Adjustable artware fastening device

Abstract

The invention discloses an adjustable handicraft fastening device, which comprises a working slot, and two oppositely arranged fixing plates are arranged in the working slot, and the fixing plates include a vertically arranged main board and side plates vertically connected to two ends of the main board , the side plate is slidingly connected with the inner side wall of the working tank, and the side surface of the main board away from the side plate is connected with a driving rod; the opposite wall of the two fixed plates is provided with a soft bag, and the soft bag is filled with polyurethane particles. In the fastening device of the present invention, by setting the soft bag, the shape of the soft bag can be deformed when it is in contact with the surface of the handicraft, and the soft bag is filled with polyurethane particles, so the soft bag can be squeezed and deformed arbitrarily and is in contact with the surface of the handicraft. The complete fit can not only prevent the surface of the handicraft from being worn, but also the handicraft is evenly stressed, and will not cause stress concentration in certain parts during the fixing process; it can be flexibly adjusted according to the size of the handicraft.

Description

technical field [0001] The invention relates to a fixing device, in particular to an adjustable handicraft fastening device. Background technique [0002] Handicraft is a handicraft product. It is a product of artistic value made by processing raw materials or semi-finished products by hand or machine. Handicrafts come from life, but they create a value higher than life.

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the size of the object that can be fixed by the existing processing and fixing device is fixed, and at the same time, the surface of the object is not a smooth plane or arc surface, and there will be recessed or protruding parts, so When the object is fixed, the contact surface between the fixing device and the surface of the object is a protruding part. Not only is the area small, the stability of the fixation is poor, and the fastening force is too large to cause damage to the object. Adjustable handicraft fastening device, by setting the soft bag, the shape of the soft bag can be deformed when it is in contact with the surface of the handicraft. The complete fit can not only prevent the surface of the handicraft from being worn, but also the force of the handicraft is uniform, and will not cause stress concentration in some parts during the fixing process; at the same time, it can be flexibly adjusted according to the size of the handicraft, suitable for various fixation of objects
