The utility model discloses a multimeter with a wire take-up function. The multimeter comprises a multimeter body; grooves are formed in the left side surface and right side surface of the multimeterbody; multimeter probes are clamped in the grooves through meter probe clamps; a PCB is disposed in the multimeter body; a wire take-up cavity located below the PCB is formed at the bottom of the multimeter body; a pair of wire take-up rollers are disposed in the wire take-up cavity through rotating shafts; and an installation plate is arranged between the wire take-up rollers. With the multimeteradopted, a wire can be drawn and stretched according to the needs of a user; the wire wound on the wire take-up rollers can be pulled out through a through hole; when the wire extends out of the multimeter body, after the required length of the wire is confirmed, and a plugging block is plugged so as to fix the length of the wire; when the wire is collected, the user can hold a second rubber bodyso as to pull out the second rubber body, and the wire can be released, and at the same time, a wire take-up handle is rotated, so that the wire can be wound on the wire take-up rollers slowly, and therefore, the wire can be prevented from being damaged, and the service time of the wire can be prolonged. The multimeter has the advantages of simple structure and high practicability.
Description
technical field [0001] The invention relates to the technical field of code scanning for items, in particular to a multimeter with a wire-receiving function. Background technique [0002] The main purpose of the multimeter is to measure voltage, current and resistance. It is a highly practical measuring device. Most of the multimeters in the prior art are designed with a separate body and pen. When using it, insert the wire on the pen into the The jack on the meter body is sufficient. However, due to the complexity of the conditions of use or the use of the environment, the staff cannot carefully wrap the thread on the watch needle, and can only simply fold it. Life expectancy is greatly shortened. Contents of the invention [0003] Aiming at the problems in the related art, the present invention proposes a multimeter with a wire-receiving function to overcome the above-mentioned technical problems existing in the related art. [0004] Technical scheme of the present in...
