The invention specifically uses the flow and the working principle:

when the second sliding part 21 is not used, the second sliding part 21 moves downwards to drive the third sliding part 22 to move downwards, the third sliding part 22 moves downwards to drive the fourth spring 23 to compress, when the second sliding part 21 moves downwards, the flush inclined surface is tangent to the first sliding part 19, the first sliding part 19 moves along the inclined surface of the second sliding part 21, the second sliding part 21 continues to press downwards to drive the first sliding part 19 to move, the first sliding part 19 moves to drive the third spring 18 to compress, and when the first sliding part 19 moves to the range of the first sliding groove 16, the second spring 13 resets to drive the second plate 12 to move, the second plate 12 moves to drive the first supporting part 11 to move upwards, and the first supporting part 11 loses the supporting effect on the first plate 8.

Because hydraulic jack 2 is in the horizontality in actuating mechanism 3 when not using, lead to first warning board 24 can't upwards slide, again because third dead slot 25 communicates with each other with first dead slot 7, lead to gaseous inflation in first dead slot 7 simultaneously, gaseous inflation in third dead slot 25, gaseous inflation leads to first plate 8 upward movement, first plate 8 upward movement drives first spring 9 and compresses, staff's accessible first display slot 62 sees whether first plate 8 is in the usable position.

When a user needs to use the hydraulic jack 2, the first supporting member 11 is pressed downwards, the first supporting member 11 moves downwards to drive the second plate 12 to move, the second plate 12 moves to drive, and the second spring 13 is stretched. Meanwhile, the first support 11 brings the first connecting member 15 to move downwards when moving downwards. The downward movement of the first connecting member 15 causes the downward movement of the first sliding member 19. When the first slide 19 moves to the point where the second runner 20 communicates with the first runner 16. The third spring 18 returns to move the first sliding member 19 outward to complete the fixing of the first support 11. At this time, the first supporting member 11 contacts with the upper surface of the first plate 8, when the gas in the third empty slot 25 expands again, the first plate 8 cannot move upward due to the support of the first supporting member 11, and at this time, the first warning plate 24 in the third empty slot 25 in the first empty slot 7 moves upward.

When the hydraulic jack 2 is used, the first driving rod 28 is pressed back and forth, the first driving rod 28 moves, and the first driving rod 28 moves to drive the first transmission column 30 to reciprocate. The first transmission column 30 moves to rub with the third sliding groove 29 to generate heat, so that the temperature in the third hollow groove 25 rises, the gas expands, and the first warning plate 24 is driven to move upwards by the expansion of the gas at the moment, because the first plate 8 is supported by the first supporting column 26 and cannot move. When the first warning plate 24 moves upward, it will contact the first driving rod 28, and when the user feels the change of the hand feeling, he will know that the oil pressure temperature in the hydraulic jack 2 is not suitable for using the hydraulic jack 2 again.

When the hydraulic jack 2 is used, the third supporting column 36 is enabled to completely support the required object through the third supporting column 36 by the internal mechanism of the hydraulic jack 2, and the second supporting piece 42 is adjusted to enable the first rotating wheel 52 to be in contact with the third supporting column 36 after the support is completed. By adjusting the second transmission rod 60, the second transmission rod 60 moves to reduce the distance between the first transmission rod 55 and the fourth plate 57, and the fifth spring 58 is reset. The fifth spring 58 is reset to drive the first transmission rod 55 to move, and the first transmission rod 55 moves to drive the first pawl 54 to be tangent with the first gear 53, so as to clamp the first gear 53.

The first gear 53 cannot move while the first rotating wheel 52 cannot move. When the temperature rises, the oil pressure in the hydraulic jack 2 changes, causing the density of the liquid to decrease, thereby decreasing the supporting force of the third supporting column 36 on the desired object. The third support column 36 slides down. Because the first rotating wheel 52 is in contact with the third supporting column 36, a certain supporting force will be provided to the third supporting column 36. When the first rotating wheel 52 provides a supporting force for the third supporting pillar 36, which is not enough to prevent it from sliding downwards, the first rotating wheel 52 drives the second supporting member 42 to move downwards, the second supporting member 42 drives the second connecting member 41 to move downwards, and the second connecting member 41 drives the second cylinder 40 to slide in the first sliding groove 39. The second cylinder 40 moves to drive the first transmission member 47, and the first transmission member 47 moves to drive the third cylinder 48. When the third cylinder 48 moves, the gas in the first pipe groove 49 rises, and the gas pressure rises. When the air pressure in the first pipe groove 49 rises, the air pressure in the second pipe groove 50 communicated with the first pipe groove rises to drive the first indication post 51 to move upwards, so that the user is reminded that the supporting force provided by the second supporting part 42 can not effectively support the third supporting post 36, and the use is recommended to be stopped immediately.

After the use, the second transmission rod 60 is adjusted to increase the distance between the fourth plate 57 and the first transmission rod 55, and at the same time, the first transmission rod 55 is supported, the first transmission rod 55 moves to drive, the fifth spring 58 stretches, and drives the first pawl 54 to be away from the first gear 53, at this time, the first rotation wheel 52 can rotate, and the third support pillar 36 can complete free lifting.
