Description

Technical Field

[0001] The invention belongs to the field of woodworking supports, and in particular relates to a pipe bending and bevel cutting saw support. Background Art

[0002] The miter saw stand is an auxiliary stand for woodworking, used to support and fix the miter saw and support wood in order to complete the cutting of wood. In order to facilitate packaging, transportation, carrying and reduce storage space, the stand's tripod structure can be folded. The roller stand used to support wood cannot be folded. Generally, the roller stand is lowered to the lowest position and adjusted to the position closest to the stand table. This method is more suitable for the case where the roller stand is shorter. If the roller stand is higher, the long roller stand column is relatively exposed on the stand table and the folded tripod bracket, and cannot be completely stored; or the roller stand can be directly disassembled and stored separately, which is cumbersome and easy to lose.

[0003] The screw seat is an auxiliary accessory of the miter saw stand, and its function is to fix the miter saw on the table of the miter saw stand. The main body of the commonly used screw seat is the base, and the miter saw is directly fixed on the base, which requires two side-by-side screw seats to support and fix together. Since the width of the base is very narrow, the two screw seats are required to be arranged in appropriate positions in advance during installation, especially the distance between the two must match the width of the miter saw base, otherwise there will be deviations in the installation position and it is not easy to install accurately.
