A lifting component 4 for unfolding the mesh cloth is provided between the base 1 and the frame 2, and a clamping component 5 for sticking the mesh cloth to the wall is provided between the base 1 and the frame 2.

[0034] Reference Figure 3The lifting assembly 4 includes a servo motor 41, a screw rod 42, a nut 43, a second connecting rod 44 and a third connecting rod 45. Servo motors 41 are provided on both sides of the top of the base 1. Screw rods 42 are rotatably provided on both sides of the top of the frame 2. The screw rods 42 are connected to the output shaft of the servo motor 41 on the same side through a coupling. Nuts 43 are threadedly connected between the screw rods 42. The left and right sides of the front side of the nut 43 are fixed with second connecting rods 44 by bolts. The front sides of the second connecting rods 44 are fixed with third connecting rods 45 for unfolding the mesh cloth by bolts.

[0035] Reference Figure 4-6 The clamping assembly 5 includes a first guide rail 51, a fourth connecting rod 52, a first spring 53, a first driving rod 54, a fifth connecting rod 55, a second spring 56, a sixth connecting rod 57, an L-shaped connecting rod 58 and a third spring 59. The first guide rails 51 are provided on both sides of the lower part of the frame 2. The fourth connecting rod 52 is slidably provided between the first guide rails 51. Two first springs 53 are connected between the fourth connecting rod 52 and the frame 2. The first springs 53 are both sleeved on the first guide rails 51. The first driving rod 54 is slidably provided on both sides of the rear side of the frame 2. The first driving rod 54 moves upward. The fifth connecting rod 55 is slidably provided between the front sides of the first connecting rod 3 for sticking the mesh cloth on the wall, and the left and right sides of the fifth connecting rod 55 are connected with the first connecting rod 3 on the same side, and the left and right sides of the top of the fifth connecting rod 55 are provided with L-shaped connecting rods 58, and the left and right sides of the front side of the fourth connecting rod 52 are provided with sixth connecting rods 57, and the sixth connecting rods 57 are slidably connected with the L-shaped connecting rod 58 on the same side, and the sixth connecting rods 57 are connected with the L-shaped connecting rod 58 on the same side. The lower side of the first driving rod 54 is inclined.

[0036] When using the device, first bring the device close to the wall, fix one end of the mesh cloth on the third connecting rod 45 with the help of a tool, start the servo motor 41, and the output shaft of the servo motor 41 rotates to drive the screw rod 42 to rotate, thereby driving the nut 43 to move upward, and the nut 43 drives the second connecting rod 44 to move upward, thereby driving the third connecting rod 45 to move upward, and the mesh cloth is unfolded. When the nut 43 contacts the first driving rod 54, it drives the first driving rod 54 to move upward. When the first driving rod 54 contacts the fourth connecting rod 52, since the lower side of the first driving rod 54 is inclined, the fourth connecting rod 52 is squeezed forward, the first spring 53 is compressed, and the fourth connecting rod 52 drives the fifth connecting rod 55, the sixth connecting rod 57, the L-shaped connecting rod 58 and the third spring 59 to move forward, and the second spring 56 is stretched. When the fifth connecting rod 55 contacts the mesh cloth, the mesh cloth is moved forward and attached to it. On the wall, the mesh cloth is fixed on the wall to reduce the intensity of construction. When the first driving rod 54 continues to squeeze the fourth connecting rod 52 forward, the fourth connecting rod 52 drives the sixth connecting rod 57 to move forward, and the third spring 59 is compressed. At this time, the servo motor 41 is turned off. After plastering is completed, the mesh cloth is loosened, and the lower side of the mesh cloth is cut off with the help of a shearing tool. Then the servo motor 41 is started, and the output shaft of the servo motor 41 is controlled to reverse to drive the screw rod 42 to reverse, thereby driving the nut 43, the second connecting rod 44 and the third connecting rod 45 to move downward and reset. Then the servo motor 41 is turned off, and the nut 43 is separated from the first driving rod 54. Due to gravity, the first driving rod 54 moves downward and resets and separates from the fourth connecting rod 52. At the same time, under the action of the first spring 53, the second spring 56 and the third spring 59 resetting, the fourth connecting rod 52, the fifth connecting rod 55, the sixth connecting rod 57 and the L-shaped connecting rod 58 are reset backward.

[0037] Example 2

The clamping assembly 6 includes a connecting sleeve 61, a U-shaped connecting rod 62, a fourth spring 63, a clamping rod 64 and a guide block 65. A connecting sleeve 61 is provided in the middle of the two second connecting rods 44. A U-shaped connecting rod 62 is slidably provided between the connecting sleeves 61. A clamping rod 64 for fixing the mesh cloth and sticking it to the wall is provided on the front side of the U-shaped connecting rod 62. The left and right sides of the clamping rod 64 are connected to the connecting sleeve 61 on the same side with a fourth spring 63. The fourth spring 63 is sleeved on the U-shaped connecting rod 62 on the same side. Guide blocks 65 are provided on the left and right sides of the top of the frame 2. After the U-shaped connecting rod 62 moves upward, it contacts the two guide blocks 65.

[0039] When the second connecting rod 44 moves upward, it drives the connecting sleeve 61 upward, and the connecting sleeve 61 drives the U-shaped connecting rod 62, the fourth spring 63 and the clamping rod 64 upward. When the U-shaped connecting rod 62 contacts the guide block 65, the guide block 65 squeezes the U-shaped connecting rod 62 forward, and the U-shaped connecting rod 62 drives the clamping rod 64 forward. The fourth spring 63 is stretched, so that the clamping rod 64 drives the mesh cloth forward and sticks to the wall. In this way, people do not need to manually press the mesh cloth to stick to the wall, which makes it easier for people to plaster. When the second connecting rod 44 moves downward, it drives the connecting sleeve 61 downward, and the connecting sleeve 61 drives the U-shaped connecting rod 62, the fourth spring 63 and the clamping rod 64 to move downward and reset. The U-shaped connecting rod 62 is separated from the guide block 65, and then the U-shaped connecting rod 62 and the clamping rod 64 are driven to move backward and reset under the action of the reset of the fourth spring 63.

Then, one end of the mesh cloth is placed between the connecting plate 71 and the third connecting rod 45, and the seventh connecting rod 72 is released. Then, under the action of the fifth spring 73 returning to its original position, the seventh connecting rod 72 and the connecting plate 71 are driven to move backward and return to their original position, so that the connecting plate 71 clamps the mesh cloth. When the third connecting rod 45 moves upward, the connecting plate 71, the seventh connecting rod 72 and the fifth spring 73 are driven upward, thereby the mesh cloth is released. The mesh cloth is unfolded, so people do not need to use tools to fix one end of the mesh cloth on the third connecting rod 45. When people have finished plastering, they manually move the seventh connecting rod 72 forward, the fifth spring 73 is compressed, and the seventh connecting rod 72 drives the connecting plate 71 to move forward, loosen the mesh cloth, and then stick the clamped end to the wall, so that the mesh cloth is separated from the connecting plate 71 and the third connecting rod 45. Then people loosen the seventh connecting rod 72, and then the fifth spring 73 is reset to drive the seventh connecting rod 72 and the connecting plate 71 to move backward and reset.

When the nut 43 moves upward, it drives the second connecting rod 44, the third connecting rod 45, the connecting plate 71, the seventh connecting rod 72 and the fifth spring 73 to move upward, and the mesh cloth is unfolded. When the nut 43 contacts the second driving rod 86, it drives the second driving rod 86 to move upward, and the second driving rod 86 drives the eighth connecting rod 82 to move upward, so that the magnet 85 is separated from the eighth connecting rod 82, and then the eighth connecting rod 82 is driven to move upward under the action of the sixth spring 84 resetting, and the eighth connecting rod 82 drives the ninth connecting rod 83 to move upward. When the nut 43 moves downward, it drives the second connecting rod 44, the third connecting rod 45, the connecting plate 71, the seventh connecting rod 72 and the fifth spring 73 to move downward and reset.
