Description

Technical Field

[0001] The present invention belongs to the technical field of horizontal and vertical radial presses for assembling hoses; specifically, the subject matter of the present invention includes a tool-holder clamp, a tool-holder storage, a tool storage and pick-up assembly, and a method for removing a tool set. Background Art

[0002] As is well known, for hose crimping operations, a radial press needs to be equipped with a tool set that is suitable for forming the desired final diameter on the hose to be crimped.

[0003] Obviously, the tool set equipped on the radial press also varies according to the final diameter to be formed.

[0004] Each tool set includes a plurality of blocks (or tools), preferably consisting of a plurality of blocks (or tools), wherein the cross-section of each block (or tool) is in the shape of a part of a circular crown. In addition, each block can be used in conjunction with a corresponding jaw. In this example, the radial press is equipped with a plurality of jaws, and the blocks of the tool set are attached to each of the plurality of jaws, so that pressure is transmitted to the tool set through the plurality of jaws.

[0005] The operations of picking up the tool set from the tool-holder storage and storing the tool set in the tool-holder storage, as well as the steps of installing the tool set on the radial press and removing the tool set from the radial press, are all completed by means of a tool-holder clamp configured to simultaneously carry each block in the tool set.

[0006] In addition, each block is equipped with a pin protruding radially outward, and during the installation of the tool on the press, when the jaws are commanded to close on the tool set, the pin is adapted to be inserted and locked into a corresponding seat formed in the corresponding jaw.

[0007] To accurately install the tool set on the press, it is necessary to ensure the angular alignment of the tools relative to the jaws so that each pin can cooperate with its corresponding seat; in addition, it is also necessary to ensure the axial alignment of the tools so that each tool set can always be located at the center of the press regardless of the length of the tool set. Those skilled in the art know that the length of the tool depends on the diameter of the tube to be crimped.

[0008] Patent EP1610915B1 filed by the same applicant describes a tool support fixture for tool mounting of a radial crimping machine, which is capable of ensuring axial and angular alignment of the tool set during mounting of the tool in the crimping machine.

[0009] A disadvantage is that the tool holder clamp has a complex and bulky mechanical structure due to its long fixed pin around which the sliding pin is mounted. By adjusting the position of the sliding pin along the fixed pin, tool sets of varying lengths can be attached. Furthermore, the sliding pin is at least partially housed within the grip handle.

[0010] To set the position of the sliding pin, the button must be pressed to release the stop cylinder from the transverse groove, the sliding pin must be positioned at the desired length (which is necessary to pick up the tool set) and the button must be released to allow the stop cylinder to engage the transverse groove associated with the desired length.

[0011] Obviously, the operation of adjusting the length of the tool support clamp is extremely complicated.In addition, due to the length of the fixing pin, the clamp is bulky.

[0012] Another example of a tool support fixture according to the prior art is described in EP 3 339 009 A1. Summary of the Invention

[0013] The object of the present invention is to propose a tool-supporting fixture, a tool-supporting storage device, a tool storage and pick-up assembly, and a method for removing a tool set, which are able to at least partially overcome the above-mentioned disadvantages.

[0014] This object is achieved by a tool-supporting fixture according to claim 1 , a tool-supporting storage device according to claim 8 , a tool storage and pick-up assembly according to claim 12 , and a method for removing a tool set according to claim 13 .

[0039] In the following description, elements common to the various embodiments shown in the drawings are denoted by the same reference numerals. Detailed Description

[0040] In the said drawings, reference numeral 1 generally denotes a tool support jig according to the present invention.

[0041] In a general embodiment, the tool support jig 1 is adapted to perform operations of picking up a set of tools 2'; 2'' for a radial press from a tool support storage device 3 and storing the set of tools for the radial press in the tool support storage device.

[0042] The tool-supporting fixture 1 includes a gripping handle 10, a tool-supporting disk 11, and an identification and centering structure 13. The gripping handle 10 extends mainly along the fixture axis P. The tool-supporting disk 11 is located at one end of the gripping handle 10 and is provided with a supporting device 12 adapted to support a set of tools 2'; 2'' in a circular arrangement. The identification and centering structure 13 is slidably engaged outside the gripping handle 10. Specifically, the identification and centering structure 13 remains at least partially engaged with the outer surface of the gripping handle 10 while translating; preferably, the identification and centering structure 13 is coaxial with the gripping handle 10 and slidably surrounds the outer surface of the gripping handle 10.

[0043] The identification and centering structure 13 is translatable along the fixture axis P between a retracted position and a forward position, the retracted position being associated with engaging a first set of tools 2', and the forward position being associated with engaging a second set of tools 2'', the axial length of the second set of tools being different from the axial length of the first set of tools 2'.

[0044] In addition, the identification and centering structure 13 is adapted to form a complementary coupling device 4 with a tool-supporting storage device 3 such that the complementary coupling device 4 is engaged by arranging the identification and centering structure 13 in a position adapted to the length of the set of tools 2'; 2'' to be picked up, so that the tool-supporting fixture 1 can be engaged with the set of tools 2'; 2''. In other words, by arranging the identification and centering structure 13 in the retracted position or the forward position, the tool-supporting fixture 1 can achieve an axial coupling of the complementary coupling device 4.

[0045] The identification and centering structure 13 includes a centering device 41 adapted to form a complementary coupling device 4 with a corresponding centering counterpart device 42 formed on the tool-supporting storage device 3. By arranging the identification and centering structure 13 in a position adapted to the length of the set of tools 2'; 2'' to be picked up, the centering device 41 is configured to achieve engagement with the corresponding centering counterpart device 42, so that the tool-supporting fixture 1 can be engaged with the set of tools 2'; 2''.

[0046] For the purposes of this discussion and unless otherwise specified, the term "axial" and its corresponding derivatives shall be understood to refer to a direction parallel or coincident with the fixture axis P.

[0047] Preferably, the identification and centering structure 13 can be positioned only in the retracted position or the forward position. Alternatively, there can be a plurality of intermediate positions between the retracted position and the forward position.

[0048] Preferably, the support device 12 includes a plurality of support pins 121 and a plurality of support magnets 122. The plurality of support pins 121 are arranged along a circular ring, wherein each of the plurality of support pins 121 is adapted to engage with a corresponding pin seat 221 formed on each tool in the tool set. Furthermore, the plurality of support magnets 122 are also arranged along a circular ring, wherein each of the plurality of magnets 122 is adapted to or attached to a corresponding block (or tool) in the tool set. The engagement of the plurality of support pins 121 and the plurality of support magnets 122 with the tool set 2'; 2'' enables the tool support tray 11 to stably support the tool set 2'; 2'' during the operation of picking up the tool set 2'; 2'' from / storing the tool set in the tool support storage device 3.

[0049] Preferably, the gripping handle 10 includes a centering pin 101 positioned at the end where the gripping handle 10 is integrally joined to the tool support disk 11. In this example, the tool support disk 11 is coaxially coupled to the gripping handle 10 by the centering pin 101 and is integrally formed.

[0050] In one embodiment, the determining and centering structure 13 comprises an annular nut 5 that slides on the gripping handle 10. Moving the annular nut 5 on the gripping handle 10 causes the determining and centering structure 13 to translate axially; thus, the determining and centering structure 13 can be arranged in a retracted position or an advanced position.

[0051] Preferably, the ring nut 5 is movable along the gripping handle 10 thanks to a guide groove formed in its outer surface; this guide groove couples the rotation of the ring nut 5 to the axial translation of the determining and centering structure 13 .

[0052] According to one embodiment, the determining and centering structure 13 further comprises a centering frame 130 projecting beyond the radial extent of the tool-supporting disc 11. Specifically, the centering frame 130 is adapted to bear against the front surface of the radial crimping machine in order to ensure angular alignment between the tool set 2'; 2" and the corresponding jaws equipped with the radial crimping machine.

[0053] Preferably, centering frame 130 includes a pair of mushroom pegs 131 at the top and a pair of pins 132 at the bottom. The engagement of tool-supported fixture 1 with the front surface of the radial crimping machine, and in particular the engagement of mushroom pegs 131 and pins 132 with this front surface, ensures angular alignment of tool set 2 ′, 2 ″ relative to the jaws. The terms "upper," "lower," and their derivatives are intended to refer to tool-supported fixture 1 in its operative state.

[0054] According to one embodiment, the complementary coupling device 4 includes a centering device 41 formed on the defining and centering structure 13. In other words, the defining and centering structure 13 includes the centering device 41.

[0055] In addition, the complementary coupling device 4 is also adapted to include a corresponding centering counterpart device 42 formed on the tool support storage device 3.

[0056] The centering device 41 and the centering counterpart device 42 can be engaged with each other such that the tool support fixture 1 engages with the tool sets 2'; 2'' and allows the tool sets 2'; 2'' to be axially removed from the tool support storage device 3. In other words, the centering device 41 can be engaged to the centering counterpart device 42; in this way, the tool support fixture 1 is adapted to engage with the tool sets 2'; 2'' to axially remove the tool sets 2'; 2'' from the tool support storage device 3.

[0057] According to one embodiment depicted in the accompanying drawings Figures 1 to 1e The centering device 41 includes a centering bolt 410 provided with a smaller portion 411 and axially protruding from the defining and centering structure 13. When the defining and centering structure 13 is in a position adapted to the tool set 2'; 2'' to be picked up, the smaller portion 411 can engage with the centering counterpart device 42.

[0058] The tool support fixture 1 can be rotated to disengage the tool sets 2'; 2'' from the tool support storage device 3, and the smaller portion 411 is configured to remain engaged with the centering counterpart device 42 during the rotation of the tool support fixture 1.

[0059] As will be further discussed below, after the tool support fixture 1 is arranged in a position adapted to the tool set 2'; 2'' to be picked up, the engagement of the centering device 41 with the corresponding centering counterpart device 42 provided on the tool support storage device 3 can be achieved. Therefore, after the tool support disk 11 is engaged with the tool sets 2'; 2'' and the engagement of the complementary coupling device 4 is also achieved, the tool support fixture 1 is rotated and pulled to remove the tool sets 2'; 2'' from the tool support storage device 3. Therefore, the centering device 41 can be rotated relative to the corresponding centering counterpart device 42, while the centering counterpart device remains fixed. When the tool sets 2'; 2'' are removed from the tool support storage device 3, the tool sets are supported by the tool support fixture 1 for continued installation of the tools onto the radial press.

[0060] According to one embodiment depicted in the accompanying drawings Figures 2 to 2dIn the illustrated embodiment, the centering device 41 includes a centering flange 412 on which a pair of holes 413'; 413'' are formed, and the pair of holes are interconnected by a groove 414, wherein the width of the groove is smaller than the diameter of each of the pair of holes 413'; 413''. Preferably, the groove 414 is through.

[0061] When the centering structure 13 is in a position adapted to the tool sets 2'; 2'' to be picked up and is determined and centered, the centering device 41 can engage with the centering corresponding device 42.

[0062] The tool support jig 1 can be rotated to disengage the tool sets 2'; 2'' from the tool support storage device 3, and the centering device 41 is configured to be adapted to engage with the corresponding centering corresponding device 42 during the rotation of the tool support jig 1.

[0063] Preferably, only when the engagement between the tool support disk 11 and the tool sets 2'; 2'' is achieved, is it possible to also achieve the engagement between the complementary coupling devices 4, so that the tool support jig 1 can be rotated and pulled, thereby allowing the tool sets 2'; 2'' to be removed from the tool support storage device 3. According to an exemplary variant, the engagement between the tool support disk 11 and the tool sets 2'; 2'' and the engagement between the complementary coupling devices 4 are carried out simultaneously.

[0064] According to another exemplary variant, only after the engagement between the complementary coupling devices 4 is achieved, is it possible to also achieve the engagement between the tool support disk 11 and the tool sets 2'.

[0065] According to one embodiment, the centering device 41 and the centering frame 130 are made as one piece, or the centering device is fixed to and integrated with the centering frame 130.

[0066] Preferably, in the embodiment where the centering device 41 is fixed to the centering frame 130, such attachment is achieved by bolt connection, welding, adhesion or by form coupling and / or force coupling.

[0067] In a general embodiment according to the present invention, there is also provided a tool support storage device 3 for tool installation of a radial press, which includes a support frame 6, at least one tool set 2'; 2'' and a plurality of tool support housings 7.

[0068] For example, the support frame 6 includes a bottom wall, and a plurality of tool support housings 7 are fixed to the bottom wall.

[0069] The tool set 2'; 2'' comprises a plurality of blocks 20'; 20'', the cross section of which is in the shape of a portion of a circular ring, wherein each block (or tool) of the plurality of blocks 20'; 20'' is provided with a pin 21 protruding radially outwards. Furthermore, the tool set 2'; 2'' can be engaged with the tool-supporting fixture 1.

[0070] Preferably, the first tool set 2' has a first axial length L1 and the second tool set 2' has a second axial length L2, wherein the first axial length L1 is smaller than the second axial length L2 (L1 <L2)。

[0071] A plurality of tool support housings 7 are fixed to the support frame 6 and each of the plurality of tool support housings 7 is configured to accommodate a tool set 2 ′; 2 ″. Preferably, the first tool set 2 ′ or the second tool set 2 ″ can be accommodated in each tool support housing.

[0072] Each tool-supporting housing comprises a generally cylindrical housing body 70 which internally defines a compartment 71 for accommodating a tool set 2 ′; 2 ″.

[0073] In the housing body, longitudinal slits 72 are formed, which are open at the front (e.g., on the side opposite to and away from the support frame 6) and terminate at the rear (e.g., on the side close to the support frame 6) in slots 73 inclined 90° relative to the longitudinal slits 72. Each of the longitudinal slits 72 and the corresponding slot is configured to slidably accommodate the pin 21.

[0074] The tool support storage device 3 is adapted to form a complementary coupling device 4 with the tool support fixture 1; in particular, the tool support storage device 3 forms a complementary coupling device 4 with the determining and centering structure 13, so that the complementary coupling device 4 can only be brought into engagement, and thus the tool support fixture 1 can be brought into engagement with the tool set 2'; 2'', by arranging the determining and centering structure 13 in a position adapted to the length of the tool set 2'; 2'' to be picked up. In other words, the tool support storage device 3 can form a complementary coupling device 4 with the determining and centering structure 13 of the tool support fixture 1.

[0075] The engagement of the complementary coupling means 4 is carried out outside the housing body 70 , ie outside the compartment 71 .

[0076] The tool-supported storage device 3 includes a centering corresponding device 42 which is adapted to form such a complementary coupling device 4 with a corresponding centering device 41 formed on a defined and centered structure 13 of the tool-supported fixture 1. By arranging the defined and centered structure 13 in a position adapted to the length of the tool set 2'; 2'' to be picked up, the centering corresponding device 42 is configured to engage with the corresponding centering device 41, so that the tool-supported fixture 1 can engage with the tool set 2'; 2''. Such a centering corresponding device 42 is located outside the housing body 70.

[0077] Preferably, each housing body 70 extends along a housing axis S which substantially coincides with the fixture axis P when the tool set 2'; 2'' is received in the compartment 71 (i.e., located inside the tool-supported housing 7).

[0078] According to one embodiment, the complementary coupling device 4 includes a centering corresponding device 42 formed on the tool-supported storage device 3. In other words, the tool-supported storage device 3 includes a centering corresponding device 42.

[0079] In addition, the complementary coupling device 4 is further adapted to include a corresponding centering device 41 formed on the defined and centered structure 13.

[0080] These centering devices 41 and centering corresponding devices 42 can engage with each other, so that the tool-supported fixture 1 can engage with the tool set 2'; 2'' and axially remove the tool set 2'; 2'' from the tool-supported storage device 3. In other words, the centering corresponding device 42 can engage with the centering device 41, so that the tool set 2'; 2'' is adapted to engage with the tool-supported fixture 1 and then the tool set is axially removed from the tool-supported storage device 3.

[0081] The centering corresponding device 42 is fixed and connected to the support frame 6 and / or the housing body 70. Preferably, the centering corresponding device 42 is rigidly connected to the support frame 6 and forms an integral body ( Figure 3a 、 Figure 4a 、 Figure 5a 、 Figure 6a ).

[0082] According to one embodiment, the centering corresponding device 42 is adapted to cooperate with a corresponding centering device 41 of the tool-supported fixture 1.

[0083] According to the appended drawings Figures 3 to 3a and Figures 4 to 4a. The centering device 42 includes a coupling flange 422 having a pair of coupling holes 423', 423" formed therein. The pair of coupling holes are connected to each other by a guide portion 424. The width of the guide portion is smaller than the diameter of each of the pair of coupling holes 423', 423". Preferably, the guide portion 424 is through-hole.

[0084] When the centering structure 13 is determined and is in a position adapted to the tool set 2 ′; 2 ″ to be picked up, the counter-centering device 42 can engage with the centering bolt 410 .

[0085] Furthermore, the centering counter-device 42 is configured to engage with the centering pin 410 when the tool support fixture 1 is rotated to release the tool set 2 ′; 2 ″ from the tool support storage device 3 .

[0086] According to the attached drawings Figures 5 to 5 a and Figures 6 to 6 In the embodiment depicted in FIG. a , the counter-centering means 42 are adapted to cooperate with the corresponding centering means 41 of the tool support fixture 1 .

[0087] The centering counter-device 42 comprises a coupling pin 420 provided with a smaller coupling portion 421. The axial length of the coupling pin 420 is longer than the axial length of the tool-supporting housing. When the centering structure 13 is positioned to accommodate the tool set 2 ′; 2 ″ to be picked up, the smaller coupling portion 421 is adapted to engage with the corresponding centering device 41.

[0088] The smaller coupling portion 421 is configured to remain engaged with the centering device 41 during rotation of the tool support fixture 1 to disengage the tool set 2 ′; 2 ″ from the tool support storage device 3 .

[0089] Preferably, the coupling pin 420 protrudes axially from the bottom wall of the support frame 6 .

[0090] In a general embodiment of the present invention, a tool storage and picking assembly 8 is also provided, which includes a tool support fixture 1 and a tool support storage device 3. Therefore, the tool support fixture 1 and the tool support storage device 3 are associated with each other so that they are configured in a "plug and socket" manner.

[0091] Specifically, in the accompanying drawings Figures 3 to 3a 、 Figures 4 to 4 a. Figures 5 to 5 a and Figures 6 to 6In the embodiment shown in Figure a, the tool set 2'; 2'' is housed in the corresponding tool support housing 7, and the pin 21 of each block (or tool) engages with the corresponding slot 73. After the tool support disc 11 is engaged with the tool set 2'; 2'', the engagement between the complementary coupling means 4 can also be achieved by translating the determining and centering structure 13. Therefore, after the engagement of the tool support disc 11 with the tool set 2'; 2'' is achieved and the mutual engagement between the centering means 41 and the centering counter means 42 is also achieved, the tool set 2'; 2'' can be removed from the tool support housing 7 by rotating the tool support fixture 1. The rotation of the tool support fixture 1 involves rotating the centering means 41 relative to the centering counter means 42 and allowing the pin 21 of each block to slide along the corresponding slot 73 so as to align with the corresponding longitudinal slit. Aligning the pin 21 along the longitudinal slit allows the tool support clamp to be pulled out, thereby releasing the engagement between the centering means 41 and the counter-centering means 42 and removing the tool set 2 ′; 2 ″ axially from the tool support storage device 3 .

[0092] According to the accompanying drawings Figures 3 to 3a as well as Figures 4 to 4 In the embodiment of FIG. 1 , the smaller portion 411 of the centering pin 410 engages with the first coupling hole 423 ′. During rotation of the tool-supporting fixture 1 , the smaller portion 411 slides along the guide 424 and reaches the second coupling hole 423 ″. This allows the tool set 2 ′; 2 ″ to be removed from the tool-supporting storage device 3 .

[0093] According to the accompanying drawings Figures 5 to 5 In the embodiment of FIG. 1 , the smaller coupling portion 421 of the coupling pin 420 engages with the first hole 413 ′. When the tool support fixture 1 is rotated, the smaller coupling portion 421 slides along the groove 414 and reaches the second hole 413 ″. This allows the tool set 2 ′ to be removed from the tool support storage device 3 .

[0094] exist Figure 6a In the embodiment shown, since the centering structure 13 is in the retracted position, the smaller coupling portion 421 of the coupling pin 420 is not engaged with the first hole 413' and must be moved to the advanced position to engage with the complementary coupling device 4 and remove the tool set 2'.

[0095] Preferably, in order to equip a horizontal radial press, the tool support jig 1 must also ensure accurate axial alignment and radial alignment. In fact, since the jaws are displaced along the horizontal axis of the press, it is also necessary to ensure that the pins 21 of each block are axially aligned with respect to the seats formed in the corresponding jaws. "Axial alignment" means that each pin 21 and its corresponding seat must reach the same height along the horizontal axis of the press, taking into account the movement of the pin seats along this horizontal axis until the jaws reach the final position of full connection with the tool sets 2'; 2''. Therefore, the distance X between the centering frame 130 and the tool support disk 11 must be consistent with the distance between its center and the front surface against which the jaws of the press rest. By adjusting the translation of the fixed and centering structure 13 according to the axial length of the tool set to be picked up, the tool set can be removed from the storage device only by the engagement between the centering device 41 and the centering corresponding device 42. The engagement of the complementary connection device 4 ensures that the space between the centering frame 130 and the tool support disk 11 is equal to the distance X. In this way, regardless of the length of the tool pins, axial centering of the tool pins with respect to the seats in the jaws can always be achieved.

[0096] According to the present invention, a method for removing the tool sets 2'; 2'' from the tool support storage device 3 is also proposed. The method includes:

[0097] - Providing a tool storage and pickup assembly 8;

[0098] - Holding the tool support jig 1 and moving the tool support jig close to the tool support storage device 3 to pick up the tool sets 2'; 2'' having the required axial length, so as to perform a crimping operation;

[0099] - Arranging the fixed and centering structure 13 in the retracted position to pick up the first tool set 2', or arranging the fixed and centering structure in the advanced position to pick up the second tool set 2'';

[0100] - Engaging the tool support disk 11 with the tool sets 2'; 2'' to be picked up;

[0101] - Engaging the centering device 41 of the tool support jig 1 with the corresponding centering corresponding device 42 of the tool support storage device 3;

[0102] - Rotating the tool support jig so that the pins 21 of each block move along the slots 73 until they are aligned with the corresponding longitudinal slits;

[0103] - Pulling the tool support jig 1 so that the movement of each pin 21 along the longitudinal slit allows the tool sets 2'; 2'' to be removed from the tool support housing.

[0104] According to an embodiment of the method, the following steps are further included:

[0105] - A joint is formed between the centering device 41 of the tool - supported fixture 1 and the corresponding centering counterpart device 42 of the tool - supported storage device 3 by inserting the centering bolt 410 into the first coupling hole 423' of a pair of coupling holes 423', 423''.

[0106] - Rotate the tool - supported fixture; in this way, the smaller part 411 (whose cross - section is smaller than the cross - section of the centering bolt 410) slides along the guiding portion 424 and allows the centering bolt 410 to reach the second coupling hole 423'' of the pair of coupling holes 423', 423''. The angular distance that the tool - supported fixture 1 moves the centering bolt 410 from the first coupling hole 423' to the second coupling hole 423'' is consistent with the angular distance that the pin 21 of each block slides along the groove 73 and axially aligns with the corresponding longitudinal slit.

[0107] According to an embodiment of the method, the following steps are further included:

[0108] - A joint is formed between the centering device 41 of the tool - supported fixture 1 and the corresponding centering counterpart device 42 of the tool - supported storage device 3 by inserting the coupling bolt 420 into the first hole 413' of a pair of holes 413', 413''.

[0109] - Rotate the tool - supported fixture 1; in this way, the smaller coupling part 421 (whose cross - section is smaller than the cross - section of the coupling bolt 420) slides along the groove 414 and allows the coupling bolt 420 to reach the second hole 413'' of the pair of holes 413', 413''. The angular distance that the tool - supported fixture 1 moves the coupling bolt 420 from the first hole 413' to the second hole 413'' is consistent with the angular distance that the pin 21 of each block slides along the groove 73 and axially aligns with the corresponding longitudinal slit.

[0110] Innovatively, the tool - supported fixture, the tool - supported storage device, the tool storage and pickup assembly, and the tool set removal method achieve their intended purposes.

[0111] Advantageously, the tool - supported fixture saves space axially because its axial range is generally between the tool - supported disk and the end of the gripping handle opposite to the tool - supported disk.

[0112] Advantageously, the tool - supported fixture saves space radially, or its radial range is comparable to the radial extension of the tool - supported fixture according to the prior art, because the radial range of the tool - supported fixture is determined by the size of the centering frame.

[0113] According to an advantageous aspect, since the positioning and centering structure slides on the outer surface of the gripping handle and the centering means is formed outside the gripping handle, the tool-supporting fixture is structurally easier to manufacture.

[0114] According to another advantageous aspect, since the positioning and centering structure is located outside the gripping handle, the operator can easily adjust its translation, so the tool-supporting fixture is mechanically easier to use. In addition, since the centering means is formed outside the gripping handle, the operator can also easily operate the centering means.

[0115] Advantageously, since the engagement of the complementary coupling means is achieved outside the housing body and only the tool set can be accommodated in the compartment inside the housing body, the functionality of the tool-supporting storage device is extremely powerful.

[0116] According to an advantageous aspect, the tool receiving and picking-up assembly is practical because the tool set can be removed from the tool-supporting storage device only after an engagement is formed between the tool-supporting tray and the tool set and also an inter-engagement is formed between the centering means and the centering corresponding means. However, the connection between the centering means and the centering corresponding means is formed outside both the gripping handle of the tool-supporting fixture and the tool-supporting housing.

[0117] For embodiments of the tool-supporting fixture, the tool-supporting storage device, the tool receiving and picking-up assembly, and the method for removing the tool set according to the present invention, in order to meet accidental requirements, those skilled in the art can modify, adjust, and substitute elements with functionally equivalent elements without departing from the protection scope of the appended claims. Each feature described as belonging to a possible embodiment can be obtained independently of the other described embodiments.
