[0022] For example, see below. Figures 1 to 9 As shown, a handheld steering arm calibration device includes a handheld rod 10, and a circular detection block 20 is fixed to the bottom end of the handheld rod 10.

[0023] The circular detection block 20 has multiple inwardly radially extending detection holes 21 formed on its annular outer wall, and a downwardly extending central hole 22 formed in the middle of its top surface. The inner ends of all detection holes 21 are connected to the central hole 22.

[0024] The circular detection block 20 has two inwardly extending observation grooves 23 formed on its sidewall. A detection hole 21 is formed on the annular outer sidewall of the circular detection block 20 on both the left and right sides of the observation grooves 23. The inner sidewall of the observation groove 23 is arc-shaped.

[0025] The circular detection block 20 has an upwardly extending threaded post 24 formed in the center of its top surface. The top end of the central hole 22 extends out of the top surface of the threaded post 24. The handheld rod 10 has a central through hole formed in its center, and an internal thread is formed on the inner sidewall of the bottom end of the central through hole. The upper part of the threaded post 24 is threaded onto the internal thread at the bottom of the central through hole of the handheld rod 10. The handheld rod 10 and the threaded post 24 are detachable for easy assembly and disassembly.

[0026] Furthermore, the inner wall of the top end of the central hole 22 is formed with an internal thread, the bottom of the vent connector 1 is screwed onto the internal thread at the top end of the central hole 22 and communicates with the central hole 22, and the vent connector 1 is inserted into the central through hole of the handheld rod 10.

[0027] Furthermore, the circular detection block 20 has an upwardly extending weight-reducing groove 25 formed in the center of its bottom surface.

[0028] The circular detection block 20 has a downward-extending arc-shaped groove 26 formed on one side of its top surface, which communicates with the weight-reducing groove 25. The circular detection block 20 allows observation of the area below through the arc-shaped groove 26.

[0029] Furthermore, the circular detection block 20 has an internal cavity 29 formed inside, and the central hole 22 and the detection hole 21 communicate with the internal cavity 29.

[0030] The bottom surface of the radially extending edge formed on the middle outer side wall of the vent connector 1 presses against the top surface of the threaded post 24.

[0031] In this embodiment, when in use, one end of the venting connection pipe is connected to the top of the venting connector 1, and the other end of the venting connection pipe is connected to the outlet of the air source (such as the outlet of the air tank) and the outlet of the control valve. A pressure sensor or pressure gauge is installed on the connection pipe, and its detection head extends into the connection pipe. If a pressure sensor is used, it needs to be electrically connected to the control host through an electrical connection wire. The detected pressure data is displayed on the display screen connected to the control host.

[0032] Then, open the control valve to allow airflow. The pressure value will then be displayed on the screen or pressure gauge. Next, holding the handheld rod 10, insert the circular detection block 20 into the mounting hole on the forearm. Figure 5As shown, its bottom surface presses against the top surface of the radially extending edge formed on the inner sidewall of the middle part of the mounting hole. The outer sidewall of the circular detection block 20 is close to the inner sidewall of the mounting hole. Observe the pressure value displayed on the display screen or pressure gauge. If the value increases and reaches or even exceeds the set value, it indicates that the machining accuracy of this mounting hole meets the requirements. (The first step is that the circular detection block 20 can be inserted into the mounting hole at the forearm, indicating that it meets the installation requirements. The outer sidewall of the circular detection block 20 matches the inner sidewall of the mounting hole at the forearm. The second step is that the inner sidewall of the mounting hole covers the corresponding detection hole 21. The closer it is, the greater the obstruction to the exhaust of the detection hole 21, which makes it more difficult for air to pass through the connecting pipe, and the pressure will increase. Observe that the pressure value displayed on the display screen or pressure gauge will be larger. When its value is greater than the specified value, it indicates that its accuracy meets the requirements.)

[0033] Then, the circular detection block 20 can be removed and inserted into the arm, as shown. Figure 6 and 9 As shown, it is necessary to test the four arc-shaped wall surfaces 100 on the top inner sidewall of the mounting groove. The lower inner sidewall of each of the four arc-shaped wall surfaces 100 has a radial extension. The bottom surface of the circular detection block 20 presses against the top surface of the radial extension. The annular outer sidewall of the circular detection block 20 is close to the corresponding arc-shaped wall surface 100. Rotate the circular detection block 20 so that the outer end of the detection hole 21 is close to the corresponding arc-shaped wall surface 100. Observe the pressure value displayed on the display screen or pressure gauge. When the value is greater than the specified value, it means that its accuracy meets the requirements.

[0034] Its detection is convenient, effective, and efficient.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
