[0029] The support frame 102 is provided with a plurality of slide grooves, and the fixed frame 103 can move up and down in the slide grooves and be fastened by bolts or the like, so that the ultrasonic generator 105 can move up and down to adjust the cutting position and height. The fastener 104 includes an extension rod, a U-shaped plate and a fastening ring. The U-shaped plate is fixed to the extension rod by bolts and can move on its surface to adjust the cutting position. The fastening ring is used to fix the ultrasonic generator 105. The cutting knife 106 is made of a material commonly used by people in this field. The working principle of the ultrasonic generator 105 and the like are all prior arts, which can be clearly known to those skilled in the art and will not be elaborated here.

[0030] The adjustment component 200 is arranged between the ultrasonic generator 105 and the cutting knife 106, and includes a fixed tube 201, a connecting member 202, a hinged frame 203, a first adjustment member 204, a second adjustment member 205, a main shaft ring 206, a fastener 207 and a trigger member 208. The fixed tube 201 is fixed to the bottom end of the ultrasonic generator 105, the connecting member 202 slides in the fixed tube 201, the hinged frame 203 is hinged to the bottom of the connecting member 202 and is fixed to the cutting knife 106, the first adjustment member 204 is arranged at the top of the connecting member 202, the second adjustment member 205 is arranged on both sides of the connecting member 202, the main shaft ring 206 slides on the outside of the fixed tube 201, the fasteners 207 are arranged on both sides of the main shaft ring 206, and the trigger member 208 is arranged at the bottom of the fastener 207.

[0031] The connecting piece 202 and the hinged frame 203 are used to install the cutting knife 106 at the bottom end of the ultrasonic generator 105, and ensure that the cutting knife 106 can move up and down and rotate, greatly improving the adjustment range of its angle.

The trigger piece 208 is used to limit the connecting piece 202 and enable it to detach from the fixed tube 201. An anti-slip sleeve is fixed on the surface of the main shaft ring 206, which is convenient for the staff to move it downward.

[0032] Example 2 Reference Figure 2~Figure 6, which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0033] Specifically, the connecting member 202 includes a connecting seat 202a, a slider 202b and a protrusion 202c. The connecting seat 202a slides in the fixed tube 201. Slide grooves S are provided on both sides of the bottom of the fixed tube 201. The slider 202b slides in the slide groove S. The protrusion 202c is fixed on the inner side of the slider 202b. The connecting seat 202a is provided with an annular groove P that cooperates with it. The hinged frame 203 is rotatably connected to the bottom of the connecting seat 202a.

[0034] The connecting seat 202a has a T-shaped cross-section, with a circular top that slides tightly inside the fixed tube 201, and a ring-shaped bottom that is located inside the hinged frame 203. The two are connected by an axial rotation. The slider 202b and the protrusion 202c are used to limit the connecting seat 202a so that it can move up and down with the slider 202b without affecting the rotation of the connecting seat 202a itself.

[0035] The protrusion 202c and the annular groove P are set to be detachably connected, which is convenient for installing the connecting seat 202a in the fixed tube 201. After the installation is completed, the slider 202b will be located inside the main shaft ring 206, so as to ensure that it will not be separated from the slide groove S, thereby improving the disassembly and assembly efficiency of the connecting seat 202a. At the same time, the protrusion 202c and the annular groove P can also be set to a limit mode with a T-shaped cross-section, which can be set by technicians in this field as needed.

[0036] The first adjusting member 204 includes a first ratchet tooth 204a and a second ratchet tooth 204b. The first ratchet tooth 204a is fixed to the top of the connecting seat 202a, and the second ratchet tooth 204b is fixed to the inner top wall of the fixing tube 201 and cooperates with the first ratchet tooth 204a.

[0037] When the connecting seat 202a moves upward, the first ratchet 204a will mesh with the second ratchet 204b, thereby fixing the connecting seat 202a and preventing it from rotating. When the two are disengaged, the connecting seat 202a can catch you, thereby adjusting the position of the cutting knife 106.

[0038] The second adjusting member 205 includes a movable plate 205a and an insertion rod 205b. The movable plate 205a slides on both sides of the connecting seat 202a, and a first inclined surface K1 is provided on the outer side of the top thereof. The insertion rod 205b is fixed on the inner side of the movable plate 205a, and a socket F cooperating with the insertion rod 205b is provided on the outer side of the hinged frame 203.

[0039] The movable plate 205a is arc-shaped and can move left and right. When the connecting seat 202a moves into the fixed tube 201, the inner wall of the bottom of the fixed tube 201 will squeeze the first inclined surface K1 and push the movable plate 205a toward the connecting seat 202a. At this time, the insertion rod 205b will be inserted into the socket F, so that the hinge frame 203 and the connecting seat 202a are relatively fixed to prevent them from shifting during use.

[0040] There are multiple insertion rods 205b, which are distributed in a semicircular shape on the inner side of the movable plate 205a, and there are multiple insertion holes F, which are distributed in a circular shape.

[0041] The second adjusting member 205 further includes a guide rod 205c and a first spring 205d. The guide rod 205c is fixed to both sides of the connecting seat 202a. A guide hole M is opened in the movable plate 205a. The guide rod 205c is located in the guide hole M. The first spring 205d is arranged on the surface of the guide rod 205c.

[0042] Two guide rods 205c are set on each side to guide and limit the movable plate 205a to prevent it from deviating during the left and right movement. The end of the guide rod 205c is fixed with a limit block. The two ends of the first spring 205d are respectively fixed to the limit block and the inner wall of the guide hole M to apply a force to the movable plate 205a away from the connecting seat 202a. An arc groove is opened on the hinged frame 203 to prevent the guide rod 205c from hindering the rotation when it rotates.

[0043] Example 3 Reference Figure 1 to Figure 7 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0044] Specifically, the fastener 207 includes a fixing ring 207a, a fastening plate 207b, a dial plate 207c and an insert block 207d. The fixing ring 207a is fixed to the surface of the ultrasonic generator 105 and is located above the main shaft ring 206. The fastening plate 207b is fixed to both sides of the bottom of the fixing ring 207a. Through holes V are provided on both sides of the main shaft ring 206. The dial plate 207c slides in the through hole V. The insert block 207d is fixed to the inner side of the dial plate 207c. The fastening plate 207b is provided with a fastening hole N that matches it.

[0045] There are two fastening plates 207b, which are symmetrically distributed on both sides of the bottom of the fixing ring 207a. When installing, the bottom of the fastening plate 207b is inserted into the main shaft ring 206 and extends into the through hole V. The dial plate 207c is U-shaped, and an arc-shaped baffle is fixed on the top of the opening of the through hole V to prevent the dial plate 207c from detaching from the through hole V. The plug block 207d is used to fix the fastening plate 207b and the main shaft ring 206. When tightening, first manually squeeze the dial plate 207c toward the through hole V, and then insert the fastening plate 207b into the through hole V until it contacts the dial plate 207c. At this time, the dial plate 207c moves outward to make the plug block 207d inserted into the fastening hole N, and the tightening operation can be completed.

[0046] The fastener 207 further includes a receiving plate 207g, which is fixed to both sides of the inner bottom wall of the main shaft ring 206, and both sides of the top are provided with a second inclined surface K2. The receiving plate 207g is located at the bottom of the slider 202b.

[0047] The receiving plate 207g slides in the slide groove S, and moves up and down with the main shaft ring 206, thereby driving the slider 202b and the connecting seat 202a to move. After the main shaft ring 206 is tightened, the connecting seat 202a is fixed by the receiving plate 207g to prevent it from shaking during use.

[0048] The fastener 207 further includes a second spring 207e and a third spring 207f. Two ends of the second spring 207e are respectively fixed to the fixing ring 207a and the main shaft ring 206. The third spring 207f is fixed to the inner side of the dial plate 207c.

[0049] The second spring 207e applies an upward pulling force to the fixing ring 207a to achieve a certain effect of preventing accidental touch, and it is more convenient to reset after adjusting the angle of the cutting knife 106.

[0050] The trigger member 208 includes a trigger plate 208a and a receiving block 208b. The trigger plate 208a is fixed to the bottom of the dial plate 207c and extends to the bottom of the main shaft ring 206. Grooves L are formed on both sides of the inner wall of the slide slot S, and the receiving block 208b slides in the groove L.

[0051] The trigger plate 208a is L-shaped, and third slopes are provided on both sides of its bottom. The receiving block 208b is L-shaped, and fourth slopes are provided on the tops of opposite sides of the two receiving blocks 208b, and fifth slopes are provided on the bottom.

[0052] When the angle is adjusted normally, the trigger plate 208a moves downward with the main shaft ring 206. At this time, the trigger plate 208a does not contact the receiving block 208b, and when the receiving plate 207g contacts the receiving block 208b, the plane at the bottom contacts the plane at the top of the receiving block 208b. At this time, the receiving plate 207g cannot be detached from the slide groove S.

[0053] When the connecting seat 202a needs to be taken out from the fixed tube 201, the main shaft ring 206 is manually pushed downward, and the dial plate 207c is pushed in the direction of the through hole V, so that the trigger plate 208a is driven to move by the dial plate 207c, thereby squeezing the two receiving blocks 208b through the third inclined surface at the bottom of the trigger plate 208a to move into the groove L until the receiving plate 207g moves to the bottom of the receiving block 208b. At this time, the slider 202b and the connecting seat 202a can move downward with the receiving plate 207g and detach from the fixed tube 201.

[0054] When installation is required, the second inclined surface K2 contacts the fifth inclined surface to push the receiving block 208b into the groove L, and the receiving plate 207g can be slid into the slide groove S at this time.

[0055] The trigger member 208 further includes a fourth spring 208 c fixed in the groove L.

[0056] The two ends of the fourth spring 208c are respectively fixed to the inner wall of the groove L and the receiving block 208b, and the fourth spring 208c applies a force to move the receiving block 208b inward, so as to facilitate its reset.

[0057] During use, when it is necessary to adjust the cutting angle of the cutting knife 106, the staff manually pushes the dial plate 207c in the direction of the through hole V, so that the plug block 207d is disengaged from the fastening hole N. At this time, the main shaft ring 206 can be manually pushed downward, and the connecting seat 202a and the slider 202b follow the receiving plate 207g and the main shaft ring 206 to move downward due to their own gravity, so that the first ratchet 204a is separated from the second ratchet 204b. At this time, the cutting knife 106 and the connecting seat 202a can be rotated to adjust their angles. At the same time, the movable plate 205a follows the connecting seat 202a to move downward, and is pushed outward by the first spring 205d, so that the plug rod 205b is disengaged from the socket F. At this time, the cutting knife 106 and the hinged frame 203 can be manually rotated to adjust the cutting angle of the cutting knife 106 from multiple directions.

[0058] After the adjustment is completed, the main shaft ring 206 is pushed upward. At this time, the connecting seat 202a and the slider 202b are driven upward through the receiving plate 207g, so that the first ratchet 204a is engaged with the second ratchet 204b, and the fixation is completed. At the same time, the inner wall of the bottom of the fixed tube 201 will squeeze the first inclined surface K1 and push the movable plate 205a toward the direction of the connecting seat 202a. At this time, the insertion rod 205b will be inserted into the insertion hole F, so that the hinge frame 203 and the connecting seat 202a are relatively fixed to prevent them from shifting during use. When the fastening plate 207b is inserted into the through hole V until it contacts the dial plate 207c, the dial plate 207c moves outward, so that the plug block 207d is inserted into the fastening hole N, and the fastening operation is completed.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
