A position-limiting device forms a portion of a magazine assembly of a powder-actuated fastener-driving gun, and includes a nail-guiding pipe and a clamping unit. The nail-guiding pipe extends through a sleeve of a magazine assembly such that an end of the nail-guiding pipe is disposed outwardly of the sleeve. The nail-guiding pipe includes a tubular body, a nail passage hole formed in the tubular body and in spatial communication with the nail-receiving space in the magazine housing so as to allow one of the nails to be moved from the magazine housing into the nail-guiding pipe therethrough, and two aligned apertures formed respectively in two opposite sides of the tubular body. The clamping unit is disposed on the nail-guiding pipe, and extends through the apertures for clamping the one of the nails disposed within the nail-guiding pipe.

1. A position-limiting device adapted for a powder-actuated fastener-driving gun, the powder-actuated fastener-driving gun having a firing portion and a magazine assembly connected to the firing portion, the magazine assembly including a sleeve, a magazine housing connected to the sleeve and defining a nail-receiving space for receiving a row of nails, and a pusher movable within the magazine housing for pushing and moving the nails therewith, said position-limiting device forming a portion of said magazine assembly and comprising: a nail-guiding pipe adapted to extend through the sleeve such that an end of said nail-guiding pipe is disposed outwardly of the sleeve, said nail-guiding pipe including a tubular body, a nail passage hole formed in said tubular body and adapted to be in spatial communication with the said nail-receiving space in the magazine housing so as to allow one of the nails to be moved from the magazine housing into said nail-guiding pipe therethrough, and two apertures formed respectively in two opposite sides of said tubular body; anda clamping unit disposed on said nail-guiding pipe and extending through said apertures, said clamping unit being adapted for clamping the one of the nails disposed within said nail-guiding pipe. 2. The position-limiting device as claimed in claim 1, wherein said apertures in said nail-guiding pipe are converged toward each other, and each of said apertures has an inner end and an outer end opposite to said inner end and having a size larger than that of said inner end. 3. The position-limiting device as claimed in claim 2, wherein said clamping unit includes two clamping members confined respectively within said apertures in said nail-guiding pipe, each of said clamping members having a portion that is biased to project from a corresponding one of said apertures to press against the one of the nails and that has a volume smaller than that of the remaining portion of a corresponding one of said clamping members. 4. The position-limiting device as claimed in claim 3, wherein said clamping unit further includes a biasing member having two resilient arms pressing respectively against said clamping members, such that the one of the nails is clamped between said clamping members. 5. The position-limiting device as claimed in claim 4, wherein said nail-guiding pipe further includes a recess formed in an outer surface of said tubular body and in spatial communication with said apertures, said biasing member being received entirely within said recess and said apertures. 6. A powder-activated fastener-driving gun, the gun having a firing portion, a magazine assembly comprising: a sleeve having two opposite ends, one of which is adapted to be connected to the firing portion;a magazine housing connected to said sleeve and defining a nail-receiving space adapted for receiving a row of nails, and a pusher movable within said magazine housing for pushing and moving the nails therewith; anda position-limiting device including a nail-guiding pipe extending through said sleeve such that an end of said nail-guiding pipe is disposed outwardly of the sleeve, said nail-guiding pipe including a tubular body, a nail passage hole formed in said tubular body and in spatial communication with the said nail-receiving space in the magazine housing so as to allow one of the nails to be moved from the magazine housing into said nail-guiding pipe therethrough, and two apertures formed respectively in two opposite sides of said tubular body, anda clamping unit disposed on said nail-guiding pipe and extending through said apertures, said clamping unit being adapted for clamping the one of the nails disposed within said nail-guiding pipe. 7. The powder-activated fastener-driving gun as claimed in claim 6, wherein said apertures in said nail-guiding pipe are converged toward each other, and each of said apertures has an inner end and an outer end opposite to said inner end and having a size larger than that of said inner end. 8. The powder-activated fastener-driving gun as claimed in claim 7, wherein said clamping unit includes two clamping members confined respectively within said apertures in said nail-guiding pipe, each of said clamping members having a portion that is biased to project from a corresponding one of said apertures to press against the one of the nails and that has a volume smaller than that of the remaining portion of a corresponding one of said clamping members. 9. The powder-activated fastener-driving gun as claimed in claim 8, wherein said clamping unit further includes a biasing member having two resilient arms pressing respectively against said clamping members, such that the one of the nails is clamped between said clamping members. 10. The powder-activated fastener-driving gun as claimed in claim 9, wherein said nail-guiding pipe further includes a recess formed in an outer surface of said tubular body and in spatial communication with said apertures, said biasing member being received entirely within said recess and said apertures.
