Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building, and particularly relates to a self-adjusting dual-purpose smearing device for internal and external corners. BACKGROUND

[0002] An internal corner refers to a concave corner of a wall, such as the angle between a top surface and surrounding walls, and an external corner refers to a convex corner of a wall, such as the angle formed by two walls at a turning of a walkway. However, most existing internal and external corners are 90° corners, and the internal and external corner smearing devices on the market can smear internal and external corners, but when the internal and external corners are some special angles, such as angles greater than 90° or less than 90°, the existing smearing devices on the market do not have the function of synchronously smearing internal and external corners. In a construction site, the smearing operation of internal and external corners mostly needs to be performed on site according to the angles of internal and external corners. Although the smearing device for internal and external corners is made on site, the degree of adaptation is high, but the disadvantage is that the smearing device can only be adapted to smearing of one type of angle. With the diversification of building shapes, the smearing angles of internal and external corners at different positions of the same building certainly differ. Once the smearing device is adapted to smearing of a single angle, the smearing device will cause some unevenness during smearing. Even if the smearing operation is manually performed twice, the appearance will be affected. In addition, the smearing strength of the smearing device made on site is difficult to control, and there is no corresponding measure to actively adjust and enhance the smearing strength. Sometimes, multiple smearing devices for internal and external corners need to be made to complete the smearing of an internal and external corner, resulting in waste of materials. SUMMARY
