Throwing-into tool

Abstract

PROBLEM TO BE SOLVED: To provide a nailing machine in which an opening / closing cover is held in a surely closed state in the whole area even if receiving a shock such as a nailing shock while providing convenience for nailing when a nail is driven in corners since such a problem has occurred hitherto that the opening / closing cover is liable to float on the side of an injection port when a locking mechanism which is projected into the lateral side from a driving guide including the opening / closing cover for preventing the clogging of nails is moved backward as far as possible to provide convenience for nailing when the nail is driven in corners. SOLUTION: A front-side closing part 20 is arranged at the front side of the locking mechanism 12 arranged at the back side of the driving direction separately from the locking mechanism 12 so that a passage-side engaging part 18 of the front-side closing part 20 is engaged with and disengaged from a cover-side engaging part 11d by the opening / closing operation of the locking mechanism.

Description

technical field [0001] The present invention relates to driving tools such as concrete pneumatic nailers, floor tackers and the like. Background technique [0002] Since this driving tool is provided with a tool body part in which a driving mechanism is housed, and a driver guide part extending from the front end of the tool body part, a driving part supplied in the driving passage in the driver guide part It is struck by the driver and ejected from the front end (injection port) of the driver guide. [0003] For example, an opening and closing cover is provided on the driver guide portion, and the driving passage can be opened through the opening and closing cover to remove a clogged driving tool. In many cases, in order to open and close within a certain range along the insertion direction of the driver guide, the upper side of the access cover is supported by the driver guide so as to be rotatable up and down. [0004] In the driver guide part, the driver that moves dow...

AI Technical Summary

Problems solved by technology

[0008] However, if the driving tool is configured such that the locking mechanism is arranged on the rear side of the opening and closing cover in the driving direction, and the elastic force of the spring is applied to the center in the front and rear direction avoiding the front side (near the injection port) , Pushing in the closing direction, the closing force (pressing force in the closing direction) of the front side of the opening and closing cover (the front end side in the driving direction) becomes smaller, and it is easy to produce a lift in the opening direction. The problem that the guiding function of the driving tool is reduced due to the contact of parts, etc.
