The claw 28 contacts a lever 31, and the lever 31 is fixed to the start box body 29 through a fixed shaft 30, and the start box body 29 is fixed to the right end of the fixed sleeve 1, wherein a limit block 37 is also provided below the left end of the lever 31; a foot pedal 33 is fixed to the right side of the lever 31, and the right end of the lever 31 is connected to the start box body 29 through a tension spring 32; a spring fixing sleeve 34 is provided below the support block 27, and the spring fixing sleeve 34 is fixed to the inner bottom wall of the fixed sleeve 1, and a spring 2 35 is provided in the spring fixing sleeve 34, and a shock absorbing block 36 is provided at the top of the spring 2 35, and the lower end of the shock absorbing block 36 is inserted into the spring fixing sleeve 34;

[0024] The material of the shock-absorbing block 36 is elastic rubber.

[0025] In this embodiment, when it is necessary to quantitatively fill the pressure container 9, first, the foot pedal 33 is slowly stepped on with the foot. During the stepping process, the left end of the lever 31 will slowly rise, and under the gravity of the counterweight block 14, the counterweight block 14 will drive the lifting rod 12, the lifting seat 2, the support block 27 and the pawl 28 to move upward; during the upward movement of the lifting seat 2, the push rod 6 will extend to the inner side of the lifting seat 2 under the squeezing action of the cam block 3, and the extended push rod 6 will position and fix the pressure container 9; at this time, continue to step on the foot pedal 33 until the pawl 28 is separated from the lever 31 , the pawl 28 rises to the top of the lever 31, and the lever 31 returns to its original position under the dual action of the tension spring 32 and the limit block 37; at the same time, the pressure container 9 moves upward with the lifting seat 2 until the delivery push rod 23 is tightly pressed against the one-way valve 10 on the pressure container 9, and the upper end of the delivery push rod 23 is also tightly pressed against the one-way valve 22. Under the action of the delivery push rod 23, the one-way valve 10 and the one-way valve 22 are both in the connected state, and the high-pressure fluid will enter the fluid delivery pipeline 21, the one-way valve 22, the delivery push rod 23 and the one-way valve 10 through the fluid delivery pipeline. In the pressure container 9, when the high-pressure fluid filled in the pressure container 9 reaches a certain weight, the pressure container 9 and the lifting seat 2 and other components below it will reach a weight balance with the counterweight block 14, and the weight of the quantitative filling can be adjusted by replacing the weight of the counterweight block 14; at this time, the pressure container 9 and the lifting seat 2 will descend and return to their original positions. During the descent, the pawl 28 will contact the lever 31. Under the pressure of the lever 31, the pawl 28 will retract into the support block 27, thereby smoothly reaching the bottom of the lever 31. When the support block 27 returns to its original position, it will contact the shock-absorbing block 3 6, under the action of the shock-absorbing block 36 and the spring 2 35, the lifting seat 2 and the pressure container 9 will slowly slow down until they stop. At this time, under the action of the spring 1 7, the push rod 6 no longer fixes the pressure container 9, and the pressure container 9 can be taken away. After the pressure container 9 is taken away, under the action of the counterweight block 14, the support block 27 and the lifting seat 2 will move upward until the pawl 28 contacts the lever 31. At this time, the lever 31 returns the support block 27 and the lifting seat 2 to the starting position through the pawl 28. At this time, the next pressure container 9 can be placed on the lifting seat 2 to wait for filling.
