[0028] When installing and using the fixed bracket, the angles of the two support plates are adjusted according to the angles at the bends of the template. During the adjustment, the first support plate 2 is attached to the corresponding template, the fixed bracket is moved to the bend of the template, and the second support plate 3 is rotated to attach to the template on the other side. In this process, the driving assembly 9 is used to drive the arc rack 7 so that the arc rack 7 moves in the fixed guide assembly 8, and the rotating seat 5 at the end of the second support plate 3 is rotated on the rotating block 4 through the rotating shaft 6, so as to achieve the purpose of angle adjustment. After the adjustment is completed, the fixed guide assembly 8 is operated to ensure that the arc rack 7 is fixed, and then the bottom plate 1 is installed to the ground using the mounting holes 11 in conjunction with the ground nails. After the entire fixed bracket is installed, the first support plate 2 and the second support plate 3 play a role of fixed support for the template. If the template height is high, the lifting support assembly 10 can also be adjusted to move it in the storage slot 12 until the height of the lifting support assembly 10 is appropriate, and then the lifting support assembly 10 is operated accordingly to support the upper part of the template.

[0029] According to the above embodiment, the fixed guide assembly 8 includes a fixed guide seat 801, a guide groove 802 and a locking bolt 803, the guide groove 802 is opened on the fixed guide seat 801, and the fixed guide seat 801 is fixed on the bottom plate 1, the locking bolt 803 is threadedly connected to the fixed guide seat 801, and the end of the locking bolt 803 is located in the guide groove 802, and the driving assembly 9 includes a rotating seat 901, a rotating rod 902, a plug-in shaft 903, a connecting protrusion 904, a threaded rod 905, hexagonal block 906, gear 907, round hole 908, keyway 909, stop plate 910, threaded hole 911, adjusting wheel 912 and hexagonal hole 913, rotating rod 902 is rotatably connected to rotating seat 901, and rotating seat 901 is fixed on bottom plate 1, plug shaft 903 is arranged on rotating rod 902, connecting protrusion 904 is fixed on plug shaft 903, round hole 908 and keyway 909 are provided on gear 907, and gear 907 is sleeved through round hole 908 The connecting protrusion 904 is clamped in the keyway 909, the threaded rod 905 is fixedly connected with the hexagonal block 906, and the threaded rod 905 is arranged at the upper end of the connecting shaft 903, the threaded hole 911 is arranged on the limit plate 910, and the limit plate 910 is connected to the threaded rod 905 through the threaded hole 911, the limit plate 910 abuts against the gear 907, the hexagonal hole 913 is arranged on the adjusting wheel 912, and the adjusting wheel 912 is connected to the hexagonal hole 913. On the corner block 906, the driving component 9 is used to drive the arc rack 7 to ensure the driving effect. When used in conjunction with the fixed guide component 8, the stability after adjustment can be guaranteed. The gear 907 is set on the plug-in shaft 903 and is fixed by a threaded limit plate 910. The gear 907 can be quickly installed and removed. The adjusting wheel 912 is installed on the hexagonal block 906. After connection, it has high stability and can be quickly removed to remove the gear 907.

[0030] When assembling the fixed guide assembly 8 and the driving assembly 9, the fixed guide seat 801 is fixed to the bottom plate 1, the guide groove 802 is adapted to the arc-shaped rack 7, the locking bolt 803 is installed on the fixed guide seat 801, the lower end of the rotating rod 902 is rotatably connected to the rotating seat 901, the gear 907 is sleeved on the plug-in shaft 903 through the circular hole 908, and the connecting protrusion 904 is ensured to be snapped into the keyway 909, thereby completing the installation of the gear 907, and then the limit plate 910 is rotatably installed on the threaded rod 905 using the threaded hole 911. The limiting plate 910 is in contact with the gear 907. At this time, under the joint action of the rotating rod 902 and the limiting plate 910, the gear 907 is fixedly arranged on the plug-in shaft 903, and the gear 907 is meshed and connected with the arc-shaped rack 7. Finally, the adjusting wheel 912 is installed on the hexagonal block 906 using the hexagonal hole 913. After the fixed guide assembly 8 and the driving assembly 9 are installed, they are put into use. When the angle of the second support plate 3 and the first support plate 2 is adjusted, the hexagonal block 906 is rotated by the adjusting wheel 912, and the hexagonal block 906 is driven down by the threaded rod 905. The rotating rod 902 at the end rotates on the rotating seat 901, thereby rotating the gear 907 through the plug-in shaft 903 and the connecting protrusion 904. Driven by the gear 907, the arc-shaped rack 7 is forced to rotate along the rotating shaft 6 with the second support plate 3 until the second support plate 3 fits the template in the corresponding direction. During this process, the arc-shaped rack 7 moves in the guide groove 802 on the fixed guide seat 801. When the adjustment is completed, the locking bolt 803 is rotated with a tool so that the end of the locking bolt 803 abuts against the arc-shaped rack 7, thereby adjusting the arc-shaped rack. 7 is fixed to ensure that the second support plate 3 has good stability after adjustment. During the entire adjustment process, the angle between the first support plate 2 and the second support plate 3 is between 90 degrees and 180 degrees. The use flexibility and adaptability are high. When necessary, the gear 907 can be quickly replaced. When replacing, first remove the adjusting wheel 912 on the hexagonal block 906, then rotate the limit plate 910, remove the limit plate 910 from the threaded rod 905, and finally move the gear 907 upward for disassembly. The structure is simple and the operation is convenient and quick.

[0031] According to the above implementation scheme, the lifting support assembly 10 includes a lifting plate 1001, a spring 1002, an adjusting screw 1003, a limit block 1004 and a supporting bolt 1005. The lower end of the lifting plate 1001 is inserted into the receiving groove 12, the spring 1002 is located at the bottom of the receiving groove 12, and the upper end of the spring 1002 is in contact with the lifting plate 1001. A through hole is provided on the lifting plate 1001, the adjusting screw 1003 is fixedly connected to the limit block 1004, and the adjusting screw 1003 passes through the through hole on the lifting plate 1001. The lower end is connected to the adjusting screw hole 14, and the support bolt 1005 is threadedly connected to the lifting plate 1001. Through the setting of the lifting support assembly 10, the height can be adjusted along the support plate, which is suitable for templates of different heights. The lifting support assembly 10 is provided with a spring 1002 and an adjusting screw 1003. The spring 1002 applies a force to the lifting plate 1001, so that the lifting plate 1001 has a tendency to move upward. When used in conjunction with the adjusting screw 1003 and the adjusting screw hole 14, the height of the lifting plate 1001 can be adjusted, thereby improving the flexibility of use.

[0032] When setting the lifting support assembly 10, the upper end of the spring 1002 is connected to the lower end of the lifting plate 1001, and the lower end of the lifting plate 1001 and the spring 1002 are set in the storage groove 12. Under the action of gravity and the spring 1002, the lifting plate 1001 is in an expanded state, and then the adjusting screw 1003 with the limit block 1004 is passed through the through hole on the lifting plate 1001, and the adjusting screw 1003 is rotated so that the lower end of the adjusting screw 1003 is screwed into the adjusting screw hole 14. As the adjusting screw 1003 continues to rotate, the adjusting screw 1003 descends with the limit block 1004, thereby bringing the lifting plate 1001 down for storage, and the spring 1002 is compressed. Then a supporting bolt 1005 is set on the lifting plate 1001, and the supporting bolt 1005 is located in the U-shaped hole 13. When using a fixed bracket, if the template height is relatively low, directly use the first support plate 2 and the second support plate 1005 to adjust the height of the lifting plate 1001. The second support plate 3 supports the template. At this time, most of the lifting plate 1001 in the lifting support assembly 10 is in a state of being stored in the storage groove 12. When the height of the template is high, the adjusting screw 1003 is rotated through the limit block 1004, and the adjusting screw 1003 rotates and rises in the adjusting screw hole 14, and the limit block 1004 moves up synchronously. Under the action of the spring 1002, the lifting plate 1001 rises together until the lifting plate 1001 rises to a suitable height. In this process, the supporting bolt 1005 moves along the U-shaped hole 13. When the lifting plate 1001 is unfolded, the supporting bolt 1005 is rotated so that the end of the supporting bolt 1005 passes through the lifting plate 1001 and abuts against the template, thereby supporting the upper part of the template and ensuring the fixed support effect of the template. After use, the adjusting screw 1003 is rotated to perform the storage rack of the lifting plate 1001.
