When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0022] In medical plastic surgery, the blade body is driven by a medical plastic surgery mobile phone to perform corresponding movements to perform plastic surgery operations such as sawing or cutting off human bone tissue. In the prior art, the connection between the blade body and the medical plastic surgery mobile phone is not strong enough, so that the blade body may deviate and vibrate during the operation, which may lead to medical accidents in serious cases.

[0023] In order to solve the above technical problem, the present invention proposes a blade installation structure.

[0024] See also Figure 1-4 In one embodiment of the present invention, the blade mounting structure is applied to a medical plastic surgery mobile phone 100; the blade mounting structure is used to mount a blade body 200 to the medical plastic surgery mobile phone 100, wherein the blade body 200 includes a blade portion 210 and a handle portion 220 of a cylindrical structure; Specifically, the blade mounting structure includes: The shaft tube 300 is installed, and a mounting cavity 310 is provided inside the shaft tube 300. The mounting cavity 310 is used to sleeve the handle portion 220, and the inner side wall of the mounting cavity 310 and the outer side surface of the handle portion 220 are mutually attached to limit the radial movement of the handle portion 220; Among them, a limit piece 230 is provided at the end of the handle part 220 away from the blade part 210, and a notch part 240 is provided at the connection between the limit piece 230 and the handle part 220; the blade mounting structure also includes a first positioning block 320 and a second positioning block 330; the first positioning block 320 is fixedly arranged in the mounting cavity 310, and the first positioning block 320 is used to be embedded in the notch part 240 to limit the axial movement of the handle part 220; the second positioning block 330 is slidably connected to the mounting cavity 310, and the second positioning block 330 is used to abut the side of the limit piece 230 to limit the circumferential movement of the handle part 220.

[0025] The technical solution of the present invention is to set the handle part 220 into a cylindrical structure. When the handle part 220 is sleeved in the installation cavity 310, the inner side wall of the installation cavity 310 and the outer side surface of the handle part 220 are in contact with each other, so as to achieve the purpose of limiting the radial movement of the handle part 220; at the same time, a first positioning block 320 and a second positioning block 330 are arranged inside the installation cavity 310. After the handle part 220 is installed in the installation cavity 310, on the one hand, the first positioning block 320 is embedded in the notch part 240. At this time, the two sides of the first positioning block 320 are respectively abutted against the ends of the handle part 220 and the opposite side of the limiting member 230, so that the blade body 200 cannot move axially under the restriction of the first positioning block 320; on the other hand, the second positioning block 330 slides to abut against the side of the limiting member 230. Due to the obstruction of the second positioning block 330, the limiting member 230 cannot rotate along the axis of the handle part 220, that is, the circumferential movement of the handle part 220 is limited. In summary, the radial movement, axial movement and circumferential movement of the handle portion 220 are all restricted, so that the blade body 200 cannot be displaced relative to the mounting shaft tube 300, thereby improving the connection firmness between the blade body 200 and the medical plastic surgery mobile phone 100 to ensure that the blade body 200 does not deviate from vibration during the operation.

[0026] Further, there is a preset gap 380 between the first positioning block 320 and the mounting cavity 310, and the cross-sectional area of ​​the preset gap 380 is larger than the cross-sectional area of ​​the stopper 230, and the cross-sectional area of ​​the preset gap 380 is smaller than the cross-sectional area of ​​the handle 220. In this way, the preset gap 380 can allow the stopper 230 to pass through, and the handle 220 cannot pass through the preset gap 380. After the stopper 230 passes through the preset gap 380, the blade body 200 is rotated by a certain angle, so that the notch 240 of the stopper 230 and the first positioning block 320 are interlocked and connected with each other, thereby achieving the purpose of limiting the axial movement of the handle 220 by the first positioning block 320.

[0027] As a preferred solution of the above embodiment, refer to the attached Figure 1-4The mounting structure also includes a sliding ring 340 slidably sleeved on the mounting shaft tube 300, a sliding groove 350 is opened on the side of the mounting shaft tube 300, and the groove direction of the sliding groove 350 is arranged along the axial direction of the mounting shaft tube 300; a connecting pin 360 is slidably connected in the sliding groove 350, and the sliding ring 340 is fixedly connected to the second positioning block 330 through the connecting pin 360; a first spring 370 is arranged in the mounting cavity 310, and the first spring 370 is arranged between the second positioning block 330 and the inner bottom of the mounting cavity 310. In this way, when the handle 220 is inserted into the installation cavity 310, its limiting member 230 passes through the preset gap 380 and then abuts against the end of the second positioning block 330; as the handle 220 continues to be inserted, the limiting member 230 drives the second positioning block 330 to move toward the inner bottom direction of the installation cavity 310, during which the second positioning block 330 compresses the first spring 370; when the blade body 200 rotates a certain angle so that the notch 240 of the limiting member 230 and the first positioning block 320 are interlocked, the limiting member 230 is rotated to the point where it does not abut against the end of the second positioning block 330, and the second positioning block 330 lacks the limiting member 2 30, thereby driving the second positioning block 330 to move toward the handle portion 220 under the elastic force of the second spring, so that the side of the second positioning block 330 and the limiting member 230 abut against each other; since the second positioning block 330 is connected to the sliding ring 340 through the connecting pin 360, and the connecting pin 360 is restricted to slide in the sliding groove 350 of the mounting shaft tube 300, the movement trajectory of the second positioning block 330 can only move along the axial direction of the mounting shaft tube 300, and cannot perform circumferential movement; thereby, the limiting member 230 abutted by the second positioning block 330 cannot perform circumferential movement, so as to achieve the purpose of limiting the circumferential movement of the handle portion 220.

[0028] Furthermore, two connecting pins 360 are symmetrically arranged on opposite sides of the second positioning block 330, and the sliding grooves 350 correspond one to one with the connecting pins 360. With such an arrangement, when the sliding ring 340 slides the second positioning block 330 through the connecting pins 360, the opposite sides of the second positioning block 330 are balanced in force, which is conducive to improving the stability of the second positioning block 330 when sliding.

[0029] As an alternative to the connecting pin, in another embodiment, the blade mounting structure can be designed to include a connecting bolt and a connecting nut, and the connecting bolt passes through the sliding groove, the sliding ring and the second positioning block in sequence and then is threadedly connected with the connecting nut. In this way, through the combination of the connecting bolt and the connecting nut, the sliding ring and the second positioning block are combined to form a whole, and can slide along the sliding groove. It can be understood that a through hole for the connecting bolt to pass through is provided on the sliding ring and the second positioning block to ensure that the connecting bolt can smoothly pass through the moving ring and the second positioning block.

[0030] As a preferred solution of the above embodiment, refer to the attached Figure 1-4 The mounting structure further includes a push sleeve assembly 400, which is used for the operator to slide the sliding ring 340; in this arrangement, considering that when replacing the blade body 200, it is necessary to first release the restriction of the second positioning block 330 on the limiter 230, so that the handle 220 can rotate circumferentially until its limiter 230 is aligned with the preset gap 380, so that the limiter 230 can pass through the preset gap 380 to pull the handle 220 out of the mounting shaft tube 300; therefore, the operator needs to slide the sliding ring 340 to move the second positioning member toward the inner bottom direction of the mounting cavity 310, thereby releasing the restriction of the second positioning block 330 on the limiter 230. In order to facilitate the operator to slide the sliding ring 340, the present embodiment is provided with a push sleeve assembly 400 on the mounting structure.

[0031] Specifically, the push sleeve assembly 400 includes a guide sleeve 410 slidably mounted on the mounting shaft tube 300, and a push sleeve group 420 slidably mounted on the first end of the guide sleeve 410, at least a portion of the push sleeve group 420 is exposed to the outside of the medical plastic surgery mobile phone 100, and the guide sleeve 410 is fixedly connected to the medical plastic surgery mobile phone 100; a guide groove 411 is provided on the side of the guide sleeve 410, and the groove direction of the guide groove 411 is arranged along the axial direction of the mounting shaft tube 300; a push pin 430 is slidably connected in the guide groove 411, one end of the push pin 430 is fixedly connected to the push sleeve group 420, and the other end of the push pin 430 abuts against the end of the sliding ring 340 away from the second spring. In this way, at least part of the push sleeve 420 in this embodiment is exposed outside the handle body, and the operator slides the push sleeve 420 through the exposed area to move it toward the inner bottom of the installation cavity 310; since the push sleeve 420 is connected with the push pin 430, during the movement of the push sleeve 420, the push pin 430 pushes the sliding ring 340 toward the inner bottom of the installation cavity 310, thereby achieving the purpose of releasing the second positioning block 330 from the restriction on the limiter 230. At the same time, since the push pin 430 is restricted to slide in the guide groove 411 of the guide sleeve 410, and the groove direction of the guide groove 411 is set along the axial direction of the installation shaft tube 300, the push sleeve 420 can only move along the axial direction of the installation shaft tube 300 when pushed by the operator, which is conducive to improving the guiding performance of the push sleeve 420 when moving.

[0032] Furthermore, a protrusion 412 is provided at the second end of the guide sleeve 410, and a second spring 440 is sleeved on the guide sleeve 410, and the second spring 440 is provided between the push sleeve 420 and the protrusion 412. In this way, when the push sleeve 420 pushes the sliding ring 340, the push sleeve 420 compresses the second spring 440; when the blade body 200 and the medical plastic surgery mobile phone 100 are separated from each other, the operator releases the force applied to the push sleeve 420, and the push sleeve 420 is reset under the elastic force of the second spring 440.

[0033] Furthermore, two push pins 430 are symmetrically arranged on opposite sides of the push sleeve 420, and the sliding grooves 350 correspond to the connecting pins 360. With such an arrangement, when the push sleeve 420 pushes the sliding ring 340 through the push pins 430, the forces on both sides of the sliding ring 340 are balanced, which is conducive to improving the stability of the sliding ring 340 when sliding.

[0034] Furthermore, the exposed area of ​​the push sleeve 420 is provided with anti-skid lines 421. In this way, the anti-skid lines 421 are used to increase the friction between the operator and the push sleeve 420, so that the operator can push the push sleeve 420 easily.

[0035] The following is a detailed description of the disassembly and assembly process of the blade body 200 and the handle body in combination with the above embodiments: When installing the blade body 200: Step 1: Refer to the attached Figure 5 , insert the handle portion 220 of the blade body 200 into the mounting cavity 310 of the mounting shaft tube 300 located inside the medical plastic surgery mobile phone 100, because the inner side surface of the mounting cavity 310 and the outer side surface of the handle portion 220 fit each other to limit the radial movement of the handle portion 220; at this time, the stopper 230 of the handle portion 220 and the preset gap 380 between the first positioning block 320 and the mounting cavity 310 are aligned with each other; Step 2: Refer to the attached Figure 6 As the handle 220 is further inserted, the limiting member 230 passes through the preset gap 380 until the first positioning block 320 and the end of the handle 220 abut against each other; during this period, the limiting member 230 abuts against the end of the second positioning block 330 after passing through the preset gap 380, and as the handle 220 is further inserted, the limiting member 230 drives the second positioning block 330 to move toward the inner bottom of the installation cavity 310, during which the second positioning block 330 compresses the first spring 370; Step 3: Refer to the attached Figure 7-8, the blade body 200 is rotated by a certain angle, on the one hand, the notch portion 240 of the limiting member 230 is engaged with the first positioning block 320 to limit the axial movement of the handle portion 220; on the other hand, the limiting member 230 is rotated until it is no longer in contact with the end of the second positioning block 330, and the second positioning block 330, due to the lack of contact with the limiting member 230, moves toward the handle portion 220 under the elastic force of the first spring 370, so that the side of the second positioning block 330 is in contact with the limiting member 230; since the second positioning block 330 cannot move circumferentially, the circumferential movement of the handle portion 220 is limited; in this way, the installation operation of the blade body 200 is completed.

[0036] When the blade body 200 is disassembled: Step ④: Push the push kit 420, and use the push kit 420 to push the sliding ring 340 to move toward the inner bottom direction of the installation cavity 310 through the push pin 430. The sliding ring 340 and the second positioning block 330 are connected to each other through the connecting pin 360, so the second positioning block 330 also moves toward the inner bottom direction of the installation cavity 310 synchronously, so that the second positioning block 330 releases the restriction on the limiter 230, that is, the second positioning block 330 releases the circumferential movement restriction on the blade body 200; Step ⑤: The blade body 200 is moved circumferentially to rotate until the limiting member 230 is aligned with the preset gap 380. At this time, the notch portion 240 is released from the mutual engagement with the first positioning block 320, that is, the first positioning block 320 releases the restriction on the axial movement of the blade body 200; Step ⑥: Pull the handle portion 220 out of the mounting shaft tube 300. At this time, the limit member 230 can pass through the preset gap 380 until the handle portion 220 and the mounting shaft tube 300 are separated from each other, thereby completing the disassembly operation of the blade body 200; then the push sleeve 420 is reset under the elastic force of the second spring 440, and the second positioning block 330 is also reset under the elastic force of the first spring 370.

[0037] This embodiment also discloses a medical plastic surgery mobile phone 100, including a blade mounting structure of any of the above embodiments. For the specific structure of the blade mounting structure, reference can be made to the above embodiments. Since the medical plastic surgery mobile phone 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0038] Among them, a transmission structure 500 is provided inside the medical plastic surgery mobile phone 100, and the transmission structure 500 is used to connect an external rotation drive device (not shown in the drawings) and install the shaft tube 300, so that the rotation drive device can drive the blade body 200 to perform corresponding movement through the transmission structure 500.

[0039] Embodiment 1: Reference Figure 9-11 In this embodiment, the blade body 200 is selected as a reciprocating saw, that is, when the blade body 200 performs a linear reciprocating motion along its own axis: The transmission structure 500 comprises a first eccentric assembly 510 and a first gear assembly 520; the first eccentric assembly 510 comprises a frame member 511 and a first eccentric wheel member 512 arranged on the inner side of the frame member 511; the central axis and the rotation axis of the first eccentric wheel member 512 are located on non-colinear lines; the inner side of the frame member 511 is provided with an activity space for the first eccentric wheel member 512 to perform eccentric rotational motion; the rotation driving device can drive the first eccentric wheel member 512 to perform reciprocating eccentric rotational motion through the first gear assembly 520, and during the eccentric rotational motion of the first eccentric wheel member 512, at least part of the outer side surface is kept in contact and connected with the inner side surface of the frame member 511; the mounting shaft tube 300 is slidably connected to the interior of the medical plastic surgery mobile phone 100 along its own axis, the first end of the mounting shaft tube 300 is connected to the handle portion 220, and the second end of the mounting shaft tube 300 is fixedly connected to the frame member 511.
