[0037] The sleeve 4 is provided with a locking piece 5 for locking between the sleeve 4 and the telescopic rod 1, the locking piece 5 is composed of a bolt 632 and a knob, the bolt 632 is rotated by rotating the knob, and then the bolt 632 is driven to abut against the telescopic rod 1 to fix the sleeve 4; two sleeves 4 are installed with a folding support 6 for connecting two telescopic rods 1 into one.

[0038] Please refer to Figure 4 The folding support 6 comprises a connecting rod A61 and a connecting rod B62 respectively hingedly connected with two sleeves 4, the connecting rod B62 and the connecting rod A61 close to the end are provided with a hinge assembly 63 for hingedly connecting the connecting rod A61 and the connecting rod B62; in the unused state, the connecting rod A61 is accommodated in the connecting rod B62 downward, when the folding support 6 is unfolded upward, the connecting rod A61 is relatively rotated with the connecting rod B62 through the hinge assembly 63, and is moved out of the connecting rod B62, and pushes two telescopic rods 1 away from each other to the two sides, and then unfolds the combined insulating support of the utility model, and the distance between the two telescopic rods 1 can be controlled when the folding support 6 is unfolded to push the two telescopic rods 1 away from each other, so as to adapt to the length of the insulating rod to be clamped.

[0039] Please refer to Figure 4The connecting rod A61 comprises a support A611 fixedly connected to the outer circumferential surface of one of the sleeves 4, a connecting head A612 hingedly connected to the support A611, and a rod body A613 fixedly connected to the side of the connecting head A612 away from the support A611;
