[0081] In the embodiment, the above structure can effectively avoid the instability of the trimming of the plate material 3 with holes. As shown in Figure 6 Figure 9 As shown in the drawings, under normal circumstances, the three vertical second bearings 516 slide closely against the surface of the plate material 3. However, when the plate material 3 has holes on the surface, the second bearing 516 on the fixed adjusting seat 5151 cannot press the plate material 3. In the present solution, the movable adjusting seat 5152 of the first clamping assembly 51 or the second clamping assembly 52 can move up and down relative to the pressing slide 513. At this time, the second bearings 516 on the two sides of the fixed adjusting seat 5151 and connected with the movable adjusting seat 5152 can support the plate material 3 until the second bearing 516 on the middle fixed adjusting seat 5151 recontacts the plate material 3. In this way, the mechanism can always press the plate material 3, preventing the instability of the trimming of the plate material 3 with holes.

[0082] Further, the first and second close-fitting assemblies 54 and 55 each include a connecting shaft 541 and a first bearing 542.

[0083] The first close-fitting assembly 54 of the embodiment includes a connecting shaft 541 and a first bearing 542. The connecting shaft 541 can include a main connecting shaft 5411 and two auxiliary connecting shafts 5412, which are locked by screws at the front end of the bearing seat 2274. The main and auxiliary connecting shafts 5412 are each embedded with a horizontal first bearing 542. The main and auxiliary connecting shafts 5412 are eccentric shafts, and when the shafts are rotated, the length of the edge of the first bearing 542 protruding relative to the left end edge of the bearing seat 2274 can be finely adjusted. Figure 4 Figure 8 ​​As shown, it is optimal to ensure that the edges of the three transverse first bearings 542 are in the same plane. In this embodiment, in addition to driving the bearing housing 2274 to make reciprocating linear motion, the second driving member 2131 can also provide pressure so that the three transverse first bearings 542 fixed to the front end of the bearing housing 2274 are always in close contact with the plate 3 when they are squeezed by the plate 3.

[0084] like Figure 8 As shown, when the small trimming machine of this scheme is running: the board 3 moves in the direction of the arrow, first passing through the first trimming device 2 and then through the second trimming device 4. The first trimming device 2 or the second trimming device 4 is respectively provided with a corresponding first clamping component 51 and a second clamping component 52. The edges of the three vertically distributed second bearings 516 of the first clamping component 51 and the second clamping component 52 are all on the same plane. The first trimming device 2 or the second trimming device 4 is also provided with a corresponding guide module 227 and a first fastening component 54 and a second fastening component 55 with the same structure. The edges of the three horizontally distributed first bearings 542 fixed on the bearing seat 2274 of the guide module 227 are all on the same plane. The aforementioned vertically distributed second bearings 516 and horizontally distributed first bearings 542 are always in close contact with the plate 3 to accurately position the trimming knife 212, so that the excess edge banding on the plate 3 contacts the two trimming knives 212. The trimming knife 212 of the first trimming device 2 or the second trimming device 4 cuts off the excess part of the edge banding as the first driving component 211 rotates at high speed.
