Detailed Embodiments
[0029] The following further elaborates on the present utility model through specific embodiments and accompanying drawings. It should be understood that the described embodiments are only used to explain the present utility model and do not limit the present utility model. Embodiment
[0030] This embodiment is a simple tape cutting tool. As Figures 1 to 5 shown, this embodiment includes a base 1. There are holes 2 on the base 1. At both ends of the base 1, there are a first support plate 3 and a second support plate 4 respectively. The holes 2 can fix the base 1 to the workbench. The first support plate 3 and the second support plate 4 are perpendicular. A fixed shaft 7 is fixedly arranged on the first support plate 4, and a tape fixing device is arranged on the fixed shaft 7.
[0031] The tape fixing device includes a first fixing plate 8 and a second fixing plate 9. There is 1 central hole 10 and 3 strip-shaped grooves 11 on the first fixing plate 8. The strip-shaped grooves 11 are on the circular radius with the central hole 10 as the center on the first fixing plate 8. The length of the strip-shaped grooves 11 is less than the radius of the largest circle with the central hole 10 as the center on the first fixing plate 8. The angles between adjacent strip-shaped grooves 11 are the same, all being 120°. The second fixing plate 9 is provided with 1 central hole 10 and 3 arc-shaped grooves 12. The first fixing plate 8 is located on the side adjacent to the first support plate 3. The first fixing plate 8 and the second fixing plate 9 are strung on the fixed shaft 7 through the central hole 10 and can rotate around the fixed shaft 7.
[0032] It should be noted that in this embodiment, there are 3 strip-shaped grooves on the first fixing plate and 3 arc-shaped grooves on the second fixing plate. When the number of strip-shaped grooves on the first fixing plate and the number of arc-shaped grooves on the second fixing plate change, as long as the number of both is more than 2 and can fix the tape with the set fixing rods, it is within the scope of this embodiment.
[0033] The tape fixing device further includes fixing rods 13. Each strip-shaped groove 11 and arc-shaped groove 12 corresponds to a fixing rod 13. The fixing rods 13 pass through the strip-shaped grooves 11 on the first fixing plate 8 and the arc-shaped grooves 12 on the second fixing plate 9 and extend out of the second fixing plate 9, being perpendicular to the first fixing plate 8 and the second fixing plate 9. The part of the fixing rod 13 extending out of the second fixing plate 9 is a telescopic structure and can be telescopically extended to make the wide tape more stable.
[0034] It should be noted that in this embodiment, the parts of the 3 fixing rods extending out of the second fixing plate are telescopic structures and can fix the tape. When other structures that can extend the fixing rods are provided on the parts of the fixing rods extending out of the second fixing plate and can meet the use of wide tapes, or when arc-shaped pieces, rubber pieces, etc. are provided on the parts of the fixing rods extending out of the second fixing plate and can fit the circular inner diameter of the tape and make the tape fixing better, it is within the scope of this embodiment.
[0035] A connecting block 14 is fixedly arranged at one end of the fixed rod 13 on the first fixing plate 8. The connecting block 14 is clamped in the strip-shaped groove 11 and can slide in the strip-shaped groove 11. During the sliding process of any one of the connecting blocks 14 in the strip-shaped groove 11, the first fixing plate 8 remains stationary. The connecting block 14 drives the fixed rod 13 to slide, and the fixed rod 13 slides in the arc-shaped groove 12, driving the second fixing plate 9 to rotate around the central hole 10. The second fixing plate 9 drives the remaining fixed rods 13 to slide in the arc-shaped groove 12, and the remaining fixed rods 13 drive the respective connected connecting blocks 14 to slide in the strip-shaped groove 11, and all the connecting blocks 14 are always located on the same circle centered on the central hole 10, that is, the triangle formed by the 3 fixed rods 13 is always an equilateral triangle.
[0036] A tooth groove 16 is provided on the strip-shaped groove 11. As Figure 2 and Figure 5 shown, the strip-shaped groove 11 is a convex groove. The narrow side of the convex groove 11 faces the second fixing plate 9. An installation plate 15 clamped in the convex groove 11 is provided on the wide side of the convex groove 11. A tooth groove 16 along the length direction of the strip-shaped groove 11 is opened on the installation plate 15. The connecting block 14 is a square block. One end of the connecting block 14 is fixedly connected to the fixed rod 13. A push button is provided at the other end of the connecting block 14. The push button includes a push switch 17, a spring 18 and a fixed base 19. The fixed base 19 is in the shape of "̺" and is fixed on the connecting block 14 by screws. The push switch 17 is a structure with a profile in the shape of a capital "J". The push switch 17 is a structure in the shape of a capital "J" adapted to the width of the tooth groove 16. The lower edge of the push switch 17 is clamped on the upper edge of the fixed base 19 by a barb structure, and a spring 18 is connected between the two. When the push switch 17 is pressed, the "J" - shaped edge of the push switch 17 leaves the tooth groove 16. As Figure 5 shown, the push button can drive the connecting block 14 to slide in the strip-shaped groove 11. When the push switch 17 is released, the "J" - shaped edge of the push switch 17 is inserted into the tooth groove 16, and the push button drives the connecting block 14 to be fixed. In this embodiment, only one connecting block 14 is provided with a push button.
[0037] It should be noted that in this embodiment, the connecting block is fixed by the push switch being clamped in the tooth groove. When other methods can be used to fix the connecting block, they are all within the scope of the description of this embodiment.
[0038] Another point that needs to be pointed out is that in this embodiment, only one connecting block is provided with a push button. When two connecting blocks are provided with push buttons, or when three connecting blocks are provided with push buttons, they are all within the scope of the description of this embodiment.
[0039] Threads are provided at both ends of the fixed shaft 7. One end of the fixed shaft 7 passes through the hole in the first support plate 3 and is fixed by a retaining piece and a nut matching the thread. The other end of the fixed shaft 7 passes through the central holes 10 of the first fixing plate 8 and the second fixing plate 9, and a retaining piece and a nut matching the thread are installed to prevent the first fixing plate 8 and the second fixing plate 9 from sliding out of the fixed shaft 7.
[0040] The top of the second support plate 4 is in an inverted "L" shape towards the first support plate 3, which can fix the cut tape for convenient picking. A first blade 5 is provided on the upper side of the second support plate 4. The first blade 5 is fixed to the second support plate 4 by screws 6, and the cutting edge of the first blade 5 is higher than the second support plate 4. A rotating shaft 21 is fixedly arranged on the right side of the first blade 5. A blade protection sleeve 20 is rotatably arranged on the second support plate 4 through the rotating shaft 21. A second blade 22 is installed on the blade protection sleeve 20. The second blade 22 is parallel to the first blade 5, and the cutting edge of the second blade 22 faces away from the first blade 5. As shown in the figure, the blade protection sleeve 20 can drive the second blade 22 to rotate 360° around the rotating shaft 21. When the tape used is double-sided tape and it is inconvenient to cut with the first blade 5, the blade protection sleeve 20 can be rotated counterclockwise to drive the second blade 22 to rotate for cutting the double-sided tape.
[0041] When using this embodiment, at the beginning, all three fixing rods 13 are located at the position closest to the central hole 10 in the strip-shaped groove 11. The three fixing rods 13 form an equilateral triangle. The inner diameter of the tape is sleeved on the three fixing rods. The pressing switch 17 is pressed, and the push button is pushed to move the connecting block 14 along the strip-shaped groove 11 in the direction farther from the central hole 10. When the three fixing rods 13 can fix the tape, the pressing switch 17 is released, and the "J"-shaped edge of the pressing switch 17 is caught in the tooth groove 16 to fix the connecting block 14 and the fixing rods 13. At this time, the tape can be pulled for cutting.
