The rotating table 2 is rotatably installed on the base 1, and the guide columns 3 are respectively installed on the base 1 on both sides of the rotating table 2. The two guide columns 3 are respectively provided with slide grooves 31 on the opposite sides. The two ends of the cutting device 4 are located in the slide grooves 31 on both sides, and the cutting device 4 can slide up and down along the slide grooves 31; the rotating table 2 is provided with a placement groove 21, a first cutting groove 22 and a second cutting groove 23, the placement groove 21 is used to place the rubber strip 5, the first cutting groove 22 is perpendicular to the placement groove 21, and the second cutting groove 23 is located between the placement groove 21 and the first cutting groove 22, and at least one pressing plate 24 is installed on the upper side of the rotating table 2, and the pressing plate 24 is used to fix the rubber strip 5 in the placement groove 21. By fixing the rubber strip 5 in the placement groove 21 of the rotating table 2 and rotating and adjusting the rotating table 2, the cutting device 4 is aligned with the first cutting groove 22 or the second cutting groove 23, so that the rubber strip can be conveniently cut at two angles.
[0028] Since the first cutting groove 22 is perpendicular to the placement groove 21, when the cutting device 4 is aligned with the first cutting groove 22, Figure 8 , the rubber strip is cut at an angle of 0 degrees. Preferably, the angle between the first cutting groove 22 and the second cutting groove 23 is 45 degrees. When the cutting device 4 is aligned with the second cutting groove 23, see Figure 8 , cut the tape at a 45 degree angle.
[0029] Preferably, the rotating table 2 is made of a tetrafluoroethylene plate.
[0030] The rotating connection between the rotating table 2 and the base 1 can be achieved by installing a central shaft at the center of the base 1, setting a central blind hole at the bottom of the rotating table 2, and inserting the central shaft into the central blind hole, so that the rotating table 2 can rotate.
[0031] In a preferred embodiment, see Figure 1 , 2 The top of the base 1 is provided with a rotation groove 11, and the rotating table 2 is placed in the rotation groove 11. The positioning and rotation of the rotating table 2 are realized by the above structure.
[0032] See also Figure 1-4 The rotating table 2 is also provided with a lug 28, and a limiting hole 281 is provided on the lug 28. The base 1 is provided with a first positioning hole 12 and a second positioning hole 13. When the positioning member 29 is installed in the limiting hole 281 and the first positioning hole 12, the second cutting groove 23 is aligned with the cutting device 4. When the positioning member 29 is installed in the limiting hole 281 and the second positioning hole 13, the first cutting groove 22 is aligned with the cutting device 4. By aligning the limiting hole 281 on the lug 28 with the first positioning hole 12 and the second positioning hole 13, the angle of the rotating table 2 can be positioned and adjusted.
[0033] Preferably, the positioning member 29 is a latch or a hand-tightened bolt.

The cutter 44 is aligned with the first cutting groove 22 or the second cutting groove 23.
[0040] When the cutting device 4 of the above two schemes is in use, the two ends of the guide plate 41 are located in the slide grooves 31 of the guide columns 3 on both sides, and the width of the guide plate 41 is adapted to the width of the slide groove 31, so that the cutting device 4 can slide up and down along the slide groove 31. When in use, hold the guide plate 41, align the guide plate 41 with the slide groove 31, and then press the guide plate 41 downward.
[0041] The action process or principle of the utility model is as follows:
[0042] When using, see Figure 1 According to the cross-sectional angle of the rubber strip 5 to be cut, the rotating table 2 is rotated, and when the limiting hole 281 on the lug 28 is aligned with the first positioning hole 12, see Figure 7 , cut a 45 degree section, when the limiting hole 281 on the lug 28 is aligned with the second positioning hole 13, see Figure 8 , cut 45 degree section.
[0043] After the position of the rotating table 2 is adjusted, the two pressing plates 24 are opened, and the rubber strip is inserted into the placement groove 21 on the rotating table 2 . Then, the spring 26 presses the pressing plate 24 to fix the rubber strip 5 in the placement groove 21 .
