By changing the traveling direction of the second nail body by parts, characterized in that to open leg tip.

  Further, the second configuration of the spread leg nail driving method according to the present invention has an inner diameter capable of fitting the head of the second nail body of the second configuration of the spread leg nail and the second configuration. A hole portion having a depth greater than or equal to a length in which the head of the nail body is disposed outside the head of the first nail body, and a contact portion with which the head of the first nail body abuts And a driving part having a driving part provided on the side opposite to the abutting part, and a method of driving the open leg nail of the second configuration using a driving tool, the hole of the driving tool The head of the second nail body is inserted into the part, the head of the first nail body is brought into contact with the contact part, and the driving part is driven in, so that the first nail body is advanced. After placing on the object, the driving jig is removed and the second head is driven, and the second nail is controlled by an open leg control unit provided at the tip of the first nail body. Characterized in that to open leg tip to change a traveling direction of.

  The first configuration of the member fixing bracket mounting method according to the present invention is a member fixing bracket mounting method having a through hole and a contact surface that contacts the surface of the object, The first and second nail bodies of the first structure of the open leg nail and the pipe are integrally inserted into the through hole of the bracket, and the first structure of the driving method of the open leg nail is driven. The head of the second nail body is inserted into the hole of the tool and the head of the first nail body is brought into contact with the contact portion to drive the driving portion into the first nail body. And the pipe are integrally driven in advance on the object, and the head of the first nail body is placed on the member in a state where the contact surface of the member fixing bracket is in contact with the object. After locking to the periphery of the through hole of the fixing bracket, the driving jig is removed and the second head is driven Then, an opening leg control unit provided at the tip of the first nail body changes the advancing direction of the second nail body to open the tip, and the head of the second nail body is moved toward the head. The member fixing bracket is fixed to the object by engaging with a peripheral edge portion of the through hole of the member fixing bracket.

  Further, a second configuration of the member fixing bracket mounting method according to the present invention is a member fixing bracket mounting method having a through hole and a contact surface that contacts the surface of the object. The first and second nail bodies of the second configuration of the open leg nail are integrally inserted into the through hole of the bracket, and the driving jig of the second configuration of the method of driving the open leg nail is The head of the second nail body is inserted into the hole, the head of the first nail body is brought into contact with the contact portion, and the driving portion is driven to lead the first nail body ahead. The head of the first nail body is engaged with the peripheral edge of the through hole of the member fixing bracket in a state where the member fixing bracket is in contact with the target object. After stopping, the driving jig is removed and the second head is driven, and is provided at the tip of the first nail body. The opening control unit changes the advancing direction of the second nail body to open the tip, and the head of the second nail body is locked to the peripheral edge of the through hole of the member fixing bracket. The member fixing bracket is fixed to the object.

  Further, the mounting structure of the member fixing bracket according to the present invention is a mounting structure of a member fixing bracket having a through hole and a contact surface that comes into contact with the surface of the object, and is provided in the through hole of the member fixing bracket. The first and second nail bodies and the pipe of the first configuration of the open leg nail are integrally inserted, and the first and second nail bodies and the pipe are attached to the object. And the tip of the second nail body is opened by changing the advancing direction by an opening control unit provided at the tip of the first nail body. The abutting surface of the bracket abuts on the object, and the heads of the first and second nail bodies are locked to the peripheral edge of the through hole of the member fixing bracket so that the member fixing bracket is the object. It is characterized by being fixed to.

  According to the first configuration of the open leg nail according to the present invention, the first and second nail bodies configured separately are inserted into the pipe in parallel and restrained so as to be slidable in the axial direction of each other. The Then, after driving the head of the first nail body and placing the first nail body and the pipe in advance on the object, the head of the second nail body is driven and the second nail is driven. The body can be subsequently placed on the object. Then, after the first nail body is reliably placed on the object, the advancing leg control unit provided at the tip of the first nail body changes the traveling direction of the subsequent second nail body. Thus, the tip of the second nail body can be opened in the object. The pipe can reliably restrain the traveling direction of the second nail body driven along the first nail body, and can surely open the tip of the second nail body.

  Moreover, according to the 2nd structure of the spread leg nail which concerns on this invention, the 1st, 2nd nail body comprised by the separate body is inserted in parallel in the hole of at least 1 washer, Restrained to be slidable in the axial direction. Then, after driving the head of the first nail body and placing the first nail body on the object in advance, the head of the second nail body is driven and the second nail body is followed. And can be placed on the object. Then, after the first nail body is reliably placed on the object, the advancing leg control unit provided at the tip of the first nail body changes the traveling direction of the subsequent second nail body.
