Multipurpose periodontal probe

A multipurpose periodontal probe comprises a first fixing rod, a second fixing rod is movably connected to the interior of the first fixing rod, a connecting rod is movably connected to the interior of the second fixing rod, a probe head is movably connected to the end, away from the second fixing rod, of the connecting rod, and a first vertical rod is movably connected to the top of the outer surface of the first fixing rod. A second vertical rod is movably connected to the top of the outer surface of the second fixing rod, fixing grooves are formed in the tops of the outer surfaces of the second fixing rod and the connecting rod, the first vertical rod and the second vertical rod are matched with the fixing grooves, and the bottom end of the first vertical rod sequentially penetrates through the first fixing rod and the second fixing rod and extends into the fixing grooves. Compared with the prior art, the periodontal probe can be rapidly and conveniently contracted, so that the size of the periodontal prob
