This creation is about a pressure measuring mechanism, and especially about a pressure measuring mechanism for impedance measurement.

The traditional impedance measurement mechanism presses the device to be tested on the stage through the pressing member, so that the pins of the device to be tested can closely contact the electrode contacts of the stage, so as to provide the back-end system for testing. In addition, the impedance measurement mechanism can perform individual tests for a variety of different types of components under test. Whenever the impedance measuring mechanism is changed to test a different type of component to be tested, in order to allow the pressing member to effectively press the component to be measured of this different type, the user needs to change the configuration orientation of the stage so that the component to be measured moves. to the effective position below the lower pressing piece.

However, since the stage of the impedance measurement mechanism contains many complex and stacked components, in order to change the arrangement orientation of the stage, the user must take out these components in the stage in sequence, then rotate the orientation in sequence, and then follow the It is not only time-consuming and laborious, but also may cause damage to the component to be tested due to wrong installation.

The second slot 254 is formed at the front end 251 of the push member 250 for passing through one end of the lower pressing rod 280 opposite to the accommodating groove 101 . The pressing rod 280 can move along the second slot 254 to adjust the inclination of the pressing rod 280 . The locking member 260 is fixed on one end of the lower pressing rod 280 opposite to the accommodating groove 101 , and restricts the lower pressing rod 280 to the pushing member 250 . The second end 242 of the bracket 240 has an elongated slot 243 . The spring element 270 is located in the elongated slot 243 , is sleeved on the lower pressing rod 280 , and abuts against the lower pressing rod 280 and the stopper 281 in the elongated slot 243 . The long axis direction (eg, Z axis) of the elongated slot 243 is orthogonal to the long axis direction (eg, X axis) of the first slot 220 and the long axis direction (eg, Y axis) of the second slot 254 , respectively.

In this way, when a user pushes the rear end 252 of the push member 250 toward the bracket 240, so that the front end 251 of the push member 250 pulls up the lower pressure rod 280, and the lower pressure rod 280 is pulled away from the accommodating slot 101, the spring element 270 is compressed and stores a restoring force. On the contrary, when the user releases the rear end 252 of the pushing member 250 , the restoring force of the spring element 270 pushes the pressing rod 280 back into the accommodating slot 101 .
