The method of using the cutting assembly 4 will now be described. The pair of secondary cutting teeth 42 may be rotated either inwardly as shown in fig. 23 or outwardly as shown in fig. 24. The method of use of the cutting assembly 4 will be further described below. As shown in fig. 21 and 22, since the return spring 40 penetrates the main cutting ring gear 41 and the sub cutting ring gear 42, the sub cutting ring gear 42 always has a tendency to return regardless of whether the sub cutting ring gear 42 rotates inward or outward, so that the pair of sub cutting ring gears 42 and the main cutting ring gear 41 constitute a complete ring structure.

The following description is about the use method of the fruit tree nail opening device, comprising the following steps:

step S1, as shown in fig. 25, the user holds the handle body 21 and presses the cutting assembly 4 directly against the trunk L in the direction F1 so that the secondary cutting teeth 42 of the cutting assembly 4 directly abut against the trunk L, whereupon the pair of secondary cutting teeth 42 begin to rotate inwardly until the trunk L has completely passed through the secondary cutting teeth 42. At this point, the trunk L is in the cutting assembly 4;

step S2, manually rotate the handle 32 of the driving assembly 3 along the direction R, and the driving gear disc 31 directly drives the first rotating tooth 291, the first rotating tooth 291 drives the main shaft 28, and at the same time, the main shaft 28 drives the second rotating tooth 292. Since the second rotary teeth 292 are engaged with the teeth of the main cutting ring 41 and the teeth of the sub cutting ring 42, the whole cutting assembly 4 starts to rotate, the cutter S cuts the bark of the trunk L, and finally the circular cutting operation of the bark of the trunk L is completed. In the process of cutting, the main blade 62 functions to cut the outer skin, and the sub blade 63 functions to peel the outer skin;

at step S3, the user holds the handle body 21 and moves the cutting assembly 4 directly away from the trunk L in the direction F2, whereupon the pair of secondary cutting ring gears 42 begin to rotate outwardly until the trunk L is completely detached from the cutting assembly 4.

Because the hand-operated driving assembly is adopted, the operation is simple, the cutting is easy, and the fruit cutter is particularly suitable for fruit growers.

As shown in fig. 28 to 32, a second embodiment of the fruit tree nail cutter according to the present invention is different from the first embodiment in that a tail post screw 231 is provided on the fixed tail post 23. A pair of guide sliding grooves 221 arranged in parallel are arranged on the handle horizontal bar 22, a door-shaped abutting support 9 is arranged on the guide sliding grooves 221, a support screw hole 91 is arranged at the tail part of the abutting support 9, and the tail post screw rod 231 penetrates through the support screw hole 91 and is connected with a support nut 10.

The method for using the second embodiment of the fruit tree nail opening device is described below. As shown in fig. 32, when the cutting assembly 4 performs the circular cutting operation, the open end of the support 9 can directly support the trunk L, thereby reducing the load on the user's hand and reducing the fatigue. The extension of the support 9 can be adjusted back and forth by the support nut 10, and the operation is convenient.

As shown in fig. 33, in another embodiment of the pressing bracket 9, an arc-shaped pressing bar is arranged at the head of the pressing bracket 9, which is suitable for trunks with different outer diameters.

Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
