It achieves automatic gear shifting through the coordinated work of components such as the torque converter, planetary gear mechanism and control system, making driving more convenient and comfortable. The normal operation of an automatic transmission depends on precise electronic control. Circuit abnormalities may cause problems such as uneven gear shifting, setbacks, inability to shift gears, and even inability to drive the vehicle, affecting the performance and safety of the vehicle. Through circuit testing, potential problems can be discovered in the early stages of a fault, and repairs can be carried out in a timely manner to avoid the expansion of the fault, reduce repair costs and vehicle downtime.

Two fixing frames 211 are installed, and the front surfaces of the four fixing frames 211 are fixedly installed with threaded tubes 212, and the interiors of the four fixing frames 211 are movably embedded with extrusion rods 213, one end of the four extrusion rods 213 is fixedly connected with a suction cup 214, and the other end of the four extrusion rods 213 is fixedly installed with a rotating block 215, and the outer surfaces of the four extrusion rods 213 are fixedly sleeved with threaded sleeves 216, and the outer surfaces of the four threaded sleeves 216 are respectively threadedly embedded in the interiors of the four threaded tubes 212, and the outer surfaces of both sides of the first case 101 Two fixing plates 207 are respectively installed by bolts, and two limiting rings 208 are fixedly installed on the outer surface of one side of the four fixing plates 207. The inner walls of the eight limiting rings 208 are fixedly connected with anti-slip rings 209. The eight anti-slip rings 209 are grouped into two vertical anti-slip rings 209. The outer surfaces of the four fixing rods 202 are in contact with the inner walls of the four groups of anti-slip rings 209 respectively. The outer surfaces of the two first binding belts 203 and the outer surfaces of the two second binding belts 204 are fixedly connected with two elastic belts 210 near the winding rod 201.

[0034] In this embodiment, when in use, the first binding strap 203 and the second binding strap 204 both have a certain elasticity. The rear surface of the first watch case 101 is placed on the arm, and then the first binding strap 203 is pulled to cover the arm, and then the second binding strap 204 is pulled.

The fixing component 2 provides two different fixing methods, which is more flexible. The tester can choose according to needs, which solves the problem that when performing rapid diagnosis of the automatic transmission circuit, the tester needs to use both hands to take the two test leads respectively. When the multimeter is placed on the desktop, it is easy to move due to collision or accidental pushing, resulting in inaccurate measurement; when holding the multimeter, it is inconvenient to operate and it is also inconvenient to check the readings. The winding rod 201 is set in a U shape, such as Figure 7 As shown, the connecting wire of the test lead is wound around the winding rod 201, and then the test lead is inserted into the elastic band 210, so that the test lead and the connecting wire can be stored, thereby increasing the storage function of the multimeter.

The rear surface of the connecting plate 301 is provided with a movable groove 303, and an adjustment plate 304 is movably embedded in the movable groove 303. A rotating rod 305 is movably embedded in the adjusting plate 304, and both ends of the rotating rod 305 are respectively fixedly installed in the movable groove 303. On both sides of the interior, a plurality of latch teeth 308 are fixedly installed on the front surface of the adjustment plate 304, a damping shaft 306 is arranged inside the movable groove 303, and a support plate 307 is arranged on the outer surface of the damping shaft 306.

[0038] In this embodiment, when the multimeter needs to be placed vertically on the workbench, the adjustment plate 304 is pressed forcefully to separate the magnetic block 310 from the magnet 312, and then the adjustment plate 304 is toggled to rotate outward with the rotating rod 305 as the axis, and then the support plate 307 is toggled to rotate, and one end of the support plate 307 is clamped on the clamping tooth 308 to limit the adjustment plate 304. The multimeter is supported by the adjustment plate 304 to facilitate its vertical placement on the table. There is no need to support the multimeter with the help of other objects, which improves convenience. By adjusting the rotation angle of the support plate 307, the position of the support plate 307 clamped on the clamping tooth 308 is adjusted, and then the angle of the adjustment plate 304 is adjusted to achieve angle adjustment when the multimeter is placed vertically, which is convenient for different testers to choose a suitable viewing angle and enriches the functionality of the multimeter.

[0039] The effect and working principle achieved by the entire mechanism are as follows: place the rear surface of the first watch case 101 on the arm, then pull the first binding strap 203 to cover the arm, and then pull the second binding strap 204.
