Description

Technical field of the invention The present invention relates generally to driving tools and fastener magazines for these driving tools. More specifically, although not exclusively, the present invention relates to a driving tool comprising a magazine support arm equipped with a retaining means for attaching a fastener magazine to the magazine support. Technical background Magazine-feeding tools are known to include a magazine support arm with a locking mechanism to retain a magazine on the arm. Such a magazine-feeding tool is described in the document EP3822029 . Summary of the invention The present invention aims to provide a driving tool that is simpler and/or lighter and/or that allows for easier mounting and dismounting of a magazine on the tool. The invention relates to a driving tool comprising a retaining means for selectively retaining the magazine and a stop for limiting the recoil of the magazine when the driving tool is pulled. The retaining means may include a latch or latching mechanism, for example, a removable latch or latching mechanism, for selectively retaining the magazine. The latch will be referred to hereafter as a latching mechanism, but it is understood that this term may be replaced by latch. The retaining means may include the stop. The magazine-driving tool may include a magazine support arm. The arm may be equipped with a retaining means, for example, to retain a magazine to the arm; the retaining means or latch mechanism may be for selectively retaining the magazine against the arm. The invention also relates to a tool for driving fasteners, the tool comprising a magazine support arm having a retaining means for retaining a magazine to the arm, the retaining means comprising a releaseable latch mechanism for selectively retaining the magazine against the arm and a stop to limit the recoil of the magazine when the driving tool is pulled. The inventors found that by providing a stop and a separate release latch mechanism, the latch mechanism can be simpler than known locking mechanisms without compromising the reliability of the restraint means. The stop can be configured to stop or block the recoil or movement of the magazine, for example when the driving tool is pulled out. The means of restraint may include a restraint mechanism. The latch mechanism can be configured to slidably retain the magazine against the arm. The latching mechanism can be configured to press the magazine against a nose of the driving tool. The driving tool may include a nose, for example through which fasteners can be driven into a substrate. The magazine can be connected, for example during use, to the nose via a connection. The connection can be sliding. The latching mechanism can be configured to hold the magazine against the arm, for example when it slides along it during retraction. In some cases, the magazine is connected, during use, to the nose by a sliding connection and the latch mechanism is configured to hold the magazine against the arm as it slides along it during recoil. The sliding connection may include at least one pawn that can be received in an eyelet. The pawn(s) may depend on the nose, for example, to engage in the store. The store may include the eyelet. The stop can be configured to limit the sliding movement of the magazine along the arm during its recoil. The stop can protrude from the arm, for example to engage in an opening or recess in the magazine. More specifically, the stop can protrude from the arm to engage in an opening or recess in the magazine. The stop may be part of a plurality of stops. At least one or each of the stops may protrude from the arm, for example to engage in a respective opening or recess of the magazine. More specifically, the stop may be part of a plurality of stops, each protruding from the arm to engage in a respective opening or recess in the magazine. The latching mechanism can be mounted on the arm, for example near a distal end relative to the nose. The stops can be distributed along the arm and/or can be spaced away from the latching mechanism. Each stop may project from one side, for example a main side, of the arm. The arm may include an axis. The stops may be distributed along the axis of the arm. At least one, for example each, stop may include a stop surface. Each stop surface can be configured to engage the magazine, for example, to limit magazine recoil when the driving tool is pulled. Each stop surface can be substantially perpendicular to the arm axis. Each stop may include a wall, which may be perpendicular to the arm or to the axis of the arm. Each wall may provide the stop surface or one of the stop surfaces. Each wall may be reinforced, for example, by at least one rib that may extend from the wall on the opposite side of the wall to the stop surface, for example, along the axis of the arm. The latch mechanism may include a button to engage in the store. The button can be operated to release the magazine and remove it from the ar
