Four support legs 22 are fixedly installed on the bottom side of the bottom plate 1. A second motor 14 is fixedly installed on the bottom side of the bottom plate 1. The output end of the second motor 14 rotates through the bottom plate 1 and is fixedly sleeved with a gear 15. A first toothed plate 16 and a second toothed plate 17 are respectively arranged on the outer side of the gear 15. The first toothed plate 16 and the second toothed plate 17 are symmetrically arranged and both are engaged with the gear 15. Baffles 20 are fixedly installed on the top sides of the first toothed plate 16 and the second toothed plate 17. Observation windows 21 are opened on both baffles 20.

A pulling assembly is arranged on the top sides of the two mounting brackets 2. By running the second motor 14 to drive the gear 15 to rotate counterclockwise, and because both the first toothed plate 16 and the second toothed plate 17 are engaged with the gear 15, when the gear 15 rotates counterclockwise, it will drive the second toothed plate 17 to move towards the left, and the first toothed plate 16 will move towards the right, so that the first toothed plate 16 and the second toothed plate 17 approach each other, and then the two baffles 20 move synchronously. When the two baffles 20 respectively move to both sides of the two mounting brackets 2, it can play a protective role during the tensile test, avoiding the spring being broken during the test and causing harm to the personnel beside. And through the observation windows 21 opened on both baffles 20, personnel can observe the situation of the clock spring through the observation windows 21.

[0022] Specifically, the guide assembly includes two tracks 18 fixedly installed on the inner wall of the bottom side of the bottom plate 1.

The sides of the two guide blocks 19 close to each other are fixedly connected to the sides of the first toothed plate 16 and the second toothed plate 17 away from each other. By arranging the two guide blocks 19, when the gear 15 drives the first toothed plate 16 and the second toothed plate 17 to approach or move away from each other, the two guide blocks 19 will always slide in the guide grooves opened on the two tracks 18, which can limit and guide the first toothed plate 16 and the second toothed plate 17 during movement, avoiding the situation of deviation during movement.

[0023] Specifically, mounting plates 11 are fixedly installed on both the bottom side of the pressure sensor 10 and the top side of the bottom plate 1.

The two mounting plates 11 are arranged on the same vertical horizontal line. By providing two groups of clamping components, before the test, the two ends of the clock spring are respectively placed between the two groups of clamping plates 13, and then the two groups of cylinders 12 are synchronously started so that the two groups of clamping plates 13 complete the clamping of the two ends of the clock spring.

[0024] Specifically, the pulling component includes a top plate 5 fixedly installed on the top sides of the two mounting frames 2. The top plate 5 is provided with a through hole. Two fixing plates 6 are fixedly installed on the top side of the top plate 5. A first motor 7 is fixedly installed on the outer side of one fixing plate 6.

By running the first motor 7 to drive the two winding wheels 8 to rotate clockwise, the two winding wheels 8 respectively wind the two ropes 9. During the winding process, the two ropes 9 can pull the connecting plate 4 to move up synchronously. And by providing two ropes 9, the stability of the connecting plate 4 during rising can be ensured, avoiding the situation of one side being higher and the other side being lower. During the rising process, the pressure sensor 10 can detect and record the tensile force of the spring in real time.

[0025] Specifically, sliding grooves are respectively formed on the sides of the two mounting frames 2 close to each other. Two sliders 3 are slidably installed in the two sliding grooves. The sides of the two sliders 3 close to each other are fixedly connected to the side of the connecting plate 4 away from each other. By providing the two sliders 3, during the process of the two ropes 9 driving the connecting plate 4 to move up, the two sliders 3 will move up synchronously with the connecting plate 4, which can play a guiding role during the up and down movement of the connecting plate 4, avoiding the situation of deviation resulting in inaccurate detection data.

[0026] Specifically, two through sliding holes are formed on the top side of the bottom plate 1, and are respectively located above the first toothed plate 16 and the second toothed plate 17. The two baffles 20 respectively slide in the two through sliding holes. By providing the two through sliding holes, when the two baffles 20 move, a guiding role and a supporting role can be provided.

[0027] The electrical components appearing in this text are all connected to the external main controller and 220V mains, and the main controller can be a conventional known device such as a computer for control.

[0028] During use: When a tensile pressure test needs to be performed on the clock spring, the two ends of the clock spring are respectively placed between two sets of clamping plates 13. Subsequently, two sets of cylinders 12 are synchronously started so that the two sets of clamping plates 13 complete the clamping of the two ends of the clock spring. After clamping, the second motor 14 is started to drive the gear 15 to rotate counterclockwise. Since both the first toothed plate 16 and the second toothed plate 17 are engaged with the gear 15, when the gear 15 rotates counterclockwise, it will drive the second toothed plate 17 to move towards the left, and the first toothed plate 16 will move towards the right, so that the first toothed plate 16 and the second toothed plate 17 approach each other, and then the two baffles 20 move synchronously. When the two baffles 20 respectively move to both sides of the two mounting brackets 2, they can play a protective role during the tensile test, preventing the spring from being broken during the test and causing harm to the personnel beside. And through the observation windows 21 opened on both baffles 20, personnel can observe the situation of the clock spring through the observation windows 21. By starting the first motor 7 to drive the two reel wheels 8 to rotate clockwise, the two reel wheels 8 respectively wind up the two ropes 9. During the winding process, the two ropes 9 can pull the connecting plate 4 to move upward synchronously. And the two ropes 9 are provided to ensure the stability of the connecting plate 4 when rising, avoiding the situation of one side being higher and the other side being lower. During the rising process, the pressure sensor 10 can detect and record the tensile force of the spring in real time. After the test is completed, the second motor 14 is driven to drive the gear 15 to rotate clockwise, so that the first toothed plate 16 and the second toothed plate 17 drive the two baffles 20 to move away from each other. Subsequently, two sets of cylinders 12 are synchronously started, and the two sets of clamping plates 13 can stop clamping the two ends of the spring. Then, another sampled spring can be detected.
