The magazine portion 5 has an end portion 5a that engages with the front end portion 3, and the other end portion of the magazine portion extends in a direction intersecting the extending direction of the front end injection hole 3& In the silo #5, a feeder 51 is mounted which is not only used to press the two or more connecting studs (connected fasteners) 15 loaded into the trough 5 from the other end into the front end. The perforating hole 33 is also used to move the remaining nail (fastener) 15 forward to the front end injection hole 3a after hitting the nail (fastener) 15 in the front portion of the front end. The feeder 51 is biased upward by one end h of the magazine portion 5 by a spring (not shown), whereby the feeder 51 always applies a connecting nail in the direction of the front end ejection direction 3a via its feeding portion 51a ( Fastener)15. Due to this structure 'When the loaded connecting nails (fasteners) 15 are sequentially struck and consumed, the feeder 51 faces the front end injection holes 3a forward (four) the remaining nails (fasteners) 15 and thus - pushes the remaining nails (fasteners) ) 15 and load it into the front end injection hole 123520-1010918.doc Λ ..

The lock arm 52 in Fig. 3 is extended from the one end portion to the other end portion, and the intermediate portion of the lock arm 52 inserted between the both end portions thereof is held by the front end portion 3 or held by the magazine portion 5. In order to hold the intermediate portion 52c, the retaining portion buckle is disposed in the front end portion 3 or the magazine portion using the -butment shaft 53', and the spring is similar to the spring end, and the spring is upward (in the direction) at the other end portion of the silo portion 5. The end of one end portion 5 of the biasing lock arm 52 is locked in the manner that the intermediate portion 疋 of the lock arm 52 is rotatable relative to the support shaft 53 provided in the front end portion 3 or the magazine portion 5, and As shown in _, the intermediate portion 52c is movable in the direction of the front end injection hole so as to be spaced apart from the intermediate shaft 53 by a distance d1. In particular, in order to move the lock arm 52 from the support shaft 53 in a state where the lock arm 52 and the support shaft 53 are separated from each other, in the intermediate portion 52c of the lock arm 52, the rotary slit portion 52f as shown in FIG. 4A or This rotating hole portion 52f is as shown in Fig. 4B. Each of them has an elliptical inner peripheral shape at least on the side of the front end injection hole direction, so that one end portion 52a of the lock arm 52 is movable in the direction of the front end injection hole, and the other end portion 52b is rotated as a result of With this configuration, the intermediate portion 52c of the lock arm 52 as shown in Fig. 12 can be moved from the first position P1 (where it is supported by the support shaft 53) to the second position P2 (where it is separated from the support shaft 53 by a distance d1).

Due to this situation, the push rod engaging portion 2〇c completely overlaps the top of the other end portion 52b of the lock arm 52, whereby the push rod engaging portion 20c is rotated into its full engagement with the other end portion 52b of the lock arm 52. status. In this state, even when the push rod 2 is pushed in the direction of the trigger lever, φ, that is, even when the push rod 2 is pressed against the workpiece (not shown), the push rod 20 is prevented from being in the rear position direction. The movement is because the other end portion 52b of the lock arm 52 exists in the moving path of the push rod 20. Therefore, the other end portion 20b of the push rod 2 is prevented from meshing with the arm plate 19, whereby the trigger valve portion 17A, i.e., the nail tapping operation of the driver piece 11, is stopped. When this state as shown in Fig. 8 occurs, 'if the feeder 51 is retracted (see '^1) and the fasteners (nails) are supplied into the groove 5' as shown in Fig. 3, the feed is engaged. The portion 51b abuts against the locking arm end portion 52a to remove its pressure, whereby the other end portion 52b of the locking arm is retracted from the moving path of the push rod 20 and returns to 123520-10iQ9i8.doc 17 1379745 in FIG.

This makes it impossible for the other end portion 20b of the push rod to engage with the trigger lever 18. Therefore, the trigger valve portion 17 cannot be activated, whereby the nail tapping operation of the driver blade 11 is stopped. In this state, since the remaining amount of the nail is a set amount (for example, 4), the push rod engaging portion 20c is loosely or weakly engaged with the other end portion 52b of the lock arm 52. Therefore, when the push rod 20 is pressed against the workpiece or the like without realizing that the remaining amount of the nail is a set amount, the shock or the like generated in the pressing operation is in some cases. Next, the engagement of the other end portion 52b of the lock arm can be removed. In the state in which the engagement is removed, when the trigger lever is pulled "to thereby activate the trigger valve portion 17, a nail tapping operation by the driver blade is possible. However, in this case, 'in the conventional nail In the drive machine, it is found that when the workpiece 20 or the like is applied to the push rod 20 in a state where the engagement of the other end portion 52b of the lock arm is removed, the plane surface portion of the push rod engaging portion 2〇c is related to the lock. The arm-end portion 52b is a choking portion (fulcrum), thereby preventing the lock arm-end portion 52a from rotating in the N direction. In other words, in the conventional nail driver, the feeder feed portion 5la is unlikely to be equal to or less The remaining amount of the nail of the set amount (four or less) is inserted into the front end injection hole 3a (in the financial direction). Therefore, the remaining amount equal to or less than the set amount cannot be borrowed. 51 is pressed to the correct position of the front end injection hole 3&, whereby the nails are present at the unstable position in the space between the feeder feeding portion 51a and the front end injection hole ^ in the magazine portion 5 when in X X X > ~山" " In the state of the unstable setting of the nail breaks When the perforation 3a strikes the driver piece u, the front & injection hole 3a or the like can be clogged with the nail, or the end portion 3 of the scratch. According to this issue I23520-l〇i〇9i8.d〇c § Amendment to the Emerald Moon Note ─ The above mentioned problems can be avoided for the following reasons. 4. Pressure-type tapping FIG. 11 shows a meshing state in which the tension state of the push rod 20 is maintained, that is, the pressed state of the push rod 2 is maintained in the pressed state of the workpiece 2 The tapping operation is performed, whereby the amount of the remaining nails 15 is reduced to the set amount (four). In other words, Fig. u shows a state in which the remaining nails 15 are reduced to the set amount (four) when a pressure type tap operation is performed while the workpiece is maintained in the pressed state of the push rod 20. In this state, the plane surface portion of the pressed push lever engaging portion 20c serves as an engaging portion (fulcrum) with respect to the other end portion 52b of the lock arm. In this case, since the inner peripheral portion of the rotary hole portion 52f is formed in an elliptical shape, the movement of the lock arm intermediate portion 52 (1 in the direction of 1) is not restricted by the support shaft 53. Fig. 12 shows a view similar to Fig. The condition shown imposes a condition of the compression type tapping operation, and in particular, the amount of the remaining nails 15 is reduced to a set amount or less (4 to 〇) of the salivation state. As described above, the pressed push rod is engaged The planar surface portion of the portion 2〇c serves as an engaging portion (fulcrum) with respect to the other end portion 52b of the lock arm and also because the lock arm intermediate portion 52C is not restricted by the support shaft 53 due to the elliptical rotary hole portion 52f but can be The holding makes it movable in the n direction, so the feeder feeding portion 51 a can always press the remaining nail 15 into the front end injection hole 3a direction (in the N direction). In other words, since the fulcrum of the locking arm 52 is from the fulcrum 53 Shift to the push rod engaging portion 2〇c, so the center of rotation of the lock arm 52 can be displaced from the intermediate portion 52c to the other end portion 52b; therefore, one end portion 52a of the lock arm 52 is in the N direction than in the feeder mesh portion The original setting position of the 5 can be moved further. 123520-1010918.
