The ball center of the ball joint end portion is as if locked on the specific extension line of the axis of the adjusting threaded rod body by an invisible coordinate system. This accurate corresponding arrangement enables the force to be transmitted to the ball joint end portion along the axial direction of the adjusting threaded rod body in the most optimized path during mechanical operation.

[0012] Preferably, the vertical cross-section of the adjusting hexagonal drive slot is designed to be hexagonal.

[0013] By adopting the technical scheme, when the operator rotates the adjusting hexagonal drive slot using a hexagonal wrench, strong friction and biting force can be generated between the hexagonal cross-section and the inner hole of the wrench due to the perfect fit between them. This enables the torque to be uniformly and efficiently transmitted during the adjustment process, avoiding adjustment errors caused by slipping, misalignment, etc. Compared with other shapes of drive slots, the hexagonal design greatly improves the accuracy and stability of the adjustment.

[0014] Preferably, the inner wall of the adjusting hexagonal drive slot near the ball head connecting end is designed to be inclined.

[0015] With the above technical scheme, when the adjusting hexagonal drive slot is operated by using the matched tool, the inclined inner wall can guide the force to be more concentrated on the specific stress point of the connected device, so that more efficient and accurate adjustment is realized.

[0016] Compared with the prior art, the balance car ball head adjusting bolt has the advantages that:

[0017] 1. The ball head connecting end and the adjusting hexagonal drive slot are arranged, in operation, the ball head of the ball head adjusting bolt is placed into the corresponding ball-shaped groove or joint part of the part to be connected or adjusted, so that the ball head can freely move in the groove and tightly cooperate, the ball head can be rotated at different angles, the adjusting hexagonal drive slot at the tail of the device is used to drive the adjusting threaded rod body to rotate, and finally the height is adjusted through the movement of the threads on the outer surface of the adjusting threaded rod body.
