Embodiment Construction

[0016] As shown in Figure 2(a) and Figure 2(b), a double-sided security razor holder includes a handle 1, a blade chassis 2 and an upper pressure plate 3, and the blade 4 is mounted on the blade chassis 2 and the upper pressure plate 3 between.

[0017] Both sides of the upper pressing plate 3 respectively extend a protective edge 31 along the length direction, and the protective edge 31 is located in the middle of the two sides of the upper pressing plate 3, and the length of the upper pressing plate 3 after extending the protective edge 31 on both sides is greater than or equal to the blade 4 length;

[0018] The four corners of the upper platen 3 respectively extend a protrusion 32 along the width direction, and the outline of each protrusion 32 is arc-shaped. The square boss 321 at the corner of the mouth, and the maximum width W of the upper pressing plate 3 after extending the protrusions 32 on both sides of the width is greater than or equal to the width of the blade 4...
