Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] This utility model proposes a portable electrical fault diagnosis device, including: a handheld ammeter 1; the handheld ammeter 1 is equipped with a display screen 101, and the display screen 101 is also equipped with a knob 2 for detecting gear adjustment. The outer wall of the knob 2 has twelve anti-slip grooves 201 arranged in a circular array. The top surface of the handheld ammeter 1 is marked with twelve gear indicators 202 arranged in a circular array. The twelve gear indicators 202 are aligned with the twelve anti-slip grooves 201. A spring rod 203 is fixed to the top surface of the handheld ammeter 1. The protruding end of the spring rod 203 is engaged in the anti-slip groove 201. When adjusting the gear, the knob 2 can be turned. At this time, the anti-slip groove 201 can prevent the hand from slipping. The gear adjustment head can achieve gear locking through the engagement of the protruding end of the spring rod 203 with the anti-slip groove 201, preventing accidental touch of the knob 2 from causing gear adjustment.

[0029] The handheld ammeter 1 has two test pens 4 inserted into its top. The top of the handheld ammeter 1 has two ring-shaped bases 401 fixed. When the test pens 4 are inserted into the top of the handheld ammeter 1, the outer wall of the test pen 4 plug is in close contact with the inner wall of the base 401. During use, the close contact between the outer wall of the test pen 4 plug and the inner wall of the base 401 can improve the waterproof effect at the plug and prevent the plug from becoming loose.

[0030] The handheld ammeter 1 has a charging port 102 on its bottom surface. A rectangular block 5 is fixed on the bottom surface of the handheld ammeter 1. Two stepped shaft-shaped guide rods 501 slide on the base block 5. The rear end of each guide rod 501 is fixed on a baffle 502. The baffle 502 covers the charging port 102. When not charging, the baffle 502 can prevent dust from entering the charging port 102.

[0031] The handheld ammeter 1 has two slots 103 on its bottom surface, both of which are hemispherical groove structures. A protrusion 503 is fused to the top surface of the baffle 502. The protrusion 503 is also hemispherical. When the baffle 502 is closed, the protrusion 503 engages with the slot 103 on the rear side of the bottom surface of the handheld ammeter 1. When the baffle 502 is fully open, the protrusion 503 engages with the slot 103 on the front side of the bottom surface of the handheld ammeter 1. During use, the baffle 502 can be positioned by engaging the protrusion 503 with the slot 103, thus ensuring the dustproof effect of the baffle 502.

[0032] Among them, two protective blocks 3 are attached to the outside of the handheld ammeter 1, and both protective blocks 3 are made of rubber.

[0033] Example 2, based on Example 1, such as Figures 1 to 6 As shown, the two protective blocks 3 are protective components of the handheld ammeter 1. Both protective blocks 3 are sleeved on the outside of the handheld ammeter 1. Both protective blocks 3 are made of rubber. During use, the protective blocks 3 protect the handheld ammeter 1, which can reduce the chance of damage after the handheld ammeter 1 is dropped.

[0034] The working principle of this embodiment is as follows: During fault diagnosis, turn knob 2 to adjust to the detection gear and place the two detection pens 4 in contact with the detection area for detection; when adjusting the gear, simply turn knob 2. The gear adjustment head can achieve gear locking by engaging the spring rod 203 extension end with the anti-slip groove 201; when charging, pull the baffle 502 forward so that the protrusion 503 engages with the front slot 103, at which point the charging socket 102 is exposed. Insert the charging head into the charging socket 102 for charging; after charging is complete, pull out the charging head and push the baffle 502 backward until the protrusion 503 engages with the rear slot 103.
