When the distance between the first clamping assembly 31 and the second clamping assembly 32 is not matched with the size of the material III 8, the distance between the first clamping assembly 31 and the second clamping assembly 32 needs to be adjusted by the adjusting mechanism 5 to adapt to the material III 8 with various specifications and sizes. The specific adjustment mode is that, rotating disc 52 is rotated, rotating disc 52 drives transmission rod 51 to rotate, thereby driving mounting seat 4 to move, and then since mounting seat 4 is installed on slider 55, transmission rod 51 drives mounting seat 4 to move along guide rail 53, namely, in the left-right direction, so as to be close to or away from another mounting seat 4, first clamping component 31 and second clamping component 32 are respectively installed on two mounting seats 4, thereby first clamping component 31 and second clamping component 32 on mounting seat 4 and mounting seat 4 are also close to or away from each other. The clamping device has stronger adaptability by arranging the adjusting mechanism 5, can be suitable for clamping materials with various sizes, and is more flexible to use. The rotary disc 52 can be rotated by hand or by a motor. The adjusting mechanism 5 may be provided on one of the mounting seats 4, but of course, the adjusting mechanism 5 may be provided on each of the mounting seats 4. The detachable mode of this scheme can be bolt, buckle etc.
