Under the action of gravity, the locking rod slides into the lock groove along the inclined groove and engages with the inner bottom of the lock groove.

10. A method for using a stable supporting well tower, using the stable supporting well tower according to claim 9, characterized in that: The following steps are involved: Step 1: When unloading materials, the traction device is started in the forward direction, the traction device drives the traction cable (32) to move, the traction cable (32) drives the sky wheel (31) to rotate, the traction cable (32) drives the hook (33) to move upward, the hook (33) pulls the material transport bin (5) to move upward, when the material transport bin (5) moves into the ring section of the lasso (414), the motor (411) is started, the motor (411) drives the rotating shaft (412) to rotate, and the rotating shaft (412) is rotated. 12) drives the connecting block 1 (413) to rotate, the connecting block 1 (413) drives the lasso (414) to rotate, the lasso (414) drives the connecting block 2 (416) and the rotating shaft 2 (417) to rotate. At this time, since the straight end of the lasso (414) is fixed, when the lasso (414) rotates, a pulling force is generated on the lasso (414) and the ring-shaped section of the lasso (414) is reduced and clamped against the outer wall of the material transport bin (5), and at this time, the spring (415) sends elastic deformation; Step 2: reversely start the traction device so that the pulling force of the hook (33) on the material transport bin (5) gradually decreases, and at this time the material transport bin (5) is turned over by the lasso (414), and the material transport bin (5) is in conflict with the upper end of the lower hopper (42), and the ore in the material transport bin (5) is dumped out along the lower hopper (42) to complete the unloading; Step 3, starting the traction device in the forward direction, and at the same time starting the motor (411) to reset, the material transport bin (5) returns to the normal position, and at the same time the lasso (414) is reset under the elastic force of the spring (415), so that the lasso (414) is separated from the outer wall of the material transport bin (5); Step 4: When the lower tower body (13) is lifted to a suitable height, the hydraulic cylinder (21) is started, and the hydraulic cylinder (21) pushes the middle tower body (12) to lift, and the lifting of the middle tower body (12) drives the pulley (23) to lift, and the pulley (23) and the lifting cable (22) drive, and the lifting cable (22) pulls the lower tower body (13) to lift; Step 5: During the lifting process of the lower tower body (13), the lower tower body (13) drives the ear plate (63) and the locking rod (65) to lift, and the locking rod (65) slides in contact with the outer wall of the latch (61) and the inner top of the locking groove (62) until the lower tower body (13) reaches a specified height. Under the action of gravity, the locking rod (65) slides into the locking groove (62) along the inclined groove (64) and contacts and engages with the inner bottom of the locking groove (62).
