After connection, they can be moved horizontally on the surface of the placement groove 103. When positioning is required, the fixing screws 204 and the limiting screw holes 203 are tightened by screws to fix it on the surface of the limiting slide groove 105. The setting of the push plate 205 facilitates better movement of the limiting strip 201.

The positioning base structure 1 is mainly used to place the positioning copper frame 4, while the baffle structure 2 and the limiting clamp structure 3 are mainly used to enclose the positioning copper frame 4 to prevent displacement and thus production. The base plate 101 is installed at the processing position through the fixing holes 102. The positioning copper frame 4 can be mated to the surface of the placement groove 103. The side sliding groove 104 and the limiting sliding groove 105 are mainly used for the connection and sliding of the baffle structure 2. The sliders 202 at both ends of the limiting strip 201 are mated with the side sliding groove 104. After mating, they can...
