The front side of the shell 2 is provided with two oil injection holes, and liquid is discharged therefrom when under pressure. The outer front side of the shell 2 is fixedly connected to two oil injection nozzles, which receive the liquid inside the holes and discharge it. The outer right side of the vacuum booster 1 is fixedly connected to a sealing sleeve 20 to further enhance the airtightness. The top of the shell 2 is provided with a liquid inlet hole 1 3, and the top of the shell 2 is provided with a liquid inlet hole 2 4, which is the source of the liquid inlet of the device. The top of the shell 2 is fixedly connected to two butt pipes 5, and the tops of the two butt pipes 5 are fixedly connected to a liquid storage tank 21. The top of the liquid storage tank 21 is threadedly connected to a tank cover 22 for storing the required liquid. The shell 2 The right side of the interior is fixedly connected with a sealing plug 6, and the interior of the sealing plug 6 is slidably connected with a push rod 7, which converts the force transmitted by the foot pedal into the force of the linear motion of the push rod 7. The left side of the exterior of the push rod 7 is threadedly connected with a screw rod 8, and the exterior of the screw rod 8 is threadedly connected with an extension rod 9, which can adjust the length of the internal structure as needed. The exterior of the extension rod 9 is fixedly connected with two pistons 10, and the exteriors of the two pistons 10 are in contact with the inner wall of the outer shell 2, and the exterior of the piston 2 11 is in contact with the inner wall of the outer shell 2 to create a closed environment. The exterior of the push rod 7 is fixedly connected with a piston 2 11, and the exterior of the extension rod 9 and the exterior of the push rod 7 are sleeved with an elastic component, so that the push rod 7 can automatically reset when no force is applied. The elastic component includes a spring 12 and a spring 2 13. The spring 12 is sleeved on the exterior of the extension rod 9, and the spring 2 13 is sleeved on the exterior of the push rod 7;

[0024] One end of spring 12 is fixedly connected to the outer side of one of the pistons 10, and the other end of spring 12 is fixedly connected to the left side of the inner wall of the outer shell 2. One end of spring 2 13 is fixedly connected to the outer side of another piston 10, and the other end of spring 2 13 is fixedly connected to the outer side of piston 2 11.

[0025] Reference Figure 1 , Figure 3The interior of the fixed plate 14 is rotatably connected to a rotating shaft 15, the exterior of the rotating shaft 15 is rotatably connected to a foot pedal 16, a flat hole 17 is provided in the middle of the foot pedal 16, the right side of the exterior of the push rod 7 is fixedly connected to a connecting block 18, the right side of the connecting block 18 is fixedly connected to a connecting rod 19, the exterior of the connecting rod 19 is movably connected to the interior of the flat hole 17, and the exterior of the connecting rod 19 contacts the inner wall of the foot pedal 16.

[0026] Compared with some devices in the prior art, the above content controls the movement of the push rod 7 so that the push rod 7 and the extension rod 9 move inside the shell 2. Due to the close contact between the piston and the inner wall of the shell 2, the movement of the piston can change the pressure changes inside the two chambers, thereby causing the liquid discharge nozzle to change the structure connected by the pipeline. Under the action of the double chambers, better braking effect is achieved.

[0027] Working principle: The user starts the operation by stepping on the foot pedal 16 on the fixed plate 14. The movement of the foot pedal 16 is transmitted to the connecting rod 19 through the rotating shaft 15. The connecting rod 19 is connected to the push rod 7 through the flat hole 17, and the rotational movement of the foot pedal 16 is converted into the linear movement of the push rod 7. The linear movement of the push rod 7 is pushed forward, driving the screw rod 8 and the extension rod 9 threadedly connected thereto to move together.

[0028] The movement of the extension rod 9 causes the two pistons 10 fixed outside it and the piston 2 11 outside the push rod 7 to slide along the inner wall inside the shell 2. The close contact between these pistons and the inner wall of the shell 2 forms a closed environment, effectively dividing the internal space of the shell 2 into independent pressure chambers. The movement of the pistons changes the volume of these chambers, thereby causing the pressure change of the internal liquid. This pressure change pushes the liquid to move toward the injection hole and is discharged through the injection nozzle. At the same time, the liquid inlet hole 1 3 and the liquid inlet hole 2 4 on the top of the shell 2 allow new liquid to be added from the liquid storage tank 21 to the interior through the docking pipe 5 to maintain the continuous operation of the system.

[0029] After the operation is completed, the elastic component causes the piston and the push rod 7 to automatically return to the initial position. The spring 12 and the spring 2 13 are respectively fixed to the corresponding positions of the piston 10 and the piston 2 11 and the housing 2 to ensure that the push rod 7 and the extension rod 9 can return to the initial state after the force is removed.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
