[0026] It should be noted that through the cooperation of the first connecting stud 16 and the nut, the connection effect between the first adjusting plate 5 and the second adjusting plate 6 is strengthened. At the same time, it can play a role in supporting and positioning the first fixing frame 13, the second fixing frame 14 and the mounting frame 1, thereby preventing the electric hoist from falling.

[0027] In an alternative embodiment: The first traveling wheels 9 are in contact with the surface of the I-shaped main beam 2, and the second traveling wheels 15 are in contact with the surface of the I-shaped main beam 2.

When the first adjusting plate 5 and the second adjusting plate 6 approach each other, the first traveling wheel 9 and the second traveling wheel 15 can move onto the I-shaped main beam 2, and both the first traveling wheel 9 and the second traveling wheel 15 contact the I-shaped main beam 2. The first adjusting plate 5 and the second adjusting plate 6 can be sleeved on the second connecting stud 20. By tightening the nut, the first adjusting plate 5 and the second adjusting plate 6 can be fixed on the fixed seat 11. By tightening the nut, the tightened nut is threadedly installed on the first connecting stud 16, so that the first fixing frame 13 and the second fixing frame 14 can be connected and fixed, thereby strengthening the connection effect between the first adjusting plate 5 and the second adjusting plate 6, and at the same time, it can play a role in supporting and positioning the first fixing frame 13, the second fixing frame 14 and the mounting frame 1, and further prevent the electric hoist from falling;
