[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Example 1:
[0036] Please see Figure 1 - Figure 7 As shown, a tool for facilitating the replacement of single-column high support components during production and maintenance includes:
[0037] The base 1 has a support assembly fixedly connected to one side of its top end. The support assembly includes a connecting seat 5, a movable column 6, a rotating disk 7, and a screw 8. The top end of the support assembly is fixedly connected to a connecting column 9. A placement device 2 is fixedly inserted and connected to the outer surface of the connecting column 9. A cushion mechanism 3 is connected to the top end of the connecting column 9 by a bearing.
[0038] Depend on Figure 1 - Figure 4It can be seen that the movable column 6 is movably inserted into the connecting seat 5, the rotating disk 7 is bearing connected to the top of the movable column 6, the screw 8 is threadedly connected to the top of the rotating disk 7, the connecting seat 5 is fixedly connected to the top of the base 1, and the screw 8 is fixedly connected to the bottom of the connecting column 9. The bottom of the screw 8 passes through the rotating disk 7 and extends into the movable column 6, thus allowing the screw 8 to be stored. The top of the base 1 has a groove 10, and both sides of the inner wall of the groove 10 have sliding grooves 11. A slide seat 17 is movably inserted into the groove 10, and a support rod 15 is movably inserted into the slide seat 17 via a rotating shaft. The end of the support rod 15 away from the slide seat 17 is movably inserted into a fixed seat 14. The fixed seat 14 and the support rod 15 are connected to the fixed seat 14. A positioning rod 16 is movably interwoven between the rods 15. Two positioning holes 4 are opened on both sides of the top of the base 1, and a positioning frame 18 is movably interwoven between the two vertical positioning holes 4. Two first limit frames 19 are movably interwoven on the outer surface of the positioning frame 18. Slider 20 is movably interwoven in the two sliding grooves 11. The bottom end of the positioning frame 18 is movably interwoven with the two sliders 20. The fixed seat 14 is fixedly connected to the movable column 6. A connecting groove 21 is opened at the bottom of the base 1. A pull rod 22 is movably interwoven between the two sides of the inner wall of the connecting groove 21. The pull rod 22 facilitates the handling of the device. Mounting plates 12 are fixedly connected to both ends of the base 1. Multiple climbing frames 13 are fixedly connected at equal intervals on the outer surface of the movable column 6.
[0039] As can be seen from the above, when the movable column 6 is pulled, it rotates within the connecting seat 5, changing from a horizontal to a vertical position. Simultaneously, the movable column 6 pulls the fixed seat 14, which is fixedly connected to it, to move. The fixed seat 14 then pulls the support rod 15, which is fixedly connected to it, to move. The other end of the support rod 15 rotates within the slide 17 and pulls the slide 17 to slide within the groove 10. The slide 17 drives the slider 20, which is fixedly connected to it, to slide within the slide groove 11. After sliding to a fixed position, the positioning frame 18 passes through the positioning hole 4 and is inserted and connected to the two sliders 20, thereby limiting the position of the slide 17. This allows the support rod 15 to stably support the movable column 6, making the device foldable for transport and unfolded for use. It is highly flexible, convenient for transport, and suitable for use in rugged mountainous terrain. It also facilitates the operation, maintenance, and replacement of mountain high support components.

The second movable slots 95 are movably connected to the two folding frames 96 respectively.
[0042] The folding frame 96 includes a movable plate 961, a fixing groove 962, a connecting frame 963, a magnetic suction plate 964, and a placement pad 965. The fixing groove 962 is located at the bottom of the movable plate 961, the connecting frame 963 is fixedly connected to the top of the movable plate 961, the magnetic suction plate 964 is fixedly inserted into the bottom of the connecting frame 963, and the placement pad 965 is fixedly connected to the top of the magnetic suction plate 964. The fixing groove 962 and the movable support 93 are movably inserted together.
[0043] As can be seen from the above, pulling the folding frame 96 and the movable support 93 causes them to rotate within the first movable slot 92 and the second movable slot 95, respectively. This adjusts the folding frame 96 to a horizontal position, and one end of the movable support 93 is inserted into the folding frame 96 and fixed by the positioning post 97. This puts the device into a usable state, assisting workers in disassembly. Parts are placed in the connecting frame 963 on one side and positioned by the magnetic suction plate 964. The disassembled parts and accessories can be placed in another connecting frame 963 and positioned by the magnetic suction plate 964 in the other connecting frame 963, improving operational safety and reducing the risk of parts loss.
[0044] Preferably, the fixing plate 94 is fixedly inserted and connected to the outer surface of the connecting column 9, and the folding frame 96 and the movable bracket 93 are movably inserted and connected by the positioning column 97.
[0045] One end of the movable plate 961 is movably inserted into the second movable slot 95 via a rotating shaft.
[0046] As can be seen from the above, the movable bracket 93 and the folding frame 96 can be fixed by the positioning column 97, so that the movable bracket 93 can support the folding frame 96.
[0047] Example 3:
[0048] refer to Figure 7As shown, the cushion mechanism 3 includes a support base 31, with a second limiting frame 34 fixedly connected to both ends of the support base 31.

A storage groove 35 is opened at one end of the support base 31, and a storage box 36 is movably inserted and connected in the storage groove 35. The connecting rod 32 is inserted and connected to the connecting column 9 by a bearing. Two limiting grooves 37 are opened on both sides of the inner wall of the storage box 36, and a sliding box 38 is movably inserted and connected between the two limiting grooves 37.
[0049] As can be seen from the above, the connecting rod 32 and the connecting column 9 are movably interlocked together, so that the direction can be adjusted as needed during the operation. Pulling the storage box 36 moves the storage box 36 out of the storage slot 35. The tools used are placed in the storage box 36 and the sliding box 38. Pulling the sliding box 38 makes it slide between the two limiting slots 37, so that the position of the sliding box 38 can be moved to facilitate the retrieval of tools. The user straddles the top of the soft pad 33 through the climbing frame 13, located between the two second limiting frames 34, and disassembles the single column high support assembly through the tools in the storage box 36 and one of the connecting frames 963.
