Problems solved by technology

Therefore, even in the case of using a contact head structure, it is necessary to form the inner diameter of the contact head to match the maximum diameter of the fastener that can be used. Cannot completely suppress the tilting of the fasteners in the contact head
Therefore, there is the potential for fasteners to fire obliquely, buckling fasteners
[0006] In particular, in a driving tool having a fastener supply mechanism that supplies the connected fasteners one by one into the injection path of the machine head, the fasteners are driven in a state where the guidance of the fasteners is insufficient. The posture of the driven fastener is not fixed
Therefore, even when the contact nose structure is used, the inclination of the fastener cannot be completely suppressed

Embodiment Construction

[0090] Embodiments of the present invention will be described with reference to the drawings.

[0091] The fastener driving tool 10 of the present embodiment is an air pressure driving tool that utilizes compressed air to drive the fastener 41, such as figure 1 As shown, there are: a tool main body 11 having a nose portion 13 and a nail magazine 19 connected to the tool body 11 on the side of the nose portion 13 .

[0092] In the tool main body 11, the main body case 12 and the mobile phone case 16 are connected at substantially right angles and constituted. A striking cylinder is disposed inside the main body casing 12 , and a striking piston is slidably accommodated in the striking cylinder. The driver 21 for striking the fastener 41 is arranged in combination with the lower surface of the striking piston, and the fastener 41 can be driven in by the driver 21 when the striking piston moves.

[0093] A handpiece 13 for injecting fasteners 41 is provided at the lower front e...

Abstract

A fastener driving tool injects a fastener from an injection passage formed in a leading end of a tool main body. The injection passage includes therein a guide portion formed along a driving direction of the fastener for guiding the fastener. The guide portion is formed by providing contours having mutually different distances from a center of the injection passage in a cross-section of the injection passage.

Description

technical field [0001] The invention relates to a fastener driving tool. Background technique [0002] In conventional fastener driving tools, when using fasteners with small head diameters, small wire diameters, and short lengths, the angle of inclination of the fasteners during driving in the injection path becomes large, causing buckling. tend to increase in frequency. [0003] In order to suppress occurrence of such defective driving (buckling), conventionally, a touch head has been used (for example, refer to Patent Document 1). The contact head is a part connected to the front end of the contact arm that constitutes the safety device of the fastener driving tool. By pressing the contact head against the surface of the driven part, the contact arm moves upward to form a driving force. Hit the state of the institution. By forming the inner diameter of the contact nose substantially equal to the inner diameter of the nose, it is possible to suppress the inclination of ...
