DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) Please refer to FIGS. 1 to 6 for an exemplary embodiment of the present invention. A magnetic sweeper of the present invention includes a main body 1, a magnetic mechanism 2 and a handle 3.

(8) The magnetic mechanism 2 includes at least one connector 21, a magnet unit 22 and a bar 23, the at least one connector 21 is connected to the main body 1 and movable in a pull direction 7, the magnet unit 22 is disposed at a side of the at least one connector 21, the bar 23 is swingably disposed at another side of the at least one connector 21, the bar 23, the at least one connector 21 and the magnet unit 22 are movable with each other in the pull direction 7, and the handle 3 is swingably connected to the main body 1.

(9) The handle 3 which is swingable relative to the main body 1 provides a variety of different angles for users to freely adjust according to various needs. Since the bar 23 is also swingable and an axis which the bar 23 is rotatable about is parallel to an axis which the handle 3 is rotatable about, the bar 23 can be pulled at required one of various angles and be driven by and movable with the handle 3 so that the bar 23 does not impede, limiting the swing movement of the handle 3.

(10) Specifically, the magnetic sweeper further includes a pivot mechanism 5, the pivot mechanism 5 includes a first pivot portion 51, a second pivot portion 52 and a shaft 53, the first pivot portion 51 is disposed on the main body 1, the shaft 53 is disposed through and connects the first pivot portion 51 and the second pivot portion 52, the handle 3 is disposed on the second pivot portion 52, and the handle 3 is rotatable about the shaft 53 relative to the main body 1.

(11) Preferably, the handle 3 is detachably connected to the second pivot portion 52, which is convenient for storage or carrying, and which facilities replacement when the handle 3 is damaged.
