[0028] The clamping unit 3 is arranged in the circular groove 10, and the clamping unit 3 includes a fixed plate 31, and the fixed plate 31 is provided with sliding grooves 311 in a circumferential array, and a column 32 is slidably arranged in the sliding groove 311, and a support plate 324 is arranged on the column 32;

[0029] A turntable 35 is rotatably disposed at the axis of the fixed plate 31 and is located directly below the fixed plate 31. The turntable 35 is provided with an inclined groove 351 corresponding to the slide groove 311. A slide bar 34 is provided between the inclined groove 351 and the slide groove 311. The slide bar 34 cooperates with the column 32.

[0030] The transmission unit 4 is disposed on the base frame 1 and cooperates with the turntable 35 . The transmission unit 4 drives the turntable 35 to rotate and controls the slide bar 34 to slide along the slide groove 311 to approach or move away from the axis of the fixed plate 31 .

[0031] Specifically, circular grooves 10 are provided in a linear array on the base frame 1, and at least four circular grooves 10 are provided. The number of the relative clamping units 3 is consistent with the number of the circular grooves 10. The more clamping units 3 are, the more springs can be set at one time, thereby improving the efficiency of spring setting. A side cover plate 12 that cooperates with the rotating rod 43 is provided on one side of the base frame 1. The fixed plate 31 is provided with a sliding groove 311 in a circumferential array. A column 32 is slidably provided in the sliding groove 311. A support plate 324 is provided on the column 32. The turntable 35 is rotatably provided at the axis center of the fixed plate 31 and is located directly below it. The turntable 35 is provided with an inclined groove 351 corresponding to the sliding groove 311, and the inclined groove 351 is aligned with the sliding groove 311. A slide bar 34 is arranged between the two, and the slide bar 34 cooperates with the column 32. The transmission unit 4 is arranged on the base frame 1 and cooperates with the turntable 35. The transmission unit 4 drives the turntable 35 to rotate, and controls the slide bar 34 to slide along the slide groove 311 to approach or move away from the axis of the fixed disk 31. The turntable 35 is provided with a coupling connected with the fixed disk 31, which improves the rotation stability of the turntable 35. Before the spring is fixed, the turntable 35 is controlled to rotate by the transmission unit 4, so as to drive the slide bar 34 to slide in the inclined groove 351 and the slide groove 311 to control the column 32 to approach or move away from the axis of the fixed disk 31, so that the distance between the two relative columns 32 is greater than the outer diameter of the spring 2cm, so as to reduce the phenomenon of spring tilt or deviation.

[0032] As an embodiment further provided by the present invention, the transmission unit 4 includes a rotating rod 43, a bearing 44, and a first rotating shaft 441 and a second rotating shaft 442 respectively rotatably connected to the bearing 44, the bearing 44 is symmetrically arranged in the base frame 1, and the rotating rod 43 rotates on the base frame 1, the first rotating shaft 441 is provided with a second gear 45 matching the turntable 35, one end of the second rotating shaft 442 is sequentially provided with a first gear 41 and a worm wheel 42, the rotating rod 43 matches with the worm wheel 42, when adjusting the spacing between the columns 32, the rotating rod 43 is rotated to make the worm part 431 engage with the worm wheel 42 to rotate, thereby linking the first gear 41 to drive the second gear 45 to rotate, the combination of the worm wheel 42 and the two reduction gears further improves the accuracy of adjusting the spacing between the columns 32, and one end of the first rotating shaft 441 matches with the turntable 35.

[0033] As an embodiment further provided by the present invention, a worm portion 431 is arranged in a linear array on the rotating rod 43, and the worm portion 431 is meshed with the worm wheel 42. The number of the worm portion 431 and the worm wheel 42 is consistent with the number of the clamping units 3. A square groove is provided in a circular array at one end of the rotating rod 43 to increase the friction with the hand when the rotating rod 43 is rotated.

[0034] As an embodiment further provided by the present invention, the number of teeth of the first gear 41 is smaller than the number of teeth of the second gear 45. Since the number of teeth of the first gear 41 is smaller than the number of teeth of the second gear 45, the rotation of the second gear 45 by the first gear 41 is linked to achieve a deceleration motion, thereby more accurately adjusting the spacing between the columns 32.

[0035] As an embodiment further provided by the present invention, square grooves 321 are symmetrically provided on the column 32, and a disc 323 is slidably arranged in the square groove 321. The disc 323 cooperates with the support plate 324. When no spring is placed, the disc 323 is located at the bottom of the square groove 321 due to its own gravity. When the spring is placed, the spring is supported by the support plate 324. The support plate 324 is fixed to the disc 323 by bolts, and the length of the support plate 324 can be adjusted according to the size of the spring.

[0036] As an embodiment further provided by the present invention, a hand grip 322 is provided on the disk 323 , and the hand grip 322 improves the comfort of fitting with the hand and facilitates manual pushing of the disk 323 to slide in the square groove 321 .

[0037] As an embodiment further provided by the present invention, one end of the slide rod 34 is provided with a first slider 341 sliding in the slide groove 311, and the other end is provided with a second slider 342 sliding in the inclined groove 351. The first slider 341 and the second slider 342 increase the contact area between the slide rod 34 and the inclined groove 351 and the slide groove 311, so that the slide rod 34 slides more smoothly when the turntable 35 rotates.

[0038] As an embodiment further provided by the present invention, a support block 11 is symmetrically arranged on one side of the base frame 1, a cylinder 2 is arranged on the support block 11, and a top block 21 is arranged on the output shaft of the cylinder 2. The top block 21 cooperates with the support block 11, so that when the spring is placed on the fixed plate 31, the cylinder 2 is output to push the base frame 1 under the pressing device, thereby completing the fixing of the spring.

[0039] Working principle: First, according to the specifications of the spring, that is, the size of the outer diameter of the spring, the rotating rod 43 is rotated to make the worm part 431 engage with the worm wheel 42 to rotate, and the worm wheel 42 is linked to the first gear 41 to drive the second gear 45 to rotate, thereby controlling the rotation of the turntable 35, so that the slide bar 34 slides along the inclined groove 351 and the slide groove 311, and controls the column 32 to approach or move away from the axis of the fixed disk 31 along the slide groove 311, so that the distance relative to the column 32 is greater than the outer diameter of the spring by 2 cm, so that the spring will not tilt when placed on the support plate 324 of the column 32, and further, the cylinder 2 pushes the base frame 1 to be located under the pressing device. After the spring is fixed, the cylinder 2 retracts the output rod, and the operator can touch the hand grip 322 with his thumb and push the disc 323 to quickly take out the spring, thereby improving the efficiency of spring clamping.

[0040] The technical solution of the above utility model provides a solution that is significantly different from the prior art to address the technical problem that the prior art solution is too single. The parts not involved in the technical solution of this application are the same as the prior art or can be implemented by using the prior art and will not be described in detail.

[0041] The technical solutions in the above embodiments have clearly and completely described the contents of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
