[0038] Through the structural design of the adjustment mechanism, after the spiral spring is fixed, the angle of the spiral spring can be adjusted by rotating the rotating chassis 27. During the adjustment, the angle of the product itself can remain unchanged, so as to facilitate the alignment of the product and the spiral spring angle, and the engagement of the rotating column 25 and the first gear ring 26 can accurately control the rotation angle, so as to reduce the time required for adjustment and improve the efficiency of assembly. When working, first pull the two sets of clamping rods 48, and the second spring 50 sleeved on the clamping rod 48 will be compressed, so that the spiral spring is clamped and fixed by the elastic force of the second spring 50, and then the product is placed on the fixed chassis 30, and a placement groove 28 is opened on the fixed chassis 30 specifically for fixing the product, and then the rotating chassis 27 is rotated, and the first gear ring 26 sleeved on the outer side of the rotating chassis 27 is engaged with the rotating column 25, and the top of the rotating column 25 is engaged with the rotating column 25. The disc 42 is engaged, and the rotation of the rotating chassis 27 can be transmitted to the rotating disc 42 through the rotating column 25. The rotating disc 42 can rotate synchronously with the rotating chassis 27, which will be more convenient when adjusting the placement angle of the spiral spring. The bottom end of the rotating chassis 27 is connected to the connecting frame 35, and the connecting frame 35 is fixedly connected to the bearing 33 to facilitate the smooth rotation of the rotating chassis 27. When the rotating disc 42 rotates, the rotating block 40 at the bottom end thereof will slide in the rotating groove 39.

[0040] Through the structural design of the supporting mechanism, the two groups of supporting blocks 65 will be located below the limiting rod 47 before assembly, which can provide support for the bottom end of the spiral spring to prevent the spiral spring from falling from between the two groups of limiting rods 47. During the assembly process, the supporting blocks 65 can move to both sides to avoid obstruction to the spiral spring, thereby ensuring that the spiral spring can be smoothly pressed into the installation groove of the product. During operation, the two groups of supporting blocks 65 are located below the limiting rod 47. After the clamping rod 48 clamps and fixes the spiral spring, the supporting blocks 65 can provide support for the bottom end of the spiral spring to prevent the spiral spring from falling from between the two groups of limiting rods 47. When 42 moves downward, the push rod 63 at the top will push the sliding block 59 to move, and the sliding block 59 slides in the plug column 61. The support block 65 is connected to the sliding block 59 through the mounting rod 64. When the sliding block 59 moves, the support block 65 will also move accordingly and gradually move out from the bottom end of the spiral spring to ensure that the support block 65 will not affect the normal assembly of the spiral spring so that the spiral spring can be smoothly pressed into the product. The two sets of limit rods 47 have a certain angle with the central axis of the rotating disk 42 to ensure that the support block 65 will not be located on the moving path of the limit rod 47, and the limit rod 47 will not abut against the support block 65 when moving downward.

[0041] Further, the fixing mechanism includes a connecting column 58, the top of the connecting column 58 is rotatably connected to the bottom push rod 63, the bottom of the connecting column 58 is fixedly connected with two groups of rectangular blocks 54, one group of rectangular blocks 54 is fixedly connected to the arc plate 55, the top of the arc plate 55 is fixedly connected with a rubber block 57, the rubber block 57 is aligned with the through groove 66, the through groove 66 is provided on the device base 1, the top of the device base 1 does not contact the bottom of the rotating chassis 27, the bottom of the rotating chassis 27 is rotatably connected with multiple groups of cylindrical rollers 31, the bottom ends of the cylindrical rollers 31 abut against the top of the device base 1, the bottom end of the rotating chassis 27 is fixedly connected with a rubber ring 32, and the rubber ring 32 contacts the top of the device base 1;

[0042] Through the structural design of the fixing mechanism, when the support block 65 moves, the push rod 63 at the bottom will pull the connecting column 58 upward to move. When the connecting column 58 is lifted upward, the rubber block 57 will extend from the through groove 66 and abut against the rubber ring 32 fixed at the bottom end of the rotating chassis 27, so that the rotating chassis 27 can be fixed through the friction between the top end of the rubber block 57 and the rubber ring 32, so as to avoid the rotating chassis 27 from rotating during assembly, resulting in the spiral spring being unable to be accurately installed into the product. When working, when the top push rod 63 pushes the sliding block 59 to move, the push rod 63 fixed on the bottom end of the sliding block 59 will be pulled by the sliding block 59 and move upward, and the bottom push rod 63 is connected with the connecting column 58, which will connect the connecting column 5 8 is pulled upward, two groups of rectangular blocks 54 are fixed to the bottom end of the connecting column 58, one group of rectangular blocks 54 is connected to the arc plate 55, and a rubber block 57 is fixed to the arc plate 55. The rubber block 57 will extend from the through groove 66 and abut against the rubber ring 32 fixed at the bottom end of the rotating chassis 27, so that the friction force of the rotating chassis 27 during rotation is increased through the abutment between the rubber ring 32 and the rubber block 57, thereby fixing the rotating chassis 27 to ensure that the rotating chassis 27 will not rotate due to accidental contact during assembly of the scroll spring, so that the scroll spring can be accurately pressed into the installation groove of the product, and multiple groups of cylindrical rollers 31 are rotatably connected to the bottom end of the rotating chassis 27, and the cylindrical rollers 31 can keep the rotating chassis 27 stable during rotation.

When the first-stage cylinder 21 and the second-stage cylinder 22 are retracted, the fixed disc 37 can be reset under the action of the first spring 44, wherein the top end of the support column 45 is T-shaped, which can limit the protrusion 36 to prevent the protrusion 36 from moving upward and sliding out of the support column 45. At the same time, the support column 45 can also guide the movement of the fixed disc 37 to ensure the stable movement of the fixed disc 37 and the rotating disc 42.

[0045] Furthermore, a washer 60 is fixedly connected to one side of the sliding block 59 away from the mounting rod 64, and the washer 60 is made of rubber;
