The slider 1506 drives the second rack 1505 to move downward, and the second rack 1505 engages with the gear 1504 to move the first rack 1501 upward.

[0088] The oil injection lubrication mechanism 16 is provided to lubricate the second circular shaft 1401 to reduce wear, thereby preventing the gap between the support rod 2 and the bottom rod 3 from being too large and affecting stability.

[0089] The specific operation of the oil injection lubrication mechanism 16 is as follows: during the movement of the first rack 1501, the push seat 1503 at the top of the first rack 1501 approaches the movable plate 1601 until the two are in contact, and then the first rack 1501 continues to move upward until the first rack 1501 completes the movement, pushing the movable plate 1601 to move 1-2CM, and the movable plate 1601 drives the trapezoidal block 1605 to move through the movable rod 1604, and at the same time compresses the second spring 1603, and the trapezoidal block 1605 The two side walls squeeze the inclined surfaces of the two wedge blocks 1606 respectively, so that the two wedge blocks 1606 move away from each other, and at the same time compress the third spring 1609, and the wedge block 1606 drives the piston 1611 to move through the push rod 1612, and the piston 1611 squeezes the lubricating oil in the inner cavity 1610, so that the lubricating oil enters the delivery channel 1613 through the oil outlet one-way valve 1615, and then is diverted to a plurality of oil outlet holes 1614 to provide lubrication for the second circular shaft 1401.

[0090] During the movement of the first rack 1501, the push seat 1503 separates from the movable plate 1601, and the movable plate 1601 is reset by the compression force of the second spring 1603. The movable plate 1601 drives the trapezoidal block 1605 to reset through the movable rod 1604, and the wedge block 1606 is reset by the elastic force of the third spring 1609. The wedge block 1606 drives the piston 1611 to reset through the push rod 1612, and the inner cavity 1610 is sucked, so that the lubricating oil stored in the oil storage box 1607 enters the inner cavity 1610 through the oil inlet one-way valve and the oil pipe 1608, so as to replenish the lubricating oil for the inner cavity 1610.

[0091] Through the above design, automatic lubrication is achieved.

[0092] In a specific implementation, the oil storage box 1607 is provided with a refueling port, which extends to the outer wall of the bottom rod 3. At the same time, a sealing plug is provided at the refueling port. When refueling the oil storage box 1607, the sealing plug is removed.
