Description

A finger with controllable bending direction

technical field

The invention relates to a controllable finger, in particular to a controllable bending direction finger.

Background technique

At present, human fingers or existing mechanical fingers can only be bent and straightened to achieve some traditional functions. In the process of continuous development, the existing technology is no longer practical, and it is necessary to break the traditional concept of fingers. Bending and stretching in any number of directions, while completing the functions in different directions; and for the existing mechanical fingers, the manufacturing process is complicated, the cost is high, and the practicability is poor. To solve the above problems, a controllable bending direction has been developed. finger.

To sum up, there are technical problems in the prior art that the manufacturing process of the mechanical finger is complicated, the cost is high, the human finger or the existing mechanical finger can only be bent and straightened, and the practicability is poor.

Contents of the invention

The object of the present invention is to provide a finger with controllable bending direction. The invention has the characteristics of simple manufacture, low cost, controllable flexion and extension in four directions, and good practicability.

The technical scheme of the present invention: a finger with a controllable bending direction, including an elastic shaft, the lower end of the elastic shaft is provided with a fixed end, and the elastic shaft is connected with a group of gyro unit sections through a ring-shaped stop block, and the gyro unit sections are evenly There are four traction holes distributed, and a group of gyro unit sections are provided with pull ropes in the pull holes in the same direction, and the lower ends of the four pull ropes are respectively connected with micro motors.

For the aforementioned finger with controllable bending direction, the outer side of the group of gyro unit sections is provided with a silicone sleeve.

For the aforementioned finger with controllable bending direction, the micro-motor is evenly fixed around the fixed end.

Compared with the prior art, the present invention connects a group of gyro unit sections through the elastic shaft through the ring-shaped limit block. There are four traction holes evenly distributed around the gyro unit section. The traction holes in the same direction of a group of gyro unit sections The pull cord is provided, so that the production is simple and the cost is low; the pull cord is pulled and released by two of the four micro motors facing each other, so that the controllable bending and extension in four directions is realized, and the practicability is good.

In summary, the present invention has the beneficial effects of simple manufacture, low cost, controllable flexion and extension in four directions, and good practicability.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

Example. A finger with a controllable bending direction, as shown in Figure 1-3, includes an elastic shaft 1, the lower end of the elastic shaft 1 is provided with a fixed end 11, and the elastic shaft 1 is connected with a group of gyro unit nodes through a ring-shaped stopper 3 2. There are four traction holes 7 evenly distributed around the gyro unit section 2, a group of gyro unit sections 2 are provided with pull ropes 5 in the traction holes 7 in the same direction, and the lower ends of the four pull ropes 5 are respectively connected with micro motor6.

A silicone sleeve 4 is provided on the outside of the group of gyro unit sections 11 .

The micro motor 6 is evenly fixed around the fixed end 11 .

The working principle of the present invention, by controlling the relative two micro-motors 6 among the four micro-motors 6 on the fixed end 11, one of the micro-motors 6 pulls the pull rope 5, and the relative micro-motors 6 synchronously loosen the stay rope 5 to realize Controllable bending and extension in 4 directions, good practicability; a group of gyro unit sections 2 are connected through the elastic shaft 1 through the annular limit block 3, and the bending is realized through the flexible shaft 1; through a group of gyro unit sections The outer side of 2 is provided with a silicone sleeve 4, which achieves a beautiful effect while bending; a group of gyro unit sections 2 are connected through the elastic shaft 1 through the annular stopper 3, and four traction holes are evenly distributed around the gyro unit section 2 7. A group of gyro unit sections 2 are provided with pull ropes 5 in the traction holes 7 in the same direction, which is easy to manufacture and low in cost.

In the process of use, the present invention can be connected to the bracket 10 according to people's needs, through the bending of the present invention in different directions, different directions can be used to pick up objects in different directions, and can be realized synchronously, as shown in Figure 3 The bread 8 is clamped on the side, the mobile phone 9 is clamped in the middle, and the cup 12 is clamped on the other side.
