AI Technical Summary
The existing step-by-step clamps suffer from excessive wear in certain areas during construction because the connection between the movable clamp head and the hook-shaped clamp rod is fixed in the same position for a long time. This requires replacing the entire step-by-step clamp, increasing construction costs and wasting materials.
A high-strength step-by-step clamp is designed by setting multiple sets of positioning holes on the hook-shaped clamp and equipping it with a movable sleeve. The locking component enables the movable sleeve to slide and be fixed linearly on the hook-shaped clamp, changing the wear point, allowing the movable clamp head to wear at different positions, and allowing severely worn movable sleeves to be replaced individually.
It improves the utilization rate of movable scaffolding, reduces construction costs, avoids material waste, adapts to different construction needs, and extends service life.

[0003] However, in the construction process, the connection between the movable clamp head and the hook-shaped clamping rod is prone to local excessive wear due to long-term fixation at the same position. This is due to the limitation of the preset fastening point of the standardized operation process, which makes the specific position frequently used, further aggravating the wear.
[0004] When the hook-shaped clamping rod is severely worn at a certain position, the entire step by step tight often needs to be replaced. Since the hook-shaped clamping rods at other positions are not fully utilized, this not only increases the construction cost, but also causes material waste. INVENTION CONTENTS

When the movable sleeve frame 3 wears somewhere, the staff can slide the movable sleeve frame 3 to the nearby position and fix it through the locking assembly 6. In this way, the position of the movable clamp head 5 does not change, but the position of the movable sleeve frame 3 changes, thereby changing the wear point. This design allows the movable clamp head 5 to wear at different positions of the movable sleeve frame 3, thereby improving the utilization rate of the movable sleeve frame 3. At the same time, when the movable sleeve frame 3 is seriously worn as a whole, the locking assembly 6 can be removed, and the movable sleeve frame 3 can be replaced separately, greatly reducing the construction cost.
[0027] Specifically, the locking assembly 6 includes a bolt 61, a nut 62, and a gasket 63. The bolt 61 is respectively movably penetrated through the locking hole 4 of the movable sleeve frame 3 and the positioning hole 2 of the hook shape clamping lever 1. The bolt 61 is respectively penetrated through the locking hole 4 of the movable sleeve frame 3 and the positioning hole 2 of the hook shape clamping lever 1, forming a connection point, fixing the movable sleeve frame 3 on the stem of the hook shape clamping lever 1. The nut 62 is threadedly connected with the bottom of the bolt 61. The nut 62 can be tightly matched with the bolt 61, thereby realizing the fixation of the movable sleeve frame 3.

[0031] Specifically, the top of the movable clamping head 5 is fixedly provided with an extension seat 8, and the extension seat 8 extends the knocking area of the movable clamping head 5, facilitating the operation of workers.
[0032] Specifically, the number of gaskets 63 is two, and the two gaskets 63 are arranged one above the other, and the two gaskets 63 further improve the stability of the connection between the bolt 61 and the nut 62 compared with one gasket 63.
[0033] Specifically, the nut 62 is a butterfly nut 62, which facilitates the screwing operation of workers and does not require additional wrench operation.
[0034] Working principle: step-by-step tight is realized by the cooperation of the movable sleeve frame 3 and the hook-shaped clamping rod 1 and the fixation of the locking assembly 6 to fix and connect the building components. First, the workers adjust the positions of the movable sleeve frame 3 and the movable clamping head 5 according to the fixed length, and move the movable sleeve frame 3 to the positioning hole 2 of the appropriate hook-shaped clamping rod 1. Then, the bolt 61 of the locking assembly 6 is respectively inserted through the locking hole 4 of the movable sleeve frame 3 and the positioning hole 2 of the hook-shaped clamping rod 1 to form a connection point, and the movable sleeve frame 3 is fixed on the rod body of the hook-shaped clamping rod 1. Then, the gasket 63 is sleeved on the bolt 61, and the nut 62 is installed, so as to fix the movable sleeve frame 3. After fixing, the workers can knock the movable clamping head 5 to work. When the movable sleeve frame 3 is worn at some place, the workers can slide the movable sleeve frame 3 to the nearby position and fix it to change the wear point. When the movable sleeve frame 3 is seriously worn as a whole, the locking assembly 6 can be removed to replace the movable sleeve frame 3 alone.
