The inner and outer positions of screw hole 2 802 and screw hole 4 806 are corresponding. The number of screw holes 2 802 and screw holes 4 806 is the same.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, after adjusting the external assembly component 2, multiple sliders 804 are longitudinally inserted into the rectangular groove 801 and the reinforcing groove 810 on the surface of the mounting plate 7, so that the large limiting pieces 803 are embedded in the rectangular groove 801 and the small limiting pieces 807 are embedded in the reinforcing groove 810. Then, the screws 808 are rotated to connect the screw holes 809 and 806 to lock the position of the sliders 804 so as to connect to the upper machine head.

[0033] Sleeve blocks 609 are fixed on both sides of the top of the fixed plate 4, and insert rods 610 are horizontally inserted into the sleeve blocks 609. Bolts 608 are threaded to the front end of the sleeve blocks 609. A collar 605 is fixed to the outside of the side of the insert rod 610.

The spring 607 is sleeved on the outside of the guide rod 604 but does not contact it. The side of the guide rod 604 is embedded in the slot 603.

[0034] Specifically, such as Figure 1 and Figure 3As shown, after the head and beam snoot are installed through this connection structure, the insert rod 610 is moved laterally along the sleeve blocks 609 on both sides. After the rotating bolt 608 is tightened, the push block 606 and guide rod 604 are pushed inward along the slot 603 in the insert rod 610, the spring 607 is squeezed and the position of the push block 606 is adjusted. After the push block 606 is released, the springs 607 on both sides apply pressure to the center, so that the collars 605 on both sides are closed together with the slots 602 through the locking blocks 601 and clamped and fixed.

[0035] Working Principle: In use, this invention first adjusts the positions of the lever 205 and movable block 203 along the annular groove 3 and limiting frame 201 according to the connection status between the connecting structure and the beam slant. After aligning the movable block 203 with the screw hole 204, the bolt 207 is longitudinally screwed in to limit the position. The presence of the ball bearings 202 on both sides reduces frictional resistance. Based on installation requirements, the connection position of the external assembly component 2 is adjusted. Then, multiple sliders 804 are longitudinally inserted into the rectangular groove 801 and reinforcing groove 810 on the surface of the mounting plate 7, so that the large limiting pieces 803 are embedded in the rectangular groove 801, and the small limiting pieces 807 are embedded in the reinforcing groove 810. Then, the screw is rotated... The screw 808 connects to the screw holes 809 and 806, locking the position of the slider 804 to connect to the upper head. After the head and beam snoot are installed through this connection structure, the insert rod 610 is moved laterally along the sleeve blocks 609 on both sides. After the rotating bolt 608 is tightened, the push block 606 and guide rod 604 are pushed inward along the slot 603 in the insert rod 610, squeezing the spring 607 and adjusting the position of the push block 606. After releasing the push block 606, pressure is applied to the center by the springs 607 on both sides, so that the collars 605 on both sides are closed together by the locking block 601 and the locking groove 602, clamping and fixing the assembly block 5 and its internal objects on both sides.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
