[0002] In the process of debugging equipment, auxiliary debugging is usually performed by using a computer to monitor real-time debugging data. When the debugger is located at a position higher than the computer bracket for debugging, the height of the computer bracket needs to be adjusted. When the debugger is located at a position lower than the computer bracket for debugging, such as when the debugger needs to squat to debug the bottom of the equipment, the existing computer bracket is not convenient for the debugger to view the display screen in real time, thereby reducing the debugging efficiency. In addition, during debugging, it is usually necessary to use a cable to connect the debugging device to the computer. When the debugger accidentally pulls the cable while walking, the cable can easily cause the computer and the bracket to fall to the ground together, so that the computer hits the ground and causes damage to the computer.

[0020] The protection component includes a second elastic member 203 and a driving member 204; the block 7 is arranged to be slidably connected with the adjacent clamping plate 6; a second elastic member 203 is fixedly connected between each block 7 and the adjacent clamping plate 6, and the second elastic member 203 is a spring; two front-to-back symmetrical driving members 204 are fixedly connected to each clamping plate 6, and the driving member 204 is an electric push rod; a pressure sensor is arranged on the telescopic end of the driving member 204; the center of each driving member 204 is aligned with the center of the adjacent block 7.

[0021] The protection assembly also includes a second motor 205, a rotating rod 206 and a protection rod 207; each clamp 6 is fixedly connected to a second motor 205; each output end of the second motor 205 is fixedly connected to a rotating rod 206; each rotating rod 206 is connected to a protection rod 207 via a torsion spring.

[0022] Furthermore, when the debugging personnel are located at a position higher than the computer 8 to perform debugging work, in order to prevent the slide bar 3 from sliding downward, a locking rod 2001 is provided on the support rod 2.

[0023] Furthermore, in order to reduce the resistance when the computer 8 is separated from the debugging cable, the support rod 2 is configured to be rotatably connected to the base 1.

[0024] Furthermore, in order to prevent the debugging cable from being squeezed when the clamping plate 6 hits the ground, causing damage to the debugging cable, a groove 6001 is provided on each clamping plate 6.

[0025] Furthermore, in order to prevent the display screen 8001 from being damaged due to pressure, each block 7 is provided with a pressing portion 7001, and the pressing portion 7001 is made of elastic material.

[0026] The specific work of this embodiment is: First, the two clamping plates 6 are manually pulled to move toward opposite sides, so that the telescopic rod 5001 is extended from the sleeve rod 5, and the spring between the telescopic rod 5001 and the sleeve rod 5 is stretched. At the same time, the two clamping plates 6 move away from each other, driving the corresponding card blocks 7 to move away from each other, until the distance between the card blocks 7 on the left and right sides is larger than the width of the left and right sides of the computer 8. At this time, the display screen 8001 of the computer 8 is unfolded and placed on the fixing plate 4, and then the two clamping plates 6 are loosened, and the telescopic rod 5001 is retracted into the sleeve rod 5, so that the two clamping plates 6 move toward each other, thereby driving the corresponding card blocks 7 to move toward each other, so that the card blocks 7 are respectively stuck on the left and right sides of the computer 8, so as to fix the computer 8. At the same time, the display screen 8001 is unfolded and fits with the rotating rod 206; When the computer 8 needs to be used for debugging, the base 1 is first placed near the debugging location, and one end of the debugging cable is connected to the device that needs to be debugged, and the other end is connected to the left or right side of the computer 8. When the debugger is located at a position higher than the computer 8 for debugging, the distance between the computer 8 and the debugger is far, which is not convenient for the debugger to watch the display screen 8001. Therefore, the slide bar 3 is pulled upward to move the fixed plate 4 and the computer 8 upward, thereby shortening the distance between the computer 8 and the debugger. At the same time, the height of the slide bar 3 is locked by the locking rod 2001 to prevent the slide bar 3 from sliding down. When the debugger squats on the ground to debug the bottom of the equipment, the debugger needs to stand up to watch the display screen 8. 001, it is not convenient for the debugging personnel to watch the display screen 8001 in real time. Therefore, based on the view from left to right, the first motor 201 is controlled to drive the fixing plate 4 to rotate clockwise, so that the computer 8 is tilted clockwise, and the computer 8 is fixed on the fixing plate 4 by the clamping block 7 to prevent the computer 8 from sliding off the fixing plate 4 when tilted. At the same time, the display screen 8001 is tilted toward the ground, so that it is convenient for the debugging personnel squatting on the ground to watch the display screen 8001. On this basis, based on the view from left to right, the second motor 205 is controlled to drive the rotating rod 206 to rotate clockwise, so that the protection rod 207 drives the display screen 8001 to rotate clockwise, so that the display screen 8001 is tilted toward the ground, which is further convenient for the debugging personnel to observe the display screen 8001. When the debugging personnel pull the debugging cable, the debugging cable drives the computer 8 to move to the right, thereby causing the fixing plate 4 to fall to the right, and then causing the clamping plate 6 to collide with the ground, causing the computer 8 to vibrate and cause damage to the computer 8. For this reason, when the debugging personnel pull the debugging cable, the debugging cable drives the computer 8 to move to the right, thereby causing the computer 8 to push the right-side clamping block 7 to move to the right, and the second elastic member 203 is compressed. At the same time, the telescopic end of the driving member 204 contacts the clamping block 7. At this time, the computer 8 pushes the clamping block 7 to continue to move to the right, thereby driving the right-side clamping plate 6 to move to the right, and causing the left-side clamping plate 6, the sleeve rod 5 and the telescopic rod 5001 to move to the right synchronously, thereby causing the right-side first elastic member 202 to be stretched, and the left-side first elastic member 202 to be compressed, thereby increasing the resistance of the computer 8 to move to the right, thereby reminding the debugging personnel to pull the debugging cable at this time. On this basis, when the left-side clamping plate 6 and the fixed plate 4 are When the left side of the fixed plate 4 is in contact, the right clamping plate 6 is restricted and stops moving to the right. At this time, the debugging cable continues to pull the computer 8 to move to the right, so that the card block 7 squeezes the driving member 204 to the right, and the pressure on the telescopic end of the driving member 204 is detected by the pressure sensor. When the pressure reaches the preset threshold of the pressure sensor, the telescopic end of the driving member 204 is controlled to move to the left by sending an electrical signal, thereby pushing the card block 7 to move to the left, so that the card block 7 pushes the computer 8 to move to the left, so that the moving direction of the computer 8 is opposite to the moving direction of the debugging cable, thereby facilitating the separation of the debugging cable from the computer 8, and preventing the debugging cable from continuing to pull the computer 8 and causing the fixed plate 4 to tip to the right, thereby causing damage to the computer 8. On this basis, when there is an angle between the pulling direction of the debugging cable and the central axis of the computer 8, by setting the support rod 2 to be rotatably connected to the base 1, the fixing plate 4 can be adaptively rotated while the debugging cable pulls the computer 8, so that the pulling direction of the debugging cable is parallel to the central axis of the computer 8, thereby reducing the resistance when the computer 8 is separated from the debugging cable; When the debugging cable is too tightly connected to the computer 8, it is difficult to separate the computer 8 from the debugging cable by moving the clamping block 7 in the opposite direction. At this time, the fixing plate 4 tilts to the right side under the pull of the debugging cable, so that the right clamping plate 6 hits the ground first, so that the right clamping plate 6 fits to the right side of the fixing plate 4. At the same time, the first elastic member 202 on the right side is compressed and the first elastic member 202 on the left side is stretched. The first elastic member 202 absorbs the vibration generated by the clamping plate 6 hitting the ground, thereby reducing the probability of the computer 8 being subjected to large vibrations and causing a malfunction. On this basis, when the computer 8 tilts to the right, the display screen 8 001 is in the unfolded state, which makes it easy for the display screen 8001 to be squeezed by objects on the ground, thereby damaging the display screen 8001. Therefore, when the fixing plate 4 tilts to the right, based on the view from left to right, the electrical signal sent by the pressure sensor controls the second motor 205 to drive the rotating rod 206 to rotate clockwise, so that the protection rod 207 drives the display screen 8001 to rotate clockwise until the display screen 8001 is in contact with the rear extrusion part 7001, and stops rotating, so that the display screen 8001 is covered toward the fixing plate 4 side, avoiding the display screen 8001 being squeezed by objects on the ground and causing damage to the display screen 8001; When the clamping plate 6 hits the ground, the debugging cable is between the clamping plate 6 and the ground, so that the debugging cable is easily damaged by the impact. Therefore, based on the view from left to right, when the protection rod 207 drives the display screen 8001 to rotate clockwise until the extrusion part 7001 is in contact, the display screen 8001 stops rotating, thereby preventing the protection rod 207 from continuing to rotate clockwise. At this time, the second motor 205 continues to drive the rotating rod 206 to rotate clockwise, thereby deflecting the protection rod 207. Based on the view from front to back, the protection rod 207 on the right side rotates clockwise, and the gap between the protection rod 207 and the rotating rod 206 is The torsion spring is stressed, causing the protection rod 207 to disengage from the display screen 8001. At this time, the rotating rod 206 continues to rotate clockwise until the rotating rod 206 and the splint 6 are parallel. At this time, the rotating rod 206 contacts and squeezes the debugging cable, so that the debugging cable is in the groove 6001, thereby preventing the debugging cable from being squeezed when the splint 6 hits the ground, causing damage to the debugging cable. On this basis, when the display screen 8001 is in contact with the squeezing part 7001, since the squeezing part 7001 is made of elastic material, the squeezing of the display screen 8001 by the block 7 is reduced, thereby preventing the display screen 8001 from being damaged due to pressure. Example 2

[0027] On the basis of Example 1, Figure 1 and Figure 6-Figure 8 As shown, it also includes an airbag 301; an airbag 301 is installed on the left and right sides of the fixing plate 4 respectively; two left-right symmetrical cavities 4001 are arranged in the fixing plate 4; each airbag 301 is connected to the adjacent cavity 4001; each airbag 301 is in contact with the adjacent clamping plate 6.

[0028] Furthermore, when the splint 6 collides with the ground, in order to prevent impurities such as sand from entering the cooling fan of the computer 8, each cavity 4001 is provided with a first exhaust hole 4002, and each first exhaust hole 4002 is provided with a one-way valve; each airbag 301 is provided with a plurality of second exhaust holes 30101, and each second exhaust hole 30101 is provided with a one-way valve; each splint 6 is provided with an exhaust channel 6002, and each exhaust channel 6002 is connected to the adjacent second exhaust hole 30101.

[0029] Since the computer 8 has its own cooling fan, and the air inlet of the cooling fan is usually on the left or right side of the computer 8, when the fixing plate 4 falls over, the airflow agitated by the fixing plate 4 is likely to cause impurities such as sand and dust on the ground to be lifted up, and then the sand and dust and other impurities are easily sucked into the cooling fan of the computer 8, which may easily cause damage to the cooling fan. For this reason, when the clamping plate 6 collides with the ground, the clamping plate 6 squeezes the airbag 301 in the process of fitting with the fixing plate 4, and the airbag 301 absorbs the vibration generated by the clamping plate 6 colliding with the ground, thereby further reducing the probability of computer 8 malfunctioning due to vibration. At the same time, the airbag 301 is compressed, causing the internal air pressure to increase, and the one-way valve on the second exhaust hole 30101 opens, allowing the gas in the airbag 301 to pass. The air passes through the second exhaust hole 30101 and enters the exhaust channel 6002, and is then blown out from the exhaust channel 6002, thereby forming a small wind curtain blowing upwards at the air inlet of the computer 8, blocking impurities such as sand particles from entering the cooling fan of the computer 8, thereby avoiding damage to the cooling fan and ensuring that the heat dissipation efficiency of the computer 8 is not affected. Subsequently, the debugging personnel lift up the fixing plate 4 and the connecting parts and the computer 8, and reset and move the splint 6 through the first elastic member 202, so that the airbag 301 returns to its initial size, so that the air pressure in the airbag 301 is lower than the external air pressure, and the one-way valve on the first exhaust hole 4002 opens, and the external air enters the airbag 301 through the first exhaust hole 4002, thereby facilitating the next exhaust of the airbag 301.
