Thus, left and right ends of the engagement member <NUM> are engaged with the corresponding engagement hole <NUM> respectively, thereby engaging the interconnect structure <NUM> with the handle <NUM>.

Thus, the left end of the engagement member <NUM> is engaged with the left engagement hole <NUM> and the right end of the engagement member <NUM> is engaged with the right engagement hole <NUM>, so as to realize the connection between the handle <NUM> and the interconnect structure <NUM>. That is, the connection between the handle <NUM> and the interconnect structure <NUM> is realized by a multi-point engagement on the left and right sides, so the connection structure between the handle and the interconnect structure is complicated.

European patent application <CIT> discloses a connector for matching with a razor handle, such a connector has a connector body with a latch provided. The latch is shaped and configured to extend from the connector body to protrude into the receiving hole. However the connector is to be improved for the stability.

Therefore, there is an urgent need for an interconnecting member and a handle that are able to simplify the structure and mounting process and achieve single-point engagement to overcome the aforementioned deficiencies.

One objective of the present invention is to provide an interconnecting member for a razor which simplifies the structure and the mounting process and achieves stable fastening by single-point engagement.

The accompanying drawings facilitate an understanding of the various embodiments of this invention. In such drawings:.

A distinct and full description of the technical solution of the present invention will follow by combining with the accompanying drawings.

Referring to <FIG> and <FIG>, the interconnecting member <NUM> of the present application is inserted into the handle <NUM> to facilitate the assembly and disassembly between the interconnecting member <NUM> and the handle <NUM>. In order to facilitate the disassembly between the interconnecting member <NUM> and the handle <NUM>, the handle <NUM> is provided with an unlocking operating member <NUM>, but it is not limited to it.

Referring to <FIG>, the interconnecting member <NUM> includes a housing <NUM>, pivoting support arms <NUM> extending upwards from left and right sides of the housing <NUM> respectively, and a resilient engaging arm <NUM> extending upward from the front side of the housing <NUM>. The housing <NUM> is provided with a receiving cavity <NUM> inside, and the receiving cavity <NUM> penetrates an upper end face <NUM> and a lower end face <NUM> of the housing <NUM> so that the handle <NUM> can be inserted into the receiving cavity <NUM> from the lower end face <NUM>. A free end <NUM> of the resilient engaging arm <NUM> is bent toward a rear side of the housing <NUM> and located in the receiving cavity <NUM>. Specifically, the free end <NUM> of the resilient engaging arm <NUM> has an upper surface <NUM>, a lower surface <NUM>, and an inclined surface <NUM> connected between the upper surface <NUM> and the lower surface <NUM> and formed on a rear side of the free end <NUM>. The inclined surface <NUM> is inclined forward from bottom to top of the free end <NUM>. On the one hand, it is convenient for an inserting portion <NUM> of the handle <NUM> described below to smoothly pass through an intersection <NUM> of the inclined surface <NUM> and the lower surface <NUM> and then abut against the inclined surface <NUM> while the inserting portion <NUM> inserts into the receiving cavity <NUM>. On the other hand, the inclined surface <NUM> is in contact with a surface of the inserting portion <NUM>, so that the inclined surface <NUM> stops the inserting portion <NUM> from being pulling-out, thereby effectively preventing accidentally disengage the inserting portion <NUM> from the free end <NUM> of the resilient engaging arm <NUM>. Specifically, the intersection <NUM> between the inclined surface <NUM> and the lower surface <NUM> and an intersection <NUM> between the inclined surface <NUM> and the upper surface <NUM> are arc-shaped to realize a smooth transition. Therefore, while the inserting portion <NUM> inserts into the receiving cavity <NUM>, the inserting portion <NUM> can smoothly pass the intersection <NUM> between the inclined surface <NUM> and the lower surface <NUM>, and then abuts against the inclined surface <NUM>. By means of the intersection <NUM> between the inclined surface <NUM> and the upper surface <NUM>, the upper surface <NUM> will not obstruct the surface contact between the inclined surface <NUM> and the inserting portion <NUM>, thereby further ensuring the reliability of the surface contact between the inclined surface <NUM> and the inserting portion <NUM>. According to the invention, the upper surface <NUM> and the lower surface <NUM> are arcuate surfaces, and the arc diameter of the upper surface <NUM> is greater than the arc diameter of the lower surface <NUM>, so that the free end <NUM> forms the convex arc structure described above. Understandably, according to actual needs, the intersection <NUM> between the inclined surface <NUM> and the lower surface <NUM> or the intersection <NUM> between the inclined surface <NUM> and the upper surface <NUM> is arc-shaped to realize a smooth transition, so it is not limited thereto.

Referring to <FIG> and <FIG> again, according to the invention the housing <NUM> is extended upward to from a left surrounding arm <NUM> and a right surrounding arm <NUM>, respectively. The left surrounding arm <NUM> surrounds the receiving cavity <NUM> on the left side of the housing <NUM>, and the right surrounding arm <NUM> surrounds the receiving cavity <NUM> on the right side of the housing <NUM>. The resilient engaging arm <NUM> surrounds the receiving cavity <NUM> on the front side of the housing <NUM> and is spaced apart between the left surrounding arm <NUM> and the right surrounding arm <NUM>. In this way, the receiving cavity <NUM> forms a flat and narrow cavity, so that the inserting portion <NUM> fits better with the receiving cavity <NUM>. Specifically, the pivoting support arm <NUM> on the left side of the housing <NUM> is arranged on the left side of the left surrounding arm <NUM> at intervals, and the pivoting support arm <NUM> on the right side of the housing <NUM> is arranged on the right side of the right surrounding arm <NUM> at intervals. Therefore, the razor head assembled on the pivoting support arms <NUM> will not interfere with the left surrounding arm <NUM> and the right surrounding arm <NUM> respectively during pivoting, thereby ensuring the reliability of the razor head pivoting.

As shown in <FIG> and <FIG>, the handle <NUM> is provided with the inserting portion <NUM> matched with the receiving cavity <NUM>, and the inserting portion <NUM> is provided with an engaging groove <NUM>. A notch 211a of the engaging groove <NUM> is formed in a front surface 21a and an upper surface 21b of the inserting portion <NUM>, and a rear groove wall 211b of the engaging groove <NUM> is inclined forward from bottom to top of the handle <NUM>, such that the rear groove wall 211b matches the inclination of the inclined surface <NUM> and abuts against the inclined surface <NUM>. When the rear groove wall 211b of the engaging groove <NUM> abuts against the inclined surface <NUM>, the intersection <NUM> between the inclined surface <NUM> and the lower surface <NUM> is located in a space <NUM> between the rear groove wall 211b and a lower groove wall 211c of the engaging groove <NUM>, as shown in <FIG>. Specifically, the rear groove wall 211b and the lower groove wall 211c of the engaging groove <NUM> are both planes and the angle between the two is an acute angle. A left groove wall 211e and a right groove wall 211f of the engaging groove <NUM> are arranged obliquely from bottom to top of the handle <NUM> and approach each other, so that the free end <NUM> of the resilient engaging arm <NUM> is smoothly inserted into the engaging groove <NUM> during the insertion of the inserting portion <NUM> into the receiving cavity <NUM>. Besides, the left groove wall 211e and the right groove wall 211f are combined to effectively prevent the free end <NUM> of the resilient engaging arm <NUM> from swinging left and right. In order that the inserting portion <NUM> can easily and smoothly pass over the intersection <NUM> between the inclined surface <NUM> and the lower surface <NUM>, the rear groove wall 211b of the engaging groove <NUM> obliquely extends forward and upward to form a protruding pushing portion 211d having the same thickness, but it is not limited to it.

As shown in <FIG> and <FIG>, the unlocking operating member <NUM> includes a press part <NUM> slidably disposed on the handle <NUM> and a pushing rod <NUM> connected to the press part <NUM>. The pushing rod <NUM> is inserted into the inserting portion <NUM>, and the pushing rod <NUM> further extends into the engaging groove <NUM> and is located below the free end <NUM> of the resilient engaging arm <NUM>, so that when a user presses the press part <NUM>, the pushing rod <NUM> along with the press part <NUM> slides relative to the handle <NUM>. Subsequently, the pushing rod <NUM> pushes the free end <NUM> of the resilient engaging arm <NUM> to generate resilient deformation, so as to disengage from the engaging groove <NUM> of the inserting portion <NUM>, thereby disengaging the free end <NUM> of the resilient engaging arm <NUM> from the engaging groove <NUM> of the inserting portion <NUM>. Preferably, the press part <NUM> and the pushing rod <NUM> are slidably arranged along a vertical direction of the handle <NUM>. Thus, when the press part <NUM> is slid in the direction indicated by the arrow next to the press part <NUM> in <FIG>, the pushing rod <NUM> slides along with the press part <NUM>, so the free end <NUM> of the resilient engaging arm <NUM> is pushed by the pushing rod <NUM> to resilientally deform in the direction indicated by the arrow C in <FIG>, thereby disengaging the free end <NUM> from the engaging groove <NUM> of the inserting portion <NUM> so as to remove the interconnecting member <NUM> from the handle <NUM>.

With reference to <FIG>, the engagement process of the handle <NUM> with the interconnecting member <NUM> is illustrated. As shown in <FIG>, the handle <NUM> is inserted into the receiving cavity <NUM> of the interconnecting member <NUM> in a direction indicated by the arrow beside the inserting portion <NUM> until an end of the protruding pushing portion 211d of the inserting portion <NUM> abuts against the intersection <NUM> between the inclined surface <NUM> and the lower surface <NUM>. When the end of the protruding pushing portion 211d abuts against the intersection <NUM>, the inserting portion <NUM> continues to be inserted into the receiving cavity <NUM> along its original direction, so that the free end <NUM> of the resilient engaging arm <NUM> is resilientally deformed in the direction indicated by the arrow C in <FIG> by the end of the protruding pushing portion 211d, as shown in <FIG>. As a result, the intersection <NUM> will not block the end of the protruding pushing portion 211d of the inserting portion <NUM>, so as to allow the end of the protruding pushing portion 211d to pass over the intersection <NUM>. Accordingly, the intersection <NUM> enters the engaging groove <NUM> from the notch 211a of the engaging groove <NUM>. Further, under the action of the elastic force of the resilient engaging arm <NUM>, the intersection <NUM> slides along the rear groove wall 211b of the engaging groove <NUM> during the insertion of the inserting portion <NUM> into the receiving cavity <NUM> until the inclined surface <NUM> abuts against the rear groove wall 211b, as shown in <FIG>.

In comparison with the prior art, the resilient engaging arm <NUM> is extended upward from the front side of the housing <NUM>, the free end <NUM> of the resilient engaging arm <NUM> is bent toward the rear side of the housing <NUM> and located in the receiving cavity <NUM>. Furthermore, the free end <NUM> of the resilient engaging arm <NUM> has the upper surface <NUM>, the lower surface <NUM>, and the inclined surface <NUM> connected between the upper surface <NUM> and the lower surface <NUM> and formed on the rear side of the free end <NUM>, and the inclined surface <NUM> is inclined forward from bottom to top of the free end <NUM>. Therefore, while the inserting portion <NUM> of the handle <NUM> is inserted into the receiving cavity <NUM>, the inserting portion <NUM> pushes the free end <NUM> of the resilient engaging arm <NUM> to resiliently deform towards the front side of the housing <NUM>. Specifically, the protruding pushing portion 211d of the inserting portion <NUM> pushes the free end <NUM> of the resilient engaging arm <NUM> to resiliently deform towards the front side of the housing <NUM>, so that the rear groove wall 211b of the engaging groove <NUM> smoothly passes over the intersection <NUM> of the inclined surface <NUM> and the lower surface <NUM> and is in surface-to-surface contact with the inclined surface <NUM>. As a result, the inserting portion <NUM> is reliably clamped between the inclined surface <NUM> and the corresponding cavity wall of the receiving cavity <NUM>, and the inclined surface <NUM> of the free end <NUM> is in surface-to-surface contact with the inserting portion <NUM>. Therefore, the interconnecting member <NUM> is connected to the handle <NUM> by means of one resilient engaging arm <NUM> extending from one side of the housing <NUM>. Consequently, the razor can simplify the structure, and the single-point engagement between the handle <NUM> and the interconnecting member <NUM> can be realized under the premise of ensuring the reliable engagement of the handle <NUM> and the interconnecting member <NUM>.

Notably, if the above-mentioned resilient engaging arm <NUM> is formed by extending upward from the rear side of the housing <NUM>, the free end <NUM> of the resilient engaging arm <NUM> will be bent toward the front side of the housing <NUM> and located in the receiving cavity <NUM>, so it is not limited to the above-mentioned embodiment. When the resilient engaging arm <NUM> extends upward from the rear side of the housing <NUM>, the notch 211a of the engaging groove <NUM> is formed on a rear surface and the upper surface 21b of the inserting portion <NUM>. A front groove wall of the engaging groove <NUM> is inclined rearwards from bottom to up of the handle <NUM>, the front groove wall of the engaging groove <NUM> abuts against the inclined surface <NUM>, and the intersection <NUM> between the inclined surface <NUM> and the lower surface <NUM> is located in a space between the front groove wall and the lower groove wall 211c of the engaging groove <NUM>.

Notably, when the razor shaves beard downward, the side of the interconnecting member <NUM> facing the skin is referred to as the front side, and the side of the interconnecting member <NUM> away from the skin is referred to as the rear side. At this time, the side of the interconnecting member <NUM> on the left side is referred to as the left side, and the side of the interconnecting member <NUM> on the right side is referred to as the right side. And, the side of the interconnecting member <NUM> on the upper side is referred to as the upper end of the interconnecting member <NUM>, and the side of the interconnecting member <NUM> on the lower side is referred to as the lower end of the interconnecting member <NUM>.
