[0032] The needle assembly 3 comprises a column barrel 301 slidably inserted into the mounting groove 2, a telescopic positioning ring 302 is provided at one end of the column barrel 301, a connecting needle 303 is installed through the other end of the column barrel 301, one end of the connecting needle 303 is connected with a flow tube 304 arranged in the column barrel 301, a shunt needle 305 which passes through the end of the column barrel 301 is slidably sleeved on the flow tube 304, and a driving member 306 for driving the shunt needle 305 to reciprocate is installed on the column barrel 301. The driving member 306 can be used to adjust the position of the shunt needle 305 in the column barrel 301, so as to change the distance between the end of the shunt needle 305 and the end of the column barrel 301, so as to adjust the depth of penetration into the skin, ensure safety, and increase injection accuracy. Changing the traditional single needle to multiple needles can increase injection efficiency, reduce the time for personnel to endure pain, and improve practicality;

[0033] The clamping positioning member 4 includes a connecting frame 401 constructed on one side of the installation groove 2, a spring clamping column 402 is installed in the connecting frame 401, a clamping groove 403 for engaging with the spring clamping column 402 is constructed on the column barrel 301, and a pressing member 404 is provided in the connecting frame 401 for pushing the spring clamping column 402 out of the clamping groove 403. Traditional needle positioning mostly adopts a sleeve structure, and the needle part is easy to be detached, and the stability is poor. Therefore, the spring clamping column 402 is used to position the column barrel 301, which can increase the stability after connection, and when replacement is needed, it is only necessary to press the pressing member 404 to push the spring clamping column 402 out of the clamping groove 403, which is convenient to operate.

[0034] like Figure 4-Figure 5As shown, in some embodiments, a ring groove 201 is constructed at the inner end of the mounting groove 2, an electromagnet ring 202 is fixedly connected in the ring groove 201, a stepped groove 3011 is constructed at one end of the column barrel 301, a metal ring 203 for plugging with the electromagnet ring 202 is fixedly connected in the stepped groove 3011, and the electromagnet ring 202 arranged in the ring groove 201 is used to attract the metal ring 203, which can effectively achieve the connection effect, and the magnetic attraction effect can ensure that the column barrel 301 is tightly inserted into the mounting groove 2, thereby ensuring the connection position after the needle is replaced.

The setting of the connecting block 204 and the groove 2031 is used to prevent the column 301 from rotating after connection, thereby increasing stability.

[0036] like Figure 6 As shown, in some embodiments, the spring clamping column 402 includes a column rod 4021 that slides through the connecting frame 401, one end of the column rod 4021 is connected to the inner end of the connecting frame 401 with a return spring 4022, a movable groove 4023 is constructed on the column rod 4021, and the pressing piece 404 includes a shaft rod 4041 fixedly connected to the connecting frame 401, a lever 4042 with one end movably inserted in the movable groove 4023 is hinged on the shaft rod 4041, and a pressing column 4043 that is abutted against the other end of the lever 4042 is installed on the connecting frame 401. The pressing column 4043 is arranged opposite to the column rod 4021. When the needle assembly 3 needs to be replaced, the column barrel 301 can be first inserted into the installation groove 2, and the electromagnetic The iron ring 202 attracts the metal ring 203 to move toward the inside of the installation groove 2, and at the same time, the side with the snap-fit ​​groove 403 is inserted toward the direction of the column 4021. After insertion, the groove 2031 on the metal ring 203 is used to connect and position with the connecting block 204, so that the column 4021 can be pushed into the snap-fit ​​groove 403 by the thrust of the reset spring 4022, thereby completing the snap-fit ​​limit and improving the stability after connection. When it needs to be disassembled, it is only necessary to push the pressing column 4043 to drive the lever 4042 to flip around the shaft 4041, so that the other end of the lever 4042 drives the column 4021 to disengage from the snap-fit ​​groove 403 in the movable groove 4023. The pressing operation is more convenient and improves practicality.

[0037] like Figure 3As shown, in some embodiments, a side groove 3012 is constructed at one end of the column 301, and the telescopic positioning ring 302 includes a ring plate 3021 slidably mounted in the side groove 3012, and a support spring 3022 is connected between one end of the ring plate 3021 and the inner end of the side groove 3012, and the other end of the ring plate 3021 is constructed with an arc edge.

It should be noted that the inner diameter of the connecting needle 303 is smaller than the inner diameter of the expansion tube 3033. The conical expansion disk 3032 can collect the essence flowing through the connecting needle 303 and then transport it to the expansion tube 3033, so as to ensure that the expansion tube 3033 can provide essence to multiple arc needles 3052 at the same time, so as to ensure that the arc needles 3052 can inject essence at the same time after piercing the skin.

[0039] like Figure 3 As shown, in some embodiments, the outer surface of the sleeve 3051 is configured with an external thread, and the driving member 306 includes a semicircular frame 3061 configured on the cylinder 301, and an adjusting ring block 3062 threadedly mounted on the sleeve 3051 is rotatably installed in the semicircular frame 3061.
