[0013] Figure 2 It is a schematic diagram of the structure of an embodiment of the utility model. DETAILED DESCRIPTION

[0014] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0015] A kind of Figure 1-2 The key bottom plate attachment tool shown in the figure includes a base 1, and the base 1 has a first station and a second station arranged in parallel, wherein the first station is used to attach the center column to the film circuit board, and the second station is used to attach the film circuit board to the base. The first station includes a center positioning hole 2 set on the base, and the center column is pre-positioned in the center positioning hole 2. The left side of the center positioning hole 2 has a first positioning block 3, and the right side of the center positioning hole 2 has a second positioning block 4. The inner side of the first positioning block 3 has a first positioning portion 31, and the inner side of the second positioning block 4 has a second positioning portion 41. The structures of the first positioning portion 31 and the second positioning portion 41 are adapted to the shape of the notch on the film circuit board.

[0016] In order to prevent the film-type circuit board from deforming during the attachment process, the center positioning hole 2 of this embodiment has a first groove 5 in front, and a first positioning pin assembly 6 is provided on the bottom surface of the first groove 5. The first positioning pin assembly 6 includes two cylindrical pins, wherein the cylindrical pin on the left side has a smaller diameter than the cylindrical pin on the right side, and is used to locate the two holes in the front of the film-type circuit board. The center positioning hole 2 has a second groove 7 at the rear, and a second positioning pin assembly 8 is provided on the bottom surface of the second groove 7.
