DETAILED DESCRIPTION

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0022] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model is an adjustable handle grinder, comprising a first polishing disc 1 and a second polishing disc 2, wherein the first polishing disc 1 and the second polishing disc 2 are oppositely fitted and arranged, and connecting grooves are provided on the outer ring surfaces of the first polishing disc 1 and the second polishing disc 2, and the upper and lower connecting grooves are combined to form a slot 11, and a plug plate 12 for fixing the first polishing disc 1 and the second polishing disc 2 together is inserted into the slot 11, and the end of the plug plate 12 facing the outside is bent upward to form a connecting portion 3, and a cross plate 4 is installed at the other end of the connecting portion 3, and a fan-shaped column 5 is vertically installed at the end of the cross plate 4 away from the connecting portion 3, and a plurality of fan-shaped columns 5 are combined to form a connecting column, and an adjusting handle for adjusting the height of the first polishing disc 1 and the second polishing disc 2 is installed on the outside of the connecting column.

[0024] In this embodiment, the adjustment handle includes a connecting tube 6, a positioning column 13, a push block 8, a compression spring 7, a connecting seat 9 and a plurality of fixing plates 10. The connecting tube 6 is installed on the outside of the connecting column. The top surface of the fan-shaped column 5 is provided with grooves, and the plurality of grooves are combined to form a positioning groove 14 of a rectangular structure. A positioning port is provided on the top surface of the connecting tube 6 directly opposite to the positioning groove 14. One end of the positioning column 13 is inserted into the positioning groove 14 through the positioning port. The other end of the positioning column 13 is fixedly connected to the push block 8. The compression spring 7 is sleeved on the outside of the positioning column 13. The connecting seat 9 is arranged above the push block 8. A plurality of fixing plates 10 are installed between the connecting seat 9 and the connecting tube 6. Channels for fingers to be inserted are formed between the fixing plates 10.

[0025] Among them, a plurality of fixing holes are provided on the connecting seat. After the screws pass through the fixing holes, the adjusting handle can be fixed on the motor shaft of the grinder to complete the connection between the first polishing disc and the second polishing disc and the motor.

[0026] In this embodiment, an external thread is provided on the outer ring surface of the connecting column, and an internal thread is provided on the inner ring surface of the connecting tube 6. The connecting tube 6 is meshed with the external thread on the connecting column through the internal thread. One end of the compression spring 7 is installed on the connecting tube 6, and the other end is installed on the push block 8.

[0027] In this embodiment, the cross section of the positioning column 13 is a rectangular structure, and the outer side of the positioning column 13 is arranged to abut against the inner side of the positioning groove 14. Of course, the positioning column, the positioning opening and the positioning groove can also be arranged in a polygonal structure.

[0028] In this embodiment, the cross-sections of the slot 11 and the insert plate 12 are both arranged in an hourglass-shaped structure, so that the first polishing disc and the second polishing disc can be connected together, avoiding up and down movement and increasing stability. The second polishing disc and the outer side of the second polishing disc can be positioned through the connecting part to avoid movement forward, backward, left and right.

[0029] In this embodiment, the bottom surface of the transverse plate 4 is arranged to abut against the top surface of the second polishing disc 2, and the second polishing disc can be pressed downward by the transverse plate, thereby increasing the tightness between the first polishing disc and the second polishing disc.

[0030] In this embodiment, the grinding surfaces of the first polishing disc 1 and the second polishing disc 2 are both arranged to face outwards, so that after replacement, the grinding surface of the second polishing disc can be arranged to face downwards.

[0031] When in use, the height of the first polishing disc and the second polishing disc can be adjusted according to different grinding tools, especially some tools with pits. In order to make the first polishing disc enter the pit smoothly, when adjusting, first pull the positioning column upward through the push block. After the positioning column is moved out of the positioning groove, the connecting tube can be rotated to make the connecting tube move up and down along the connecting column to change the extended length of the first polishing disc and the second polishing disc. After the distance is determined, release the push block again, and the positioning column can be inserted into the positioning groove again through the rebound of the compression spring, so as to position the connecting tube and avoid the connection tube from rotating again.

[0032] After the above is completed, the device can be fixed on the motor shaft of the grinder by bolts. After starting the grinder, it can drive the rotation of the adjustment handle, the connecting column, the cross plate, the connecting part, the plug plate, the first polishing disc and the second polishing disc, so that the first polishing disc can rub against the surface of the workpiece;

[0033] After the grinding surface of the first polishing surface is worn, the positioning column can be pulled out and the connecting column can be rotated to disengage the connecting column from the connecting tube. At this time, the fan-shaped column can be separated, so that the plug plate can be pulled out of the slot. After the positioning of the plug plate is lost, the first polishing disc and the second polishing disc can be separated. After the two are replaced, the plug plate can be inserted into the slot again to fix the first polishing disc and the second polishing disc again, and the connecting column can be threadedly connected to the connecting tube again, so that subsequent grinding and polishing operations can be performed through the second polishing disc, avoiding affecting the progress of work.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
