Description

Technical Field

[0001] The utility model relates to the field of fixed suckers, in particular to a strong magnetic fixed sucker with a switch. Background Art

[0002] A fixed suction cup is a tool that uses magnetic force to fix. It usually consists of a suction cup and a magnet. The suction cup part of the fixed suction cup is usually made of plastic, rubber or other non-magnetic materials, while the magnet is made of a material with strong magnetism, such as neodymium iron boron or ferrite. When the suction cup is opposite to the magnet, the magnetic field of the magnet will magnetize the suction cup, thereby generating attraction.

[0003] In view of the current fixed suction cup field, corresponding solutions have been formulated for the following existing problems:

[0004] The fixed suction cup usually uses a permanent magnetic force to complete the magnetic fixing work. The magnetic force cannot be adjusted and the usage scenarios are limited. When the fixed suction cup needs to be removed, the traditional fixed suction cup usually takes a forced removal method to separate the fixed suction cup from the outer surface of the fixed object. When faced with a fixed suction cup with a strong magnetic force, the required force is large, and forced removal is likely to cause damage to the outer surface of the fixed object, which is inconvenient for users to operate and has poor flexibility in use. The unadjustable magnetic force limits the scope of use of the fixed suction cup, and it is easy to attract other metal debris during the use of the fixed suction cup, which is easy to cause damage to the fixed suction cup itself and the fixed object.
