[0030] The left pawl 21 and the right pawl 22 are respectively rotated and locked with the left arm post and the right arm post through the rotary locking assembly 4; the rotary locking assembly 4 includes a first locking part 41 and a second locking part 42 that mesh with each other to form a locking engagement;

[0031] The first locking part 41 of the rotary locking assembly 4 on the left side is fixedly mounted on the left arm post, and the second locking part 42, which locks and engages with the first locking part 41, is fixedly mounted on the corresponding left pawl 21; the first locking part 41 of the rotary locking assembly 4 on the right side is fixedly mounted on the right arm post, and the second locking part 42, which locks and engages with the first locking part 41, is fixedly mounted on the corresponding right pawl 22.

[0032] The first locking part 41 includes a first ring body 411; a toothed ring is provided on the surface of the first ring body 411 facing the second locking part 42, coaxially arranged with the first ring body 411; a plurality of toothed grooves 412 are distributed circumferentially along the axis of the first ring body 411 on the toothed ring, and in this embodiment, each toothed groove 412 is spaced 15° apart, that is, during subsequent adjustments, an angle can be adjusted every 15°; the second locking part 42 includes a second ring body 421; a toothed ring is provided on the surface of the second ring body 421 facing the first locking part 41. A number of protrusions 422 (or multiple protrusions 422 can be evenly distributed around the axis of the second ring 421, as long as the protrusions 422 can engage with the tooth grooves 412 on the toothed ring); the first locking part 41 and the second locking part 42 engage with the tooth grooves 412 of the toothed ring through the protrusions 422 to form a locking fit; the first ring 411 and the second ring 421 are coaxially arranged, and the axis of the first ring 411 and the second ring 421 is the rotation axis of the corresponding left pawl 21 or right pawl 22.

[0033] In this embodiment, the first ring body 411 is located on the inner side of the corresponding fork arm 12 and is in the shape of an annular boss. The groove 412 is a long groove radially distributed along the axis of the first ring body 411, while the protrusion 422 is a semi-cylinder extending radially along the axis of the second ring body 421. The semi-cylinder and the long groove provide greater damping, resulting in a stronger angular locking force on the magnetic ring 3 in the later stages.

[0034] Of course, the annular groove can also be arranged on the inner side of the corresponding fork arm 12, and the annular groove bottom can be used as the first ring body 411. In this way, the second ring body 421 can be embedded in the annular groove and can rotate in the annular groove. When the first ring body 411 is designed as an annular groove, the second ring body 421 can be installed in a hidden manner, and the overall structure is more simple.

[0035] When there is no external force or the external force does not break the engagement locking force of the first locking part 41 and the second locking part 42, the first locking part 41 and the second locking part 42 remain in the locked state. That is, through the hard fit, when the rotating magnetic ring adapter assembly 2 is assembled by rotating, the rotating force breaks the locking force of the first locking part 41 and the second locking part 42, so that the protrusion 422 is separated from the current tooth groove 412 on the tooth ring, and then enters the next tooth groove 412. Since the protrusion 422 and the tooth groove 412 are both injection molded parts, this design can be realized. And this kind of hard locking fit structure is also used in other fields.

[0036] The left clamping jaw 21 and the right clamping jaw 22 are connected together through the connecting sheet 5; the left clamping jaw 21 and the right clamping jaw 22 are both rotatably connected with the left side arm column and the right side arm column through the rotating locking assembly 4; the first locking part 41 of the left rotating locking assembly 4 is fixedly arranged on the left side arm column, and the second locking part 42 is fixedly arranged on the left clamping jaw 21; the first locking part 41 of the right rotating locking assembly 4 is fixedly arranged on the right side arm column, and the second locking part 42 is fixedly arranged on the right clamping jaw 22.

[0038] The connecting sheet 5 is integrally connected with the fixed jaw bodies 2a on the left and right sides.

[0039] Wherein the first claw hook 2a-1 and the second claw hook 2b-1 are clamped on the ring inner wall of the magnetic ring 3, and the shape is matched with the inner wall of the circumference of the magnetic ring 3, that is, the inner side of the hook body of the first claw hook 2a-1 and the second claw hook 2b-1 is a circular arc matched with the inner wall of the circumference of the magnetic ring 3. Of course, other forms that can clamp the magnetic ring 3 are also available.

[0040] Wherein the second ring body 421 can also not be provided, and the protrusions 422 on the second ring body 421 are directly provided on the fixed claw body 2a, as long as the protrusions are engaged with the tooth grooves 412 of the tooth ring on the first ring body 411 after the magnetic ring 3 is installed. This design is equivalent to the design of providing the second ring body 421 in the present embodiment, that is, this scheme should also be included in the protection scope of the utility model.

[0041] Meanwhile, a protection clamping strip 6 is also included; the left clamping jaw 21 and the right clamping jaw 22 are both provided with clamping grooves; the two ends of the protection clamping strip 6 are respectively inserted into the clamping grooves of the left clamping jaw 21 and the right clamping jaw 22; in the present embodiment, the clamping grooves are provided on the fixed claw body 2a; the protection clamping strip 6 is oppositely arranged with the connecting piece 5; the protection clamping strip 6, the connecting piece 5, the left clamping jaw 21 and the right clamping jaw 22 cooperatively form a protection cavity surrounding the circumference direction of the magnetic ring 3. Such arrangement can effectively protect the wire wound on the magnetic ring 3.

[0042] Wherein the clamping groove is a T-shaped groove, and one end of the protection clamping strip 6 clamped into the clamping groove is a reverse T-shaped part matched with the T-shaped groove. When the protection clamping strip 6 is clamped into the clamping groove, the reverse T-shaped part and the T-shaped groove are matched to realize clamping and anti-disengagement installation.

[0043] Meanwhile, the T-shaped groove is a through groove extending along the extension direction of the fixed claw body 2a, which facilitates the clamping of the protection clamping strip 6. Moreover, the protection clamping strip 6 is a spare part, and different widths of the protection clamping strip 6 can be replaced according to needs.

[0044] The connecting main body 11 is provided with an insert 111 matched with a plug-in groove 7 arranged in the support or the inner wall of the shell of the ultrasonic knife controller shell. The insert 111 is provided with elastic teeth 112; the plug-in groove 7 is provided with an embedding groove; when the insert 111 is inserted into the plug-in groove 7, the elastic teeth 112 can be clamped into the embedding groove, thereby forming the assembly and fixation of the connecting main body 11 and the plug-in groove 7. When the elastic teeth 112 and the plug-in groove 7 are adopted, the connection effect of the connecting main body 11 is better and more stable.

[0045] Of course, the insert 111 can also not adopt the elastic teeth 112, and it is also possible to realize fixation only by tight fitting.

[0046] The use mode of the utility model is: first, the line at the place where the magnetic ring needs to be set is wound or passed through the magnetic ring 3, then the magnetic ring 3 is clamped through the left clamping jaw 21 and the right clamping jaw 22, in this process, since the part where the magnetic ring 3 needs to be added in the ultrasonic knife controller is generally the display screen line, signal transmission line, switch power supply incoming line and outgoing line, and the sizes of the magnetic rings at these places are different, therefore, the adjustment of the telescopic jaw body 2b can be used to meet the adaptation.

[0047] When the magnetic ring 3 is installed with the magnetic ring adaptation assembly 2, the connecting main body 11 is inserted and fixedly connected with the embedded groove at the corresponding position (the position of the embedded groove in the ultrasonic knife controller shell has been designed and manufactured in the design).

[0048] Finally, the magnetic ring adaptation assembly 2 is rotated according to the installation space requirement, so that the best installation position is reached.
