Description

Corner-changing internal corner plastering device Technical Field The utility model belongs to the field of building construction, and particularly relates to a corner-changing internal corner plastering device. Background The internal corner refers to a concave angle formed by intersecting two adjacent wall surfaces or planes, namely a part with an included angle smaller than 180 degrees. Most of the internal corner plastering tools on the market at present are designed to be ‌ degrees, most of the internal corners except ‌ degrees are disposable plastering tools, wooden or plastic templates are temporarily manufactured according to the internal corner angles, materials are wasted after construction, the comprehensive cost is high, and the construction period can be prolonged when the disposable plastering tools are manufactured. The construction method also directly depends on the experience of workers to manually plaster, and is assisted with ruler calibration, so that the quality is uncontrollable, and angle deviation and line irregularity are easy to occur. Disclosure of Invention The invention aims to overcome the defects of the background technology and provide a variable-angle internal corner plastering device. The invention is realized by the following technical scheme: The utility model provides a change angle reentrant corner plastering device, includes articulated board A and board B that is in the same place, board A medial surface articulates two horizontally connecting rod A from top to bottom symmetry, and board B medial surface articulates two horizontally connecting rod B from top to bottom symmetry, all is equipped with the strip hole on connecting rod A and connecting rod B, and connecting rod B side is equipped with the slot along connecting rod B length direction, and connecting rod A passes the slot, and a threaded rod vertically passes connecting rod A and connecting rod B's strip hole, and the upper end and the lower extreme of threaded rod all are equipped with the nut, cup joints the sleeve on the threaded rod between upper and lower connecting rod B, and sleeve length equals the interval between upper and lower connecting rod B. Preferably, a shaft cylinder A is fixed on the upper and lower sides of one side, far away from the connecting rod A, of the wiping plate A, a shaft cylinder B is fixed in the middle of one side, far away from the connecting rod B, of the wiping plate B, a shaft core is arranged in the shaft cylinder B, and the shaft cylinder A is sleeved on the shaft core and is connected with the shaft core in a rotating mode.
