[0028] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0029] like Figure 1 As shown, a multi-purpose fuel cell test bench includes a test bench 1. The top of the test bench 1 is formed with a groove. A work plate 2 is disposed in the groove. An instrument 4 is placed above the work plate 2. The bottom of the instrument 4 is in contact with the work plate 2 and extends outward to form a protruding edge 41.

[0030] A plurality of limit grooves 21 are provided at intervals on the top surface of the work plate 2, and a limit member 3 is detachably connected in the limit groove 21; an elastic member is provided at the bottom of the limit groove 21, and a plurality of insert pieces 25 are provided at intervals from top to bottom on the top inner wall of the limit groove 21; the limit member 3 includes a top cover 31 at the top and a rotating column 32 at the bottom, and a plurality of insert pieces 34 are provided at intervals from top to bottom on the outer wall of the rotating column 32.

[0031] According to the technical solution in the above paragraph, when in use, the instrument 4 to be used is placed above the work board 2 to ensure that the protruding edge 41 at the bottom of the instrument 4 is in contact with the top surface of the work board 2. Then the rotating column 32 can be inserted into the limiting groove 21 closest to the protruding edge 41. The elastic member contracts after being subjected to force until the edge of the top cover 31 is tightly in contact with the protruding edge 41. Then the rotating column 32 is rotated to insert the second plug 34 into the gap between the adjacent plugs 1 25. When the protruding edges 41 in other directions of the instrument 4 are all limited and fixed by the top cover 31, the installation is completed. When the instrument 4 needs to be disassembled, the rotating column 32 is rotated to separate the second plug 34 from the first plug 25. At this time, the rotating column 32 and the top cover 31 are both pushed out under the action of the elastic member, and the instrument 4 can be taken away.

[0032] As an example, Figure 1 As shown, universal wheels 12 are installed at the bottom of the stand 1 to facilitate the movement of the stand 1; an exhibition board 11 is installed on one side of the top of the stand 1, and the exhibition board 11 can be used to hang a display screen to display the operating steps, or to hang the tools needed; a drawer 13 is also provided on the side of the stand 1 facing the user.

[0033] As an example, Figure 2 、 Figure 3 As shown, the limit groove 21 is a circular groove, with the middle of the depth of the limit groove 21 as the dividing line, the limit groove 21 is lower than the middle as the bottom, and the limit groove 21 is higher than the middle as the top; the bottom inner wall of the limit groove 21 is provided with a sliding groove 23 corresponding to the position of the elastic member, and the sliding groove 23 is provided with at least two locations, the two sliding grooves 23 are symmetrically arranged, and a limit plate 24 is provided between the two sliding grooves 23, the limit plate 24 can reciprocate along the sliding groove 23, and the elastic member is installed in the space formed between the limit plate 24 and the bottom of the limit groove 21; under the action of the elastic member, the limit plate 24 is always in contact with the lowest insert 25 in the limit groove 21; when the rotating column 32 is pressed down, the elastic member contracts, and the limit plate 24 is forced to move downward synchronously to ensure balanced force.

[0034] The above solution is further refined, and the elastic member is a spring 22 .

[0035] As an example, Figure 4 、 Figure 5As shown, the rotating column 32 is a cylinder, the diameter of the rotating column 32 is smaller than the diameter of the top cover 31, and multiple second inserts 34 are installed on the outer wall of the rotating column 32 near one end of the top cover 31; when the rotating column 32 is inserted into the limiting groove 21, the position of the second insert 34 and the position of the first insert 25 are offset from each other.

[0036] According to the technical solution in the previous paragraph, after determining the position of the instrument 4, the rotating column 32 is inserted into the limiting groove 21 so that the edge of the top cover 31 coincides with the protruding edge 41, and the insertion is continued until the bottom surface of the top cover 31 abuts against the protruding edge 41, and the rotating column 32 can no longer be pressed down further. At this time, the rotating column 32 is rotated so that the plug-in piece 1 25 and the plug-in piece 2 34 at the corresponding position are engaged with each other, completing the locking of the limiting member 3, and also achieving the limitation of the protruding edge 41 of the instrument 4; and when the instrument 4 needs to be disassembled, the rotating column 32 is reversed to separate the plug-in piece 1 25 and the plug-in piece 2 34 from each other. At this time, the limiting member 3 is ejected under the action of the spring 22.

[0037] The above scheme is further refined. In this scheme, two groups of insert pieces 1 25 and insert pieces 2 34 are provided. The two groups of insert pieces 1 25 are symmetrically arranged, and the two groups of insert pieces 2 34 are symmetrically arranged. The thickness of the insert pieces 2 34 is smaller than the spacing between adjacent insert pieces 1 25, so that it is easier to rotate the rotating column 32 to insert the insert pieces 2 34 into the spacing between the insert pieces 1 25.

[0038] To further refine the above solution, a notch 33 is formed on the top surface of the top cover 31 for easy gripping, so that the user can rotate the top cover 31 and thereby drive the rotating column 32 to rotate.

[0039] The above solution is further refined. Rubber blocks 35 are arranged at circumferential intervals along the bottom edge of the top cover 31. Depending on the thickness of the protruding edge 41, the depth of the rotating column 32 inserted into the limit groove 21 is also different. When the bottom surface of the top cover 31 abuts the protruding edge 41, the rubber blocks 35 can increase the friction force to prevent the instrument 4 from shaking during use.

[0040] The above solution is further refined by rounding the bottom end of the rotating column 32 to provide guidance during insertion and make it easier.

[0041] As an example, Figure 6As shown, a mounting bracket 5 is installed on the outer wall of the stand 1, and the mounting bracket 5 is installed on the top of the stand 1 by screws. The mounting bracket 5 is a hollow rectangular structure, and an opening 51 is provided on the side of the mounting bracket 5 facing the user. A plurality of card slots 52 are spaced apart on the top of the mounting bracket 5, and the size of the card slot 52 is larger than the diameter of the rotating column 32, and the card slot 52 is connected to the opening 51; when the limit member 3 is not needed, since there is a gap X between the second plug-in piece 34 at the top of the rotating column 32 and the top cover 31, the limit member 3 can be placed in the opening 51, and the gap X here is plugged into the card slot 52, so that the limit member 3 is suspended on the mounting bracket 5, which is convenient for the user to take.
