Different data wires are passed through threading holes of different threading disks according to different connection positions and finally connected to the test instrument. Since each data wire is led out through a different threading hole, the led-out data wires will not be entangled, and the data wires can be connected in a more scientifically planned connection manner.

[0017] 3. In the present invention, an angle adjustment component and an instrument installation mechanism are provided in a matching manner. When installing the instrument, the instrument is directly placed on the instrument installation platform. At this time, the pressure block is pressed and moved downward, and the side installation plate on its outer side moves downward synchronously. The limit pin can also move downward synchronously and disengage from the clamping hole set on the bottom surface of the movable slider.

[0031] The specific implementation method is as follows: when testing, open the wire box 71, lead out each data line, pass different data lines through the threading holes 65 of different threading trays 66 according to different connection positions, and finally connect to the test instrument. Since each data line is led out through a different threading hole 65, the led-out data lines will not be entangled, so that the data lines can be connected in a more scientifically planned connection method.

After the problem is detected, the cause can be quickly found, and the guide of the wiring harness can be quickly adjusted and positioned according to the use requirements, further improving the actual application effect of the device.

[0034] The specific implementation method is as follows: when the moving mechanism 7 moves to one side, the flip plate 742 can be flipped under the action of the side push spring 741. When the lateral displacement of the moving mechanism 7 reaches the maximum, the flip plate 742 will also directly flip to a horizontal position, and the side wall of the flip plate 742 will contact the placement surface, thereby realizing an increase in the overall bottom area of ​​the structure and improving the stability of the overall equipment.

[0036] The instrument mounting mechanism 5 includes an instrument mounting platform 51, and the instrument mounting platform 51 includes an adjusting motor 53. The adjusting motor 53 is fixedly mounted on an outer wall of one side of the mounting top frame 41. A mounting base plate 54 is fixedly mounted on one end of the output shaft of the adjusting motor 53. The mounting base plate 54 is slidably connected with a top groove provided on the top of the mounting top frame 41. The instrument mounting platform 51 is fixedly mounted on the top of the mounting base plate 54. A slide groove 52 and a center groove 56 are provided on the top surface of the instrument mounting platform 51. A positioning component 55 is provided inside the slide groove 52. The positioning component 55 includes a transverse slide rod 554 and a spring sleeve shaft 558. The transverse slide rod 554 is fixedly mounted inside the center groove 56 laterally, and the spring sleeve shaft 558 is fixedly mounted in the center groove longitudinally. 56, a pressure block 557 is slidably installed on the outside of the spring sleeve shaft 558, one end of the pressure block 557 passes through and extends to the outside of the central groove 56, the transverse slide bar 554 is transversely fixedly installed in the inside of the slide groove 52, and a movable slider 552 is slidably installed on the outside of the transverse slide bar 554, and a sleeve spring 553 is sleeved on the outside of the transverse slide bar 554, and a positioning plate 551 is fixedly installed on the top of the movable slider 552, and a clamping block is fixedly installed on the outer wall of one side of the positioning plate 551, and side mounting plates 556 are transversely fixedly installed on the outer walls of both sides of the pressure block 557, and a limiting pin 555 is fixedly installed on the top surface of the side mounting plate 556, and one end of the limiting pin 555 is embedded in the clamping hole set on the bottom surface of the movable slider 552.

[0037] The specific implementation method is as follows: when installing the instrument, the instrument is directly placed on the instrument mounting platform 51. At this time, the pressure block 557 is pressed and moved downward, and the side mounting plate 556 on its outer side moves downward synchronously, and the limit pin 555 can also move downward synchronously to disengage from the clamping hole set on the bottom surface of the movable slider 552. At this time, the sleeve spring 553 loses its restriction, and the positioning plate 551 can be pulled sideways, and the two positioning plates 551 are close to each other. The clamping blocks set on the side walls of the two positioning plates 551 can be clamped into the instrument clamping holes to complete the firm positioning of both sides of the instrument. During testing, the adjustment motor 53 can be turned on as needed to adjust the angle of the mounting base plate 54, thereby completing the adjustment of the angle of the instrument. Due to the clamping effect of the clamping block, the instrument as a whole will not rotate, which is convenient for the working effect of the instrument in various workstation states.

[0038] Through this design, the instrument can be quickly positioned and installed during testing without complicated assembly steps, and the overall structure does not have an electric positioner, which helps to reduce equipment costs and can complete work inspections at various workstations, improving the actual application effect of the equipment.

[0039] Working principle: When installing the instrument, directly place the instrument on the instrument mounting platform 51. At this time, the pressure block 557 moves downward under pressure, and the side mounting plate 556 on its outer side moves downward synchronously. The limit pin 555 can also move downward synchronously and disengage from the card hole set on the bottom surface of the movable slider 552.

During the inspection, the adjustment can be opened according to the needs. The motor 53 adjusts the angle of the mounting base plate 54, thereby completing the adjustment of the angle of the instrument. Due to the card-embedded effect of the card block, the instrument as a whole will not rotate, which is convenient for the working effect of the instrument in various workstation states. When testing, open the wire box 71, lead out various data lines, and pass different data lines through the threading holes 65 of different threading disks 66 according to different connection positions, and finally connect with the test instrument. Since each data line is led out through a different threading hole 65, the led-out data lines will not be entangled, which can make the data lines more The connection is made in a scientifically planned connection mode. When a fault occurs in the subsequent test, the cause can be quickly checked. At the same time, when the connection position of the data line needs to be changed, one end of the base 1 is lifted to make the mobile mechanism 7 disengage from the placement surface, and the threading disk 66 is rotated to achieve the guide change of the wire. When the threading disk 66 rotates, the meshing teeth 68 on its outer side can drive the driven gear 69 to rotate, and the transmission stud 610 can rotate. The transmission stud 610 can drive the mobile mechanism 7 to move to one side. After the adjustment is completed, the rotation can be stopped directly, and the base 1 can be put down. At this time, the mobile mechanism The movable mechanism 7 contacts the placement surface again. At this time, there is a large friction between the movable mechanism 7 and the contact surface. Therefore, the adjusted threading disk 66 can be automatically positioned without manual control, thereby ensuring the guiding and adjusting effect of the data line. When the movable mechanism 7 moves to one side, the flip plate 742 can be flipped under the action of the side thrust spring 741. When the lateral displacement of the movable mechanism 7 reaches the maximum, the flip plate 742 will also directly flip to a horizontal position, and the side wall of the flip plate 742 will contact the placement surface, thereby realizing an increase in the overall bottom area of ​​the structure and improving the stability of the overall equipment.
