In view of the above-mentioned problems and deficiencies of the prior art, one of the purposes of this creation is to provide a pipe cutter structure that can be used with driving power through structural innovation.

In order to achieve the above-mentioned purpose, the author proposes a pipe cutter structure, which includes a housing, a driving tooth group, and a cutter head group. The shell has a cavity and a shaft hole communicating with the outside. The driving gear set is pivoted in the housing and includes mutually fit A main gear, a plurality of auxiliary gears and a screw accommodating in the shaft hole. The cutter head set is housed in the housing and fits with each auxiliary gear. It includes a cutter head, a cutter shaft arranged on the cutter head, a pre-compression element pivoted on the cutter shaft, and a first and second cutter arms. . With the composition of the above components, the screw is connected with the drive tool to transmit power, so that the drive gear set drives the cutter head set to spin, so that the first and second knife arms receive the pre-pressure applied by the pre-pressure element, and place them in opposite directions. The pipe in the hole is cut.
