The left clamping rod 2 is vertically connected to the left cross brace rod 4, and the right clamping rod 3 is vertically connected to the right cross brace rod 5. The left cross brace rod 4 and the right cross brace rod 5 are inserted into the rod sleeve 7 and move left and right along the rod sleeve 7. The left cross brace rod 4 and the right cross brace rod 5 are connected by a connecting spring 6, which pulls the left clamping rod 2 and the right clamping rod 3 to open the spring, thereby realizing the fastening of the left clamping rod 2 and the right clamping rod 3 to the supporting rod 1.
[0022] The leaning rod 1 is arranged on the left and right sides of the plastered wall end. The leaning rod 1 can be any straight rectangular material, such as square wood, template sheet, and scraper bar used for plastering. The leaning rod 1 fits with the left and right sides of the plastered wall end.
[0023] The left clamping rod 2 is arranged at the left end of the left cross brace 4, extends downward from the cross section of the left cross brace 4 to fasten the leaning rod 1, so that the leaning rod 1 is in close contact with the end of the plastered wall, and the left clamping rod 2 and the left cross brace 4 form an L-shaped structure; the right clamping rod 3 is arranged at the right end of the right cross brace 5, extends downward from the cross section of the right cross brace 5 to fasten the leaning rod 1, so that the leaning rod 1 is in close contact with the end of the plastered wall, and the right clamping rod 3 and the right cross brace 5 form an L-shaped structure; the left clamping rod 2, the left cross brace 4, the right clamping rod 3, the right cross brace 5 and the tube rod sleeve 7 form a door shape with an opening at the bottom.
[0024] The left cross brace rod 4 is arranged on the left side of the cylinder rod sleeve 7, and the right end of the left cross brace rod 4 is provided with an anti-detachment clamp 8 to prevent the left cross brace rod 4 from detaching from the cylinder rod sleeve 7 when moving back and forth. The right end of the left cross brace rod 4 is connected to the left end of the connecting spring 6, and the right cross brace rod 5 is arranged on the right side of the cylinder rod sleeve 7. Fixed clamps 9 are provided on both sides of the left end of the right cross brace rod 5, and the left end of the right cross brace rod 5 is fixedly connected to the cylinder rod sleeve 7 through the fixed clamps 9.
[0025] The connecting spring 6 is disposed in the barrel sleeve 7 , and the connecting spring extends in the left-right direction of 6 .
[0026] The left clamping rod 2, the left cross bracing rod 4, the right clamping rod 3, the right cross bracing rod 5 and the rod sleeve 7 are all square rods.
[0027] The cross brace has a cross section size of 30mm*30mm*2mm and is made of aluminum alloy. The cross brace is divided into a left cross brace 4 and a right cross brace 5. The left cross brace 4 has a total length of 90mm and its left end is integrated with the left clamping rod 2; 1mm protruding anti-dropping clips 8 are left on both sides of the right end, and the end is connected to the right cross brace 5 through a connecting spring 6. The right cross brace 5 has a total length of 90mm and its right end is integrated with the right clamping rod; the left end is connected to the barrel sleeve 7 through a fixing clip 9 on both sides, and the end is connected to the left cross brace 4 through a connecting spring 6.

[0029] The connecting spring 6 is a spring with a static length of 60 mm. Considering the fastening requirements of the left clamping rod 2 and the right clamping rod 3 and the normal pulling force of human hands, the elastic coefficient K of the connecting spring 6 is tentatively required to be 15-20 N / cm.
[0030] The inner size of the rod sleeve 7 is a 34mm*34mm aluminum alloy square tube with a wall thickness of 1mm, which is connected to the right cross brace 5 through a fixed clamp 9, and a 1mm anti-slip protrusion is left at the left end opening of the rod sleeve 7. The rod sleeve 7 (which can accommodate the spring stretch length) can be adjusted to 80mm in length.
[0031] A construction method of a door and window opening plastering and closing fixture:
[0032] 1. Before use, take two supporting rods 1 and stick them on both sides of the wall to be closed and plastered. The supporting rods 1 can be any straight rectangular material, such as square wood, template sheet, or scraper bar used for plastering.
[0033] 2. Use both hands to pull the left clamp rod 2 and the right clamp rod 3 to open the connecting spring 6, so that the left clamp rod 2 and the right clamp rod 3 are clamped against the rod 1. Use two such clamps on each side of the hole to ensure that the upper and lower clamps are secure. If the hole size is very large, more clamps can be added as needed.
