DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0021] like Figure 1-4 As shown, a digital storage oscilloscope comprises an oscilloscope body 1, a connecting block 2 is fixed at the bottom end of a side wall of one side of the oscilloscope body 1, a grounding port 101 and a signal input port 102 are respectively arranged at positions of the oscilloscope body 1 located adjacent to the connecting block 2, an angle groove 3 is chiseled at a side of the connecting block 2 away from the oscilloscope body 1, a turntable 4 is arranged inside the angle groove 3, a torsion spring 5 is arranged at a side of the turntable 4 away from the connecting block 2, a Y-shaped plate 6 is twisted and connected at a side of the torsion spring 5 away from the turntable 4, an inner groove 7 is chiseled at the top and bottom ends of the Y-shaped plate 6 away from the torsion spring 5, a fixing column 8 is fixed inside the inner groove 7, a sleeve 9 is slidably connected to the outer wall of the fixing column 8 near one end of the torsion spring 5, a push spring 10 is sleeved on the outer wall of the fixing column 8 away from one end of the sleeve 9, a damping telescopic rod 11 is fixed to the side wall of the sleeve 9 near the oscilloscope body 1, and a jacket 12 is fixed to the telescopic end of the damping telescopic rod 11.
[0022] Specifically, the position of the jacket 12 matches the positions of the ground port 101 and the signal input port 102 , respectively.
[0023] Specifically, the push springs 10 are in contact with one end of the sleeve 9 that is close to the other end. The push springs 10 can push the sleeve 9 forward all the time, so that the jacket 12 can support the end.
[0024] Specifically, tooth block 2 14 is fixed on the front side and the top end of the angle groove 3, and tooth block 13 is fixed on one side of the Y-shaped plate 6 located between the torsion spring 5 and the sleeve 9. The tooth blocks 13 are respectively engaged and connected with tooth blocks 2 14 of matching positions, so that the Y-shaped plate 6 is limited when used horizontally or stored vertically.
[0025] Working principle: When the grounding wire end and the signal input wire end are respectively inserted into the grounding port 101 and the signal input port 102, the two jackets 12 are respectively stuck on the outside of the wire body near the end. Since the circular diameter of the end is larger than the circular diameter of the wire body, the jacket 12 is sleeved on the outside of the wire body, and its end can resist the end. The thrust of the push spring 10 on the sleeve 9 enables the jacket 12 to drive the end to stably resist the grounding port 101 and the signal input port 102, thereby avoiding the situation where the wire connection line end falls off due to small shaking, ensuring the stability during detection and measurement. When it is not needed, the damping telescopic rod 11 is pushed and retracted to the minimum size, and the Y-shaped plate 6 is moved from the horizontal state to the vertical state of the side wall of the oscilloscope body 1 by the combination of the torsion spring 5 and the turntable 4, which plays a role of storage and avoids the convexity when horizontal and affecting the normal storage of the oscilloscope body 1.
[0026] The circuits, electronic components and control modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.
[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
