The number of counterweight blocks 3 is several groups and they are arranged in an array. A through hole adapted to the outer side of the support rod 1 is opened in the middle of the counterweight block 3. The number of limit rings 4 is two groups and they are symmetrically distributed. The inside of the limit ring 4 is adapted to the outer side of the support rod 1. The number of limit grooves 6 is four groups and they are symmetrically distributed. The limit block 7 and the counterweight block 3 are fixedly connected. The limit block 7 is adapted to the limit groove 6, which is beneficial to the placement of the counterweight block 3 and avoids the counterweight block 3 from shaking during use.
[0024] Figures 1-4 As shown, the number of sliding grooves 51 is twice the number of limit rings 4. The moving hole 52 is communicated with the sliding groove 51 and extends to the middle of the limit ring 4. The number of fixing grooves 53 is several groups and they are arranged in an array.
