By this, at the driver plate 4, the leading staples in the magazine portion 3 are extracted from the punching portion 10 to penetrate the iron paper, and the leg portions of the staples that penetrate through the clincher grooves 6 of the base 1 are formed. It can be bent and ironed.

In addition, resin covers 17 and 18 made of synthetic resin are fixed to the tips of the handle part 5 and the base 1. The recessed part 19 is formed in the resin cover 17 of the handle part 5.

In addition, the magazine part 3 is disposed inside the support wall 7 of the base 1, and the handle part 5 is disposed outside the support wall 7, and is provided on the common support shaft 2. It is rotatably supported by the. Both ends of the support shaft 2 are exposed to both side surfaces of the handle portion 5.

By the way, the said stapler is covered with the protective cover 14 made from synthetic resin on the upper surface of the base of the handle part 5. This protective cover 14 is softer than metal.

The protective cover 14 is formed in an inverted downward inverted cross-section from the upper surface portion 14a and both side portions 14b. The distance between both side portions 14b is formed to be substantially equal to the width of the handle portion 5. That is, the upper surface portion 14a of the protective cover 14 is formed to fit on the base of the handle portion 5, and the upper surface portion of the handle portion 5, and both side portions 14b are side surfaces of the handle portion 5. The upper end part of the upper surface part 14a is flat. 4A and 4B, projections 20 are formed on the rear surface of the upper surface portion 14a of the protective cover 14, and locking projections 21 are formed on the inner surface of both side portions 14b. . The protective cover 14 locks the locking projections 21 of the side portions 14b to the locking holes 22 formed on the side surface of the handle portion 5 with respect to the handle portion 5, and at the same time. It is provided by caulking 20 through the installation hole 23 formed in the upper surface of the handle part 5, and caulking.

Both side portions 14b of the protective cover 14 cover both ends of the support shaft 2 of the base 1.

1, the depression 24 is formed in the upper surface portion 14a of the protective cover 14. As shown in FIG. As shown in Fig. 5, the depression 24 is shaped to fit the thumb 30 when the stapler is reversed. In addition, the depression 24 is formed on the right side and the left side of the upper surface portion of the protective cover 14. However, as shown in FIG. 7, the depression 24 may be formed in the center of the protective cover 14. In addition, you may provide the non-slip part 24a in the said recessed part 24 or its vicinity. The anti-slip part may be a material that is uneven or slippery.

Next, as shown in Figs. 4A, 6A, and 6B, an accommodating groove 25 is formed on the top surface of the handle portion 5 on the rear surface side of the depression 24. The storing groove 25 is opened in the extending direction of the handle portion 5, and when the handle portion 5 is opened and developed to be straight with respect to the base 1, the base of the base 1 It is formed so that the remover 8 which protrudes from it can be accommodated.

Since the above-mentioned protective cover 14 is attached to the base of the handle portion 5 of the stapler, the following effects can be obtained.

(1) As shown in Fig. 5, in the case of using the stapler reversely, the protective cover 14 having the recessed portion 24 is attached to the upper surface portion 14a of the part which contacts the thumb 30, so that the metal Compared with this, it is less slippery, has a good feel, and is easy to carry, so that the holding property is good. Moreover, since the both side parts 14b of the protective cover 14 cover the edge part of the support shaft 2 of the base 1, since it does not hurt even if a force is applied at the time of iron work, operation feeling is good and workability is also good.

(2) A depression 24 is formed in the protective cover 14. Normally, the thumb 30 is in contact with the thumb 30 when the reverser is carried by the stapler, and this part is shaped into a shape that matches the thumb 30. Thus, since the recessed part 24 is formed in the part which becomes the support point at the time of the reverse holding operation by taking the thumb 30, iron operation can be performed stably.

(3) If the recessed part 24 is formed in the right side and the left side, it can respond to a right handed or a left handed. Of course, even if the recessed part 24 is formed in the center of the protective cover 14, it can respond to right-handed or left-handed.

(4) Since the protective cover 14 is formed in an inverted cross-section of the cross section, and the support shaft 2 of the base 1 is covered by both side portions 14b, not only is it safe as described above, Since the support shaft 2 is not exposed to the outside, the overall appearance is improved.

(5) The side portions of the handle portion 5, the side portions 14b of the protective cover 14, the upper surface portion of the handle portion 5 and the lower portion of the protective cover 14 are respectively engaged with each other. It is installed without the need for coupling parts such as pins.

(6) When the anti-slip portion is formed in the recessed portion 24, the thumb is hard to slip, and therefore the thumb is hardly released from the pit shape even when a force is applied when the stapler is used by reverse holding. And good operability.

(7) In the tucking operation of stapling the object, the handle 5 is opened and developed so as to be straight with respect to the base 1, but is projected from the base of the base 1 at the time of deployment. After the removed remover 8 has returned to the upper surface of the base of the handle part 5, it is stored in the storage groove 25 of the protective cover 14, so that a finger is removed between the handle part 5 and the remover 8. It can be secured at work without being caught or hit by injury.

(8) The circular part is formed in the part corresponding to the support shaft 2 of both side parts 14b. Since this circular part is associated with the rotation center, a natural appearance can be obtained.

(9) Since the said protective cover 14 is provided separately from the resin cover 17 of the front-end | tip part of a handle part, cost can be kept low by covering only a necessary part.

In addition, the shape of the part to which a thumb is put as long as it is effective to hang a finger is not necessarily made into a depression. It may be formed in a projection shape. For example, the upper surface portion 14a of Fig. 1 has a projection shape between the left and right depressions 24, and constitutes a projection shape, but at the time of inversion, the thumb is placed on the projection shape portion 14a. When holding, the thumb is hard to come off even if the work is applied with force when the stapler is reversely used, and thus workability and operability are good, and iron operation can be performed stably.

Similarly, Fig. 8 is formed in the center of the protective cover 14 of the base of the handle portion 5, and has a projection shape portion 26 having an elliptical periphery and a gently rising center. If the thumb is displaced, the thumb is hard to escape, and finger dialing is valid. When the constitution 26 is provided with elasticity, it does not hurt very much because it has elasticity even if it is strongly gripped when the stapler is reversed.

There is no particular limitation on the position and shape of the projection. As shown in FIG. 1, the protection cover 14 may be formed on the left and right sides, and the whole may be rectangular. Similarly, the shape of the recessed part 24 may be just about the degree to which a thumb does not move at the time of operation | work, and may be an elliptical shape like the recessed part 24 shown in FIG.

Moreover, you may provide the resin cover and protective cover of the front-end | tip part of a handle part integrally. For example, FIG. 10 is an example in which the resin cover 17 and the protective cover 4 are integrally provided through the connection cover 27, and the resin cover 17 and the protective cover 14 at the ends are each recessed ( 19 and 24 are formed. 11 is an example in which the resin cover 17 and the protective cover 14 are integrally provided through the connection cover 27, and the connection cover 27 covers the outer surface of the handle portion 5 and is at the front end. The recessed part 19 is formed in the resin cover 17, the protrusion part 26 is formed in the upper surface part of the protective cover 14, and the upper end is formed flat. In addition, a small projection 28 for preventing slipping is formed inside the depression 19.

As mentioned above, according to the structure which integrally provided the resin cover 17 and the said protective cover 14 of the front-end | tip part of a handle part, unity feeling or unity feeling can be expressed in the whole design.
