[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a combined diamond grinding wheel, comprising an inner base 1, an outer grinding wheel 2 and a connecting handle 3.

[0022] The upper side of the inner base 1 is plugged into the outer grinding wheel 2 through the positioning block 11, and the upper side of the inner base 1 is connected to a connecting handle 3, and a threaded layer 31 is provided on the outer side of the connecting handle 3. The bottom of the connecting handle 3 is threadedly connected to a threaded adjustment sleeve 41 through the threaded layer 31, and a rotating handle 42 is installed on one side of the threaded adjustment sleeve 41. The bottom of the threaded adjustment sleeve 41 is connected to an extrusion block 43, and a support seat 46 is installed inside the inner base 1, and the outer side of the support seat 46 is connected to a plug-in block 45 through a reset spring 44.

The side of the plug-in block 45 away from the support seat 46 is plugged into the groove inside the outer grinding wheel 2. The inside of the rotating handle 42 is threadedly connected to the threaded limit pin 48. The extrusion block 43 is inclined on all sides. The side of the plug-in block 45 close to the extrusion block 43 is arc-shaped. A plug-in groove for plugging with the support seat 46 is opened inside the extrusion block 43.

[0024] During specific implementation, in order to facilitate the carrying and quick replacement of the grinding wheel, the grinding wheel is set as a whole in the form of an inner base 1 and an outer grinding wheel 2. When different grinding wheels are needed, a suitable outer grinding wheel 2 is selected and placed on the upper side of a neat plane. The positioning block 11 of the inner base 1 is aligned with the positioning groove on the upper side of the outer grinding wheel 2 through the connecting handle 3 and then plugged into the outer grinding wheel 2. The threaded adjustment sleeve 41 is pushed by rotating the handle 42, and the threads inside the threaded adjustment sleeve 41 and the threads on the outer side of the connecting handle 3 are moved downward by threading until the bottom of the extrusion block 43 abuts against the arc layer of the plug-in block 45 through the inclined layer, and the plug-in block 45 is squeezed outward until the outer side of the plug-in block 45 is plugged into the reserved groove inside the outer grinding wheel 2. The threaded limiting pin 48 inside the rotating handle 42 is limited by the threaded limiting groove on the upper side of the inner base 1 to complete the quick installation of the outer grinding wheel 2.

[0025] When disassembling, first open the threaded limit pin 48 through the action of the thread, rotate the rotating handle 42 in the opposite direction, and after adjusting the threaded adjustment sleeve 41 back to its original position, the plug-in block 45 is reset under the action of the reset spring 44 and the magnetic block 47. At this time, the plug-in block 45 is located inside the inner base 1 and is no longer plugged into the outer grinding wheel 2. The support seat 46 is used to provide support and limiting effects for the extrusion block 43 to prevent the extrusion block 43 from moving downward excessively to squeeze the reset spring 44, causing the reset spring 44 to deform and affecting the reset effect of the reset spring 44. The combined diamond grinding wheel can quickly complete the replacement of the outer grinding wheel 2 by rotating the threaded adjustment sleeve 41, so that the outer grinding wheel 2 is easy to replace quickly, and there is no need to carry the completed grinding wheel during work, which is convenient to carry.

The top of the support ring 55 is slidably connected to the sliding connection groove inside the adjusting screw sleeve 56 through a sliding connection layer. The interior of the adjusting screw sleeve 56 is threadedly connected to the connecting handle 3, and a rotating block 57 is connected to one side of the adjusting screw sleeve 56.

[0027] When the inner grinding wheel 51 is pushed out of the bottom of the inner base 1, the inner grinding wheel 51 can be used to finely grind the arc and other parts. The upper side of the support ring 55 is slidably connected to the sliding connection groove inside the adjusting screw sleeve 56 through the sliding connection layer to avoid affecting the fine grinding mechanism 5 when the adjusting screw sleeve 56 rotates. The combined diamond grinding wheel is provided with a fine grinding mechanism 5, which can grind the grooves that the outer grinding wheel 2 cannot grind, and the operation is flexible and convenient.

[0028] To sum up, when using the combined diamond grinding wheel, select a suitable outer grinding wheel 2, align the positioning block 11 of the inner base 1 with the positioning groove on the upper side of the outer grinding wheel 2 through the connecting handle 3, and then plug it into the outer grinding wheel 2. Push the threaded adjustment sleeve 41 by rotating the handle 42 to drive the bottom of the extrusion block 43 to abut against the arc layer of the plug-in block 45 through the inclined layer, and squeeze the plug-in block 45 outward until the outer side of the plug-in block 45 is plugged into the reserved groove inside the outer grinding wheel 2.
