Sliding block is set on pedestal and can be slided relative to pedestal；
Two test probes, are set on sliding block, and the spacing of two test probes is the spacing of product two sides termination electrode,
The corresponding position of the product placing groove is provided with the through-hole stretched into for test probe in product placing groove；
Driving mechanism, for drive sliding block towards one Slideslip of product placing groove and make test probe pass through through-hole and with
Product is engaged.
When the utility model is used, product placement plate is fixed on pedestal, surface-mount type fuse is then positioned over production
In product placing groove, sliding block sliding is then driven by driving mechanism, since test probe is set on sliding block, tests probe
Through-hole will be slid through, and will be extended in product placing groove, will be engaged respectively with surface-mount type fuse two sides termination electrode, this
It is located at product placing groove both sides by two groups of mechanism for testing in utility model, when four test probes and surface-mount type fuse contact
When, fixed function can also be played to surface-mount type fuse so that surface-mount type fuse position is fixed, and will not be moved, because
This, which improves product resistance value, must measure precision.
In the utility model there are many structures of driving mechanism, preferably, the driving mechanism includes being fixed with sliding block
The push rod of connection.
Preferably, the test group further includes Spring screws, the Spring screws are located at sliding block and product placement plate is straight
It connects, one end of the Spring screws is fixedly connected with a slide block, and the other end is connected on the side wall of product placement plate.The utility model
Middle Spring screws can play reset response, to ensure the accuracy measured.
It is connect with measuring instrument for the ease of test probe, preferably, being offered on the pedestal for test probe
The notch that connecting line passes through.
For the ease of the trial product to be measured to different model size, preferably, the product placement plate is solid by bolt
Due on pedestal.Product placement plate is detachably connected in the utility model, therefore can need replacing different size according to measurement
Product placement plate, to measure the trial product to be measured of different model size.
Compared with prior art, the beneficial effects of the utility model are embodied in：
It is located at product placing groove both sides by two groups of mechanism for testing in the utility model, when four test probes and surface-mount type
When fuse contact, fixed function can also be played to surface-mount type fuse so that surface-mount type fuse position is fixed, Bu Huifa
Movement is given birth to, therefore improve product resistance value to measure precision.
Description of the drawings
