The mechanism of described " fastener longitudinal resistance test device " is: the first cylinder 6 shrinks, and the second cylinder 8 stretches out, and roll-over table 5 is upright, installs rail 3 and fastener.Then, the second cylinder 8 shrinks, and roll-over table 5 playbacks.Frame 7 is moved to test platform 2 by roller 9.First cylinder 6 stretches out, and clip seat 4 is retreated to test platform 2.Pressure head 1 with displacement and force value sensor is pressed in rail 3 one end, and exerts a force rail 3 by test program, records the change in displacement of rail 3 simultaneously.After having tested, the first cylinder 6 shrinks, and clip seat 4 retracts roll-over table 5 slideway.Second cylinder 8 stretches out, and roll-over table 5 is upright, takes off fastener.Second cylinder 8 shrinks, and roll-over table 5 playbacks.
In sum, the fastener longitudinal resistance test device of my invention has the following advantages；
1, clip seat is suitable for multiple fastener, and versatility is good；
2, band displacement and the pressure head of force value sensor, can use the electronic universal tester in laboratory, reduces parts procurement cost, it is achieved a tractor serves several purposes；
3, use pneumatic control, reduce manpower consumption；Regulation air inflow, can control the stretching speed of cylinder, it is to avoid hurt operator；
4, frame band roller, conveniently moving, the used time is not easily removed；
5, machine small volume and less weight, simple in construction, easy care.
