Description

Clamp tool for portable transformer detection Technical Field The utility model relates to the technical field of transformer detection, in particular to a fixture tool for portable transformer detection. Background When detecting the inductance of the miniature transformer, an inductance tester is usually used, and in the actual detection process, the inductance tester is connected with two wires, one ends of the two wires, far away from the inductance tester, are respectively pressed against two pins of the miniature transformer, so that the inductance of the miniature transformer is detected. In contrast, the Chinese application patent number CN202320685725.3 discloses a pin clamp for transformer detection, which comprises a connecting sleeve, a enclasping sleeve and a locking sleeve, wherein the enclasping sleeve is arranged at one end of the connecting sleeve and consists of a plurality of enclasping petals, the outer side surfaces of the enclasping petals form a round table-shaped structure, the inner side surfaces of the enclasping petals form an inverted round table-shaped structure, one end of the connecting sleeve, which is far away from the enclasping sleeve, is coaxially and fixedly sleeved outside a lead, and the locking sleeve is used for tightening the enclasping petals outside the lead. The clamp can ensure that a wire is always in contact with a pin of a transformer in the detection process, can avoid poor contact between the wire and the pin caused by manual holding of the wire, is directly fixed with the pin through the clamp, is fixed through the pin, does not need to be held by both hands, can release both hands for data recording, can be suitable for pins with different sizes, and can also be used for adjusting the clamping force through the engagement quantity of the first clamping tooth group and the second clamping tooth group. This anchor clamps can contact wire and pin through setting up the cooperation of connecting sleeve, holding tightly cover and lock sleeve, but the contact end of wire and pin is located the inboard of connecting sleeve, holding tightly cover and lock sleeve, can't direct observation inside contact condition from the outside, staggers easily between wire and the pin, and leads to the contact failure, influences detection experience. Therefore, in order to solve the above-mentioned problem, a fixture tool for detecting a portable transformer is provided. Disclosure of utility model The utility model aims to provide a fixture tool for detecting a portable transformer, which solves the problems that in the prior art, the fixture in the prior art is provided with a connecting sleeve, a clasping sleeve and a locking sleeve to be matched, so that a lead and a pin can be contacted, but the contact ends of the lead and the pin are positioned at the inner sides of the connecting sleeve, the clasping sleeve and the locking sleeve, the contact conditions of the inside cannot be directly observed from the outer sides, the lead and the pin are easy to be staggered, the contact is poor, and the detection experience is affected. In order to achieve the purpose, the utility model provides the technical scheme that the fixture tool for detecting the portable transformer comprises a cylinder body; the bottom surface of the cylinder body is provided with a guide groove, and the side wall of the upper end of the cylinder body is provided with an empty groove; the upper end of the cylinder body is provided with a positioning structure, the positioning structure comprises a fixed plate, the fixed plate is fixedly arranged on the outer wall of the upper end of the cylinder body, the inner side of the fixed plate is fixedly connected with a guide rod, the surface of the guide rod is sleeved with a spring, and the outer side of the guide rod is slidably provided with a clamping ring; the cylinder body is provided with two groups; The lower extreme of barrel is installed movable structure, movable structure includes fixed block and fixed cylinder, fixed block and fixed cylinder are installed respectively on the lower extreme outer wall of two sets of barrels, the tip fixedly connected with rotation axis of fixed block, the outside fixedly connected with coil spring of rotation axis.
