The limiting sliding groove 23 is four and is cross-distributed relative to the mounting groove 22. The mounting groove 22 is provided with a button 25 which is adapted to the cross section of the mounting groove 22. The circumference of the button 25 is respectively provided with four downward extending vertical plate strips 26. The bottom end of the vertical plate strip 26 is provided with a sliding protruding block 27 which is located in the limiting sliding groove 23. The sliding protruding block 27 slides up and down under the constraint of the limiting sliding groove 23 to realize the constraint of the up and down pressing process of the button 25. The top side of the limiting sliding groove 23 is provided with a blocking strip 24 which limits the upward stroke of the sliding protruding block 27, thereby constraining the highest height of the upward sliding of the button 25 in the mounting groove 22.

[0035] The bottom surface of the button 25 is fixed with a pressing rod 28. The groove bottom of the mounting groove 22 is provided with a via hole for the pressing rod 28 to penetrate. The pressing rod 28 is sleeved with a reset spring. The reset spring is arranged between the button 25 and the groove bottom of the mounting groove 22 to provide an upward elastic force to the button 25.

[0036] The top of the handle 5 of the shell 1 is provided with a giving opening. The contact block 8 is located below the giving opening.

[0037] When the cup cover 3 is buckled at the cup opening, the lower buckle plate 19 is clamped into the arc-shaped clamping groove 20 of the upper buckle plate 18, and when the positioning protruding plate 21 corresponds to the handle 5 up and down, the bottom end of the pressing rod 28 below the button 25 corresponds to the above of the giving opening, realizing that the pressing of the button 25 can press the contact block 8 downward, so that the connecting rod 7 is pressed downward to trigger the micro switch and start the grinding operation. After the button 25 is released, the button 25 is automatically popped up under the action of the reset spring. The connecting rod 7 is up-slid and reset under the lifting action of the built-in spring. The striker rod is separated from the triggering of the micro switch, thereby terminating the grinding operation.

[0038] Based on the above structure, after the cup cover 3 is buckled and locked, the button 25 can be pressed to open the work simply, and the button 25 is lifted to disconnect the power, so that the product will not be overloaded, the motor is effectively protected, the up-down sliding trigger structure of the single connecting rod 7 is more simple, compared with the structure of the existing product which needs multiple connecting rods 7 to cooperate and trigger, it is easier to produce and assemble, the cost is lower, and the operation is more stable.
