In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

The testing assembly 3 comprises an ohmic resistance meter 31 and two electrodes 32 electrically connected with two terminals of the ohmic resistance meter 31, the two electrodes 32 are movably arranged on the insulating base 23 to adjust the distance between the two electrodes 32, and one end of each electrode 32 facing the bottom plate 11 protrudes out of the insulating base 23.
With the resistance measuring device for the strip of conductive adhesive in the shield cover according to the embodiment of the present invention, when measuring the resistance of the strip of conductive adhesive 200 on the shield cover 100, first, the shield cover 100 is placed on the bottom plate 11 (see fig. 2). Then, according to the type (material or size) of the conductive adhesive tape 200, a weight 22 with a proper weight is selected, and the interval between the two electrodes 32 on the insulating base 23 is adjusted to ensure that the interval between the two subsequent detection points is kept consistent. Then, the vertical shaft 12 is slid to adjust the vertical shaft 12 and the insulating base 23 to appropriate positions in the Y-axis direction. Then, the first shaft 211 is slid on the lateral shaft 13, and the insulating base 23 is adjusted to a proper position in the X-axis direction, so that the insulating base 23 is moved above the strip of conductive rubber 200 to be measured.
