[0030] Specifically, the adjusting device 3 and the wire clamping device 4 are described as follows.

[0031] Referring to Figure 2 , Figure 3 and Figure 4As shown, in the embodiment: the adjusting device 3 comprises two fixed blocks 31, both of which are fixedly connected with the display screen body 1 on the side close to the connector 2, both sides of the display screen body 1 are slidably connected with support frames 32, the surfaces of the support frames 32 are provided with two sliding grooves, the inner surfaces of the sliding grooves of the two support frames 32 are slidably connected with the two fixed blocks 31 respectively, both sides of the fixed blocks 31 away from each other are fixedly connected with fixed rods 33, the arc surfaces of the fixed rods 33 are slidably connected with operation plates 34, the side of the operation plate 34 close to the fixed block 31 is fixedly connected with a plug rod 35, both sides of the support frame 32 are provided with a plurality of plug slots, the end of the fixed rod 33 away from the fixed block 31 is fixedly connected with a limiting plate 36, the size of the plug rod 35 is matched with the size of the plug slot of the support frame 32, when the staff pulls the operation plate 34, the operation plate 34 slides on the arc surface of the fixed rod 33, at this time the limiting plate 36 achieves the effect of limiting the maximum sliding distance of the operation plate 34 on the arc surface of the fixed rod 33, avoiding the situation that the operation plate 34 is separated from the arc surface of the fixed rod 33 due to the large pulling force when the staff pulls the operation plate 34, thereby affecting the normal use of the staff, the arc surface of the fixed rod 33 is sleeved with a first spring 37, both ends of the first spring 37 are fixedly connected with the operation plate 34 and the fixed block 31 respectively, when the staff releases the operation plate 34, the rebound force of the first spring 37 drives the operation plate 34 to slide on the arc surface of the fixed rod 33, at the same time the operation plate 34 drives the plug rod 35 to move until the plug rod 35 is inserted into the plug slot of the support frame 32, at this time the first spring 37 improves the stability of the plug rod 35 limiting the fixed block 31, avoiding the situation that the operation plate 34 is unconsciously slid on the arc surface of the fixed rod 33 due to the influence of the detection shaking of the display screen body 1 when the staff detects the electronic element, thereby causing the plug rod 35 to be forced to separate from the plug slot of the support frame 32, one side of the support frame 32 is fixedly connected with two screw rods 38, the arc surfaces of the screw rods 38 are threadedly connected with protection plates 39, after the staff slides the fixed block 31 into the sliding groove of the support frame 32, the protection plate 39 is rotated to make the protection plate 39 threadedly rotate on the arc surface of the screw rod 38 until the protection plate 39 blocks one side of the sliding groove of the support frame 32, at this time the effect of preventing the sliding block from separating from the sliding groove of the support frame 32 is achieved, avoiding the situation that the staff adjusts the display screen body 1, due to the vision on the electronic element detection data displayed on the display screen body 1, the staff does not find the sliding position of the fixed block 31 in the sliding groove of the support frame 32 in the first time, thereby causing the fixed block 31 to be pulled out of the sliding groove of the support frame 32 by the staff.

[0032] Referring to Figure 2 and Figure 5As shown, specifically, the wire clamping device 4 includes a U-shaped frame 41 fixedly connected with the inner surface of the support frame 32, a driving rod 42 threadedly inserted in the U-shaped frame 41, a clamping plate 43 rotatably connected to one end of the driving rod 42, a soft pad 44 fixedly connected to the side of the clamping plate 43 away from the driving rod 42, and a handle 45 fixedly connected to the end of the driving rod 42 away from the clamping plate 43. When the staff needs to clamp the signal line connected with the connecting port 5, the handle 45 is rotated to drive the driving rod 42 to threadedly move in the U-shaped frame 41, and the driving rod 42 drives the clamping plate 43 to move, and the clamping plate 43 drives the soft pad 44 to move until the soft pad 44 clamps the connected signal line. At this time, the handle 45 achieves the effect of facilitating the staff operation, and the soft pad 44 achieves the effect of reducing the damage to the signal line clamped. The side of the clamping plate 43 close to the driving rod 42 is fixedly connected with a positioning rod 46, and the arc surface of the positioning rod 46 is slidably connected with the U-shaped frame 41. When the staff rotates the handle 45, the handle 45 drives the driving rod 42 to threadedly move in the U-shaped frame 41, and the driving rod 42 drives the clamping plate 43 to move, and the clamping plate 43 drives the soft pad 44 to move, and the clamping plate 43 drives the positioning rod 46 to slide in the U-shaped frame 41 until the soft pad 44 clamps the connected signal line. At this time, the positioning rod 46 achieves the effect of limiting the clamping plate 43 from rotating with the driving rod 42, so as to improve the stability of the soft pad 44 clamping the signal line.

[0033] When the staff needs to adjust the viewing distance of the display screen body 1, the operating plate 34 is pulled to slide on the arc surface of the fixed rod 33, and the first spring 37 is stretched, and the operating plate 34 drives the insertion rod 35 to move until the insertion rod 35 is separated from the insertion slot of the support plate. At this time, the display screen body 1 is pulled to slide on the inner surface of the support frame 32, and the display screen body 1 drives the fixed block 31 to slide in the sliding groove of the support frame 32 until the display screen body 1 is adjusted to the position required by the staff. At this time, the operating plate 34 is released, the rebound force of the first spring 37 drives the operating plate 34 to slide on the arc surface of the fixed rod 33, and the operating plate 34 drives the insertion rod 35 to move until the insertion rod 35 is inserted into the insertion slot of the support frame 32. At this time, the effect of adjusting the viewing distance of the display screen body 1 is achieved, and the situation that the staff with slight myopia has to tilt the body to watch the data of the electronic element test due to the small size of the display screen body 1 or the small data characters displayed on the display screen body 1 is avoided. Thus, the staff can work in a comfortable body posture, the staff's work burden is reduced, and the work efficiency of the staff is improved.

[0034] When the worker needs to clamp the signal line connected with the connecting port 5, the signal line is connected with the connecting port 5 through the U-shaped frame 41, at this time, the handle 45 is rotated, the handle 45 drives the driving rod 42 to screw in the U-shaped frame 41, meanwhile, the driving rod 42 drives the clamping plate 43 to move, the clamping plate 43 drives the soft pad 44 to move, meanwhile, the clamping plate 43 drives the positioning rod 46 to slide in the U-shaped frame 41, until the soft pad 44 clamps the connected signal line, at this time, the effect that the signal line connected with the connecting port 5 is prevented from being kicked off by the worker is achieved, the situation that the signal line is separated from the connecting port 5 to influence the signal receiving of the display screen is avoided when the display screen body 1 is used, the worker's leg is not accidentally kicked to the signal line connected with the connecting port 5, the signal line is not straightened instantaneously, thereby the practicability of the device is improved.
