Detailed Description
Referring to fig. 1 to 3, a specific structure of a preferred embodiment of the present invention is shown, which includes a bottom plate 10 and a bump 20 integrally extending from an upper surface of the bottom plate 10.
The top surface of the base plate 10 is provided with a projection 20 on the inner side thereof for mounting an extrusion clip or the like. The upper and lower surfaces of the bottom plate 10 are provided with an avoiding groove 11 in the center, the upper end opening of the avoiding groove 11 is covered by the convex block 20, and the avoiding groove 11 is circular and is convenient to process. And four corners of the bottom plate 10 are all provided with screw holes 12, and one of the screw holes 12 is a countersunk head 121, so that the extrusion clamp is prevented from moving on the extrusion seat to generate interference, and screws at the countersunk head 121 are required to be countersunk.
This lug 20 includes that main part 21, shaping are connected in the first reinforcing plate 22 of main part one side and the shaping is connected in the second reinforcing plate 23 of main part opposite side, and when processing drilling to main part 21, first reinforcing plate 22 and the effective power that disperses main part 21 and receive of second reinforcing plate 23 avoid main part 21 atress to concentrate and fracture. The thickness of the main body 21 is respectively larger than the thickness of the first reinforcing plate 22 and the second reinforcing plate 23, so that the materials for the two reinforcing plates are reduced, and the cost is saved. A through hole 211 for the consumable to pass through penetrates through the inner side surface and the outer side surface of the main body 21, and the through hole 211 comprises a first through hole 201, a second through hole 202 and a thread hole 203 for mounting a pneumatic connector, which are sequentially communicated from inside to outside; the diameters of the first through hole 201, the second through hole 202 and the thread hole 203 are sequentially increased, and the thread hole 203 is used for installing an eighth-made pneumatic connector.
