Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the accompanying drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0025] The names of the messages or information exchanged between multiple devices in the embodiments of the present invention are only used for illustrative purposes and are not used to limit the scope of these messages or information. Example 1

[0026] like Figure 1-8 The cam 24 has two cams 12 and 13 for locking the cam 12 in place, so that the cam 22 can be locked in place when the spring is unlocked, and the cam 24 has a lockhole 5 which is caused by the locking cam 12. When the cam 22 is unlocked, the cam 22 can be locked in place when the spring is unlocked. Example 2

[0027] like Figure 3-4 As shown, this embodiment is obtained by describing in detail the technical features such as the width of the base 1 on the basis of the first embodiment. The remaining technical features are the same as those of the first embodiment, and the similarities are not repeated here. Among them, the difference between this embodiment and the first embodiment is that the width of the base 1 is the same as the length of the wire B required to make the special-shaped spring.

[0028] In this embodiment, the width of the base 1 is the same as the length of the wire B required to make the special-shaped spring, so that the wire B can be cut to a fixed length to ensure that the length of the manufactured spring A meets the requirements. Example 3

[0029] like Figure 1 As shown, this embodiment is obtained by adding technical features such as an arc groove 8 on the basis of Example 2. The remaining technical features are the same as those of Example 2, and the similarities are not repeated here. Among them, the difference between this embodiment and Example 2 is that: an arc groove 8 is provided on the side of the bending block 4, and the diameter of the arc groove 8 matches the diameter of the wire B required to make the special-shaped spring.

[0030] In this embodiment, the side of the bending block 4 is provided with an arc groove 8 that matches the diameter of the wire B. When bending, the arc groove 8 is sleeved on the wire B, facilitating bending while preventing damage to the outer cylindrical surface of the bending part.

[0031] The overall technical solution formed by the above embodiments is used as follows: the base 1 is placed on the support platform, the limit block 2 is inserted into the corresponding through hole 7, the wire B required for making the special-shaped spring is placed at the gap 6, and the positioning block 3 is inserted into the corresponding through hole 7. The protrusion 5 is pressed on the wire B required for making the special-shaped spring, and the side of the protrusion 5 is in sliding contact with the bottom of the limit block 2;

[0032] Press the positioning block 3 downward from the top to compress the wire B required for making the special-shaped spring into the gap 6, and hold the bending block 4 to cooperate with the edge of the base 1 to cut the wire B required for making the special-shaped spring extending out of the base 1;

[0033] The bending block 4 is placed close to one side of the positioning block 3, and the arc groove 8 on the bending block 4 is against the wire material B required for making the special-shaped spring. The bending block 4 is moved from the positioning block 3 to the limit block 2, and the bending block 4 is close to the positioning block 3 and the limit block 2 to bend the two ends of the wire material B required for making the special-shaped spring;

[0034] Remove the bending block 4 and the pressing force on the positioning block 3 and remove the positioning block 3 to complete the production of the special-shaped spring.

[0035] Among them, the process of cutting the wire B required for making the special-shaped spring extending out of the base 1 is as follows: the edge of the bending block 4 is abutted and crossed with the edge of the base 1, and the bending block 4 is moved from top to bottom. The wire B required for making the special-shaped spring is cut through the cutting structure formed by the intersection of the edge of the bending block 4 and the edge of the base 1.
