[0014] When the detection device detects the tearing force of the cloth, the end of the cloth can be wound around the winding drum 1, and the end of the cloth will be interlaced with the winding drum 2. After the winding drums 1 and 2 wind the cloth, the driving rod is driven by the motor 3 to rotate. Since the bevel gear 4 is meshed with the bevel gear 3, and the bevel gear 1 is meshed with the bevel gear 2, the driving rod and the threaded rod 2 will rotate synchronously, and the moving plate will slide on the surface of the threaded rod 2.

[0019] 2. The present invention sets an adjustment structure, and the motor three drives the driving rod to rotate. The driving rod and the threaded rod two will rotate synchronously, and the movable plate will slide on the surface of the threaded rod two.

The rubber plate 1 (705) and the rubber plate 2 (706) will rotate in opposite directions and synchronously, so as to clamp the cloth wound in the winding drum 1 (13) and the winding drum 2 (14) at the same time; The threaded rod (4) is driven to rotate by the motor (5), and the detection plate (6) moves on the surface of the threaded rod (4). After the detection plate (6) moves on the surface of the fixed column (10), the clamped cloth is torn, and the sensor built into the adjustment structure (9) transmits the data of the tearing force to the display (2). When the connecting plate (11) moves, the limit block (803) on the surface of the positioning rod (17) slides in the limit groove (802), and the rotating rod (904) also slides in the rotating drum (903).
