The surface anti-skid structure of the column body is easier to process and has low cost; the cost of the steel needle material of the cone is lower than that of the column body, the inclined angle is wider than that of the column body, and the success probability of clamping can be increased without adding an anti-skid structure on the surface of the wavy column body.
Further, the steel needles gather inwards, and the inclined angle ranges from 3 degrees to 8 degrees.
Too small an inclined gathering angle can not achieve the gathering and clamping effects, and too large an inclined gathering angle can cause the clamping to be clamped in the hole, so that repeated operation is not facilitated.
Further, the surface of the steel needle is provided with an anti-slip structure.
Further, the anti-skid structure is an annular stripe around the surface of the steel needle.
Further, the anti-skid structure is a hemispherical protrusion which is uniformly distributed on the surface of the steel needle.
Further, the anti-skid structure is staggered stripes surrounding the surface of the steel needle.
The above anti-skid structures are freely matched according to the structure of the steel needle, the processing difficulty, the cost control and other factors.
Further, an electromagnet wire channel is arranged on the cylinder.
Advantageous effects
The invention has simple structure and convenient and reliable processing. The steel needle bundle freely enters and exits in the through hole, when encountering the surface of a back clamp object with holes, the steel needle bundle freely falls into the holes according to the shape of the object surface and can fall into different holes according to the different holes on the surface, after the steel needle bundle is electrified, the steel needles in the steel needle bundle are gathered together, the current state is fixed, and the object is clamped; under the condition that the punching position and the size of the diaphragm are not considered, the model can be fixed in a freely changeable mode, so that the mechanical automatic production machine is convenient for grabbing and fixing the mechanical arm, and the production efficiency is improved.
