[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] By arranging the first fixing component on the rectangular sleeve and the second fixing component on the clamping sleeve, the square tube sleeved in the rectangular sleeve and the square tube clamped in the clamping sleeve can be fixed, such as Figure 1-5 As shown, the building square tube fastener described in the present invention includes a rectangular sleeve 1 and a plug-in plate 302. A first fixing component 2 is provided on one side of the rectangular sleeve 1. The first fixing component 2 includes a first internally threaded sleeve 201 welded to both ends of one side of the rectangular sleeve 1. A first screw 202 is provided inside the first internally threaded sleeve 201. One end of the first screw 202 located inside the rectangular sleeve 1 is connected to a side plate 203 through a bearing.

[0026] A clamping sleeve 4 is provided on the top of the rectangular sleeve 1, and a second fixing component 5 is provided on the top of the clamping sleeve 4. The second fixing component 5 includes a second internally threaded sleeve 501 welded to both ends of the top of the clamping sleeve 4. A second screw 502 is provided through the inside of the second internally threaded sleeve 501. The bottom end of the second screw 502 located inside the clamping sleeve 4 is glued with a rubber block 503.

[0027] During use, tightening the first screw 202 pushes the side plate 203 to move, which can fix the rectangular sleeve 1 on the outside of the vertical square tube, inserting the plug plate 302 into the docking sleeve 301, so that the clamping sleeve 4 clamps the horizontal square tube on the rectangular sleeve 1, tightening the fixing bolt 305 to fix the clamping sleeve 4, and tightening the second screw 502 can fix the horizontal square tube in the clamping sleeve 4.

[0028] For example, Figure 3 、 Figure 5 As shown, the present invention further includes connecting components 3 provided on both sides of the rectangular sleeve 1 , and the connecting components 3 include docking sleeves 301 welded to both sides of the rectangular sleeve 1 and plug-in plates 302 welded to both ends of the bottom of the clamping sleeve 4 .

[0029] During use, when the plug board 302 is inserted into the docking sleeve 301 , the clamping sleeve 4 is clamped on the top of the rectangular sleeve 1 .

[0030] For example, Figure 5 As shown, the present invention also includes: third internal threaded sleeves 304 are welded at both ends of one side of the docking sleeve 301; fixing bolts 305 are inserted through the interior of the third internal threaded sleeve 304; and clamping holes 303 are equidistantly opened on one side of the plug-in plate 302.

[0031] When in use, the fixing bolt 305 is tightened so that one end thereof is inserted into the clamping hole 303 , thereby fixing the plug board 302 inserted into the docking sleeve 301 .

[0032] For example, Figure 2 As shown, the present invention further includes that the side plate 203 is welded with latch teeth 204 at equal distances on a side away from the first screw rod 202 .

[0033] When in use, the arrangement of the latching teeth 204 enables the side plate 203 to be firmly attached to one side of the square tube.

[0034] For example, Figure 2 、 Figure 3 As shown, the present invention further includes: a first rubber pad 6 glued to the inner side of the rectangular sleeve 1; and a second rubber pad 7 glued to the inner side of the clamping sleeve 4.

[0035] During use, the first rubber pad 6 and the second rubber pad 7 play an anti-slip role.

[0036] For example, Figure 1 As shown, the present invention also includes that the rectangular sleeve 1, the connecting assembly 3, the plug-in board 302 and the clamping sleeve 4 are all made of stainless steel.

[0037] When in use, the rectangular sleeve 1, the connecting assembly 3, the plug-in plate 302 and the clamping sleeve 4 made of stainless steel have high strength and are not easily deformed or corroded.

[0038] When the utility model is used, a person puts the rectangular sleeve 1 on the top of the vertical square tube, and uses a tool to rotate the first screw 202. The first screw 202 rotates through the first internally threaded sleeve 201 to push the side plate 203 to move, so that it is close to one side of the vertical square tube, thereby fixing the rectangular sleeve 1 on the outside of the vertical square tube;

[0039] Place the horizontal square tube on top of the rectangular sleeve 1, then insert the plug plate 302 into the docking sleeve 301, so that the clamping sleeve 4 is clamped on the horizontal square tube. Turn the fixing bolt 305 to move through the third internal threaded sleeve 304 so that one end of the fixing bolt 305 is inserted into the corresponding clamping hole 303, and the clamping sleeve 4 can be fixed to the top of the rectangular sleeve 1, thereby clamping the horizontal square tube on the top of the rectangular sleeve 1;

[0040] The second screw rod 502 is rotated using a tool to push the rubber block 503 downward through the second internal threaded sleeve 501 , thereby fixing the horizontal square tube engaged in the tube sleeve 4 .
