[0014] As shown in the figure, the modular splicing test handle comprises a left bracket 1, a right bracket 2, a plug module 3, a plug grip 4, and standard fasteners. The number of plug modules is 2-10 (groups) closely arranged between the left bracket and the right bracket. Each plug module comprises an upper shell 3-1, a lower shell 3-2 (plastic molding) and two test pieces 3-3 and 3-4. The two test pieces, namely the first test piece and the second test piece, are both metal pieces (copper pieces). They are both exposed at the front ends of the upper and lower shells 3-1 and 3-2, and the vertical pieces of the copper pieces are twisted at a right angle to form horizontal pieces (each test piece is a vertical piece that is twisted at a right angle to form a horizontal piece and is a whole). A round hole is provided on the horizontal piece as a test electrode lead-out hole. The flat sheet is inside the upper and lower shells. The upper shell is provided with a test hole connected to the test electrode lead-out hole. The lower shell is provided with a guide plate, which is lined under the exposed vertical (copper) sheet of the first test sheet and the second test sheet; a pin hole is provided on one side of the upper shell or / and the lower shell, and a pin is provided on the other side. The pin hole can be inserted by the pin to relatively fix each plug module and fix it together with the left bracket and the right bracket; the sides of the adjacent plug modules are assembled by the pin holes and pins; the left bracket and the right bracket are on the leftmost and rightmost sides of several matching plug modules, and matching pin holes or pins are provided at the position of the pins or pin holes of the plug modules. The plug handle is installed at the front end of the left bracket and the right bracket. The length of the plug handle is equal to the width of all the plug modules after assembly. The vertical pieces of the two test pieces are standard-sized plug-in metal parts for connecting to the external circuit, fixed between the upper shell 3-1 and the lower shell 3-2.

[0015] The horizontal piece of the second test piece is longer than the horizontal piece of the first test piece in the horizontal direction, and the two test electrode lead holes can be arranged in the horizontal direction, so that each plug module has a smaller and more compact horizontal (width) dimension.

[0016] like Figure 1 As shown in the product functional module composition description, the plug handle 4, the left bracket 1 and the right bracket 2 of the handle are all present; between the left and right brackets is the plug module 4 ( Figure 1 The number can be increased or decreased according to different requirements to meet different application scenarios.
