The hole of polygon is offered on body, is engaged on the outside of the second tube body with the polygonal hole on the first body, is opened up on the outside of the first tube body
There is a threaded hole, the second tube body and the first tube body correspondence position are provided in the axial direction with some grooves for being used to be inserted into bolt head, and first
Tube body neutralizes the second tube body and is bolted relative position, and carrying out cooperation using polygon can effectively prevent from removing nut
During telescopic rod is relaxed because rotating the present apparatus phenomenon, it is and easy for operation.
Further, the groove opened up on the second tube body is uniformly distributed, the distance between adjacent two groove for 5cm~
10cm, operator can adjust different length as needed and be operated.
Further, hand handle is provided at both ends with non-slip mat, effectively prevents from skidding between human hand and handle in disassembly process
Phenomenon, improves removal efficiency.
