Be provided with the tool thimble pressing plate of tool thimble, it is connected with described quick clip mechanism by a switching pressing plate, and described quick clip mechanism drives described tool thimble pressing plate to move up and down by described switching pressing plate;
Be arranged on the pcb board seat on described base plate, described pcb board seat is provided with the groove for placing PCB.
Adopt quick clip mechanism as the driving mechanism of PCB test tool in the utility model, pull quick clip mechanism namely by the stretching out and get back and drive tool thimble pressing plate to pump of depression bar of quick clip mechanism, thus the contact completing test thimble and PCB test point be separated, convenient to operation, quick clip gear grips power is large and positioning and bounce-back can not occur.When pulling quick clip mechanism, the acting force of quick clip mechanism is first applied on switching pressing plate, remake and use on tool thimble pressing plate, a cushion is defined like this between tool thimble pressing plate and quick clip mechanism, the acting force that presses down due to quick clip mechanism can be avoided to a certain extent excessive, thus the tool thimble pressing plate caused drive tool thimble to contact with the undue of PCB test point.Further, pcb board seat arranges groove, when testing, PCB being placed in the groove on pcb board seat, just can completing the accurate location of PCB.
Preferably, described tool thimble pressing plate is connected with described switching pressing plate by connecting column.
When pulling quick clip mechanism, the acting force of quick clip mechanism is first applied on switching pressing plate, then is applied on tool thimble pressing plate by connecting column, better for the buffering effect between quick clip mechanism and tool thimble pressing plate.
Preferably, described connecting column adopts socket head cap screw.
The strength of joint of socket head cap screw is comparatively large, guarantees that the connection of card extender and tool thimble pressing plate is firm.
Preferably, between described pcb board seat and described tool thimble pressing plate, be provided with guidepost, described guidepost is fixed on described base plate, and described tool thimble pressing plate is provided with the pilot hole passed for described guidepost.
The setting of guidepost and pilot hole makes tool thimble pressing plate can only move along the direction of guidepost, limits the movement locus of tool thimble pressing plate, thus ensure that tool thimble contacts with PCB test point along specific track.
Preferably, between described riser and described base plate, gusset plate is provided with.
The setting of gusset plate makes riser and floor form the stronger three-legged structure of a stability.
Preferably, bottom described base plate, backing plate is provided with.
The setting of backing plate enhances the structural stability of support.
The utility model structure is simple, simple operation.In use, only need PCB to be placed in the groove on pcb board seat, then pull quick clip mechanism and just can complete contacting of test thimble and PCB test point, and test thimble and can contact with PCB test point along the movement locus determined.Under ensureing that PCB tests the prerequisite of effect, greatly improve testing efficiency.
