AI Technical Summary

Technical Problem

Conventional dry driving prevention mechanisms in driving tools suffer from inaccuracies in detecting the remaining amount of driving tools due to dimensional errors and rattling between the pusher and detection section, leading to potential shakiness and blank firing issues.

Method used

The driving tool incorporates a support member that rotatably connects to the pusher, with a detection member sensing the support member's position to accurately detect the remaining amount of driving tools, using a protrusion and a microswitch for precise detection, and a lever member to amplify the movement for reliable detection.

Benefits of technology

This design enhances the accuracy of detecting the remaining driving tools, reducing errors and preventing blank firing by ensuring precise detection of the support member's position, thus maintaining operational efficiency.

Abstract

To provide a driving tool that enables a remain amount of the driving tool to be more highly accurately detectable unlike conventional ones having difficulty in accurate detection of the remaining amount of the driving tool due to accumulation of dimensional errors or backlash that may occur between a pusher and a detection unit in a conventional blank-firing preventive mechanism.SOLUTION: A driving tool is configured to detect, by a detection member 45, a position of a support member 36 that connects a pusher 35 to a pusher base 33 in a rotatable manner. Thereby, the position of the pusher 35 is detected by a portion that has a smaller accumulated error and backlash than conventional ones so as to prevent blank-firing more highly accurately.SELECTED DRAWING: Figure 4
