[0023] Reference Figure 2-Figure 5A placement groove 4 is provided on the back of the fixed frame 3, a transparent film 5 is provided in the placement groove 4, and the back of the transparent film 5 is attached to the screen of the non-contact self-service touch display screen body 1, and the front of the inner cavity of the placement groove 4 and the front of the transparent film 5 are provided with a square-shaped Velcro 6 that can be bonded to each other. The bottom of the fixed frame 3 is symmetrically fixed with vertical plates 9 along the left and right directions. A T-shaped plate 10 is inserted on each set of vertical plates 9 and the top of the T-shaped plate 10 is attached to the bottom of the non-contact self-service touch display screen body 1. Both sides of each set of vertical plates 9 are fixed with a first spring 11 through a support plate and one end of the first spring 11 is fixed to the protruding end of the T-shaped plate 10 , a positioning frame 13 is inserted on the back of the bottom of each group of T-shaped plates 10, and a strip groove 17 is opened on the back of the top of the T-shaped plate 10 for use with the positioning frame 13. An annular pull plate is fixed to the front of the T-shaped plate 10 and the bottom of the positioning frame 13. The design of the strip groove 17 can hide the positioning frame 13 to prevent the positioning frame 13 from affecting the normal movement of the T-shaped plate 10, and the design of the annular pull plate makes it easy for the user to move the T-shaped plate 10 and the positioning frame 13. A positioning groove 15 is opened at the bottom of the contactless self-service touch display screen body 1 for use with the positioning frame 13. A second spring 14 is wound around each group of positioning frames 13 and the first spring 15 is wound around each group of positioning frames 13. The two ends of the second spring 14 are fixed to the bottom of the T-shaped plate 10 and the bottom of the positioning frame 13.
