The above is the configuration description of the main components of the embodiment of the present invention. As for the operation mode and effect of the present invention, the description is as follows:

First, improve the balance, stability and accuracy of cutting. Referring to FIGS. 4A, 4B and 5, since the first blade 42 and the second blade 52 used in the present invention are both hollow cone-cylinder blades, the present invention is particularly useful for the first blade 42 and the second blade There are two first bearings 43 and two second bearings 53 in each of 52. The double bearing design enables the first blade 42 and the second blade 52 to prevent unilateral inclination during the cutting process, and at the same time It can bear the load acting on each blade during cutting and maintain the cutting position of each blade, effectively improving the balance, stability and accuracy of the cutting of the two blades.

Second, it can be used for left-hand or right-hand holding to improve applicability. 1 and 6, when the handle assembly hole 612 of the handle connecting piece 61 of the holding unit 60 is located on the right side of the adjustment portion 112 of the body 11, the handle assembly portion of the handle 62 After the group 622 is provided in the handle assembly hole 612 on the right side, it is held by a right-handed user for cutting operations. Referring to Figures 6 and 8, when a left-handed user holds and performs cutting operations, the user can detach the top cover 63, and then replace the handle connecting piece 61 to assemble it, that is, the The handle assembly hole 612 is exchanged to the left side of the adjusting portion 112 of the main body 11. At this time, the handle 62 is located on the left side of the main body 11 and can be held by left-handed users for cutting operations. It can be seen that the present invention can change the positions of the handles 62 on the left and right sides of the main body 11 as required, so as to be held and used by users with different dominant hands, which indeed effectively improves the applicability.

Third, the cutting thickness can be adjusted. Referring to FIGS. 2, 5, 6 and 9, when the cutting thickness is to be adjusted, the thickness positioning button 24 is first unscrewed to release the trapezoidal block 22 from the longitudinal adjustment groove 114 of the main body 11. , Then push the pivot portion 211 of the blade adjustment button 21, so that the blade adjustment button 21 not only pivots in place, it also drives the blade adjustment screw 23 to rotate, and the trapezoidal block 22 can only be used in the body The longitudinal adjustment slot 114 of 11 is displaced up and down and cannot be rotated. Therefore, the rotating blade adjustment screw 21 will drive the trapezoidal block 22 to move up and down along the longitudinal adjustment slot 114, thereby driving the second blade 52 on the trapezoidal block 22 Synchronize up and down displacement, and also change the longitudinal distance between the first blade 421 of the first blade 42 and the second blade 521 of the second blade 52 in order to achieve the effect of adjusting the cutting thickness (the state is shown in Figure 10 ). After the cutting thickness is adjusted, the thickness positioning button 24 is tightened so that the trapezoidal block 22 is in a fixed state for cutting operation.

Fourth, the cutting width can be adjusted. Referring to Figure 2, Figure 5, Figure 7, Figure 11 and Figure 12, when the cutting width is to be adjusted, the width positioning button 36 is loosened to release the sliding seat 33 from the seat 111 of the body 11. For adjustment, the width positioning button 36 is tightened after adjustment, so that the sliding seat 33 is fixed to the seat 111 of the main body 11 for cutting operation. The sliding seat 33 can be adjusted coarsely and finely, respectively, as described below. Of course, in the process of adjustment, a scale may be provided on one side of the seat 111 of the main body 11 so as to know the width of the cut.

Coarse adjustment: Refer to Figure 11 and Figure 12, press the quick release block 351 upward to separate the engagement portion 3511 of the quick release block 351 from the threaded portion 311 of the slide adjustment screw 31, so that the quick release group 35 In the coarse adjustment position, the sliding seat 33 can be quickly moved back and forth to a predetermined position, and the cutting guide plate 34 fixed on the sliding seat 33 can also be moved to the predetermined position. Then the quick-release block 351 is released. At this time, the quick-release block 351 is pushed down by the quick-release spring 352, so that the engaging portion 3511 of the quick-release block 351 and the threaded portion 311 of the sliding seat adjustment screw 31 mutually interact. Engaged (the state is shown in FIG. 7), the quick release group 35 is in the fine adjustment position, at this time, the sliding seat 33 can no longer be quickly moved back and forth.

Fine adjustment: Refer to Figures 5 and 7, when the quick release group 35 is in the state of fine adjustment position, the screw adjusting button 32 is rotated to drive the sliding seat adjustment screw 31 to pivot in place, and because the quick release group 35 35 in the state of fine adjustment position, the engaging portion 3511 of the quick release block 351 is meshed with the threaded portion 311 of the slide adjustment screw 31, and the quick release set 35 is assembled on the slide 33, thus driving The sliding seat 33 moves forward and backward in the pitch amplitude along the axial direction of the sliding seat adjusting screw 31 to realize the function of fine adjustment of the sliding seat 33.

In summary, the above-mentioned embodiments and drawings are only preferred embodiments of the present invention. When they cannot be used to limit the scope of implementation of the present invention, all equivalent changes and modifications made in accordance with the scope of the patent application of the present invention shall belong to This invention patent covers the scope.
