[0042] When the size of the cut steel bar changes and the blade 403 needs to be replaced, the third cylinder 402 is started to drive the blade 403 to move downward. When the blade 403 contacts the upper surface of the workbench 1, the blade 403 is fixed with a tool to prevent it from falling and accidentally injuring the operator during replacement. The limit plate 406 is then pulled outward, and the limit plate 406 moves outward to drive the bottom rod 408 and the limit rod 409 to disengage from the socket 410. The spring 407 is stretched when the limit plate 406 moves. When the limit plate 406 moves outward, the connecting rod 411 disengages from the limit hole 412, and the limit on the connecting rod 411 and the blade 403 is released. The blade 403 is then removed and replaced with a new blade 403. The limit plate 406 is released, and the connecting rod 411 is inserted into the limit hole 412 under the drive of the spring 407 to rebound, and the replacement is completed.
