Adjusting rods 205 are fixedly connected to the same side of each of the two first receiving plates 204. Second receiving plates 203 are slidably connected to the surfaces of both adjusting rods 205. The replacement auxiliary mechanism 2... Mechanism 2, under the action of the auxiliary mechanism 2, can support the grinding wheel 13 when the user needs to replace it. When the user removes the grinding wheel 13, it can support it and lower the grinding wheel 13 stably and safely. When the user needs to install a new grinding wheel 13, it can lift the new grinding wheel 13, thereby facilitating the user's installation. This provides stability when the user installs and removes the grinding wheel 13 and avoids the weight of the grinding wheel 13 affecting the user's convenience when replacing it.

[0025] Reference Figure 4 Mounting blocks 20 are fixedly connected to opposite sides of the two mounting plates 4. A second electric telescopic rod 12 is fixedly installed on the inner wall of the mounting block 20. A push-pull rod 19 is fixedly connected to the telescopic end of the second electric telescopic rod 12. A pressure plate 18 is fixedly connected to the bottom of the push-pull rod 19. The bottom of the pressure plate 18 is in close contact with the top of the first receiving plate 204. A connecting rod 11 is fixedly connected to the inner wall of the connecting plate 202. The surface of the connecting rod 11 is rotatably connected to the inner wall of the first receiving plate 204. By setting the mounting blocks 20, the second electric telescopic rod 12, the push-pull rod 19, the pressure plate 18 and the connecting rod 11 in cooperation, the first receiving plate 204 can be limited when lifting the grinding wheel 13, so that the first receiving plate 204 will not move due to gravity when lifting the grinding wheel 13, thus achieving the purpose of limiting the first receiving plate 204.

[0026] Reference Figure 4 The inner wall of the connecting plate 202 is provided with a U-shaped movable groove 17, and the inner cavity of the U-shaped movable groove 17 is movably connected to the surface of the first receiving plate 204. By setting the U-shaped movable groove 17, space can be provided for the movement of the first receiving plate 204 under the action of the U-shaped movable groove 17, so that the first receiving plate 204 can be stored when not in use.

[0027] Reference Figure 4The inner walls of the two second receiving plates 203 are provided with receiving grooves 14, and the inner cavity of the receiving grooves 14 is in contact with the surface of the grinding wheel 13. By providing the receiving grooves 14, the grinding wheel 13 can be further limited under the action of the receiving grooves 14, so that the grinding wheel 13 can be further limited, thereby increasing the stability and firmness of the grinding wheel 13 when descending or rising.

[0028] Reference Figure 4 The inner wall of the second receiving plate 203 is provided with an adjustment groove 16. The inner cavity of the adjustment groove 16 is slidably connected to the surface of the adjustment rod 205. A push handle 15 is fixedly connected between the two second receiving plates 203 on opposite sides. By setting the adjustment groove 16, the adjustment rod 205 can be moved under the action of the adjustment groove 16, avoiding the situation where the adjustment rod 205 gets stuck when moving, thus achieving the purpose of providing movement space for the adjustment rod 205 when moving.

[0029] Reference Figure 2 and Figure 3 An auxiliary installation ring 6 is fixedly connected to one side of the protective door 9. Four sealing rubber plates 10 are fixedly connected to the inner wall of the auxiliary installation ring 6. The auxiliary installation ring 6 allows users to easily disassemble the fixing nuts of the grinding wheel 13 without opening the protective door 9, thus increasing the convenience of replacing the grinding wheel 13. The sealing rubber plates 10 seal the auxiliary installation ring 6 without affecting its normal use. When the user needs to disassemble and install the fixing nuts of the grinding wheel 13, the user inserts a tool into the auxiliary installation ring 6. Pushing the tool causes the four sealing rubber plates 10 to move, allowing them to separate.

[0030] Reference Figure 2 An electromagnet 7 and an iron plate 8 are fixedly connected to the same side of the protective shell 5 and the protective door 9, respectively. One side of the electromagnet 7 is in close contact with one side of the iron plate 8. By setting the electromagnet 7 and the iron plate 8 to work together, the protective door 9 can be quickly limited and opened, thereby increasing the convenience for users when changing the grinding wheel 13.

[0031] Working Principle: To facilitate easier and more stable replacement of the grinding wheel 13, when the grinding wheel 13 is worn out and needs replacement, the user inserts a tool into the installation auxiliary ring 6. Pushing the tool causes the four sealing rubber plates 10 to move, allowing them to separate. After removing the fixing nuts securing the grinding wheel 13, the user controls the electromagnet 7 via an external power supply and switch, causing the electromagnet 7 to close the attraction to the iron plate 8. Then, the user pulls the handle 15, moving the second receiving plate 203. The moving second receiving plate 203 moves the grinding wheel 13, which is stuck in the receiving groove 14. Simultaneously, the adjusting rod 205 slides in the adjusting groove 16, pulling out the grinding wheel 13. As the grinding wheel 13 moves, it contacts the protective door 9. Opening the protective door 9 via a pivot, and fully pulling out the grinding wheel 13, the user then starts the machine simultaneously via the external power supply and switch. The first electric telescopic rod 201 and the second telescopic rod extend and retract. The telescopic end of the first electric telescopic rod 201 drives the connecting plate 202 to move. The moving connecting plate 202 drives the first receiving plate 204 and the adjusting rod 205 to move, thereby causing the second receiving plate 203 to lower the grinding wheel 13. While the connecting plate 202 is lowering, the telescopic end of the second electric telescopic rod 12 drives the push-pull rod 19 and the pressure plate 18 to lower, so that the pressure plate 18 is always in contact with the first receiving plate 204, providing a stable limit for the first receiving plate 204 when it is lowering, and preventing the first receiving plate 204 from rotating and moving under the influence of the gravity of the grinding wheel 13. After the lower grinding wheel 13 is lowered to a suitable position, the user removes the grinding wheel 13 that needs to be replaced and puts the new grinding wheel 13 into the receiving groove 14. Through the action of the first electric telescopic rod 201 and the second electric telescopic rod 12, the new grinding wheel 13 can be raised and lowered to a suitable position for installation.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
