Definitions

• the invention relates to a tool for placing a threaded part, in particular a nut, in an area that is difficult to access, for example within a
• Such a tool is known from US Pat. No. 5,052,253, which is used to engage a screw with its slot at the tip of the screwdriver by means of a sleeve pushed over a screwdriver and to hold it in this position in order to hold this screw in a deep bore screw into a thread.
• the axis of the screwdriver is identical to the axis of the screw.
• the invention has for its object to provide a simple tool that is suitable for a Place the threaded part, for example a nut, the thread axis of which is perpendicular to the longitudinal axis of the tool, for screwing in a screw in an area which is difficult to access.
• the holding head has a groove-shaped recess running at right angles to its longitudinal axis, which, at least partially, non-positively receives the threaded part between its two opposing parallel surfaces in such a direction that the threaded axis runs perpendicular to the longitudinal axis of the holding head.
• the two opposing parallel surfaces have at least one spring holding the threaded part.
• the distance between the two opposing parallel surfaces of the recess can be changed.
• the holding head has at least one permanent magnet between the parallel surfaces, with at least one further permanent magnet being inserted on the end face of the holding head for pulling out a threaded part or another part.
• the holding head can be connected to one end of the guide rod via a connecting mechanism and thus can be exchanged for a further holding head with a different dimension.
• the length of the guide rod can be changed, in particular by means of tubes which can be telescoped into one another.
• a threaded part in particular a nut with a threaded axis running at right angles to the tool axis, can be placed in a region that is difficult to access without difficulty.
• Fig. 1 shows the side view (partially in section) of a tool according to the invention and next to the side view of a threaded part and Fig. 2 shows the view of the end face of this tool and next to it another side view of the threaded part.
• the tool according to FIG. 1 consists of a holding head 2 which receives a threaded part 1 and is secured against rotation, which is connected to one end of a guide rod 3, while the other end is provided with a handle 4.
• the threaded part 1 consists of a square nut to which a curved washer is welded, as shown in FIG. 2, and is therefore particularly suitable as a tension connector for connecting rafters of a roof truss to a crossbeam.
• a hole is drilled across the face of the rafters from the face of the rafters to the point where the nut with its curved washer should sit, transverse to the hole for the screw.
• this nut can easily be brought there by being brought in the direction of the arrows (FIGS. 1 and 2) to the holding head 2 and held in place by the attractive force of a first permanent magnet 7.
• the nut fits into a recess 5 and the curved washer into a further recess 12.
• the holding head 2 is released again, so that the tool can be easily pulled out of the bore.
• the holding head 2 has a groove-shaped recess 5 running transversely to its longitudinal direction, which receives the nut between its two opposing parallel surfaces 6 and holds it in place by the attractive force of the first permanent magnet 7.
• Another permanent magnet 11 is inserted on the end face of the holding head 2, with which, for example, a nut or the like lost in a blind hole or the like can be easily pulled out.
• the holding head 2 can be connected via a connecting mechanism 8 to one end of the guide rod 3 and can thus be exchanged for a further holding head 2 with a different dimension.
• the length of the guide rod 3 can be changed.
• it consists of two tubes 9, 10, which can be telescoped.
• the outer tube 9 is shown in section in Fig. 1, while the inner tube 10, which merges into the handle 4, is shown in the view.
• the handle 4 is suitably made of wood, plastic or rubber or it is coated with a layer of one of these materials so that it can be handled comfortably.
