Background

The circuit board can be called as a printed circuit board or a printed circuit board, and the FPC circuit board is also called as a flexible printed circuit board which is made of polyimide or polyester film as a base material and has high reliability and excellent flexibility. The high-density light-weight LED lamp has the characteristics of high wiring density, light weight, thin thickness and good bending property. And the birth and development of the FPC and the PCB of the rigid-flexible Printed Circuit Board (PCB) urge the generation of a new product of the rigid-flexible printed circuit board (FPC). Therefore, the rigid-flex circuit board is a circuit board with FPC (flexible printed circuit) characteristics and PCB (printed circuit board) characteristics, which is formed by combining a flexible circuit board and a rigid circuit board according to relevant process requirements through processes such as pressing and the like.

But at present most anchor clamps use so conveniently, can't adjust holistic size, can't work to the circuit board of equidimension not. An adjustable clamp for circuit board soldering, as disclosed in CN207083303U, can solve the above problems, but has the following disadvantages, such as: back splint thickness is limited, sets up the guide rail groove in that the lateral wall is inside, installs tensile pole and the elastic component that resets at the guide rail inslot simultaneously and all comparatively troublesome and operate inconveniently, is unfavorable for the using widely of equipment to it is rotatory in order to drive spacing buckle how to guarantee that it can not take place to rotate when tensile pole when the guide rail inslot displacement, makes the opening in the spacing buckle not take place crooked and can just block the problem that the circuit board border also need to be solved urgently.
