[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0029] like Figure 1-Figure 4 As shown, an obstetric forceps for obstetric delivery comprises a left handle 1 and a right handle 2. A connecting plate 3 is arranged on the outer side of the left handle 1 and the right handle 2. The two groups of connecting plates 3 are hinged to each other. The outer sides of the connecting plates 3 are fixedly connected with elastic connecting plates 4. The ends of the elastic connecting plates 4 away from the connecting plates 3 are fixedly connected with blades 5. The inner sides of the two groups of elastic connecting plates 4 are connected with pull ropes 18. A tightening mechanism is installed inside the left handle 1, and the tightening mechanism can bring the elastic connecting plates 4 together.

[0030] When in use, the left handle 1 and the right handle 2 are put together, and under the action of the elastic connecting plate 4, the blade 5 can swing relative to the left handle 1 and the right handle 2. Therefore, no matter how large the clamping angle is, the left handle 1 and the right handle 2 can be put together, and force application is convenient. At the same time, the blade 5 swings relative to the left handle 1 and the right handle 2. The blade 5 can swing with the baby's head, and when used in conjunction with the elastic connecting plate 4, it can fit the baby's head more closely, and the use stability is high;

[0031] After the left handle 1 and the right handle 2 are closed together, the two sets of elastic connecting plates 4 are closed together through the tightening mechanism, so that the clamping force can be accurately controlled for a second time, and the user comfort is high.

[0032] like Figure 2-Figure 4 As shown, in some embodiments, the tightening mechanism includes a mounting frame 8 arranged inside the left handle 1, a reel 9 is rotatably mounted on one side of the mounting frame 8 close to the inside of the left handle 1, a reel 17 is wound around the outside of the reel 9, a transmission shaft 12 is rotatably mounted on the other side of the mounting frame 8, a sliding shaft 13 is plugged into the transmission shaft 12, a keyway is provided on the inner wall of the transmission shaft 12, a key is provided on the outer side of the sliding shaft 13, the key is plugged into the keyway, a screw rod 14 is fixedly connected to the outer side of the sliding shaft 13, a nut rack 15 is provided on the outer side of the left handle 1, a threaded hole is provided inside the nut rack 15, and the screw rod 14 is threadedly connected in the threaded hole;

[0033] It also includes a draw rope 18 fixedly connected to the inner side of the elastic connecting plate 4 , and two sets of draw ropes 18 are both connected to the winding rope 17 .
