Circular plates 704 are fixedly connected to both ends of the rotating rod 702, and two torsion springs 705 are sleeved on the surface of the rotating rod 702. Both ends of the two torsion springs 705 are respectively fixedly connected to the arc-shaped plates 701 and the circular plates 704. By providing the circular plates 704, the torsion springs 705 can be conveniently installed. By providing the torsion springs 705, the rotation of the rotating rod 702 can be controlled. By providing the rotating rod 702, the positions of the torsion springs 705 can be restricted.

[0032] On one side of the display 1 close to the circular plate 704, two fixing blocks 707 are fixedly connected. On the side of the two fixing blocks 707 away from the display 1, chutes are provided. On the surface of the chutes of the two fixing blocks 707, sliders 708 are slidably connected. One end of the slider 708 away from the display 1 is fixedly connected to a "U"-shaped plate 706. By providing the fixing blocks 707, the sliders 708 can be connected to the display 1, and the sliders 708 slidably connected to the surface of the chutes of the fixing blocks 707 can move. The inner wall of the slider 708 is slidably connected to a fixing rod 709. The fixing rod 709 is fixedly connected to the surface of the chute of the fixing block 707. A first spring 710 is sleeved on the surface of the fixing rod 709. The two ends of the first spring 710 are fixedly connected to the slider 708 and the display 1 respectively. By providing the fixing rod 709, the position of the first spring 710 can be restricted. By providing the first spring 710, the position of the slider 708 can be restricted.

[0033] As Figure 2 and Figure 5 shown, the buffer device 8 includes a rectangular plate 81. The rectangular plate 81 is fixedly connected to the surface of the connecting line 5. On the side of the rectangular plate 81 away from the display 1, four second springs 86 are fixedly connected. The other ends of the four second springs 86 are fixedly connected to a moving plate 82. The moving plate 82 is sleeved on the surface of the connecting line 5. By providing the rectangular plate 81, the second springs 86 and the moving plate 82 can be installed. By providing the second springs 86 and the moving plate 82, a buffering effect can be achieved when the connecting line 5 is bent.

[0034] One end of the rectangular plate 81 close to the second springs 86 is fixedly connected to four sliding rods 84. The four sliding rods 84 are all slidably connected to the inner wall of the moving plate 82. One end of the four sliding rods 84 away from the rectangular plate 81 is fixedly connected to a limiting plate 85. By providing the sliding rods 84, the position of the second springs 86 can be restricted. By providing the limiting plate 85, the connection relationship between the moving plate 82 and the sliding rods 84 can be ensured as much as possible. A number of balls 83 are rotatably connected to the inner wall of the moving plate 82. The number of balls 83 are all slidably connected to the surface of the connecting line 5. By providing the balls 83, a protective effect can be achieved on the connecting line 5 during the process of controlling the movement of the moving plate 82 when the connecting line 5 is bent.

[0035] Working principle: When using a digital pressure detector for pressure detection, first connect the display 1, the connecting line 5 and the detection head 6 through the connector 4 and the interface 3, start the display 1, and control the pressure detection through the display screen 2. By setting the detection head 6, the pressure situation can be fed back to the display screen 2 in real time, which can ensure the real-time nature of the pressure detection. After using the pressure detector, move the "U"-shaped plate 706 to drive the slider 708 to slide on the surface of the slide groove on the fixed block 707, so that the "U"-shaped plate 706 moves away from the arc plate 701, and then rotate the protective plate 703 to make the rotating rod 702 rotate on the inner wall of the arc plate 701. At this time, the circular plate 704 drives the torsion spring 705 to rotate. After moving the protective plate 703 close to the fixed block 707, release the "U"-shaped plate 706. Under the action of the elastic force of the first spring 710, the slider 708 slides on the surface of the fixed rod 709, so that the "U"-shaped plate 706 moves close to the protective plate 703. The position of the protection plate 703 is restricted. When the digital pressure detector needs to be used, the "U"-shaped plate 706 is moved away from the protection plate 703. At this time, under the action of the elastic force of the torsion spring 705, the protection plate 703 rotates away from the fixed block 707, and then the display screen 2 can be operated. By setting the protection device 7, the display screen 2 of the digital pressure detector can be covered when the digital pressure detector is not in use, so that the display screen 2 can be protected and the damage of the display screen 2 caused by bumps can be avoided as much as possible, thereby ensuring the service life of the digital pressure detector as much as possible.

[0036] When bending the connecting line 5, the bending of the connecting line 5 causes the ball 83 to rotate on the inner wall of the movable plate 82, and at the same time, the connecting line 5 pushes the movable plate 82 to move on the surface of the sliding rod 84, so that it can play a buffering effect when the connecting line 5 is bent. When the bending degree of the connecting line 5 is reduced, under the action of the elastic force of the second spring 86, the movable plate 82 moves away from the rectangular plate 81. By setting the limit plate 85, the connection relationship between the movable plate 82 and the sliding rod 84 can be guaranteed as much as possible. By setting the buffer device 8, the interface 3 of the connecting line 5 of the digital pressure detector can be protected during the use of the digital pressure detector, so that when the connecting line 5 is bent, it can play a buffering effect and avoid the connection between the connecting line 5 and the connector 4 from being broken as much as possible.
