[0030] When the height of the mechanical hand needs to be adjusted, the first torsion block 7 is first rotated to rotate the first threaded rod 4, after the first threaded rod 4 is rotated, the position of the moving block 5 can be adjusted, since the density of the first threaded rod 4 is small, a small number of rotations of the first threaded rod 4 can realize a large displacement of the mechanical hand, after the height is adjusted to the required height, the second torsion block 15 is shaken to rotate the second threaded rod 13, since the density of the threads of the second threaded rod 13 is large, a unit number of rotations of the second threaded rod 13 can realize a small displacement of the mechanical hand, by using this mode, more accurate height adjustment can be realized, the first motor 10 and the second motor 16 can be used to realize more efficient height adjustment of the mechanical hand, and within the adjustable range, any height and angle can be adjusted.

[0031] Working principle: when using, the angle of the mechanical hand can be adjusted by the L-shaped rotating rod 1 cooperating with the guide vertical rod 2, which is convenient for the operation of the staff.

[0032] When the height of the mechanical hand needs to be adjusted, the first torsion block 7 is first rotated to rotate the first threaded rod 4, and after the first threaded rod 4 is rotated, the position of the moving block 5 can be adjusted. Since the density of the first threaded rod 4 is small, a small number of rotations can realize a large displacement of the mechanical hand. After the height is adjusted to the vicinity of the required height, the second torsion block 15 is shaken to drive the second threaded rod 13 to rotate. Since the density of the second threaded rod 13 is large, the displacement distance of the mechanical hand is small for each unit number of rotations. By using this method, more accurate height adjustment can be realized. In combination with the first motor 10 and the second motor 16, more efficient height adjustment of the mechanical hand can be realized, and the height and angle can be adjusted at any position within the adjustable range.

When the broken fuse tube needs to be removed, the mechanical hand at the top of the device can first grab the broken fuse tube, and then take it out after being pushed. Each limiting block 24 can be installed with different limiting plates 27 through the bolts 25, so as to adapt to fuse tubes of different sizes. Through the setting of the illuminating lamp 22, even if the falling type fuse tube replacement operation is performed at night, the installation of the fuse tube can also be clearly seen.
