The slide bars 61 are slidably arranged through the hollow rotating rod 6. A brake pad 62 is provided at one end of the slide bar 61 located outside the hollow rotating rod 6.

[0025] When the position of the tower crane ear seat 4 and the slide seat 2 needs to be adjusted, the hydraulic pump station 51 controls the corresponding hydraulic cylinder 63 to work, and the hydraulic cylinder 63 extends, driving the slide rod 61 to move, so that the brake pad 62 is closely abutted against the inner wall of the screw rod 8. At this time, the corresponding screw rod 8 is fixedly connected to the hollow rotating rod 6, and the motor 7 drives the hollow rotating rod 6 to rotate, which can drive the corresponding screw rod 8 to rotate. The screw rod 8 fixedly connected to the hollow rotating rod 6 remains stationary while the hollow rotating rod 6 rotates.
