AI Technical Summary
Technical Problem
During use, the needle cannot be cleaned in time and needs to be removed during cleaning, which can easily lead to damage to the needle and reduce service life.
Method used
A high-life double-head test probe is designed, adopting a spiral sliding structure and an elastic engaging limit structure, which protects and cleans the needle through a slidable cylinder and cleaning cotton, and heats up impurities that are difficult to clean through a heating tube.
Benefits of technology
It effectively avoids the needle being affected by the external environment during use, clean the needle in time, avoids impurities staying, and extends the service life of the probe.

Abstract
The utility model discloses a long-life double-end test probe, which comprises a needle tube, cylinders are respectively screwed at two ends of the needle tube, the inner walls of the cylinders and the outer wall of the needle tube are provided with matched threads, the outer ends of the cylinders are respectively provided with openings, and needle heads are inserted into the openings. According to the long-service-life double-head test probe, the cylinder and the probe head form a spiral sliding structure through the needle tube, and the cylinder and the needle tube form a spiral locking structure, so that the rear end of the probe head is protected through the slidable cylinder in the working process of the probe head, and the whole probe head is prevented from being influenced by the external environment in the detection process; a sliding block of the device is inserted into a limiting hole through a fixing plate and a second elastic limiting block to form an elastic clamping limiting structure with a protective cover, and a fixing frame and the protective cover form a sliding structure through the sliding block in a sliding groove, so that a needle head is cleaned in time through slidable cleaning cotton; therefore, impurities are prevented from staying on the needle for a long time and being inconvenient to clean.
