[0024] The fixing rod assembly 2 includes a rotating shaft 5 rotatably connected to the inside of the mounting groove 102, the upper end surface of the rotating shaft 5 is fixedly connected with a locking column 6, the outer end surface of the locking column 6 is provided with a plurality of abutting grooves 601, the inner side of the abutting grooves 601 is slidably connected with a locking block 7, the inner side of the locking column 6 is movably plugged with a mounting rod 8, the outer end surface of the mounting rod 8 is fixedly connected with a plurality of guide rods 801, the outer end surface of the guide rod 801 is sleeved with an elastic member 9, the elastic member 9 elastically abuts the locking block 7 to move outward, when the dental floss roll is sleeved on the fixing rod assembly 2, the locking block 7 moves along the abutting groove 601 to the inside of the locking column 6, so that the elastic member 9 is compressed and the abutting locking block 7 moves outward, so that the inner wall of the dental floss roll is fixed by friction with the locking block 7 and cannot be easily pulled out, which facilitates the fixing of the dental floss roll, and the dental floss roll can be replaced by simply pulling out and plugging, thereby improving the detection efficiency of the device.

[0025] The inner end face of the positioning block 7 is fixedly connected to the limiting strip 701, and the limiting strip 701 movably abuts against the inner wall of the positioning column 6. A guide rod groove 703 cooperating with the guide rod 801 is provided inside the positioning block 7. The positioning block 7 can be fixed by the limiting strip 701 to prevent it from escaping from the abutting groove 601 outward. When the positioning block 7 moves to the inside of the positioning column 6, the guide rod 801 can be inserted into the guide rod groove 703 to improve the stability of the device.

[0026] The top of the positioning block 7 is provided with an inserting chamfer 702, and the inserting chamfer 702 can facilitate the insertion of the dental floss roll.

[0027] The upper opening of the locking column 6 is fixedly connected to a top plate 10 by means of screws, and the lower end surface of the top plate 10 is fixedly connected to an abutment column 11, and the bottom of the abutment column 11 movably abuts the top of the mounting rod 8.

The dental floss roll can be replaced by simply plugging and unplugging, thereby improving the detection efficiency of the device. Then, the dental floss to be tested is passed through the support column 4 and wound around the empty dental floss roll. The motor 13 drives the screw rod 12 to rotate, driving the sliding block 3 and the support plate 301 to move.
