[0028] Working principle:

[0029] The first step is that when in use, the notch at the top of the bit 13 can be aligned with the bayonet at the bottom of the handle 1 and inserted. The bit 13 will be adsorbed and fixed by the first magnet 9 at the bottom of the handle 1. The bayonet at the bottom of the handle 1 is a regular hexagon, which just matches the shape of the top of the bit 13. If the required length is longer, first align the notch at the top of the long connecting rod 12 with the bayonet at the bottom of the handle 1 and insert it. The first magnet 9 adsorbs and fixes the long connecting rod 12, and then the bit 13 is inserted from the bayonet at the bottom of the long connecting rod 12. The second magnet 14 in the long connecting rod 12 will adsorb and fix the bit 13 to complete the combination. If the torque required for use is large, the rotating rod 8 can be pulled out, and then the rotating rod 8 is selected to align it with the notch at the side end of the handle 1. The torque during rotation is increased through the principle of leverage. Different combinations are completed through the bayonet openings opened by the first magnet 9, the second magnet 14 and the handle 1 and the long connecting rod 12, thereby achieving the effect of easy combination and not easy to loosen.

[0030] In the second step, after use, the bit 13 is placed inside the short card block 4, and the long connecting rod 12 is placed inside the long card block 3, and the storage bucket 2 is inserted into the opening at the top of the handle 1. During the insertion process, the long card block 3 and the short card block 4 will be squeezed by the handle 1 to rotate and retract into the storage bucket 2. During this process, the storage bucket 2 will first press the slide plate 5 to overcome the elastic force of the spring 6 and slide down. When the Y-shaped fixing block 15 passes through the opening at the top of the storage bucket 2, the Y-shaped fixing block 15 is rotated to make the Y-shaped fixing block 15 clamp the storage bucket 2, and the storage is completed. By storing the long connecting rod 12 and the bit 13 inside the storage bucket 2, and then storing the storage bucket 2 inside the handle 1, the effect of easy storage and easy carrying is achieved.
