When the aluminum square bar 1 needs to be removed, the connecting handle 31 is pressed and rotated downward, and the connecting seat 33 at the lower end moves back into the fixing groove 25.

[0038] As Figures 1-10As shown, the head mounting mechanism 4 includes a mounting box 40 connected with the plug-in slot 11, a connecting slot 41 is formed on one side of the mounting box 40, a reset spring 43 is fixedly connected at one end of the mounting box 40 away from the connecting slot 41, the other end of the reset spring 43 is fixedly connected with a fixed block 44, the fixed block 44 is fixedly connected between the aluminum square tube 1, a moving block 42 is fixedly connected on one side of the mounting box 40, two adjacent aluminum square tubes 1 are aligned end to end, and the moving block 42 is pushed out of the plug-in slot 11 by two hands, when a certain section of the aluminum square tube 1 needs to be replaced due to damage, the push block 410 is pushed by two hands, so that the two clamping blocks 47 are rotated and adjusted to be parallel, after the clamping block 47 is rotated and adjusted to be parallel, the reset spring 43 is no longer limited by the force, and the mounting box 40 on the corresponding side can be pulled to slide into the plug-in slot 11, and then the worker can release the fixing between the two aluminum square tubes 1; the connecting base 45 is fixedly connected in the mounting box 40, the limiting ring 46 is fixedly installed on the connecting base 45, the top block 411 is fixedly connected on one side of the limiting ring 46, the top block 411 is wedge-shaped on the side away from the limiting ring 46, the clamping block 47 is rotatably connected to the upper surface of the connecting base 45, the fixed long rod 48 is fixedly connected at one end of the clamping block 47, the positioning block 49 is installed on the fixed long rod 48, the push block 410 is fixedly connected on the side of the fixed long rod 48 away from the clamping block 47, the push block 410 is slidably connected with the second mounting slot 13, the spring assembly 5 is installed in the mounting box 40, the positions of the head mounting mechanism 4 in the two adjacent aluminum square tubes 1 are arranged in axial symmetry, therefore, the clamping blocks 47 in the two adjacent aluminum square tubes 1 can be rotated and adjusted to be parallel when contacting the wedge surface of the top block 411 of the other party, when the parallel surfaces of the two clamping blocks 47 complete the contact, the two limiting rings 46 form a circle, and the fixed long rod 48 is rotated and restored to an inclined state under the spring tension of the spring assembly 5, thereby fixing and clamping the two adjacent aluminum square tubes 1.

[0039] As Figures 1-11As shown, the spring assembly 5 includes a mounting seat 50 fixedly mounted with the mounting box 40, a connecting portion 51 rotatably connected in the mounting seat 50, a spring box 52 fixedly connected at one end of the connecting portion 51, a moving rod 53 slidably connected in the spring box 52, a mounting spring 54 sleeved outside the moving rod 53, the mounting spring 54 being fixedly connected at two ends thereof with the moving rod 53 on one side and the inner wall of the spring box 52 respectively, a connecting head 55 fixedly connected at the end of the moving rod 53 away from the connecting portion 51, a connecting ring 56 fixedly mounted on the connecting head 55, and the connecting ring 56 being annularly connected between the locating block 49. When the clamping block 47 is subjected to a pressure tending to be parallel, the fixed long rod 48 rotates and further drives the moving rod 53 to compress the mounting spring 54 to slide. When the pressure tending to be parallel disappears, the mounting spring 54 can push the moving rod 53 on one side to slide into the spring box 52 away from the end of the fixed long rod 48, so that the connecting head 55 drives the fixed long rod 48 to move, and further, the limiting ring 46 can rotate to recover to the inclined state.

[0041] The working principle of the embodiment is as follows. When it is necessary to splice and combine the aluminum square duct 1, two groups of aluminum square ducts 1 to be spliced are placed in the same horizontal position and are respectively named aluminum square duct 1-1 and aluminum square duct 1-2.

When the parallel surfaces of the two clamping blocks 47 complete contact, the two limiting rings 46 form a circle, and the fixed long rod 48 rotates to recover to an inclined state under the spring tension of the spring assembly 5, so as to fix and lock the aluminum square duct 1-1 and the aluminum square duct 1-2. Repeating the operation can connect multiple groups of aluminum square ducts 1.

[0043] When a certain section of the aluminum square 1 needs to be replaced due to damage, the push block 410 is simultaneously pushed by both hands, so that the two clamping blocks 47 are rotated and adjusted to be parallel. When the clamping blocks 47 are rotated and adjusted to be parallel, the reset spring 43 is no longer subjected to the limiting force, and the installation box 40 on the corresponding side can be pulled to slide into the insertion slot 11.

The connecting handle 31 is rotated, the connecting seat 33 at the lower end of the mounting column 30 is driven out of the fixed slot 25, the connecting handle 31 is loosened, the fixing spring 36 pushes the limiting plate 32 upward, the limiting plate 32 drives the mounting column 30 and the connecting seat 33 to move upward, and then the limiting blocks 34 at both ends of the connecting seat 33 move upward to tightly fit the inner wall of the aluminum square 1, so that the aluminum square 1 and the keel 2 are fixed. When the aluminum square 1 needs to be removed, the connecting handle 31 is pressed downward and rotated in the opposite direction, so that the connecting seat 33 at the lower end moves back into the fixed slot 25.
