A first guide block 4 is fixedly connected to the front side of the first extension plate 2. The front side of the first guide block 4 extends into the interior of the second extension plate 3 and slides in connection with the inner wall of the second extension plate 3. A second guide block 5 is fixedly connected to the rear side of the second extension plate 3. The rear side of the second guide block 5 extends into the interior of the first extension plate 2 and slides in connection with the inner wall of the first extension plate 2. A first retaining sleeve 6 is fixedly connected to the surface of the first extension plate 2. The first retaining sleeve 6 is fitted onto the surface of the second extension plate 3 and slides in connection with the surface of the second extension plate 3. A second retaining sleeve 7 is fixedly connected to the surface of the second extension plate 3. The second retaining sleeve 7 is fitted onto the surface of the first extension plate 2 and slides in connection with the surface of the first extension plate 2.

[0020] refer to Figure 5 The bottom of the first sleeve 6 and the second sleeve 7 are both fixedly connected to the transmission box 8. The bottom of the transmission box 8 is provided with a rotating rod 9. The top of the rotating rod 9 extends into the interior of the transmission box 8 and is movably connected to a push plate 10 through a bearing. The surface of the push plate 10 is slidably connected to the inner wall of the transmission box 8. The surface of the rotating rod 9 is threadedly connected to the inner wall of the transmission box 8. The top of the push plate 10 is fixedly connected with multiple locking blocks 11. The bottom of the first extension plate 2 and the second extension plate 3 are both provided with multiple locking slots 12. The locking blocks 11 penetrate the transmission box 8 and extend into the interior of the locking slots 12 and contact the inner wall of the locking slots 12.

[0021] As a technical optimization of this utility model, by setting up a transmission box 8, a rotating rod 9, a push plate 10, a locking block 11, and a locking groove 12, the first extension plate 2 and the second extension plate 3 can be fixed, thus preventing the first extension plate 2 and the second extension plate 3 from moving randomly after the support width is adjusted.

[0022] refer to Figure 5 The bottom of the transmission box 8 is provided with a rotating block 13, and the top of the rotating block 13 is fixedly connected to the bottom of the rotating rod 9.

[0023] As a technical optimization of this utility model, by setting the rotating block 13, it is easier for the user to rotate the rotating rod 9, thereby improving the user's comfort.

[0024] refer to Figure 5 The surface of the rotating block 13 is provided with a rotating groove 14, which is used in conjunction with the rotating block 13.

[0025] As a technical optimization of this utility model, by setting the rotating groove 14, the user can better grip the rotating block 13 and avoid the phenomenon of slippage when the user directly rotates the rotating block 13.

[0026] refer to Figure 5Both sides of the push plate 10 are fixedly connected to sliders 15, and the outer side of the sliders 15 extends into the interior of the transmission box 8 and slides in connection with the inner wall of the transmission box 8.

[0027] As a technical optimization of this utility model, by setting the slider 15, the push plate 10 can be guided, thereby improving the stability of the push plate 10 during movement.

[0028] refer to Figure 5 The inner walls of the transmission box 8 are provided with grooves 16 on both sides, and the outer side of the slider 15 extends into the interior of the groove 16 and is slidably connected to the groove 16.

[0029] As a technical optimization of this utility model, by opening the slide groove 16, the slider 15 can be limited, thus preventing the slider 15 from getting stuck during movement.

[0030] refer to Figure 5 The surface of the rotating rod 9 is threaded with a guide sleeve 17, and the bottom of the guide sleeve 17 is fixedly connected to the bottom of the inner wall of the transmission box 8.

[0031] As a technical optimization of this utility model, by setting the guide sleeve 17, the rotating rod 9 can be guided, thus preventing the rotating rod 9 from shaking randomly when rotating.

[0032] refer to Figure 4 A friction pad 18 is fixedly connected to the top of the card block 11, and the surface of the friction pad 18 is in contact with the inner wall of the card slot 12.

[0033] As a technical optimization of this utility model, by setting the friction pad 18, the contact between the card block 11 and the card slot 12 can be made tighter, increasing the contact area between the card block 11 and the card slot 12.

[0034] The working principle and usage process of this utility model are as follows: First, place the support frame inside the tunnel, so that one side of the support 1 contacts the inner wall of the tunnel. After contact, rotate the rotating block 13. The rotating block 13 drives the rotating rod 9 to rotate. When the rotating rod 9 rotates, it drives the push plate 10 to move downwards. The push plate 10 drives the locking block 11 to move downwards, so that the locking block 11 moves away from the locking slot 12. After this, the user pulls the right side of the support 1 to the right. The support 1 drives the second extension plate 3 to move to the right. The second extension plate 3 drives the second guide block 5 to move to the right, so that the right side of the second guide block 5 contacts the inner wall of the other side of the tunnel. After contact, rotate the rotating block 13 in the opposite direction, so that the locking block 11 is locked back into the locking slot 12, fixing the extended support 1, the first extension plate 2, and the second extension plate 3. Finally, to remove the support, simply reverse the above operation.

[0035] In summary, this novel support device for steeply inclined thin orebody mining areas, by setting a first extension plate 2 and a second extension plate 3, allows for adjustment of the support width, preventing fixed support widths from being incompatible with tunnels of different widths. By setting a first guide block 4 and a second guide block 5, the first extension plate 2 and the second extension plate 3 are limited, preventing the first extension plate 2 from moving away from the second extension plate 3. By setting a transmission box 8, a rotating rod 9, a push plate 10, a locking block 11, and a locking groove 12, the first extension plate 2 and the second extension plate 3 are fixed, preventing movement after position adjustment. This device offers the advantage of easy adjustment and solves the problem that most existing support frames have fixed widths, which necessitates the use of different models of support frames when supporting tunnels of different widths, increasing user costs and reducing support frame performance.
