After adjusting the position, the second limiting plate 13 can be fixed again by tightening the second screw 15, so as to bend the needle 4.

[0064] Specifically, as shown in Figure 5 and Figure 7 , the connection between the groove 3 and the bending slot 2 is provided with an arc-shaped transition part, so as to ensure the bending smoothness of the needle tube and avoid breaking when bending.
[0065] The specific working principle of the needle 4 bending jig provided in the embodiment is as follows: when the needle 4 needs to be bent, the first screw 10 is loosened, the first limiting plate 5 is adjusted to move to a predetermined position in the second direction according to the bending angle requirement of the needle 4, and then the first screw 10 is tightened to fix the first limiting plate 5; at the same time, the second screw 15 is loosened, the second limiting plate 13 is adjusted to move to a predetermined position in the second direction according to the length requirement of the needle 4 at the bending part, and then the second screw 15 is tightened to fix the second limiting plate 13, so as to adjust the depth of the needle 4 inserted into the groove 3. First, one end of the needle 4 is inserted into the groove 3 until it abuts against the second limiting plate 13, as shown by the arrow in Figure 4 , then an acting force is applied to the other end towards the first limiting plate 5 until the needle 4 abuts against the limiting screw 7, as shown by the arrow in Figure 6 , and then the bending of the needle 4 is completed. After the bending is completed, the two ends of the needle 4 are trimmed according to the actual requirement to meet the requirement. The needle 4 bending jig provided in the embodiment can adapt to the needle 4 with different lengths and bending angles. The first scale 6 and the second scale 14 are used as references to ensure that multiple needles 4 are bent to form the same specification of needle 4, which has a wide range of applications and avoids the situation that the lengths of the manually bent needles 4 are not the same and the heights are uneven. The bending angle of the needle 4 is limited by the first limiting plate 5, which improves the precision and avoids the situation that the bending is too much and the needle 4 is broken, thereby reducing the cost.
[0066] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation on the embodiments. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the utility model creation.
