[0029] In combination with Figure 3 , attached Figure 7 and attached Figure 8, the permanent magnet two 20 can be just aligned with the permanent magnet one 19, and the two attract each other to achieve the locking effect of the linear module 4. When it is needed to open the linear module 4 to remove the ultrasonic coupling agent 10 of the toothpaste tube, the permanent magnet one 19 and the permanent magnet two 20 can be dislocated by manually pushing the slider 5, so as to release the locking and make the linear module 4 freely flip.
