The top surface of the first arc angle 10 is provided with a through hole 12. The top corner of the opposite surface of the right-hand keyboard 2 and the left-hand keyboard 1 is provided with a second arc angle 20. An avoiding opening 21 is formed in the top end face of the right-hand keyboard 2 and is close to the second arc angle 20, and the avoiding opening 21 is communicated with the inside of the right-hand keyboard 2. The top surface of the second arc angle 20 is provided with a limiting hole 22. The U-shaped wire sleeve 3 is hollow, the top surfaces of two ends of the U-shaped wire sleeve are provided with inserting holes 30, and pins 31 are inserted into the inserting holes 30. The outer side surfaces of the U-shaped wire sleeve 3 close to the two ends are provided with wire guiding ports 32. Two ends of the U-shaped wire sleeve 3 are respectively inserted with the square opening 11 and the avoiding opening 21. The two insertion holes 30 correspond to the through hole 12 and the stopper hole 22, respectively. The top surfaces of the bottom ends of the left-hand keyboard 1 and the right-hand keyboard 2 are respectively provided with a slot 14 and a groove 24. The bottom ends of the left-hand keyboard 1 and the right-hand keyboard 2 are connected with a wrist protecting pad 4. A flat sleeve 41 is bonded at the center of the bottom surface of the wrist protection pad 4, and an L-shaped elastic plate 42 is inserted into the flat sleeve 41.

In this embodiment, the U-shaped wire sheath 3, the flat sheath 41 and the elastic plate 42 are all made of PP material and are integrally formed, so that the U-shaped wire sheath has light weight, good toughness and rigid strength, and is durable.

Furthermore, a lead 13 is inserted into the square opening 11, and the lead 13 is a bus of the key circuit board in the left-hand keyboard 1. The lead 13 penetrates through the lead opening 32 at one end of the U-shaped wire sleeve 3 and penetrates out of the lead opening 32 at the other end, and then penetrates into the avoidance opening 21 to be combined with the circuit of the key circuit board in the right-hand keyboard 2.

Specifically, the through hole 12 is in inserting fit with the pin 31, and the limiting hole 22 is in inserting fit with the pin 31, so that the left-hand keyboard 1 and the right-hand keyboard 2 rotate at two ends of the U-shaped wire sleeve 3.

Specifically, a keyboard bus plug wire 23, which is a combined wire of the wire 13 and a circuit of the key circuit board in the right-hand keyboard 2, is penetrated through one end of the right-hand keyboard 2 away from the second arc angle 20, and is connected to a socket of a computer through the keyboard bus plug wire 23, so that the keyboard is powered on to work.

In addition, the opposite surfaces of the bottom ends of the left-hand keyboard 1 and the right-hand keyboard 2 are respectively embedded with a magnet 15 and an iron sheet 25, and after the left-hand keyboard 1 and the right-hand keyboard 2 are closed, the magnet 15 and the patch 25 are magnetically connected to form a whole body by connecting the left-hand keyboard 1 and the right-hand keyboard 2.

It is worth noting that the wrist pad 4 is wrapped by leather pad and filled with high-density sponge, so that the wrist is comfortable. The hard sheet 40 is adhered to the inner bottom surface of the wrist pad 4 so that the entire wrist pad 4 is not collapsed.

It should be noted that the short edge of the elastic plate 42 is inserted into the slot 14 and the groove 24, so as to facilitate the detachment of the wrist pad 4.

When the programming keyboard which accords with the human engineering design is used, the left-hand keyboard 1 and the right-hand keyboard 2 are simultaneously stirred to two sides, so that the first arc angle 10 of the left-hand keyboard 1 and the second arc angle 20 of the right-hand keyboard 2 deflect around the pin 31, and the first arc angle 10 and the second arc angle 20 are in contact with each other along with the deflection of the left-hand keyboard 1 and the right-hand keyboard 2, so that the interference is avoided; the two keyboards are stabilized at any angle position through the friction force formed by connecting the U-shaped wire sleeve 3 with the square opening 11 and the avoidance opening 21, the movement during use is avoided, when the left-hand keyboard 1 and the right-hand keyboard 2 deflect to the two sides to be vertical to the placing direction of the arm, the wrist and the arm are adjusted to be on the same straight line due to the fact that the hand typing is vertical to the keyboards, and the torsion of the wrist is reduced; the short edges of the two elastic plates 42 are respectively inserted into the slot 14 and the groove 24, the flat sleeve 41 slides on the elastic plates 42 when the wrist protection pad 4 can move back and forth, and stops moving through friction, so that people with different hands can adjust and use conveniently, the wrist is supported, the fatigue of the wrist is relieved, and the elastic plates 42 are plastic products and have certain elasticity, so that when a programmer presses the wrist protection pad 4 to type and program, the elastic plates 42 can be bent and deformed, and the pressure of the wrist can be relieved.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
