The first section (41), the second section (411) and the third section (412) of the contraction transmission shaft 4 are respectively connected with the contraction part (2), the side rail (1) and the middle rail (3). When the anti-theft net is adjusted by windows with different sizes, the rotating handle (42) on the contraction transmission shaft (4) rotates clockwise at zero degree, the contraction transmission shaft (4) is matched and linked with the contraction part (2), so that the anti-theft net can be contracted in the Z-axis direction to reduce the size of the anti-theft net in the Z-axis direction or opened to expand the size of the anti-theft net in the Z-axis direction; the rotating handle (42) on the contraction transmission shaft (4) rotates anticlockwise at ninety degrees, the contraction transmission shaft (4) is matched and linked with the contraction piece (2), and the anti-theft net can be contracted in the X-axis direction to reduce the size of the anti-theft net in the X-axis direction or be opened to expand the size of the anti-theft net in the X-axis direction. When the anti-theft net contracts in the Z-axis direction, the middle rail (3) and the side rail (1) contract along the sleeve (16) of the side rail (1) under the interaction of the clockwise contracting part (2) and the contracting transmission shaft (4), the fixing pipe (33) on the middle rail (3) contracts, the clamping point (34) of the fixing pipe (33) is matched with the clamping groove (161) in the sleeve (16) of the side rail (1) for limiting and fixing, and the operation is performed in the opposite direction when the anti-theft net is opened and expanded. When the anti-theft net contracts in the X-axis direction, the middle rail (3) and the side rails (1) are mutually acted by the contraction transmission shaft (4) anticlockwise and the contraction part (2), each section on the side rails (1) and the middle rail (3) is close to the middle to contract under the action of the contraction part (2), and the operation is vice versa when the anti-theft net is opened and expanded. Finally, after the position of the fixing block (52) on the fixing nail (5) on the side rail (1) is adjusted, the anti-theft net is fixed through the fixing hole (51) on the fixing nail (5).
