They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation to the present invention. DETAILED DESCRIPTION

[0016] like Figure 1-4 As shown, the utility model is a circuit online monitor, comprising a body 1, a mounting seat 2, a plug 3 and a limit assembly 4, wherein the mounting seat 2 is connected with a plurality of groups below the body 1, the plug 3 is plugged and arranged below the mounting seat 2, and the limit assembly 4 is sleeved on the outer side of the lower end of the body 1;

[0017] The limit assembly 4 includes a limit connecting frame 5, a limit fixing assembly 6 and a limit adjusting assembly 7;

[0018] The position limiting connecting frame 5 is connected and sleeved on the outer side of the lower end of the body 1;

[0019] The position limiting fixing assembly 6 is connected to the side wall of the position limiting connecting frame 5;

[0020] The limit fixing assembly 6 includes a fixing bolt 8, the limit connecting frame 5 is arranged in a U shape, and an internal threaded hole is connected to the side wall of the limit connecting frame 5, the fixing bolt 8 is threadedly connected to the inside of the internal threaded hole, and one end of the fixing bolt 8 is connected to a fixing plate 9.

[0021] The lower end of the position-limiting connecting frame 5 is connected with a through hole 18, and the position-limiting adjusting components 7 are symmetrically connected to both sides of the through hole 18;

[0022] The limit adjustment assembly 7 includes an adjustment member 10, a limit plate 13, a limit arc member 15 and a return spring 14. The side wall of the limit connecting frame 5 is connected with an adjustment groove 11, and the side wall of the adjustment groove 11 is connected with a limit hole 12. One side of the upper end of the adjustment member 10 passes through the limit hole 12 and is slidably connected to the inside of the adjustment groove 11. The limit plate 13 is connected to one side of the upper end of the adjustment member 10, and the limit arc member 15 is connected to one side of the lower end of the adjustment member 10. The return spring 14 is sleeved on the outside of the adjustment member 10, and the return spring 14 is connected to the inside of the adjustment groove 11.
