[0030] The inner wall of the sleeve rod 11 is slidably connected to the outer wall of the rod body 10, the first sliding groove 14 is opened on the inner wall of the cross bar 13, one side of the first slider 15 is slidably connected to the inside of the first sliding groove 14, and the other side of the first slider 15 is fixedly connected to one side of the first adjusting rod 16.

[0031] In one embodiment, the outer wall of the first fixing bolt 12 is threadedly connected to the inside of the sleeve rod 11, and the outer wall of the second fixing bolt 17 is threadedly connected to the inside of the cross bar 13. The first fixing bolt 12 is loosened and the sleeve rod 11 is pulled so that the rod body 10 can be pulled out from the inside of the sleeve rod 11. The second fixing bolt 17 is loosened and the cross bar 13 is pulled so that the first adjustment rod 16 is pulled out from the cross bar 13. After adjusting to the appropriate size, the first fixing bolt 12 and the second fixing bolt 17 are tightened to fix the sleeve rod 11 and the first adjustment rod 16. In summary, the utility model can adjust the width, so that it is suitable for foundation pits of different sizes, which increases the scope of application of the device. Through the setting of the first slide groove 14 and the first slider 15, the first adjustment rod 16 is accurately guided to avoid the displacement of the moving position of the first adjustment rod 16.

[0032] In one embodiment, the two height adjustment components 201 include a vertical pole 20, a second sliding groove 21, a second slider 22, a second adjusting rod 23 and a third fixing bolt 24; the top of the rod body 10 and the sleeve rod 11 are fixedly connected to the bottom of the vertical pole 20, the second adjusting rod 23 and one side of the vertical pole 20 are fixedly connected to one side of the cross bar 13, the second adjusting rod 23 and one side of the vertical pole 20 are fixedly connected to one side of the first adjusting rod 16, the second sliding groove 21 is opened on the inner side wall of the vertical pole 20, one side of the second slider 22 is slidably connected to the inside of the second sliding groove 21, and the other side of the second slider 22 is fixedly connected to one side of the second adjusting rod 23, and the outer side wall of the third fixing bolt 24 is threadedly connected to the inside of the vertical pole 20. By loosening the third fixing bolt 24, the second adjusting rod 23 is pulled out from the vertical pole 20 and adjusted to a specified height. By tightening the third fixing bolt 24, the position of the second adjusting rod 23 is fixed, thereby realizing the height adjustment function of the utility model.

[0033] The third slide 30 is provided on one side of the sleeve rod 11, and one side of the third slide 31 is slidably connected to the inside of the third slide 30, and the outer wall of the fourth fixing bolt 32 is threadedly connected to the inside of the third slide 31.

Through the setting of the connecting block 41, the two adjacent vertical poles 20 can be spliced ​​together, and the pin shaft can be inserted to complete the splicing between the two protective devices, which is convenient and quick.

[0035] When the present invention is in operation, the staff pushes the device to the designated position, then locks the wheel brake of the universal wheel 40, loosens the fourth fixing bolt 32, so that the fourth fixing bolt 32 releases the third slider 31, manually presses the third slider 31, and the third slider drives the mounting plate 33 to move in the third slide groove 30, so that the bottom of the mounting plate 33 is close to the ground, and then tightens the fourth fixing bolt 32, so that the fourth fixing bolt 32 fixes the third slider 31, and then inserts the bolt into the mounting hole 34, so that the mounting plate 33 is fixed to the ground by the bolt, thereby increasing the grip of the device. After the fixing is completed, the adjacent vertical poles 20 are connected by the connecting block 41 as needed, and then the pin is inserted into the interior of the connecting block 41, thereby completing the splicing between the two protective devices. When adjusting the height, the third fixing bolt 24 is loosened and the second adjusting rod 23 is pulled so that the second adjusting rod 23 is pulled out from the vertical rod 20 and adjusted to the specified height. Then, the third fixing bolt 24 is tightened to fix the position of the second adjusting rod 23, thereby realizing the height adjustment function of the device. When width adjustment is required, the first fixing bolt 12 and the second fixing bolt 17 are loosened and the sleeve rod 11 is pulled so that the rod body 10 can be pulled out from the inside of the sleeve rod 11. At the same time, the first adjusting rod 16 is pulled out from the cross bar 13. After the width is adjusted to the appropriate size, the first fixing bolt 12 and the second fixing bolt 17 are tightened to fix the positions of the sleeve rod 11 and the first adjusting rod 16. In summary, the utility model can adjust the width, so that it is suitable for foundation pits of different sizes, which increases the scope of application of the device.
