[0025] The following provides a further explanation of the specific structures of the aforementioned fixing frame I and fixing frame II.

[0026] like Figure 2 , Figure 3 As shown, both the fixing frame I5 and the fixing frame II8 are composed of multiple horizontally, vertically and longitudinally arranged square tubes welded together. The vertically arranged square tubes are connected to the horizontally arranged square tubes or the longitudinally arranged square tubes by supporting square tubes.

[0027] The following provides a further explanation of the specific structure of the aforementioned intergovernmental organization.

[0028] like Figure 2 , Figure 4As shown, the centering mechanism consists of two opposing upper boom supports 4; the bottom end of the upper boom support 4 is hinged to the fixed frame I5, and can swing towards or away from the upper boom 400 on the fixed frame I5; the upper boom 400 is located between the two upper boom supports 4, and the top end of the upper boom support 4 is hinged to the upper boom 400, and the automatic centering function of the upper boom 400 is achieved by the upper boom supports 4 swinging on both sides.

[0029] In a further embodiment, the upper boom support 4 is an isosceles triangular frame structure with two hinge points at the bottom and one hinge point at the top. A single-ear hinge seat is fixed to the bottom end of the upper boom support 4, and a double-ear hinge seat is fixed to the bottom crossbeam of the fixed frame I5.

The upper ends are connected to the upper boom by bolts. This structural design is relatively stable, reducing the possible tipping tendency of the working device assembly (which includes the stick, middle boom, and upper boom) during transportation to a slight swaying tendency, thus realizing the anti-tipping function of the working device assembly; The hinged connection of the upper boom supports also allows the working device assembly to be quickly disassembled, and the completely consistent and symmetrical design of the upper boom supports on both sides enables the automatic alignment function of the upper boom and the tooling; Installing the rotating sleeve on the fixed support shaft as the upper boom support enables the rotating sleeve to rotate, thereby changing the upper boom support from a line support to a surface support, improving the overall stability.

[0035] The following provides a further explanation of the specific structure of the aforementioned clamping mechanism.

[0036] like Figure 3 , Figure 6 As shown, the clamping mechanism includes a front clamping mechanism and a rear clamping mechanism; the front clamping mechanism is detachably mounted on the base plate 15 of the fixed frame II8 and is used to clamp the rear support 14 fixed on the boom 300; the rear clamping mechanism spans across the two upper crossbeams of the fixed frame II8 and is detachably connected to the two upper crossbeams and is used to clamp the boom 300.

[0037] Further options, such as Figure 7 As shown, the front clamping mechanism is a pressure plate 9, which has through holes at both its front and rear ends. The base plate 15 of the fixing bracket II 8 has multiple threaded holes that correspond one-to-one with the through holes. The pressure plate 9 spans the rear bracket 14 and is fixed to the base plate 15 by multiple bolts.

[0038] Further options, such as Figure 8 As shown, the rear clamping mechanism includes a top frame 10, upper connecting plates 11 fixed at both ends of the top frame 10 along its length, and clamping components fixed in the middle area of ​​the bottom surface of the top frame 10; a lower connecting plate is fixed on the upper crossbeam of the fixed frame II 8, which is arranged opposite to the upper connecting plate 11. The clamping components include two oppositely arranged protrusions 12 and a pressure plate 13 fixed between the two protrusions 12. The stick 300 falls into the pressure plate 13 between the two protrusions 12. The upper and lower connecting plates are fixed together by detachable fasteners, and the pressure plate 13 clamps the stick 300.

[0039] As can be seen from the above, the front anti-tipping structure has the following functions and effects: Based on the mechanism of the boom, the front clamping mechanism and the rear clamping mechanism are designed to secure the working device assembly during transport, thereby improving the overall stability; at the same time, each structure is installed by bolt connection, which is convenient for disassembly, easy to operate, and highly efficient.

[0040] In use, the lower ends of the symmetrical upper boom supports on both sides are connected to the hinge seats on the fixed frame I with bolts to achieve rotation from 0° to 90°. The upper ends of the upper boom supports are connected and fixed to the upper boom with bolts. The rotating sleeve is installed on the support shaft, and then the installed rotating sleeve and support shaft are fixed to the two vertical beams of the fixed frame I with T-pins.

After the stick is placed on the fixed frame II, the pressure plate is placed in the rear bracket on the stick body. The pressure plate is fixed to the bottom plate of the fixed frame II with bolts. The rear clamping mechanism is then fixed to the upper crossbeam of the fixed frame II with bolts to achieve the fastening effect of the working device assembly and improve overall stability.
