Technical Field

The present invention relates to a multiple-blade razor, and more particularly to an adjustable multiple-blade razor with adjustable blade spacing.

Background

At present, the known multi-edged shavers are used to shave beards because of the accumulation of hair residue between the blades, so that conventional multi-edged shavers are only suitable for shaving thin and short beards, but are very laborious for long or thick thin beards.

Disclosure of Invention

In order to overcome the disadvantage that the conventional multi-edged razor is only suitable for short and shallow beard, the present invention provides an adjustable multi-edged razor which can adjust the pitch of blades, thereby facilitating both shaving of long beard and removal of residue accumulated between the blades by increasing the distance between the blades.

The technical scheme adopted by the invention for solving the technical problems is as follows: the invention comprises an upper tool bit, a lower tool bit, a connecting cylinder, a knob, a limiting pin, a handle, an upper blade, a lower blade, a guide pin, a lock seat, a telescopic shaft, a screw head, a guide groove, a limiting groove and a lock hole.

The handle is of a cylinder structure, a screw hole is formed in the central axis of the handle, a limiting groove is formed in the outer cylinder wall at the upper end of the handle, and the limiting groove is a groove surrounding the outer cylinder wall of the handle. The knob is of an annular cylinder structure, is sleeved on the upper end head of the handle and is matched and positioned with the limiting groove through the limiting pin. The connecting cylinder is arranged above the knob and is connected with the knob through a lower end head, and an inner hole of the connecting cylinder is communicated with a screw hole on the handle. The lower end shaft head of the telescopic shaft is set to be a screw head, a longitudinal guide groove is formed in the middle of the telescopic shaft, and the guide groove is an oblong through hole which vertically penetrates through the telescopic shaft. The telescopic shaft is arranged in the connecting cylinder and is in threaded connection with a screw hole on the handle through a screw head at the lower end, and the guide pin is arranged in the guide groove and is respectively connected with through holes arranged on the left and right side cylinder walls of the connecting cylinder through a left end and a right end. The upper tool bit and the lower tool bit are both in rectangular plate structures, the upper tool bit is connected with the upper end head of the telescopic shaft through a connecting rod, the lower tool bit is connected with the upper end head of the connecting cylinder through a connecting rod, and the upper tool bit and the lower tool bit are arranged in parallel and are perpendicular to the handle. The lock seat is composed of a rectangular bottom plate and a plurality of buckles vertically connected to the bottom plate, and the buckles are of T-shaped cylindrical structures formed by connecting two large cylinders and two small cylinders in series up and down. The upper lock seat is connected with the lower end face of the upper tool bit through the bottom plate, the lower lock seat is connected with the upper end face of the lower tool bit through the bottom plate, and the upper lock seat and the lower lock seat are arranged in parallel and correspondingly. The upper blade and the lower blade are both of rectangular plate structures, the upper blade and the lower blade are both provided with locking holes corresponding to the buckles on the lock base, and the locking holes are clamping hole structures formed by connecting large round holes matched with large cylinders on the buckles and small long round holes matched with small cylinders on the buckles in parallel. The upper blade and the lower blade are arranged in parallel and are respectively connected with the lock seats on the upper tool bit and the lower tool bit through lock holes.

When the handle is held and the knob is rotated, the knob can drive the telescopic shaft to rotate together through the connecting cylinder and the guide pin, and when the screw head at the lower end of the telescopic shaft rotates in the screw hole on the handle and rises spirally, the telescopic shaft can drive the upper cutter head and the lower cutter head to be separated in parallel under the combined action of the guide pin and the guide groove. When the upper cutter head and the lower cutter head are vertically separated, beard residues can be conveniently removed, the upper cutter blade and the lower cutter blade can be conveniently replaced, and meanwhile, the upper cutter head can be independently used for shaving longer beards.

When the upper blade or the lower blade is installed, the buckles on the lock seat respectively penetrate through the large round holes of the lock holes on the upper blade or the lower blade, then the upper blade or the lower blade is transversely pushed, and when the small cylinders of the buckles on the lock seat respectively enter the small long round holes on the upper blade or the lower blade, the upper blade or the lower blade can be locked.

The upper cutter head can be moved downwards by reversely rotating the knob, and short and shallow beards can be shaved in a traditional mode when the upper cutter head and the lower cutter head are folded.

The invention has the advantages that the distance between the blades can be adjusted, and the distance between the blades is increased, thereby being convenient for shaving longer beards and removing beard residues accumulated between the blades.

Detailed Description

In fig. 1, 2, 5, 7, 8, and 9, the handle 6 is a cylindrical structure, a screw hole is formed in the central axis of the handle 6, a limit groove 14 is formed in the outer cylindrical wall of the upper end of the handle 6, and the limit groove 14 is a groove surrounding the outer cylindrical wall of the handle 6. The knob 4 is of an annular cylinder structure, and the knob 4 is sleeved on the upper end head of the handle 6 and is matched and positioned with the limiting groove 14 through the limiting pin 5. The connecting cylinder 3 is arranged above the knob 4 and is connected with the knob 4 through a lower end head, and an inner hole of the connecting cylinder 3 is communicated with a screw hole on the handle 6. The lower end shaft head of the telescopic shaft 11 is set to be a screw head 12, a longitudinal guide groove 13 is formed in the middle of the telescopic shaft 11, and the guide groove 13 is an oblong through hole vertically penetrating through the telescopic shaft 11. The telescopic shaft 11 is arranged in the connecting cylinder 3 and is in threaded connection with a screw hole on the handle 6 through a screw head 12 at the lower end, and the guide pin 9 is arranged in a guide groove 13 and is respectively connected with through holes arranged on the left and right side cylinder walls of the connecting cylinder 3 through the left and right ends. The upper tool bit 1 and the lower tool bit 2 are both rectangular plate structures, the upper tool bit 1 is connected with the upper end of the telescopic shaft 11 through a connecting rod, the lower tool bit 2 is connected with the upper end of the connecting cylinder 3 through a connecting rod, and the upper tool bit 1 and the lower tool bit 2 are arranged in parallel and perpendicular to the handle 6. The lock seat 10 is composed of a rectangular bottom plate and a plurality of buckles vertically connected to the bottom plate, and the buckles are of a T-shaped cylinder structure formed by connecting a large cylinder and a small cylinder in series. The upper lock base 10 is connected with the lower end face of the upper tool bit 1 through a bottom plate, the lower lock base 10 is connected with the upper end face of the lower tool bit 2 through a bottom plate, and the upper lock base 10 and the lower lock base 10 are arranged in parallel and correspondingly. The upper blade 7 and the lower blade 8 are both in rectangular plate structures, the upper blade 7 and the lower blade 8 are both provided with locking holes 15 correspondingly matched with the buckles on the lock base 10, and the locking holes 15 are clamping hole structures formed by connecting large round holes matched with large cylinders on the buckles in parallel and small long round holes matched with small cylinders on the buckles in parallel.
