[0022] By the above design, when using the device, first fix the lower section column 1 at the lower position in the elevator shaft, and ensure its perpendicularity within the standard range by traditional effective means. After the lower section column 1 is installed, the positioning sleeve 3 is sleeved on the upper end of the lower section column 1, and then the upper section column 2 is inserted from the top of the positioning sleeve 3. At this time, the lower section column 1 and the upper section column 2 are connected in place under the sleeve of the positioning sleeve 3. Then, adjust the positions of the first insertion hole 6 on both sides of the positioning sleeve 3 and the second insertion hole 7 on both sides of the lower section column 1 and the upper section column 2. Then, insert the two wedge-shaped rods 5 on the left side of the side plate 4 into the first insertion hole 6 on the positioning sleeve 3 and pass through the second insertion hole 7 on the lower section column 1 and the upper section column 2. Finally, the left end of the wedge-shaped rod 5 penetrates the lower section column 1, the upper section column 2 and the positioning sleeve 3 and is located on the left side of the positioning sleeve 3. At this time, since the left end of the wedge-shaped rod 5 and the inner end of the lock block 9 are both inclined in structure, the wedge-shaped rod 5 will first abut against the lock block 9 to compress the first spring and move aside until the side plate 4 is attached to the right wall of the positioning sleeve 3. At this time, the wedge-shaped rod 5 reaches the maximum insertion distance, so that the lock block 9 encounters the lock groove 10 on the wedge-shaped rod 5 and is clamped into the lock groove 10 under the rebound of the first spring, thereby firmly locking the wedge-shaped rod 5. At this time, the lower section column 1 and the upper section column 2 are firmly limited and sleeved by the positioning sleeve 3. This design facilitates quick and easy sleeving and fixing without the need for installation workers to use traditional tools for installation. On the other hand, due to the limited sleeving of the positioning sleeve 3, only the lowermost lower section column 1 needs to be adjusted to meet the requirements of perpendicularity, and the uppermost upper section column 2 can be automatically vertical during installation, which is convenient and efficient.

[0024] When the lower stand column 1, the upper stand column 2 and the positioning sleeve 3 are found to have errors during installation, and need to be re-adjusted and installed, the worker first unscrews the dust cover 13 to expose the round-end screw rod 12 inside the end block 11, then inserts a hexagonal wrench into the end block 11 and connects it with the hexagonal groove on the outer end of the round-end screw rod 12, then the worker presses the hexagonal wrench down, so that the threaded end of the round-end screw rod 12 moves towards the lock block 9 and connects with the threaded groove on the outer end of the lock block 9, then the worker rotates the hexagonal wrench to drive the round-end screw rod 12 to rotate, the rotation of the round-end screw rod 12 drives the threaded end of the round-end screw rod 12 to move the lock block 9 through the threaded groove on the lock block 9 towards the round-end screw rod 12, until the lock block 9 is completely separated from the lock groove 10 on the wedge-shaped rod 5, then the worker pulls out the wedge-shaped rod 5 to the right through the side plate 4, that is, the unlocking work is completed, and finally the upper stand column 2 is pulled out upwards, and the positioning sleeve 3 is taken out, so that the adjustment work can be carried out for reinstallation.

[0027] In addition, when the lower column 1, the upper column 2 and the positioning sleeve 3 are found to have errors during installation, and need to be re-adjusted and installed, at this time the worker first unscrews the dust cover 13 to expose the round-end screw rod 12 inside the end block 11, then the worker inserts the hexagonal wrench into the end block 11 and connects it with the hexagonal groove on the outer end of the round-end screw rod 12, then the worker presses the hexagonal wrench down, so that the threaded end of the round-end screw rod 12 moves towards the lock block 9 and connects with the threaded groove on the outer end of the lock block 9, then the worker rotates the hexagonal wrench to drive the round-end screw rod 12 to rotate, the rotation of the round-end screw rod 12 will drive the threaded end of the round-end screw rod 12 to move the lock block 9 through the threaded groove on the lock block 9 towards the round-end screw rod 12, until the lock block 9 is completely separated from the lock groove 10 on the wedge-shaped rod 5, then the worker pulls out the wedge-shaped rod 5 to the right through the side plate 4, that is, the unlocking work is completed, finally the upper column 2 is pulled out upwards, and the positioning sleeve 3 is taken out, so that the adjustment work can be carried out for reinstallation.
