Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figures 1 to 7 As shown, an injection device for facial lifting in medical aesthetics includes a handle 1. A waterproof tactile switch 2 is fixedly connected to the left side of the handle 1. A waterproof battery box 3 is fixedly connected to the inner wall of the handle 1. A rectangular box 4 is fixedly connected to the upper surface of the handle 1. A U-shaped plate 5 is fitted to the inner wall of the rectangular box 4. A moving mechanism 6 is fixedly connected to both the left side of the inner wall of the U-shaped plate 5 and the inner wall of the rectangular box 4. The waterproof tactile switch 2 and the waterproof battery box 3 are electrically connected to the moving mechanism 6 via wires. A left baffle 7 is fixedly connected to the left side of the U-shaped plate 5. A right baffle 8 is fixedly connected to the right side of the box body 4. A circular hole 9 is opened inside the left baffle 7. A syringe 10 is attached to the inner wall of the circular hole 9 and the left side of the right baffle 8. A C-shaped spring 11 is attached to the surface of the syringe 10. A positioning block 12 is fixedly connected to the upper surface of the C-shaped spring 11. The left and right sides of the left baffle 7 and the upper surface of the syringe 10 are attached to the surface of the positioning block 12. A connecting plate 13 is fixedly connected to the upper surface of the positioning block 12. The elastic force of the C-shaped spring 11 is greater than the sum of the weights of the positioning block 12 and the connecting plate 13.

[0029] The moving mechanism 6 includes a mounting base 61, a micro motor 62, a drive plate 63, a threaded post 64, a threaded cylinder 65, a connecting ring 66, and a connecting post 67. The bottom of the mounting base 61 is fixedly connected to the inner wall of the rectangular box 4. The upper surface of the mounting base 61 is fixedly connected to the bottom of the micro motor 62. The output end of the micro motor 62 is fixedly connected to the right end of the threaded post 64. The surface of the threaded post 64 is threadedly connected to the inner wall of the threaded cylinder 65. The surface of the threaded cylinder 65 is fixedly connected to the inner wall of the connecting ring 66. The left and right ends of the connecting post 67 are fixedly connected to the left side of the connecting ring 66 and the left side of the inner wall of the U-shaped plate 5, respectively. The right side of the mounting base 61 is fixedly connected to the left side of the drive plate 63. The micro motor 62, the waterproof tactile switch 2, and the waterproof battery box 3 are all electrically connected to the drive plate 63 through wires.

[0030] The syringe 10 includes a syringe 101, a puncture needle 102, a piston 103, a plunger 104, a first cylinder 105, and a first ring 106. The surface of the syringe 101 is attached to the inner wall of the puncture needle 102, the inner wall of the syringe 101 is attached to the surface of the piston 103, the right side of the piston 103 is bonded to the left side of the plunger 104, the right side of the plunger 104 is attached to the left side of the right baffle 8, the inner wall of the first cylinder 105 is fixedly connected to the surface of the syringe 101, the inner wall of the first ring 106 is fixedly connected to the surface of the syringe 101, the surface of the first cylinder 105 is attached to the inner wall of the circular hole 9, both the left and right sides of the first cylinder 105 are attached to one side of the C-shaped spring 11, the other side of the C-shaped spring 11 is attached to the side of the first ring 106, and the upper surface of the first cylinder 105 and the upper surface of the first ring 106 are attached to the bottom of the positioning block 12.

[0031] It should be noted that the moving mechanism 6 is powered by a battery in the battery box, and the two waterproof tactile switches 2 on the handle 1 control the forward or reverse rotation of the micro motor 62 on the moving mechanism 6. When the micro motor 62 rotates forward, it drives the threaded column 64 to rotate, and through the cooperation of the threaded column 64 and the threaded cylinder 65, it moves the U-shaped plate 5 to the right. When the micro motor 62 rotates in reverse, it drives the threaded column 64 to rotate, and through the cooperation of the threaded column 64 and the threaded cylinder 65, it moves the U-shaped plate 5 to the left. When the C-shaped spring... After the piece 11 is fitted onto the syringe 101, the elasticity of the C-shaped spring piece 11 prevents it from automatically separating from the syringe 101. Then, the C-shaped spring piece 11 is positioned by the first cylinder 105 and the first ring 106, and the syringe 101 is fixed in the round hole 9 of the left baffle 7 by the positioning block 12. When the left baffle 7 moves to the right, the syringe 101 moves to the right by the left baffle 7, and the fat cells in the syringe 101 are discharged through the puncture needle 102 by the cooperation of the right baffle 8, the piston 103 and the push rod 104.

[0032] like Figures 1 to 4 As shown, sealing rings 14 are bonded to the right side of the left baffle 7 and the surface of the U-shaped plate 5.

[0033] It should be noted that when the sealing ring 14 on the U-shaped plate 5 comes into contact with the rectangular box 4, the opening on the left side of the rectangular box 4 is sealed by the sealing ring 14 and the U-shaped plate 5. Thus, when the injection device is idle, water cannot enter the rectangular box 4 by contacting the sealing ring 14 with the rectangular box 4.

[0034] like Figures 1 to 9As shown, a second cylinder 15 is fixedly connected to the left side of the handle 1, a cylinder 16 is fixedly connected to the inner wall of the second cylinder 15, a rubber ring 17 is bonded to the surface of the cylinder 16, a second ring 18 is attached to the right side of the rubber ring 17, the left side of the second cylinder 15 and the surface of the cylinder 16, and a vertical plate 19 is fixedly connected to the surface of the second ring 18.

[0035] It should be noted that, through the cooperation of the cylinder 16 and the second ring 18, the vertical plate 19 can rotate around the cylinder 16. And through the friction between the rubber ring 17 and the second ring 18, the vertical plate 19 can automatically stop at the designated position after the user stops pushing it. At the same time, when the vertical plate 19 is in a vertical state, it can cover one of the waterproof touch switches 2. Thus, when injecting fat cells, only the designated waterproof touch switch 2 can be pressed, thereby preventing the syringe 10 from moving to the left due to accidental activation of the other waterproof touch switch 2.

[0036] The working principle of this utility model is as follows: First, the syringe 10 containing fat cells is inserted into the round hole 9. Then, the C-shaped spring 11 is put on the syringe 101. The elasticity of the C-shaped spring 11 prevents the C-shaped spring 11 from automatically separating from the syringe 101. At the same time, the C-shaped spring 11 is positioned by the first cylinder 105 and the first ring 106, and the syringe 101 is fixed in the round hole 9 of the left baffle 7 by the positioning block 12.

[0037] After the syringe 10 is fixed together with the left baffle 7, the micro motor 62 is turned forward by pressing the designated waterproof tactile switch 2. At this time, the micro motor 62 drives the threaded column 64 to rotate, and through the cooperation of the threaded column 64 and the threaded cylinder 65, the U-shaped plate 5 moves to the right. When the right baffle 8 contacts the push rod 104, the waterproof tactile switch 2 is released, the micro motor 62 stops rotating, and the syringe 10 no longer moves to the right.

[0038] Then, the tip of the puncture needle 102 is inserted into the facial skin tissue, and the micro motor 62 is rotated forward by pressing the designated waterproof tactile switch 2. At this time, the micro motor 62 drives the threaded column 64 to rotate, and through the cooperation of the threaded column 64 and the threaded cylinder 65, the left baffle 7 moves to the right. Through the cooperation of the right baffle 8, the piston 103 and the push rod 104, the fat cells in the syringe 101 are discharged through the puncture needle 102. At the same time, during the injection process, the syringe 101 will drive the puncture needle 102 to retract.

[0039] After the injection is completed, release the waterproof tactile switch 2 and pull out the puncture needle 102. Then, press another waterproof tactile switch 2 to reverse the micro motor 62. At this time, the micro motor 62 drives the threaded column 64 to rotate, and through the cooperation of the threaded column 64 and the threaded cylinder 65, the left baffle 7 is moved to the initial position. Then, remove the C-shaped spring 11 from the syringe 101 and separate the syringe 101 from the left baffle 7.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
