[0020] The test head 5 is installed on the fixture base plate 1, and the base 9 is slidably arranged on the fixture base plate 1. The top of the base 9 is detachably connected to the upper cover 23, and the upper cover 23 is slidably connected to the pressure needle 10. The bottom of the pressure needle 10 can slide through the base 9. The test head 5 is located below the pressure needle 10. The handle 14 is rotatably connected to the base 9, and one end of the handle 14 is movably connected to the pressure needle 10 so as to push the pressure needle 10 up and down to tighten or loosen the test piece on the test head 5.

[0021] The test head 5 is a prior art test head of a high frequency impedance tester, which is used to prevent the tested object, i.e., the bottom electrode. By rotating the handle 14, the pressing needle 10 can be moved up and down, so that the pressing needle 10 can be pressed or separated from the test head 5, and then the pressing needle 10 can be moved away from or close to the test head 5 by sliding the base 9, so that the tested object can be taken and placed.

[0022] Furthermore, a connecting plate 24 is detachably connected to the bottom of the base 9 , and the connecting plate 24 is slidably mounted on the fixture bottom plate 1 via a guide rail 2 .

[0023] A plurality of groups of holes are arranged on the fixture bottom plate 1, which are respectively used to fix the test head 5, the guide rail 2, and the connecting plate 24. Long holes are arranged at both ends of the connecting plate 24, and captive screws 8 are arranged in the long holes. The captive screws 8 can pass through the long holes without falling off. At the same time, the connecting plate 4 is provided with holes and grooves. The holes are used to fix with the base 9. The size of the groove matches the guide rail 2. After matching, it can slide back and forth on the guide rail.

[0024] Furthermore, a concave cavity is formed in the upper cover 23, and a spring 22 is sleeved on the upper end of the pressure needle 10. The spring 22 is located in the concave cavity, and the top of the pressure needle 10 passes through the upper cover 23. The spring 22 is used to push the pressure needle 10 downward to press the test piece. When the spring 22 is in the initial state, the pressure needle 10 presses the test piece; when the handle 14 is pressed downward, the pressure needle 10 moves upward to squeeze the spring 22 and detaches from the test head 5.

[0025] Furthermore, an adjusting nut 21 is sleeved in the concave cavity and on the pressing needle 10, and the bottom of the second spring 22 abuts against the adjusting nut 21. The adjusting nut 21 can adjust the tightness of the second spring 22.

[0026] Furthermore, a waist-shaped hole is provided at the end of the handle 14, a fixing sleeve 16 is sleeved on the pressing needle 10, a rotating shaft is provided on the side of the fixing sleeve 16, and the rotating shaft is movably arranged in the waist-shaped hole.

[0027] Furthermore, a hollow part is provided in the base 9, and the middle end of the handle 14 is rotatably installed in the hollow part. A second fixing pin 19 is detachably connected in the hollow part, and the second fixing pin 19 is located between the upper and lower maximum strokes of the handle 14 to constrain the movement of the handle 14. The second fixing pin 19 can be detachably connected with the base 9 by plugging, threading, or screwing; when the handle 14 is at the maximum stroke of upward rotation, the pressure needle 10 presses the measured object, and the second fixing pin 19 is inserted to abut the lower end of the handle 14; when the handle 14 is at the maximum stroke of downward pressing, the pressure needle 10 is separated from the measured object, and the second fixing pin 19 is inserted to abut the upper end of the handle 14; the second fixing pin 19 realizes the function of locking the handle 14.

[0028] The base 9 is provided with multiple groups of holes for connection with the upper cover 23, and also meets the installation of the pressure needle 10, the connection plate 24, the handle 14, the fixing pin 17, and the fixing pin 2 149. The upper cover 23 is provided with multiple groups of holes for connection with the base 9, one of which is provided with a D-shape, through which the pressure needle 10 can pass, and restricts the rotation of the pressure needle 10. The fixing sleeve 16 is provided with multiple groups of holes, through which the pressure needle 10 can pass, can be used for fixing with the screw 5 15, can be used for installing the cushion block 18, and is provided with a rotating shaft at the same time.

[0029] The installation and workflow of this utility model are as follows:

[0030] When in use, screw 1 3 fixes guide rail 2 to fixture bottom plate 1, and guide rail 2 is provided with a positioning boss to fit on fixture bottom plate 1 to limit the rotation of guide rail 2. Screw 3 6 fixes test head 5 to fixture bottom plate 1. Fixture bottom plate 1, guide rail 2, screw 1 3, test head 5, screw 3 6 form a fixture bottom plate assembly.

[0031] The captive screw 8 is screwed into the long hole of the connecting plate 24, and the connecting plate 24 is fixed to the base 9 with the screw 24. The pressure needle 10 is inserted into the fixing sleeve 16, and then the cushion block 18 is installed from the side, and the pressure needle 10, the cushion block 18, and the fixing sleeve 16 are locked with the screw 5 15. The waist-shaped hole at the front end of the handle 14 is put on the rotating shaft of the fixing sleeve 16, and then the whole is installed on the base 9. When installing, the pressure needle 10 passes through the corresponding D-shaped hole of the base 9; the fixing pin 17 passes through the base 9 and the handle 14, and the fixing pin screw 11 is screwed into the fixing pin 17 to fix it. The handle 14 can rotate along the fixing pin 17. When locking, the spring 120 is put on the fixing pin 2 19, and then passes through the corresponding hole of the base 9, and is screwed into the fixing pin 2 19 with the fixing pin screw 2 13 to fix it, and the rubber cover 12 is pressed into the base 9. The adjusting nut 21 is screwed onto the fixing sleeve 16, and the spring 22 is put on. Install the upper cover 23 on the base 9 from top to bottom, and lock the upper cover 23 to the base 9 with screws 297. The upper cover 23 needs to be installed so that the pressure needle 10 passes through the corresponding D-shaped hole on the upper cover 23. After the above installation is completed, a clamping device is formed.

[0032] Install the clamping device on the fixture base plate assembly, align the guide rail 2 on the fixture base plate assembly into the groove of the connecting plate 24 on the clamping device, and tighten it with the captive screws 8. Loosening the captive screws 8 at both ends allows the clamping device to slide back and forth on the guide rail so that the pressure pin is aligned with the workpiece under test. Pushing one end of the handle 14 downward can cause the handle to rotate around the fixing pin 17, and the other end of the handle 14 drives the fixing sleeve 16 and the pressure pin 10 to move upward. The pressure pin 10 can be moved upward to release the workpiece under test, thereby releasing the clamping function. Under the action of the spring 22, the pressure pin 10 can move downward to clamp the workpiece under test, and the compression amount of the spring 22 can be adjusted by adjusting the adjusting nut 21 to adjust the clamping force of the pressure pin 10. Thereby, flexible adjustment can be achieved according to the different heights and clamping force requirements of the workpiece under test.

[0033] When the clamping state is released, the handle 14 can be locked by installing the second fixing pin 19. It is convenient to place and replace the measured object and adjust the position. The lock can be released by removing the second fixing pin 19, and the handle 14 can be loosened to clamp the measured object.

[0034] The clamping device of the base electrode device is convenient and reliable, easy to realize the compression and decompression action, and simple to operate. When a large number of tests are carried out, the test can be completed quickly, greatly improving the efficiency.

[0035] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention.
