[0038] The capacitor clamping assembly comprises an opening and closing wheel 232 and three righting arms 233. The opening and closing wheel 232 is rotatably sleeved on the outer periphery of the capacitor support shaft 231 and located above the support bearing seat 2313. The opening and closing wheel 232 is partially accommodated in the recessed groove at the top end of the support bearing seat 2313, and the support bearing seat 2313 partially protrudes from the outer wall of the opening and closing wheel 232. In the embodiment, the inner hole 2325 of the opening and closing wheel 232 is provided with an opening and closing wheel bearing 2326, which is sleeved on the outer periphery of the capacitor support shaft 231 to provide support for the rotation of the opening and closing wheel 232. The number of opening and closing wheel bearings 2326 can be set according to actual conditions. The three righting arms 233 are located above the opening and closing wheel 232 and are spaced around the capacitor support shaft 231. The opening and closing wheel 232 is circumferentially spaced apart and provided with three mounting shafts 23221 corresponding to the three righting arms 233, respectively. In the embodiment, the outer wall of the opening and closing wheel 232 is circumferentially spaced apart and provided with three protrusions 2322, and the top end of each of the three protrusions 2322 is provided with one of the three mounting shafts 23221. The righting arm 233 is rotatably sleeved on the outer periphery of the corresponding mounting shaft 23221, and the first end of the righting arm 233 is located on the side opposite to the corresponding mounting shaft 23221 in the counterclockwise direction, and the second end of the righting arm 233 is located on the side opposite to the corresponding mounting shaft 23221 in the clockwise direction. The first end of the three righting arms 233 is close to the capacitor support shaft 231 and is provided with a correction wheel 2332, and the correction wheel 2332 is located above the capacitor support shaft 231. The second end of the righting arm 233 extends away from the capacitor support shaft 231 and is provided with a mounting rod, and the distal end of the mounting rod is provided with a connecting wheel 2333.

The second end of the three righting arms 233 is located above the three protrusions 23131, respectively. The connecting wheel 2333 of the righting arm 233 is matched with the corresponding mounting groove 23132.When the opening and closing wheel 232 rotates in the counterclockwise direction, under the action of the mounting shaft 23221, the first end of the three righting arms 233 can be moved away from the capacitor support shaft 231, and in turn, the correction wheel 2332 of the three righting arms 233 can be moved away from the capacitor support shaft 231, so that the capacitor 200 on the capacitor support shaft 231 can be loosened by the correction wheel 2332 of the three righting arms 233. When the opening and closing wheel 232 rotates in the clockwise direction, under the action of the mounting shaft 23221, the first end of the three righting arms 233 can be moved towards the capacitor support shaft 231, and in turn, the correction wheel 2332 of the three righting arms 233 can be moved towards the capacitor support shaft 231, so that the capacitor 200 on the capacitor support shaft 231 can be clamped by the correction wheel 2332 of the three righting arms 233. By clamping the capacitor 200 with the correction wheel 2332, the correction wheel 2332 forms a rolling contact with the capacitor 200 when clamping, which can prevent the capacitor 200 from being scratched. By using three righting arms 233, when the axis of the capacitor 200 is not collinear with the axis of the capacitor support shaft 231, i.e., the capacitor 200 is misaligned, the capacitor 200 can be pushed towards the axis of the capacitor support shaft 231 during the process of the first ends of the three righting arms 233 moving towards each other, which can correct the position of the capacitor 200 to ensure that the axis of the capacitor 200 is collinear with the axis of the capacitor support shaft 231, i.e., the capacitor 200 is located at the center of the capacitor support shaft 231. By using three righting arms 233 and an opening and closing wheel 232, the distance that the first ends of the three righting arms 233 move towards or away from the capacitor support shaft 231 can be adjusted by adjusting the angle of rotation of the opening and closing wheel 232, which can adapt to capacitors 200 of different outer diameter sizes and height sizes, has good versatility, and has a wide range of applications. In other embodiments, the number of righting arms 233 can also be other, such as four, five, six, etc., which can be set according to actual conditions.

One end of the turntable elastic element 234 is connected with the swing arm 2321, and the other end of the turntable elastic element 234 is connected with the top end of the support bearing seat 2313. When the capacitive support shaft 231 is loosened from the capacitive support 200 through the three righting arms 232, the turntable elastic element 234 is stretched at this time. When the pushing wheel 253 separates from the inclined surface 23211 of the swing arm 2321, the opening and closing wheel 232 is driven to rotate in the clockwise direction to the initial position by the swing arm 2321 under the reset action of the turntable elastic element 234.
