[0009] Further, the spring specifically has a plurality of springs, and the plurality of springs are uniformly distributed on two sides of the follow-up positioning seat.

[0010] Further, the blocking roller and the positioning roller specifically are rubber-coated wheels.

[0011] The beneficial effects of the utility model are that: the linkage design of the first positioning material blocking assembly and the second positioning material blocking assembly and the elastic positioning assembly can adapt to the positioning and clamping of router housings of different sizes.

[0012] The blocking roller and the positioning roller adopt the design of rubber-coated wheels, effectively reduce the risk of surface scratches or indentation marks generated during positioning and clamping, and can adjust the height of the placed router, avoiding deformation of the open part caused by clamping.
