[0021] An embodiment of the utility model discloses a non-slip hairpin. As Figures 1-3 shown, it includes a first connecting piece 1 and a second connecting piece 2. Connecting plates are integrally formed on both opposite side edges of the first connecting piece 1, and hinge plates are integrally formed on both opposite side edges of the second connecting piece 2. The two connecting plates and the two hinge plates are respectively in contact with each other, and a rotating shaft is connected between the two connecting plates and the two hinge plates. The first connecting piece 1 and the second connecting piece 2 can rotate relative to each other through the rotating shaft. At the same time, a torsion spring is connected between the first connecting piece 1 and the second connecting piece 2. The torsion spring is sleeved on the rotating shaft, and the two ends of the torsion spring are respectively connected to the opposite surfaces of the first connecting piece 1 and the second connecting piece 2. When people pinch open the first connecting piece 1 and the second connecting piece 2, the torsion spring can reset the first connecting piece 1 and the second connecting piece 2. In addition, a first clip 3 is fixedly connected to the first connecting piece 1, and a second clip 4 is fixedly connected to the second connecting piece 2. The first connecting piece 1 and the first clip 3 can be fixed together by bonding, and the second connecting piece 2 and the second clip 4 can be fixed together by bonding. The first clip 3 and the second clip 4 are in contact with each other. When people wear the hairpin, they firmly hold one end of the first connecting piece 1 and the second connecting piece 2, separate the first clip 3 and the second clip 4, and then insert the first clip 3 and the second clip 4 into the hair. After releasing the hand, the first clip 3 and the second clip 4 clamp the hair. In addition, in order to facilitate people to better hold the first connecting piece 1 and the second connecting piece 2, convex portions 12 are integrally formed on both opposite sides of one end of the first connecting piece 1 and the second connecting piece 2.

[0022] In addition, receiving grooves 32 are formed on the opposite surfaces of the first clip 3 and the second clip 4. The first connecting piece 1 and the second connecting piece 2 are both embedded in the two receiving grooves 32. The receiving grooves 32 can accommodate the first connecting piece 1 and the second connecting piece 2, making the opposite surfaces of the first clip 3 and the second clip 4 smoother. In addition, a plurality of convex points 34 are integrally formed in the receiving groove 32 of the first clip 3. The convex points 34 can improve the connection firmness between the first connecting piece 1 and the first clip 3. In addition, positioning blocks 33 are integrally formed in the receiving grooves 32 of the first clip 3 and the second clip 4.
