8. The method of using a drop test apparatus for an electromagnetic hob according to claims 1 to 7, characterized in that: The method comprises the following steps: S1, First, the electromagnetic cooker to be tested is placed on the numerical control conveying belt (2), and then moved between the clamping rods (87), while the numerical control cylinder (83) is started to pull the trapezoidal block (84) backward. When the trapezoidal block (84) is pulled, the two triangular blocks (85) slide along the inclined surface of the trapezoidal block (84), and the triangular blocks (85) slide inward in the sliding plate (82), and the two clamping rods (87) slide inward at the same time, and the electromagnetic cooker to be tested is clamped, and then the driving motor (52) is started to drive the rotating disc (53) to rotate, and the connecting rod (55) at the lower end is rotated, and the sliding rod (58) at the lower end is rotated, and the other end of the sliding rod (58) is driven to slide up and down in the sliding groove (54); S2, But when the driving motor (52) rotates for the first time, the moving sliding groove (59) slides upward to drive the spline rod (61) to slide upward at the same time, the spline rod (61) drives the surface of the telescopic rod (62) to slide upward in the Y-shaped groove (72), the hook (63) on the side of the telescopic rod (62) first contacts and presses the one-way pawl (710), and rotates inward, and is blocked by the baffle (73) when sliding to the middle of the Y-shaped groove (72), and the telescopic rod (62) slides along the inclined surface to the branch of the Y-shaped groove (72), the telescopic rod (62) slides along the surface of the spline rod (61) and is clamped, and the connecting rod (55) still needs to continue to rotate at the same time, the telescopic rod (62) and the spline rod (61) drive the sliding rod (58) to slide in the vertical sliding groove (56) in the connecting rod (55) through the moving sliding groove (59), and press the spring (57), so that the sliding radius of the sliding rod (58) is shortened, and the connecting rod (55) continues to rotate; S3, when the connecting rod (55) rotates downward and is about to complete the first week, the telescopic rod (62) is also sliding downward in the Y-shaped groove (72) with the telescopic rod (62), and the spline rod (61) is reset by the spring (57), and when passing through the one-way pawl (710), the reverse hook (63) engages with the one-way pawl (710), driving the one-way pawl (710) to slide downward, the one-way pawl (710) drives the sliding rod (79) to slide downward in the spline groove (78), and the sliding rod (79) simultaneously drives the connecting rod (76) to slide downward in the inclined groove (77), until the one-way pawl (710) and the reverse hook (63) are disengaged, the connecting rod (76) slides downward, driving the arc-shaped sliding block (75) to slide in the arc-shaped sliding groove (74), and the arc-shaped sliding block (75) drives the baffle (73) to rotate, so that the baffle (73) is opened, so that the connecting rod (55) rotates the second week, driving the telescopic rod (62) to slide to the top of the Y-shaped groove (72), so that two different heights can be tested, and when the telescopic rod (62) slides upward, it passes through the guide groove (712), so that the telescopic rod (62) is extended, and when the telescopic rod (62) slides downward, the reverse hook (64) on the side of the telescopic rod (62) is pressed against the one-way pawl (711), and at the third week, the one-way pawl (711) is engaged, driving the one-way pawl (711) to slide upward, the one-way pawl (711) drives the sliding rod (79) to slide upward in the spline groove (78), and the sliding rod (79) simultaneously drives the connecting rod (76) to slide upward in the inclined groove (77), until the one-way pawl (711) is disengaged through the reset groove (713) and the reverse hook (64), the connecting rod (76) slides upward, driving the arc-shaped sliding block (75) to slide in the arc-shaped sliding groove (74), and the arc-shaped sliding block (75) drives the baffle (73) to rotate, so that the baffle (73) is closed, and the cycle is repeated; S4, at the same time, when the spline rod (61) slides back and forth, the fixed ring (67) slides, the fixed ring (67) drives the sleeve (68) to slide on the surface of the fixed rod (65), the driving motor (52) rotates the sleeve (68) by one week, and the clamping mechanism (8) slides along the trajectory of the turning groove (66) on the surface of the fixed rod (65) to the middle, and then rotates by ninety degrees on the turning groove (66) through the fixed ring (67), until it slides to the middle of the fixed rod (65), and then the numerical control cylinder (83) controls the clamping rod (87) to release the electromagnetic stove sample, so that it is free falling, and tests its strength, and the numerical control cylinder (83) controls the clamping rod (87) to clamp the second sample again when the driving motor (52) rotates back and forth by one week, and tests higher height, and the cycle is repeated.
