Description of the invention: [Technical field to which the invention pertains] 2 201114560 The present invention relates to a feeding mechanism for a connecting nail driving machine, which is directed from the feeding path of the fastening nail to the inside of the nail holder (four) The connecting buckles; and the contact arms include: = the head is sent out to slide freely, and the driving operation by pressing the driven member and the pressing of the button becomes effective. Further, the present invention relates to a connection pin, a fuel gas, and the like as a driving source, and the connecting pin driving machine includes a 7-milk structure, and is attached to the connecting pin-punching machine. When the nail is prevented from moving the nail in a direction opposite to the feeding direction, it is true [Prior Art] For example, in a high-pressure air drive of a nail-cylinder body using compressed air as a driving source, a supply collision is used.里擎居塞, and then use the impact of the drive, etc., impact from the nail ... knot the lower part of the body into the head of the injection 2: wide machine into the piece. The needle is driven into the joint, and the joint of the material contained in the (four) part is known to be between m/ and E. Nail exit. The feed of the nail. The needle feed mechanism is sent from the needle feed path to the reciprocating movement of the nail insertion passage Μ toward the nail feed direction. The passage is arranged: the feed claw is continuously fed. The feed claw is disposed on the rear side of the lamp shaft portion of the nail feed. When the feed claw is in the forward movement and the connection is made, the surface is back: the joint == the connecting nail: the feeding claw moves backward on the rear retracting surface, and the outer side of the π° nail feeding passage is repeatedly engaged with the next nail shaft portion. (refer to Patent Document 201114560 :::: At the time of the buckle operation of the machine, the buckle is always smashed and the safety device is placed. The contact f can be slid along the head. The contact arm two device includes the configuration protrusion. In the execution of the contact #, the part is more than the head, and the contact: the second end of the contact arm is pressed against the smashed /, τ nail machine body relatively moves, only at the upper end of the contact arm and the plate The machine is engaged with the nailing machine of the contact w. The nailing machine does not make the head ^ effective. The starting also becomes. τInjection, even if the shackle machine, the buckle operation becomes invalid, and the nailing machine is not activated (refer to Patent Document 2). The safety mechanism for loading the above-mentioned nail feeding mechanism or the contact arm is not only the Ding machine, but also the screwing machine that drives the wood screw. The mechanism has some kind of fault on the way of feeding the needle, or the hammer has not been sent. If the connecting nail is not sent to the normal / / 卩 ^ loading the normal position ' also if the contact arm action, can not be sent to the normal position, but start the nailing machine, the nail is blocked inside the head In order to improve this problem, a structure is also known (refer to the patent, which makes the feed claws longer to penetrate into the nail feed passage, and pushes the feed claw when nailing Swing to load in the normal position, and when the feed is not in the normal position, the contact arm interferes with the feed claw, and the contact arm cannot reach the top dead center without releasing the safety device. It is known that the connection of the metal wire is connected to the synthetic resin. As the connecting pin that is connected by the synthetic resin, it is known that the bending piece connection method and the flat piece connection method are required. The bending piece connection type 201114560 type connection buckle 4 is known. The outer side of the 6-phase m, and the other side of the reading section of the field are continuously bent to form the same nail holding piece, and the flat piece is evenly fitted to the nail holding piece. The support = buckle Nail's slender flat connection On the knot, the cross-over difference is set to *connected, "the narrow joint between the adjacent parts of the holding part is a connecting pin of a plurality of pieces of the production method of the tandem piece, and there is also a case of connecting the belt with the moon. , φ Μ , only the shaft portion of the pin is fitted to maintain the diameter of the yoke: the catheter is used. The catheter guides the pin to be in the mouth and does not tilt when it is pushed in. The connecting band is disposed on the catheter. The flat piece i is a car, and the s is up and down. Moreover, the type of the connecting stud is formed in a nearly straight shape. The line of the center = the connection part is set to 4 to 6). If it is based on ^ j , the line ^ is the side (see the joint document of the patent document Μ /T' because even if the synthetic resin is used to make the connection band Si: change : It can be wound into a coil shape, and at the same time, when the coil is wound into a coil shape, a plurality of fasteners can be loaded, and the side of the link belt of the patent documents 4 to 6 can be μ έ ' + ' a pin feeding mechanism that is placed in the connecting portion and is placed in the κ μ 料 结 打 打 打 m m m 设置 设置 设置 设置 设置 设置, Order for. The mechanism consists of the feed claw and the check claw. This feeds the relocation structure into the ',. The claws are reciprocated and moved in the direction of the nail feeding direction. When the forward movement is performed with the fasteners, the buckles are hit, and the masts are pressed; ^, P & and the injection exit side is pushed forward and the movement is reversed. The next pin is snapped. 5 The check claw prevents the feed claw from being engaged with the link when performing the retracting operation, so that the connecting pin and the feed claw are prevented from moving in the opposite direction to the feed. 201114560 However, as shown in Patent Document 3 The construction, although the feed of the nail is stabilized, but the operation of filling the nail, the claw length and making the swing. "To rotate the feed claw, use the connecting pin driver of the conventional flat piece connecting pin as shown above to engage the shaft of the catheter or the pin at the front end of the octagonal portion. The claw or the check claw may be such that the claw of the feed claw or the check claw and the catheter or the needle are stuck to the inside from the outer side of the joint belt and are engaged with each other, so that the movement is required to become large. The feed mechanism of the stud has to be made inconsistent: in particular, in the case of the check claw, the purpose is to keep the connecting pin from retreating, so that it is not necessary to specifically engage the shaft of the clasp. Thus, for example, In the outer edge portion on the side of the joint portion of the connection belt of the second embodiment of the patent document 4, the side of the nail holding portion and the side of the joint portion is formed by forming a concave portion having a fixed angle at the boundary between the arc portion and the straight portion. It is thought that the check claw is engaged with the concave portion. However, the angle of the _ portion is shallow 'excessively easing', and the towel stop claw may slide. Moreover, because the (4) part of the joint belt of the uth to the thirteenth figure of the document 4 is Straight line, the boundary has 2 positions, so it has a check claw at 2 Further, in the case of the connecting belt of Patent Document 5, the convex portion is formed in the nail holding portion. The convex portion is a center-cut strip which is formed into a line symmetry. The residual portion at the time of the break. Therefore, even if the convex portion is used to engage the check claw, the check claw does not necessarily engage with the convex portion, and as in the case of Patent Reading 4, there is also a nail holding portion and a joint. In the case where the recessed portion of the boundary portion of the portion is engaged, there is a possibility that the claw is engaged at two positions in 201114560, and the engagement is unstable. Further, although the connecting belt of Patent Document 6 is not a flat sheet type, in this case, In the same manner as in the case of Patent Document 5, there is a possibility that the check claws are engaged at two positions, and the engagement is unstable. Even when the same position of the feed claw and the joint belt is engaged, the occurrence occurs. In this case, in either case, even if it is intended to be used for feeding or non-return while maintaining the shape of the conventional connecting belt, the recess of the conventional connecting belt is not used for the engaging, so Unable to make even The feed or the check is stable. [Patent Document 1] JP-B2 - 283651 2 [Patent Document 2] JP-A-2005-081515 [Patent Document 3] JP-A-08-276378 [Patent Document 4] JP-A - 2009 - 115212 [Patent Document 5] JP-A - 2009 - 115213 [Patent Document 6] JP-A - 2009 - 264585 SUMMARY OF THE INVENTION The above embodiments of the present invention provide a connecting pin The driving machine's can make the feeding claws carry out (4) (4), and directly fill the connecting buckles when misloading the connecting nails or in the case of bad occurrence, the poor driving can prevent the driving action of the fastening nails. One or more embodiments of the present invention are provided with a tie pin driver that can have a snap fit.卩 or the type of the convex part of the joint is different. 201114560 The knot nails make the check claws common. According to an embodiment of the present invention, the "knot pushing drive mechanism includes: a feed passage (1) for the staple") a driving head (3) that opens to the lower portion of the nailer body (1); the feed claw (26) ' is engaged with the connecting pin (A) loaded in the feeding path (1), and is fed to the outlet (4) of the head (3) by moving in the feeding direction (A) The contact means (33) is arranged to slide freely along the head (3), and is moved relative to the nailer body (1) by pressing the driven member to cause the start of the fastening of the fastener The operation becomes effective, and the engaging portions (43, 53) are provided in the contact means (33)' and are engageable with the feeding claws (26). The feed claw (7) is configured to be retractable from the feed passage (11). The feed claw (2) is configured not to rotate the feed claw (2), and the joint pin (A) can be loaded in the feed path (n). In the advance, ·. When the claw (2) is retracted, the contact means (33) is pressed against the engaging portion (43, 53) of the stalk contactor (33) which is engaged with the feeding claw (2). In this configuration, if the connecting pin is normally loaded in the feeding path, since the feeding claw does not rotate to the outside, the feeding mechanism does operate and the nail is normally fed. Further, when the front end of the head is pressed against the driven member, the contact means is only moved by a sufficient amount, so that the starting operation of the trigger handle is also effectively performed, and the driving of the nail is normally performed. Relatively misaligned loading links! D, or "filling the claws that have not been properly engaged with the feed claws and forcibly closing the feed passage, since the joint push pins push the feed claws outward, the feed claws are retracted outward. The front end portion of the feed claw is moved to a position engageable with the contact means. In this state, the front end of the 201114560 contact means is slid by the hitting plant, and the engaging portion of the fish is further moved to move relative to the main body of the needle. The means of contact means are not effective, and it is impossible to make the nail hit and change to the head (4). The driving action 1 can prevent the nail from being blocked. The structure of the embodiment can also be the engaging portion (34) of the engaging portion (4) at the front end of the contact means (10). In this configuration, since the cylindrical contact top of the front end portion of the engaging portion portion and the contact hand are in the configuration of this embodiment, it is also possible to use a special engaging member. The k-card 5 is composed of a snap pin (Μ) located below the feed claw (2) in a state of retreating. In this configuration, since the engaging portion is formed by the engaging pin placed under the feeding claw of the retracting rotation, the engaging portion can be simply formed. The structure is attached to the two rows (1), and the engaging portion (43) may be formed as a movable head (55) at the front end of the means (33). = This configuration ' Since the engaging portion is formed as a movable head provided to the contact hand, it is not necessary to provide a special engaging member. Further, in accordance with the above embodiments of the present invention, the joining machine includes: a feed passage for the staples (1), a m ^ - ΤΓ ", and a nailing machine body under the rain. The driving head (3) of the ρ; the feeding claw (3)) is engaged with the connecting pin (1) loaded in the second way (1), and is moved to the head by moving toward the feeding direction (3) The injection port (4) sends out the connection (OQ \ , ;, and the check claw ', and restricts the movement of the connection pin (A) of the feed path (u) into the 201114560. A) 'A plurality of clips (a) are connected via the upper and lower connecting pieces (13), and the engaging recesses (14) or the engaging convex portions are formed on the respective sides of the upper and lower connecting pieces (13). In the feed passage (11), the upper and lower engagement recesses (14) or the plurality of connection buckles (a) having different intervals between the engagement projections can be individually loaded. The claw (26) or the pawl (28) is configured to be engaged with the upper and lower engaging recesses (14) or the engaging projections when any of the plurality of connecting clips (4) is used. (4) The structure of the embodiment is such that the 'feeding claw or the check claw is formed in any of a plurality of types of fastening nails', and the upper and lower engagement recesses (14) or the convex portion card Thus The form in which the check claw or the feed claw is engaged with the engaging portion is the same regardless of the type of the connecting nail. 'The check of all types of connecting nails constituting the system can be surely executed by the common check claw. The method is because it is not necessary to repair the various gentlemen's colds. The nails are replaced with the claws or the nailing machine is replaced, so that the overall cost can be restrained. The positional accuracy is obtained, so that the synthetic resin can be used to reduce the cost of the parts, and Moreover, since the check claw or the feed claw does not have to be formed by the sheet metal processing to form the check claw or the feed claw, the member supporting the check claw or the feed claw is supported.

The mechanism is actually operated, and the nail is fed normally. Moreover, when the front end of the head 3 is pressed against the hit member, the contact member is also moved by a sufficient amount, so that the hand 15 is also effectively performed. The starting operation is performed normally, and the driving of the nail is normally performed. In contrast, when the connecting nail A is mistakenly loaded or loaded, the claw portion 44 that is not engaged with the feeding claw 26 is correctly engaged, and the door 21 is forcibly closed. Since the door 21 pushes out the fastening pin A', the connecting pin A pushes the feeding claw 26 outward. Thus, the feeding claw 26 retreats outward, and the feeding claw 26 front end 42a

At this point, the front end of the contact member 33 is pressed against the driven member so that the joint 33 slides upward relative to the nailer body, because on the way: the front end portion of the claw 26 protrudes' Therefore, the engaging portion α and the inward: two: 6: the front end of the hand is abutted and cannot enter. The contact member 33 cannot be 'square: moving. If the movement of the contact member 33 is restricted, the shackle handle = the effect of the nail and the nail hitting action cannot be performed. If the second situation 1 is revealed, 26 will not advance to the forward end. Therefore, it can prevent the nail from being clogged in the head 3 (four). After Erliang may correctly fill the interlocking nail A, and the above-mentioned one or two squats, it will happen on the way 'but even in this case, the feed claw 26 is outward (four) Μ shift (four) dragon system (4) The knotted nail 2 contact member is given to the claw jaw, so it can be surely prevented from hitting the nailing action h to the outside or: 2 =! Each joint buckle 4TA, the height of the flying concave shaft of the engaging recess is different, However, the engaging recesses - a plurality of connecting buckles continuously formed in the direction of the nail axis can be combined. In this case, as shown in Fig. 14 (3), the same nailing machine can be used to fill the joint fasteners. Needle α, α,, :: The unloader can be individually: as long as it is non-returned... it becomes a card that can be connected with the two: _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ It suffices that the front engagement recess of the check claw 28 is larger than the maximum width map (b) between the upper and lower engagement recesses 14. The largest interval in B (for example, the 15 19 201114560 buckle) Because of the nail, it is possible to prevent the type of the joint when the fastener is fed. #二二利: The shared check claw 28 moves in the reverse direction. °The knob 戸, or the engaging portion is disposed to be inclined with respect to the nail axis. _ If the combination of the plurality of the claws 28 for the connecting claws as described above is used, the stop 28 can be shared. It is possible to replace the check claws 28 or (4) with various interlocking pins, so that the overall cost can be pi. Moreover, since the scale of the combination becomes larger, the effect is further increased. u (the last one) The front portion of the member (9) is formed in a zigzag shape, and the front end 31 of the check claw 28 is turned toward the side, and the side of the feed claw η is slightly curved, and as shown in Fig. 6 (4), the claw 26 is retracted. At the same time, as shown in Fig. 6 (end 31 and Lianshe Qizhi A mouth claw 28, j ^ ^. The triangular engagement recess 14 of the nail A of the connecting piece 13 is at the same time and the base of the check claw 28 is also connected. The side of the piece 13 is engaged. Therefore, the check claw 28 is hidden: ^, p, q card, and the center of the spacer 3 are at least two positions before and after the position After the nail of the second branch is finally started, when it is turned into 0D ^ D丨, 26 and returns to the rear of the last nail a, it passes over the side of the nail a - the surface is receded, but Because the check claw 28 is separated from the nail a # & Therefore, the check claws 28 are not detached from the engaging recesses 14 of the connecting nails A & the upper L, A, and the final nails & can also be fed reliably. On the phase, as shown in Fig. 6 (c ), if the front end of the pawl 28 is the same as the back of the nail, the rear part of the last nail 3 may be moved at 20 201114560. Back, and with the check claw 28, the engagement and the engagement of the recess U, the end and the mouth. P is the center rotation, and finally the check claw recessed portion 14 is detached, and δ is fed from the card toward the front. "There is no stopping action, so the last stitch (other form of the engaging portion)" "the engaging portion 43 of the human contact member 33 cannot be integrally formed and formed. Alternatively, the contact top 34 can also be constructed as shown in Fig. 7. That is, the μ-link to the trigger handle 15 is anchored. The main arm 46 of the upper contact member 33 is coupled with the guide 47 of the guide contact top 34 from the guide 47 of the dip direction, and the snap pin is engaged (the engagement is placed by the main arm 46) The lower end curved portion 50 of the jib 48 formed by the branching of the full 叱, ^ is disposed on the stitching 52 with the compression spring 53 that energizes the contact member 33 π + ur fine curved piece 33 downward. The feeding claw 26 of the upper side of the engaging pin 52, which is retracted from the rotation, can make the handle of the trigger 15 from the contact structure of the tree to be lower than the effective position. The basic structure of the institution is not the same as that of the above-mentioned form.

At this time, the right link* is loaded with the connection pin A, because the feed claw 26 does not turn a to the outside, so the feed mechanism does The action is also hoisting, sealing, and 'when the nail is pressed, when the front end of the head 3 is pressed against the driven member, also because the contact member 33 does not interfere with the feeding claw (9) The nailing machine body moves upwards, so the starting operation of the trigger 21 201114560 is also effectively performed. Therefore, the nailing is also normally performed. The two grounds are misplaced, and the nails are filled or interlocked. When the door 21 is properly closed and the door 21 is closed, " : = link..., and push it to the outside...:, 2::::::: Avoid the rotation. In order to enter the state, "contact the machine" "At the time of pressing under pressure, the contact member 33 is relatively moved upward relative to the nail.

The nail is blocked in the head 3. Therefore, it can be preliminarily (other forms of the contact member).

Also, when the feed mechanism is broken, the movable head 55 is not: the front end of the portion 3 is pressed against When the main body of the needle is moved upward, and the two jaws 26 interfere with each other, the starting operation of the gripper 15 is also effectively performed. Therefore, the nail is normally driven in. The opposite side is loaded with the stud. When the claw 44 of the 26 is correctly engaged, and the y is not properly engaged with the feeding claw and closes the door 21, as shown in the following: "Because the door 21 pushes the connecting pin A, it pushes outward. Pressing in: The kg is retracted to the outside by the feed claw 26. The front end of the head 3 is slid into the needle when the needle is inserted into the housing, and the body is relatively slid upward.
