Disclosed herein is a nailer having an improved safety device. With the improved safety device, a movable plate, which is adapted to slidably move along a lower surface of a guiding unit, is formed, at a certain location thereof, with an insertion hole for the insertion of a protrusion formed at a trigger. Thereby, if the trigger is pulled in a pressed state of the movable plate, a nailing operation is accomplished. Also, in the course of pulling the trigger, the movable plate can be further inserted rearward by a predetermined distance under interaction of the insertion hole and protrusion. This has the effect of eliminating the risk of causing scratches on a nailing surface of a target structure even if the movable plate is moved while coming into close contact, at a front end thereof, with the nailing surface, resulting in several advantages, such as for example, easy nailing operation, operator's convenient working posture, and rapid and safe nailing operation.

What is claimed is: 1. A nailer including a body, a magazine, a guiding unit, a latch, a handle, a plunger, a body cover, and a trigger, the nailer comprising: a safety device being inserted through the trigger for sliding along a lower surface of the guiding unit, a rear end of said safety device

What is claimed is: 1. A nailer including a body, a magazine, a guiding unit, a latch, a handle, a plunger, a body cover, and a trigger, the nailer comprising: a safety device being inserted through the trigger for sliding along a lower surface of the guiding unit, a rear end of said safety device attached perpendicular to the trigger for controlling operation of the trigger, said trigger having a trigger body configured to be pressed by the operator's finger, an insertion hole perforated in a front portion of said trigger body at a position close to an upper end of the front portion to allow a retardant portion of a movable plate to be inserted therethrough, a control protrusion formed at an inner periphery of said insertion hole at an upper end position of an inner periphery thereof, said control protrusion being inserted into the insertion hole perforated in the movable plate, shaft holes perforated through opposite side portions of the trigger body at upper end positions of side portions thereof, and an inner trigger member attached to a rear end portion of the trigger for pressing the plunger when the trigger is pressed. 2. The nailer according to claim 1, wherein the safety device further comprises a multiply-bent movable plate for sliding along the lower surface of the guiding unit, a contact portion formed at a front end of the movable plate for contacting with a target structure, an elongated hole perforated in a central location of the movable plate so that a screw is fastened therethrough to limit a moving distance of the movable plate, said retardant portion formed at a rear end of the movable plate to extend perpendicular to the ground, and said insertion hole perforated in a central location of the retardant portion. 3. The nailer according to claim 1, wherein the control protrusion is configured to protrude forward from the trigger body by a predetermined angle, when the trigger is fully pulled after the control protrusion of the trigger is inserted into the insertion hole perforated in the movable plate, the control protrusion causes the movable plate to be further pulled toward the handle by a predetermined distance, thereby preventing the contact portion of the safety device from causing scratches on a nailing surface even if the nailer is moved in a state wherein a front end of the guiding unit included in the nailer comes into close contact with the nailing surface. 4. The nailer according to claim 3, wherein the insertion hole has formed a rounded inner surface to allow the control protrusion to be inserted along the rounded surface. 5. The nailer according to claim 3, wherein an insertion recess is formed in the retardant portion of the movable plate, to allow the control protrusion to be inserted thereinto.
