[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0023] like Figure 1-5 As shown, a tape cutting table includes a shell 1, on which a rotating column 2 is rotatably arranged on a support plate portion 11, a locking ring 3 is coaxially rotatably arranged in the rotating column 2, a receiving cavity 21 is opened in the rotating column 2, and arc-shaped protruding portions 31 are arranged in a circular array on the locking ring 3. The locking ring 3 is driven to rotate so that the protruding portion 31 moves synchronously from the receiving cavity 21 to the outside of the rotating column 2 to be expanded and tightened in the hole in the tape roll, and the tape roll is coaxial with the rotating column 2.

[0024] Specifically, Figure 1 As shown, a rotating column 2 is rotatably provided on the support plate portion 11 of the housing 1, and a cutting blade 12 is also provided on the end of the housing 1. The locking ring 3 is rotatably provided on the rotating column 2, and the root end of the extension portion 31 of the locking ring 3 is located in the accommodating cavity 21, as shown in FIG. Figure 5As shown, when it is necessary to first rotate the locking ring 3 counterclockwise so that the protruding portion 31 follows the locking ring 3 and retracts into the accommodating chamber 21, then the hollow sleeve of the tape roll is set on the rotating ring 2, and then the locking ring 3 is rotated clockwise. At this time, the protruding portion 31 follows the locking ring 3 to rotate and move and protrude to the outside of the rotating column 2, so that the protruding portion 31 after extending is abutted and expanded in the middle hole of the tape roll, so that the locking ring 3 is used to fix the tape roll and the rotating column 2 coaxially. When the tape roll is used, the tape roll and the rotating column 2 rotate coaxially to release the tape, and then the cutting blade 12 can be used to cut the tape. Since the tape roll and the rotating column 2 rotate coaxially to release the tape, the radial random jitter of the tape roll during rotation can be avoided, and the tape roll can be prevented from accidentally falling off. At the same time, it is also convenient for manual gripping of the shell to use the tape roll. Secondly, the locking ring 3 and the extension portion 31 are used to expand and fix tape rolls of different specifications, thereby improving the applicability of the cutting table.

[0025] Furthermore, a locking bolt 5 is threadedly mounted on the locking ring 3 , and the locking bolt 5 can be rotated to make it contact with the rotating column 2 , thereby keeping the locking ring 3 and the rotating column 2 relatively locked.

[0026] In the above technical solution, the locking ring 3 is used to fix the tape roll coaxially with the rotating column 2. When the tape roll is used, the tape roll and the rotating column 2 rotate coaxially to release the tape, and then the tape can be cut by the cutting blade 12. Since the tape roll and the rotating column 2 rotate coaxially to release the tape, the tape roll can be prevented from generating random radial vibration during the rotation process, and the tape roll can be prevented from accidentally falling off, and it is also convenient to manually hold the shell to use the tape roll. Secondly, the locking ring 3 and the extension 31 are used to make it possible to expand and fix tape rolls of different specifications, thereby improving the applicability of the cutting table.

[0027] As a further embodiment of the present invention, a cylindrical flexible abutment 4 is provided at the end of the extension portion 31, and the extension portion 31 synchronously moves out of the accommodating cavity 21 and extends out of the rotating column 2 so that the flexible abutment 4 synchronously abuts against the hole in the tape roll.

[0028] Specifically, a cylindrical flexible resistance member 4 is provided on the end of the extension portion 31. When the locking ring 3 is rotated clockwise, the extension portion 31 rotates with the locking ring 3 and extends to the outside of the rotating column 2, so that after the extension portion 31 is extended, the flexible resistance member 4 contacts and expands in the middle hole of the tape roll, so that the locking ring 3 is used to fix the tape roll and the rotating column 2 coaxially, and the flexible resistance member 4 is used to contact and expand in the middle hole of the tape roll, thereby improving the fixing stability between the rotating column 2 and the tape roll and improving the stability in use.

[0029] As an embodiment further provided by the present invention, inner grooves 41 are symmetrically provided on the flexible resisting member 4 .

[0030] Specifically, the flexible resistance member 4 is symmetrically provided with inner grooves 41. When the flexible resistance member 4 is in contact with and expanded in the middle hole of the tape roll, the flexible resistance member 4 is in contact with the hollow inner deformation of the tape roll to deform the inner groove 41, and then the air in the inner groove 41 is squeezed out, and the inner wall of the inner groove 41 is in contact with the inner wall of the middle hole of the tape roll, so that the inner groove 41 has a negative pressure to adsorb and fix it on the tape roll, further improving the fixing stability of the flexible resistance member 4 to the tape roll, and avoiding the radial random jitter caused by the loosening of the tape roll.

[0031] As an embodiment further provided by the present invention, a through hole 111 coaxial with the rotating column 2 is formed on the housing 1 , and an adjusting portion 32 extending to a first end of the through hole 111 is provided on the locking ring 3 .

[0032] Specifically, a through hole 111 coaxial with the rotating column 2 is formed on the shell 1. The through hole 111 is used to manually take the shell 1, and the adjustment portion 32 extends to the first end of the through hole 111 facing away from the rotating column 2. The locking sleeve 3 can be rotated relative to the rotating column 2 by rotating the adjustment portion 32, which is convenient for actual operation.

[0033] As an embodiment further provided by the present invention, a reset gear 6 and an elastic member for driving the reset gear 6 to rotate are provided on the rotating column 2, the reset gear 6 is meshed with the locking ring 3, and the reset gear 6 is driven by the elastic member to rotate so that the locking ring 3 rotates and the extension portion 31 extends to the outside of the rotating column 2.

[0034] Specifically, the reset gear 6 is meshed with the locking ring 3, and the elastic member always drives the reset gear 6 to rotate so that the locking ring 3 rotates and the extending portion 31 extends to the outside of the rotating column 2, that is, first the locking ring 3 is rotated counterclockwise through the adjustment portion 32 to retract the extending portion 31 into the accommodating cavity 21, and then the tape roll is put on the rotating column 2, and then the adjustment portion 32 is loosened, and the elastic member drives the reset gear 6 to rotate so that the locking ring 3 rotates and the extending portion 31 extends to the outside of the rotating column 2, thereby making the tape roll coaxially fixed with the rotating column 2, and the elastic member and the reset gear 6 are used to make the extending portion 31 automatically extend and expand in the hollow of the tape roll, which is convenient for the quick installation of the tape roll and improves the fixing stability of the tape roll.

[0035] The elastic member may be replaced by a spiral spring, an elastic plate, a spring or other elastic objects known to those skilled in the art.

[0036] As an embodiment further provided by the present invention, a flexible extrusion member 7 is provided in a circumferential array on the locking ring 3 , the flexible extrusion member 7 is located in the accommodating cavity 21 , and the flexible extrusion member 7 is located at the angle between the protruding portion 31 and the locking ring 3 .

[0037] Specifically, Figure 5 As shown, the flexible extrusion member 7 is located at the angle between the protruding portion 31 and the locking ring 3. When the locking ring 3 is rotated counterclockwise to allow the protruding portion 31 to enter the accommodating cavity 21, the flexible extrusion member 7 squeezes the protruding portion 31 inside the accommodating cavity 21 to prevent the protruding portion 31 from shrinking too quickly and causing damage to the flexible resistance member 4, thereby increasing the service life and stability of the locking ring 3.

[0038] As an embodiment further provided by the present invention, the flexible resisting member 4 is a rubber member.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
