At this time, the second end portion 344 is not pressed' and the first-button portion 316 and the second hook portion 346 are more likely to be buckled to define the critical position of the first end portion 342. In addition, an exposed upper surface 341 of the latch member 340 at this time is substantially parallel or coplanar with an exposed upper surface 321 of the cover 32'. Referring to FIG. 6, when the second end 344 of the latching member 34 is pressed, the latching member 340 is pivoted about the pivot 330 so that the first latching portion 316 (the latch) It is detached from the second hook portion 346 (the hook) without being engaged with the second hook portion 346. At this time, the torsion springs 35 〇 (shown in FIG. 4 ) are elastically deformed. The first end portion 342 of the latching member 34 突出 protrudes from the upper surface 321 of the cover 320 (the edge is shown in FIG. 3A ), and The cover 32 is detachable from the housing 31〇 against the above-described direction 400 (shown in FIG. 3A). It should be noted that, referring to FIG. 3A and FIG. 6, in this embodiment, when the second end portion 344 of the latching member 340 is pressed, the latching member 34 is folded on the cover 32Q. Therefore, the user can apply the latching member 34 〇 = - end '34 = against the external force of the above direction 4 (10) to push the relative direction _ relative to the housing 31G. Phase = the flexible snaps in the art are shown in the picture! As shown in Fig. 2), the user pushes the cover 此 in this embodiment to make the cover slid relative to the cover member 3, and the user is less laborious. In addition, referring to FIG. 5 and FIG. 6 , the cover 320 may further have a limiting portion 322 and a third locking portion 324 , and the locking member further has a fourth card at the second end portion 344 . Buckle 348. The position of the limiting portion 322 corresponds to the position of the first end portion 342, and the position of the third locking portion 324 corresponds to the position of the first end portion 344 and the limiting portion 322 and the third locking portion 324 are both The bump, and the fourth hook portion 348 is, for example, a dent corresponding to the third hook portion 324. As shown in FIG. 6, when the second end portion 344 of the latching member 34 is pressed such that the first latching portion 316 does not latch with the second latching portion 346, the third latching portion 324 interferes with the fourth portion. The buckle portion 348 defines a critical position after the second end portion is pressed and pressed. At this time, the interference torque generated by the third fastening portion 324 interfering with the fourth fastening portion 348 with respect to the pivot 33〇 is at least slightly larger than the torsional moment generated by the kinesos 3S0 (see │ 4). n) and the direction of the interference torque is opposite to the direction of the torsional moment to hold the first end portion 342 of the catch member 34 突出 in a state of protruding above the upper surface 321 of the cover 32 (see FIG. 4). It should be noted here that after the cover 32〇 (see FIG. 3a) is detached from the housing 310 (see FIG. 3A), if the user applies a slight force to the first end 342 of the snap member 34〇, The three latching portions 324 no longer interfere with the fourth latching portions 348'. The twisting of the torsion springs 350 (see item 4) will rotate the latching members 340 to return the latching members 340 to an initial position (see FIG. 3A). And the limiting portion 322 will abut the first end portion 342 to define a critical position committed by the first end portion 3. In summary, in the embodiment of the present invention, when the second end of the buckle member is pressed, the first end portion of the buckle member protrudes from the cover body. At this time, the user can apply an external force in the direction of sliding the cover body against the housing at the first end of the latching member to push the cover body to slide relative to the housing, thereby separating the cover body from the housing. . Therefore, (4) in the embodiment of the invention, the cover body allows the user to slide the cover body relative to the housing, which is less laborious. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the scope of the present invention, and it is possible to make a few changes without departing from the spirit and scope of the invention. The scope of the present invention is defined by the scope of the appended claims.
