Description of the invention: TECHNICAL FIELD OF THE INVENTION The invention relates to a button hole sewing machine having a button hole cutting device including a lower cutting tool and an upper cutting tool. A releasable clamping device is firmly but replaceably engaged with a cutting tool holder and can be moved downwardly against the lower cutting tool, one cutting tool being a blade and the other cutting tool being a cutting board. 10 BACKGROUND OF THE INVENTION EP 1371779A (corresponding to US 6686798, JP 2004-8804A, CN 1468998A, IN 277 / KOL / 03) teaches a buttonhole sewing machine of this general type, the upper cutting tool of which is adjustable to change the cutting force Drive moved. 15 • Button holes of various lengths and / or shapes are required in practice. Buttonholes of various lengths can be produced with blades of various lengths and cutting boards / holders of various lengths. Because it is easier to access, the upper cutting tool is usually replaced for button hole length or shape changes. However, the space available in the sewing machine is limited, and it is often necessary to remove the sewing clamp elements on both sides of the cutting tool to allow enough space for manual replacement of the upper cutting tool. Removing the sewing clamp element requires the top of the base plate to be opened to expose the drive parts inside the sewing machine. To change the cutting tool, the cutting tool must be grasped with one hand and the clamping device tightening the cutting tool with the other hand to release the cutting tool. This is complicated and time-consuming. There is also the danger that the cutting tool will fall into the open substrate. 5 • 200533800 Risk of cutting tools falling into the substrate can occur when cutting tools that are no longer needed and when inserting another cutting tool. SUMMARY OF THE INVENTION An object of the present invention is to improve this common type of cutting device so that the upper tool can be replaced with one hand [and the danger of the cutting tool falling off during replacement is largely eliminated. … Zero + Knowing, the purpose is achieved by a cutter including a holding device and support, which is used at least temporarily when the clamping device is released, = cutting tool μ in the cutting tool holder. Because when cutting or punching out buttonholes on hard or firm _ even multi-layered sewing material, the cutter and the 2 ::: stress effect, so the inserted cutting tool is firmly ^ tight in the cut red具 架上。 On the bracket. When changing the cutting tool, the worker will use 15 20 to = r'j such as — a screwdriver or — a hexagonal wrench to loosen the clamping thread with one hand and keep it on the cutting tool holder. The temporary fixture of the cutting tool will also be placed on the bracket to make _ 魏 单 手松 loose_ set, after I = the worker removes the cutter with his hand, and after the replacement, use the same to another-use the size The two-cut tool needs to remove the opposite sewing material clamp part from the initial sewing machine. It is not known that according to an advantageous embodiment, the holding system can be a tool carrier forming magnet, preferably a permanent magnet. … Hai cutting Advantageously, the cutting tool is temporarily fixed on the cutting tool holder by including an elastic retainer. In the case where the holding device can ensure the proper situation, the clamping device can advantageously include a clamping jaw that is firmly clamped by the H-shaped piece on the cutting tool, and a compression bomb disposed between the clamping jaw and the threaded piece. Alas. Alternatively, the cutting tool can be fixed on the holder-elastic, and the shape of the spring fits the contour of the cutting tool, so that the cutting tool is flexibly pressed on the cutting tool holder. Brief description of the drawings: The details of the present invention will be clear from the following description of the preferred embodiment in conjunction with the accompanying drawings, of which, Fig. 1 is a button hole _ machine with-button hole cutting device of the sewing machine Figure 2 of the detail is a front view of the buttonhole of the arrow according to Figure 1; Figure 3 is a view of a cutting tool bracket including an upper cutting tool enlarged in comparison with the figure; 15 Figure 4 is based on Figure 3 A view of a cutting tool holder with a cutting tool in the middle arrow 1V; FIG. 5 is a bottom view of the cutting tool holder without the cutting tool according to the arrow V in FIG. 4; FIG. 6 is a drawing according to FIG. 4 20 view of a cutter including a cutting tool with a part of a clamping device exposed; FIG. 7 of… is a view of an improved cutting tool embodiment corresponding to FIGS. 4 and 6; ^ FIG. 8 Yes-view of the sewing material with cuts and seams. t implementation] 200533800 Detailed description of the preferred embodiment Figures 1 and 2 show the basic structure of a buttonhole sewing machine, which includes a bottom substrate 10 in the form of a housing; A protruding column 12; and a cross arm 14 extending from the top of the column 12 and extending parallel to the base plate 105. The base plate 10, the vertical column 12, and the cross arm 14 constitute a C-shaped configuration, which is a general configuration of a sewing machine. The work space of the seamstress is on the left side of the figure. This is also the operation side 15. Below the cross arm 14, two spread-out levers 16 that can move toward and away from each other protrude from the base plate 10. The extension rod 16 is used to operate 10 two similarly openable sewing material clips 18 so as to unfold a sewing material 19 when sewing and cutting a button hole and a seam 17. In addition, Fig. 1 shows a needle 20 which is used to sew a buttonhole seam 17 at a sewing position 23 before or after the buttonhole cut 21 of the sewing material 19 (Fig. 8) is cut. Next, the cutting device of the sewing machine will be described. The button hole cutout 21 is formed by means of a lower cutting tool 22 firmly anchored in the base plate 10 and an upper cutting tool 24 which can be lowered to the lower cutting tool 22. In the example shown in FIG. 丨, the lower cutting tool 22 is a blade, and the upper cutting tool 24 is a cutting plate that cooperates with the blade to form an anvil. The length of the buttonhole cut 21 can be determined by the length of the blade or the length 20 of the cutting plate. In the case where the cutting plate is shorter than the blade, there is no back pressure along the length of the blade where the cutting does not occur. The upper cutting tool 24 is held by a cutting tool bracket 26 fixed to the bottom end of a rod member 28 which is vertically guided by a sliding support 29. The top end of the lever member 28 is connected to a lever 32 via a bracket 30, and the lever 32 is accommodated in the top of the cross arm 14 of the sewing machine to rotate about a shaft 33. The brace allows the movement of the rod 32 to be a pure vertical movement-pneumatically actuated piston-air required for the movement of the rod 28: the element 34 moves at the right end of the rod 32, and the 5 of the element 34 is 35 It is placed inside the substrate 10 to pivot about a shaft 35a through the bottom end of the element. The rod 32 can be used for this purpose. When the element rod 36 is extended from the housing 35, the rod 32 is turned counterclockwise, so that the rod 28 and the cutting tool 24 rise and fall. As shown in FIG. 2, the sewing clips 18 are provided on both sides of the sewing position 23. Each of the 10-seam clamps 18 has a clamp 7 at the bottom end of its pivot lever, and the pole lever 38 is also mounted on the lever 16. These two clamping feet 37 are placed on both sides of the stitching position and are placed on the sewing material 19 so as to be spaced apart by means of the pivot lever%, that is, they are respectively moved to the left and right of Figure 2 in order to unfold the sewing material ... Time to sew. For further details, reference is made to EP 1371770A of 15 above.

As shown in Figs. 3 and 4, the cutting tool holder% includes a guide ㈣ for accommodating the upper ㈣ tool 24, and the material direction ㈣ is adapted to the cross-sectional shape of the head 40 of the cutting tool 24. Therefore, in FIG. 3, the cutter ^ can be pushed from the left side, that is, the operating side 15 of the operator, until the tool abuts on the stopper 42 which is limited to the right side displacement. As shown in Fig. 5 = 6, the guide for the upper cutting tool is composed of a straight S_ " 44 and a left-side wall 46.

In FIG. 6, a protruding cam 64 is provided at the top end of the clamping jaw 48 for clamping the cutting tool 24 in the cutting tool holder 26, and this cam enters a recess of the middle part 50 of the cutting tool holder 26 here. 66. In this way, the clamping jaw 48 is initially positioned. By means of a threaded piece 68 which enters into the middle 15-50 of the cutting tool bracket, the clamping jaw can be retracted against the cutting tool 24 The cutting tool is pressed into a guide 39 comprising two walls 44, 46. In the embodiment described in conjunction with the drawings, the cutting plate can be exchanged if necessary-in this example the upper cutting tool 24- Increase or decrease the length of the button hole again. To this end, a tool 701, in this example a 1620 angle wrench or a screwdriver, must be moved to the threaded piece 68, and the seamstress needs to complete this with his right hand One movement, while holding the cutting tool with his left hand and removing the cutting tool after the jaw 48 has been released. The sewingman uses both hands, but despite the two-handed operation, the cutting tool still exists. Danger of entering the base plate 10 in the form of a housing that is opened when the cutting tool is changed. Especially when the * 200533800 cutting tool is changed frequently, these operations can cause considerable entrapment.

Therefore, the permanent magnet 72 forms a holding device to temporarily hold the cutting tool 24 during the cutting tool 24 replacement. According to the present invention, a permanent magnet 72 is incorporated in the top wall 44 of the guide 39 in the first embodiment. When assembling the cutting tool 24, the cutting judge: 24 can be pushed into the money 44, 46-shaped ㈣ guide ㈣. Then, even if the lost jaw is not fastened, the cutting tool 24 made of the material can be held in the guide 39 by the Yonglai 72. The permanent magnet 72 forms a fixing device, so that the cutting tool view is set at the cutting tool bracket%. Lai Ding must be designed to withstand the weight of the cutting fixture 24 plus a certain safety factor. Another example of the holding device can be seen from FIGS. 4 and 6. In step _, the threaded member 68 is slightly loosened, but remains unscrewed into the thread on the middle portion 50 interacting with it. A compression spring in the recess 76 rests on the outside of the jaw 48 and rests on the head 69 of the threaded member 或 or the collar 78 under the head. As a result, the clamping claw 48 is forced to the clamping position by elastic but reversible action. After loosening the threaded member 68, the cutting tool 24 is still loaded and held in its position by the soft-claw mailer. As shown in Fig. 6, the cutting tool 可 can be grasped by deflecting the clamping jaw 48 to deform the spring 74, and then the cutting tool 24 can be removed from the guide 39. can. Other embodiments of the holding device for holding the cutting tool by the day guard are also counted. Elastic retention clamps can be designed to apply a spring-loaded pressure to the cutting guard to enter the angle formed by the walls 44, 46 of the guide 1§39; 11 • 200533800 • A vacuum mechanism can be designed to suck the cutting tool 24导 器 39。 The guide 39. FIG. 7 shows an alternative to FIG. 6. A leaf spring .80 is provided according to Fig. 7; the leaf spring is angled to fit the contour of the head 40 of the upper cutting tool 24. The leaf spring 80 is mounted to the middle portion 50 of the cutting tool holder 26 5 by means of a threaded member 82. The leaf spring 80 is shaped to be supported from behind the head 40 of the upper cutting tool 24, thereby pressing the cutting tool 24 into an angle formed by the top wall 44 and the side wall 46, and holding the cutting tool flexibly at this. This effect is the same as the flexible preloading of the jaw 48 in FIG. Ban Huang 8 0 must be located in the area not occupied by Yan Claw 4 8. For example, in the side view of FIG. 3-10, the leaf spring can be moved to the right relative to the gripper 48, and in the front view of FIG. 4 ^, the leaf spring can be disposed behind the gripper 48 and hidden there.
