At this point, threaded end 912 of pressure gauge 914 may be clamped inside threaded end attachment region 925. Due to the fact that the threads in the threaded end assembling area 925 are matched with the threads on the threaded end 912, certain clamping force and sealing effect are achieved between the threaded end assembling area and the threaded end, and therefore the instrument can be clamped without manual operation.

In addition, the device also comprises an oil pipe 911, one end of which is connected with the quick connection rod 94 through the cylinder bracket 97 and is communicated with the air passage, and the other end of which is positioned outside the cylinder bracket 97.

The pressure generating device 12 comprises a vacuum pump 120, a booster 121, a front electromagnetic valve 122, a positive pressure cavity 123, an oil tank 124, a rear electromagnetic valve 125 and a pressure output end 126 which are sequentially communicated through an air path, a pressure sensor 1231 is arranged inside the pressure cavity 123, the controller 13 is respectively and electrically connected with the vacuum pump 120, the booster 121, the front electromagnetic valve 122, the pressure sensor 1231 and the rear electromagnetic valve 125, and the pressure output end 126 is connected with an oil pipe 911 in a pressure instrument quick-connection assembly and is communicated with the air path.

The front solenoid valve 122 may be a pneumatic solenoid valve, and the rear solenoid valve 125 may be a two-position three-way solenoid valve including a working port a, a working port b, and a working port c. When the working port a and the working port b in the post-solenoid valve 125 communicate with each other, the pressure medium output through the post-solenoid valve can be input into the pressure output terminal 126 at the end thereof; when the working port a and the working port c in the post-solenoid valve 125 communicate, the pressure medium output through the post-solenoid valve is discharged to the outside of the body.

The controller operates the pre-solenoid 122 to an open state and the working ports a and b in the post-solenoid 125 are communicated.

The controller controls the vacuum pump to generate a corresponding preset air pressure, and then the air pressure is input into the supercharger 121. The controller controls the pressure booster 121 to boost the preset air pressure, and the preset air pressure is input into the positive pressure cavity 123 through the preposed electromagnetic valve 122.

The pressure sensor 1231 collects a pressure electrical signal inside the positive pressure chamber 123, and inputs the collected pressure electrical signal into the controller 13, so that the controller processes the current pressure value. And the controller receives the pressure electric signal and then processes the pressure electric signal to acquire a corresponding pressure value. When the pressure value reaches the pressure value specified by the controller, the controller controls the vacuum pump to stop the pressure generating operation, controls the supercharger to stop the supercharging operation and controls the front electromagnetic valve to be switched to a closed state. In addition, when the vacuum pump and the pressure booster are in a stop state and the front electromagnetic valve is in a closed state, the pressure sensor 1231 still collects the pressure electric signal in the positive pressure cavity 123 in real time or in a stage, and inputs the pressure electric signal into the controller. And if the controller judges that the pressure value is less than the specified pressure value, the controller controls the vacuum pump to perform pressure making operation, controls the supercharger to perform supercharging operation, and controls the front electromagnetic valve to be changed into an open state.

The pressure in the positive pressure chamber 123 is input into the oil tank 124, so that the liquid in the oil tank 124 is delivered to the position of the pressure output end 126 through the post-positioned solenoid valve 125 and is input into an oil pipe 911 connected with the pressure output end 126 and in air path communication, and is finally input into a pressure meter 914 mounted on the meter quick-connect assembly 9.

At least a part of the outer wall surface of the oil tank 124 is a transparent region. The transparent area corresponds to the oil amount observation window 15 provided on the working face a 161. Since the position of the oil amount observation window 15 corresponds to the position of the transparent area and is directed toward the operator, the amount of liquid stored in the oil tank 124 can be checked through the oil amount observation window 15, thereby replenishing the liquid in the oil tank in time.
