[0023] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0024] Please refer to Figures 1-4 , a stainless steel electrical sheet coupling with good stability, including a left shaft body 1. A right shaft body 2 is installed on the outer wall of the left shaft body 1. A buckle 3 is installed on the outer wall of the left shaft body 1. A fixing bolt 4 penetrates through the interiors of the left shaft body 1 and the right shaft body 2. A fixing nut 5 is installed on the outer wall of the fixing bolt 4. The left shaft body 1 and the right shaft body 2 are snap-connected, and the left shaft body 1 and the right shaft body 2 are thread-fixed. During installation, the left shaft body 1 and the right shaft body 2 are double-fixed through the buckle 3 and the fixing bolt 4, which can effectively prevent the connection between the left shaft body 1 and the right shaft body 2 from loosening.

[0025] Please refer to Figures 1-4 , a stainless steel electrical sheet coupling with good stability. Limit blocks 6 are installed on the outer walls of the left shaft body 1 and the right shaft body 2. A connecting column 7 is installed on the outer wall of the left shaft body 1. A spring 8 is installed on the inner wall of the connecting column 7. A telescopic rod 9 is installed on the outer wall of the spring 8. A shock pad 10 is installed on the outer wall of the connecting column 7. The limit blocks 6, the left shaft body 1, and the right shaft body 2 are all arranged in an annular array, and the shock pad 10 is snap-connected to both the left shaft body 1 and the right shaft body 2. The telescopic rod 9 is movably connected to the right shaft body 2, and the telescopic rod 9 and the left shaft body 1 form a lifting structure through the spring 8. When using the device, when a collision occurs between the left shaft body 1 and the right shaft body 2, the impact force is transmitted to the telescopic rod 9 and then to the spring 8. Through the buffering of the shock pad 10 and the spring 8, the impact force can be effectively reduced. At the same time, while the limit blocks 6 can install and fix the shock pad 10, the shock pad 10 isolates the left shaft body 1 and the right shaft body 2 and the limit blocks 6 on the left shaft body 1 and the right shaft body 2, reducing the collision between the left shaft body 1 and the right shaft body 2 and extending the service life.

[0026] Please refer to Figures 1-4, a stainless - steel electric - piece coupling with good stability. On the sides of the left shaft body 1 and the right shaft body 2 away from the limit block 6, an expansion sleeve opening 11 is installed. On the outer wall of the expansion sleeve opening 11, a left clamping block 12 is installed, and on the outer wall of the expansion sleeve opening 11, a right clamping block 13 is installed. A bolt column 14 passes through the interiors of the left clamping block 12 and the right clamping block 13, and a nut 15 is installed on the outer wall of the bolt column 14. The left clamping block 12 and the right clamping block 13 are semicircular in shape, and the left clamping block 12 and the right clamping block 13 are fixedly connected by threads. The expansion sleeve opening 11 is welded to the left shaft body 1 and the right shaft body 2, and the expansion sleeve opening 11 is movably connected to the left clamping block 12 and the right clamping block 13. Before other devices are installed on the expansion sleeve opening 11, the left clamping block 12 and the right clamping block 13 are sleeved on the expansion sleeve opening 11, and the bolt column 14 and the nut 15 are rotated, so that the left clamping block 12 and the right clamping block 13 approach each other, driving the expansion sleeve opening 11 to contract inward, and other devices can be clamped and fixed on the device, preventing loosening during operation and rotation, which may lead to equipment operation failure, thereby improving the stability during installation.

[0027] Working principle: During use, first, the left clamping block 12 and the right clamping block 13 are sleeved on the expansion sleeve opening 11. Then, the device to be connected is inserted into the expansion sleeve opening 11. Then, the bolt column 14 and the nut 15 on both sides of the left clamping block 12 and the right clamping block 13 are rotated, so that the left clamping block 12 and the right clamping block 13 approach each other and clamp, and at the same time, drive the expansion sleeve opening 11 to contract inward, and the device can be stably clamped and fixed on the device. Then, the shock - absorbing pad 10 is sleeved on the connecting column 7 through the limit block 6, and the left shaft body 1 and the right shaft body 2 are isolated by the shock - absorbing pad 10 and the limit block 6. When being impacted, the telescopic rod 9 contracts under the impact force, compressing the spring 8, and the device is buffered and protected through the shock - absorbing pad 10 and the spring 8.
