Edge is respectively and fixedly provided with fixed column, and is connect with telescopic rod by spring on the outside of fixed column, telescopic rod surface both sides
It is symmetrically arranged with limiting plate, the telescopic rod appearance wall is fixed with draw ring, and the telescopic rod upper surface is fixed with grip block, described
Grip block inner surface is provided with insulation spacer, and the grip block internal whorl is connected with holding pin, and holding pin lower surface is fixed
There are insulating press boards.
As further describing for above-mentioned technical proposal：
There are four the grip block is installed altogether, and four grip blocks are symmetrical between any two.
As further describing for above-mentioned technical proposal：
The cross section of the draw ring is semicircular arc structure.
As further describing for above-mentioned technical proposal：
The junction of the telescopic rod and limiting plate is provided with the ball for rolling friction.
As further describing for above-mentioned technical proposal：

As further describing for above-mentioned technical proposal：
The maximum tension amplitude of the spring is 3cm.
In the utility model, first by four grip blocks of setting, circuit board can be clamped from four direction
It is fixed, the stability of circuit board clamping is ensure that, while coordinating sucker, by sucker interior suction at vacuum state, to maximized
The phenomenon that ensure that the clamping stability of circuit board, will not shaking can be to telescopic rod secondly by the limiting plate of setting
Telescopic process play the role of position limitation protection, and ball can reduce the frictional resistance between telescopic rod and limiting plate, be convenient for
The telescopic moving of telescopic rod operates, and the use abrasion of fixed clamp is reduced, finally by the insulating press boards and felt pad of setting
On the one hand piece can play the circuit board in grip block the clamping effect of subtle spacing, on the other hand the structure of insulation is also kept away
Exempt from circuit board in test there is a phenomenon where leaking electricity, improves the safety in utilization of fixed clamp.
