As shown in Fig. 7 (a), pass through rake 32c and the abutting of pin 33 and the bottom surface of abutting part 32f, 32g and slot 31b Cutlery 32 is located in holder in the direction (perpendicular to the direction of left and right directions) in the face for being parallel to cutlery 32 by 311 abutting 31.In addition, cutlery 32 is pressed against by the side for pressing cutlery 32 using pressing component 34 by the medial surface on the right side of slot 31b, And cutlery 32 is located in holder 31 at the direction in the face perpendicular to cutlery 32 (left and right directions).Therefore, cutlery 32 can It certainly positions in face direction and perpendicular to the direction in face.At this point, because cutlery 32 by the abutting of rake 32c and pin 33 with And the bottom surface 311 of abutting part 32f, 32g and slot 31b abutting and position in face direction, so will not generate as patent text Make pin through hole documented by offering in 1 and positions and shaken as the composition of cutlery.It as a result, according to the present embodiment, can be true Cutlery 32 is mounted on holder 31 on the spot.

In addition, in the present embodiment, rake 32c is tilted as follows: being applied to cutlery 32 when cutoff action Power plays the effect of the power in the direction as the bottom surface 311 that abutting part 32f, 32g are pressed against to slot 31b.That is, such as Fig. 7 (a) shown in, point of a knife 32b is in cutoff action, by the power in upper direction and the power of rear direction.Because of these power, cutlery 32 is by general Rake 32c is pressed against pin 33 and abutting part 32f, 32g is pressed against to the effect of the bottom surface 311 of slot 31b.Therefore, though ten thousand The pressing relaxation of one pressing component 34 and so that cutlery 32 is become the state that can be subjected to displacement, via point of a knife when also can be because of cutoff action 32b is applied to the power of cutlery 32, and rake 32c is pressed against pin 33 on one side, and abutting part 32f, 32g are pressed against slot on one side The bottom surface 311 of 31b, makes cutlery 32 be located in conventional position, to be properly maintained the angle of film member F Yu point of a knife 32a. Thereby, it is possible to properly carry out cutoff action.

In addition, as shown in Fig. 7 (a), cutlery 32 the position for being connected to pin 33 of rake 32c upside with rake 32c connected mode has supporting part 32d.As a result, in the case where relieving the pressing of pressing component 34 for some reason, As shown in Fig. 7 (b), also pin 33 can be made to be fastened on supporting part 32d, so that abutting part 32f is connected to the bottom surface 311 of slot 31b, thus press down Only cutlery 32 falls off from holder 31.

In addition, as shown in Fig. 7 (a), in the upper limb setting of cutlery 32, there are two abutting part 32f, 32g, make the two abuttings Both portion 32f, 32g are connected to the bottom surface 311 of slot 31b, thus position cutlery 32.So two abutting parts 32f, 32g is made to exist In the case where being contacted at two with bottom surface 311, even if there are some fluctuatings for the bottom surface 311 of slot 31b, be also easy to make abutting part 32f, 32g without shaking is connected to the bottom surface 311 of slot 31b.

For example it is assumed that following situation: omitting recess portion 32e, the upper of cutlery 32 is linearly arranged in an abutting part Edge simultaneously makes abutting part be connected to the bottom surface 311 of slot 31b.In this case, for example, if the bottom surface 311 of slot 31b is in length side To center nearby slightly swell, then in the case where abutting part is pressed against bottom surface 311, abutting part can be led to because of protuberance The either end of length direction become the state that suspends from bottom surface 311, cutlery 32 is easy to produce the shaking in face direction.Relative to This, in said embodiment, because there are two abutting part 32f, 32g for setting, even if the bottom surface 311 of slot 31b is in length The center in direction is nearby slightly swelled, and both two abutting parts 32f, 32g also can be properly pressed against to the bottom surface 311 of slot 31b. Therefore, the specific position that can be more reliably located in cutlery 32 in slot 31b.

In addition, in the present embodiment, as shown in Fig. 3 (a), (b), two abutting parts 32f, 32g pass through respectively to be chamfered At arc-shaped, and make in the front-back direction width narrow with towards front end.Thereby, it is possible to reduce abutting part 32f, 32g to slot 31b Bottom surface 311 contact area, and make abutting part 32f, 32g be not easily susceptible to slot 31b bottom surface 311 fluctuating influence.Therefore, Become easy the bottom surface 311 for making abutting part 32f, 32g there are no shaking be connected to slot 31b.

In this way, in order to make abutting part 32f, 32g there are no shaking be connected to the bottom surface 311 of slot 31b, it is generally desirable to as far as possible Reduce the width in the front-back direction of the upper surface of abutting part 32f, 32g.For example, abutting part can also be omitted as shown in Fig. 8 (a) The upper surface of 32f, 32g only retain the crest line of left and right directions in the upper end of abutting part 32f, 32g.In this way, because abutting part 32f, 32g are contacted with 311 line of bottom surface of slot 31b respectively, so abutting part 32f, 32g can be made further without shaking to abut In the bottom surface of slot 31b 311.In addition, abutting part 32f, 32g are also possible to spherical surface.In this way, which abutting part 32f, 32g can be made Respectively with 311 point contact of bottom surface of slot 31b, abutting part 32f, 32g can be made further without shaking to be connected to the bottom surface of slot 31b 311。

In addition, in the present embodiment, being configured to as shown in Figure 2, spherical pressing component 34 is pressed into from holder 31 Side continuously arrive the hole 31d of slot 31b, and press the side of cutlery 32, therefore can also play and can easily carry out press section The effect of the installation exercise of part 34.
