[0006] Furthermore, a groove is provided on the side of the socket, a plurality of ribs are fixed inside the groove, and a plurality of grooves are provided at equal angles along the circumference of the socket.

[0007] Furthermore, a T-shaped plate is fixed on the side of the adapter and is integrated with the adapter. A snap-in strip is fixed on the inner wall of the T-shaped plate. The snap-in strip is integrated with the T-shaped plate and is symmetrically arranged about the center line of the T-shaped plate. A number of snap-in strips are arranged on both sides of the T-shaped plate.

[0008] Furthermore, a first annular groove is provided inside the socket.

[0009] Furthermore, a second annular groove is provided inside the adapter, and a protrusion is integrally provided at the end of the adapter away from the second annular groove, and the third connector is plugged into the outside of the protrusion.

[0010] Furthermore, a first air hole is provided in the middle of the adapter.

[0011] Furthermore, a second air hole is provided in the middle of the third joint.

[0012] The beneficial effects of the utility model are:

[0013] A transfer port that can be installed forwards and backwards is provided, and both ends of the transfer port can be used to connect containers of different specifications. At the same time, the transfer port is snapped into the inside of the first joint, and then after the transfer port is removed, it can be directly connected with the first joint. Therefore, it can be used for vacuuming containers of different specifications, is not easy to lose, and reduces costs. 2. A first annular card groove is provided inside the socket, and a second annular card groove is provided inside the transfer port. When the first joint and the transfer port are installed, they are embedded and snapped together, which can increase the sealing when vacuuming and improve the vacuuming efficiency.

[0019] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] Please also refer to Figures 1 to 4 The vacuum pump connection sleeve of the embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1As shown, the vacuum machine connecting sleeve includes a socket 2 fixed inside the vacuum machine body 1, a first connector 3 is clamped inside the socket 2, an adapter 4 is clamped inside the first connector 3, the adapter 4 is rotatably clamped on the outside of the socket 2, one end of the adapter 4 is clamped with a second connector 5, and the other end is plugged with a third connector 13.

[0022] A groove 6 is provided on the side of the socket 2 , a plurality of ribs 7 are fixed inside the groove 6 , and a plurality of grooves 6 are provided at equal angles along the circumferential direction of the socket 2 .

[0023] At the same time, a T-shaped plate 8 is fixed on the side of the transfer port 4 and is integrated with the transfer port 4. A snap-in strip 9 is fixed on the inner wall of the T-shaped plate 8. The snap-in strip 9 is integrated with the T-shaped plate 8. The snap-in strip 9 is symmetrically arranged about the center line of the T-shaped plate 8. A number of snap-in strips 9 are arranged on both sides of the T-shaped plate 8. The snap-in strips 9 are also arranged in an interval manner on the inner wall of the T-shaped plate 8. A number of snap-in strips 9 form a group, and the number of all groups is consistent with the number of grooves 6.

[0024] After the adapter 4 is clamped in the first joint 3 , the adapter 4 can be rotated so that the clamping strip 9 inside the T-shaped plate 8 rotates and moves to the gap between the edges 7 inside the groove 6 , thereby stably installing the adapter 4 .

[0025] At the same time, a first annular groove 10 is provided inside the socket 2, and the first annular groove 10 is used to place the first connector 3; a second annular groove 11 is provided inside the adapter 4, and the second annular groove 11 is used to place the second connector 5; the adapter 4 is integrally provided with a protrusion 12 at the end away from the second annular groove 11, and the third connector 13 is plugged into the outside of the protrusion 12.
