By adjusting the working position of the clamping plate 4514, it is convenient for the installation of the machine tool window.

[0042] In an embodiment of the present invention, as Figure 2 、 Figure 3 and Figure 7 shown, the second window fixing member 46 may include: a plurality of second electric telescopic rods 461 and a plurality of electric control suction cups 462.
