The invention relates to a
multimeter with stable plugging and convenient use. The
multimeter comprises a main body, two meter pens, three plugging ports and three plugging connectors, and further comprises a switching mechanism and three reinforcing mechanisms, wherein the switching mechanism comprises a connecting block, a driving
assembly, a sliding rod, a moving block, a cable, an elastic piece, a sliding groove, two sliding blocks, two first springs and two
metal contacts; each reinforcing mechanism comprises a limiting rod, an air conveying
pipe, an air storage box, a thin film, a push rod, an annular air bag and two supporting assemblies; each supporting
assembly comprises a guide rail, a second spring and a sliding sleeve; and each driving
assembly comprises a screw rod and a turntable. According to the
multimeter with stable plugging and convenient use, direct switching of one meter pen between a
voltage measurement interface and a current measurement interface is realized bymeans of the switching mechanism, so that an operator does not need to frequently plug and unplug the plugging connectors, the use convenience of the multimeter is improved, the plugging connectors can be reinforced by means of the reinforcing mechanisms, and the connection firmness of the plugging connectors and the plugging ports is improved.
