Furthermore, as shown in FIGS. 1, 2, and 3, a rectangular through groove is specifically formed on the outer surface of the handle 1, and the dimension of the rectangular through groove is larger than the diameter of the spring 7.

Furthermore, as shown in FIG. 1, FIG. 2 and FIG. 3, specifically, an anti-slip sleeve 4 is attached to the outer surface below the handle 1, and the material of the anti-slip sleeve 4 can be a rubber layer.

The anti-slip sleeve 4 can increase the friction between the user and the handle 1, increase the stability when using the device, avoid slipping of the device due to sweat, and increase the practicality of the device.

1, 2 and 3, the operation mechanism 9 specifically includes a connecting vertical shaft 901, a driven gear 902, a driving bevel gear 903, a connecting horizontal shaft 904, a switch 905, a disk 906, a circular hole 907 and a magnet 908. The connecting vertical shaft 901 is rotatably connected to the inner bottom surface of the handle 1. The driven gear 902 is fixedly connected to the center of the connecting vertical shaft 901. A driving bevel gear 903 is provided above the driven gear 902. The driving bevel gear 903 is engaged with the driven gear 902. The connecting horizontal shaft 904 is connected to the tip of the driving bevel gear 903.
4 is fixedly connected to the connecting horizontal shaft 904, and a switch 905 is fixedly connected to the tip of the connecting horizontal shaft 904.
The switch 905 is pivotally connected to the handle 1 .

The switch 905 rotates the connecting horizontal shaft 904, and the connecting horizontal shaft 904 drives the bevel wheel 9.
03 to rotate the driven gear 902, and then rotate the upper and lower disks 906 to adjust the positional relationship between the circular hole 907 and the magnet 908.

As can be seen from the above operation process, the disk 906 is connected to the magnet 9 by the installed operating mechanism 9.
The presence or absence of magnetism in the magnet 908 is controlled by closing the north and south poles of the magnet 908, and the movement of the sickle 2 is further controlled to cut the object. The structure of the device is simple and easy to operate, which can increase the practicality of the device.

Furthermore, as shown in Figures 2, 3 and 4, specifically, a disk 906 is fixedly connected to both ends of the connecting vertical shaft 901, and a circular hole 907 is opened at a position away from the center of the disk 906, and the disk 906 can be made of non-magnetic brass.

The south and north poles of 08 coincide with the direction of the handle 1, and the disc 906 controls whether or not the magnet 908 is magnetic by closing the south and north poles.

The working process of this technical solution is as follows: when in use, turn the switch 905 to open the device, rotate the driving bevel gear 903 through the connecting horizontal shaft 904, rotate the connecting vertical shaft 901 through the driven bevel gear 902, and rotate the upper and lower disks 906 at the same time, so that the circular hole 907 overlaps with the south pole and north pole of the magnet 908.
908 attracts the magnetic metal plate 8, moving the magnetic metal plate 8 and rotating the sickle 2 through the rotating shaft 3, putting the sickle 2 into a tensioned state. Then, the switch 905 is turned in the opposite direction to close the device, and the disk 906 closes the south and north poles of the magnet 908, causing the magnet 908 to lose its external magnetism and no longer attract the magnetic metal plate 8. This causes the magnetic metal plate 8 to slide upwards rapidly, moving the sickle 2 rapidly, further cutting the object and improving the cutting efficiency.

As described above, by using the installed operating mechanism 9, the disk 906 closes the north and south poles of the magnet 908 to control the presence or absence of magnetism in the magnet 908, and further controls the movement of the sickle 2 to cut the object.
