Description

Technical Field

[0001] The utility model relates to a screwing tool for a socket head and a screwdriver head. Background Art

[0002] For example, document DE 10 2007 049 304 A1 describes a screwing tool of the aforementioned type. This screwing tool has a drive region, which can be designed, for example, as a handle, but can also be inserted into the chuck of an electric screwing tool. The drive region is connected to an output base in a torque-transmitting manner, and the output base has a size of 3 / 8 inch, 1 / 2 inch, or 3 / 4 inch. A socket head can be inserted into the output base, which has a receiving opening corresponding to the cross-section of the output base. The socket head has a polygonal opening that can accommodate different wrench widths and can be inserted onto a hexagonal screw head or hexagonal nut to apply torque thereto.

[0003] The prior art also knows screwing tools that have a drive area in the form of a handle and an output part in the form of an insertion opening for inserting the hexagonal section of a screwdriver bit. For example, document DE 10 2019 116 810 A1 describes such a tool that also has a tool magazine for storing screwdriver bits. Utility Model Content

[0004] The technical problem to be solved by the present invention is to expand the application scope of the aforementioned type of tools.

[0005] The technical problem is solved by a screwing tool.

[0006] First and foremost, it is proposed that the output base have an insertion opening on its end side, into which the drive shank of a screwdriver bit, such as a drill bit, can be inserted. Thus, the tool can be used both for screwing a socket head, which has a receiving opening into which the output base can be inserted, so that the outer circumference of the output base abuts against the corresponding surface of the receiving opening in a torque-transmitting manner, and for screwing a drill bit, which has a working tip, such as a cross-groove profile, and an output base having a drive shank, particularly one with a hexagonal profile, into which the drive shank can be inserted. The screwing tool is particularly advantageous when using a long socket head. Such a socket head has a first end, which forms a receiving cavity that can be inserted onto the output base. The receiving cavity is connected to an axial cavity with an inner polygonal opening, which is located at the second end of the socket head. The inner polygonal opening can be inserted onto a nut or screw for rotation. The output base engages with the receiving cavity. The inner polygonal opening and the receiving cavity are spaced apart to such an extent that a drill bit inserted into the insertion opening can be completely positioned within the socket head without interfering with the use of the inner polygonal opening to turn a nut or screw. The tip of the screwdriver bit is embedded to the greatest extent possible within the axial portion of the inner polygonal opening. Preferably, the screwdriver bit extends within the insertion opening without its working tip entering the area of ​​the inner polygonal opening. Therefore, when the screwdriver bit is inserted into the insertion opening, the socket head can be used to turn a screw head or nut. The axis of the insertion opening and the axis of the output base formed by the polygonal cylinder extend coaxially. The insertion opening preferably has a hexagonal cross-section measuring ¼ inch. The cross-section of the output base can be square and at least ¾ inch. In a refinement of the present invention, a magnetic fastener is provided to temporarily secure the socket head to the output base. The magnetic fastener temporarily secures the screwdriver bit in the insertion opening. Provision can be made for the output base to extend from the abutment surface. The abutment surface can extend in a plane, with the axis of the output base extending perpendicularly to the plane. This can be a plane extending on an annular surface that extends around the output base. The edge of the accommodating opening of the sleeve head can be in contact with the plane. A magnetic zone can be provided in the area of ​​the abutment surface. The magnetic zone can be formed by a permanent magnet. One or more permanent magnets can be arranged in a groove of the abutment surface. For example, two diametrically opposed holes can be provided in the abutment surface, in which permanent magnets are respectively installed. The insertion opening is preferably a blind hole with a hexagonal cross-section, and the insertion opening has a bottom plate forming the magnetic zone. The magnetic zone can also be formed by a permanent magnet forming the bottom plate of the insertion opening. It can be provided here that the permanent magnet forming the magnetic zone can be glued into the opening for accommodating the permanent magnet. However, it can also be provided that the permanent magnet is held in the opening for accommodating the permanent magnet by a form-fitting part. For example, a clamping ring can be provided, by which the permanent magnet is retained in the opening.The handle or head forming the output base can be shaped as described in the aforementioned prior art. For example, a cavity can be provided within the handle for the user to grasp. This cavity can contain a tool magazine for storing screwdriver bits or socket bits. The tool magazine can include a tool holder that can be pulled out of the handle cavity through a rear opening. In the storage position, the tool holder closes the opening at the rear end of the handle. In the removal position, the screwdriver bit or nut carried by the tool holder is exposed for removal. It can also be provided that the output base comprises a head that is pivotally connected to the handle or other drive area about a pivot axis. A locking element can be provided, by which the head can be locked. Furthermore, it can be provided that the head has a reversible freewheel mechanism, allowing the screwdriver to be used as a ratchet wrench. However, the drive area can also be a handle rigidly connected to the output base, extending along the axis of rotation. However, in an alternative embodiment, the handle can also extend transversely to the axis of rotation, and the output base can be associated with the freewheel mechanism.

[0007] The utility model also relates to a screwing tool having a tool magazine located in a cavity of a handle. The handle has a front end and a rear end, and the handle has a diameter that can be grasped by a user's hand. A device for inserting a screwdriver bit can be arranged at the front end. An opening is arranged at the rear end, through which the tool magazine can be pulled out from a storage position in the cavity to a retrieval position. The tool magazine has multiple recesses, each of which can be inserted into a screwdriver bit.

[0008] In the screwdriver described in document DE 10 2019 116 810 A1, the recess is arranged on the closure cap. The tool magazine has an axial length of slightly more than 25 mm, so that a 25 mm long screwdriver bit can be accommodated.

[0009] In order to further improve this screwdriver for advantageous use, it is suggested that the tool magazine has a tool holder having additional recesses for accommodating shorter screwdriver bits of 25 mm in length, or forming retaining tabs that respectively hold the shank of a longer screwdriver bit, the length of which can be 50 mm. The two tool holders are spaced apart from each other in the axial direction. The tool magazine can have a piston that is guided on the cavity wall within the cavity. The piston can have a radially acting tongue spring that rests against the cavity wall under the action of the spring preload. The tool magazine can have a central cavity into which a guide rod can be inserted in the storage position. When the tool magazine is removed from the cavity, the tool magazine can be guided on the guide rod. The tool magazine can be composed of a plurality of parts that are nested in each other. The individual parts are connected to each other in particular by axial plug-in connection, wherein the latching protrusions engage with the latching openings. According to this embodiment, the first tool magazine can be provided for storing shorter screwdriver bits, and the second tool magazine can be provided for storing longer screwdriver bits. The first and second tool magazines each have the same piston and the same closure cap. The first and second tool magazines differ only in a central part, which is connected to the piston and the closure cap by a latching connection, thereby forming a second tool holder having a recess or a retaining tab.

[0010] The present invention also relates to a plurality of screwdrivers, each comprising a handle having a handle cavity and a tool magazine inserted therein that can be pulled out from a storage position to a removal position, wherein the two tool magazines essentially have a piston and a closure cap of identical design, and differ in the tool holder inserted between the piston and the closure cap in that one tool holder is provided with a recess with a base, while the other tool holder is provided with only retaining tabs for enclosing the shank of a screwdriver bit. A further combination is provided in which the tool holder arranged between the closure cap and the piston has recesses each with a base at some radial positions and, at other radial positions, has only retaining tabs that can engage with the shank of a longer screwdriver bit.

[0032] The screwdriver shown in the figures has a handle 1 with a plastic cover, which can be gripped by the user's hand. Inside the handle 1 is a cavity 17, which is open to the free rear end of the handle 1 and into which a tool magazine 18 is inserted. The tool magazine includes a tool holder 19, which can support a plurality of socket heads 9 or screwdriver heads 14. A closure cap 20 is provided at the free end of the tool holder 19, which is inserted into the tool magazine 18. Figure 1 In the storage position shown, the rear opening of the cavity 1 is closed.

[0033] The end of the handle 1 opposite the opening of the cavity 1 carries a fork, with a head 21 located between the forks. The head 21 is rotatably connected to the fork about a pivot axis 22. Inside the handle is a latch 23, comprising an elongated pin that can be moved axially relative to the direction of extension of the handle 1 by operating a slide switch 27. The pin's top end forms a latching pin 25, which, in the locked position, engages one of several latching recesses 26 in the head 21, preventing the head 21 from rotating about the pivot axis 22. As shown in the figure, the head can be rotated to a position where axis A forms a 90-degree angle with the axis of extension of the handle 1, which determines the direction of extension of the output base 2. (Not shown in the figure, the head can also be positioned where axis A coincides with the rotation axis of the handle 1.) In these positions, the head 21 is rotationally locked by the latching element 23.

[0034] A switchable freewheel mechanism is provided inside the head, which can be switched by a switch 28 arranged opposite the output base 2. Thus, the screwing tool can turn screws or nuts clockwise and counterclockwise in the manner of a ratchet wrench.

[0035] In this embodiment, the output base 2 has the shape of a polygonal cylinder and in particular has a square cross section, which corresponds to a dimension of 3 / 8 inches.

[0036] The output base 2 extends from an annular surface surrounding the output base 2. This surface forms a contact surface 6, against which the edge 11 of the sleeve head 9 can rest when the sleeve head 9 is inserted into the output base 2 with its receiving opening 10. The contact surface 6 is provided with two or more, in particular opposite, holes. Permanent magnets 7 are inserted into these holes, which generate a magnetic force, thereby fixing the sleeve head 9 to the contact surface 6 or the output base 2. The sleeve head 9 can be removed from the output base 2 by applying an axial force that overcomes the magnetic force. The outer peripheral surface 2' of the output base forms opposite partial surfaces, which can rest against the surface of the receiving opening 10 in a torque-transmitting manner.

[0037] The output base 2 is constructed with an end side 4, which can be a flat end side surface extending parallel to the contact surface 6. However, the end side can also have a slight bulge. There is an insertion opening 3 in the center of the end side 4, which has a generally hexagonal cross-section. The size of the insertion opening 3 is preferably 1 / 4 inch. The hexagonal drive rod 15 of the screwdriver bit 14, for example, a drill bit with a working tip 16, can be inserted into the insertion opening 3. The base plate 6 of the insertion opening 3 is composed of a magnet 8, which exerts a magnetic force on the screwdriver bit 14 to prevent it from falling out of the insertion opening 3. The magnetic force can be overcome by a correspondingly high axial force, thereby pulling the screwdriver bit 14 out of the insertion opening 3. In this embodiment, the working tip 16 of the screwdriver bit 14 is in the shape of a cross groove. However, the working tip 16 can also have a flat profile, a Torx profile, a hexagonal profile or any other screwdriver profile.

[0038] Figure 7 The application of the screwing tool according to the present invention is shown. A screwdriver head 14 preferably about 25 mm long is inserted into the insertion port 3. A longer socket head 9 is inserted on the output base 2, and the socket head has a cavity 13, which is usually connected to the accommodating port 10 and the inner polygonal opening 12. The cavity 13 has an axial length so that the screwdriver head 14 extending through the cavity 13 only extends to the inner polygonal opening 12 at most, and does not protrude into the inner polygonal opening 12. In a non-preferred embodiment, the socket head 9 can also be slightly shorter so that the working tip 16 slightly extends into the inner polygonal opening 12. However, the inner polygonal opening 12 has an axial length so that although the bit 14 is inserted into the accommodating cavity 13, it can still be used to screw a hexagonal bolt or a hexagonal nut.

[0039] like Figure 7As shown, the screwing tool is equipped with both a socket head 9 and a screwdriver head 14, and can be used to rotate a hexagonal nut or a hexagonal bolt head using an inner polygonal opening 12. The inner polygonal opening 12 can have a hexagonal contour or other internal contour. The axial height of the inner polygonal opening 12 is always large enough to ensure that the surface section of the inner polygonal opening 12 and the surface section of the hexagonal nut or hexagonal bolt head have a sufficiently large contact surface.

[0040] Only by removing the socket head 9 from the output base 2 can the screwing tool be put into the working state, in which the working tip 16 of the screwdriver head 14 inserted into the insertion opening 3 is placed in the screwdriver engagement opening of the bolt or the like. By operating the handle 1, the bolt or nut can be turned in both cases.

[0041] By placing the socket head 9 on the output base 2 , without previously removing the screwdriver head 14 from the insertion opening 3 , the tool can be used again for screwing hexagonal nuts or screws with a hexagonal screw head.

[0042] The slide switch 27 can be configured as follower forks 31, 32 that engage with the latching element 23. The fork openings of the follower forks 31, 32 can engage with the tapered region 33 of the latching element 23 having a circular cross section.

[0043] It can also be provided that the magnet 8 is held axially fixed by means of a spring ring 30 located in a peripheral groove 34. The drive shaft 15 of the screwdriver bit 14 inserted into the insertion opening 3 is fixed in the insertion opening by means of a spring ring 29 located in a peripheral groove 35.

[0044] The tool magazine 18 can be composed of three parts, namely a closing cover 20, a piston 37 and a center piece 19, wherein in the storage position the closing cover closes an opening arranged on the rear end face of the handle 1, the piston is guided on a guide rod 49, and the guide rod extends axially through the cavity 17, and the center piece is arranged between the piston 37 and the closing cover 20.

[0045] The three components of the tool magazine 18 can be plugged together in the axial direction. Here, the latching projections 42' arranged on the free ends of the respective tongue-shaped springs 42 can engage with the latching openings 44 of the other components. The tongue-shaped springs 42, in particular, carry the latching projections 42' that protrude radially outward and, when plugged together, are inserted into the cavities 40 of the other components of the tool magazine 18.

[0046] The piston 37 has a tongue spring 41, which bears against the wall of the cavity 17 under the action of a radially outward spring force. A tongue spring 43 extends into the cavity of the piston 37 and surrounds an opening 43', which can be expanded by the elastic bending of the tongue spring 43. The guide rod 49 has at least one projection 45, 45', which can be overtraveled by the tongue spring 43 when the tool magazine 18 is moved between the storage position and the removal position. The tongue spring 43 and the projection 45, 45' together form a latch, which can secure the tool magazine 18 in the storage position and / or the removal position.

[0047] The end section 49 ′ of the guide rod 49 is inserted into the end opening 51 of the boss 50, which forms a fork that holds the head 21. A press fit serves to axially restrain the guide rod 49 in the end-side opening 51. The axial end of the end section 49 ′ inserted into the end-side opening 51 forms a cavity 52, into which a spring element 53 is inserted, which acts on the latching element 23 into the latching position.

[0048] The closure cap 20 can form the first tool holder 19'. A recess 46' is provided in which a polygonal section of a screwdriver head can be accommodated (see Figure 12 and 18 The recess 46 ′ is closed in the axial direction by a base formed by the closure cover 20 and has a substantially radially extending wall 47 ′, against which the polygonal surface of the polygonal section rests.

[0049] The central part of the tool magazine 18 forms the second tool holder 19, which can have a recess 46 which is identical to the aforementioned recess 46' and has a base 48 (see FIG. Figure 12 and 19 In this structure, the recessed portion 46' and the recessed portion 46 can be respectively inserted with a shorter screwdriver head 55 having a length of 25 mm (see Figure 2 ).exist Figure 19 As can be seen in FIG. 4 , the bottom plate 48 forming the recess 46 has an overall circular shape with mutually opposing arcuate portions 54 .

[0050] However, the closure cap 20 and the piston 37 can also be connected to a central part of another design, which also forms the second tool holder 19, but which only has a fixing effect on the screwdriver bit inserted into the recess 46' (see Figure 20In this configuration, a longer screwdriver bit 55', 50 mm in length, is inserted into recess 46'. The shank of the longer screwdriver bit is retained by retaining tabs 47, which extend primarily radially and are axially flush with walls 47' of recess 46'. Second tool holder 19 differs from the aforementioned second tool holder 19 primarily in that it lacks base plate 48.
