Description of the Invention: [Technical Field] The present invention provides a nail-punching and braking device, in particular, capable of detecting the state of the __ remaining nail member, and gamma to control the device technology of the nail rushing.孜文全/月【前技术】 Press, nail gun brake firing device (or empty nails in order to be in the process of nailing, when the nail E is in a row of multiple turns) with 疋 can automatically detect the nail grab The nail slot is in a nailless state, and at the same time, the = machine is ineffectively pressed and cannot be turned (four) shape g, and the nail should be supplemented. On behalf of the author, the first traitor (four) firing device, can be seen in the national public movement and the safety slider corresponding to each other, push the nail piece can push against the row of the complex = nail: one by one into the human _ within the acceptance of the firing, and After being hit in the nail slot, the receiving pin is displaced in the direction of the nail slot, so that the brake piece is aligned with the pusher piece toward the safety slider position (the thickness of the nail piece) (4), for safety The slider is placed in the trough. ^ It can be moved up and down before being fired. It is designed to be the same as the movement of the female and the female (four). (4) (4) The distance from the nail, so that the 'old age piece pushes the nail After the last Yang piece of the nail slot (10) is fired, the pusher piece will be implanted in the nail slot, and (4) her position = = position = the position of the safety slide can be stopped, so that the safety slide is blocked by the brake Move up, and then generate the nail rushing system to remind the operator 201002483 that the author should refill the needle. In addition, most of the needles in the workshop use nails of smaller diameter, such as a nail called a mosquito nail. The thickness is about 1.2mm. 八,",,,, the above brakes are in the nail groove After the last nail member receives the firing, it can only displace the thickness of the last nail member (for example, 12 with the left and right). ^ The sliding rod causes the safety slider to accept the insufficient stop area! 2 = Used in the unknown nail slot There is no needle and strong pressure safety slider 2 =:, it is easy to cause the safety slider to be detached from the brakes. ' == "The actuation rate of the needle brake firing 4 needs to be improved. The door title is: In the prior art, the safety slider accepts a shortage of the stop area. It is a human brake. The purpose is to provide a 4τ grab brake firing, especially to the stopable safety slider. It can move up to the thickness of more than one piece of nails. According to the movement of the moving piece, the safety slide bar (4) is fully slippery to achieve the above purpose, and the nail of the invention is a safe slider; The set includes: a pusher piece, which is slidably disposed in one of the nails; a swinging rod, the elastic pivot is placed on the pusher piece, and the rod extends in the direction of the pusher to form a stop, and the piece is displaced and the pendulum a linear path of the stop portion, and the stopper portion is formed with a slanted guide plate formed between the full rods, located at the straight protrusion np, and the portion is offset from the straight path, and the end side can The guiding convex displacement is to cause the convex part to be disengaged from the guide plate, and the == push pin piece returns to the straight path stop 201002483 safety sliding rod, and the brake nail is used for smashing. According to the above, the stop portion is displaced to the position of the stop rod by a curved path' and the distance between the stop portion and the safety slider can be designed: = the distance between the piece and the nail slot of the nail grabbing, causing the stop portion The safety slide bar can be moved up by the area beyond the thickness of the support member to achieve the purpose of increasing the area of the safety slider of the finger stop, thereby improving the emptying rate of the needle. The movement mechanism above the safety slider is defined as driving the nail. In addition, the present invention also includes: a spring is disposed between the pusher piece and the swing rod, and is placed on the pusher piece. Holding the yellow π pendulum cup elastic pole, the guide plate is formed on the nail end side of the nail grab, and the guide plate and an outer inclined surface, when the stop portion approaches the safety slider along the linear path, the energy can be stopped The part deviates from the straight line. The = plate - the outer plane that engages the outer bevel, can be from the convex portion of the outer bevel to keep the stop away from the straight path. The plate has an inner bevel and is self-stopping at the stop. 复位 When resetting, the projection can be guided over the guide so that the stop portion connects the inner plane of the inner bevel to the side bevel. In the case of the line-time, it is possible to illuminate the convex portion to the inside. However, in order to clarify and fully describe the present invention, and to implement the example 0, the detailed description will be described later with the following description: 车乂佳201002483 [Embodiment] The present invention discloses an exploded perspective view of the needle-punching embodiment of the present invention, and the firing device is preferably placed in a --slot holder i and a nail.
