但是， 上述结构的极间连接装置， 存在以下问题： 1、 连接杆是定长件， 边极固定架与 中间极固定架之间的距离， 始终与两者在调节杆上的相对位置对应， 即通过调整两个固定架 在调节杆上的位置实现两者的距离调整， 在调整时， 必须松开或拧紧两个固定架对应的两个 调节螺母， 操作比较麻烦； 2、 ώ于中间极柱是固定不动的， 与中间极柱对应的中间极固定 架在调节杆上的位置调整不能过大， 否则会使中间极柱两侧的两个极间连接装置发生干涉， 这就要求连接杆位于边极固定架一侧的螺纹段较长， 使得边极固定架一侧的调节螺母需要旋 入很长的距离， 调整不方便且费时， 工作效率低； 3、 在运输过程中， 边极柱与中间极柱要 保持平行， 这就要求缩小边极固定架与中间极固定架的距离， 但是缩小后， 连接杆位于边极 固定架的一端伸出边极固定架过长， 容易发生磕碰； 4、 边极销轴和中间极销轴上的供调节 杆穿过的孔必须保证调节杆能够滑动， 若调节螺母没有拧紧， 在运输过程中， 调节杆发生轴 向运动， 使边极柱发生晃动。
发明内容 However, the inter-electrode connection device of the above structure has the following problems: 1. The connecting rod is a fixed length piece, and the distance between the side pole fixing frame and the intermediate pole fixing frame always corresponds to the relative position of the two on the adjusting rod. That is, the distance between the two fixing brackets can be adjusted by adjusting the position of the two fixing brackets on the adjusting rod. During the adjustment, the two adjusting nuts corresponding to the two fixing brackets must be loosened or tightened, which is troublesome to operate; The column is fixed, and the position of the intermediate pole holder corresponding to the middle pole on the adjusting rod should not be adjusted too much, otherwise the two pole connecting devices on both sides of the middle pole will interfere, which requires connection. The threaded section of the rod on one side of the side pole holder is long, so that the adjusting nut on one side of the side pole holder needs to be screwed into a long distance, the adjustment is inconvenient and time-consuming, and the work efficiency is low; 3. During transportation, the side The pole and the middle pole are kept parallel, which requires the distance between the pole holder and the intermediate pole holder to be reduced, but after the reduction, the connecting rod is located at one end of the edge holder The fixing frame is too long and is prone to bumping. 4. The hole on the side pin and the middle pin shaft for the adjusting rod to pass through must ensure that the adjusting rod can slide. If the adjusting nut is not tightened, the adjusting rod occurs during transportation. The axial movement causes the edge pole to sway. Summary of the invention
