Definitions
- Attachable tool for attaching to an operating tool
- the invention relates to a plug-on tool with a plug-on opening for plugging onto an actuating tool, which has a substantially complementary profile to the plug-on opening.
- the invention further relates to an actuating tool which interacts with such an attachable tool.
- Actuating tool can e.g. be a torque wrench, i.e. an elongated part that allows the torque to be exerted on a screw connection.
- Different tools are used on such actuating tools for the different applications, for example open-end wrenches, ring spanners, creaking or kidney-joint parts. Open-end spanners or ring spanners directly engage the screw or nut.
- On ratchets or nierkant connection parts, e.g. Socket wrench inserts are used to grip the
- Screw or nut are formed.
- DE-U-76 24 918 is a tool set consisting of one
- Torque wrenches and insertion tools are known, which can be interchangeably attached to this, each insertion tool having a plug-in pin which is adapted to an insertion opening of the torque wrench and has a locking element.
- the plug-in pin of the plug-in tool and the plug-in opening of the torque wrench have a rectangular cross section, the large cross-sectional axis, i.e. the broad side of the rectangular plug-in opening, being arranged in the direction of rotation of the torque wrench .
- Attachment tools are also known which have a circular bore as a plug opening.
- the invention has for its object to improve the strength of the coupling between plug-on tool and actuating tool with the smallest possible dimensions.
- this object is achieved in a plug-on tool of the type mentioned in that the cross-section of the plug-in opening is essentially rectangular.
- the sides of the rectangle are in the rectangular cross section
- Attachment tool can achieve an optimal strength of the coupling between the actuating tool and the attachment tool.
- the tool is attached in a defined angular position, so that the parts of a detent mechanism provided on the attachment tool and the actuating tool, which secures the attached attachment tool against axial removal, are automatically aligned after being attached.
- the relative angular position of the plug-on tool and actuating tool is not defined by the shape of the plug-on opening.
- the actuating tool is formed by a square tube, on the outer contour of which the attachable tool can be attached with its attachment opening.
- the attachment tool is then placed directly on the outer contour of the actuating tool.
- Tool combinations of the present type which are set up for applying high torques with large attachable tools.

- the ring part 10 is seated on a shaft 14.
- the shaft 14 has an upper flat surface 16 in FIG. 1 and a lower flat surface 18 in FIG.
- the upper flat surface 16 is connected to the upper end surface 22 of the ring part 10 via an arcuate inclined surface 20.
- the shaft 14 is delimited by two side surfaces 24 and 26 which run obliquely towards one another from the ring part 10.
- the shaft 14 is somewhat wider than it is high.
- a push-on opening 30 with a rectangular cross section is formed in the end face 28 of the shaft.
- the broad side "a" visible in FIG. 2 is somewhat larger than the narrow side "b" visible in FIG.
- the larger broad side extends parallel to the plane of movement of an actuating tool interacting with the plug-on tool.
- aligned bores 32 and 34 are formed which are connected to the push-on opening.
- a locking member, which is provided on the actuating tool, can engage in one of these bores 32 or 34.
- FIG 3 and 4 show a plug-on tool designed as a reducer 36.
- the reducer 36 allows the use of existing small square tools in conjunction with one for rectangular ones
- the reducer 36 contains a head part 38.
- the head part 38 has a flat underside 40 and an upper side 44 which is inclined towards the end face 42 relative to the underside.
- An insertion opening 46 is formed in the end face 42.
- the insertion opening 46 takes a square 48 of an insertion tool, e.g. of a conventional square insertion tool 50.
- Square insertion tool 50 in turn has a square 52 at right angles to square 48.
- a socket wrench (not shown) can be plugged onto this square 52 in the usual way.
- the reducer 36 has a shaft 54.
- the shaft 54 has a rectangular shape
- FIG. 3 Cross section with an upper side 56 and a lower side 58 which is parallel thereto and adjoins the lower side 40 of the head part 38 in alignment.
- a rectangular push-on opening 62 is again provided in the end face 60 of the shaft 54.
- the push-on opening 62 corresponds in its dimensions to the push-on opening 30 of FIGS. 1 and 2.
- bores 63 and 64 corresponding to the bores 32 and 34 of FIG. 1 are provided on the upper and lower side of the shaft 54 in FIG. 3.
- the square plug-on tool 66 has a head part 68 with a square 70 and a shank 72.
- the shaft 72 has flat, parallel upper and lower surfaces 74 and 76 and an end surface 78.
- a push-on opening 80 with a rectangular cross section is formed in the end face 78.
- the push-on opening 80 is oblong-rectangular, the broad sides of the rectangle lying in planes that run perpendicular to the axis of the square 70.
- the square plug-on tool 66 with the plug-on opening 80 is plugged onto a substantially solid pin 86 of an actuating tool 88, which is essentially complementary to the plug-on opening and is elongate in rectangular cross section.
- the pin 88 includes a detent mechanism that cooperates with one of the holes 82 or 84.
- the detent mechanism includes a blind hole 90 in one
- the blind hole 90 is aligned with the holes 82 and 84.
- a cylindrical locking member 92 is guided in the blind hole 90.
- the locking member 92 has a locking projection 94 on its outer end face.
- the locking member 92 is under the influence of a coil spring 96 arranged in the blind hole 90 and is held in the blind hole by caulking.
- Latch projection 94 protrudes from blind hole 90.
- the catch projection 94 is pressed back against the action of the coil spring 96 and then snaps into one of the bores 82 or 84 on.
- the volume claimed by the catch mechanism is small compared to the volume of the square pin 86 of the actuating tool 88. The catch mechanism therefore does not lead to a substantial mechanical weakening of the pin 86.
- Fig. 9 and 10 show another embodiment of the actuating tool.
- the actuating tool 100 shown there can be used instead of the actuating tool 88 e.g. can be used as a tool combination in connection with a square plug-on tool 66.

- Square tube 102 engaging locking member 112 is arranged.
- the locking member 112 cooperates with a lateral bore (e.g. 84) of the plug-on tool 66.
- the detent mechanism 110 has a cylindrical pin 114 with a blind hole 116 in alignment with the lateral bore 108 of the square tube 102.
- This pin 114 extends both through the transverse bore 106 of the insert 104 and through the lateral bore 108 of the square tube 102 and thus secures the insert 104 in the square tube 102.
- the cylindrical locking member 112 is guided, which has a front surface Rastansatz 118 carries.
- the locking projection 118 protrudes through the lateral bore 108 of the square tube 102.
- the locking member is under the influence of a spring 120 seated in the blind hole 116 and is secured in the pin 114 by caulking.
