[0012] Preferably, the tensioning mechanism includes a through groove, a plurality of through grooves of equal arc are provided on the outer wall of the drum, a splint is movably installed inside the through groove, both inner ends of the splint are movably connected to the drum through a spring, a cone is movably installed in the middle of the drum, the outer wall surface of the cone matches the inner end surface of the splint, a screw rod 2 is threadedly connected in the middle of the movable column, the left end of the screw rod 2 is fixedly connected to the cone, and the right end of the screw rod 2 is fixedly connected to the knob 2;

[0013] Preferably, a guide groove is provided in an annular shape inside the bottom end of the bracket, and a guide ring matching the guide groove is provided on the middle outer wall of the movable column.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This tape cutting device, when installing, put the sleeve on the inner side of the tape on the roller, then hold the support block with your left hand, and rotate the second knob with your right hand. The second knob drives the cone to rotate and extend into the inside of the roller, and pushes several splints outward. The splints are clamped in reverse from the inner wall of the sleeve, so that it can be installed in a compatible manner with the tape, thereby preventing it from being lost during use. It can also be quickly disassembled when not in use.

[0016] 2. This tape cutting device, when this device is adapted and installed with the tape, adjust the position of the cutter head according to the thickness of the tape. When adjusting, twist knob one, and knob one drives screw one to rotate and descend. The arc plate is guided by the guide rod and guide groove to descend straightly, and the cutter head abuts against the outer wall of the tape. When cutting, pinch the end of the tape and pull it outward until the required length is pulled out, then stop and tear along the abutment between the tape and the cutter head. In this way, the tape will be quickly cut by the blade of the cutter head. This can be adapted to tapes of different thicknesses for use. BRIEF DESCRIPTION OF THE DRAWINGS
