Determine needle, positioning column, insulation board, support column, test board, location hole, it is characterised in that: board top surface rear end is vertically and fixedly provided with
The support frame of U-shaped structure, support frame as described above top are equipped with fixed frame, the hold-down devices connection and fixed frame, the lower press fitting
It sets by being threadedly coupled with needle plate, both ends are connect with support frame by guide post on rear side of the needle plate, and the guide post is perpendicularly fixed at
Board top surface, the needle plate plane perpendicular are fixed with insulation fixed pin, are vertically and fixedly provided with two positioning columns on rear side of the needle plate top surface,
The needle plate is arranged right below insulation board, and mainboard is put in insulation plate top surface, and the insulation board is connect by support column with test board,
The test board is set to board top surface.The test board and insulation board have extended vertically through two location holes, the positioning column and positioning
Hole slides up and down connection.
On that basis of the above technical scheme, the positioning column includes spring groove, cross bore, compressed spring, cross column, pressure
Handle, the positioning column bottom are equipped with spring groove, and the positioning column bottom surface is equipped with cross bore, and the compressed spring is set to spring groove
Interior, the cross column is slided up and down with cross bore to be connect, and the cross column bottom end is fixed with round pressure handle.
Compared with prior art, the utility model has the advantage that the positioning column and location hole that the utility model is equipped with,
It avoids needle plate and insulation board position in the horizontal direction shifts, keep insulation fixed pin accurately corresponding with mainboard, positioning column
Cross column and positioning column be internally connected with compressed spring, making to insulate when fixed pin and mainboard contact has certain buffering, protects
Insulation fixed needle and mainboard are not damaged.
