The limiting structure includes a support 20, a base plate 21, and a base 22. The base plate 21 and the base 22 are elastically connected. Two support 20s that can approach each other are provided on the top of the base plate 21. The debugging instrument body 10 is clamped and limited by the two support 20s. The base 22 forms a box with an open top. The internal size of the base 22 is larger than the size of the base plate 21. The limiting structure also includes a detection table 23 for placing workpieces. The detection table 23 is fixedly installed on one side of the base 22. The limiting structure also includes an elastic element 24. The elastic element 24 is fixedly installed at the bottom of the base plate 21 and fixedly installed with the base 22. The base plate 21 is elastically connected to the base 22 through the elastic element 24. The elastic element 24 is a tower-shaped spring. The base plate 21 is supported by the elastic element 24, allowing it to float within the support 20. The main body of the test instrument 10 is connected to the handheld digital meter via a connecting cable. The floating base plate 21 can reduce damage to the main body of the test instrument 10 and the instrument connection port caused by the pulling of the wires, and can also reduce damage to the main body of the test instrument 10 caused by external impacts or falls.

[0019] like Figure 4 and Figure 5As shown, the limiting structure also includes a slider 32 and an adjusting screw 33. Two sliders 32 are symmetrically arranged at the bottom of the support 20. The sliders 32 are fixedly installed with the support 20. Two parallel sliding grooves are opened at the top of the base plate 21. The sliders 32 are slidably connected with the sliding grooves. The adjusting screw 33 is rotatably connected with the base plate 21 and threadedly connected with the sliders 32. The sliders 32 form a block with a convex cross section. The sliding grooves are clearance-fitted with the sliders 32. The sliders 32 are fixedly installed with nuts that are adapted to the adjusting screw 33. The adjusting screw 33 is threadedly connected with the nuts. The limiting structure also includes a first clamping groove 30 and a second clamping groove 31. The first clamping groove 30 is opened at the top of the support 20, and the second clamping groove 31 is opened at the bottom of the first clamping groove 30.

[0020] The working principle of this utility model: The specific internal structure of the debugging instrument body 10 is not shown in the figure. The debugging instrument body 10 includes a microcontroller module, a switching power supply module, a D / A conversion module, an LCD display module, a keyboard module, and a measurement module. The microcontroller module receives signals from the keyboard module and the measurement module, converts the analog signals from the measurement module into digital signals, and sends them to the LCD display module for display. It also uses its built-in SPI asynchronous serial module to send digital signals to the D / A module, converting them into the required analog current output. The switching power supply module provides power to other modules of the debugging instrument. The D / A conversion module receives high-voltage power from the high-voltage output switching power supply module and serial digital command values ​​from the microcontroller U6, outputting a certain amount of current (0-24mA for elastic elements) and voltage signals (0-5VDC) for instrument calibration. The LCD display module displays the content sent by the microcontroller module. The keyboard module sets the display mode and the required current value or the percentage opening value of the intelligent instrument. The measurement module measures the control signals sent from the control room to the intelligent instrument to be calibrated during the instrument calibration process. The debugger body 10 is placed in the first clamping slot 30 or the second clamping slot 31, which can be adjusted according to the shape of the outer shell of the debugger body 10. The adjusting screw 33 is rotated and is rotatably connected to the base plate 21. The adjusting screw 33 is a bidirectional screw. By adjusting the screw 33, the sliders 32 at the bottom of the two support seats 20 are moved to slide in the corresponding grooves, so that the two support seats 20 can move closer to each other to clamp and limit the debugger body 10. The support seats 20 can be fitted with rubber sleeves to ensure the clamping effect of the debugger body 10 and to avoid damage to the debugger body 10. It is convenient to disassemble and assemble the debugger body 10 and store it. The elastic element 24 supports the base plate 21 so that the base plate 21 can float in the support seat 20. The debugger body 10 is connected to the handheld digital meter through the connecting cable. The floating base plate 21 can reduce the damage to the debugger body 10 and the instrument connection port caused by the pulling of the wire.
