further includes a plurality of notches 43 disposed at the edge, and the notches 43 cooperate with the second limit protrusions 604 to limit the rotation angle of the upper shell 40 in the outer sleeve 60.

Referring collectively to fig. 6A and 6B, the components are mounted in connection in the manner of the present application. The adding base 10 is fixed on the opening of a wine bottle, then the lower shell 20 is sleeved at the first boss 15 of the adding base 10, then the adding base 10 and the lower shell 20 enter the outer sleeve 60 together from the lower opening of the outer sleeve 60, and the lower edge of the outer sleeve 60 is clamped at the third boss 13. The upper housing 40 is entered into the outer sleeve 60 from the upper opening of the outer sleeve 60 and the spring means 50 is arranged between the upper housing 40 and the lower housing 20. The notch 43 of the upper case 40 is aligned with the second stopper rib 604 and the upper case 40 is pressed downward.

Assuming that the additional base 10 (and the bottle mouth) is fixed against rotation, the outer sleeve 60 is rotated. Because the turned angle (first angle) between outer sleeve 60 and the additional base 10 is greater than the turned angle (third angle) between outer sleeve 60 and lower casing 20, and because the turned angle (third angle) between outer sleeve 60 and lower casing 20 is greater than the turned angle (second angle) between additional base 10 and lower casing 20, when rotating outer sleeve 60, when outer sleeve 60 and the additional base 10 do not rotate, the additional base 10 can drive down casing 20 and continue to rotate, make the latch 212 of lower casing 20 aim at and pass notch 411, latch 212 inserts in notch 411 and rotatory back, notch 411 locking latch 212, thereby make lower casing 20 with go up casing 40 compression spring. The additive sleeve according to the present application is assembled.

To release the device, the outer sleeve 60 is rotated in the opposite direction to disengage the catch 212 from the slot 411 whereupon the spring means 50 is released and the stored energy of compression of the spring means 50 causes the upper housing 40 to be ejected out of the outer sleeve 60.

The above description is only an example of the present application and is not intended to limit the present application, and various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement or the like made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
