The fastener supply passage 10 can be opened and closed by the door 8.

Secondly, the Cangjie 6 is mainly composed of the Cangjie body 4, the nail frame 12 and the guide post 13.

As shown in Figs. 2 to 4, the cartridge body 4 is composed of a cartridge body 4a and a cartridge cover 14, and the cartridge body 4a is constituted by a bottom portion 15a, a lower bottom portion 16a, and a semi-cylindrical portion 17a. Semi-cylindrical shape. The cartridge lid 14 also has a bottomed semi-cylindrical shape composed of an upper bottom portion 15b, a lower bottom portion 16b, and a semi-cylindrical portion 17b. That is, the cartridge body 4 is cylindrical, and a part of the cylindrical portion is constituted by the cartridge body 4a, and the remaining portion of the cylindrical portion is constituted by the cartridge cover 14. The fulcrum 18 is disposed on the lower bottom portion 16a of the cartridge body 4a, and the cartridge cover 14 is rotatably supported by the fulcrum 18. Thus, by rotating the cartridge cover 14, the cartridge body 4 is separated from the center and is largely open. The fulcrum 18 extends in a direction in which the bottom portion 16a below the cartridge body 4a extends.

The guide post 13 has a cylindrical shape and is disposed at a central portion of the cartridge body 4, and is rotatably supported at a central portion of the support shaft 18 of the cartridge body 4a, and is separated by a torsion coil spring 19 (refer to Fig. 8). The direction of the cartridge body is biased perpendicular to the lower bottom portion 16a of the cartridge cover 14. The lower portion of the guide post 13 is formed on the engaging piece 20 so as to be vertically engaged with the lower bottom portion 16b of the cartridge cover 14 as shown in Fig. 5.

The stud frame 12 is configured to erect the stud 22 at a central portion of the circular support member 21 on which the joint fastener 5 is placed, and the stud 22 is fitted to the outer side of the guide post 13 and supported to be vertically movable. slide.

When the cartridge cover 14 is closed, the outer peripheral edge of the support member 21 of the staple frame 12 supported by the guide post 13 comes into contact with the inner wall of the semi-cylindrical portion 17b of the cartridge cover 14 and stands vertically. Further, when the magazine cover 14 is rotated in the opening direction, the guide post 13 is also rotated together with the support shaft 18 to a predetermined angle. That is, the left side of Fig. 5 is the cartridge body side, the right side is the cartridge lid side, and the guide post 13 is inclined toward the right direction of Fig. 5. When inclined at about 50 to 60 degrees, the oblique side of the triangular lower projection 29 of the lower side of the fulcrum 18 hits the lower bottom portion 16a of the cartridge body, and the inclination is restricted. Therefore, when the fastener is placed on the staple holder 12, it stands with its weight toward the cartridge body 4a. At this time, the engaging piece 20 of the guide post 13 is engaged with the lower bottom portion 16a of the cartridge body 4a, and the outer peripheral edge of the support member 21 of the staple frame 12 comes into contact with the inner wall of the semi-cylindrical portion 17a of the cartridge body 4a, thereby becoming Upright state. When the cartridge cover 14 is rotated in the closing direction, since the engaging piece 20 of the guide post 13 is engaged with the lower bottom portion 16b of the cartridge cover 14, the guide post 13 is also integrally rotated, perpendicularly to the lower bottom portion 16a of the cartridge body 4a. Stand and keep the fasteners 5 attached.

According to the configuration of the magazine, when the fastener 5 wound in a coil shape is loaded into the magazine 6, the cartridge cover 14 of the cartridge body 4 is rotated downward about the spindle 18, and The cartridge body 4 is opened as shown in Fig. 2. At this time, since the staple frame 12 is inclined, the stud 22 is inserted into the center hole of the joint fastener 5, and the cartridge cover 14 is rotated in the upward direction, and is closed as shown in Fig. 1.

However, the staple frame 12 is rotatable about the guide post 13 and is configured to adjust the height position in the cartridge body 4 in response to the length of the fastener of the loaded fastener 5 by rotation. In other words, as shown in FIG. 4 and FIG. 5, in the guide post 13, the guide groove 23 in which the horizontal groove 23a and the inclined groove 23b are alternately formed in a spiral shape is formed so that the horizontal groove 23a and the inclined groove 23b face each other. Walls facing each other. The inclined groove 23b is provided at the front end of the fastening fastener 5 as the fastener is consumed, and since the fastening fastener 5 is rotated to the right as viewed from the top when the fastener is consumed, the inclined groove 23b is formed to face the horizontal groove 23a. Left side.

The extension 22a of the stud 22 is formed below the support member 21, the guide pin 24 is inserted into the extension 22a, and the guide pin 24 extends through the opposite guide groove 23 of the guide post 13.

When the nail holder 12 is rotated according to the supporting mechanism of the stud 22, the guide pin 24 slides along the guide groove 23. Although the height position of the staple frame 12 is the same when sliding along the horizontal groove 23a, when the sliding frame 23b slides along the inclined groove 23b, since the nail frame 12 also rotates upward or downward along with the guide groove 23, the height position thereof also changes. . In this embodiment, since the four horizontal grooves 23a are formed at intervals of 90, the height position of the adjustment nail holder 12 can be switched in four stages.

Further, on the inner wall of the cartridge body 4a, as shown in Fig. 6, the stamp indicates the scale 25 corresponding to the height position of the horizontal groove 23a. Thus, the nail holder 12 can be visually located at that height position.

Further, as shown in the seventh (b) of the support member 21 of the nail holder 12, the four height position indicating portions 26 are formed to protrude at equal intervals at equal intervals. The height position indicating portion 26 indicates the height of the support member 21 suitable for connecting the axial length of the fastener, and is positioned such that the horizontal groove 23a of the guide post 13 corresponds to the front surface, and the two height position indicating portions of the four portions correspond to each other. The manner in which the guide pin 24 is extended is preferably formed.

Further, since the support member 21 indicates the height adjustment position, the height position indicating portion 26 can be seen even when the connecting fastener 5 is loaded and the scale 25 of the cartridge body 4a is not seen when the fastener 5 is blocked. It is easy to adjust the staple frame 12 to the desired height position. Moreover, if it is used in a familiar manner, as shown in Fig. 6, since the distance H between the fastener head of the fastening fastener 5 and the upper bottom portion 15a of the cartridge body 4a is seen, the predetermined height position can be known sensibly. Therefore, it is not easy to adjust the scale without looking at the scale.

Further, since the height position indicating portion 26 is provided on the outer surface of the portion that protrudes downward from the support member 21, the connecting fastener does not come into direct contact, and since it does not wear, it can maintain a clear display.

Further, the height position indicating portion 26 may be formed on an end surface of the outer periphery of the support member 21 or a portion that is less likely to be in contact with the fastening member below the support member 21, and the shape thereof is not limited to the protrusion. For example, it may be a structure in which the end surface of the outer periphery is attached with a symbol.

Next, as shown in Fig. 7(a), the finger contact portion 27 for the rotational operation portion is formed on the outer periphery of the support member 21. This finger contact portion 27 is preferably constructed by using a concave surface or applying a slip prevention in order to prevent the finger from slipping. According to this configuration, since the finger can be attached to the finger touch portion 27 and rotated when the height position is adjusted after the connection fastener 5 is loaded, the turning operation can be surely performed. By providing the finger touch portion 27 to the height position indicating portion 26, it is possible to know whether or not the nail holder 12 is located at the adjustment position based on the position of the finger.

Further, the finger contact portion 27 is not limited to the outer periphery of the support member 21, and the finger contact portion 27a may be formed on the stud 22 as shown in Fig. 7(b). The shape is also not limited to the one shown.

Further, the cartridge cover 14 may be configured to be rotatable relative to the cartridge body 4a in the lateral direction. (In this case, the rotation axis of the cartridge cover 14 is orthogonal to the bottom surface of the cartridge body 4a.)

Next, in the case where the connecting fastener 5 wound in a coil shape is loaded in the magazine 6, as described above, in addition to opening the cartridge cover 14, the door 8 of the head 7 is opened, and the cartridge body is pulled out. 4, the front end side of the interlocking fastener 5 accommodated, although the front fastener is received inside the ejection opening 9 of the head 7, the operation of closing the door 8 and the cartridge cover 14 must be performed, but since it is made with one hand Simply operate, so the steering of the cartridge cover 14 is set as follows.

That is, as shown in Fig. 8, the support shaft 18 that supports the magazine cover 14 to be rotatable is disposed to form a fixed angle α with respect to the feeding direction of the joint fastener 5. This angle α is an angle at which the cartridge cover 14 is inclined toward the head 7 side as it rotates in the opening direction, and is approximately 15° to 30°. In addition, Fig. 8 is a bottom view of the magazine 6.

In the case where the fastening member 5 wound in a coil shape is loaded into the magazine 6 by the opening and closing mechanism of the magazine cover 14 having the above configuration, first, the door 8 of the head portion 7 is opened to open the fastener supply passage, and at the same time, the cartridge is opened. The cartridge cover 14 of the cartridge body 4 is rotated downward as shown in Fig. 9 around the spindle 18 to open the cartridge body 4. At this time, since the support shaft 18 of the cartridge cover 14 forms a fixed angle with respect to the feeding direction of the fastening fastener 5, as shown by the arrow of FIG. 8 as compared with the case where the support shaft is set in the feeding direction, As the cartridge cover 14 is rotated toward the opening direction, its upper bottom portion 15b is gradually inclined to approach the head portion 7 (left side in the drawing). The cartridge cover 14 also gradually approaches the door 8. Then, the center hole of the fastening fastener 5 is inserted into the stud 22, and the connecting fastener 5 is pulled out to the outside of the magazine 6, and the front fastener is received in the ejection opening of the head 7 while following the fastener supply path. 9. Then, the door 8 and the cartridge cover 14 are closed.

However, in the case of one hand (the right hand is the right hand), the fastener hitting machine A, and the other hand (left hand) is used for the loading operation of the fastener hitting machine A, and the left hand is opened as shown in Fig. 3 With the cartridge cover 14, the fastener 5 is housed in the magazine 6, and a part of the fastener 5 is pulled out, and the front fastener is housed in the ejection opening 9 of the head 7. Then, when the door 8 and the magazine cover 14 are closed, in order to prevent the front fastener accommodated in the ejection opening 9 from flying out due to the bending habit of the wire, as shown in FIG. 9, the fastener of the left hand is connected with the thumb of the left hand. The front end portion presses and holds the fastener supply passage 10, and then places the ring finger or the ring finger and the little finger on the back side of the bottom portion 16b below the magazine cover 14 in the open state, and shakes up the magazine cover 14 to the upper side. The light cartridge cover 14 made of synthetic resin is rotated about the support shaft 18 to be in a closed state. In this case, it is sufficient as long as it can be kept in the closed state. Next, the finger is moved away from the cartridge cover 14, and the thumb of the left hand still presses the front end side of the fastening fastener 5 under the fastener supply path, and the free index finger is wound around the head 7 side to close the door 8 with the index finger. After closing the cassette cover 14 and the door 8, it is only necessary to lock the two sides from the top.

Further, the method of closing the cartridge cover 14 is not limited to the above example. For example, instead of using a ring finger or a little finger, the wrist is placed on the magazine cover 14 and turned to close.

As shown above, the thumb of the left hand still presses the front end side of the fastening fastener 5 under the fastener supply path, and places the ring finger or ring finger and the little finger on the back side of the bottom 16b below the cartridge cover 14, because The thumb must be placed near the exit 9 of the head 7, so that the cartridge cover 14 is preferably located as close as possible to the head 7. Correspondingly, since the cartridge cover 14 is gradually inclined to approach the side of the head 7 as it rotates in the opening direction, the ring finger or the little finger can be easily placed on the cartridge cover 14 and closed properly when closed. .

According to the embodiment of the present invention, in the case of forming a magazine for supporting the fastener by sliding the nail holder in the up and down direction, the nail holder can be rotated around the guide post and can be adjusted by rotation. The height position of the nail holder can be adjusted by any position of the nail holder, so that the height position can be easily adjusted even after the fastening fastener is loaded.

Further, the guide groove in which the horizontal groove and the inclined groove are continuously spirally formed is formed so that the horizontal groove and the inclined groove face each other so as to penetrate the wall portion of the guide column facing each other while the guide pin penetrating the guide groove is formed. In the case of radially penetrating the stud, the stud can be supported at a high strength to rotate relative to the guide post, and the height position of the stud can be adjusted by the rotation at the position where the guide pin engages with the horizontal groove.

In the case where the finger contact portion for the turning operation is formed on the support member or the stud, the turning operation when the height position is adjusted after the connection of the fastening member is facilitated.

In the case where the height position indicating portion is provided on the outer periphery of the support member, even after the fastening member is loaded, the height position indicating portion can be seen to easily adjust the nail frame to an appropriate height position.

Further, the magazine cover is disposed at a bottom portion of the semicircular shape of the main body of the magazine to be rotatable about a support shaft disposed in a radial direction thereof, and the support shaft forms a fixed angle with respect to the feeding direction of the joint fastener, and if the cartridge cover Tilting to the side of the head as it rotates in the opening direction, holding the striker in one hand, closing the door and the cover of the magazine in the other hand, placing the thumb of the other hand on the head The front end side of the adjacent fastener is attached, and the front fastener is held so as not to fly out due to the bending habit of the thread, and the other fingers can be easily placed while the operation of closing the magazine lid is performed with other fingers.
