[0021] The support assembly includes a fixed tube 9, in which a support rod 4 is inserted to slide with the fixed tube 9, and a support block 5 is fixed to the movable end of the support rod 4, and the support block 5 is an arc-shaped structure, which is convenient for adjusting the length according to the size of the inspection well and increasing the fitting area with the inspection well wall, thereby improving stability and achieving better protection effect;

[0022] The outer side of the support block 5 is covered with an elastic protective cover 6, and a sliding assembly is arranged between the support block 5 and the protective cover 6, which is convenient for further increasing the supporting effect on the inspection well wall, and is convenient for adjustment according to the size of the inspection well, and is also convenient for protecting the support block 5 and the sliding assembly to prevent impurities from damaging them and affecting their use;

[0023] The front end of the cylinder 1 is provided with an adjustment component for driving the support rod 4 to slide in the fixed tube 9 at the same time, which is convenient for installation and disassembly, and also convenient for adjustment of inspection wells of different sizes for protection.

[0024] like Figure 1 and Figure 2 As shown, the vertical section of the support block 5 is a "T"-shaped structure, and the protective cover 6 is buckled on the outside of the support block 5 and slides therewith, which is convenient for increasing the support effect on the inspection well wall and protecting the support block 5 and the sliding assembly. At the same time, it is also convenient to extend along with the adjustment of the support rod 4, and make its extension more uniform, avoiding damage caused by excessive protrusion on one side or affecting the difficulty of adjustment.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the sliding assembly includes a first ball 7 and a second ball 8. The first ball 7 is evenly mounted on the top of the support block 5 and is free to rotate, and the second ball 8 is mounted on the protruding front and rear side walls of the support block 5 and is free to rotate, so that when the sliding support rod 4 adjusts the protection size, the support block 5 slides in the protective cover 6, thereby driving the protective cover 6 to extend evenly, which makes the adjustment easy and convenient, and also helps to reduce the wear on the protective cover 6;

[0026] The first ball 7 and the second ball 8 can be replaced by rollers to facilitate the flexible rotation of the support block 5 in the protective sleeve 6 .

[0027] The adjusting component includes a disc 3, a through hole for passing the cylinder 1 is provided at the center of the disc 3, and a bearing 2 is installed in the through hole, the outer ring of the bearing 2 is fixed to the through hole wall, and the inner ring is fixed to the cylinder 1, a through groove is provided on the front side wall of the fixed tube 9, and a guide rod 10 is independently installed in the through groove, one end of the guide rod 10 is fixed to the front side wall of the support rod 4 in the fixed tube 9, and the other end is located outside the through groove, and a plurality of arc-shaped through grooves for the guide rod 10 to pass through are provided on the front side wall of the disc 3, when the disc 3 rotates, the support rod 4 is driven to slide in the fixed tube 9, so that the support rod 4 is driven to slide at the same time by the rotation of the disc 3, thereby changing the protection size to make it more applicable and have a better protection effect;

[0028] The cylinder 1 located outside the disc 3 is provided with a locking nut for fixing the disc 3 on the cylinder 1, so that the position of the disc 3 can be fixed after the length of the support rod 4 is adjusted by rotating the disc 3, so as to avoid the disc 3 being displaced and causing the support block 5 to fall off from the inspection well, thereby affecting the protection effect;

[0029] The front side wall of the disc 3 may also be provided with a hand crank to facilitate the rotation of the disc 3, thereby facilitating the adjustment of the support length, protection size and effect of the support rod 4;

[0030] The locking nut is threadedly matched with the cylinder 1. In order to improve the locking effect, a double nut can also be used, and the thread directions of the two nuts are opposite.

[0031] Example 2

[0032] This embodiment further illustrates the technology. Figure 5 As shown, a filter is provided on the front side of the disc 3, and a screw threadedly matched with the filter is provided on the cylinder 1 between the filter and the disc 3, and the movable end of the screw is a spherical structure, and a hook for installing the filter is provided on the outer wall of the protective sleeve 6, so that after the support rod 4 and the support block 5 are fitted with the inspection well to form a support, the garbage can be blocked by the filter, which can not only avoid injuries to personnel working in the inspection well, but also prevent excessive garbage from entering and affecting the construction progress.

[0033] A gap for placing the manhole cover is reserved between the bottom of the protective sleeve 6 and the bottom of the support rod 4, so as to protect the manhole cover and the inspection well at the same time after the manhole cover is installed.

[0034] Working principle: first rotate the disc 3 according to the size of the inspection well to adjust the support range of the support block 5. When the disc 3 is rotated, the support rod 4 is driven to move outward in the fixed tube 9. During the outward movement of the support rod 4, the protective cover 6 is propped up outward until it contacts the wall of the inspection well. In the process, the support block 5 is driven to rotate, so that the protective cover 6 is expanded more evenly. After the adjustment is completed, the position of the disc 3 is fixed by the locking nut, and finally the filter can be installed.
