[0013] In Fig. 1 Figure 1 shows a first embodiment of a tool device 100 in a side view. The tool device 100 comprises a drive module 110, an energy setting module 120, and a magazine module 130, wherein the magazine module 130 is detachably inserted into the energy setting module 120, and wherein the energy setting module 120 is detachably inserted into the drive module 110. In embodiments not shown, for example, the drive module is inserted into the energy setting module or the energy setting module into the magazine module.

[0014] The tool device 100 is designed as a setting device for setting fasteners (not shown) such as nails, bolts, rivets, and the like. It comprises a driving element (not shown), for example, a setting piston, for transferring energy to the fastener being driven, and a power-driven drive unit (not shown) for driving the driving element. The first module 110 comprises a housing 140, the drive unit housed in the housing 140, and a guide cylinder for the driving element, also housed in the housing 140. The second module 120 comprises an operating element 150, and the magazine module 130 comprises a driving channel in which a fastener is driven by the driving element in a setting direction 160 into a substrate (not shown), for example, made of steel, concrete, or wood, as well as a magazine 170 for feeding fasteners into the driving channel.

[0015] The drive unit comprises, for example, a powder- or gas-operated combustion chamber, a compressed air-operated pressure chamber, a mechanical or pneumatic drive spring, or an electrically operated flywheel. The driving force to be transferred to the fastening element can be adjusted using the control element 150.

[0016] In Fig. 2 A magazine module 200 with a magazine (not shown) is depicted. The magazine module 200 comprises a plug-in part 210, which fits into a plug-in receptacle 310 along a plug-in axis 230 defining a plug-in direction 220 ( Fig. 3 ) is pluggable. The plug-in part 210 has several successive second projections 240 in the insertion direction 220, which are designed to engage a first projection 340 of the plug-in receptacle 310 in a locked position of the plug-in part 210 relative to the plug-in receptacle 310 ( Fig. 3 ) to engage behind. In a circumferential direction around the plug axis 230, between the second projections 240, the plug part 210 has second gaps 250, which are designed to allow the plug part 210 to pass the first projections 340 of the plug receptacle 310 along the plug axis 230 when it is in a passing position relative to the plug receptacle 310. The plug part 210 is rotatable in the plug receptacle 310 between the locking position and the passing position in a rotation direction 260 around the plug axis 230. The second projections 240 are arranged one behind the other in the plug direction 220 and next to each other in the rotation direction 260. In the present embodiment, the second gaps 250 are offset from each other by 45° along the rotation direction 260, so that a total of eight different passing positions are provided along a circumferential direction around the plug axis 230.

[0017] In Fig. 3 A drive module 300 with a drive (not shown) for a drive element (not shown) guided in a guide cylinder 370 is shown. The drive module 300 includes a plug receptacle 310 into which a plug part 210 ( Fig. 2 ) can be inserted along a plugging axis 330 defining a plugging direction 320. The plug receptacle 310 has several successive first projections 340 in the plugging direction 320, which are designed to engage a second projection 240 of the plug part 210 in a locking position relative to the plug receptacle 310. Fig. 2 ) to engage behind. In a circumferential direction around the insertion axis 330 between the first projections 340, the insertion receptacle 310 has first gaps 350, which are designed to allow the second projections 240 of the insertion part 210 to pass along the insertion axis 330 when the insertion part 210 is in a passing position relative to the insertion receptacle 310. The insertion part 210 is rotatable in the insertion receptacle 310 between the locking position and the passing position in a rotational direction 360 around the insertion axis 330. The first projections 340 are arranged one behind the other in the insertion direction 320 and next to each other in the rotational direction 360.

[0018] In Fig. 4 Figure 400 shows a cross-sectional view of a plug-in part 400, which can be inserted into a plug-in receptacle (not shown) along a plug-in axis 430 defining a plug-in direction 420. The plug-in part 400 has several successive second projections 440 in the plug-in direction 420, which are designed to engage behind a first projection of the plug-in receptacle when the plug-in part 400 is locked relative to the plug-in receptacle.

[0019] The second projections 440 each have a second flank 480 rising along the insertion axis 430 on their side facing away from the insertion direction 420. The second flanks 480 become steeper from one second projection 440 to the next, opposite to the insertion direction 420. This distributes forces acting between the plug-in part 400 and the plug receptacle more evenly across the individual second projections 440. Furthermore, the second projections 440 increase in height h, radial to the insertion axis, from one second projection 440 to the next, opposite to the insertion direction 420. This ensures that the plug-in part 400 can only be rotated about the insertion axis 430 relative to the plug receptacle if it is inserted to the desired depth.

[0020] In Fig. 5 The figure shows a section of a plug-in part 500 and a plug-in receptacle 510, wherein the plug-in part 500 can be inserted into the plug-in receptacle 510 along a plug-in axis 530 defining a plug-in direction 520. The plug-in receptacle 510 has several successive first projections 541 in the plug-in direction 520. The plug-in part 500 has several successive second projections 542 in the plug-in direction 520, which are designed to engage behind a first projection 541 of the plug-in receptacle 510 when the plug-in part 500 is locked relative to the plug-in receptacle 510.In a circumferential direction around the plug axis 530, between the first 541 and second projections 542, the plug receptacle 510 and the plug part 500 have first 551 and second gaps 552, respectively, which are designed to allow the plug part 500 to pass the second 542 and first projections 541 along the plug axis 530 when it is in a passing position relative to the plug receptacle 510. The plug part 500 is rotatable in the plug receptacle 510 between the locking position and the passing position in a rotational direction 560 around the plug axis 530.

[0021] The first projections 541 and the second projections 542 are arranged one behind the other in the insertion direction 520. The first projections 541, furthest forward along the insertion axis 530 towards the plug-in part 500, each have two first insertion ramps 561 inclined towards the direction of rotation 560. This facilitates finding the correct insertion position when inserting the plug-in part 500 into the plug-in receptacle 510. Similarly, the second projections 542, furthest forward along the insertion axis 530 towards the plug-in receptacle, each have two second insertion ramps 562 inclined towards the direction of rotation 560.

[0022] In Fig. 6 Figure 600 shows an exploded view of a section of a tool device 600. The tool device 600 comprises a drive module 610 and a magazine module 620, detachable from the drive module 610, containing a magazine 625. The drive module 610 has a plug-in receptacle 630. The magazine module 620 has a plug-in part 650 that can be inserted into the plug-in receptacle 630 along a plug-in axis 640. The plug-in part 650 can be rotated in the plug-in receptacle 630 in a direction 660 between several alternating locking and passing positions about the plug-in axis 640. The plug receptacle 630 has first projections (not shown) and the plug part 650 has second projections 670, wherein in the locking position the second projections 670 engage behind the first projections in the direction of the plug axis 640 and in the passing position the first projections allow the second projections to pass in the direction of the plug axis 640.

[0023] The tool device 600 has a locking device 680 with a locking position and an unlocking position, wherein the locking device 680 prevents the magazine module 620 from being removed from the drive module 610 in the locking position and allows it in the unlocking position. The locking device 680 comprises a bolt 690 arranged on the magazine module 620 and a plurality of bolt receptacles 710 arranged on the drive module 610. Fig. 7 ) having connecting element 700. Furthermore, the locking device 680 has an actuating element 695 rigidly connected to the bolt 690.

[0024] Furthermore, the tool device 600 has a locking device 720 with two locking elements 730 and a plurality of locking receptacles 740, wherein the locking elements 730 each engage in one of the locking receptacles 740 when the plug-in part 750 is in the locked position relative to the plug-in receptacle 730. The locking elements 730 are arranged on the plug-in receptacle 630 and thus on the drive module 610, whereas the locking receptacles 740 are arranged on the connecting member 700. The locking elements 730 are designed as balls, which are arranged in ball receptacles 770 in the plug-in receptacle 630 and are biased inwards onto the connecting member 700 by an external ring spring 780. In embodiments not shown, one or more locking elements are provided on the drive module or the connecting member, as well as one or more locking receptacles on the connecting member or the drive module.

[0025] Furthermore, the tool device 600 has a safety device 750 with a secured position and an unlocked position, wherein the safety device 750 prevents activation of the tool device 600 in the secured position and permits activation in the unlocked position. An unlocking interlock 760 of the safety device 750 blocks a transition of the safety device 750 from the secured position to the unlocked position in the pass position and releases it in the locked position. The unlocking interlock 760 comprises several first locking elements 761 arranged on the drive module 610 and several second locking elements 862 arranged on the connecting member 700. Fig. 8 ) wherein the first blocking elements 761 and the second blocking elements 862 block each other in the passing position and allow each other to pass along the plug axis 640 in the locking position.

[0026] In Fig. 7 The connecting element 700 is shown, which is designed as a connecting ring 790 and has a circumferential groove 795 in addition to the locking receptacles 710, in which the detent receptacles 740 are arranged. When the connecting element 700 is rotated relative to the plug receptacle 630 in the direction of rotation 660, the detent elements 730 run in the groove 795 and engage in the detent receptacles 740 when the plug part 650 is in the locked position relative to the plug receptacle 630. The connecting element 700 is rotated together with the plug part 650 via the locking device 680.

[0027] In the Fig. 8, 9 and 10The magazine module 620 is shown together with the bolt 690 and the connecting element 700, with obscuring parts of the magazine module 620, such as the plug-in part, not shown, so that a drive channel 800 in the magazine module 620 is visible. The bolt 690 engages with a bolt extension 691 radially outwards with respect to the plug-in axis 640 into one of the non-visible bolt receptacles of the connecting element 700, so that the locking device 680 is in a locked position. The locking device 680 comprises a bolt spring 810, which biases the bolt 690 and the bolt receptacle towards each other, so that the locking device 680 is held in the locked position.

[0028] In the locked position according to Fig. 8 The locking device 680 prevents the plug-in part from shifting relative to the plug-in receptacle along the plug-in axis and from rotating the plug-in part in the plug-in receptacle about the plug-in axis. However, rotation of the magazine module 620 relative to the drive module 610 is possible, whereby the connecting element 700 rotates with the magazine module 620 from one detent position of the detent device 720 to the next when the locking device 680 is in the locked position.

[0029] In Fig. 9 The magazine module 620 and the connecting element 700 are shown in another such detent position of the detent device 720. The locking device 680 is still in the locked position.

[0030] In Fig. 10 The magazine module 620 and the connecting element 700 are shown after the actuating element 695, and thus the bolt 690, has been moved radially inwards against the force of the spring with respect to the plug axis 640. The bolt extension 691 has thereby moved out of the bolt receptacle, so that the locking device 680 is now in the unlocked position. In the unlocked position, the locking device 680 allows the plug part to be moved relative to the plug receptacle along the plug axis and to be rotated in the plug receptacle about the plug axis, so that the magazine module 620, by rotating in the direction of rotation, turns the plug part relative to the plug receptacle into the passage position, after which the magazine module 620 can be pulled out of the drive module.

[0031] During the transition from the unlocked position to the locked position, the bolt 690 moves radially outwards with respect to the axis of insertion into the bolt receptacle. In embodiments not shown, during the transition from the unlocked position to the locked position, the bolt moves radially outwards with respect to the axis of insertion or along the axis of insertion into the bolt receptacle.

[0032] In Fig. 11 The bolt 690 is shown with the bolt extension 691 and a stop 692, which, in the unlocked position, rests against one of the blocking elements 862 when the magazine module 620 is rotated into the passage position. The actuating element 695 is rigidly connected to the bolt 690 and forms an integral element with it.

[0033] In Fig. 12 A drive module 1200 of a tool is shown in section. The drive module 1200 has a plug-in receptacle 1210 with several first projections 1240. A plug-in part of another module of the tool can be inserted into the plug-in receptacle 1210. The drive module 1200 includes a lock 1260, which is located in the Fig. 12 In the normal position shown, a plug-in part inserted into the socket 1210 is secured against rotation relative to the socket 1210. A push button 1250 is rigidly connected to the lock 1260 and must be pressed to rotate the plug-in part in the socket 1210 and remove the further module from the drive module 1200. The drive module also has a first directional arrow 1270.

[0034] In Fig. 13 An operating module 1300 of a power tool is shown. The operating module 1300 has a plug-in part 1310, which has second projections (not shown) that engage behind the first projections 1240 of the drive module 1200 ( Fig. 12 ) are provided when the plug-in part 1310 is inserted into the plug-in receptacle 1210 and rotated relative to the plug-in receptacle 1210. The operating module 1300 includes an adjusting sleeve 1330 with which the driving energy of the tool can be adjusted. For this purpose, the adjusting sleeve carries an energy scale 1340. Furthermore, the operating module includes a clamping spring 1350 and a spring bearing 1360 for supporting the clamping spring 1350. The spring bearing 1360 carries a second indicator arrow 1370, which corresponds to the first indicator arrow 1270 of the drive module 1200 ( Fig. 12 ) must come into cover so that the operating module 1300 can be attached to the drive module 1200 in the desired position.

[0035] In Fig. 14 The operating module 1300 is shown without the adjusting sleeve. Below the adjusting sleeve, the operating module 1300 has a locking element 1400 and a support element 1410, wherein the locking element 1400 has an outer locking contour 1420 pointing towards the drive module 1200 and an inner locking contour 1430 pointing away from the drive module 1200. The drive module 1200 has a counter contour 1280 pointing towards the locking element 1400, wherein the outer locking contour 1420 engages in the counter contour 1280 when the locking element 1400 is in a locked position, in order to prevent rotation of the operating module 1300 relative to the drive module 1200. The support element 1410 has a support contour 1440.

[0036] In Fig. 15 The operating module 1300 is shown in section, with the support member 1410 in a holding position. In the holding position, the support contour 1440 supports the inner locking contour 1430 in the direction of the plug axis in order to hold the locking member 1400 in the locked position.

[0037] In Fig. 16 The operating module 1300 is shown in section, with the support member 1410 in a release position. In the release position, the support contour 1440 allows the locking member 1400 to disengage from the locking position along the plug axis.

[0038] The support member 1410 can be moved from the holding position to the release position by rotating the support member 1410 relative to the locking member 1400 about the stub axis. The inner locking contour 1430 and the support contour 1440 have insertion chamfers 1470 to facilitate the movement of the support member 1410 from the release position to the holding position. In addition, the outer locking contour 1420 ( Fig. 14 ) and the counter contour 1280 ( Fig. 12 The operating module 1300 has release ramps 1425 and 1285 to facilitate the release of the locking element 1400 from the locked position relative to the drive module 1200. Furthermore, the operating module 1300 has a first support spring 1450 and a second support spring 1460, which preload the support element 1410 relative to the locking element 1400 into the holding position.

[0039] When the adjusting sleeve 1330 is rotated around the shaft, depending on the direction of rotation, either the first support spring 1450 or the second support spring 1460 is compressed, so that the support element 1410 is moved into the release position against the spring force of the first or second support spring 1450, 1460. Now the locking element 1400 can disengage from the locking position and, in turn, rotate relative to the drive module 1200. Thus, energy adjustment is possible with one hand while the other hand holds the drive module 1200.

[0040] The locking element 1400 can engage in several detent positions of the counter contour 1280, allowing for the setting of multiple energy levels. As soon as the locking element 1400 is engaged in one of the detent positions or the operating sleeve 1330 is released, the support spring 1450, 1460 pushes the support element 1410 back into the holding position according to Fig. 15 , so that the locking element 1400 is itself held in the engaged locking position. In addition to the various energy levels, the locking element 1400 also has a disassembly position in which the operating module 1300 can be detached from the drive module 1200.

[0041] In Fig. 17 The operating module 1300 is shown in section. The operating module 1300 comprises a plug-in part 1700 with several secondary projections 1710. The plug-in part 1700 has a cam 1720 in which the lock 1260 runs when the plug-in part 1700 is rotated relative to the drive module 1200 until it reaches an end stop 1730, which corresponds to the disassembly position of the locking element 1400 and in which the operating module 1300 can be removed from the drive module 1200.

[0042] In Fig. 18 The drive module 1200 is shown in a partial cross-sectional view. A pressure cam 1800 between the operating module 1300 and the drive module 1200 prevents the tool from being pressed against and triggered in the disassembly position, while allowing the tool to be pressed against and triggered in each of the operating positions (energy levels).

[0043] In the Fig. 19 und 20 Figure 1900 shows a tool unit with a drive module 1910 and a magazine module 1920 that can be detached from the drive module 1900. The magazine module 1920 includes a plug-in part (not shown). The drive module 1910 includes a plug-in receptacle (not shown), which is in a basic position according to... Fig. 20 a triggering of the tool device is prevented and it is in a contact position according to Fig. 19 This allows the tool to be triggered. Pressing the magazine module 1920 against the drive module 1900 moves the plug-in holder into the contact position in the direction of a plug-in axis 1930.

[0044] The drive module 1910 comprises a clamping locking element 1940, which moves along the plug-in axis 1930 with the plug-in receptacle, and a clamping blocking element 1950. The clamping locking element 1940 is rotatable about the plug-in axis 1930 between a normal position and a disassembly position relative to the plug-in receptacle. The clamping locking element 1940 has a clamping locking contour 1960, the movement of which along the plug-in axis 1930 is blocked by the clamping blocking element 1950 when the clamping locking element 1940 is in the disassembly position. The clamping blocking element 1950 thus allows the plug-in receptacle to be moved into the clamping position only when the clamping locking element 1940 is in the normal position. In the disassembly position of the clamping locking element 1940, the clamping blocking element 1950, however, blocks the plug-in receptacle from being moved into the clamping position.

[0045] In order for the pressure locking element 1940 to rotate with the magazine module 1920, the pressure locking element 1940 has a drive contour 1970 and the magazine module 1920 has a driver 1980 which engages in the drive contour 1970 when the plug part is inserted into the plug receptacle.

[0046] A rotation of the plug-in part from the locking position to the pass position causes the pressure locking element 1940 to rotate from the normal position to the disassembly position. Likewise, a rotation of the plug-in part from the pass position to the locking position causes the pressure locking element 1940 to rotate from the disassembly position to the normal position. The pressure locking element 1940 is designed as a sleeve arranged around the plug-in axis 1930.

[0047] The invention has been described with reference to several exemplary embodiments of a driving device for fasteners. It is understood that all features of the individual exemplary embodiments can also be implemented in a single device in any combination, provided they do not contradict each other. It is also noted that the invention is suitable for other applications, in particular for screwdrivers or rotary hammers and the like.
