Definitions

  • the invention relates to a hand tool with an auxiliary handle, which has a depth stop, in particular a hammer drill.
  • an additional handle is fixed with a clamp or a clamp or a strap on the clamping flange of a power tool.
  • a depth stop in the form of an intrinsically stiff, displaceable fixable rod is also arranged on this additional handle. With appropriate use of the depth stop on the workpiece surface and derives the entire contact force of the power tool, whereby the machining process, eg. The drilling is practically completed.
  • an auxiliary handle which can be set via an elastically biased clamping piece on the clamping flange of a power tool and has a clamping flange to the form-fitting matching head part, which is oriented at architecteeaidem definition of the axis of rotation of the power tool.
  • a polygonal intrinsically rigid rod is guided in this form-fitting axially displaceable fixable.
  • a clamping screw is used, which presses with its threaded bolt in tension directly on the rod and this frictionally determined. The trained by the threaded bolt contact surface is thus necessarily low and can lead to the application of a sufficient clamping force to plastic deformation on the rod, which in the future opposes a continuous depth adjustment.
  • an auxiliary handle which can be set by a turnable by turning the handle by means of a mallet tensioning strap on the clamping flange of a power tool and has a clamping flange to the form-fitting matching head part, which is oriented at architecteeaidem definition of the axis of rotation of the power tool.
  • a hexagonal intrinsically rigid rod in this form-fitting axially displaceable guided out is also known.
  • To determine the depth stop serves a transversely actuated to the axis of rotation, resiliently biased push button which forms a corrugated wedge surface, according to the EP1336446 a resiliently biased lever with a corrugated clamping surface that presses independently directly on an associated corrugated surface of the rod and thus determines this form-fitting and frictionally engaged.
  • the object of the invention is to realize a suitable for harsh use in construction down the depth stop a hand tool that can reliably derive the contact force of the power tool and yet does not damage the depth stop.
  • a hand tool on an additional handle with an oriented axis oriented to the working axis headboard in which a parallel to the working axis oriented rod guide for positively guided recording of a suitable as a depth stop, intrinsically rigid rod and a Verspannsch is arranged for at least partially frictional connection for this depth stop, which via a clamping screw along a Verspannraum transversely to the working axis is displaceable, wherein the bracing means has at least one clamping hole for the rod.
  • the hole edge By displaceable transversely to the working axis of the clamping hole through which extends the appropriate use of the rod, the hole edge partially forms the effective for clamping against the recording contact surface, which extends approximately over half the circumference of the rod and thus has such a large area to a sufficient to absorb the maximum contact force clamping of the rod material (eg. Steel) to remain in the elastic range, whereby no permanent plastic deformations arise.
  • the rod material eg. Steel
  • the auxiliary handle has at least one, more advantageously two, deposits with a voltage applied over a large area in the interior of the auxiliary handle bearing surface and a counter-clamping hole for the rod, which at least partially covered with the clamping hole of the biasing, whereby the inserted rod between the clamping hole and the counter-clamping hole is wedged elastically.
  • the insert is U-shaped with base and two legs and has in each leg a counter-clamping hole, which compared to two angular deposits a component is less required.
  • the legs of the U-shaped insert extend transversely to the clamping direction.
  • the bracing means is U-shaped with base and two legs and has a clamping hole in each leg, whereby the contact surface is increased and compensate for the bending moments of the angled legs.
  • the legs of the U-shaped tensioning means extend along the clamping direction.
  • the base (center) on an internal thread for the clamping screw, whereby the clamping screw is screwed directly into the bracing.
  • the Verspannsch and the insert made of metal, whereby high clamping forces without damage from the rod to the clamping screw can be transferred.
  • Fig. 1 has an additional handle 1, which is fixed to a clamping flange 2 of a hand-held power tool 3 shown in the form of a rotary hammer oriented to the working axis A, a clamping flange 2 to form fit matching head part 4, in which a parallel to the working axis A oriented rod guide 5 is arranged, which as a depth stop an intrinsically rigid rod 6 receives positively guided.
