In the present embodiment, the extension 344 includes a plurality of tab structures 3441, and the plurality of tab structures 3441 are disposed on the outer surface of the sleeve main body 342 in a vaulted shape. For example, the tab structures 3441 are four in number, and four tab structures 3441 are uniformly disposed on the outer surface of the sleeve main body portion 342, i.e. the included angle between the planes of two adjacent tab structures 3441 is 90 degrees. In other embodiments, the number of the flap structures 3441 can be two, three, five or more, which is sufficient for fixing the rolled tissue. The extension 344 may be a protrusion disposed on the outer surface of the sleeve main body 342, so as to fix the rolled tissue.

Referring to fig. 5 and 6, the sealing element 40 is disposed at one end of the lifting rod assembly 30 and located in the bracket base 10, so as to abut against the suction cup 20 and seal the communication hole 22 under the driving of the lifting rod assembly 30, or separate from the suction cup 20 and connect the communication hole 22. A seal 40 is movably disposed between the outer housing 11 and the suction cup mounting shell 13. For example, the sealing member 40 is selectively urged against the top wall 111 of the housing 11 or the suction cup 20 by the lifting rod 32.

The sealing member 40 is disposed at one end of the pull rod 32, i.e., the sealing member 40 is disposed at a side of the pull rod body 321 away from the pull end 323. In this embodiment, the sealing member 40 can be fixed to the lifting rod 32 by a screw, for example, one end of the lifting rod 32 is provided with an internal thread, the sealing member 40 is provided with a screw through hole 42 (fig. 2), and the screw can pass through the screw through hole 42 to match with the internal thread of the lifting rod 32, so as to fix the sealing member 40 to one end of the lifting rod 32. In other embodiments, the seal 40 may be secured to the lift rod 32 by adhesive or the like.

Referring to fig. 7 and 8, in one embodiment, the roll paper holder 1 further includes an elastic member 50, and the elastic member 50 is disposed between the holder base 10 and the sealing member 40 and used for providing an acting force for the sealing member 40 to close the communicating hole 22, improving the sealing performance of the sealing member 40, preventing the sealing member 40 from leaking air, and enabling the roll paper holder 1 to be fixed on a surface to be adsorbed. For example, the elastic member 50 is located between the top wall 111 and the sealing member 40, and the elastic member 50 is further disposed around the lifting bar assembly 30 and received in the receiving groove 117, so as to prevent the elastic member 50 from separating from the lifting bar assembly 30 during the expansion and contraction process.

When the sealing member 40 blocks the communication hole 22, the elastic member 50 abuts between the top wall 111 and the sealing member 40 to press the sealing member 40 against the connection boss 26 and block the communication hole 22, thereby improving the sealing performance of the sealing member 40. When the user lifts the lifting rod assembly 30, the sealing member 40 is also moved upward, and the elastic member 50 is compressed. When the user releases the lifting rod assembly 30, the elastic member 50 is restored and generates an elastic force, which drives the sealing member 40 and the lifting rod assembly 30 to move downward, so that the sealing member 40 closes the communication hole 22. In the present embodiment, the elastic member 50 is a compression spring.

With continued reference to fig. 5 and 6, the operation of the roll paper holder 1 according to the present invention will be described with a specific embodiment.

As shown in fig. 5, when the roll paper support 1 is placed on a table, air between the suction cup 20 and the table is squeezed out, the sealing member 40 at the bottom of the lifting rod 32 seals the communication hole 22 of the suction cup 20 under the action of gravity of the lifting rod assembly 30, so that the suction cup 20 is in a vacuum adsorption state, and the roll paper support 1 is firmly fixed on the table.

As shown in fig. 6, when the lifting rod 32 is lifted, the sealing member 40 at the bottom of the lifting rod 32 is moved upward, the communication hole 22 is opened, the suction cup 20 communicates with the outside through the communication hole 22 to release the vacuum suction state, and the user can move the roll paper holder 1 freely.

To sum up, the utility model provides a stock form support 1, can drive sealing member 40 to seal the intercommunicating pore 22 of sucking disc 20 or make the intercommunicating pore 22 of sucking disc 20 switch on through operating the lifting rod assembly 30, when the air in sucking disc 20 is extruded and intercommunicating pore 22 is sealed, the inside vacuum that forms of sucking disc 20, stock form support 1 can be firmly in waiting to adsorb the surface; when the communication hole 22 is communicated, the suction cup 20 is communicated with the outside through the communication hole 22 to release the vacuum adsorption state, so that the roll paper support 1 is separated from the surface to be adsorbed; the roll paper support 1 is good in stability, simple to operate and convenient to move.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the scope of the present invention.
