[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] Please see Figure 1-13 This invention provides two technical solutions:

[0033] Example 1

[0034] A portable tape dispenser includes a transparent cover plate 1, a mounting base 2, and a storage tray 3. The storage tray 3 is rotatably mounted on one side of the mounting base 2, and the mounting base 2 is rotatably mounted on one side of the transparent cover plate 1. A first card plate 14 is fixedly connected to the front and rear sides of one side of the transparent cover plate 1. A first slot 15 adapted to the first card plate 14 is opened on one side of the mounting base 2. A second card plate 16 is fixedly connected to the front and rear sides of the other side of the mounting base 2. A second slot 17 adapted to the second card plate 16 is opened on one side of the storage tray 3. Several semi-circular fitting grooves 18 are opened on the top of both the mounting base 2 and the storage tray 3. Semi-circular fitting blocks 19 adapted to the semi-circular fitting grooves 18 are fixedly connected to the bottom of both the transparent cover plate 1 and the mounting base 2. For detailed explanation: This device is made of PP material, and the cutting end of the PP material blade 5 is set as a serrated edge.

[0035] Furthermore, to facilitate the indication of the extension and retraction stop of the blade 5, a telescopic component 41 is provided on the rear side of the inner cavity of the mounting base 2, and the blade 5 is provided on the front side of the telescopic component 41. Positioning convex sliders 6 are fixedly connected to both sides of the bottom of the blade 5. Positioning grooves 21 that slide and adapt to the positioning convex sliders 6 are provided on both sides of the top of the mounting base 2. The telescopic component 41 is a wave-shaped telescopic spring assembly 4, and the rear side of the wave-shaped telescopic spring assembly 4 is fixedly connected to the rear side of the inner cavity of the mounting base 2, while the front side of the wave-shaped telescopic spring assembly 4 is fixedly connected to the rear side of the blade 5. For detailed explanation: the blade 5 and the mounting base... The connection between the blade 5 and the mounting base 2 is not limited to injection molding. The elastic medium between the blade 5 and the mounting base 2 can be achieved by using a hanging spring or a hanging rubber band. When changing the elastic medium, it is only necessary to adapt the injection molding to the corresponding hanging injection groove. The blade 5 is fixedly provided with a limiting protrusion 9. The top of the blade 5 is fixedly connected with a push block 10. The front and rear sides of the top of the transparent cover plate 1 are respectively provided with limiting grooves 11 and push-pull grooves 12 that are adapted to the limiting protrusion 9 and the push block 10, respectively. As a detailed explanation, the bottom of the transparent cover plate 1 is provided with a placement groove that is adapted to the telescopic component 41.

[0036] In order to facilitate the temporary attachment and support of the cut tape ends and avoid the problem of the tape ends being difficult to find, tape guide and placement arms 13 are fixedly connected to both sides of the front side of the mounting base 2.

[0037] In order to facilitate wearing, a wearing ring 20 is fixedly connected to the back of the storage card holder 3.

[0038] To facilitate the support of tape rings of different thicknesses, an arc-shaped support block 7 is fixedly installed inside the storage card holder 3. The arc-shaped support block 7 and the storage card holder 3 are integrally injection molded, and the arc-shaped support block 7 can move up and down elastically. When the arc-shaped support block 7 and the storage card holder 3 are integrally injection molded, they are connected by a PP plastic strip, which can assist the arc-shaped support block 7 to move up and down elastically. Elastic side plates 8 are fixedly installed on both sides of the bottom of the inner cavity of the storage card holder 3. A displacement groove 22 matching the elastic side plates 8 is opened at the top of the inner cavity of the storage card holder 3. In detail, when the elastic side plates 8 are integrally injection molded, they will unfold on both sides of the storage card holder 3. The movable end of the side plate 8 is cylindrical, which can easily be elastically inserted into the displacement groove 22. The elastic side plate 8 can easily limit the placement position of tapes of different widths by elastically expanding and contracting. That is, the upper cylindrical part of the elastic side plate 8 is tensioned and limited at different inclinations of the displacement groove 22, so that the curved part in the middle of the elastic side plate 8 can continuously approach the tape loop. It should be noted that in the normal state, the elastic side plate 8 will clamp the tape inward due to the inclination of the displacement groove 22. When encountering a wide tape, the cylindrical part of the elastic side plate 8 will move outward from the displacement groove 22, and the curved part in the middle of the elastic side plate 8 will be compressed downward to form a rebound force. When the tape is removed, the above-mentioned rebound force will reset the cylinder from the outside of the displacement groove 22 to the inside.

[0039] Example 2

[0040] A portable tape dispenser includes a transparent cover plate 1, a mounting base 2, and a storage tray 3. The storage tray 3 is rotatably mounted on one side of the mounting base 2, and the mounting base 2 is rotatably mounted on one side of the transparent cover plate 1. A first card plate 14 is fixedly connected to the front and rear sides of one side of the transparent cover plate 1. A first slot 15 adapted to the first card plate 14 is opened on one side of the mounting base 2. A second card plate 16 is fixedly connected to the front and rear sides of the other side of the mounting base 2. A second slot 17 adapted to the second card plate 16 is opened on one side of the storage tray 3. Several semi-circular fitting grooves 18 are opened on the top of both the mounting base 2 and the storage tray 3. Semi-circular fitting blocks 19 adapted to the semi-circular fitting grooves 18 are fixedly connected to the bottom of both the transparent cover plate 1 and the mounting base 2. For detailed explanation: This device is made of PP material, and the cutting end of the PP material blade 5 is set as a serrated edge.

[0041] Furthermore, to facilitate the indication of the extension and retraction stop position of the blade 5, a telescopic assembly 41 is provided on the rear side of the inner cavity of the mounting base 2, and the blade 5 is provided on the front side of the telescopic assembly 41. Positioning convex sliders 6 are fixedly connected to both sides of the bottom of the blade 5. Positioning grooves 21 that slide and adapt to the positioning convex sliders 6 are provided on both sides of the top of the mounting base 2. The telescopic assembly 41 is a wave telescopic spring assembly 4, which consists of a wave telescopic spring 401 and an assembly block 402, and the assembly block 402 is fixedly set on the wave telescopic spring 401. The front side of the wave telescopic spring 401 is fixedly connected to the rear side of the blade 5. The top of the mounting base 2 is provided with an assembly groove 403 that matches the assembly block 402. The blade 5 is fixedly provided with a limiting protrusion 9. The top of the blade 5 is fixedly connected with a push block 10. The front and rear sides of the top of the transparent cover plate 1 are respectively provided with a limiting groove 11 and a push-pull groove 12 that match the limiting protrusion 9 and the push block 10. As a detailed explanation, the bottom of the transparent cover plate 1 is provided with a placement groove that matches the wave telescopic spring assembly 4.

[0042] In order to facilitate the temporary attachment and support of the cut tape ends and avoid the problem of the tape ends being difficult to find, tape guide and placement arms 13 are fixedly connected to both sides of the front side of the mounting base 2.

[0043] In order to facilitate wearing, a wearing ring 20 is fixedly connected to the back of the storage card holder 3.

[0044] To facilitate the support of tape rings of different thicknesses, an arc-shaped support block 7 is fixedly installed inside the storage card holder 3. The arc-shaped support block 7 and the storage card holder 3 are integrally injection molded, and the arc-shaped support block 7 can elastically move up and down. Elastic side plates 8 are fixedly installed on both sides of the bottom of the inner cavity of the storage card holder 3. A displacement groove 22, matching the elastic side plates 8, is opened at the top of the inner cavity of the storage card holder 3. In detail: when the elastic side plates 8 are integrally injection molded, they unfold to the sides of the storage card holder 3. Furthermore, the movable end of the elastic side plate 8 is cylindrical, making it easy to elastically engage with the displacement groove 22. The elastic extension of the side plate 8 facilitates the placement of tapes of different widths. Specifically, the upper cylindrical part of the elastic side plate 8 is tensioned and limited at different inclinations of the displacement groove 22, which allows the curved part in the middle of the elastic side plate 8 to continuously approach the tape loop. It should be noted that in the normal state, the elastic side plate 8 will clamp the tape inward due to the inclination of the displacement groove 22. When encountering a wide tape, the cylindrical part of the elastic side plate 8 will move outward from the displacement groove 22, and the curved part in the middle of the elastic side plate 8 will compress downward to form a rebound force. When the tape is removed, the rebound force will reset the cylinder from the outside of the displacement groove 22 to the inside.

[0045] The advantages of Example 2 compared to Example 1 are: it increases the installation method of the telescopic component 41, optimizes the injection molding conditions, and facilitates the disassembly and replacement of the entire telescopic component 41.

[0046] When in use, open the mounting base 2 on the top of the storage card holder 3, then put the tape inside the storage card holder 3, then reset the mounting base 2 to the top of the storage card holder 3, and during the reset, it is locked by the second card plate 16 and the second card slot 17. Then pull open one end of the tape, so that the pulled tape passes through the gap between the two tape guide placement arms 13.

[0047] When the tape needs to be cut, push the push block 10. The push block 10 drives the blade 5 and the limiting protrusion 9 to move. During the movement, the limiting protrusion 9 will cooperate with the limiting groove 11. At this time, the blade 5 extends from the front of the mounting base 2 and pierces and cuts the smooth back of the tape. It should be noted that when cutting the tape, the device should be held firmly with the palm of the hand. During the grip, the arc-shaped support block 7 should be lifted from the bottom center of the storage card 3 to temporarily stop the tape during cutting and prevent it from rotating randomly, which would affect the cutting.

[0048] When the blade 5 retracts, press the limiting protrusion 9 first, causing the limiting protrusion 9 to elastically move downward and disengage from the limiting groove 11. After the limiting protrusion 9 loses its limiting position, the wave telescopic spring 401 will reset and pull the blade 5 back, causing the limiting protrusion 9 to move to the bottom of the transparent cover plate 1 along with the retraction of the blade 5.
