[0036] Referring to Figures 3-5The bottom end of the plug 9 is fixedly connected with one end of the moving spring 10, and the other end of the moving spring 10 is fixedly connected with the inner wall of the top end of the moving rod 7. When the plug 9 moves downward, the moving spring 10 is compressed. When reset, the plug 9 is reset by the elastic force of the moving spring 10. The outer wall of the extrusion block 8 is in contact with the outer wall of the triangular block 3. The extrusion block 8 is provided with two groups. When the extrusion block 8 extrudes the triangular block 3, the two groups of triangular blocks 3 are close to each other. The fixed column 5 penetrates and is slidingly connected to the inner wall of the workbench 2. The workbench 2 is provided with a notch corresponding to the fixed column 5, so that the fixed column 5 can move forward and backward. The moving rod 7 penetrates and is slidingly connected to the inner wall of the workbench 2. The workbench 2 is provided with a notch corresponding to the moving rod 7, so that the moving rod 7 can move left and right. The plug 9 is slidingly connected to the inner wall of the moving rod 7.

The plug 9 moves the moving rod 7 and the extrusion block 8 to the right. With the extrusion block 8 no longer in contact with the triangular block 3, the two groups of triangular blocks 3 move away from each other under the elastic force of the movable spring 4. The triangular blocks 3 move away from each other with the positioning plate 6, releasing the positioning of the wear plate. At this time, the hand releases the plug 9, and the plug 9 is inserted into the notch of the workbench 2, completing the positioning of the positioning plate 6. If the wear plate needs to be positioned again, the above operation steps can be repeated.

[0039] When the positioning plate 6 needs to be disassembled, the hand extrudes the clamping block 11, the two sets of clamping blocks 11 are close to each other and extrude the positioning spring 12, when the clamping block 11 is separated from the notch on the positioning plate 6, the hand takes out the positioning plate 6, then the hand releases the clamping block 11, the two sets of clamping blocks 11 are separated from each other by the elastic force of the positioning spring 12, when the positioning plate 6 needs to be installed, the hand presses the clamping block 11, when the clamping block 11 does not shield the positioning plate 6, the hand aligns and inserts the positioning plate 6 on the fixed column 5, the hand releases the clamping block 11, and the clamping block 11 is clamped into the notch of the positioning plate 6, the limiting of the positioning plate 6 is completed, if the positioning plate 6 needs to be replaced again, the above operation steps can be repeated.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. that is made within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
