Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
As shown in Figure 1-2, a kind of hand-held sander, including bottom deck assembly, shell 1 and the driving assembly being located in shell 1, bottom deck assembly includes base plate the 33rd, bottom plate gasket 40 and the base pad 41 setting gradually from top to bottom, also include wobble component 2 and offset assembly, wobble component 2 includes elastic cylinder 28, elastic cylinder 28 one end is affixed with shell 1, the other end is affixed with bottom deck assembly, bottom deck assembly is connected with the main shaft driving assembly, it is provided with eccentric block 36 between base plate 33 and base pad 41, drive assembly to drive described bottom deck assembly eccentric swing by described eccentric block 36.Wobble component 2 includes 4 groups being symmetrically distributed on base plate 33, is specifically distributed in four corner location of base plate 33.
Eccentric block 36 has the connecting portion 361 being connected with main shaft, and is located at the secter pat 362 below connecting portion 361.
Elastic cylinder 28 upper end is connected with shell 1 by swinging pin connection seat 27, and lower end is connected with base plate 33 by swinging foot press plate 29.Elastic cylinder 28 includes the some sub-cylinder 281 circumferentially arranging, and described sub-cylinder 281 encloses and forms the cylinder that Intermediate Gray has cavity, extends and be provided with support column 282 bottom own elasticity cylinder 28 in cavity, and support column 282 height is less than or equal to described cavity height.Support column 282 also further improves the intensity of elastic on the premise of ensureing that elastic cylinder 28 is steady, flexible and swing.Compare the elastic cylinder 28 of solid type, i.e. elastic cylinder 28 is formed by the elastic pillar of a solid type, and the elastic cylinder 28 of the present invention is more flexible, it is more steady to swing.
