Embodiment

Referring to figs. 1 through Fig. 5, embodiment of the present utility model is described further.

As shown in Figure 1, a kind of detection fixture, comprise base 0, its base 0 is provided with display 01, several probes 1, control probe 1 to be energized or the pilot pin 3 of through hole on the switch 2 of power-off and fixing pcb board, base 0 is also provided with the clamp device 5 of the device for ejecting 4 and fixing pcb board ejected by pcb board, the utility model fixes pcb board by clamp device 5, serve better fixed effect, simultaneously when clamp device 5 unclamps, pcb board ejects by device for ejecting 4, the utility model reaches the effect of good fixing effect by clamp device 5, facilitated the dismounting of pcb board by device for ejecting 4 simultaneously.

Principle of work of the present utility model is, through hole on pcb board is worn and is emitted through pilot pin 3, now pcb board is clamped by clamp device 5 by operator, and pressed down by device for ejecting 4, open switch 2, switch 2 turning circuit circuit is energized to probe 1 simultaneously, situation about detecting is reflected on display screen by probe 1, then operator loosens clamp device 5, and pcb board ejects by device for ejecting 4, completes material loading, detection and blanking.

As shown in Figure 5, device for ejecting 4 comprises expansion link 41, expansion link 41 comprises the axle 411 and axle sleeve 412 that are mutually slidably connected, expansion link 41 is vertically arranged on base 0, and expansion link 41 being provided with the first elastic component 413, first elastic component 413 that expansion link 41 is resetted is spring, spring can be arranged in expansion link 41, its bottom abuts with base 0, and its top abuts with the interior top of expansion link 41, serves the effect helping expansion link 41 to reset; The another kind of method to set up of same spring is, is located at by spring housing on expansion link 41, and then one end of spring abuts with base 0, and the other end of spring is fixedly connected with the top of expansion link 41, equally also serves the effect that expansion link 41 is resetted.

As shown in Figure 5, one end of expansion link 41 is fixedly connected with base 0, and the other end of expansion link 41 is provided with rubber sleeve 414, and rubber sleeve 414 can prevent the bottom of pcb board from wearing and tearing, and serves the effect of protection product.
