In this embodiment, except for the screws 1 and the nuts 3, the nuts 3 are metal parts; the other structural parts of the base are made of non-conductive material bakelite. At least two vertical plates 6 are provided, and the vertical plates 6 are provided between the fixing plate 5 and the bottom plate 7, and the columns 2 and the fixing plate 5, and the columns 2 and the bottom plate 7 are all in contact. The perforated plate 4 is provided on the side of the fixing plate 5 away from the bottom plate 7, and the columns 2 are provided between the perforated plate 4 and the fixing plate 5, and the columns 2 and the perforated plate 4, and the columns 2 and the fixing plate 5 are in contact. The perforated plate 4, the columns 2, the fixing plate 5, the vertical plates 6 and the bottom plate 7 are all provided with through holes for the screws 1 to pass through, and the ends of the screws 1 are fixedly connected to the nuts 3.

[0041] Reference Figure 2 and Figure 4 In this embodiment, the orifice plate 4, the fixing plate 5, and the vertical plate 6 are all rectangular panels; the vertical column 2 is a hexagonal copper column. Correspondingly, the screw rods and the vertical column 2 are each provided with four in number and are arranged at the four corners of the orifice plate 4.

[0042] Reference Figures 3 to 5 The fixing plate 5 is provided with a plurality of fixing holes 51 for the spring pins 9 to be inserted and fixed. A convex ring is provided on the side of the spring pin 9 close to the hole plate 4, and the convex ring abuts against the fixing plate 5. Figure 2 and Figure 5 The orifice plate 4 is provided with a receiving groove 41 for receiving the filter 11. The bottom wall of the receiving groove 41 is provided with a plurality of connecting holes 45 for the test head of the spring pin 9 to pass through. The test head of the spring pin 9 is used to abut against the metal contact 111 of the filter 11, and the other end of the spring pin 9 is used to be welded and fixed with the wire.

[0043] The staff puts the filter 11 to be tested into the receiving groove 41 of the orifice plate 4, and sets the side of the filter 11 with the metal contact 111 downward; under the action of gravity of the filter 11, the filter 11 squeezes the spring pin 9 to deform, so that the test head of the spring pin 9 is tightly abutted against the metal contact 111 on the filter 11, so as to quickly complete the power-on test of the filter 11.

[0044] Reference Figure 2 , Figure 4 and Figure 6The receiving groove 41 is a rectangular groove, and avoidance grooves 43 are provided on both sides of the receiving groove 41, so that the staff can place the filter 11 in the receiving groove 41. At the same time, the corners of the receiving groove 41 are provided with notches 42, and there is a gap between the filter 11 and the side wall of the notch 42; thereby reducing the squeezing and friction between the corners of the filter 11 and the side wall of the receiving groove 41, making it easier for the staff to quickly install or remove the filter 11, and also reducing the damage of the test work.

[0045] Reference Figure 2 , the cover plate 8 is hingedly fixed to one side of the orifice plate 4; in this embodiment, the cover plate 8 is hingedly fixed to the orifice plate 4 by a hinge 17.

[0047] After the staff places the filter 11 in the receiving groove 41, the staff closes the cover plate 8 and fixes the buckle body 101 with the buckle hook 102, so that the flexible member 12 presses the filter 11 downward. The filter 11 presses the spring pin 9, so that the spring pin 9 and the metal contact 111 of the filter 11 are closely abutted, thereby achieving stable contact between the filter 11 and the spring pin 9, so as to successfully complete the power-on test.

[0048] Example 2

[0049] The difference between Example 2 and Example 1 is that:

[0050] Reference Figure 7 The number of fixing holes 51 is greater than the number of metal contacts 111 of the filter 11, that is, the number of fixing holes 51 in the fixing plate 5 corresponds to the number of spring pins 9. Therefore, the corresponding spring pins 9 can be placed according to the positions of the metal contacts 111 of different filters 11, so that one tool can adapt to more filter 11 models.
