By arranging the carrying component, the convenience of carrying the main body 100 is improved.

[0026] like Figure 1-3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the carrying component includes an adjusting screw 110 rotatably connected to the inner wall of the storage box 101, the inner wall of the storage box 101 is fixedly connected to a sliding frame 111, the inner wall of the storage box 101 is slidably connected to a connecting plate 112 through the sliding frame 111, the connecting plate 112 is threadedly connected to the adjusting screw 110, and the side wall of the connecting plate 112 is fixedly connected to a winding box 113, and the winding box 113 is symmetrically arranged in two groups about the central axis of the connecting plate 112. By setting the adjusting screw 110, the winding box 113 can be moved through the connecting plate 112, thereby preventing the operator from being obstructed when using the oscilloscope, and making it more convenient to use.

[0027] like Figure 1-4As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the inner wall of the winding box 113 is fixedly connected with a fixed plate 114, and two groups of fixed plates 114 are symmetrically arranged about the central axis of the winding box 113, and the side wall of the fixed plate 114 is rotatably connected with a winding shaft 115, and the side wall of the fixed plate 114 is fixedly connected with a torsion spring 116, and the end of the torsion spring 116 away from the fixed plate 114 is also fixedly connected to the winding shaft 115, and the outer walls of the two groups of winding shafts 115 are connected with a group of stretching belts 117. By arranging the torsion spring 116 and the winding shaft 115 in coordination, it is convenient to automatically wind up the stretching belt 117, and the applicability is stronger.

[0028] like Figure 1-5 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the supporting component includes a rotating frame 122 fixedly connected to the bottom wall of the main body 100, and the side wall of the rotating frame 122 is rotatably connected to the support leg 120, and the support leg 120 is symmetrically arranged in two groups about the central axis of the main body 100, and the side wall of the support leg 120 is fixedly connected to the limiting plate 121, and the limiting plate 121 is symmetrically arranged in two groups about the central axis of the support leg 120. The side wall of the limiting plate 121 is provided with a telescopic groove 123. By arranging the support leg 120, the main body 100 can be supported, which is beneficial to extending the service life of the main body 100.

[0029] like Figure 1-5 As shown, as a preferred embodiment, on the basis of the above method, further, the inner wall of the telescopic slot 123 is slidably connected with a card plate 124, and the side wall of the card plate 124 is fixedly connected with a spring 125.

The first fixed slot 126 and the second fixed slot 127 can be used to limit the support leg 120, which is more practical.

[0030] Specifically, when the portable digital oscilloscope is in use: when the main body 100 needs to be carried, first, the connecting plate 112 is driven to move out of the storage box 101 through the sliding frame 111 by rotating the adjusting screw 110, and the winding box 113 is driven to move synchronously, and the stretching belt 117 is driven to extend out of the extension slot 102 through the winding box 113, and then the operator pulls the stretching belt 117 to pull the stretching belt 117 out from the winding shaft 115, and then after passing the arm through the stretching belt 117, the winding shaft 115 is driven to wind up the stretching belt 117 through the torsion springs 116 on the upper and lower sides, so that the stretching belt 117 can be more closely fitted to the operator, and then the above steps are repeated to put the other arm into the stretching belt 117 on the other side. At the same time, under the action of the sponge pad 103, the relief of the operator's back skin can be improved, so that other devices can be carried by both hands while the main body 100 is carried. When the main body 100 is carried to the place where it is needed, By removing the main body 100 from the back, the pulled-out stretching belt 117 can be rolled up under the action of the torsion spring 116, and then the adjusting screw 110 is rotated to drive the connecting plate 112 to store the winding boxes 113 on both sides into the storage box 101, so as to prevent the main body 100 from being inconvenient for the operator to use, and then the clamping plates 124 on both sides are pressed to slide out from the first fixing groove 126 and retract into the telescopic groove 123, and then the supporting leg 120 is rotated downward to adjust the supporting leg 120. When it reaches a vertical state, the clamping plate 124 bounces into the second fixing groove 127 under the action of the spring 125, thereby fixing the supporting leg 120, and then repeating the above steps to adjust the supporting leg 120 on the other side to a vertical state, thereby supporting the main body 100, thereby reducing the wear of the ground on the bottom of the main body 100 and increasing the service life of the main body 100. When the main body 100 needs to be moved a short distance, the handle 105 can be rotated to move the main body 100, which is more practical.
