The fixing frame 3 has a pushed portion 32, and the pushed portion 32 is specifically formed at one end of the fixing frame 3. The fixing frame 3 can also be provided with a plurality of fisheye grooves 33 for limiting and guiding.

The movable frame 4 is movably connected to the fixed frame 3, so that the movable frame 4 can move relative to the fixed frame 3. The present invention is not limited to the manner in which the movable frame 4 moves relative to the fixed frame 3, and may be moved, rotated, rolled, or slid, and the movable frame 4 in the present embodiment will be described by taking the example of slidably sliding on the fixed frame 3. It should be noted that the sliding direction D (see fig. 6) in which the movable frame 4 slides relative to the fixed frame 3 is parallel to the length direction of the connector C (or parallel to the long side (not labeled with a reference numeral) of the connector C), and in other embodiments not shown in the drawings, may also be parallel to the width direction of the connector C or parallel to other directions except the length direction and the width direction.

The movable frame 4 may have a tapered edge 421 itself, or may have a tapered edge 421 through an additional arrangement, and the embodiment is described as follows: the movable frame 4 comprises a frame body 41 and a block 42, wherein the block 42 is fixed on the frame body 41 and has a tapered edge 421. Wherein, the frame body 41 can also be a beam-shaped frame body, and the frame body 41 can be slidably connected to the fixing frame 3 and is parallel to the fixing frame 3.

The passive frame 2 has a corresponding bevel edge 211 corresponding to the tapered bevel edge 421. The present invention does not limit how the driven frame 2 forms the tapered edge 421, and the driven frame 2 in this embodiment describes by forming the corresponding inclined edge 211 by opening a notch 21, wherein the corresponding inclined edge 211 is one of the plurality of edges forming the notch 21.

Thus, as shown in fig. 2 with fig. 6, fig. 4 with fig. 7, and fig. 5 with fig. 8, when the daughter board M is plugged into the connector C, the block 42 with a smaller area enters the notch 21 with a larger area, and the tapered edge 421 corresponds to or is adjacent to the corresponding tapered edge 211. When the daughter circuit board M is to be removed, the handle 5 can be rotated about the second connecting portion 53 by pulling (pressing) the handle 5, the pushing portion 521 pushes the pushed portion 32 following the rotation of the handle 5, and the movable frame 4 can slide relative to the fixed frame 3 by the pushing; in addition, during the sliding process, the movable frame 4 drives the block 42 to move, so that the block 42 can push the corresponding bevel edge 211 by the tapered bevel edge 421, and the driven frame 2 is driven to pull out the sub-circuit board M from the connector C along the plugging direction by the tapered bevel edge 421 and the tapered bevel edge 211.

Because the pulling-out direction of the pulling-out mechanism of the utility model is parallel to the plugging-out direction when the sub-circuit board M is pulled out, the current fault that the connecting terminal in the connector C and the plugging part (such as most golden fingers) of the sub-circuit board M are damaged because the pulling-out direction is slightly different from the plugging-out direction can not occur, and the quick-release effect that the time for pulling-out is less is also provided.

In addition, in order to have a labor-saving effect when operating the pulling mechanism of the present invention, as shown in fig. 1, fig. 2 and fig. 6, the second connecting portion 53 of the handle 5 is disposed at a non-central position, so that the second connecting portion 53 can be used as a boundary to separate a first force arm section 51 and a second force arm section 52, the aforementioned pushing portion 521 is located at the second force arm section 52, and the length of the first force arm section 51 is greater than that of the second force arm section 52, thereby having a labor-saving effect when operating.

The removing mechanism of the present invention can also be used in the case of even number of sub-circuit boards M, for example, four sub-circuit boards M arranged in a matrix, or two sub-circuit boards M arranged one left side by one right side as shown in fig. 3 and 4. As shown in the figure, an even number of sub-circuit boards M are simultaneously fixed on the passive frame 2, and the corresponding bevel edge 211 of the passive frame 2 is located at the middle position of each sub-circuit board M. Therefore, only one single pulling mechanism of the utility model can pull out even number of sub-circuit boards M simultaneously.

In addition, as shown in fig. 3 and 4, the passive frame 2 may further fix a plurality of electronic products E (e.g., a storage device, etc.), so as to expand the functionality of the passive frame 2.

Naturally, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit or essential attributes thereof, and it is intended that all such changes and modifications be considered as within the scope of the appended claims.
