Detailed Description

In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Example 1

As shown in fig. 1-3, the present embodiment provides a clip type chopstick head, which includes a chopstick head rod body 11 and 4 arc-shaped grooves 12.

In this embodiment, the width of the chopstick head rod body 11 is increased gradually from the head end to the tail end, the cross section of each axial position of the chopstick head rod body 11 is in a similar shape, the small end and the big end structure more accord with the clamping hand shape, and larger axial area can be contacted with objects when clamping the objects, so that preliminary clamping anti-skid force is provided.

In this embodiment, 4 arc recess 12 circumference evenly set up on the chopsticks head body of rod 11 surface, and each arc recess 12 sets up and the one end of arc recess 12 extends to the head end bottom surface of the chopsticks head body of rod 11 along the axial straight line extension of chopsticks head body of rod 11, so when convenience of customers washs chopsticks, slides along chopsticks major axis direction and rubs with the hands and washes, and convenient quick the getting rid of remains the spot, and also conveniently lets oil drip or vegetable juice swift down along arc recess 12 when pressing from both sides the dish, plays certain oil logging effect. Meanwhile, the arc-shaped groove 12 extends to the bottom surface of the head end of the chopstick head rod body 11, so that different axial clamping positions of the chopstick head can exert stable clamping effect, and the chopstick head is particularly suitable for small articles. Preferably, the axial length of the arc-shaped groove 12 is 3 cm-10 cm and is smaller than the length of the chopstick head rod body 11.

In this embodiment, the bottom of each arc groove 12 is parallel to the generatrix of the chopstick head rod body 11, and the two circumferentially adjacent arc grooves 12 are in arc transition, and the radius R of the arc transition part between the two circumferentially adjacent arc grooves 12 and the radius R of the outer ring at the same axial position of the chopstick head rod body 11 satisfy the following formula: R/R = 3.2-3.5. The opening angle of the notch of each arc-shaped groove 12 is 125-150 degrees, the opening angle is that the innermost point of the groove bottom of the arc-shaped groove 12 is used as the vertex of the included angle, and two straight lines of the included angle respectively pass through the connecting points of the groove wall of the arc-shaped groove 12 and the arc transition part. The arc-shaped groove 12 with the structure can realize at least two contact points of one chopstick head, when the two chopstick heads clamp objects, at least four contact points are arranged and the objects are clamped in a bilateral symmetry manner, the contact area is further increased, the clamping force is obviously enhanced, and when stronger force is applied to strip-shaped objects, the strip-shaped objects can be clamped and divided into small sections.
