Problems solved by technology

[0002] In the European and American nail gun market, nail guns are not only professional tools, but also suitable for simple decoration and decoration of ordinary families and individuals. For U nails with different length nail feet (6-14mm), the nail gun includes a nail feeding guide rail, a punching guide rail and a punching sheet. A nail output gap is formed between the punching sheet guide rail and the end of the nail feeding guide rail. Move downwards in the nail output gap to punch out the U nails. Since the U nails with different lengths of nail feet are fed by the same nail feeding guide rail, and the nail feeding guide rail adopts flat clamping and positioning, the distance between the nail feet of short U nails is out of reach. The nail mouth is far away. Before reaching the nail outlet, the punch will push it for an uncontrolled stroke. During this uncontrolled stroke, the nail will fall over, tilt, etc., causing it to hit the wooden board. The nails have defects such as overturning, tilting, and failure to drive to the bottom, and the nailing quality is unstable

Embodiment 1

[0038]refer to Figure 1 to Figure 6 As shown, the nail gun in this embodiment includes a housing and a drive mechanism, and the housing is also provided with a nail feeding guide rail 100, a punching guide rail 200, a punching plate 300 and an adjustment member 400, and the punching guide rail 200 and the nail feeding guide rail 100 A nail-out gap 600 for accommodating U nails 500 is formed between the ends, and the drive mechanism is an electric drive mechanism or a pneumatic drive mechanism. These two drive mechanisms have been disclosed in the prior art and will not be described in detail here. The mechanism drives the punching piece 300 to move downward in the nail-out gap 600 to punch out the U nail 500. When nailing, the adjustment member 400 and the punching piece 300 cooperate to adjust the U nail 500 to abut against it in the nail-out gap 600. On the punching guide rail 200, so that the U nail 500 sticks to the punching guide rail 200 for nailing, avoids the U nail 5...

Embodiment 2

[0044] The difference from Embodiment 1 is that the adjustment member in this embodiment includes a fixed arm and a support piece 420 located at the lower end of the fixed arm, the upper end of the fixed arm is hinged on the mounting surface 220, and a There is a return spring, and the support piece 420 runs through the perforation 230. The part of the support piece 420 located in the nail output gap 600 forms an elastic protrusion 700. The support piece 420 is a slanted piece that slopes downward toward the nail feeding guide rail 100, so that the elastic protrusion The top surface of 700 forms a bevel. In this embodiment, under the cooperation of the fixed arm and the return spring, the support piece 420 can be retracted into the perforation 230 or extended into the nail-exiting gap 600, so that the part of the support piece 420 located in the nail-exiting gap can be displaced and formed. Elastic bump 700.

[0045] When nailing, the nail back of the U nail is supported by t...

Embodiment 3

[0048] Compared with Embodiments 1 and 2, the difference of this embodiment is that the elastic projection 700 in this embodiment protrudes into the nail-exiting gap 600 and protrudes from the guide surface 210 at a height smaller than the width of the nail back, so that First, when nailing, one side of the back of the nail can also be hung on the elastic protrusion 700, and the other side can be twisted downward under the impact of its own weight and the punching plate 300 so that the bottom end of the nail foot abuts against the punching plate guide rail 200, and under the impact of the subsequent punch 300, the elastic protrusion 700 retracts into the perforation 230 so that the back of the nail is twisted to lean against the punch guide rail 200. At this time, the top surface of the elastic protrusion does not need to be provided with a slope .

Abstract

The invention discloses a nail gun. The nail gun solves the technical problem that in the prior art, the nailing quality of a nail gun is unstable. The nail gun comprises a shell and a driving mechanism. A nail feeding guide rail, a rushing sheet guide rail, a rushing sheet and an alignment piece are further arranged in the shell. A nail outlet gap which is used for holding a U nail is formed between the ends of the rushing sheet guide rail and the nail feeding guide rail, and the driving mechanism drives the rushing sheet to move downwards in the nail outlet gap so as to rush out the U nail. When nailing is conducted, the alignment piece is matched with the rushing sheet to align the U nail in the nail outlet gap to be attached to the rushing sheet guide rail, and therefore the U nail can be discharged in the mode of being attached to the rushing sheet guide rail.

Description

【Technical field】 [0001] The invention relates to the technical field of nail guns, in particular to a nail gun. 【Background technique】 [0002] In the European and American nail gun market, nail guns are not only professional tools, but also suitable for simple decoration and decoration of ordinary families and individuals. U nails with different lengths (6-14mm) are used in the process of use. , the nail gun includes a nail feeding guide rail, a punching guide rail and a punching sheet. A nail output gap is formed between the punching sheet guide rail and the end of the nail feeding guide rail. The punching sheet moves downward in the nail output gap to punch out the U nails. Due to different U nails with long feet are all fed by the same nail feeding guide rail, and the nail feeding guide rail is clamped and positioned on a plane, so the nail legs of short U nails are far away from the nail outlet, and the punching sheet will be cut before reaching the nail outlet. Push ...
