CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based upon and claims the benefit of priority from prior Japanese patent application No. 2019-004220, filed on Jan. 15, 2019, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a striking tool configured to strike out a fastener from an ejecting port provided in a tip end of the tool, and particularly, to a striking tool for which it is possible to easily perform maintenance.

BACKGROUND ART

Such a type of the striking tool has a driver slidably arranged therein so as to strike the fastener. When replacing the driver, it is necessary to disassemble a body to expose the driver, so that it is troublesome to perform a failure repair. Also, since it is difficult for a user to disassemble the body and to again assemble the same, it is substantially impossible for the user to perform the replacement operation of the driver.

As related technology, for example, PTL 1 discloses a configuration in which a housing is configured by left side, right side and front side components. The front side component is detached to expose the driver, so that it is possible to replace the driver.

PTL 1: JP-A-2007-90473

However, in the configuration disclosed in PTL 1, it is necessary to largely open the front surface of the body so as to replace the driver. For this reason, the housing is configured by the left side, right side and front side components, which increases the cost due to complication of a mold structure and an increase in the number of components. Also, since an opening and closing structure is complicated, the tool is enlarged and the maintenance operability is not good.

Also, in the configuration disclosed in PTL 1, when replacing the driver, the driver stands by in a state in which a compression coil spring is compressed, so that the driver may operate during an operation. Therefore, a user cannot perform the replacement operation of the driver for a safety reason.

It is therefore an object of the present disclosure to provide a striking tool enabling a driver to be replaced safely and easily and having a simple structure.

SUMMARY OF INVENTION

According to an aspect of the present disclosure, there is provided a striking tool comprising: a driver which is provided to be slidable toward an ejecting port provided in a tip end of the striking tool so as to strike out a fastener from the ejecting port; a plunger to which the driver is coupled; a plunger urging member which is configured to urge the plunger toward the ejecting port; and a drive mechanism which is configured to move the plunger to accumulate urging force in the plunger urging member, wherein a standby position of the plunger before striking out the fastener can be switched between a usual standby position and a standby position for maintenance closer to the ejecting port than the usual standby position.
