Technical Field

The utility model relates to a fitting of a hair cutter, in particular to a head structure of the hair cutter, in particular to a reciprocating shaver head.

Background

As a daily use tool for men, the market razor can be basically divided into 3 types: manual shavers, rotary shavers, reciprocating shavers, wherein a reciprocating shaver has a superior cutting capacity compared to manual and rotary shavers. However, the dimensions of the reciprocating shaving heads are much larger than those of both manual and rotary shavers, often up to 2 times larger than those of both manual and rotary shavers. When the reciprocating shaver is used, the large-area shaver head is clumsy when contacting the face of a human body, and in order to enhance the use feeling, a 2D or 3D floating shaver head design is provided.

The design of the floating cutter head requires a corresponding locking mechanism to stabilize the cutter head, and certainly, the design of the floating cutter head does not require the locking mechanism to directly support the cutter head by using a spring, but the direct spring design has high requirements on the precision of components, and the elasticity of the spring also needs to be adapted. Or the existing locking mechanism is too complicated when being applied to a reciprocating shaver, and the operation is inconvenient.

Detailed Description

Referring to fig. 1-4, a floating cutter head for a reciprocating shaver is disclosed, but the solution of the embodiment is of course also applicable to other hair cutters, such as shavers. The floating cutter head 1 is located on the top of the shaver and is assembled on the cutter head seat 2, and the floating cutter head 1 is connected with the cutter head seat 2 in a swinging way, so-called swinging connection, in this example, specifically, referring to fig. 3 and fig. 4, the floating cutter head 1 can swing on the cutter head seat 2 at a certain angle, which is realized in a way as shown in fig. 1, two ends of the cutter head seat 2 are respectively and fixedly connected with a fixed frame 3 extending towards the floating cutter head 1, a positioning through hole is arranged on the fixed frame 3, a connecting rod 4 connected with the positioning through hole is arranged on the floating cutter head 1, a snap spring 5 used for applying force to the floating cutter head is arranged on the connecting rod, the snap spring 5 is used for limiting the floating cutter head 1 to excessively swing around the positioning, of course, the position selection of the positioning through hole also has influence on the swinging amplitude of the floating cutter head because, the swing space is naturally limited in structural design.

In this embodiment, referring to fig. 1 and 2, a fixed plate 11 is further disposed on the floating tool bit 1 and enters into the tool bit holder 2, a positioning groove 12 with an insertion opening is disposed on the fixed plate 11, an opening direction of the positioning groove 12 is perpendicular to a swing direction of the floating tool bit 1, a toggle switch 6 and a locking rod 7 linked with the toggle switch are disposed on the tool bit holder 2, and the toggle switch 6 pushes or separates the locking rod 7 from the positioning groove insertion opening. The fixing device 11 is a component of the floating tool bit 1, the locking rod 7 is driven to move by toggling the switch 6, the locking rod is pushed into the insertion opening of the positioning groove, the floating tool bit 1 is locked because the direction of the insertion opening is vertical to the swinging direction of the floating tool bit, and the floating tool bit can swing to realize the floating effect only if the locking rod 7 is separated from the insertion opening of the positioning groove. The simple locking mechanism can be directly assembled to the floating tool bit and the tool bit seat, and due to the existence of the locking mechanism, the clamp spring can be selected as a limiting mechanism of the floating tool bit, so that the assembly cost advantage is achieved.

In one embodiment, the toggle switch 6 is located outside the tool bit holder 2, the toggle switch 6 is connected to the rack 61 located inside the tool bit holder, the locking rod 7 is fixed to a rotating gear 71, and the rack 61 is meshed with the rotating gear 71. The toggle switch is connected with a toggle rod between the racks, and the shape of the toggle rod is matched with the shell of the tool bit seat 2. The locking rod 7 can be rotated through the meshing relation of the rack and the gear by the sliding of the toggle switch 6, and then the locking rod can be driven to enter or separate from the positioning groove insertion opening, the operation is simple and convenient, and the design of the toggle lever is used for further saving the limited space in the tool bit seat.

As another embodiment, the toggle switch 6 is located outside the tool tip seat 2, the toggle switch 6 is connected to the rack 61 located inside the tool tip seat, the locking rod 7 is fixed to a turntable 72, the turntable 72 is provided with a gear 71, the gear is rotatably connected inside the tool tip seat, and the rack and the gear are meshed. The toggle switch 6 is connected with a toggle lever between the racks, and the shape of the toggle lever is matched with the shell of the tool bit seat. A rotary disc 72 serving as a connecting member is additionally arranged between the locking rod 7 and the gear 71, and the size of the rotary disc 72 can be adjusted during design so that the locking rod 7 can enter or leave the positioning groove inserting opening conveniently, and obviously, the size of the rotary disc 72 is simpler than that of the gear 72.

In addition to the above preferred embodiments, the present invention has other embodiments, and those skilled in the art can make various changes according to the present invention without departing from the spirit of the present invention, which should fall within the scope defined by the appended claims.
