DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.
[0018] As Figures 1-4 shown, the present utility model includes a base 1 and a gas spring 8. A semi-circular placement groove is provided at the top of the base 1. A semi-circular rotating groove 2 is provided on the inner wall of the placement groove. A rotatable circular ring 3 is arranged in the rotating groove 2. A placement rack 5 is fixedly installed at the bottom of the inner wall of the placement groove. The horizontal and vertical parts of the placement rack 5 are located above the inner wall of the bottom end of the circular ring 3, and the circular ring 3 and the rotating groove 2 are located between the two vertical parts of the placement rack 5. A first hydraulic rod 6 is fixedly installed at the top of the horizontal and vertical part of the placement rack 5. A second hook 7 is fixedly installed at the telescopic end of the first hydraulic rod 6. A first hook 4 is fixedly installed at the top of the inner wall of the circular ring 3. Both ends of the gas spring 8 are fixedly installed with hanging rings, and the hanging rings at both ends of the gas spring 8 are respectively hung on the first hook 4 and the second hook 7.
[0019] As Figure 2 and Figure 4 shown, fixing plates 13 are fixedly installed on both sides at the upper position of the inner wall of the circular ring 3. Grooves 14 are provided at the ends of the two fixing plates 13 away from the inner wall of the circular ring 3. Third hydraulic rods 15 are fixedly installed in the two grooves 14. Clamping plates 16 are fixedly installed at the telescopic ends of the two third hydraulic rods 15. The two clamping plates 16 respectively abut against both sides of the outer wall of the gas spring 8. By controlling the third hydraulic rod 15 to push the clamping plate 16 towards the gas spring 8, the fixing and clamping of the gas spring 8 can be completed.
[0020] As Figure 2 shown, a second card slot 12 is provided at the top of the outer wall of the circular ring 3. A first card slot 11 is provided at the left end of the outer wall of the circular ring 3. An inner slot 9 is provided at the left end of the inner wall of the rotating groove 2. A second hydraulic rod 10 is fixedly installed in the inner slot 9. The telescopic end of the second hydraulic rod 10 can extend into the first card slot 11 or the second card slot 12 on the outer wall of the circular ring 3. By inserting the telescopic end of the second hydraulic rod 10 into the first card slot 11 or the second card slot 12 on the outer wall of the circular ring 3, the position of the rotated circular ring 3 can be fixed, preventing the circular ring 3 from rotating at an angle during experimental testing.
[0021] As Figure 2As shown, when the telescopic end of the second hydraulic rod 10 is located in the first card slot 11 on the outer wall of the circular ring 3, the two clamping plates 16 are in a vertical state. When the telescopic end of the second hydraulic rod 10 is located in the second card slot 12 on the outer wall of the circular ring 3, the two clamping plates 16 are in a horizontal state. When the two clamping plates 16 are in a horizontal state, they can play a role in stably supporting and clamping the gas spring 8 in the horizontal state.
[0022] As Figure 4 shown, clamping grooves are formed on the sides of the two clamping plates 16 close to the gas spring 8, and anti-slip layers are provided on the inner walls of the two clamping grooves. The clamping stability of the gas spring 8 can be greatly improved through the clamping grooves on the sides of the two clamping plates 16.
[0023] As Figure 2 shown, the distance between the tops at both ends of the rotating groove 2 is smaller than the outer diameter of the circular ring 3, which can prevent the circular ring 3 from disengaging from the rotating groove 2.
