Namely, the distance between the two parallel second limiting parts on the same horizontal plane is larger than the distance between other parts of the two second limiting parts, so that the base can be conveniently clamped in.
Please refer to fig. 3, which is a side view of the lower slot body of the card slot. The limiting member 122 is vertically connected with the positioning member 121, the limiting member 122 includes a first limiting member 1221 and a second limiting member 1222, and the first limiting member 1221 is connected with the second limiting member 1222. The first stopper 1221 has a rectangular shape, and the width of the second stopper 1222 facing the center of the card slot 1 gradually decreases from inside to outside along the extending direction of the second stopper 1222 facing away from the positioning member 121. The distance between the open ends of the two parallel second limiting members 122 positioned on the same horizontal plane is larger than the distance between other parts of the two second limiting members 122, so that the base 5 can be conveniently clamped in. The distance between the two limiting pieces is a, and the distance between the two limiting pieces is b, wherein a is more than b. In this embodiment, the distance a between the base 5 and the locking device is set. If the second stopper 1222 is rectangular, the distance between the base 5 and the stopper is b. The second limiting piece is shaped so as to facilitate the clamping in of the base 5.
The upper groove body is of a U-shaped structure, is connected with the lower groove body and is positioned above the base, protrudes inwards relative to the lower groove body and is used for limiting the movement of the base on the Z axis. The upper groove body opening end is provided with the circular arc angle towards draw-in groove center one side, and the circular arc angle is used for making things convenient for the installation of base and draw-in groove to be connected.
Specifically, the upper groove body is of a U-shaped structure, the upper groove body is connected with the lower groove body and is arranged at the upper position of the lower groove body, and when the base is clamped with the clamping groove, the upper groove body is positioned at the upper position of the base. The upper groove body protrudes inwards relative to the lower groove body so that the inner diameter of the upper groove body is smaller than the length of the base, thereby limiting the movement of the base on the Z axis. In addition, the upper groove body opening end is provided with the circular arc angle towards draw-in groove center one side, and the circular arc angle is used for making things convenient for the installation of base and draw-in groove to be connected.
Fig. 4 is a top view of the engagement between the slot and the base. The base 5 is provided with I-steel, and the length of the I-steel is smaller than that of the base 5. The upper tank 11 has a U-shaped structure, and the outer side of the upper tank is aligned with the outer side of the lower tank 12. The upper groove body 11 protrudes inwards relative to the lower groove body 12, and the inner diameter of the upper groove body 11 is slightly larger than the length of the I-steel and smaller than the length of the base 5, so that the I-steel can be clamped. When the base 5 is clamped with the clamping groove 1, the upper groove body 11 is positioned above the base 5 and is clamped with the I-steel. The open end of the upper groove body 11 is provided with an arc angle 111 towards the center of the clamping groove 1, and the arc angle 111 is used for facilitating the installation connection between the base 5 and the clamping groove 1. The principle is similar to the shape setting of the second limiting piece. Let the outer length of the upper tank 11 be c and the inner diameter of the upper tank be d, where c > d. When the arc angle 111 is set, the clamping range distance of the I-steel is c; when the arc angle 111 is not provided, the distance between the ranges where the I-steel is clamped is d. It is obvious that the distance between the clamping ranges of the arc angles 111 is larger, so that the clamping of the I-steel is more convenient.
The supporting device further comprises a pin shaft, a mounting hole matched with the pin shaft is formed in the base, and the pin shaft is assembled in the mounting hole and used for limiting the movement of the base on the X axis.
Referring to fig. 2, 4 and 5, the base 5 is provided with a mounting hole 51 matched with the pin 6, and the pin 6 is fitted in the mounting hole 51 and used for limiting the movement of the base 5 in the X-axis. When the base 5 is engaged with the clamping groove 1, the clamping groove 1 has an opening structure, and when the gravity acts on the base 5, the base can still easily slide out of the opening structure of the clamping groove 1. Therefore, the pin shaft 6 is arranged, when the pin shaft 6 is assembled in the mounting hole 51, the base 5 and the clamping groove 1 are clamped, and even if the base 5 is subjected to the action of gravity, the base 5 cannot slide out from the opening structure of the clamping groove 1, so that the movement of the base 5 on the X axis is limited.
The number of the standard modules is multiple, and in any two adjacent standard modules, the base of the standard module positioned at the upper part is detachably connected with the clamping groove on the standard module positioned at the lower part.

In any two adjacent standard modules 4, the base 5 of the standard module 4 positioned at the upper part is detachably connected with the clamping groove 1 on the standard module 4 positioned at the lower part.
The connection mode between the clamping groove and the standard module and/or between the clamping groove and the main deck is welding. The adoption of a welded connection mode can enable connection between the clamping groove and the standard module and connection between the clamping groove and the main deck to be firmer.
In this embodiment, the draw-in groove welds on the top and the main deck of standard module respectively, and the bottom of standard module and the bottom of basic module are equipped with the base. The base slides into the clamping groove through the opening structure of the clamping groove to realize clamping and the pin shaft is assembled in the mounting hole of the base to realize fixation. Between two adjacent standard modules, a base positioned at the bottom of the standard module is clamped with a clamping groove positioned at the top of the standard module below and is fixed through a pin shaft; between the basic module and the standard module, a base positioned at the bottom of the basic module is clamped with a clamping groove positioned at the top of the standard module and is fixed through a pin shaft; and a base positioned at the bottom of the standard module is clamped with a clamping groove positioned on the main deck and is fixed through a pin shaft between the standard module and the main deck.
