[0026] In a preferred embodiment: the connecting component 9 includes a trapezoidal block 901, the outer wall of the trapezoidal block 901 is provided with a limiting groove 902, the outer wall of the trapezoidal block 901 is fixedly assembled with one end of an extension rod 903, the other end of the extension rod 903 is fixedly assembled with a limiting block 904, the outer wall of the limiting block 904 is provided with a placement groove 905, the inner wall of the limiting groove 902 is threadedly connected with a bolt 907, the outer wall of the placement groove 905 is provided with a trapezoidal block 906, the outer wall of the trapezoidal block 906 is fixedly assembled with one end of a connecting rod 908, and the other end of the connecting rod 908 is fixedly assembled with a limiting plate 909.

[0027] In the above structure, after completing the protection measures for the wheel hole of the pulley body 1, the staff operates the connecting rod 908 to drive the limit plate 909 to position toward the inner wall of the placement groove 905. When the limit plate 909 is placed on the inner wall of the placement groove 905, the staff rotates the connecting rod 908, and the limit plate 909 is driven by the connecting rod 908 to rotate ninety degrees on the inner wall of the placement groove 905 and then stop operating. Finally, the staff realizes the limiting function of the protective shell 2 by threading the bolt 907 with the trapezoidal block 1 901, the trapezoidal block 2 906 and the limit groove 902 opened on the outer wall of the rotating rod 7 and the pressure rod 8.

[0028] In a preferred embodiment, the limiting grooves 902 are respectively opened on the outer walls of the trapezoidal block 1 901 , the trapezoidal block 2 906 , the rotating rod 7 and the compression rod 8 , and the sliding grooves 11 are opened on the outer wall of the compression rod 8 .

[0035] In the above structure, two sets of connecting components 9 are used to limit the rotating rod 7 and the pressure rod 8, so as to prevent the rotating rod 7 and the pressure rod 8 from rotating when the equipment is in operation.

[0036] Working principle: When protecting the wheel hole of the pulley body 1, the staff first puts the protective shell 2 into the wheel hole of the pulley body 1, and then rotates the rotating rod 7, so that the rotating rod 7 drives the fixing block 5 and the threaded rod 3 to be threadedly connected with the inner wall of the protective shell 2 during the rotation process.

After completing the pulley body 1, the staff pushes the connecting rod 908 so that the connecting rod 908 drives the limiting plate 909 to be placed on the inner wall of the placement groove 905. When the limiting plate 909 is placed on the inner wall of the placement groove 905, the staff rotates the connecting rod 908, and drives the limiting plate 909 to rotate ninety degrees on the inner wall of the placement groove 905 through the connecting rod 908, and then stops the operation. Finally, the staff uses bolts 907 to thread the limiting groove 902 opened on the outer wall of the trapezoidal block 1 901, the trapezoidal block 2 906, the rotating rod 7 and the pressure rod 8, and finally realizes the limitation of the protective shell 2.
