[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0018] according to Figure 1 ,2 As shown in Figure 3, this embodiment provides a needle holder with positioning grooves for a split multi-needle injection system, comprising a barrel 1, a No. 1 connecting block 2 and a protective cap 3. One end of the barrel 1 is connected to a No. 1 connecting block 2, and the other end of the barrel 1 is engaged with a protective cap 3. One end inside the barrel 1 is provided with a positioning mechanism matching the needle, and a connecting mechanism is provided between multiple No. 1 connecting blocks 2. A through hole 10 is provided inside the No. 1 connecting block 2. When the injection needle holder is in use, the protective cap 3 is first installed on the other end of the barrel 1, and then the multiple No. 1 connecting blocks 2 are fixed together by the connecting mechanism so that the multiple barrels 1 are connected to each other. Then, one end of the protective cap 3 is aligned with the position where injection is required, and multiple injection needles are inserted from one end of the multiple barrels 1. The barrel 1 and the positioning mechanism cooperate to position the needles to prevent the needles from tilting when injecting cosmetic drugs.

[0019] The interior of the protective cap 3 is connected to a limiting tube 4, and the shape of the limiting tube 4 is set to a conical structure. The protective cap 3 and one end of the barrel 1 are provided with a snap-fit ​​mechanism, and the snap-fit ​​mechanism includes an elastic clip 5 and a protrusion 6. The inner side of the protective cap 3 is symmetrically connected with the elastic clip 5, and the outer wall of the elastic clip 5 is provided with a plurality of protrusions 6. The material of the elastic clip 5 is set to elastic plastic. The two elastic clips 5 on the inner side of the protective cap 3 are pressed inwardly to shrink so that the distance between them is smaller than the diameter of the barrel 1, so as to insert the elastic clip 5 into the interior of the barrel 1, and then the elastic clip 5 uses its own elastic reset to be tightened together with the inner wall of the barrel 1, so as to fix the protective cap 3 at the other end of the barrel 1. The protrusion 6 on the elastic clip 5 can increase the friction between its outer wall and the inner wall of the barrel 1, so that the protective cap 3 is fixed more firmly, and the limiting tube 4 connected to the inner side of the protective cap 3 is just on the center line of the inside of the barrel 1, and can also play a role in positioning the needle.

[0020] The positioning mechanism includes a retaining ring 7, a spring 8 and a sliding sleeve 9. The sliding sleeve 9 is slidably installed at one end of the cylinder 1, and a retaining ring 7 is provided at the other end of the cylinder 1. A spring 8 is connected between the retaining ring 7 and the sliding sleeve 9. The needle is inserted into the cylinder 1 through the through hole 10 on the No. 1 connecting block 2. The needle will first be sleeved together with the sliding sleeve 9 inside the cylinder 1 and squeezed into the cylinder 1 together. At this time, the needle has been deeply sunken into the cylinder 1, and the cylinder 1 locks the position of the needle. The cylinder 1 plays a positioning role for the needle, and the spring 8 is in a compressed state. After the needle injection work is completed, the needle withdraws from the inside of the cylinder 1 and no longer squeezes the sliding sleeve 9. The elastic force generated by the spring 8 is used to drive the sliding sleeve 9 to move outward and reset.

[0021] A support tube 11 is provided inside the cylinder 1, one end of the support tube 11 is fitted and connected to the inner side of the protective cap 3, and the other end of the support tube 11 is fitted and connected to the inner side of the sliding sleeve 9. When the positioning groove needle seat has not been used, the protective cap 3 can be directly pulled out from the other end of the cylinder 1, and then the support tube 11 is inserted into the cylinder 1, and then the protective cap 3 is inserted back into the other end of the cylinder 1. Because the two ends of the support tube 11 are respectively fitted and connected to the protective cap 3 and the sliding sleeve 9, the support tube 11 supports the sliding sleeve 9, thereby preventing the sliding sleeve 9 from arbitrarily expanding and contracting the spring 8 due to external force, resulting in its elasticity being weakened.

[0022] The connection mechanism includes a clamping block 12, a No. 2 connection block 13, a threaded rod 14 and a nut 15. The clamping blocks 12 are symmetrically arranged on both sides of the No. 1 connection block 2. The top and bottom ends of the clamping blocks 12 are symmetrically connected with the No. 2 connection block 13. A threaded rod 14 is passed through the No. 2 connection blocks 13 adjacent to each other on the left and right. The two ends of the threaded rod 14 are symmetrically threaded with nuts 15. A rectangular groove is arranged inside the clamping block 12. The outer wall of one side of the No. 1 connection block 2 is fitted and connected with the inner part of the rectangular groove. The width of the rectangular groove is equal to the width of the outer wall of one side of the No. 1 connection block 2. The multiple cylinders 1 are arranged in a row. The No. 1 connecting blocks 2 at one end are put together, and then the clamping blocks 12 are inserted into the outer walls of the No. 1 connecting blocks 2 on both sides. The inner walls of the rectangular grooves inside the clamping blocks 12 are engaged with the outer walls of the No. 1 connecting blocks 2. Then, the threaded rods 14 are used to penetrate the No. 2 connecting blocks 13 at the top and bottom ends of the clamping blocks 12, and the nuts 15 are tightened at both ends of the threaded rods 14. The nuts 15 squeeze the two clamping blocks 12 close to each other to clamp the multiple No. 1 connecting blocks 2, thereby connecting the multiple cylinders 1 to each other. When the connection needs to be released, just unscrew the nuts 15 and then pull out the clamping blocks 12.

[0023] The injection needle holder is inserted into the interior of the barrel 1 by passing the needle through the through hole 10 on the No. 1 connecting block 2. The needle will first be sleeved together with the sliding sleeve 9 inside the barrel 1 and squeezed into the interior of the barrel 1. At this time, the needle has been deeply sunken into the barrel 1, and the barrel 1 locks the position of the needle. The barrel 1 plays a positioning role for the needle, and the spring 8 is in a compressed state. After the needle injection work is completed, the needle withdraws from the interior of the barrel 1 and no longer squeezes the sliding sleeve 9. The elastic force generated by the spring 8 is used to drive the sliding sleeve 9 to move outward and reset.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
