TECHNICAL FIELD

[0001] The utility model relates to the field of wire testing, in particular to a wire testing instrument with high stability. BACKGROUND

[0002] The wire testing instrument is a device for checking whether the internal wires of the wire are normally conductive. For example, in the production of electronic equipment, the continuity of the wires connecting the circuit board and various components can be determined through continuity testing. By applying a small test current to both ends of the wire, it is detected whether there is a corresponding voltage signal returned, so as to determine whether the circuit is connected. If the circuit is conductive, the current can pass smoothly, and the instrument will give a normal prompt; if there is a break in the circuit, the current cannot pass, and the instrument will determine that it is abnormal.

[0003] The utility model discloses a precision low pressure wire testing instrument of connecting stability, including detection appearance body, first detection interface and second detection interface are provided on the top end surface of detection appearance body, and the detection appearance body between first detection interface and second detection interface is equipped with the sliding slot, two groups of fixed frame that are symmetrically arranged are installed in the sliding slot, the fixed frame includes sliding block, the sliding block is limited in the sliding slot, and the top end of sliding block is vertically provided with support rod, in today's wire testing field, the wire testing instrument is the key equipment for ensuring the quality and performance of the wire. However, the existing most wire testing instruments have significant limitations in clamping the wire. At present, the clamping mechanism of fixed clamping block is generally adopted, that is, the clamping block with specific shape and size is used to clamp the wire to be tested on the outer surface of the device. The design of the fixed clamping block is customized based on the specific specifications and models of the wire, and the shape, size and clamping force of the clamping block are fixed. This means that when facing different specifications and models of wires, such as wires with large differences in diameter, the clamping device is difficult to adapt effectively, and since it cannot be flexibly adjusted to meet the clamping needs of wires of various specifications, its use range is greatly limited to a single one matching the design of the clamping block, which seriously affects the universality and efficiency of the wire testing instrument in diversified wire testing scenarios.
