[Structure of Fixing Tool Driving Machine 1]
As shown in FIG. 1, the fixing tool driving machine 1 has mainly a driving tool 10, a first fixing portion 20, a pulley 25, a second fixing portion 30, a rod-shaped member 40, a first operating portion 50, and a connection. A unit 60, an action unit 70, a second operation unit 80, and a leg unit 90 are provided.

The driving tool 10 is a tool for driving a fixing tool 15 such as nails, staples, and screws into an object to be constructed such as a building material. For example, the driving tool 10 holds the fastener 15 inside. Then, when the trigger 11 is pulled (an example of a predetermined operation) while the tip portion 12 of the driving tool 10 is pressed against the object to be constructed (that is, in contact with the object to be constructed), the fixing tool 15 is driven by the air pressure from the air compressor. Is punched out from the tip portion 12, and the fixing tool 15 is driven into the work piece.
The tip portion 12 functions as a safety device, and in a state where the tip portion 12 is not pressed against the object to be constructed, even if the trigger 11 is pulled, the driving tool 10 does not drive the fixing tool 15.

Here, the driving tool 10 is fixed to the first fixing portion 20. The driving tool 10 and the first fixing portion 20 are fixed by, for example, fasteners such as screws and bolts.

The first fixing portion 20 is slidably attached to the second fixing portion 30. Specifically, as shown in FIG. 5, a convex sliding portion 22 is formed in a portion of the first fixing portion 20 facing the second fixing portion 30.
