In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit or scope of the utility model, which is therefore not limited to the specific embodiments disclosed below.

It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

An ejector mechanism is used for being mounted on a mounting body 10 so as to push away a first object which is magnetically connected with the mounting body 10, thereby facilitating the detachment of the mounting body 10 from the first object. The mounting body 10 is a frame, the first object is a display module, the frame is magnetically connected with the display module, and the pushing mechanism can push the display module away from the frame.

The pushing mechanism comprises a push rod 1 and a cam handle 2, wherein the push rod 1 is in a strip shape, the installation body 10 is provided with a first installation hole 11, and the push rod 1 is arranged in the first installation hole 11; the cam handle 2 is hinged with the installation body 10 or the pushing mechanism further comprises an installation piece 3, and the installation piece 3 is fixedly connected with the installation body 10; the cam handle 2 is hinged with the mounting member 3. The cam handle 2 is in abutting connection with the push rod 1; when the cam handle 2 is rotated, the cam handle 2 can push the push rod 1 to move in a direction approaching the first object so as to push the first object away from the mounting body 10, thereby conveniently and laborsaving separating the mounting body 10 from the first object.

In some embodiments, the cam handle 2 is hinged to the mounting body 10 via a pin. The mounting piece 3 is provided with a second mounting hole 301, the second mounting hole 301 is communicated with the first mounting hole 11, and the push rod 1 extends into the mounting piece 3 through the second mounting hole 301 to be in butt joint with the cam handle 2. The mounting piece 3 is provided with a third mounting hole, the screw 4 penetrates through the third mounting hole and is fixedly connected with the mounting body, and the head of the screw 4 is abutted to the mounting piece 3. The cam handle 2 is hinged with the mounting piece 3, and the mounting piece 3 is fixedly connected with the mounting body 10 through the screw 4, so that the cam handle 2 is conveniently mounted on the mounting body 10.

In some embodiments, in order to enable the push rod 1 to automatically retract into the first mounting hole 11 after the cam handle 2 rotates back, the push-out mechanism further includes an elastic member, one end of the elastic member abuts against the push rod 1, and the other end of the elastic member abuts against the mounting body 10. When the cam handle 2 is rotated, the cam handle 2 pushes the push rod 1 out of the first mounting hole 11, the elastic member is compressed, and when the cam handle 2 is rotated back, the elastic member is reset to be extended, and the elastic member pushes the push rod 1 to retract into the first mounting hole 11.
