And the hook 341 is hooked on the convex post 223 of the buffer member 20, and the buffer cylinder 21 is driven by the hook 341 to form a buffer function, and a middle section of an elastic member 40 is sleeved on the second shaft Rod 15, and the elastic member 40 has a torsion bar 41 at one end, and the torsion bar 41 is pressed against the third shaft 31, and the elastic member 40 has a torsion bar 42 at the other end, and the torsion bar The moving rod 42 is pressed against the first shaft 14, and the torsion force of the movable seat 30 relative to the seat body 10 is formed by the torque of the elastic member 40, and the sliding seat 23 is recessed with a dodging portion 234. The avoiding portion 234 is used to avoid the twisting lever 42 of the elastic member 40.

For the combination of the structures, please continue to view from FIG. 1 to FIG. 5. The buffer member 20 is passed through the accommodating hole 231 of the slide seat 23 with the buffer cylinder 21, and the connecting member 22 The connecting piece 221 is fixed to the sliding seat 23, and one end of the actuating rod 211 is fixed to the connecting member 22, and the other end can move the buffer cylinder 21 to slide to the receiving hole 231, and the buffer 20 is placed in the seat. Between the two side plates 12 of the body 10, the buffer cylinder 21 is pressed against the bottom plate 11 and pushed inward along the bottom plate 11, so that the limiting groove 233 of the slide seat 23 receives the pillar of the base body 10. 13. The movable seat 30 passes one end of the rocker arm 33 with the third shaft 31, and one end of the link arm 34 with the fourth shaft 32, and the other end of the rocker arm 33 and the The elastic member 40 is disposed between the two side plates 12 at the same time, and the second shaft 15 passes through the side plate 12, the rocker arm 33 and the elastic member 40 at the same time, and the torsion bar 41 of the elastic member 40 abuts against the fourth plate. The shaft 32, and the other end of the link arm 34 is disposed between the two side plates 12, so that the first shaft 14 passes through the side plate 12 and the link arm 34 to form a pivot connection, and the first shaft 14 resist the twist Move the lever 42 and let the hook 341 of the link arm 34 be hooked on the protruding post 223 of the buffer member 20. It is worth noting that the buffer member 20 will be limited to the pillar 13, the bottom plate 11 and the first shaft 14. And the second shaft 15, thereby having the effect of easy assembly.

For actual use, please refer to Figures 5, 6, and 7 and Figure 2. The base 10 is used as the fixed end, and the movable base 30 is the movable end, and the movable base 30 can be operated. The swinging position has a collapsed position and an expanded position. When the retracted position is moved to the expanded position, the movable seat 30 is pushed outward, so that the fourth shaft 32 pushes the torsion bar 41 of the elastic member 40, and the The movable seat 30 links the rocker arm 33 and the linked arm 34 to form a swing. At this moment, the hook 341 of the linked arm 34 will push the protruding post 223 to move away from the elastic member 40, and the protruding post 223 also links the slide seat. 23 is synchronized with the connecting member 22, and when the hook 341 pushes the protruding column 223, a downward force component is also generated on the protruding column 223, and the buffer member 20 is pressed by the buffer cylinder 21. Since the buffer cylinder 21 can be fixed to the bottom plate 11, the actuating rod 211 is driven by the connecting member 22 in a stretched state, and the buffer cylinder 21 is in a state of no resistance in this state. This operation is actuated to the expanded position, and when it is actuated to the collapsed position in the expanded position, the movable seat 30 is pushed inwardly and externally, and cooperates with the elastic force of the elastic member 40 to form an automatic collapse. During the collapse process, When the hook 341 of the link arm 34 is pulled back to the protrusion 223 of the buffer member 20, the connecting member 22 pushes the actuating rod 211 into the buffer cylinder 21, thereby forming a collapse through the internal resistance of the buffer cylinder 21. When the hook 341 is pulled back to the protruding post 223, it will generate a lower pressing force for the protruding post 223 than that of the protruding post 223, so that the buffer member 20 can be stably fixed to the protruding post 223. The base plate 11 is used to achieve the function of the hinge.

By virtue of the structure of the above specific embodiment, the following benefits can be obtained: the cushioning member 20 is directly slid on the bottom plate 11 of the base body 10, and the limiting groove 233 of the cushioning member 20 accommodates the pillar of the base body 10 The body 13 is further provided with the second shaft 15 for connecting the side plate 12, the elastic member 40 and the swing arm 33 at the end of the movable seat 30, and the first shaft 14 is also connected through the side plate 12 and the linkage. The arm 34 allows the hook claw 341 of the linkage arm 34 to be hooked on the protruding post 223 of the buffer member 20, that is, the buffer member can be formed through the pillar 13, the bottom plate 11, the first shaft 14 and the second shaft 15. The position of 20 is fixed, which has the effect of quickly completing its assembly. The simplified structure and simple assembly steps enable it to be assembled automatically, which can significantly reduce material and labor costs before the same function, thereby increasing its Practicality.

To sum up, the present invention has indeed achieved a breakthrough structural design, with improved content of the invention, and at the same time, it can achieve industrial applicability and progress, and the present invention is not seen in any publications, and it is also novel.
