The guide arm includes a second rod-shaped body 21, similarly to the first rod-shaped body 11, the second rod-shaped body 21 is also columnar as a whole, its cross section may be circular, rectangular, elliptical, etc., and the length of the second rod-shaped body 21 is 5-10cm, when the cross section of the second rod-shaped body 21 is rectangular, the aspect ratio of the rectangle is 1-3: 1. the second rod-shaped main body 21 is provided with a second hinge portion 22 and a second fixing portion 23, and the second hinge portion 22 is located at the head end of the second rod-shaped main body 21, and the second fixing portion 23 is separated from the second hinge portion 22 by a second length, that is, the distance between the second fixing portion 23 and the head end of the second rod-shaped main body 21 is the second length.
In the present embodiment, the reference arm and the guide arm are hinged together by the first hinge portion 12 and the second hinge portion 22. The first hinge 12 and the second hinge 22 may specifically be configured by using existing hinge structures, such as existing scissors, walnut clips, etc., which are not described herein.
Both ends of the angle adjusting assembly 30 are pivotally connected to the first fixing portion 13 and the second fixing portion 23, respectively, and the angle adjusting assembly 30 adjusts the included angle between the first rod-shaped body 11 and the second rod-shaped body 21 (i.e., the reference arm and the guide arm) by changing the length thereof.
When the facial injection auxiliary device is used for injecting the filling material, the included angle between the reference arm and the guide arm is adjusted through the angle adjusting component according to the type and the injection position of the filling material (such as hyaluronic acid, botulinum toxin and the like), then the reference arm is attached to the epidermis, the head end of the reference arm is close to the injection position, then the injector with the filling material is attached to the guide arm, and the needle head of the injector is completely pricked into the skin and the filling material is pushed to the corresponding level. Under the condition that the needle head of the injector has a certain length, the needle point can reach different subcutaneous depths by flexibly and accurately controlling the angle of the needle (namely the included angle between the reference arm and the guide arm), thereby comprehensively improving the accuracy of injection and the satisfaction of customers. For example, for mid-face injection, the angle between the reference arm and the guide arm is adjusted to 10-15 °, so that the filling material can be injected into the intradermal layer more accurately; the included angle between the reference arm and the guide arm is adjusted to 30-40 degrees, so that the filling material can be precisely injected into the subcutaneous layer; the included angle between the reference arm and the guide arm is adjusted to 90 degrees, so that the filling material can be precisely injected into the muscle layer or periosteum layer.
In one embodiment of the present utility model, angle adjustment assembly 30 includes a turntable 31 and N telescoping tubes 32, where N is an integer greater than or equal to 2. The outer circumferential surface of the turntable 31 has angle scales, and the angle scales are uniformly distributed along the circumferential direction of the turntable 31. The turntable 31 is hollow and tubular, and the N telescopic tubes have different thicknesses and are nested in the tube cavity of the turntable 31 in a coaxial mode.
The central axes of the turntable 31 and the N telescopic tubes 32 are located in the plane where the centers of the first rod-shaped body 11 and the second rod-shaped body 21 are located, or the central axes of the turntable 31 and the N telescopic tubes 32 are parallel to the plane where the centers of the first rod-shaped body 11 and the second rod-shaped body 21 are located; the angle adjusting assembly 30 changes its own length by the relative axial sliding between the telescopic tubes 32 and the axial sliding of the telescopic tubes 32 relative to the turntable 31, so that the angle between the first rod-shaped body 11 and the second rod-shaped body 21 correspondingly changes.
Accordingly, the first fixing portion 13 is located on the side of the first rod-shaped body 11 facing the second rod-shaped body 21, and the second fixing portion 23 is located on the side of the second rod-shaped body 12 facing the first rod-shaped body 11. Specifically, the first fixing portion 13 may be constituted by the first lug 14 protruding from the inner side surface of the first rod-shaped body 11 (i.e., the side surface facing the second rod-shaped body 21), the second fixing portion 23 may be constituted by the second lug 24 protruding from the inner side surface of the second rod-shaped body 21 (i.e., the side surface facing the first rod-shaped body 11), and the first length and the second length may be equal. Of course, in practical applications, the first fixing portion 13 and the second fixing portion 23 may be located on the same side of the first rod-shaped body 11 and the second rod-shaped body 21.

Meanwhile, since the two ends of the angle adjusting component 30 are pivoted with the first rod-shaped main body 11 and the second rod-shaped main body 21 respectively, when the included angle between the first rod-shaped main body 11 and the second rod-shaped main body 21 changes, the two ends of the angle adjusting component 30 can still be ensured to be stably connected with the first rod-shaped main body 11 and the second rod-shaped main body 21.
In one embodiment of the present utility model, the number N is an even number, and the number N of telescopic tubes 32 is divided into two groups, each group of telescopic tubes includes N/2 telescopic tubes 32 nested with each other, the first ends of the two groups of telescopic tubes are respectively connected to two ends of the turntable 31 (respectively nested in the turntable 31), and the second ends of one group of telescopic tubes are hinged to the first fixing portion 13 on the first rod-shaped main body 11, and the second ends of the other group of telescopic tubes are hinged to the second fixing portion 23 on the second rod-shaped main body 21.
With the above structure, when the turntable 31 is waved, the telescopic lengths of the telescopic tubes 32 on both sides are simultaneously changed, so that the rapid adjustment of the included angle between the first rod-shaped body 11 and the second rod-shaped body 21 can be realized.
In another embodiment of the present utility model, as shown in fig. 5, the angle adjusting assembly 30 includes a first telescopic rod 33 and a second telescopic rod 34, and the first telescopic rod 33 or the second telescopic rod 34 has an angle scale.

For example, when the angle scale is located on the second telescopic rod 34, the first telescopic rod 33 is provided with a through groove 331 arranged along the length direction, and the second telescopic rod 34 is embedded in the through groove 331, and the self length of the angle adjusting assembly 30 is changed by adjusting the nesting depth.
In particular, the first telescopic link 33 or the second telescopic link 34 has a set screw 35 thereon, and the angle adjusting assembly 30 maintains its length by the set screw 35, so that the angle between the first rod-shaped body 11 and the second rod-shaped body 21 is maintained unchanged.
In practical applications, the number of telescopic rods in the angle adjusting assembly 30 may be increased, and the first rod-shaped main body 11 and the second rod-shaped main body 21 may be sequentially nested through the telescopic rods, so as to adjust the included angle between them.
In one embodiment of the present utility model, as shown in fig. 6, in order to improve the stability of the guide arm guiding the syringe, the surface of the second rod-shaped body 21 facing away from the first rod-shaped body 11 is provided with a guiding groove 24, and the guiding groove 24 is disposed along the length direction of the second rod-shaped body 21. In use, a portion of the syringe may be inserted into the guide slot 24.
In addition, in order to improve the stability of the reference arm against the skin of the human body, in one embodiment of the present utility model, the first rod-shaped body 11 has an attaching plate 14 on a side facing away from the second rod-shaped body 21, and the attaching plate 14 has a width larger than that of the first rod-shaped body 11, so that the contact area of the reference arm with the skin of the human body is larger.
The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
