[0022] Insert a push rod 42 of corresponding length (according to the vertical distance between the mounting seat 41 and the template 1) into the mounting seat 41, and then drive the push rod 42 to extend. The push rod 42 pushes the support block 43 to move upward, and the support block 43 pushes the pallet 44 and the anti-slip pad 45 to follow the movement. The anti-slip pad 45 contacts the template 1 and pushes the pallet 44 to rotate on the support plate 43. The angle is adjusted to facilitate fitting with the template 1. When adjusting the angle, the torsion spring is subjected to force, and the pallet 44 supports the template 1, so that the pallet 44 can adapt to the angle of the template 1, thereby facilitating the pallet 44 to support the template 1.

[0023] An adjusting device 3 is provided on the base plate 2, and the adjusting device 3 is used to longitudinally adjust the position of the supporting device 4. The adjusting device 3 includes a sliding frame 31 slidably clamped on the base plate 2, and the sliding frame 31 limits separation from the base plate 2.

The width of the anti-skid plate 33 is less than or equal to the width of the sliding frame 31.

[0024] Before inserting the push rod 42 into the mounting seat 41, the sliding frame 31 is pushed to move according to the support point of the template 1. The movement of the sliding frame 31 causes the mounting seat 41 to follow the longitudinal movement, and the base plate 2 is moved to cause the mounting seat 41 to follow the movement. When the mounting seat 41 moves to just below the support point, the movement of the sliding frame 31 is stopped, the base plate 2 is fixed on the base plate, and then the screw 32 is rotated. The screw 32 is threadedly connected to the sliding frame 31 and pushes the anti-skid plate 33 to squeeze and contact the base plate 2, thereby limiting the movement of the sliding frame 31, so that the supporting position of the support plate 44 can be adjusted, thereby improving the supporting effect.

[0025] Working principle: The utility model inserts a push rod 42 of a corresponding length (according to the vertical distance between the mounting seat 41 and the template 1) into the mounting seat 41, and then drives the push rod 42 to extend, and the push rod 42 pushes the support block 43 to move upward, and the support block 43 pushes the support plate 44 and the anti-skid pad 45 to follow the movement, and the anti-skid pad 45 contacts the template 1, pushing the support plate 44 to rotate on the support plate 43, and adjusting the angle is convenient for fitting with the template 1. When adjusting the angle, the torsion spring is stressed, and the support plate 44 supports the template 1, so that the support plate 44 can adapt to the angle of the template 1, thereby facilitating the support plate 44 to fit the template 1. The template 1 is supported, and the push rod 42 is inserted into the front of the mounting seat 41. According to the support point of the template 1, the sliding frame 31 is pushed to move. The movement of the sliding frame 31 makes the mounting seat 41 follow the longitudinal movement, and the base plate 2 is moved to make the mounting seat 41 follow the movement. When the mounting seat 41 moves to just below the support point, the movement of the sliding frame 31 is stopped, and the base plate 2 is fixed on the base plate, and then the screw 32 is rotated. The screw 32 is threadedly connected to the sliding frame 31 to push the anti-skid plate 33 to squeeze and contact the base plate 2, thereby limiting the movement of the sliding frame 31, so that the supporting position of the support plate 44 can be adjusted, thereby improving the supporting effect.
