[0029] Reference Figure 2-4The base 1 is provided with an adjustment structure 4, which is mainly composed of four adjustment slots 41. The four adjustment slots 41 are respectively opened on the four support columns 2. The adjustment slots 41 are slidably connected with adjustment columns 42. The base 1 is placed under the template, and the four adjustment columns 42 are slid upward so that the top of the four adjustment columns 42 supports the template body 3, thereby avoiding the situation that the height of the cantilevered template is not necessarily the same each time, so it is necessary to select stakes of different lengths or combine scaffolds of different heights each time, which leads to cumbersome support operations. The inner wall of the adjustment slot 41 is rotatably connected with a thread Rod 43, threaded rod 43 is threadedly inserted on adjusting column 42, because adjusting column 42 is limited and slidable in adjusting groove 41, the height of adjusting column 42 can be adjusted by rotating threaded rod 43, and threaded rod 43 can limit adjusting column 42, one end of threaded rod 43 is fixedly connected with first bevel gear 44, second bevel gear 45 is meshedly connected with first bevel gear 44, connecting column 46 is fixedly connected with second bevel gear 45, one support column 2 is fixedly connected with equipment plate 47, first motor 48 is fixedly connected with equipment plate 47, output shaft of first motor 48 is fixedly connected with connecting column 46 Then, the two connecting columns 46 on one side are fixedly connected with pulleys 49, and the two pulleys 49 are jointly provided with a transmission belt 410. The first motor 48 is started, and the output shaft of the first motor 48 drives a pulley 49 to rotate. Under the action of the transmission belt 410, the two pulleys 49 rotate synchronously, thereby driving the two connecting columns 46 on one side to rotate synchronously, thereby making the two threaded rods 43 on one side rotate synchronously, making the operation more convenient. The two second bevel gears 45 on one side are respectively fixedly connected with outer rods 411, and the two second bevel gears 45 on the other side are respectively fixedly connected with outer rods 412. 5 are respectively fixedly connected with inner rods 412, the outer rod 411 is slidably connected to the inner rod 412, the outer rod 411 is fixedly connected with two limit blocks 414, the inner rod 412 is provided with two limit grooves 413, the limit grooves 413 are slidably connected with the limit blocks 414, under the action of the outer rod 411 and the inner rod 412, the two second bevel gears 45 on the left rotate synchronously, which will drive the two second bevel gears 45 on the right to rotate, thereby making the four second bevel gears 45 rotate synchronously, and the limit blocks 414 limit and slide in the limit grooves 413 to prevent the outer rod 411 and the inner rod 412 from rotating.

[0030] Reference Figure 1 , Figure 2 and Figure 5, a mounting structure 5 is provided on the base 1, and the mounting structure 5 is mainly composed of two support plates 51, and the two support plates 51 are respectively fixedly connected to the two support columns 2 located on both sides, and two bolts 52 are fixedly connected to the template body 3, and two connecting holes 53 are provided on the support plate 51, and two nuts 54 are provided on the support plate 51. The bolts 52 are inserted into the corresponding connecting holes 53, and then the nuts 54 are screwed on the bolts 52. The support plate 51 can strengthen the supporting area of ​​the template body 3, thereby improving the supporting effect. Two slide grooves 55 are provided on the base 1, and the slide grooves 55 are slidably connected to the support columns 2. After the template body 3 and the support plates 51 are installed, sliding four support columns 2 can connect the two template bodies 3 together. A bidirectional screw 56 is rotatably connected in a slide groove 55, and the bidirectional screw 56 is threadedly connected to the two support columns 2. The two sections of the thread on the bidirectional screw 56 are in opposite directions. A second motor 57 is fixedly connected, and the output shaft of the second motor 57 is fixedly connected to the bidirectional screw 56. When the second motor 57 is started, the output shaft of the second motor 57 drives the bidirectional screw 56 to rotate. Since the support column 2 slides in the slide groove 55, rotating the bidirectional screw 56 can drive the support column 2 to slide. Since the two sections of the thread on the bidirectional screw 56 are in opposite directions, rotating the bidirectional screw 56 can make the two support columns 2 approach each other or move away from each other, making the operation more convenient.

A through hole larger than the outer rod 411 is opened on the oblique support 58, and the through hole does not contact the outer wall of the outer rod 411 and the inner rod 412.

[0031] Working principle: place the base 1 under the template, slide the four adjusting columns 42 upward, so that the top of the four adjusting columns 42 supports the template body 3, thereby avoiding the situation that the height of the cantilevered template is not necessarily the same each time, so it is necessary to select wooden stakes of different lengths or combine scaffolds of different heights each time, which leads to cumbersome support operation. Since the adjusting column 42 slides in the adjusting groove 41, the height of the adjusting column 42 can be adjusted by rotating the threaded rod 43, and the threaded rod 43 can limit the adjusting column 42. Start the first motor 48, and the output shaft of the first motor 48 drives a pulley 49 to rotate. Under the action of the transmission belt 410, the two pulleys 49 rotate synchronously, and then drive the two connecting columns 46 on one side to rotate synchronously, so that the two threaded rods 43 on one side rotate synchronously, making the operation more convenient. Under the action of the outer rod 411 and the inner rod 412, the synchronous rotation of the two second bevel gears 45 on the left will drive the two second bevel gears 45 on the right to rotate, so that the four second bevel gears 45 rotate synchronously. The outer rod 411 and the inner rod 412 are prevented from rotating by the limiting block 414 in the limiting groove 413. The bolt 52 is inserted into the corresponding connecting hole 53, and the nut 54 is screwed on the bolt 52. The support plate 51 can strengthen the supporting area of ​​the template body 3, thereby improving the supporting effect. After the template body 3 and the support plate 51 are installed, the four support columns 2 can be slid to connect the two template bodies 3 together, and the second motor 57 is started. The output shaft of the second motor 57 drives the bidirectional screw 56 to rotate. Since the support column 2 slides in the slide groove 55, rotating the bidirectional screw 56 can drive the support column 2 to slide. Since the two sections of the thread on the bidirectional screw 56 are in opposite directions, rotating the bidirectional screw 56 can make the two support columns 2 approach or move away from each other, making the operation more convenient. The diagonal support 58 can make the support more stable. During the movement of the support column 2, the support block 59 can slide along the slide rail 510. The diagonal support 58 is provided with a through hole larger than the outer rod 411, and the through hole does not contact the outer wall of the outer rod 411 and the inner rod 412.
