Description

nail gun

The invention relates to a nail gun.

In many fields, there is often a need to arrange cables according to different environments or work requirements, and the cables may be electrical cables or non-electric cables. Among them, the demand for arranging conductive cables by building circuits is more common.

Wherein, the cable is usually fixed on a setting base (such as wood or similar base). Since the cable is extremely long and flexible, it is difficult to make it straight and positioned. Therefore, a nail gun is usually used, such as a ㄇ-shaped nail to fix it. However, if the position of the cable is not stably maintained before fixing the cable with the nail, the cable is easily misaligned, which is not conducive to the fixing operation, and the nail may also damage the cable.

US5497931 discloses a crimping structure suitable for multi-size cables, which selects crimping grooves of different sizes through an adjustment piece arranged on the nail gun body through swinging, so as to be suitable for fixing cables of different sizes. However, the swinging adjustment piece requires a large space for its swinging, resulting in a large size of the nail gun, and the swinging structure is also relatively unstable and easily damaged.

Therefore, it is necessary to provide a novel and progressive nail gun to solve the above-mentioned problems.

The main purpose of the present invention is to provide a nail gun, which can stably hold a cable, and is beneficial for nailing the cable.

To achieve the above object, the present invention provides a nail gun, comprising: a nail gun body, including a front end, the front end includes a nail outlet and an end plate, the end plate includes a groove adjacent to the nail outlet; A holder, switchably arranged on the nail gun body, including a plurality of notches with different sizes and a plurality of first positioning parts; and a positioning member, arranged on the nail gun body, and one of the first positioning parts The parts are releasably positioned relative to each other such that one of the notches corresponds front and rear to the groove for receiving a portion of a cable.

The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention.

Please refer to FIGS. 1 to 11 , which show a preferred embodiment of the present invention. The nail gun 1 of the present invention includes a nail gun body 10 , a holder 20 and a positioning member 30 .

The nail gun body 10 includes a front end 11, the front end 11 includes a nail outlet 12 and an end plate 13, the end plate 13 includes a groove 14 adjacent to the nail outlet 12; the holder 20 can be switched Located on the nail gun body 10, the retainer 20 includes a plurality of notches 21 of different sizes and a plurality of first positioning portions 22; the positioning member 30 is arranged on the nail gun body 10, and the positioning member 30 and one of The first positioning portions 22 are releasably positioned with each other such that one of the notches 21 corresponds to the groove 14 front and back and can receive a part of a cable. Thereby, after switching the holding member 20 to select an appropriate one of the notches 21, the positioning of the holding member 20 can be maintained and the cable can be stabilized, which is beneficial to fixing the cable with the needle.

The nail gun body 10 further includes a striker 15 for firing the nail 100, the retainer 20 is disposed on the front end 11, the end plate 13 includes a guide groove 131, and the striker 15 is slidably disposed in the guide groove 131 During this process, the nail needle 100 can be stably impacted. In this embodiment, the holder 20 is rotatably disposed on the front end portion 11 , and each notch 21 and a first positioning portion 22 are disposed opposite to each other in a radial direction of the holder 20 .

In detail, each of the notches 21 includes two opposite straight sides 211, two shoulders 212 and a concave arc portion 213, the two shoulders 212 are respectively transversely connected to the two straight side portions 211, and the concave arc portions 213 are respectively Connected to one end of each of the shoulders 212 , the notch 21 is divided into a rectangular section 214 and an arcuate section 215 by a line connecting the two shoulders 212 ( FIG. 4 ). Wherein, the rectangular section 214 is suitable for a rectangular or wide flat cable 200 ( FIG. 10 ), and the arcuate section 215 is suitable for a round cable 300 ( FIG. 11 ), which has wide applicability.

The positioning member 30 includes at least one second positioning portion 31, one of the first positioning portion 22 and the second positioning portion 31 includes a card recess, and the other includes a card that is releasably positioned with the card recess. convex. In this embodiment, the first positioning portion 22 includes the locking recess, and the second positioning portion 31 includes the locking protrusion. The structure of the card concave and the card convex is simple and the positioning is stable.

The holder 20 further includes a plurality of size indicating portions 23 , each of which is radially corresponding to one of the notches 21 for clearly indicating the selected size of the notch 21 . The locating member 30 further includes a locating slot 32 , each of the size indicating portions 23 is releasably engaged in the locating slot 32 . Rotate the holding member 20 so that a size indicating portion 23 is locked in the positioning groove 32 , and one of the notches 21 of a desired size can be quickly selected.

The positioning member 30 is movably arranged on the front end portion 11. Specifically, the end plate 13 further includes a slide groove 132, and the positioning member 30 further includes a guide protrusion 33, a base block 34 and a set of columns 35. The guide protrusion 33 and the sleeve post 35 extend from the base block 34 and are transverse to each other. The guide protrusion 33 is slidably disposed in the slide groove 132 , and the movement is smooth, stable and precise.

The nail gun 1 further includes an elastic member 40 , the elastic member 40 bounces between the front end portion 11 and the positioning member 30 . Specifically, the elastic member 40 is a coil spring and is sleeved on the sleeve 35, and the at least one second positioning portion 31, the sleeve 35 and the coil spring are arranged in a straight line, so that the elastic member 40 can be stably And the positioning member 30 is effectively pushed and pushed to provide excellent positioning and reset effects. Preferably, one end of each size indicating portion 23 tapers radially outward and includes two slopes 231 , each of the slopes 231 abuts against the positioning member 30 and slides into the positioning groove 32 when the holding member 20 is switched. In detail, when the positioning member 30 is moved or the holding member 20 is rotated, a slope 231 of the dimension indicating portion 23 can move against the positioning member 30 so that the second positioning portion 31 is separated from the positioning groove 32, and When the holder 20 continues to be rotated, the slope 231 of the other dimension indicating portion 23 can move against the positioning element 30 so that the dimension indicating portion 23 is automatically snapped into the positioning groove 32 (Figure 5 to Figure 9), and the operation is extremely Convenient and fast.
