A first fixing ring 5 is fixedly installed on the side of the first anti-corrosion sleeve 4 near the rod 2. A second anti-corrosion sleeve 6 is fitted on the surface of the rod 2. A second fixing ring 7 is fixedly installed on the side of the second anti-corrosion sleeve 6 near the first fixing ring 5. The surfaces of the first fixing ring 5 and the second fixing ring 7 are provided with a fixing ring. The fixed sleeve 8 has a limiting opening 9 on the side near the first fixing ring 5 and the second fixing ring 7. A screw hole 10 is formed on the surface of the fixed sleeve 8, and a threaded rod 11 is threaded into the screw hole 10. A fastening nut 16 is threaded into the surface of the stud 1. A flat washer 15 is placed on the bottom surface of the fastening nut 16, and a spring washer 14 is placed on the bottom surface of the flat washer 15. The fastening nut 16 and the flat washer 14 are connected to the surface of the stud 1. 15 and spring washer 14 firmly fix the machine to the anchor bolts, allowing the anchor bolts to be quickly connected or separated from the machine. There are two sets of fixing sleeves 8 and threaded rods 11, symmetrically distributed on both sides of the rod body 2. These two sets of fixing sleeves 8 and threaded rods 11 firmly secure the first fixing ring 5 and the second fixing ring 7 together, preventing them from falling off during use and affecting the sealing of the anti-corrosion sleeve, allowing external moisture and oxygen to enter and corrode the anchor bolts. The first anti-corrosion sleeve 4 is located away from the first fixing ring 5. With the end in a sealed state, the fixing ring can be moved to the designated position after the surface of the first anti-corrosion sleeve 4 is attached to the bottom surface of the hook 3. No manual positioning by the operator is required, and the sealing performance of the anti-corrosion sleeve is improved. The first fixing ring 5 and the second fixing ring 7 are attached to each other. The size of the limiting port 9 is the same as the size after the first fixing ring 5 and the second fixing ring 7 are attached. The first fixing ring 5 and the second fixing ring 7 are firmly fixed in use by the fixing sleeve 8 to prevent them from falling off during use, affecting the sealing performance of the anti-corrosion sleeve, and allowing external moisture and oxygen to enter and cause the anchor bolts to be corroded.
