When the transferring frame is placed on the steel strip, the elastic members at each vacuum chuck 2 are forced to compress under the weight of the transferring frame, so that the vacuum chucks 2 move close to the transferring frame. For the completely deformed part on the steel strip, the moving amount of the vacuum chucks 2 relative to the transferring frame is different, so that each vacuum chuck 2 can accurately contact the steel strip, thereby using the plurality of vacuum chucks 2 to multi-point adsorb the steel strip, and improving the adsorption and fixing effect on the steel strip.

[0020] Specifically, the elastic member can be a spring 22, the transferring frame is provided with a connecting sleeve 3, the connecting column 21 is vertically and slidingly arranged in the connecting sleeve 3, two springs 22 are sleeved on the connecting column 21, the two springs 22 are respectively located on the two sides of the connecting sleeve 3, and one end of the spring 22 is connected with the connecting column 21 and the other end is elastically abuts against the connecting sleeve 3. By arranging the spring 22 on the two sides of the connecting sleeve 3, under the common action of the elastic forces of the two springs 22, the connecting column 21 can be slidingly centered and reset in the connecting sleeve 3, the elastic force that can be applied by the spring 22 is increased, and the service life of the spring 22 is prolonged.

[0021] Further, the bottom end of the connecting column 21 is ball-hinged with the vacuum chuck 2.
