[0017] The following further describes the present utility model in conjunction with the drawings and specific embodiments.

[0018] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown in the figure, a tape dispenser includes a base 1 and a tape fixing wheel assembly. The tape fixing wheel assembly includes a pin shaft 2, a small fixing wheel 3, and a large fixing wheel 4 that are coaxially arranged. The center of the large fixing wheel 4 is provided with an accommodation hole 41 arranged axially. The small fixing wheel 3 is inserted into the accommodation hole 41. The center of the small fixing wheel 3 is provided with an axially penetrating shaft hole 31. The pin shaft 2 is inserted into the shaft hole 31, and both ends of the pin shaft 2 are rotatably connected to the base 1.

[0019] The number of small fixing wheels 3 and the number of large fixing wheels 4 are both two. The two large fixing wheels 4 are arranged coaxially and side by side, and the two small fixing wheels are arranged coaxially and side by side.

[0020] At least two convex ribs 32 are evenly distributed along the circumferential direction on the outer wall of the small fixing wheel 3. In this example, there are four groups of convex ribs 32 evenly distributed along the circumferential direction of the small fixing wheel 3, and the convex ribs 32 extend axially along the small fixing wheel 3. The convex ribs 32 play a role in tightening and strengthen the insertion stability between the small fixing wheel 3 and the large fixing wheel 4.

[0021] The protruding height of one end of the convex rib 32 is greater than that of the other end, the width of one end of the convex rib 32 is greater than that of the other end, and the inner diameter of one end of the accommodation hole 41 is greater than that of the other end.

[0022] A limiting protrusion 411 is provided on the inner wall of the other end of the accommodation hole 41. In this way, the small fixing wheel 3 is inserted into the accommodation hole 41 from one end, and the other end of the accommodation hole 41 forms a limit. The ends of the two large fixing wheels 4 with the limiting protrusions 411 face each other, and the other ends are close to each other to prevent the small fixing wheel 3 from disengaging outward during rotation.

[0023] The base 1 is provided with an installation groove 10. The two side walls of the installation groove 10 are provided with fitting grooves 101 that are connected and matched with both ends of the pin shaft 2. The fitting groove 101 includes two connected card slots 1011. The horizontal heights of the lower slot walls of the two card slots 1011 are different, and an opening 1012 is provided at the upper end of the fitting groove 101. The two card slots 1011 form two gears. The pin shaft 2 can be at two non-horizontal heights. When using a large tape, the pin shaft 2 is on the card slot with a higher horizontal height, and when using a small tape, the pin shaft 2 is on the card slot with a lower horizontal height.

[0024] A blade 5 is provided at the front end of the base 1. The blade 5 is parallel to the horizontal plane, and the length direction of the blade 5 forms an acute angle with the pin shaft 2. The blade 5 is slightly inclined to facilitate piercing the tape.

[0025] The tape fixing wheel assembly of the present utility model includes two small fixing wheels 3 and two large fixing wheels 4, and the two large fixing wheels 4 are respectively sleeved outside the two small fixing wheels 3. The tape fixing wheel assembly can be adjusted for use according to tapes of different sizes. Commonly used tapes are roughly of three types: one is the size of a commonly used small office tape, with a small core size and a narrow tape; the second is the size of a commonly used double-sided tape in the office, with a large core size but a narrow tape; the third is the size of a commonly used sealing tape, with a large core size and a wide tape. When it is necessary to use the third type of large-sized tape, the two large fixing wheels 4 are respectively sleeved outside the two small fixing wheels 3, and the tape is installed on the two large fixing wheels 4. When it is necessary to use the second type of tape, the large fixing wheel 4 is sleeved outside the small fixing wheel 3. At this time, one set of small fixing wheels 3 and large fixing wheels 4 can be selected, or two sets of small fixing wheels 3 and large fixing wheels 4 can be selected. One tape can be used and installed on one large fixing wheel 4, or two tapes can be used simultaneously and installed on the two large fixing wheels 4 respectively. The tape seat can use two tapes simultaneously. When it is necessary to use the first type of tape, the large fixing wheel 4 is removed, and the tape is installed on the small fixing wheel 3 for use. One tape or two tapes can also be selected for use. The tape seat of the present utility model can adjust the tape fixing wheels according to requirements to adapt to tapes of different sizes, enabling the product to meet more usage requirements.
