[0029] A support mechanism 7 is provided on the top of the connecting claw 6 to automatically increase the support area and adapt to the support area when in use;

[0030] Furthermore, the support mechanism 7 includes a supporting plate 701, and both ends of the supporting plate 701 are provided with a second sliding groove 702, the inner wall of the second sliding groove 702 is slidably connected to a sliding plate 703, and the side wall of the sliding plate 703 is fixedly connected to a third spring 704, and the end of the third spring 704 away from the sliding plate 703 is fixedly connected to the inner wall of the second sliding groove 702, and the interior of the sliding plate 703 is fixedly connected with a pull rod 705, and both ends of the supporting plate 701 are hinged with an extension plate 706 through a torsion spring, and the end of the extension plate 706 close to the supporting plate 701 is provided with a third sliding groove 707, and the bottom of the extension plate 706 is provided with a card slot 708, and the interior of the supporting plate 701 is provided with a mounting plate 706. The mounting groove 709 is fixedly connected to a guide rod 710 on the inner wall of the mounting groove 709, a sliding block 711 is slidably connected to the outer wall of the guide rod 710, and a fourth spring 712 is fixedly connected to the top of the sliding block 711, and the end of the fourth spring 712 away from the sliding block 711 is fixedly connected to the inner wall of the mounting groove 709, and an extrusion column 713 is slidably connected to the inner wall of the mounting groove 709, and one end of the extrusion column 713 is fixedly connected to a U-shaped frame 714, and both ends of the U-shaped frame 714 are fixedly connected to a sliding rod 715, and an oblique groove 716 is opened on the side wall of the sliding block 711 facing the sliding rod 715, and the end of the sliding rod 715 away from the U-shaped frame 714 is slidably connected to the inner wall of the oblique groove 716;

[0031] More specifically, when the device is needed for support, the device is first placed below the area that needs support, and then the mounting base 18 is fixed to the ground to limit the position of the device. The knob 16 on either side is then manually turned, and the rotation of the knob 16 will drive the worm 15 to rotate synchronously. Since the inner wall of the gear teeth of the worm wheel 13 matches and meshes with the inner wall of the gear teeth of the worm 15, the worm 15 will drive the worm wheel 13 to rotate synchronously. Since the worm wheel 13 is a two-way thread design, the support frame 1 slides upward along the outer wall of the connecting block 17, and the lifting block 2 slides upward along the inner wall of the support frame 1, thereby increasing the height of the device. When the lifting block 2 slides upward, the supporting mechanism 7 is synchronously driven to move through the telescopic sleeve 3, the ball 4 and the connecting claw 6.

[0032] When the support mechanism 7 moves, the expansion plate 706 will slide along the inner wall of the support frame 1. During this process, the inclined surface of the end of the block 11 located inside the slot 708 will be squeezed by the inner wall of the slot 708, and then it will slide toward the inside of the support frame 1. At the same time, the second spring 12 will be compressed. Later, when the block 11 is out of contact with the slot 708, the block 11 no longer limits the expansion plate 706. Then the elastic force of the first spring 5 will be released, and then the released elastic force will drive the ball 4 and the connecting claw 6 to move upward, and then the connecting claw 6 will drive the load The plate 701 moves upward synchronously, and the supporting plate 701 drives the ends of the two extension plates 706 to move synchronously. Then, the extension plates 706 will leave the interior of the lifting block 2. At this time, the extension plates 706 are no longer limited. Then, the torsion force of the torsion spring drives the extension plates 706 to flip quickly. After that, when the extension plates 706 flip to the specified position, the ends of the extension plates 706 will contact the ends of the extrusion columns 713, and then squeeze them. After that, the extension plates 706 will flip over. At this time, the top height of the extension plates 706 is consistent with the top height of the supporting plate 701.

[0033] When the locking cam 711 is unlocked, the locking cam 711 is unlocked and the locking cam 711 is unlocked, so that the locking cam 711 is unlocked and the winch 7 is unlocked.

[0034] After the expansion plate 706 is flipped over, the third sliding groove 707 will correspond to the second sliding groove 702, so the third spring 704 will drive the sliding plate 703 to slide to the inner wall of the third sliding groove 707. At this time, half of the sliding plate 703 is inside the second sliding groove 702, and the other half is inside the third sliding groove 707, thereby achieving the connection and fixation between the supporting plate 701 and the expansion plate 706. After that, the lifting block 2 gradually rises, so that the supporting plate 701 or the expansion plate 706 will contact the supporting area of the building, and then the top of the supporting plate 701 and the expansion plate 706 will be attached to its surface, and then the telescopic sleeve 3 will be gradually re-compressed. After that, when the supporting plate 701 is re-attached to the top of the lifting block 2, the support installation work is completed;

[0035] When the support area of the building is designed to be inclined, the ball 4 is rotated inside the connecting claw 6, so that the support plate 701 can be flipped at an angle to match the inclination angle of the support area, thereby improving the versatility of the device in different environments. By clamping the two expansion plates 706 at both ends of the support plate 701, the folded expansion plate 706 can be automatically flipped to expand the support area when support is needed.

[0036] For example 2, please refer to Figures 1-6On the basis of the first embodiment, in this embodiment, the locking mechanism 9 includes an extrusion rod 901, and an L-shaped rod 902 is fixedly connected to the top of the extrusion rod 901, a second through-slot 903 is formed through the side wall of the extrusion rod 901, and a fixing rod 904 is slidably connected to the inner wall of the second through-slot 903, a fifth spring 905 is fixedly connected to the top of the fixing rod 904, and an end of the fifth spring 905 away from the fixing rod 904 is fixedly connected to the inner wall of the second through-slot 903, an extrusion plate 906 is slidably connected to the outer wall of the fixing rod 904, and an oblique groove 907 is formed on the side of the extrusion plate 906 facing the extrusion rod 901;

[0037] Furthermore, the outer wall of the extrusion rod 901 is slidably connected to the inner wall of the first through groove 8, the outer wall of the extrusion plate 906 is slidably connected to the inner wall of the first slide groove 10, the inner wall of the oblique groove 907 slides in contact with the side wall of the extrusion rod 901, and the side of the extrusion plate 906 away from the extrusion rod 901 corresponds to the inner wall of the support frame 1;

[0038] More specifically, when the device is supporting the installation work, the top of the supporting plate 701 and the expansion plate 706 will be pressed against the supporting area, which will compress the telescopic sleeve 3. Then, when the supporting plate 701 moves toward the lifting block 2, the pull rod 705 will be displaced synchronously during the process. Then, the outer wall of the pull rod 705 will contact the top of the L-shaped rod 902 and squeeze it. Then, after the L-shaped rod 902 is squeezed, it will drive the squeezing rod 901 to slide downward along the inner wall of the first through groove 8. Then, the supporting plate 701 and the expansion plate 706 will be pressed together. 06 completes the supporting state, at this time stop turning the knob 16, because the worm wheel 13 and the worm 15 have a self-locking property, they can maintain the supporting state, and when the extrusion rod 901 slides downward, its side wall will squeeze the inner wall of the oblique groove 907, so that the extrusion plate 906 will slide along the inner wall of the fixed rod 904 after being squeezed, and then the side wall of the extrusion plate 906 will slide out of the inner wall of the first sliding groove 10, and then its side wall will be squeezed on the inner wall of the support frame 1, thereby realizing the automatic locking of the lifting block 2 in the internal position of the support frame 1;

[0039] The stable self-locking property of the worm gear 13 and the worm 15 ensures that the position and posture of the supported object remain unchanged. At the same time, the extrusion plate 906 is pressed against the inner wall of the support frame 1 to replace the locking of the lifting block 2 by the worm gear 13 and the worm 15, eliminating the hidden danger of damage to the bidirectional screw 14 under high-intensity pressure and avoiding damage to the device.

[0040] When the device is finished using, the pull rod 705 is pulled out of the top of the L-shaped rod 902, and then the L-shaped rod 902 will be subjected to the elastic force of the extrusion rod 901 and will slide upward along the inner wall of the first through-slot 8. Then the extrusion plate 906 will no longer be squeezed on the inner wall of the support frame 1, thereby contacting the extrusion plate 906 to lock the position of the lifting block 2. At the same time, during the movement of the fifth spring 905, the second through-slot 903 will be driven out of the inside of the third sliding groove 707. Then the guide rod 710 will drive the sliding block 711 to slide downward, and the sliding block 711 will slide into the top groove of the guide rod 710, and the sliding plate 703 will be re-positioned, thereby completing the dismantling of the device.

[0041] The working principle of the present invention is as follows: first, the device is placed below the area to be supported, and then the mounting base 18 is fixed to the ground to limit the position of the device. Then, the knob 16 on either side is manually turned, and the rotation of the knob 16 drives the worm 15 to rotate synchronously. Since the inner wall of the gear teeth of the worm wheel 13 matches and meshes with the inner wall of the gear teeth of the worm 15, the worm 15 drives the worm wheel 13 to rotate synchronously. Since the worm wheel 13 is a bidirectional thread design, the support frame 1 slides upward along the outer wall of the connecting block 17, and the lifting block 2 slides upward along the inner wall of the support frame 1, thereby increasing the height of the device.

[0042] When the support mechanism 7 moves, the expansion plate 706 will slide along the inner wall of the support frame 1. During this process, the inclined surface of the end of the block 11 located inside the slot 708 will be squeezed by the inner wall of the slot 708, and then it will slide toward the inside of the support frame 1. At the same time, the second spring 12 will be compressed. Later, when the block 11 is out of contact with the slot 708, the block 11 no longer limits the expansion plate 706. Then the elastic force of the first spring 5 will be released, and then the released elastic force will drive the ball 4 and the connecting claw 6 to move upward, and then the connecting claw 6 will drive the load The plate 701 moves upward synchronously, and the supporting plate 701 drives the ends of the two extension plates 706 to move synchronously. Then, the extension plates 706 will leave the interior of the lifting block 2. At this time, the extension plates 706 are no longer limited. Then, the torsion force of the torsion spring drives the extension plates 706 to flip quickly. After that, when the extension plates 706 flip to the specified position, the ends of the extension plates 706 will contact the ends of the extrusion columns 713, and then squeeze them. After that, the extension plates 706 will flip over. At this time, the top height of the extension plates 706 is consistent with the top height of the supporting plate 701.

[0043] After the expansion plate 706 is flipped over, the third slide groove 707 will correspond to the second slide groove 702, so the third spring 704 will drive the sliding plate 703 to slide to the inner wall of the third slide groove 707. At this time, half of the sliding plate 703 is inside the second slide groove 702, and the other half is inside the third slide groove 707, thereby realizing the connection and fixation between the supporting plate 701 and the expansion plate 706. After that, during the gradual rise of the lifting block 2, the supporting plate 701 or the expansion plate 706 will contact the supporting area of the building, and then the top of the supporting plate 701 and the expansion plate 706 will be attached to its surface, and then the telescopic sleeve 3 will be gradually re-compressed, and then when the supporting plate 701 is re-attached to the top of the lifting block 2, the support installation work is completed.

[0044] It should be noted that the various devices in this application are common devices in the market, and can be selected according to specific needs during specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection part. Those skilled in the art can implement it relatively easily. It belongs to the existing technology and will not be elaborated on.

[0045] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
