Pulling the pull ring 4 causes the sliding rod 2 to slide, while the first spring 3 retracts outward. Pull the tilting block 7 to remove the blade 8, then insert the tilting block 7 of the new blade 8 into the rectangular slot 6. Because the limiting block 5 has an inclined angle on the side near the tilting block 7, the tilting block 7 can push the limiting block 5 upward. Then, due to the tension of the first spring 3, the limiting block 5 returns to its original position, thus limiting the tilting block 7 and fixing its position. This completes the replacement of the blade 8. The connecting block 14 is fixed in the circular slot 9 due to the tension of the second spring 13. In the slot of the part, the circular slot 9 limits the rotating rod 10, which can fix the handle 11 for operation. When not in use, rotate the handle 11 to make the connecting block 14 disengage from the slot inside the circular slot 9. When the handle 11 is rotated to a certain angle, the adjusting block 15 is inserted into the adjusting slot. At the same time, the adjusting slot limits the adjusting block 15, fixing the adjusting block 15 in the adjusting slot and fixing the handle 11. In this way, the handle 11 can be folded as a whole to reduce the space occupied.

[0023] The circular slot 9 has a connecting slot 16 inside. The connecting block 14 fits into the connecting slot 16. When the connecting block 14 is inserted into the connecting slot 16, the connecting slot 16 limits the connecting block 14, so that the connecting block 14 is fixed inside the connecting slot 16, thereby fixing the angle of the rotating rod 10.

[0024] The top of the blade 8 is provided with a connecting groove, and a T-shaped slider 17 is fixedly connected inside the connecting groove. The T-shaped slider 17 is fixed by the connecting groove, and the T-shaped slider can limit the movement of the blade 8.

[0025] The bottom of the fixed plate 1 is provided with a T-shaped groove 18, and the T-shaped slider 17 fits into the T-shaped groove 18. When the T-shaped slider 17 slides into the T-shaped groove 18, the T-shaped groove 18 limits the T-shaped slider 17 to prevent the T-shaped slider 17 and the blade 8 from shifting positions.

[0026] One end of the first spring 3 is fixedly connected with the inner top wall of the rectangular clamping groove 6, and the other end of the first spring 3 is fixedly connected with the top of the limiting block 5, so that the limiting block 5 can be moved along with the first spring 3 through the connection of the first spring 3 with the rectangular clamping groove 6 and the limiting block 5 in the fixed plate 1;

[0027] One end of the second spring 13 is fixedly connected with the bottom of the connecting clamping block 14, and the other end of the second spring 13 is fixedly connected with one side of the surface of the rotating rod 10, so that the rotating rod 10 supports and fixes one end of the second spring 13 through the connection between the second spring 13 and the connecting clamping block 14 and the rotating rod 10, and the connecting clamping block 14 can be moved along with the second spring 13 when the second spring 13 is stretched or contracted.
