Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a pair of substantially parallel nail-shaped portions and a bridge portion provided between the nail-shaped portions so as to hold a linear object such as an electric wire on a wall surface. The present invention relates to a jig for a stapler for supporting a staple having a character-shaped main body at the time of driving.

[0002]

2. Description of the Related Art U-shaped staples have been conventionally used to hold electric wires on a wall surface. In such a staple, an electric wire or the like is sandwiched between parallel nail-shaped portions of a U-shaped main body, and the main body of the staple is hammered on a wall surface with a hammer or the like.

However, during the holding work by the above-mentioned staple, when the hammer is driven with a hammer, the main body of the staple is to be picked up and supported by a finger or the like. However, the shape of the staple itself is difficult to pick up, and it is difficult to support small. The work efficiency tended to decrease. Further, the driving depth when driving the staple is determined by the thickness of the electric wire or the like to be held, but it is difficult to control the force, and in some cases there is a risk of damaging the electric wire or the like. For example, Japanese Utility Model Laid-Open No. 3-15081 discloses a hammer with a tapping groove formed on the striking surface of the hammer, but when the hammer is held by the hammer itself, the staple, the electric wire, etc. Since it cannot be positioned in advance, the driving work becomes extremely difficult. Further, even with this structure, the problem that it is difficult to control the force when driving the staple is not solved, and in reality it is not very realistic.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the prior art described above, and its main purpose is to increase the efficiency of holding work of a linear object such as an electric wire by a staple. Moreover, it is to improve its reliability.

[0005]

According to the present invention, the above-mentioned object is provided between a pair of substantially parallel nail-shaped portions and between the nail-shaped portions so as to hold a linear object such as an electric wire on a wall surface. A jig for a stapler for supporting a U-shaped staple having a bridging portion at the time of driving, which is rod-shaped and has guide grooves each having a predetermined depth for guiding each of the nail-shaped portions. It has at one end a contact portion with the staple provided with a pair of parallel guide pieces, and at the other end a striking surface portion such as a hammer, at least between the guide pieces at the tip of the contact portion. This is achieved by providing a jig for a staple that is provided with an escape through which a linear object can be inserted. In particular, a pair of parallel guide pieces each having a guide groove of a depth different from the predetermined depth for guiding the nail-shaped portions on the other end side, and the relief are provided, and both ends are provided. It is preferable that the abutting portion also serves as the striking surface portion. Further, the above-mentioned object is to form the L-shaped staple with a pair of parallel guide pieces each having a guide groove of a predetermined depth for guiding each of the nail-shaped portions. It has a first abutting portion and a second abutting portion provided with a pair of parallel guide pieces each having a guide groove having a depth different from the predetermined depth at each end, and is provided with a hammer or the like. A staple jig having a striking surface portion at an intermediate bent portion, and at least a clearance through which the linear object can be inserted is provided between the guide pieces at the tip of each contact portion. It can also be achieved by doing.

[0006]

[Function] An electric wire or the like is sandwiched between both nail-shaped portions of the staple, and the jig is contacted with the staple in a guide groove having a predetermined depth. If you hit the jig with a mallet until the end face hits the wall, the staple will bite into the wall leaving only the depth of the guide groove. Further, by providing abutting portions for the staples on both ends of the jig, one jig can select two driving depths of the staple (biting). Further, by making the jig L-shaped, it is possible not only to directly hit the abutting portion with the staple but also to grip the portion parallel to the wall surface of the jig with a hand or the like to perform the work.
