Therefore, since the pair of mounting portions 41 at the base portion of the extruded body 7 holds the single extruded gear 12 even though the number of gears is reduced, it can be stably operated.

(Operation of the embodiment)
The fastening member pushing tool of this application is the said structure, and shows an example of an assembly below.
The front end side is one of the one side case 35 and the other side case 36 of the main body case 1 that is a cylindrical member in which the opening 5 is opened. For example, the one side case 35 is provided with one side surface 10. One side gear groove 11 is provided on one side surface 10 of one side case 35.
The base portion of the extruded body 7 having the head pushing portion 14 whose tip protrudes from the opening portion 5 of the one side case 35 is mounted on the mounting shaft 13 of the pushing gear 12. The extruded body 7 and the extruded gear 12 are accommodated in the one-side case 35 so that the extruded gear 12 meshes with the one-side gear groove 11.

The support body 20 having the other-side gear groove 21 formed on the surface facing the one-side gear groove 11 of the one-side case 35 is fitted into the one-side case 35 so that the other-side gear groove 21 meshes with the push gear 12. .
In addition, any order may be sufficient as the mounting order to the one side case 35 of the extrusion gear 12, the extrusion body 7, and the support body 20. FIG.
A guide gear 32 is fitted and meshed between the guide groove 31 on the outer periphery of the extruded body 7 and each of the one side gear groove 11 and the other side gear groove 21.
In this state, when the one side case 35 is fixed so as to be covered by the other side case 36, the assembly is completed.

The fastening member pushing tool abuts the abutting portion 22 of the support body 20 on the surface of the surface portion 3, and positions the fastening member 2 between the head pushing portion 14 and the surface portion 3 of the extruded body 7, When the main body case 1 is pushed toward the surface portion 3 by the handle 4, the main body case 1 approaches the surface portion 3 while the one side gear groove 11 rotates the push gear 12.
When the main body case 1 is brought close to the surface portion 3, the extrusion gear 12 meshed with the other side gear groove 21 of the support 20 moves toward the opening 5 while rotating clockwise in FIG. Thus, the extruded body 7 moves toward the surface portion 3, and the extruded body 7 pushes the fastening member 2 toward the surface portion 3 and pushes it into the surface portion 3.

Therefore, the extrudate 7 amplifies the human force that becomes a driving source for pushing the main body case 1 by the diameter of the push gear 12 of the boost push mechanism 6 and pushes the fastening member 2 toward the surface portion 3. Make pushing work easier.
The fastening member pushing tool pushes the extruded body 7 out of the main body case 1 by the booster pushing mechanism 6 constituted by the one side gear groove 11, the pushing gear 12 and the other side gear groove 21 of the support 20. No hitting sound is generated when the landing member 2 is pushed.
That is, the head extruding portion 14 of the extruded body 7 is pushed toward the surface portion 3 without leaving the head of the fastening member 2, so that an impact sound due to striking like a hammer is not generated.

The support body 20 is provided with a set mechanism 23 that protrudes the contact portion 22 from the main body case 1 toward the surface portion 3 to a predetermined position, and the set mechanism 23 urges the support body 20 to protrude toward the surface portion 3. And the stopper 26 for stopping the movement of the support 20 by the spring 24 at a predetermined position, the support 20 is biased by the spring 24 in the direction of the opening 5 before starting work. The contact portion 22 is stopped at a predetermined position by the stopper 26 and protruded from the main body case 1.
Therefore, the abutting portion 22 at the tip of the support body 20 is spaced at a predetermined interval so that the fastening member 2 is inserted between the head pushing portion 14 and the surface portion 3 at the tip of the extruded body 7. The head extruding part 14 is positioned.

In this state, the abutting portion 22 of the support 20 is brought into contact with the surface of the surface portion 3, the fastening member 2 is positioned between the head extruding portion 14 and the surface portion 3 at the tip of the extruded body 7, and held. When the body case 1 is pushed toward the surface portion 3 against the elasticity of the spring 24 by the hand 4, the pusher 12 pushes the fastening member 2 by the movement of the push gear 12 and pushes it into the surface portion 3.
Next, when the contact portion 22 of the support body 20 is removed from the surface of the surface portion 3, the contact portion 22 of the support body 20 protrudes from the opening portion 5 of the main body case 1 by the elasticity of the spring 24, and the next fastening is performed. The pushing operation of the member 2 is performed.
The stopper 26 of the set mechanism 23 is provided on the support 20 and is formed so as to be freely disengaged from the fixed side engaging member 27 provided on the other side surface 25 of the main body case 1. The stopper 26 provided on the support 20 is brought into contact with the member 27, and the contact portion 22 at the tip of the support 20 is positioned at a predetermined position with respect to the main body case 1.

On the contrary, when the main body case 1 is pushed toward the surface portion 3 by the handle 4, the stopper 26 moves from the fixed side engaging member 27 to the inner side of the main body case 1, and the spring 24 is extended. When the contact portion 22 of the support 20 is removed from the surface, the spring 24 contracts and returns the contact portion 22 of the support 20 to the work start position.
Since the pressing operation of the fastening member 2 performed by pressing the main body case 1 against the surface portion 3 can be performed as a continuous repetitive operation simply by removing the contact portion 22 of the support 20 from the surface of the surface portion 3, workability is improved. It is done.
Since a guide mechanism 30 for guiding the push-out movement of the pusher 7 is provided at a predetermined position on the opening 5 side of the pusher gear 12 in the main body case 1, the pusher 7 passes through the main body case 1 in the opening 5.

Since the guide gears 32 are engaged with each other between the guide grooves 31, when the extruded body 7 moves, the guide gears 31 are engaged with the guide grooves 31 facing the one side gear groove 11 and the other side gear groove 21. The guide gear 32 rotates, and the extruded body 7 moves while being sandwiched between the guide gears 32 on one side and the other side.
Therefore, the extrudate 7 moves smoothly and reliably in the main body case 1 toward the opening 5, thereby improving workability.
Similarly, since the roller 33 is provided between the support body 20 and the other side surface 25 of the main body case 1, the movement of the main body case 1 with respect to the support body 20 can be made smooth and workability can be improved.

In another embodiment of FIG. 5, a small-diameter gear 40 having a smaller diameter than the push-out gear 12 is integrally provided on the push-out gear 12 meshed with the one-side gear groove 11 in the main body case 1. 7, when the main body case 1 is brought close to the surface portion 3, the extrusion gear 12 meshed with the other-side gear groove 21 of the support 20 is rotated in FIG. 5, the extruded body 7 moves toward the surface portion 3 by the moving rotation of the small-diameter gear 40 that rotates integrally with the extrusion gear 12, and the extruded body 7 pushes the fastening member 2 toward the surface portion 3 to face the surface portion. Will be pushed into 3.
Therefore, the fastening member 2 is pushed out toward the surface portion 3 by further amplifying the manpower as a driving source by the gear ratio with the diameter of the pushing gear 12 of the booster pushing mechanism 6 and the small-diameter gear 40, and the fastening member 2.
