[0075] When the magnet support 4 is located at the counterclockwise end side of the arc track groove 18, the first magnet 12 is located directly above the first magnetic conductive boss 15, and the second magnet 13 is located directly above the second magnetic conductive boss 16, forming a magnetic closure and being in a magnetic adsorption state.

[0076] Specific:

[0077] When the first magnet 12 is located directly above the first magnetic boss 15 and the second magnet 13 is located directly above the second magnetic boss 16, the raised portions of the first magnetic boss 15 and the second magnetic boss 16 are in close contact with the working surface of the bolt to be loaded and unloaded; according to the magnetic characteristics of the magnet, the magnetic lines of flux start from the N pole of the second magnet 13, pass through the second magnetic boss 16, and pass through the working surface of the bolt to be loaded and unloaded, and return from the first magnetic boss 15 to the S pole of the first magnet 12, forming a magnetic circuit, thereby realizing the adsorption function.

[0078] Magnetic closing state:

[0079] When the magnet support 14 is located at the clockwise end side of the arc track groove 18, the first magnet 12 and the second magnet 13 are not located on the first magnetic conductive boss 15 and the second magnetic conductive boss 16, and no magnetic closure is formed, and the magnet is in a magnetic closed state.

[0080] Specific:

[0081] When the first magnet 12 and the second magnet 13 are not on the first magnetic boss 15 and the second magnetic boss 16, or the first magnet 12 and the second magnet 13 are partially on the second magnetic boss 16, according to the magnetic characteristics of the magnets, the magnetic flux lines start from the N pole of the second magnet, pass through the second magnetic boss 16 and return to the S pole of the first magnet 12, and only a small part of the magnetic flux lines pass through the working surface of the bolt to be loaded and unloaded, thereby realizing the disconnection function.

[0082] During specific use, first, the annular base is put on the bolt to be loaded and unloaded, and the first magnetic conductive boss 15 and the second magnetic conductive boss 16 are closely in contact with the working surface of the bolt to be loaded and unloaded; then the magnet support 14 is rotated counterclockwise to the end of the arc track groove, and the magnetic adsorption function is realized; next, the rotating bar 4 of the upper cover 1 is rotated, and the first bevel gear 19 is driven to rotate by the rotation of the rotating bar 4, and the first bevel gear 19 is driven to rotate by the rotation of the second bevel gear 23, and the second bevel gear 23 causes the spiral rotating shaft 25 to rotate, and the rotation of the spiral rotating shaft 25 is converted into a translation through the driven tooth portion 21, and the guide portion 22 drives the transmission member to translate, and finally the rubber block 20 is in close contact with the nut of the bolt to be loaded and unloaded, realizing the function of tightening the nut and avoiding the joint rotation of the screw and the nut; at this time, a wrench or other tool is used at the other end of the bolt to load and unload the screw of the bolt. Due to the tightening effect of the fastener 7 and the adsorption effect of the magnetic force, the user only needs to turn the wrench, and the torque generated by loading and unloading the bolt is resisted by the tightening base 2 and the magnetic base 3.

[0083] The bolt loading and unloading device described in the present invention utilizes the rotation of the upper cover to drive the fastener to move horizontally to tighten or loosen the bolt, and the rotation of the magnet support drives the magnet to absorb or loosen the component to achieve the effect of tightening or loosening the bolt. It has a simple structure and is easy to operate. It is suitable for large bolts of various models and is convenient for bolt loading and unloading, thereby improving work efficiency.

[0084] The above embodiment is only one of the implementation methods that can realize the technical solution of the present invention. The scope of protection claimed by the present invention is not limited only to this embodiment, but also includes changes, replacements and other implementation methods that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention.
