[0004] In actual construction, the thickness of some buildings decreases with the increase of height. The steel beams in the supporting platform are fixed on the wall.
[0005] As shown in Figure 7 , this results in the gradual increase of the distance L1 between the center of the tower crane and the wall, and the operator needs to adjust the position of the movable stool on the fixed stool according to the actual situation. The positions of the two fixed stools on each steel beam are the same. The shape of the threaded hole on the fixed stool and the distance between adjacent threaded holes are equal to the shape of the threaded hole on the movable stool and the distance between adjacent threaded holes.

The distance between the adjacent threaded holes on the sliding block 2 is equal to the distance between the adjacent threaded holes on the fixed horse stool 1. And the shape of the threaded hole on the sliding block 2 is same as the shape of the threaded hole on the movable horse stool 11.
[0043] By moving the position of the sliding block 2 in the shell 12, the threaded hole on the sliding block 2 is corresponding to the threaded hole on the movable horse stool 11.
[0044] The length dimension of the sliding block 2 is 0.7-0.8 times of the length dimension of the inner hole of the shell 12. In the embodiment, the length dimension of the sliding block 2 is 0.75 times of the length dimension of the inner hole of the shell 12. The sliding block 2 has enough moving space to facilitate the operator to adjust the position of the sliding block 2.
[0045] In order to reduce the cost of making the sliding block 2. The vertical section of the sliding block 2 is inverted concave shape.
[0046] Two guide plates 4 are fixedly arranged at the inner hole of the shell 12, and the two ends of the two guide plates 4 are respectively fixed with the two sides of the inner wall of the shell 12. The two guide plates 4 all pass through the sliding block 2, and the guide plate 4 is slidingly connected with the sliding block 2.
[0047] In order to further strengthen the bearing capacity of the sliding plate, the inner wall bottom of the shell 12 is uniformly provided with a plurality of support plates 41, and the plurality of support plates 41 are located between the two guide plates 4. The top of the plurality of support plates 41 is in contact with the top wall of the recess in the sliding block 2. And the plurality of support plates 41 are located between the two rows of threaded holes on the sliding block 2, and the screw rod 51 passing through the threaded hole does not contact the support plate 41.
[0048] The two ends of the sliding block 2 are fixedly provided with the connecting plate 33.
[0049] The shell 12 is provided with the fixed assembly 3, and the fixed assembly 3 fixes the position of the sliding block 2.
[0050] The fixing assembly 3 comprises two auxiliary housings 31, each of which is open on one side and hollow inside, and each of which is fixedly arranged at the two ends of the housing 12. Each auxiliary housing 31 is provided with a push block 32, which is shaped to match the shape of the inner hole of the corresponding auxiliary housing 31, and the push block 32 is in sliding connection with the corresponding auxiliary housing 31.
[0051] One end of the push block 32 is located in the housing 12, and the push block 32 can also completely enter the corresponding auxiliary housing 31.
[0052] The connecting plate 33 is opposite to the corresponding push block 32, and each auxiliary housing 31 is provided with a movement assembly 5, which drives the corresponding push block 32 to move.
[0053] The two sides of the push block 32 are respectively attached to one side of the two guide plates 4.

The screw rod 51 is arranged in the corresponding auxiliary housing 31, and the screw rod 51 is in threaded connection with the corresponding auxiliary housing 31.
[0055] The implementation principle of the above embodiment is as follows:
[0056] Before adjusting the sliding block 2, the two screw rods 51 are first rotated, the screw rods 51 drive the corresponding push blocks 32 to move, so that the push blocks 32 completely enter the corresponding auxiliary housings 31 or a large distance exists between the push blocks 32 and the sliding block 2.
[0057] The operator uses a tool to push the sliding block 2 to move, and after the sliding block 2 is moved to a proper position.
[0058] The operator first rotates one of the screw rods 51, the screw rod 51 drives the push block 32 to move, and the push block 32 stops rotating the screw rod 51 after contacting the sliding block 2.
[0059] Next, the operator uses a tool to rotate the other screw rod 51, so that the two push blocks 32 are in contact with the connecting block. It is explained that one side of the connecting plate 33 is completely in contact with the push block 32, but one side of the push block 32 is partially in contact with the connecting plate 33 and the other side is in contact with one side of the sliding block 2.
[0060] By continuously adjusting the two screw rods 51, the two push blocks 32 fix the position of the sliding block 2. During the debugging process, the position of the sliding block 2 is ensured not to change.
[0061] Next, align one of the threaded holes on the movable horse stool 11 with the threaded hole on the sliding block 2, and connect the movable horse stool 11 and the sliding block 2 with a bolt.
[0062] Finally, connect the movable horse stool 11 and the support leg on the climbing frame with a bolt.
[0063] The embodiments of the specific embodiment are the preferred embodiments of the utility model, not limited to the protection scope of the utility model, so that: all equivalent changes made according to the structure, shape and principle of the utility model should be covered in the protection scope of the utility model.
