The axial direction of the cylindrical member 28 supported by the two bearing holes 20 is substantially parallel to the longitudinal direction of the rack gear 7, the worm wheel 26 is the worm 21, and the pinion gear 29 attached to the lower end of the ordinate 27 is the aforementioned The rack gears 7 are set to mesh with each other. A holder 23 having a plurality of needle-like bodies 24 is attached to the rotating shaft 22 on the side facing the center pipe 3, and a handle 25 is attached to the other end.
[0008]
In FIG. 3, which is an exploded perspective view around the switching lever 30, the switching lever 30 has a substantially L-shaped planar shape with three portions of the longest arm portion 31, the middle arm portion 34 and the shortest arm portion 36, and is thick. It has a thickness. A pressing protrusion 32 is formed on the front side of the end of the longest arm portion 31, a protrusion 33 for locking one end of the torsion spring 40 is formed on the back side, and an inner surface of the intermediate arm portion 34 is formed on the inner side surface. A hook-shaped engagement portion 35 that engages the longitudinal axis 27 is formed. Although not visible in FIGS. 1 and 2, a seat 19 is formed on the upper surface of the base portion 11. After the vertical axis 27 is engaged with the hook-shaped engaging portion 35, the shortest arm portion 36 of the switching lever 30 is placed on the seat 19 and attached to the position indicated by the reference numeral 37, and the leg of the slide unit 10. The three sides of the portion 12 are surrounded by an L-shaped switching lever 30. In the mounted state, the lower surface of the switching lever 30 is made higher than the guide upper surfaces 1a and 1a on both sides of the base 1 so that the switching lever 30 can be smoothly rotated around the mounting location 37. Reference numeral 17 denotes a notch that prevents the pinion gear 29 from hitting the side wall of the base portion 11.
[0009]
As apparent from FIG. 5, the torsion spring 40 having one end locked to the protrusion 33 is attached so that the other end 41 abuts the side surface of the leg portion 12. As a result, the switching lever 30 is rotated counterclockwise in the figure with the pivot point 37 as the center of rotation by the repulsive force of the torsion spring 40, so that the cylindrical member 28 at the upper end is supported by the bearing hole 20, In the vicinity of the pinion gear 29, the vertical axis 27 engaged with the hook-shaped engagement portion 35 is pushed outward, and the pinion gear 29 releases the meshing with the rack gear 7. FIG. 4B shows this state. When the user applies a force in the direction of the arrow to the pressing protrusion 32 against the spring force of the torsion spring 40 and rotates the switching lever 30 in the clockwise direction, the hook-shaped engaging portion in the vicinity of the pinion gear 29 A strong pressing force is applied to the vertical axis 27 portion engaged with 35 by the principle of scissors. FIG. 4A shows this state.
[0010]
Returning to FIG. 2 again, the side walls of the base portion 11 of the slide unit 10 are provided with notches 15 and 15 through which the rack gear 7 provided on the base plate 1 is passed, and one of the base portions 11 is provided. A notch 16 is formed on the side wall of the stopper 9 to allow the protrusion 9a of the stopper 9 to pass therethrough. When the slide unit 10 is assembled to the base 1, if the slide unit 10 is slid with the notch 15 aligned with the rack gear 7 and the notch 16 aligned with the protrusion 9 a of the stopper 9, the protrusion 9 a It can be advanced to a position where it abuts against the other side wall of the base portion 11. After that, the slide unit 10 is pushed in strongly, and the pushing force can be converted into a pressing force by the curved contact surface of the projection 9a so that the projection 9a can be pulled in. Therefore, the side wall portion can also be passed. After passing, the protrusion 9a protrudes again from the through hole 8 due to the self-repulsive force of the stopper 9, but this time, the vertical contact surface of the protrusion 9a works to prevent the base portion 11 from coming out. Even if the slide unit 10 is tilted carelessly, the slide unit 10 can be prevented from sliding down. In this example, when the slide unit 10 is brought close to the wall 2 side to the upper limit value on the upper surface of the base portion 11, it collides with the lower end portion of the wall body 2 and cannot be further advanced. 18 is formed. Therefore, the slide unit 10 can be prevented from colliding with the center pipe 3, the comb blade 4, and the flat blade 5 of the wall 2.
[0011]
The usage of this trimmer will be explained. For example, a radish that is a work to be cut is cut into a length of about 12 cm, the center portion of one end face of the radish is pierced into the center pipe 3, and the other end face is inserted. After piercing and holding with a plurality of needles 24 of the holder 23, the left index finger is applied to the left side of the leg portion 12 of the slide unit 10, and the left thumb is applied to the right side of the protrusion 32 of the switching lever 30. And a pinching pressure is applied against the force of the torsion spring 40 with both fingers. Then, the switching lever 30 rotates clockwise around the pivot point 37 and a strong force is applied to the hook-shaped engaging portion 35 engaged with the vertical axis 27 according to the principle of the hook. 4A, if the handle 25 is rotated with the right hand in this state, automatic feeding can be performed simultaneously with the cutting with the comb blade 4 and the flat blade 5. Since the vertical axis 27 portion in the vicinity of the pinion gear 29 is firmly pressed, the pinion gear 29 does not escape. When the left hand is released, as shown in FIG. 4 (b), the engagement is released by the force of the torsion spring 40, and manual feeding is enabled.
