The space between the active roller 3 and the driven roller 13 is the space for the glove to be squeezed into. The workbench 1 is provided with a driving component for driving the active roller 3 to rotate, and the workbench 1 is provided with a moving component for driving the driven roller 13 to move. The moving component adjusts the height of the driven roller 13 when it works, thereby adjusting the distance between the active roller 3 and the driven roller 13.

[0025] When in use, the cotton-filled glove is brought close to the active roller 3 and the driven roller 13, and the driving component works to rotate the active roller 3, thereby bringing the glove into the space between the active roller 3 and the driven roller 13 to cause squeezing, thereby implementing safety education. The height of the driven roller 13 is adjusted by the moving mechanism, and then the distance between the driven roller 13 and the active roller 3 is adjusted, thereby facilitating the demonstration of the damage to the palm caused by squeezing spaces of different sizes, and having higher practicality.

[0026] Specifically, refer to Figure 1A first rotating shaft 4 is provided on both sides of the active roller 3, and a first bearing seat 2 is provided on the workbench 1.

A second rotating shaft 12 is provided on both sides of the driven roller 13, and a second bearing seat 11 is provided on the workbench 1. The second rotating shaft 12 is connected to the second bearing seat 11, and the stable rotation of the driven roller 13 on the workbench 1 is achieved through the second bearing seat 11 and the second rotating shaft 12. In this embodiment, there are two first bearing seats 2 and two second bearing seats 12, and bearings are provided in the first bearing seat 2 and the second bearing seat 12.

[0027] Sponge pads 14 are provided on the active roller 3 and the driven roller 13 to increase the friction between the active roller 3 and the driven roller 13, thereby facilitating the movement of the glove between the active roller 3 and the driven roller 13 for squeezing.

[0028] The driving assembly includes a motor 5, a driving pulley 6, a belt 7 and a driven pulley 8. The motor 5 is connected to the workbench 1, the power output shaft of the motor 5 is connected to the driving pulley 6, the driven pulley 8 is connected to the first rotating shaft 4, and the driving pulley 6 is connected to the driven pulley 8 through the belt 7. When the motor 5 works, the power output shaft of the motor 5 rotates to drive the driving pulley 6 to rotate, the rotation of the driving pulley 6 causes the belt 7 to move, and the movement of the belt 7 causes the driven pulley 8 to rotate. The rotation of the driven pulley 8 causes the first rotating shaft 4 to rotate, thereby causing the active roller 3 to rotate. Specifically, the motor 5 is connected to the work platform 1 through bolts, the power output shaft of the motor 5 is connected to the driving pulley 6 through a coupling, and the first rotating shaft 4 is connected to the driven pulley 8 through a coupling.
