It should be understood that the present embodiment is only exemplary to provide the first gear in the form of a hollow structure to achieve the detachable connection of the first gear with the bolt cap or the nut, and those skilled in the art should understand that any type of detachable connection is suitable for the present invention.

Further, for example, when the first gear is detachably connected with the bolt cap or the nut, a slip prevention structure is arranged between the first gear and the bolt cap or the nut. The slip prevention structure includes a friction washer or the like provided in a hollow structure, and is not limited thereto.

In one example according to the present invention, as shown in fig. 2, the middle of the first gear 201 is provided with a hexagonal hollow structure. The first gear 201 is a hexagon socket gear so as to be capable of matching screw connectors with different connector shapes, which are commonly called universal screwdrivers. Thereby being suitable for screws with different shapes. Meanwhile, the hexagonal edges and corners can also be used as a slipping prevention structure in a hollow structure, and slipping can be avoided when the bolt cap or the nut is locked.

With continued reference to fig. 2, the second gear 202 has a gear shape matched with the first gear 201, when the second gear 202 is rotated, the second gear 202 applies a torque to the tooth portion of the first gear through the tooth portion, so as to drive the first gear 201 to rotate, and when the first gear 201 is rotated, the bolt cap or nut matched with the first gear is driven to rotate, so as to lock the bolt cap or nut.

In an example according to the present invention, the connection portion of the locking tool and the second gear is made by casting a magnet or the second gear is made by casting a magnet. The connecting part of the locking tool and the second gear is made by casting the magnet or the second gear is made by casting the magnet, so that the locking tool can be quickly connected with the bolt cap and the nut in the locking process, the bolt cap and the nut can be quickly positioned, the manual connection of the first gear and the connection of the bolt cap or the nut is replaced, and the time and the labor are saved.

When an accessory to be locked is locked, a torque is usually applied to the bolt cap or the nut through a locking tool, the bolt cap or the nut is subjected to a rotating torque force in a plane where the bolt cap or the nut is located, the locking or fastening is realized through the rotation, for example, when a screw is subjected to a torque force consistent with the rotating direction of a thread of the screw, the screw is rotated, and downward fastening is realized. Therefore, when the locking tool is mated with the bolt cap or nut, the dimensions in the plane of the bolt cap or nut and the dimension in the direction in which the bolt cap or nut extends often determine the environment in which the locking tool can operate.

Because the first gear and the second gear are matched to drive the bolt cap or the nut to rotate, the plane where the bolt cap or the nut is located is set to be driven to rotate by the gear, and the occupied space during gear driving is far smaller than the occupied space during driving by other driving parts (such as driving rods), so that the bolt cap or the nut can be locked without applying moment to the bolt cap or the nut in a large space range, the operation space of the locking tool can be reduced, and the locking tool can adapt to a wider operation environment.
