[0033] In this embodiment, a cylinder 112 with a screw hole 1121 is provided on the side of the connecting shell 11 facing the metal connecting part 12, and the magnet is fixed on the cylinder 112 with the screw 114. The connecting shell 11 and the metal connecting part 12 are adsorbed and connected by relying on the magnetic force of the magnet, so as to achieve the purpose of covering the connecting shell 11 on the metal connecting part 12. This method of covering by relying on magnetic force can keep the side of the connecting shell 11 facing away from the metal connecting part 12 intact, and the appearance is beautiful. The connecting shell 11 can be covered on the metal connecting part 12 without opening additional screw holes, and dust is not easy to accumulate. When the connecting shell 11 and the metal connecting part 12 need to be disassembled, they can also be directly disassembled manually without relying on tools to tighten or loosen the screws, and installation and disassembly are convenient and easy.

The cross-sectional shape of the magnet can be circular, square or elliptical. Preferably, the cross-sectional shape of the magnet is circular, that is, the magnet is a cylinder with a through hole, and a concave surface 1132 is provided on one side of the magnet. The concave surface 1132 is used to accommodate the nut 1141 when the screw 114 is screwed to the cylinder 112. The concave surface 1132 accommodates the nut 1141 to prevent excessive force from being applied during the installation of the screw 114, which may cause damage to the side of the magnet.

[0047] In an embodiment of the seat adjustment device, the number of the cylinders 112 can be multiple, at least one, and correspondingly, magnets can be set on the multiple cylinders 112 to enhance the magnet adsorption force, so as to ensure that the connection housing 11 and the metal connecting member 12 are not easily detached.

[0048] In one embodiment of a seat adjustment device, the handle is shaped like a long strip as a whole, which is convenient for the user to hold the handle and rotate it to adjust the angle of the seat back 3 when sitting down. The long strip shape also facilitates calibration and positioning when the user removes or installs the connecting shell 11, maintaining a good grip.

[0049] The utility model also relates to a seat, comprising the seat adjusting device in the foregoing embodiment.
