In the present embodiment, the terms of orientation such as "bottom", "top", "peripheral edge", "center", and the like are explained based on the drawings.

Specifically, the pressing type shaver comprises a shell 14, a first cavity 18 arranged in the shell and used for mounting a shaving driving assembly, and is characterized in that the shaving driving assembly comprises a roller-type cutter 8 arranged in the first cavity, a second cavity 19 arranged in the roller-type cutter and penetrating through the center of the bottom of the roller-type cutter, a third cavity 20 arranged in the roller-type cutter 8 and penetrating through the center of the top of the roller-type cutter 8 and communicated with the second cavity, an upper half shaft 1, a first gasket 3 and a second gasket 4, a reset spring 2, a second gasket and a third spring, wherein the upper half shaft 1 is arranged in the second cavity, the first gasket 3 and the second gasket 4 are sleeved on the upper half shaft 1 and arranged in the third cavity, the reset spring is arranged between the first gasket 3 and the upper half shaft 1 and used for resetting the upper half shaft 1 after being pressed, the upper end sleeve is arranged on the lower end edge of the upper half shaft 1, the lower end of the upper half shaft penetrates through the bottom center of the shell and is in interference fit with the bottom center of the roller type cutter 8, the positioning groove 9 is annularly formed in the second cavity 19, the gear assembly 15 is arranged in the second cavity 19, is slidably sleeved in the positioning groove and enables the rotating worm 7 to rotate under the driving action of pressing the upper half shaft, the second groove 16 is formed in the shell and used for providing a beard entering channel, the blade 17 is obliquely arranged on the roller type cutter 8 and used for being matched with the second groove 16 to cut beards, and the pair of symmetrical rotating force couples 10 are arranged at the bottom of the second cavity 19 and have side walls attached to the inner wall of the roller type cutter. Wherein, the top of the rotating worm 7 is provided with a blind hole 21 matched with the lower end of the upper half shaft 1. In addition, a first groove 5 matched with the gear assembly 15 is formed on the upper half shaft 1. The side wall edge of the upper half shaft 1 is provided with a rack 6; the gear assembly 15 comprises a gear carrier respectively matched with the first groove 5 and the positioning groove 9, a ratchet wheel 11 fixed on the gear carrier and meshed with the rack 6, a first gear 12 fixed on the gear carrier and meshed with the ratchet wheel 11, and a second gear 13 fixed on the gear carrier and meshed with the first gear 12 and the rotating worm 7 respectively.
