Provided is a window corner removal-free protection device. The device comprises a fixing plate, a connecting part, and an anti-collision protection body. The fixing plate and the connecting part arefixed together through a rotating shaft and can rotate freely, a magnet positive electrode is embedded into the fixing plate, a magnet negative electrode is embedded into the corresponding position ofthe connecting part, and fixation is achieved through the principle that the magnet positive electrode and the magnet negative electrode attract each other. At the moment, if free rotation of the fixing plate and the connecting part needs to be achieved by an external force, the fixing plate is installed on the plane surface of the inner side of a window corner, and the anti-collision protectionbody and the connecting part are bonded together through high-viscosity glue to form a whole body (an integrated connecting part). When a window is opened, the anti-collision protection body wraps thewhole foremost end of the window corner. The window corner removal-free protection device can wrap the foremost end of the window corner under the condition of opening the window, a dangerous part iswrapped, and therefore the anti-collision protection effect is achieved. When the window is closed, an integrated structural part can be rotated forcibly, then the magnetic attraction between the connecting part and the fixing plate is separated forcibly, so that the connecting part and the fixing plate are made to rotate freely by the rotating shaft, the whole window corner removal-free protection device is rotated to one side of the inner side plane surface of the window corner, and therefore window closing obstacles cannot be generated between a window frame and the window corner. Therefore, when the window is closed, the dangerous part at the front end of the window corner can be fully wrapped and protected without being taken down, namely being installed once.

一种窗户角免取下防护装置，包括固定板、连接件和防撞护体，其中固定板和连接件通过转轴固定在一起，可以自由的转动，其中固定板中嵌入磁铁正极，连接件相对应的位置中嵌入磁铁负极，利用磁铁正负极相吸的原理实现固定，这时如果要实现固定板和连接件的自由转动需要借助于外力来实现自由转动，固定板安装在窗户角里侧平面表面上，防撞护体和连接件用高粘性胶水粘和在一起而成为一体（一体结件）；开窗时，防撞护体把窗户角最前的一端整个包覆起来，本发明提供的一种窗户角免取下防护装置能够在开窗的情况下包覆住窗户角最前端的部分，把危险的部位包起来，从而起到防撞防护的作用；关窗时，可以用力转动一体结构件，用力分开连接件和固定板上的相互吸引的磁铁吸力通过转动轴使其实现自由转动，把这一种窗户角免取下防护装置整个转动到窗户角里侧平面表面一侧，从而不会在窗框以及窗户角之间产生关窗障碍，这样在关窗时不需要将其取下，也即一次安装，就可以对窗角前端危险部位进行全包围防护。
