Embodiment Construction

[0025] Then based on Figure 1 to Figure 4 Embodiments of the present invention will be described. figure 1 The entire driving tool 1 according to the present embodiment is shown. The driving tool 1 of the present embodiment has a characteristic about the guide member 10 for guiding the driving tool n in the vicinity of the injection port, and other basic structures as the driving tool are not particularly changed, so detailed description is omitted. In addition, in this specification, regarding the up-down direction of components or structures, the driving direction of the driving tool n is set ( figure 1 The lower side in ) is the lower side, and the opposite direction thereof is the upper side.

[0026] The driving tool 1 is a compressed air-driven nailer, and includes: a main body part 2 in which a piston 7 is housed; a handle part 3 extending laterally from the side part of the main body part 2; The cylindrical driver guide part 4 is provided in a state where the lower...

Abstract

The invention provides an impact tool. In the nailing machine and the like impact tool, a directing component that is slope or limits the position of the impact tool is configured at the vicinity of the exit, so that even if the nail with fine head can beat out straightly from the central of the exit, and the directing component is specifically required to further improve the impact resistance of the support part. The invention is object to improve the impact resistance of the directing component. The directing component 10 is rotably supported on the surroundings of the rotary fulcrum 11 of the drive piece directing part 4 to clip the buffering components (12, 12), and the buffering components (12, 12) are used to absorb the impact of nail n during impact.

Description

technical field [0001] The present invention relates to a driving tool such as a compressed air-driven nailer that is used by a user by hand. Background technique [0002] For example, a compressed air-driven driving tool includes: a main body part in which a piston reciprocated by compressed air is housed; A driver passage through which a driver for striking the driver is inserted; a handle portion extending laterally from a side portion of the main body portion; entry. [0003] When a switch lever in the form of a trigger provided near the base of the handle portion is operated by fingertips, compressed air is supplied to the upper cylinder chamber of the main body portion to move the piston downward. When the piston moves downward by the thrust of the compressed air, the driving member moves downward in the driving passage, and in the middle of its downward movement, a driving member n is struck and ejected from the injection port. [0004] In such a driving tool, the ...
