Description

Exercise chopsticks

Technical Field

The embodiment of the utility model relates to a chopsticks technical field, concretely relates to exercise chopsticks.

Background

Chopsticks are the most common eating tools in China, and compared with forks and cutters, the chopsticks are more difficult to use, especially for children, the chopsticks can be gradually learned for a while, and the use of training chopsticks can more conveniently teach the children how to use the chopsticks.

The current practice chopsticks are all composed of two chopsticks and a connecting piece 3 hinged with the two chopsticks, the connecting piece 3 connects the two chopsticks together, and simultaneously, the connecting piece is used for keeping the tips of the two chopsticks aligned all the time. When the chopsticks are used for exercise, the two chopsticks rotate around the hinge parts or the sliding parts, so that food can be clamped, and the opening and clamping of the chopsticks can be performed.

As shown in fig. 1, the most common practice chopsticks are provided with a hinge at the top of the first chopstick 1 and the second chopstick 2, the tips of the chopsticks can always keep aligned, and the chopsticks can pick up different sized food by opening the two chopsticks at different angles.

As shown in fig. 2, in the training chopsticks with the publication number CN201831541U, the upper parts of the first chopstick 1 and the second chopstick 2 are hinged by a hinge, and connected by a thin spring at the top part of the two chopsticks, the two chopsticks rotate around the two sides of the hinge respectively, and the tips of the two chopsticks can be always kept aligned to perform the training of opening and clamping the chopsticks.

However, in this case, the two chopsticks are always kept at a constant distance at the hinge, and cannot move transversely at the hinge, and we know that the flexibility of the chopsticks is that when the chopsticks are normally used, each point of the chopsticks can move transversely in order to clamp various foods with different sizes, and the hands can automatically clamp the foods at the most proper angle and with the least force in long-term use. The chopsticks can not move transversely on the hinge and the upper side and the lower side of the hinge, so that a child can pick up food when using the training chopsticks, but can not pick up the food at the most proper angle with the least force. If the connecting piece 3 is not arranged, the tips of the chopsticks are difficult to keep accurate alignment all the time, and children are difficult to use the training chopsticks for effective training, so that the defect is difficult to overcome at present.

As shown in FIG. 3, to solve this problem, in the training chopsticks with the authorized publication number CN208725407U, a first chopstick 1 and a second chopstick 2 are connected with the chopsticks in a relatively sliding manner, the chopsticks are provided with holes, a connecting member 3 is connected with the chopsticks through the holes, the chopsticks at one side are fixed by the elasticity of the connecting member 3, the chopsticks at the other side can slide on the connecting member 3, so that the transverse position of the upper parts of the two chopsticks is changed, in order to ensure the normal rotation of the chopsticks, the sliding part of the connecting member 3 must be inclined with the chopsticks, but if the chopsticks slide on the connecting member 3 when in use, the tips of the chopsticks are difficult to be aligned, which is against the original purpose of design, and can only slide when being installed. So that in use it is difficult to move the two chopsticks laterally at the location of the connecting element 3, which drawback is still difficult to overcome for this application.

We have noticed that when using two chopsticks, one chopstick is clamped at the inner side of the thumb and the index finger, the other chopstick is clamped at the outer side of the thumb and the index finger, the inner chopstick is not moved but only rotates around the clamping part of the fingers, the other chopstick can transversely move at the clamping part of the fingers and simultaneously rotates around the clamping part of the fingers, and how to design a chopstick according to the characteristic of using the chopstick, the position of the connecting element 3 can transversely move according to the force of the fingers and simultaneously can rotate around the connecting element 3, so as to clamp food with the most proper angle and the least force, so as to achieve the best practice effect, is a problem to be solved.
