Detailed Description
As shown in fig. 1 and 2, the utility model comprises a positioning sleeve 1, wherein the cross section of the positioning sleeve 1 is rectangular, a welding operation port 2 is formed in the middle of the positioning sleeve 1, a first propping mechanism 3 and a second propping mechanism 4 are respectively and simultaneously arranged at two ends of the positioning sleeve 1, the first propping mechanism 3 is positioned on one side surface of the positioning sleeve 1, and the second propping mechanism 4 is positioned on the side surface adjacent to the first propping mechanism 3.
As long as the size of the square tube 6 is smaller than the size of the inner wall of the positioning sleeve 1, positioning and welding operation can be performed through the positioning sleeve 1, and four side faces of the positioning sleeve 1 enclose a rectangle, so that any two adjacent side faces on the positioning sleeve 1 can be used as reference faces for positioning the square tube 6, and only the side faces of the square tube 6 are attached to the side faces of the positioning sleeve 1.
Wherein, first tight mechanism 3 and the tight mechanism 4 of second top all include threaded connection's jack bolt 5 on the spacer sleeve 1 lateral wall, can adjust its inside length that stretches into spacer sleeve 1 through rotatory jack bolt 5 to with the side of square pipe 6 top leaning on spacer sleeve 1 that is located in the spacer sleeve 1.

Preferably, a top plate is provided at the end of the jack bolt 5, and the jack bolt 5 is in surface contact with the square tube 6 through the top plate, so that the jack force is uniformly applied to the surface of the square tube 6, and the end of the jack bolt 5 is prevented from extruding and deforming the surface of the square tube 6 when the force required for fixing the square tube 6 is large. For the square pipe 6 having a short length, the top plate may be omitted and the end of the jack bolt 5 may be directly brought into contact with the surface of the square pipe 6.
The welding operation port 2 is a notch formed by removing the material of the rectangular part on the top surface of the positioning sleeve 1 and removing the material of the inverted trapezoid part on the two side surfaces respectively. The welding operation port 2 should be as large as possible to facilitate the welding operation while ensuring the overall structural strength of the positioning sleeve 1. So the inverted trapezoid material is removed at the two sides, and a part of material is remained between the welding operation port 2 and the bottom surface of the positioning sleeve 1, and the part of material plays the role of reinforcing ribs, thereby preventing the middle part of the positioning sleeve 1 from bending when being stressed.
Since the square tube 6 has a smaller size than the positioning sleeve 1 and the square tube 6 is fixed at a right angle to one side of the top of the positioning sleeve 1, in order to ensure that as many square tubes 6 as possible can be aligned using the present utility model, the first tightening mechanism 3 is disposed near the top surface of the positioning sleeve 1, and the second tightening mechanism 4 is disposed near the opposite side of the surface of the first tightening mechanism 3.
