The lower surface of the movable seat 2 is provided with a guide rod 3, and the two ends of the guide rod 3 are respectively connected to the movable seat 2 by fixing. A plurality of guide sleeves 4 are respectively installed on the guide rod 3, and the guide sleeves 4 are respectively fixedly connected to the fixed seat 1. The upper surface of the fixed seat 1 is fixedly connected with an intermediate clamping block 5, and both sides of the intermediate clamping block 5 are respectively provided with movable clamping plates 6, and the movable clamping plates 6 are respectively fixedly connected with inner guide rods 7, and inner guide sleeves 8 are installed on the inner guide rods 7. Two spring seats 9 are fixedly installed below the movable seat 2, and the intermediate clamping block 5 is located between the two spring seats 9. The spring seat 9 corresponds to the movable clamping plate 6. A spring is provided between the spring seat 9 and the corresponding movable clamping plate 6, and the inner guide sleeves 8 are respectively fixedly connected to the corresponding spring seats 9. The inner guide rod 7 is parallel to the guide rod 3. The spraying robot is fixed on the movable seat 2. The buffer base moves with the spraying robot. When the buffer base moves from motion to stillness, the spraying robot continues to move with the movable base 2 due to inertia, and the spring is used to generate buffer. The spraying robot swings back and forth with the movable base 2 for a period of time until it stops completely. In this way, the spraying robot will not trigger the internal protection system due to violent collision.

[0017] Furthermore, a fixing groove 10 is provided on the spring seat 9 , and a movable groove 11 is provided on the movable clamping plate 6 . One end of a spring (not shown in the drawings) is located in the fixing groove 10 , and the other end is located in the movable groove 11 .

[0019] Furthermore, the spring seat 9 is provided with a threaded hole connected to the fixing groove 10, the threaded hole is threadedly connected to the adjusting screw 12, and the spring is clamped between the adjusting screw 12 and the movable clamping plate 6. By rotating the adjusting screw 12, the spring can be compressed or loosened, thereby adjusting the buffering effect.

[0020] Furthermore, there are two inner guide rods 7 connected to the movable splint 6 , and the spring is located between the two inner guide rods 7 .

[0021] Further, the number of the guide rods 3 is two, and the two guide rods 3 are arranged in parallel. The two ends of the guide rods 3 are respectively fixedly connected to the movable seat 2 through the fixing blocks. The fixing blocks include an upper fixing block 13 and a lower fixing block 14. The upper fixing block 13 is provided with an upper circular groove 15, and the lower fixing block 14 is provided with a lower circular groove. The upper circular groove 15 and the lower circular groove are combined to form a circular clamping groove for clamping the guide rod 3. The upper fixing block 13 and the lower fixing block 14 are respectively provided with a plurality of through holes 16, and bolts are arranged in the through holes 16. The fixing blocks are connected to the movable seat 2 through the bolts, and the spring seat 9, the movable clamping plate 6 and the middle clamping block 5 are all located between the two guide rods 3. The two guide rods 3 guide the movement of the movable seat 2, so that the movement of the movable seat 2 relative to the fixed seat 1 is more stable.

[0022] Furthermore, the movable seat 2 is provided with a plurality of adjustment openings 17 respectively facing the adjustment screw 12. The adjustment screw 12 can be rotated through the adjustment openings 17 using a tool such as a wrench, thereby adjusting the elastic force of the spring and adjusting the buffering effect.
