[0016] In this embodiment, the assembly of various components, combined with the orientation marking function of the indicator, allows for a direct display of the clamping force based on the orientation of the indicator, thus meeting the daily testing needs of circuit equipment.

[0017] If necessary, the clamping force of the female needle can be detected and quantified through the technical solution of the embodiments of this application. If the clamping force of the female needle is less than the standard value, the female needle will be replaced to avoid the occurrence of a loose connection between the male and female needles.

[0018] It should be noted that, as Figure 1 and Figure 2As shown in the two figures, the connection methods of the male needle (6) and the needle handle (5) are different. In fact, in the technical solution of this application, the structure of the male needle (6) and the needle handle (5) and the connection structure between them are not limited. As long as they can meet the actual working requirements, they can be plug-in or threaded. Therefore, this application mainly improves other technical aspects, and the specific implementation can be adapted according to the actual situation.

[0020] It should be noted that the technical details of the embodiments of this application are as follows: The male needle 6 is installed on the needle handle 5. The needle handle 5 and the guide post 4 are threaded together. The guide post 4 is connected to one end of the spring 3. The other end of the spring 3 is connected to the base 2 to form a whole. The whole is placed inside the steel cylinder 1. The steel cylinder 1 and the base 2 are connected by the set screw 12. The indicator 11 is installed on the guide post 4. When the male needle 6 is inserted into the female needle and pulled outward, the male needle 6, needle handle 5, guide post 4, and indicator 11 will be pulled by the clamping force. The spring 3 extends, and the indicator 11 extends accordingly, corresponding to the scale on the steel cylinder 1, to show the clamping force. The needle shank 5 and the guide post 4 are threaded together, allowing for the replacement of male needles 6 of different sizes when using different female needles; The above structure can maximize the clamping force of the female needle. The guide post 4, spring 3, base 2, and indicator 11 are connected as a whole. When the male needle 6 and the female needle are separated, the guide post 4 and indicator 11 will stretch the spring 3. The markings on the indicator 11 correspond to the scale on the steel cylinder 1, indicating the clamping force.
