[0008] The effect achieved by the above components is: when the upper and lower splints clamp the floral wire, the extrusion block squeezes the floral wire into the square groove and clamps it, thereby increasing the contact area between the block and the floral wire and clamping the floral wire as tightly as possible.
[0009] Preferably, a guide rail is fixedly connected between the isolation frames, and the upper clamping plate and the lower clamping plate slide vertically along the guide rail between the two isolation frames.

[0015] Preferably, a slope is provided on one side of the limit block.
[0016] The effect achieved by the above components is: when using a hard wire, the hard wire can be passed through the wire hole along the inclined surface of the limit block. At this time, the hard wire squeezes the limit block to squeeze the spring so that the hard wire can pass through the wire hole, and then the hard wire can be quickly connected.
[0017] Compared with the prior art, the advantages and positive effects of the present invention are:
[0018] In the utility model, the flex wire is wrapped around the surface of the bolt, and by tightening the bolt, the bolt drives the upper clamping plate close to the lower clamping plate, and then the flex wire is clamped and fixed between the upper clamping plate and the lower clamping plate. Then, the flex wire is electrically connected to the digital display meter with the help of the bolt, and the stripped end of the flex wire insulation layer passes through the buckle arm. When the upper clamping plate squeezes the lower clamping plate, the buckle arm completely squeezes and clamps the flex wire, and the concave structure presses on the surface of the flex wire to further fix the flex wire, thereby reducing the possibility of the flex wire loosening as much as possible.

The stabilizing mechanism 3 includes a plurality of isolation frames 31, wherein the plurality of isolation frames 31 are provided on the surface of the terminal frame 2 to separate the terminal frame 2 into a plurality of areas, and an upper clamping plate 33 and a lower clamping plate 312 are provided in each area, wherein a bolt 34 passes through the upper clamping plate 33 and the lower clamping plate 312 and is threadedly inserted into a screw hole 35 on the surface of the terminal frame 2, and a surface of the lower clamping plate 312 is evenly provided with square grooves 37, wherein a buckle arm 38 is fixedly connected in any square groove 37, wherein a downwardly bent concave 39 is provided on the surface of the buckle arm 38, wherein the digital display meter 1 can be a digital display for voltage detection. The voltage detection digital display meter is a conventional product currently sold on the market, so the specific wiring principle will not be elaborated here. When wiring is required, the insulation layer of the flexible wire is stripped off, and then the flexible wire is wrapped around the surface of the bolt 34. By tightening the bolt 34, the bolt 34 drives the upper clamping plate 33 close to the lower clamping plate 312, and then the flexible wire is clamped between the upper clamping plate 33 and the lower clamping plate 312 and fixed. Then, the flexible wire is electrically connected to the digital display meter 1 with the help of the bolt 34. The stripped end of the flexible wire insulation layer passes through the buckle arm 38. When the upper clamping plate 33 squeezes the lower clamping plate 312, the buckle arm 38 completely squeezes and clamps the flexible wire, and the concave 39 structure presses on the surface of the flexible wire to further fix the flexible wire, thereby reducing the loosening of the flexible wire as much as possible. When the upper and lower clamping plates 33 are in the closed position, the clamping plates 331 are in the closed position, and the upper and lower clamping plates 331 are in the closed position, so the clamping plates 331 are in the closed position. To be stuck in the limiting hole 36 and thus prevent rotation between the lower clamping plates 312, a quick-install component 4 is provided on the surface of the bolt 34, and the cable is inserted in the quick-install component 4 for electrical assembly. The quick-install component 4 includes a wire hole 41 horizontally passing through the bolt 34, and an assembly groove 42 connected to the wire hole 41 is provided inside the bolt 34. The internal sliding connection of the assembly groove 42 is connected to the limiting block 44, and a spring 43 is fixedly connected between the limiting block 44 and the assembly groove 42.

At this time, the hard wire squeezes the limiting block 44 so that it squeezes the spring 43, thereby allowing the hard wire to pass through the wire hole 41, and then the hard wire can be quickly connected.
[0027] Working principle, wherein the digital display meter 1 can be a digital display meter for voltage detection (since the voltage detection digital display meter is a conventional product sold on the market, the specific wiring principle will not be excessively elaborated here). When wiring is required, the insulation layer of the flexible wire is stripped off, and then the flexible wire is wrapped around the surface of the bolt 34. By tightening the bolt 34, the bolt 34 drives the upper clamping plate 33 close to the lower clamping plate 312, and then the flexible wire is clamped between the upper clamping plate 33 and the lower clamping plate 312 and fixed. Then, the flexible wire is electrically connected to the digital display meter 1 with the help of the bolt 34. The stripped end of the insulation layer of the flexible wire passes through the buckle arm 38. When the upper clamping plate 33 squeezes the lower clamping plate 312, the buckle arm 38 completely squeezes and clamps the flexible wire, wherein the concave 39 structure presses The surface of the floral wire is further fixed to minimize the loosening of the floral wire. When the upper clamp 33 and the lower clamp 312 clamp the floral wire, the extrusion block 311 squeezes the floral wire into the square groove 37 to clamp it, thereby increasing the contact area between the floral wire and the extrusion block 311 to clamp the floral wire as much as possible. The guide rail 32 limits the movement direction between the upper clamp 33 and the lower clamp 312. The protrusion can be stuck in the limiting hole 36 to prevent rotation between the lower clamp 312. When using a hard wire, the hard wire can be passed through the wire hole 41 along the inclined surface of the limiting block 44. At this time, the hard wire squeezes the limiting block 44 to squeeze the spring 43, so that the hard wire can pass through the wire hole 41, and then the hard wire can be quickly connected.
