[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example:

[0031] Reference Figure 1-Figure 3 As shown, this utility model discloses a folding gas spring, including a gas spring body 1. A telescopic assembly 2 is provided on the gas spring body 1, and the telescopic assembly 2 includes two placement blocks 21. The vertical cross-section of the side of the placement block 21 that contacts the gas spring body 1 is arc-shaped, and the arc-shaped surface of the placement block 21 is in contact with the surface of the gas spring body 1.

[0032] Each of the two placement blocks 21 has a first through hole 22 on one side. The two placement blocks 21 are symmetrically arranged on the outer circumferential surface of the gas spring body 1, and the placement blocks 21 are slidably connected to the gas spring body 1.

[0033] The gas spring body 1 and the two placement blocks 21 are jointly provided with a drive assembly 3, which drives the two placement blocks 21 to move simultaneously.

[0034] The drive assembly 3 includes two guide rods 31, both of which are fixedly installed in the corresponding first through hole 22. Connecting blocks 32 are provided on both sides of the gas spring body 1. The connecting blocks 32 are located in the corresponding first through hole 22. The guide rods 31 pass through the corresponding connecting blocks 32 and are slidably connected to the corresponding connecting blocks 32.

[0035] A push ring 33 is slidably sleeved on the outer circumference of the gas spring body 1, and the push ring 33 is fixed to two placement blocks 21. A fixing component 4 is provided on the push ring 33, and the fixing component 4 fixes the position of the push ring 33.

[0036] The fixing component 4 includes several fixing blocks 41, which are evenly fixed on the side of the push ring 33 away from the placement block 21. Each fixing block 41 is provided with a first screw 42, which is threadedly connected to the corresponding fixing block 41. The bottom end of the first screw 42 is provided with a pressure plate 43, which is rotatably connected to the corresponding first screw 42.

[0037] The outer circumferential surface of the gas spring body 1 is evenly provided with several first placement grooves 5. The positions of the first placement grooves 5 correspond to the positions of the corresponding pressure plates 43, and the side of the first placement groove 5 facing the corresponding pressure plate 43 is a flat surface. As the pressure plate 43 moves, the pressure plate 43 moves into the interior of the first placement groove 5 and comes into contact with the flat surface of the corresponding first placement groove 5. Anti-slip textures are machined on the flat surface of each pressure plate 43 and each first placement groove 5.

[0038] A reversing assembly 6 is provided between the tail ends of the two placement blocks 21. The reversing assembly 6 includes a first rotating rod 61, which is rotatably connected to both placement blocks 21. A rotating plate 62 is fixedly sleeved on the outer circumference of the first rotating rod 61. A fixing seat 63 is provided at one end of the rotating plate 62, and the fixing seat 63 is located on the outside of the two placement blocks 21. A diamond-shaped groove 64 is provided on one side of the rotating plate 62, and one end of the diamond-shaped groove 64 passes through one of the placement blocks 21. A diamond-shaped post 65 is provided at the diamond-shaped groove 64, and a second screw 651 is provided at one end of the diamond-shaped post 65. The second screw 651 is located on the outside of the corresponding placement block 21, and a nut 66 is threadedly connected to the outer circumference of the second screw 651. The nut 66 is in contact with one side of the corresponding placement block 21.

[0039] The implementation principle of the above embodiments is as follows:

[0040] The operator pushes the push ring 33, which simultaneously drives the two placement blocks 21 to move along the straight line of the guide rod 31. When the push ring 33 moves to the appropriate position, the operator uses a tool to rotate the first screw 42. As the first screw 42 rotates, it moves in the direction of the corresponding first placement groove 5. After the pressure plate 43 moves into the first placement groove 5 and fits tightly against the bottom plane of the inner wall of the first placement groove 5, the operator stops rotating the tool.

[0041] Following the above method, several pressure plates 43 on the push ring 33 are all fitted into the plane in the first placement groove 5.

[0042] Next, the operator rotates the first rotating rod 61, which in turn changes the orientation of the rotating plate 62 and the fixed seat 63. Once the fixed seat 63 has rotated to the appropriate position...

[0043] The operator inserts the rhomboid prism 65 into the rhomboid groove 64. It should be noted that one of the placement blocks 21 has a through hole on one side. No matter how the first rotating rod 61 rotates, the complete rhomboid groove 64 can be seen through the through hole on this placement block 21. This through hole is smaller than the vertical cross-sectional area of ​​the first rotating rod 61, ensuring that the first rotating rod 61 and this placement block 21 always remain in contact.

[0044] Then, by rotating the nut 66, the nut 66 is made to fit against the surface of the corresponding placement block 21, thereby fixing the position of the first rotating rod 61.

[0045] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
