Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cutting knife technology, specifically to a handheld ultrasonic cutting knife head fixing device. Background Technology

[0002] Existing ultrasonic cutting tools often lack quick-change blades, or while detachable designs exist (e.g., Chinese Utility Model Patent Publication No. CN104254431A, titled "Ultrasonic Tool"), the chuck with a slit is prone to severe friction and wear during actual ultrasonic applications, necessitating chuck replacement. Manufacturing the slit in the chuck is difficult and costly, placing a financial burden on users. Furthermore, designs where side screws directly hold the blade can shatter the ceramic blade, limiting the material requirements for the blade. Utility Model Content

[0003] The purpose of this invention is to provide a handheld ultrasonic cutter head fixing device to solve at least one of the aforementioned problems in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A handheld ultrasonic cutter head fixing device includes a handheld shell, an ultrasonic transducer, a screw, a blade, and a washer. The front extension rod of the ultrasonic transducer is an amplitude transformer, the end of which extends out of the handheld shell. The amplitude transformer has a central hole and a side threaded hole that communicates with the central hole. The rear end of the blade is a conformal section protruding to one side. Both the conformal section and the washer are inserted into the central hole. The other side of the conformal section is a conformal plane. The washer is a semi-circular washer with its plane fitting against the conformal plane. The screw is threaded into the side threaded hole, and the end of the screw abuts against the washer. The screw is located outside the handheld shell.

[0006] In this technical solution, the rear end of the blade is a conformal section protruding to one side. Both the conformal section and the washer are inserted into the central hole, allowing the blade and washer to be removed from the central hole for easy replacement of the washer. Furthermore, the washer can be made using aluminum profile extrusion, significantly reducing production and usage costs. Since the other side of the conformal section is a conformal plane, and the washer is a semi-circular washer with its flat surface fitting against the conformal plane, the screw is threaded into the side threaded hole, and the end of the screw abuts against the washer. The user inserts the washer and blade into the central hole and secures the blade by pressing the screw against the washer, resulting in a good fastening effect. At the same time, the tail of the blade is thickened and strengthened, allowing for the application of ceramic blades and greatly improving the sharpness and durability of the blade.

[0007] Furthermore, to increase the mating area with the screw, the washer is provided with an abutting surface, and the screw abuts against the abutting surface.

[0008] Furthermore, to facilitate the installation of the ultrasonic transducer, the ultrasonic transducer is provided with a connecting flange, which is fixed inside the handheld housing.

[0009] Furthermore, for easier molding, the gasket is a semi-circular gasket.

[0010] The beneficial effects of this utility model are as follows: In this technical solution, since the rear end of the blade is a conformal section protruding to one side, both the conformal section and the gasket are inserted into the central hole. The blade and the gasket can be removed from the central hole, making it easy to replace the gasket. Moreover, the gasket can be made using aluminum profile extrusion technology, which greatly reduces production and usage costs. Since the other side of the conformal section is a conformal plane, and the gasket is a semi-circular gasket, the gasket plane fits into the conformal plane. The screw is threaded into the side threaded hole, and the end of the screw abuts against the gasket. The user can install the gasket and the blade into the central hole and fix the blade by pressing the gasket with the screw. The fastening effect is good. At the same time, the tail of the blade is thickened and strengthened, which can also be used for ceramic blades, greatly improving the sharpness and durability of the blade.

It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0018] Example 1:

[0019] like Figures 1-5 As shown, this embodiment provides a handheld ultrasonic cutter head fixing device, including a handheld housing 12, an ultrasonic transducer 1, a screw 2, a blade 3, and a washer 4. The front extension rod of the ultrasonic transducer 1 is an amplitude transformer 5, the end of which extends out of the handheld housing 12. The amplitude transformer 5 has a central hole 6 and a side threaded hole 7, which communicates with the central hole 6. The rear end of the blade 3 is a conformal section 8 protruding to one side. Both the conformal section 8 and the washer 4 are inserted into the central hole 6. The other side of the conformal section 8 is a conformal plane 9. The washer 4 is a semi-circular washer 4, with the washer plane 10 of the washer 4 fitting against the conformal plane 9. The screw 2 is threadedly connected to the side threaded hole 7, and the end of the screw 2 abuts against the washer 4. The screw 2 is located outside the handheld housing 12.

[0020] In this technical solution, since the rear end of the blade 3 is a conformal section 8 protruding to one side, and both the conformal section 8 and the gasket 4 are inserted into the central hole 6, the blade 3 and the gasket 4 can be removed from the central hole 6, making it easy to replace the gasket 4. Moreover, the gasket 4 can be made using aluminum profile extrusion technology, which greatly reduces production and usage costs. Since the other side of the conformal section 8 is a conformal plane 9, the gasket 4 is a semi-circular gasket 4, and the gasket plane 10 of the gasket 4 fits against the conformal plane 9. The screw 2 is threaded into the side threaded hole 7, and the end of the screw 2 abuts against the gasket 4. The user inserts the gasket 4 and the conformal section 8 integrally formed on the blade 3 into the central hole 6, and fixes the blade 3 by pressing the gasket 4 with the screw 2. The fastening effect is good. At the same time, the tail of the blade 3 is thickened and strengthened, which can also be used for ceramic blades, greatly improving the sharpness and durability of the blade 3.
