Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and accompanying fig. 1-4, which are not intended to limit the present invention.

Example 1

The utility model provides a paper tube fastener, establishes bearing 2 on installation pole 1 including installation pole 1 and cover, the outside fixedly connected with ring base 3 of bearing 2, ring base 3 has a plurality of card foot 4 along the circumference equipartition, card foot 4 includes fixture block 41, the inboard of fixture block 41 and the outside fixed connection of ring base 3, the outside of fixture block 41 is the echelonment.

The utility model fixes the paper tube by inserting the fixture block 41 of the circular base 3 into the inner diameter of the paper tube, and the ladder-shaped design makes the paper tube adapt to a plurality of paper tubes with different inner diameters; because ring base 3 sets up on bearing 2, bearing 2 and installation pole 1 rotatable coupling, consequently when drawing the paper tube, ring base 3 can follow the paper tube and carry out synchronous rotation to reduce the friction, avoid the production of paper powder, be favorable to keeping the cleanness of product and equipment.

The mounting rod 1 is further fixedly sleeved with an upper limiting piece 5 and a lower limiting piece 6, the upper limiting piece 5 is attached to the upper end face of the bearing 2, and the lower limiting piece 6 is attached to the lower end face of the bearing 2. The fixing of the bearing 2 on the mounting rod 1 in the axial direction can be realized through the matching of the upper limiting piece 5 and the lower limiting piece 6, and the axial deviation of the bearing on the mounting rod 1 is avoided, so that the stabilizing effect on the paper tube is improved.
