The present invention relates to a two-stage chopsticks, and more particularly, to a two-stage chopsticks having a connecting assembly provided so that the chopsticks can be easily assembled during use and easily dismantled when stored.

A conventional two-stage chopstick is shown in FIG. 4, which includes an upper portion 9. The upper portion 9 is provided with a gripping portion that can be gripped by the user's hand, the corresponding screw hole 81 formed in the lower portion 8 and the screw projection 91 to be screwed. This conventional two-stage chopsticks is configured to allow the user to use after assembling the chopsticks, and to dismantle them after use to facilitate the storage of the chopsticks. However, the chopsticks equipped with such connecting means take considerable effort and time from the user to properly assemble the upper and lower parts 9 and 8 and still take up a relatively large space after dismantling the chopsticks, Accordingly, there is inconvenience in storing such conventional chopsticks.

Another prior art two-stage chopsticks are shown in FIG. 5, which consists of an upper tube 7 and a lower tube 6, the upper tube 7 having a constraining portion 71 and a lower tube. 6 has a corresponding restraining portion 61. Moreover, the lower tube 6 is located inside the upper tube 7 so that the lower tube 6 can slide along the upper tube 7 from the inside. Therefore, when the restraint portions 61 and 71 are engaged with each other, the chopsticks are properly assembled so that the user can use them, and when the lower tube 6 enters the upper tube 7, the chopsticks can be stored. However, these chopsticks may have the advantage of easy storage, but the embedded tube (6, 7) can be a source of bacterial propagation site because it can not be dismantled for cleaning. Moreover, after use for a period of time, the restraint parts 61, 71 may wear out and no longer restraint mutually.

The present invention has been provided in consideration of such a situation. An object of the present invention is to provide a two-stage chopsticks comprising a connection assembly provided in the lower portion of the chopsticks can be easily coupled to the upper portion of the chopsticks. In particular, the connecting assembly provides a self restoring function whereby the connecting assembly can be easily received and constrained in the upper portion. Therefore, by using the connection assembly that can be engaged with the through-hole of the upper portion, the chopsticks according to the present invention achieves the object that can be easily assembled when used and can be easily dismantled when cleaning.

It is still another object of the present invention to provide a two-stage chopsticks with a lid having a plurality of clamping members further provided on the upper portion of the chopsticks and easily stored, wherein the lid is sized to match the upper portion. Since the clamping member is pressed onto the inner wall of the upper portion, one end of the lower portion can be received in the upper portion and the lower portion can be clamped by the clamping member and constrained in the upper portion. Therefore, the physical dimension of the chopsticks of the present invention can be effectively reduced.

To achieve this and other objects of the present invention, the chopsticks of the present invention comprise: a lower portion having one closed end; An upper portion having a lid provided at one end thereof, the lid including a plurality of clamping members for clamping the lower portion; A connecting assembly having a connecting body comprising a first end to be fastened to the lower part and a second end projecting from the lower part, the second end being inserted into the upper part to fasten the fastener set to be fastened to the end. It includes more.

The chopsticks of the present invention can thus be assembled by a fastener set by engaging the lower part to the end of the upper part away from the lid, while the closed end of the lower part to the end of the upper part away from the lid. The physical dimension can also be reduced by inserting into engagement with the clamping member.

Preferred embodiments of the present invention, further objects and advantages of the present invention will be best understood by reading the following detailed description of exemplary embodiments with reference to the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 1 to 3. However, these examples are provided for illustration only and should not be construed as limiting the constitution of the present invention.

The present invention relates to a two-stage chopstick which mainly uses the connecting assembly 3 to couple the upper portion 1 for the handle with the lower portion 2 for the food collector. The lower part 2 and the upper part 1 can be easily assembled and disassembled by the connecting assembly 3. Moreover, the lower part 2 can be clamped by the lid 4 arranged at one end of the upper part 1 and constrained in the upper part 1.

According to the present invention, the upper part 1 is formed of a substantially square tube, and a plurality of ridges 11 provided to restrain the lid 4 at one end and the lower part 2 at the other end are engaged. It includes a through hole 12 provided to roll. The lid 4 is positioned against said one end of the upper portion 1 and is prevented from slipping into the upper portion 1 by a plurality of restraints 41 provided on the lid. The lid 4 also includes a protruding button 42 provided to restrain the lid so that it can be disassembled from the upper part 1. Furthermore, the lid 4 comprises a plurality of restraint grooves 43 which engage with the plurality of ridges 11 of the upper part 1, respectively. In addition, a plurality of C-type clamping members 44 extend from the lid 4.

The lower part 2 is formed of a substantially square tube with a closed end and has a connecting assembly 3 arranged at the other end. The connecting assembly 3 comprises a connecting body 31 which is composed of a first end 311 to be fixedly fastened to the lower part 2 and a second end 312 protruding from the lower part 2. The second end 312 further comprises a fastener set 32 which is inserted into the end of the upper part 1 and which is to be fastened to the end of the upper part 1. The fastener set 32 further includes an elastic component 321, a resistance component 322, and a receiving tube 323 for receiving the elastic component 321 and the resistance component 322. The receiving tube 323 may be mounted onto the second end 312 of the connector 31 and the resistance component 322 may be mounted from the through hole 323A of the receiving tube 323 by the elastic component 321. Can protrude, where the through hole 323A is smaller than the resistive part 322 in the radial direction so that the resistive part 322 can partially pass through the through hole 323A and the through hole of the upper part 1. Can be additionally engaged with (12). According to an embodiment of the present invention, the elastic component 321 may be made of rubber while the resistance component 322 may be made of steel balls.

Thus, when using the chopsticks of the present invention, the connecting assembly 3 can be secured to the upper part 1 at the end away from the lid 4, and the resistance component 322 is attached to the upper part 1. It can engage with the through hole 12, whereby the upper portion 1 and the lower portion 2 are assembled with chopsticks.

While specific embodiments of the invention have been described in detail in an illustrative sense, those of ordinary skill in the art may vary the invention without departing from the scope of the invention as set forth in the claims below. It will be appreciated that modifications and variations can be made.

According to the above-described structure of the present invention, when the chopsticks are to be stored after use as shown in Fig. 2, the lower part 2 is first pulled out of the upper part 1 and the lower end is turned over so that the closed end is forward. By inserting it back into the upper part 1, the closed end of the lower part 2 can be clamped by the clamping member 44, which can effectively reduce the physical dimensions of the chopsticks.
