As a further improvement of the scheme, the front surface of the telescopic rod is provided with the through hole, and the front surface of the handle is movably connected with the button corresponding to the through hole, so that the length of the handle can be increased, the moment is increased, and the pulling strength is reduced.

As a further improvement of the scheme, the bottom of the telescopic rod is fixedly connected with a sleeve, and the telescopic rod is used for disassembling and assembling the screw at a position with a small space.

As a further improvement of the scheme, the fixing block and the adjusting block are arranged corresponding to the screw, the magnet is used for aligning the screw, and the magnet can be adsorbed when the screw is removed, so that the magnet is prevented from falling in a narrow environment and is not taken easily.

Compared with the prior art, the utility model has the beneficial effects that:

When the screw is disassembled, the screw can be directly aligned with the magnet, and then the worm is rotated, so that the worm drives the cross beam to move through the tooth block, further the adjusting block moves, the screw is clamped, the rotating handle is unscrewed, the handle can be rotated through the rotating shaft when the left and right distances are insufficient, the angle is changed, the spanner head is enabled to fall vertically, and then the handle is rotated.
