[0007] As a further technical scheme of the utility model, the cantilever is intermittently freely rotated by 90°, and the maximum rotation angle is 180°.

[0008] As a further technical scheme of the utility model, the pressing plate is made of TPU injection molding material, and the size of the pressing plate is matched with the battery pack.

[0009] As a further technical scheme of the utility model, the shell edge is rounded, and the pull ring is an alloy metal ring.

[0010] Compared with the prior art, the battery pack circulating rack left-handed bolt capable of conveniently adjusting the cantilever position has the advantages that the cantilever position can be adjusted without a complicated fastening structure.

[0011] The position and angle of the cantilever are adjusted by rotating the rotating part at the top, so that the object placed below the cantilever is fixed, and the specific method is that when the rotating part is tightened, the cantilever can firmly press the object; when the pull ring is pulled out, the spring will lift the pressing block, and the spring pressing block can be relaxed, the position of the cantilever can be adjusted, the base has three studs distributed in a 90° triangle, the range of movement of the cantilever is limited, the cantilever can be intermittently rotated by 90°, the maximum rotation angle is 180°, the cantilever can be locked by being pressed downward, the cantilever position can be conveniently adjusted without a complicated fastening structure.
