Figure 1 As shown, the limiting hoop 106 positions the steel wire during the winding process;

[0029] A guide rail 107 is fixedly installed on one side of the top surface of the base 101, and a clamping block 109 is slidably connected to the inside of the guide rail 107. The inner wall of the top of the clamping block 109 is rotatably connected to a wheel 110. The wheel 110 and the limiting hoop 106 are located on the same plane. The top surface of the base 101 and one end close to the guide rail 107 are fixedly connected to a support member 2 108. The inner wall of the support member 2 108 is threadedly connected to a long bolt 111. One end of the long bolt 111 extends to the inside of the guide rail 107, and the end of the long bolt 111 is against the surface of the clamping block 109.

[0032] The working principle of this utility model:

[0033] When the device is in use, the end of the steel wire is inserted from top to bottom between the two limiting hoops 106, and the long bolt 111 is rotated. The long bolt 111 moves along the inner wall of the second support member 108, so that the end of the long bolt 111 pushes the clamping block 109 to move in the guide rail 107, and the wheel 110 presses the steel wire tightly against the inner side of the limiting hoops 106;

[0034] Then, the crank 104 is rotated to drive the rotating sleeve 103 to rotate, and the steel wire is gradually wound around the outer side of the rotating sleeve 103. The end of the steel wire contacts the end of the second long bolt 202 during the movement and is guided by the end of the second long bolt 202, so that the spring forms a pitch during the winding process.

[0035] During the winding process, the spring is wound to the outside of the support rod 302, and the support block 303 contacts the inside of the spring, thereby shaping the spring;

[0036] When adjusting the spring forming pitch, rotate the long bolt 202 in the support part 3 201, so that the distance between the end of the long bolt 202 and the limit hoop 106 changes, and then tighten the nut 203 to make it press against the support part 3 201 to prevent the long bolt 202 from moving. Secondly, rotate the support part 3 201 as a whole to adjust the direction of the end of the long bolt 202. When fixing, tighten the screw 112, and the pressure plate 113 is pressed down on the fixed disk 204. The washer 205 on the top of the fixed disk 204 increases the friction between it and the pressure plate 113, thereby completing the locking.

[0037] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
