Then, a new emergency stop block 28 is installed and buckled, and the fastening screw 27 is tightened. When the baffle 18 needs to be replaced, the fastening rod 24 is rotated to screw out the end of the fastening rod 24 from below the baffle 18, and then the baffle 18 is pulled outwards to remove the damaged baffle 18. Then, a new baffle 18 is buckled again and the end of the fastening rod 24 is screwed into the hole slot at the lower end of the baffle 18. Through this method, when the baffle 18 and the emergency stop block 28 are damaged and cannot ensure the emergency stop effect, they can be replaced in time, ensuring the smooth implementation of the emergency stop device function.

[0036] Working principle: When the device is in use, when the sensors 21 on both sides of the support frame 2 sense that the worker's hand is under the blade 3, the first electric push rod 13 will start quickly and push the connecting piece 12 downwards. When the connecting piece 12 moves downwards, the ends of the connecting rods 11 on both sides of the connecting piece 12 will move to both sides respectively, and push the two sliding blocks 10 to move to both sides. After the sliding blocks 10 move, the bent rods 15 connected to the sliding blocks 10 will be stressed and rotate around the connection point between the fixed rod 16 and the support frame 2 as the center. When the bent rod 15 rotates, the other end of the bent rod 15 will push the rotating block 17 to rotate, and the emergency stop block 28 on the side of the rotating block 17 will rotate from an inclined angle to a horizontal angle. When the two emergency stop blocks 28 are in a horizontal state, the buckles on the emergency stop blocks 28 will be buckled with the blocking teeth 25 on the baffle 18 to block the blade 3 from continuing to move. When the emergency stop block 28 needs to be replaced, the fastening screw 27 can be removed, and then the emergency stop block 28 is pulled outwards to pull out the buckle blocks 29 on both sides from the buckle slots 26. Then, a new emergency stop block 28 is installed and buckled, and the fastening screw 27 is tightened. When the baffle 18 needs to be replaced, the fastening rod 24 is rotated to screw out the end of the fastening rod 24 from below the baffle 18, and then the baffle 18 is pulled outwards to remove the damaged baffle 18.
