[0031] Furthermore, there are four carrier spring top posts 86, with two carrier spring top posts 86 forming a group, and the two carrier spring top posts 86 are symmetrically distributed with the center line of the front side of the PCB carrier board 87 as the axis of symmetry.
[0032] Example 2:
[0033] Based on Example 1, please refer to Figure 5-6Furthermore, in conjunction with Embodiment 1, the heat dissipation and filtration mechanism 9 includes a first connecting platform 91, which is fixedly connected to the outside of the base 1. A second connecting platform 92 is fixedly connected to the outside of the base 1. A motor 93 is fixedly connected to the top of the first connecting platform 91. The output end of the motor 93 extends through the first connecting platform 91 and is fixedly connected to a threaded rod 98 inside. A limit rod 99 is fixedly connected inside the second connecting platform 92. A movable frame 94 is slidably connected to the outside of the limit rod 99. A bellows baffle 95 is fixedly connected to the outside of the movable frame 94. A connecting frame 97 is provided inside the movable frame 94.

[0034] Furthermore, the ash-adhesive roller 96 contacts the heat sink plate 6, and a locking bolt is provided between the movable frame 94 and the connecting frame 97 to facilitate more stable use.
[0035] Furthermore, the movable frame 94 is threadedly connected to the threaded rod 98, the movable frame 94 is slidably connected to the first connecting platform 91, and the movable frame 94 is slidably connected to the second connecting platform 92, which facilitates a more stable cleaning process.

[0037] In actual operation, when this device is used, the threaded rod is first used in a T-shaped threaded rod to make it self-locking. The operator electrically connects the channel test board 7, test probe 89, operation display screen 4 and power switch 5 and other related mechanisms. Then, the operator places the angle grinder chainsaw controller on top of the PCB carrier board 87. The cylinder body 84 works to make the upper needle plate frame 85 slide outside the upper needle plate guide post 88, thereby moving the test probe 89 until it contacts the angle grinder chainsaw controller. At the same time, the device is equipped with stroke position detection, and the built-in tooling test board monitors the stroke position status in real time. When the cylinder is pressed down to the end, all the test probes corresponding to the 5 channel test boards 7 are in position. The stroke position equipment provides feedback to the tooling test base plate. Normal functional testing can be performed in this state. Through the hardware with speed adjustment and high-bar function, the angle grinder chainsaws of the 5 channels are tested. The controller has a discharge function and applies various signals to the five channel test boards 7 through the tooling test board to achieve the normal working state of the angle grinder / chainsaw and determine whether its state is abnormal. The test results of the controllers placed in the five channels are displayed on the operation display screen 4. The indicator lights 83 light up green when the test is successful and red when it fails, accompanied by an alarm sound, to remind the user. At the same time, this device has a power supply voltage detection function, which can automatically identify different types of controllers and apply the corresponding voltage value. The heat sink 6 is set to meet the airflow inside the base 1, thereby meeting the heat dissipation of the channel test boards 7. The heat sink 6 filters dust in the air. The motor 93 works to make the threaded rod 98 rotate, which, together with the limit rod 99, makes the movable frame 94 move, and together with the connecting frame 97, makes the dust-adhesive roller 96 move, thereby removing dust and other impurities adhering to the surface of the heat sink 6.
