[0043] Working principle: When in use, the staff first place the wooden toy inside the template 5, and then use the sander 1 to sand its upper surface.

[0044] Once the upper surface of the wooden toy has been sanded, the staff activates the electric telescopic rod 762, causing the output shaft of the electric telescopic rod 762 to move forward first, and then backward.

[0045] When the output shaft of the electric telescopic rod 762 moves forward, it drives the moving block 763 to move forward, thereby driving the control ball 764 to move forward.

[0046] As the control ball 764 moves forward, its spherical surface pushes the spiral surface of the control groove 75, causing the grooved part of the control groove 75 to be in the same position in the front-back direction. Therefore, when the control groove 75 is subjected to force, it drives the control block 74 to rotate.

[0047] When the control block 74 rotates, it drives the mounting plate 2 4 to rotate synchronously with it. Therefore, the mounting plate 2 4 can rotate to a state where it is in contact with the upper surface of the mounting plate 1 3.

[0048] During the rotation of mounting plate 24, when the inclined surface of the insert 83 is pushed by the edge of the fixing groove 81, the inclined surface is subjected to force, so it squeezes the spring 1 85 and moves towards the fixing plate 84.

[0049] When mounting plate 24 is fully attached to mounting plate 13, insert 83 enters the interior of fixing groove 81 under the elastic force of spring 185.

[0050] Since the front view of the insert 83, the fixing groove 81, the sliding groove 82, etc. are all arc-shaped, it can be ensured that the insert 83 smoothly enters the fixing groove 81 during the rotation of the mounting plate 2 4.

[0051] Subsequently, the moving block 763 moves from front to back under the drive of the electric telescopic rod 762, so the control block 74 is driven to rotate in the opposite direction by the control ball 764, and the principle is the same as before.

[0052] At this time, since mounting plate 3 and mounting plate 4 are fixed by insert block 83, mounting plate 4 rotates in the opposite direction, causing mounting plate 3 to rotate synchronously with it.

[0053] When the lower surface of the mounting plate 24 contacts the upper surface of the processing base 2, the triangular block 861 moves in the direction of entering the mounting plate 24 due to the force on its bottom. Therefore, its inclined surface pushes the push block 862, thereby causing the push block 862 to be pushed by the force to push the insert block 83.

[0054] As the insert 83 moves toward the fixing plate 84 after being subjected to force, it leaves the recessed positions at both ends of the fixing groove 81. Therefore, the fixing relationship between the mounting plate 1 3 and the mounting plate 2 4 is released at this time.

[0055] At this time, the rotating block 72 is reset under the action of the torsion spring 73, which in turn drives the mounting plate 3 to reset. At this time, the wooden toy is in the groove of the template 6 under the action of gravity. Therefore, the wooden toy is flipped over. The sander 1 can be started again to sand the other side of the wooden toy.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
