Detailed Description
The invention is described in further detail below with reference to specific embodiments and the attached drawing figures:
referring to fig. 1-7, the gasket structure for the angle grinder, which prevents the outer pressing plate from being locked more and more, comprises an output shaft 1, wherein an inner pressing plate 2, a cutting blade 3, a pressing plate gasket 4 and an outer pressing plate 5 are sequentially arranged on the output shaft 1 from inside to outside.
The inner pressure plate 2 is positioned relative to the output shaft 1 to restrict rotation relative to the output shaft 1 so that the inner pressure plate 2 rotates with the output shaft 1 as the output shaft rotates.
In this embodiment, the output shaft 1 is provided with a plurality of notches 11 to form a first non-circular portion, the inner pressing plate 2 is provided with a second non-circular portion 21 adapted to the first non-circular portion, specifically, referring to fig. 6 and 7, the notches 11 may be opened on other main body portions of the non-threaded portion of the output shaft 1, and the threaded portion passes through the mounting hole of the inner pressing plate 2 to be connected to the outer pressing plate 5. The second non-circular portion 21 may be provided on the bottom surface of the inner press plate 2, and this portion may be formed to extend over a main portion of the inner press plate 2, and the mounting hole of the inner press plate 2 is located within a range surrounded by this portion.
As shown in fig. 5, a first extending portion 22 is formed by extending the mounting hole of the inner press plate 2, the first extending portion 22 can be located on the top surface of the inner press plate 2, a plurality of positioning holes 23 are formed in the first extending portion 22, and the positioning holes 23 are, for example, slots.
After the inner pressure plate 2 is installed on the output shaft 1, the cutting blade 3 can be sequentially installed on the first extension part 22 on the inner pressure plate 2, and the installation hole of the cutting blade 3 can be matched with the shape and size design of the first extension part 22 according to actual needs.
In this embodiment, when the cutting blade 3 is mounted at the first extending portion 22, at least a part of the first extending portion 22 extends to above the cutting blade 3, and the specific extending size can be determined according to the actually required thickness of the pressing plate pad 4, that is, when the pressing plate pad 4 is mounted on the cutting blade 3, the upper surface of the pressing plate pad 4 is flush with or tends to be flush with the upper surface of the first extending portion 22 extending to above the cutting blade 3.
The clamp plate gasket 4 can be relative interior clamp plate 2 is fixed a position to it is relative to the restriction interior clamp plate 2 rotates, is provided with a plurality of setting elements 41 that can pass the mounting hole of cutting piece 3 on the clamp plate gasket 4, and setting element 41 is if the pin buckle, and setting element 41 is used for with the locating hole 23 adaptation of interior clamp plate 2, and when setting element 41 assembled in locating hole 23 department, the relative interior clamp plate 2 of clamp plate gasket 4 was fixed a position, and in this embodiment, setting element 41 can be provided with two, and the symmetry sets up, but setting element 41 and locating hole 23 one-to-one set up.
