[0019] The present application will now be described in more detail with reference to the accompanying drawings and embodiments.

[0020] This application discloses a handheld vehicle inspection tool, as shown in Figures 1 to 5. It includes a front shell 1, a rear shell 2, and a detection line 3. The front shell 1 and the rear shell 2 are joined together to form a housing. A main board 5 is provided inside the housing. A recessed wire-holding groove 6 is formed at the junction of the front shell 1 and the rear shell 2, extending circumferentially along the housing. The first end of the detection line 3 is fixedly connected to the housing and electrically connected to the main board 5. The wire of the detection line 3 surrounds the housing and is held within the wire-holding groove 6. A connector 7 is provided at the second end of the detection line 3. A receiving compartment 4 is provided at the top of the housing, and the connector 7 is inserted into the receiving compartment 4. The length of the detection line 3 is greater than the extension length of the wire-holding groove 6. The portion of the detection line 3 outside the wire-holding groove 6 forms an inverted "U"-shaped hanging portion 30.

[0021] In the above structure, the front shell 1 and the rear shell 2 are joined and fixedly connected to form a shell. The main board 5 is fixed inside the shell. A wire-holding groove 6 is formed at the junction of the front shell 1 and the rear shell 2. The wire-holding groove 6 is concave and is used to accommodate and hold the wire of the detection line 3. One end of the detection line 3 is directly fixed to the shell, and the other end of the detection line 3 is provided with a connector 7 for signal transmission. The part of the detection line 3 outside the wire-holding groove 6 is bent into an inverted "U" shape to form a hanging part 30. The connector 7 is located at the end of the hanging part 30. When the connector 7 is inserted into the receiving compartment 4, the tool can be hung on the wall or other locations using the hanging part 30, making it convenient for the user to access.
