BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nailing machine having a nose portion which forms a nail driving hole for continuously driving nails by using power of compressed air or the like.

[0002]

2. Description of the Related Art In a conventional nailing machine, for example, a magazine containing a large number of nails is formed to form a nail driving opening for slidably guiding a striking driver connected to a piston driven by compressed air pressure. A nail driving hole is formed between a wear plate formed at the front end of the vehicle and a plate-shaped driver guide which is further arranged on the front surface of the wear plate. Usually, in order to fix the wear plate and the driver guide to the nailing machine body, the wear plate and the driver guide are fastened and fixed by a hexagon socket head bolt or the like mounted from the front of the driver guide. But by screwing

In the case of a nailing machine used for finishing furniture or the interior of a house, for example, a screw head or driver guide whose nailing position is close to the corner is exposed on the outer surface of the nose. It often happens that it is injured by contacting the peripheral edge of the head. Conventionally, there is no appropriate means for protecting such a material to be driven, and an operator is required to work with a nerve so as not to damage the material to be driven, which causes a reduction in work efficiency. ing.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems in the conventional nailing machine and to provide a nailing machine which does not damage the material to be driven. is there.

[0005]

SUMMARY OF THE INVENTION A plastic cover covering almost the entire front and side surfaces of the nose is mounted on a nose which guides the impact driver of the nailing machine so as to be able to be impulsively driven. The outer surface is configured to be higher than the protrusion height of the fixed component.

[0006]

Since almost the entire front and side surfaces of the nose portion are covered with a plastic cover, the side edges of the metal driver guide can be prevented from directly contacting the material to be driven. Is formed so that the outer surface thereof is higher than the protruding height of fixed parts such as hexagon socket head bolts, so that these fixed parts can be prevented from contacting the material to be driven.

[0007]

[Effect of the Invention] The cover prevents the fixed parts such as the driver guide and bolts from coming into contact with the material to be driven.
The surface of the material to be driven is not damaged by the contact between the metal component and the material to be driven, and the nailing operation can be performed by the operator without using a nerve, so that the working efficiency can be improved. In addition, since the outer surface of the cover body only needs to be formed higher than the protruding height of the fixed component, the cover body can be mounted in close contact with the driver guide. It does not impair the workability of the driving.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 shows a nailing machine equipped with a cover body according to the present invention. A magazine 3 having a wear plate 3 attached to a front end thereof is fixed to a lower portion of a body 1 of the nailing machine by a hexagon socket head bolt 7. A guide groove 3 'for guiding a nail driving driver D driven by an impact mechanism (not shown) is formed on the front surface of the plate 3.

A driver guide 4 is fixed to the wear plate 3 by set screws 6 and 6 so as to face the front surface of the wear plate 3. Between the driver guide 4 and the wear plate 3, a contact arm 5, which constitutes a wall in front of the guide groove for guiding the driver D, is disposed so as to be sandwiched between the two members. The contact arm 5 is slidable along the nail driving direction between a position where the tip projects forward in the nail driving direction and a retracted position, and also serves as a part of the safety mechanism.

Further, a cover body 8 made of a plastic material is attached so as to cover most of the front surface and a part of the side surface of the nose portion composed of the wear plate 3, the contact arm 5 and the driver guide 4. ing. As shown in detail in FIGS. 5 to 7, the cover body 8 has a front wall 9 formed so as to cover almost the entire area of the driver guide 4.
And a side wall 10 extending rearward from both side edges of the front wall 9
The front wall 9 has an opening 11 for accommodating the head of a set screw 6 for attaching the driver guide 4 to the wear plate 3, and a hexagonal hole for fixing the wear plate 3 to the nailer body 1. A recess 12 for accommodating the head of the bolt 7 is formed. The outer surface of the front wall 9 is formed so that the heads of the set screw 6 and the hexagon socket head cap screw are higher than the height of the screw which protrudes from the driver guide surface when the cover body 8 is mounted. The head of the bolt 7 does not project outside the outer surface of the cover body 8.

A locking projection 13 is integrally formed on the side wall 10 of the cover body 8 inward from the inner surface of the side wall. The cover body 8 is held by holding the driver guide 4 therebetween.
The cover body 8 is attached to the wear plate 3 by a set screw 6 inserted through an opening 11 formed in the cover body 8 in this assembled state. Mounted on the nose.
