[0015] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 4It is given, including a left and right axial power shaft 1, a grinding wheel 2 is coaxially mounted on the power shaft 1, a plurality of fixing grooves 3 opening outward and in left and right directions are provided at the right end of the power shaft 1, a receiving groove 4 is coaxially provided in the power shaft 1, a plurality of fixing blocks 5 corresponding to the fixing grooves 3 are slidably connected in the receiving groove 4, the upper end of the fixing block 5 is inserted into the fixing groove 3 and the upper end surface is an inclined surface with the left side higher and the right side lower, a yield groove 6 is provided at the lower end of the fixing block 5, a guide groove 7 connected to the yield groove 6 is provided on the fixing block 5, a plurality of moving rods 8 corresponding to the fixing block 5 and movable left and right are provided in the receiving groove 4, the moving rod 8 is inserted into the corresponding yield groove 6 and is provided with a plug 9 inserted into the guide groove 7, and a plurality of assembly blocks 10 corresponding to the fixing groove 3 and insertable into the fixing groove 3 are provided on the inner side of the grinding wheel 2.

[0017] In order to move the moving rod 8 left and right, a moving plate 11 located on the right side of the fixed block 5 and fixed to the moving rod 8 is coaxially slidably connected in the accommodating groove 4, and a connecting column 12 penetrating the power shaft 1 is coaxially provided at the right end of the moving plate 11.

[0018] In order to facilitate pressing the connecting column 12 , a pressing plate 13 is coaxially disposed at the right end of the connecting column 12 .

[0019] In order to facilitate the resetting of the moving plate 11 , a tension spring 14 is sleeved on the connecting column 12 , and the left end of the tension spring 14 is fixed to the moving plate 11 and the right end is fixed to the power shaft 1 .

[0020] For ease of use, the guide groove 7 is an inclined groove with the left side higher and the right side lower.

[0021] When the utility model is in use, the power shaft 1 is first connected to the power source. When the power source is started, the power shaft 1 is driven to rotate, and the power shaft 1 then drives the grinding wheel 2 to rotate through the assembly block 10, and then the grinding wheel 2 is used to work. When the grinding wheel 2 needs to be replaced, the power source is turned off at this time, and then the pressure plate 13 is pressed to the left, and the pressure plate 13 drives the connecting column 12 to move to the left, and the connecting column 12 drives the movable plate 11 to move to the left in the accommodating groove 4, and then drives multiple moving rods 8 to move to the left, and the moving rod 8 drives the plugging column 9 to move to the left in the corresponding guide groove 7, and drives the corresponding fixed block 5 to move toward the middle in the accommodating groove 4. The fixed block 5 moves to the middle for a distance and then retracts into the accommodating groove 4. At this time, the fixed block 5 releases the fixed limit, and at this time, the grinding wheel 2 is moved to the right from the power shaft 1, so that the assembly block 10 moves to the right in the corresponding fixing groove 3. After moving a distance, the grinding wheel 2 is removed from the power shaft 1;

[0022] When the pressure plate 13 drives the connecting column to move to the left, the tension spring 14 is stretched to the left. When the grinding wheel 2 is removed from the power shaft 1, the pressure plate 13 is released. Due to the restoring force of the tension spring 14, the connecting column 12 and the moving rod 8 are driven to move to the right. The moving rod 8 drives the fixed block 5 to move upward through the plug column 9 and the guide groove 7. The fixed block 5 moves upward for a distance and then returns to the initial position. At this time, the unused grinding wheel 2 is re-installed on the power shaft 1, so that multiple assembly blocks 10 are correspondingly inserted into the corresponding fixing grooves 3, and the grinding wheel 2 is pushed to the left. The grinding wheel 2 drives the assembly block 1 0 slides leftward in the fixing groove 3. After sliding to the left for a distance, the assembly block 10 contacts the fixing block 5. Since the upper end surface of the fixing block 5 is an inclined surface, the assembly block 10 presses the fixing block 5 downward. When the assembly block 10 moves leftward to be located to the left of the fixing block 5, the pressing of the fixing block 5 is released. Due to the restoring force of the tension spring 14, the fixing block 5 moves upward to the initial position. At this time, the assembly block 10 is located to the left of the fixing block 5. The fixing block 5 realizes the fixed limit of the assembly block 10, and then realizes the fixed limit of the grinding wheel 2. At this time, the operation can be continued.

[0023] Compared with the prior art, the beneficial effects of the utility model are: the fixed block, assembly block, movable rod, etc. can realize the rapid assembly of the grinding wheel. Compared with the traditional bolt fixed assembly, the operation is simple and time-saving and labor-saving. Only the grinding wheel sleeve is mounted on the power shaft and the grinding wheel is pushed to realize automatic fixed limit. When the grinding wheel needs to be replaced and removed, only the pressure plate is pressed to the left to remove the grinding wheel and replace it, which saves a lot of assembly time. The structure is simple, the concept is novel, the use is convenient, and the practicability is strong.

[0024] It should be pointed out that, according to the needs of implementation, the various components described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.

[0025] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
