As an embodiment of the present invention, a cavity is provided inside the pressing plate 20; the surface of the pressing plate 20, which is opposite to the output rod 2, and the surface of the rubber anti-skid pad are provided with air outlet holes 23 communicated with the cavity; the interior of the cavity is communicated with the interior of the spring compression tube 18 through a rubber hose; during operation, when the output rod 2 is pressed down, the bottom end of the output rod 2 extrudes the spring compression pipe 18, so that the gas in the spring compression pipe 18 is extruded and enters the cavity through the rubber hose, and finally the gas is blown out from the gas outlet hole 23, so that the dust on the cable and the output rod 2 can be blown off, and the connection effect is better.

The specific working process of the invention is as follows:

when the cable clamping device works, the end part of the cable with the insulation sleeve stripped can be inserted between the bottom ends of the two groups of output rods 2 from the cable inserting port 7, then the top ends of the two groups of output rods 2 are closed, at the moment, the bottom ends of the output rods 2 are also closed, the teeth 24 positioned on the inner wall of the bottom ends of the output rods 2 clamp the end part of the cable, at the moment, the lantern ring 12 slides upwards to fix the relative positions of the two groups of output rods 2, at the moment, the clamping device is pulled outwards to avoid the contact with the output rods 2, then the two groups of output rods 2 can be rotated, so that the end part of the cable is wound inside the arc-shaped clamping groove 25 at the bottom ends of the output rods 2, the output rods 2 can be moved up and down while the output rods 2 are rotated, the cable is uniformly wound at the bottom ends of the output rods 2, when the end part of the cable is completely wound on the output rods 2, the, thereby realize being connected of cable and output rod 2, the installation is swift convenient, and the cable is good with output rod 2's contact nature for current transmission is more stable.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
