[0025] The structures, proportions, sizes, etc. illustrated in this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed herein, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and objectives that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0026] Please see Figures 1 to 7 This utility model provides a technical solution: an eccentric grinding machine, including a handle 1 and a grinding disc 2. One end of the handle 1 is fixedly connected to a drive motor 3, and the output end of the drive motor 3 is fixedly connected to a mounting block 4. The surface of the mounting block 4 has two symmetrically arranged limiting grooves 5. The middle of the upper surface of the grinding disc 2 has a sliding groove 6. The mounting block 4 is slidably connected to the grinding disc 2 through the sliding groove 6. The upper surface of the grinding disc 2 near the mounting block 4 has two symmetrically arranged adjusting components 7. The adjusting components 7 are inserted into the limiting grooves 5 on the surface of the mounting block 4. When the operator needs to adjust the eccentricity of the device, the operator can push the adjusting components 7 to release the restriction on the mounting block 4 and fix the adjusting components 7 at the same time, so that the mounting block 4 can slide in the sliding groove 6 on the grinding disc 2, thereby adjusting the eccentricity of the device. After the adjustment is completed, the operator can reset the adjusting components 7, thereby limiting the mounting block 4 and completing the adjustment of the eccentricity of the device.

[0027] The adjustment component 7 includes multiple slots 71 symmetrically opened on both sides of the slide 6. The grinder is slidably connected to multiple limiting posts 72 through the slots 71. A return spring 73 is fixedly connected to one end of the limiting post 72 away from the slide 6. The other end of the return spring 73 is fixedly connected to the grinding disc 2 through the slots 71.

[0028] The upper surface of the grinding disc 2 is provided with slide rails 74 corresponding to the slots 71. The surface of the limiting post 72 is fixedly connected to the connecting post 75. The connecting post 75 is slidably connected to the grinding disc 2 through the slide rails 74. The top of the connecting post 75 is fixedly connected to the push plate 76. With the setting of the push plate 76, the operator only needs to push the push plate 76 to simultaneously push the four limiting posts 72 on one side of the slide rail 6, so that they slide in the slots 71, thereby achieving the effect of saving time and effort, and being convenient and quick. In this way, the efficiency of the operator in adjusting the eccentricity of the device is effectively improved.

[0029] Two symmetrically arranged push rods 77 are fixedly connected to the upper surface of the push plate 76. A fixing bolt 78 is threaded onto the upper surface of the push plate 76 near the push rods 77. Two positioning holes 79, matching the fixing bolts 78, are opened on the upper surface of the grinding disc 2 near the fixing bolts 78. When the operator needs to push the push plate 76, they can twist the fixing bolts 78 to make them rotate out of the positioning holes 79 and separate from the grinding disc 2. The operator can then push the push plate 76 and cause the limiting post 72 to slide together, thereby releasing the limitation post 72 from restricting the mounting block 4. The operator can then adjust the position of the mounting block 4 on the grinding disc 2, thus adjusting the eccentricity of the device. This effectively improves the operator's work efficiency, achieving a time-saving, labor-saving, convenient, and quick effect.

[0030] There are eight slots 71, which are divided into two groups. The two groups of slots 71 are symmetrically located on the two side walls of the slide 6. Multiple limit posts 72 correspond one-to-one with each slot 71.

[0031] The push plate 76 has a threaded hole on its surface corresponding to the fixing bolt 78. The push plate 76 is threadedly connected to the fixing bolt 78 through the threaded hole, and the fixing bolt 78 is threadedly connected to the grinding disc 2 through the positioning hole 79.

[0032] In this invention, the working steps of the device are as follows:

[0033] When the operator needs to adjust the eccentricity of the device, simply turn the fixing bolt 78 on the upper surface of the grinding disc 2 to separate it from the positioning hole 79 on the grinding disc 2, and push the push rod 77. This push rod 77 will cause the push plate 76 to slide along the slide rail 74 on the grinding disc 2, thereby causing the limiting post 72 in the slot 71 to slide together. This will separate the limiting post 72 from the limiting groove 5 on the mounting block 4, thus releasing the restriction on the mounting block 4. At the same time, turning the fixing bolt 78 will thread it into the corresponding positioning hole 79 on the grinding disc 2, thereby fixing the push plate 76 and effectively preventing the limiting post 72 from shifting during eccentricity adjustment. The mounting block 4 is inserted and jammed, allowing the operator to push the mounting block 4 to slide within the groove 6 on the grinding disc 2, thus adjusting the eccentricity of the device. Simultaneously, while pushing the limiting post 72 to slide along the slot 71, the limiting post 72 compresses the return spring 73. After adjusting the mounting block 4, the operator only needs to turn the fixing bolt 78 to release the restriction on the push plate 76, allowing the limiting post 72 to slide along the slot 71 under the elastic potential energy of the return spring 73 and insert into the limiting groove 5 on the mounting block 4. Finally, the fixing bolt 78 is turned to make it threaded into the positioning hole 79 on the grinding disc 2, completing the fixing of the adjustment component 7.

[0034] In the description of this specification, the terms "connection", "installation", "fixing", "setting", etc. are interpreted in a broad sense. For example, "connection" can be a fixed connection or an indirect connection through an intermediate component without affecting the relationship between components and the technical effect. It can also be an integral connection or a partial connection. In such cases, those skilled in the art can understand the specific meaning of the above terms in this utility model or utility model according to the specific circumstances.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
