[0029] When in use, the connecting block 12 is fixed to the electric vehicle by bolts, and the connecting block 12 , the clamping seat 11 , and the bearing 10 can support the second column 4 , thereby improving the stability of the second column 4 and the first column 1 .

[0030] For ease of disassembly, exemplary, such as Figure 3 As shown, the two sides of the clamp seat 11 are welded and fixed with limit blocks 15, the two sides of the clamp seat 11 are provided with connecting rods 17, and the two limit blocks 15 are provided with through holes adapted to the connecting rods 17;

[0031] The facing ends of the two connecting rods 17 are both welded and fixed with plug blocks 16 , and the two connecting rods 17 are both sleeved with springs 18 . Slots adapted to the plug blocks 16 are provided on both sides of the clamping seat 11 and the connecting block 12 .

[0032] When in use, after fixing the connecting block 12 with bolts, if the clamp seat 11 and the second column 4 need to be removed for maintenance, just pull the two connecting rods 17. The two connecting rods 17 drive the two plug blocks 16 to move away from the connecting block 12, and the ends of the two plug blocks 16 will be disengaged from the connecting block 12, making it convenient to remove the clamp seat 11, the first column 1, and the second column 4 for maintenance.

[0033] In order to prevent the connecting rod 17 from separating from the limiting block 15, for example, Figure 3 As shown, the ends of the two connecting rods 17 away from the clamping seat 11 are both welded and fixed with a first stopper 19 , and the two connecting rods 17 are symmetrically arranged with respect to the clamping seat 11 .

[0034] The two adjusting bolts 6 are arranged parallel to each other.

[0039] Loosen the nuts 5 on the two adjusting bolts 6, pull out the sleeve 8, and tighten the nuts 5, so that the distance between the sleeve 8 and the second column 4 can be adjusted as needed, thereby adjusting the overall length of the first column 1 and the second column 4, thereby increasing the scope of application. The sleeve 8 can protect the first column 1, the second column 4 and the second ferrule 3 can protect the lower half of the first column 1, and the second ferrule 3 can protect the second column 4;

[0040] If the clamping seat 11, the first column 1, and the second column 4 need to be removed for maintenance, only the two connecting rods 17 need to be pulled. The two connecting rods 17 drive the two plug-in blocks 16 to move away from the connecting block 12, and the ends of the two plug-in blocks 16 are disengaged from the connecting block 12, making it convenient to remove the clamping seat 11, the first column 1, and the second column 4 for maintenance.
