It can be appreciated that when the limiting portion 150 is at the limiting position, the first pin 151 and the second pin 152 are simultaneously abutted against the base 110, so as to limit the movement of the second locking portion 130. The fixing member 200 can apply a driving force to the first pin 151, and the first pin 151 can drive the second pin 152 after obtaining the driving force, so that the second pin 152 is separated from the abutment with the base 110, and the limiting portion 150 is located at the release position. It will be appreciated that the mount 200 is capable of driving the movement of the first pin 151, and that the movement of the first pin 151 can further drive the movement of the second pin 152 so that the second pin 152 can be moved out of abutting relationship with the base 110. To further fix the position of the first locking portion 120 relative to the base 110, in some embodiments, when the limiting portion 150 is in the limiting position, the second locking portion 130 may abut against the first locking portion 120, so that the first locking portion 120 is located in the first position. It should be noted that the limit position and the release position may correspond to different positions of the limit portion 150 with respect to the base 110, and the explanation will not be repeated here.

For the embodiment of the multiple locking base structure 100 described above that includes the stop 150. To facilitate positioning of the stopper 150 in the stopper position or the release position, the multiple locking base structure 100 may further include a structure capable of driving the stopper 150. For convenience of description, the following embodiment taking the limiting structure as the pin is taken as an illustration, and different embodiments can be combined with each other between different technical schemes. In particular, referring to fig. 9-10, the multiple locking base structure 100 may further include a first spring 160 and a second spring 170. One end of the first elastic piece 160 may be connected to the base 110, and the other end may be connected to the first pin 151. The first elastic piece 160 is configured to be capable of driving the first pin 151 to a position abutting against the base 110, one end of the second elastic piece 170 is connected to the second locking portion 130, the other end is connected to the second pin 152, and the second elastic piece 170 is configured to be capable of driving the second pin 152 to a position abutting against the base 110. It will be appreciated that in some embodiments, the first elastic piece 160 can generate an elastic force that drives the first pin 151 to a position abutting against the base 110, and the second elastic piece 170 can generate an elastic force that drives the second pin 152 to a position abutting against the base 110, so that after the first pin 151 or the second pin 152 is out of abutting against the base 110, it can be located again to a position abutting against the base 110 under the elastic force of the first elastic piece 160 or the second elastic piece 170.

In order to make the mounting of the fixing member 200 more stable when the multiple locking base structure 100 is in the second state. The displacement of the fixing member 200 in a direction away from the multiple locking base structure 100 may be further limited, and referring to fig. 1-2, in some embodiments, the base may be provided with a bevel, where the bevel forms an angle with the wall of the fixing member 200 contacting the base 110, and the specific angle arrangement may be adapted to fixing members 200 of different specifications. During movement of the securing member 200 in a direction away from the multiple locking base structure 100, the ramp can abut the securing member 200 and limit displacement of the securing member 200. In addition, the displacement of the securing member 200 on the wall surface in contact with the multiple locking base structure 100 may be further limited, as shown in fig. 2, and in some embodiments, the base may be further provided with a drop-out prevention screw 180. In some embodiments, the anti-falling screw 180 may be disposed on a wall surface where the fixing member 200 contacts the multiple locking base structure 100, and the fixing member 200 may contact the anti-falling screw 180 during the moving process of the fixing member 200 on the wall surface of the base 110, so that the anti-falling screw 180 may prevent the fixing member 200 from falling off from the base 110.

From the combination of the above embodiments, it can be derived that, referring to fig. 5-12 (the installation process can be understood as the process from fig. 5-8), in some embodiments, the specific manner of installing and connecting the fixing member 200 to the multiple locking base structure 100 can be: when the multiple locking base structure 100 is in the first state, the fixing piece 200 is placed in the installation cavity of the base 110, the first locking part 120 is located at the first position and has an installation gap with the fixing piece 200, and the fixing piece 200 can press the first pin shaft 151 while contacting and abutting with the base 110; the first pin shaft 151 can drive the second pin shaft 152 after acquiring the pressing driving force, so that the second pin shaft 152 is separated from the abutment with the base 110; at this time, the second locking portion 130 is no longer constrained by the second pin 152, and the second locking portion 130 is separated from the abutment with the first locking portion 120 and moves along the first direction X due to the elastic force of the second elastic member 144; because the second locking portion 130 is separated from the position of abutting the first locking portion 120, the movement of the first locking portion 120 along the first direction X is no longer constrained by the second locking portion 130, the first locking portion 120 is acted by the elastic force of the first elastic member 141, and moves from the first position to the second position along the first direction X and abuts against the fixing member 200, so that the elastic force of the first elastic member 141 can act as the clamping force of the multiple locking base structure 100 to the fixing member 200; the first driving piece 142 extends into the opening of the first locking part 120 along the first direction X, so that the first driving piece 142 can be connected with the base 110 through threads and is abutted against the abutting surface, and the displacement of the first locking part 120 along the reverse direction of the first direction X is limited; under the combined action of the elastic force of the first elastic member 141 and the abutment of the first driving member 142 to the first locking portion 120, the fixing member 200 can be stably installed and connected to the multiple locking base structure 100, and the multiple locking base structure 100 is in the second state.

Accordingly, referring to fig. 5-12 (the separation process may be understood as the process of fig. 8-5), in some embodiments, the specific manner of separating the securing member 200 from the fixed connection of the multiple-locking base structure 100 may be: when the multiple locking base structure 100 is in the second state, the first locking portion 120 is located at the second position and abuts against the fixing member 200 (the first locking portion 120 clamps the fixing member 200), and drives the first driving member 142 in the reverse direction of the first direction X, so that the first driving member 142 is out of abutting contact with the first locking portion 120; the second driving piece 143 is driven in the reverse direction of the first direction X, so that the second driving piece 143 can abut and drive the first locking part 120 to overcome the elastic force of the first elastic piece 141, and the first locking part 120 can move from the second position to the first position; in the process of the reverse movement of the second locking portion 130 along the first direction X, under the elastic force of the second elastic piece 170, the second pin 152 can move to a position where it is simultaneously abutted against the base 110 and the first pin 151; under the combined action of the abutting force of the second pin 152 and the elastic force of the first elastic piece 160, the first pin 151 can move to a position abutting against the base 110; the second pin 152 abutting against the base 110 can limit the second locking portion 130 to move reversely along the first direction X, and enable the second locking portion 130 to be located at a position abutting against the first locking portion 120, so that the first locking portion 120 can overcome the elastic force of the first elastic member 141 and be located at the first position, and at this time, the multiple locking base structure 100 is in the first state.
