Description

Technical Field

[0001] This invention belongs to the field of exterior wall construction, specifically a construction device for exterior wall stone paint expansion joints. Background Technology

[0002] Walls can be divided into interior walls and exterior walls. From an architectural perspective, the components that enclose a building and form the boundary between the interior and exterior are called exterior walls. Real stone paint is a coating that has a decorative effect similar to marble and granite. It is mainly made of natural stone powder of various colors and is used to create a stone-like effect on the exterior walls of buildings. Therefore, it is also known as liquid stone.

[0003] Expansion joints are pre-installed joints in the roof leveling layer, rigid waterproof layer, and rigid protective layer to reduce cracking. The rigid protective layer only has V-shaped grooves on its surface, called surface expansion joints. The traditional construction method for expansion joints is to use a veneer to adhere to the painted surface. After the veneer is adhered, paint is applied over the veneer and the entire front surface. Then the veneer is removed to complete the construction.

[0004] Traditional expansion joint construction requires the adhesive layer to be applied horizontally and vertically to the painted surface, but this requires high precision. Otherwise, the expansion joint will be too unsightly and fail to meet the standards. In the positioning process, laser positioning plus chalk line positioning is generally used to achieve accuracy. This not only affects the construction efficiency, but also makes it difficult to operate on some high walls.

[0005] Therefore, the present invention provides a construction device for the expansion joint of exterior wall stone paint. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides an exterior wall stone paint expansion joint construction device, including a movable box, the bottom of which is open, multiple levels fixed to the top of which are fixed, electric wheels installed at the four corners of the bottom of which are mounted, a navigation module fixed to the top of which is fixed, a guide block fixed to the outside of which is fixed, two symmetrically arranged negative pressure modules fixed to the bottom of which are fixed, and a covering strip and an adhesive component provided below which the covering strip is used to adhere to the exterior wall surface.

[0008] By using a mobile box, a negative pressure module generates negative pressure on the bottom of the mobile box, allowing it to adhere to the wall. A navigation module controls the mobile box to move along a designated route. During movement, multiple levels measure whether the mobile box is moving horizontally, and the device's trajectory is adjusted in real time based on the feedback from the levels. The bonding component continuously adheres the covering tape to the wall, and the guide block is used to determine the device's direction of travel. With this setup, the covering tape can be neatly and orderly bonded to the wall without the need for laser positioning or chalk line positioning. Moreover, this device is more efficient and safer than traditional methods when used on higher walls.

[0009] Preferably, the bonding assembly includes an electric raw material roller and an electric recovery roller. The cover belt is connected between the electric raw material roller and the electric recovery roller. Two symmetrically arranged separation belts are bonded to the side of the cover belt away from the wall. The electric raw material roller winds up a large amount of cover belt, and the other end of the cover belt is connected to the electric recovery roller. As the equipment moves, the electric raw material roller and the electric recovery roller rotate synchronously, allowing the cover belt to be continuously released. One side of the cover belt has adhesive, which adheres to the wall after contacting it, and then separates from the separation belt. The separation belt continues to be recovered by the electric recovery roller. When it is necessary to bond the cover belt, simply cut the cover belt and bond one end to the wall. During the movement of the moving box, the cover belt can be continuously bonded to the wall.

[0010] Preferably, a vertically installed electric telescopic rod is fixed to the inner side of the mobile box. A separation column is fixed to the output end of the electric telescopic rod. The length of the separation column is less than the gap between the two separation strips. A cutting component is provided in the separation column. The cutting component is used to cut the covering strip. In order to ensure that the covering strip can be stably separated from the separation strip, the electric telescopic rod is activated to extend downward before bonding, so that the separation column passes through the gap between the two separation strips and presses the covering strip onto the wall. In this way, as the mobile box moves, the covering strip can be stably pressed onto the wall and separated from the separation strip. After bonding in one place, the covering strip is cut by the cutting component, and the equipment is moved to a new location to continue bonding.

[0011] Preferably, an electric telescopic rod two, which is fixedly connected to the moving box, is provided between the electric telescopic rod one and the electric raw material roller. A pressing column is fixedly connected to the bottom of the electric telescopic rod two. The length of the pressing column is longer than the width of the cover belt. During the movement of the equipment, sometimes it is not necessary to adhere to the cover belt and it is just moving. By setting the pressing column, the height of the pressing column can be adjusted by the electric telescopic rod two. The pressing column can change the distance between the cover belt and the wall. When the moving box is just moving normally, the pressing column rises, and the electric recovery roller and the electric raw material roller simultaneously rewind. While ensuring that the cover belt is taut, the bottom surface of the cover belt will not contact the wall. Moreover, the pressing column presses down the cover belt before the separation column, so that when the separation column separates the cover belt and the separation belt, the pressing angle between the separation column and the cover belt is close to 90 degrees, the force is uniform, and no large wrinkles are caused to the surface of the cover belt.

[0012] Preferably, the cutting assembly includes two cutting blades, and the separating column includes a connecting seat fixedly connected to an electric telescopic rod. Two unfolding arms are rotatably connected to the bottom surface of the connecting seat on both sides. The bottom surface of each unfolding arm is fixedly connected to the cutting blade. An unfolding assembly is provided between the unfolding arms and the connecting seat. The unfolding assembly allows the unfolding arms to unfold smoothly. When the covering tape needs to be cut, the two unfolding arms are simply unfolded using the unfolding assembly, so that they are parallel to the connecting seat. The cutting blade contacts the covering tape and repeatedly rises and falls under the drive of the electric telescopic rod, cutting a sufficiently large groove on the surface of the covering tape. Then, as the moving box moves, the covering tape can be broken, allowing the moving box to move freely. At this time, the break point is located directly below the connecting seat, allowing for direct application of the covering tape the next time it is pasted.

[0013] Preferably, the unfolding assembly includes two solenoid valves connected to the bottom surface of the connecting seat. An insertion block adapted to the solenoid valve is fixed to the unfolding arm. The connecting seat and the separating column are connected by a torsion spring. When it is necessary to open the unfolding arm, simply open the solenoid valve, and the unfolding arm will spring outward under the action of the torsion spring. After springing out, the angle between the unfolding arm and the connecting seat is greater than 90 degrees. At this time, as the electric telescopic rod 1 is pressed down, the two unfolding arms can be pressed to a horizontal state, so that the two cutting blades 1 can act on the covering belt.

[0014] Preferably, the outer side of the unfolding arm is smoothly rounded, and two electric telescopic rods are fixedly connected to the inner side of the movable box. The two electric telescopic rods are symmetrically arranged and are on the same vertical plane as the separation column. After the cutting is completed, the electric telescopic rod 1 shortens, and the two unfolding arms will disengage from the two separation belts during the rising process, thereby bringing the two unfolding arms together towards the center. The electric telescopic rod 4 is located on the side of the unfolding arm. As the electric telescopic rod 4 extends, the unfolding arm can be finally pressed into a state that is connected with the solenoid valve.

[0015] Preferably, a pressing block is fixed to the outer side of the unfolding arm, and a storage groove is opened on the bottom surface of the connecting seat. A second cutting blade is provided on the inner side of the storage groove. Two spring telescopic rods are fixed between the second cutting blade and the inner wall of the storage groove. A pop-out component is provided on the inner side of the connecting seat. The pop-out component is used to control the pop-out of the second cutting blade. In order to improve the cutting effect, after the two unfolding arms are unfolded, the pop-out component will push the second cutting blade downward to the same level as the first cutting blade, which can improve the cutting effect of the covering strip. When the two unfolding arms return to their original positions, the pop-out component closes under the action of the spring telescopic rods, and the second cutting blade will retract inward. At this time, the first cutting blade can be retracted to the position of the blade storage groove, so that the unfolding arm and the connecting seat can be neatly spliced.

[0016] Preferably, the pop-up assembly includes an air pump, the output end of which is connected to the interior of two spring telescopic rods. The control switch of the air pump is located on the outside of the connecting seat and corresponds to the moved pressing block. When the unfolding arm unfolds, as the unfolding arm presses against the wall, the pressing block triggers the air pump switch, causing the air pump to inject air pressure into the spring telescopic rods, causing the spring telescopic rods to extend and push out the second cutting blade. When the unfolding arm closes, the air pump stops working, and the internal air pressure is discharged outward along the air pump by the retraction of the spring telescopic rods, allowing the second cutting blade to return to its original position.

[0017] Preferably, a rebound arm is fixedly connected to the inner wall of the mobile box. The rebound arm is made of elastic metal material, and a pressing hammer is fixedly connected to the bottom of the rebound arm. The pressing hammer is located above the covering strip. An electric telescopic rod three is fixedly connected to the inner wall of the mobile box. The output end of the electric telescopic rod three is fixedly connected to the rebound arm. In order to improve the adhesion between the covering strip and the wall, the electric telescopic rod three is activated to repeatedly extend and retract during the adhesion process, which drives the rebound arm and the pressing hammer to continuously hammer the covering strip. Since the rebound arm is made of elastic material, it will continuously deform during the movement, which not only makes the hammering force moderate, but also prevents the elastic material rebound arm from easily breaking.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The exterior wall stone paint expansion joint construction device of the present invention generates negative pressure on the bottom surface of the moving box through a negative pressure module, allowing the entire moving box to adhere to the wall surface. The moving box is controlled by a navigation module to move along a designated route. During the movement, multiple levels measure whether the moving box is moving horizontally. The movement trajectory of the device is adjusted in a timely manner based on the information fed back by the levels. The covering tape is continuously adhered to the wall surface by the bonding component. The guide block is used to determine the forward direction of the device. With this setting, the covering tape can be neatly and orderly adhered to the wall surface without the need for laser positioning and chalk line positioning. Moreover, this device is more efficient and safer than traditional methods when used on higher walls.

[0020] 2. The exterior wall stone paint separation joint construction device of the present invention uses an electric material roller to wind up a large amount of covering tape. The other end of the covering tape is connected to an electric recovery roller. As the equipment moves, the electric material roller and the electric recovery roller rotate synchronously, allowing the covering tape to be continuously released. One side of the covering tape has adhesive, which adheres to the wall surface after contacting it, and then separates from the separation tape. The separation tape continues to be recovered by the electric recovery roller. When it is necessary to attach the covering tape, simply cut the covering tape and attach one end to the wall surface. During the movement of the moving box, the covering tape can be continuously attached to the wall surface. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 2As shown in the embodiment of the present invention, an exterior wall stone paint expansion joint construction device includes a movable box 1. The bottom of the movable box 1 is open. Multiple levels 5 are fixed to the top of the movable box 1. Electric wheels 2 are installed at the four corners of the bottom of the movable box 1. A navigation module 4 is fixed to the top of the movable box 1. A guide block 6 is fixed to the outside of the movable box 1. Two negative pressure modules 7 are fixed to the bottom of the movable box 1 in a symmetrical arrangement. A covering strip 3 and an adhesive component are arranged below the movable box 1. The adhesive component is used to adhere the covering strip 3 to the exterior wall surface.

[0031] During the work, traditional expansion joint construction requires the covering tape to be applied horizontally and vertically to the painted surface. However, this requires high precision, otherwise the expansion joint will be too unsightly and fail to meet the standards. In the positioning process, laser positioning plus chalk line positioning is generally used to achieve accuracy. This not only affects the construction efficiency, but also makes it difficult to operate on some high walls.

[0032] By setting up the mobile box 1, negative pressure is generated on the bottom surface of the mobile box 1 by the negative pressure module 7, allowing the entire mobile box 1 to adhere to the wall. The navigation module 4 controls the movement of the mobile box 1 along a designated route. During the movement, multiple levels 5 measure whether the mobile box 1 is moving horizontally. The information fed back by the levels 5 is used to adjust the movement trajectory of the device in a timely manner. The covering tape 3 is continuously adhered to the wall by the bonding component. The guide block 6 is used to determine the forward direction of the device. With this setting, the covering tape 3 can be neatly and orderly adhered to the wall without the need for laser positioning and chalk line positioning. Moreover, this device is more efficient and safer than traditional methods when used on higher walls.

[0033] like Figures 2 to 4 As shown, the bonding assembly includes an electric raw material roller 9 and an electric recycling roller 8. The covering belt 3 is connected between the electric raw material roller 9 and the electric recycling roller 8. Two symmetrically arranged separation belts 15 are bonded to the side of the covering belt 3 away from the wall.

[0034] During operation, the electric raw material roller 9 winds up a large amount of cover strip 3. The other end of the cover strip 3 is connected to the electric recovery roller 8. As the equipment moves, the electric raw material roller 9 and the electric recovery roller 8 rotate synchronously, allowing the cover strip 3 to be continuously released. One side of the cover strip 3 has adhesive, which adheres to the wall surface after contact with it, and then separates from the separation belt 15. The separation belt 15 continues to be recovered by the electric recovery roller 8. When it is necessary to adhere the cover strip 3, simply cut the cover strip 3 and adhere one end to the wall surface. During the movement of the moving box 1, the cover strip 3 can be continuously adhered to the wall surface.

[0035] like Figures 2 to 7As shown, a vertically arranged electric telescopic rod 11 is fixedly connected to the inner side of the mobile box 1. A separation column 16 is fixedly connected to the output end of the electric telescopic rod 11. The length of the separation column 16 is less than the gap between the two separation strips 15. A cutting component is provided in the separation column 16. The cutting component is used to cut the covering strip 3.

[0036] During operation, in order to ensure that the covering tape 3 can be stably separated from the separating tape 15, the electric telescopic rod 11 is activated before bonding and extends downward, allowing the separating column 16 to pass through the gap between the two separating tapes 15, pressing the covering tape 3 against the wall. In this way, as the moving box 1 moves, the covering tape 3 can be stably pressed against the wall and separated from the separating tape 15. After bonding in one location, the covering tape 3 is cut by the cutting component, allowing the equipment to be moved to a new location to continue bonding.

[0037] like Figures 2 to 7 As shown, an electric telescopic rod 13 is provided between the electric telescopic rod 11 and the electric raw material roller 9 and is fixedly connected to the moving box 1. A pressure column 12 is fixedly connected to the bottom of the electric telescopic rod 13. The length of the pressure column 12 is longer than the width of the covering belt 3.

[0038] During operation, when the equipment moves, sometimes it is not necessary to adhere to the cover belt 3 and it is simply moving. Through the setting of the pressure column 12, the height of the pressure column 12 can be adjusted by the electric telescopic rod 13. The pressure column 12 can change the distance between the cover belt 3 and the wall. When the moving box 1 is just moving normally, the pressure column 12 rises, and at the same time the electric recovery roller 8 and the electric raw material roller 9 are wound up synchronously. While ensuring that the cover belt 3 is taut, the bottom surface of the cover belt 3 will not contact the wall. Moreover, the pressure column 12 presses down the cover belt 3 before the separation column 16, so that when the separation column 16 separates the cover belt 3 and the separation belt 15, the pressing angle between the separation column 16 and the cover belt 3 is close to ninety degrees, the force is uniform, and it will not cause large wrinkles on the surface of the cover belt 3.

[0039] like Figures 2 to 7 As shown, the cutting assembly includes two cutting blades 18, and the separating column 16 includes a connecting seat 21 fixedly connected to the electric telescopic rod 11. The bottom surface of the connecting seat 21 is rotatably connected to two unfolding arms 17 on both sides. The bottom surface of the unfolding arms 17 is fixedly connected to the cutting blades 18. An unfolding assembly is provided between the unfolding arms 17 and the connecting seat 21. The unfolding assembly is used to allow the unfolding arms 17 to unfold smoothly.

[0040] When it is necessary to cut the cover strip 3 during operation, simply unfold the two unfolding arms 17 through the unfolding assembly, so that the two unfolding arms 17 are parallel to the connecting seat 21. The cutting blade 18 contacts the cover strip 3 and repeatedly rises and falls under the drive of the electric telescopic rod 11 to cut a sufficiently broken groove on the surface of the cover strip 3. Then, as the moving box 1 moves, the cover strip 3 can be pulled off, allowing the moving box 1 to move freely. At this time, the broken position is just below the connecting seat 21, so that the cover strip 3 can be directly attached the next time it is pasted.

[0041] like Figures 2 to 7 As shown, the unfolding assembly includes two solenoid valves 26, which are connected to the bottom surface of the connecting seat 21. An insertion block adapted to the solenoid valves 26 is fixed on the unfolding arm 17. The connecting seat 21 and the separating column 16 are connected by a torsion spring.

[0042] When it is necessary to open the unfolding arm 17 during operation, simply open the solenoid valve 26, and the unfolding arm 17 will spring outward under the action of the torsion spring. After it springs out, the angle between the unfolding arm 17 and the connecting seat 21 is greater than 90 degrees. At this time, as the electric telescopic rod 11 is pressed down, the two unfolding arms 17 can be pressed to a horizontal state, so that the two cutting blades 18 can act on the covering belt 3.

[0043] like Figures 2 to 7 As shown, the outer side of the unfolding arm 17 is smoothly rounded, and two electric telescopic rods are fixed to the inner side of the movable box 1. The two electric telescopic rods are symmetrically arranged, and the electric telescopic rods and the separation column 16 are on the same vertical plane.

[0044] During operation, after the cutting is completed, the electric telescopic rod 11 is shortened. During the ascent, the two unfolding arms 17 will disengage from the two separation belts 15, thereby bringing the two unfolding arms 17 together towards the center. The electric telescopic rod 4 is located on the side of the unfolding arms 17. As the electric telescopic rod 4 extends, it can finally press the unfolding arms 17 into a state that is connected with the solenoid valve 26.

[0045] like Figures 2 to 7 As shown, a pressing block 25 is fixedly connected to the outer side of the unfolding arm 17, and a storage groove 19 is opened on the bottom surface of the connecting seat 21. A cutting blade 24 is provided on the inner side of the storage groove 19. Two spring telescopic rods 23 are fixedly connected between the cutting blade 24 and the inner wall of the storage groove 19. A pop-out component is provided on the inner side of the connecting seat 21. The pop-out component is used to control the pop-out of the cutting blade 24.

[0046] During operation, in order to improve the cutting effect, after the two unfolding arms 17 are unfolded, the pop-up component will push the second cutting blade 24 downward to a state flush with the first cutting blade 18, which can improve the cutting effect of the covering strip 3. When the two unfolding arms 17 return to their original positions, the pop-up component closes under the action of the spring telescopic rod 23, and the second cutting blade 24 will retract inward. At this time, the first cutting blade 18 can be retracted to the position of the blade storage slot 19, so that the unfolding arms 17 and the connecting seat 21 can be neatly spliced ​​together.

[0047] like Figures 2 to 7 As shown, the pop-out assembly includes an air pump, the output end of which is connected to the interior of two spring telescopic rods 23. The control switch of the air pump is located on the outside of the connecting seat 21 and corresponds to the moved pressing block 25.

[0048] During operation, when the unfolding arm 17 is extended, as it presses against the wall, the pressing block 25 triggers the air pump switch, causing the air pump to inject air pressure into the spring telescopic rod 23, which then extends and pushes out the second cutting blade 24. When the unfolding arm 17 closes, the air pump stops working, and the internal air pressure is discharged outward along the air pump by the retraction of the spring telescopic rod 23, allowing the second cutting blade 24 to return to its original position.

[0049] like Figures 2 to 7 As shown, a spring arm 20 is fixedly connected to the inner wall of the mobile box 1. The spring arm 20 is made of elastic metal material. A pressing hammer 10 is fixedly connected to the bottom of the spring arm 20. The pressing hammer 10 is located above the covering belt 3. An electric telescopic rod 14 is fixedly connected to the inner wall of the mobile box 1. The output end of the electric telescopic rod 14 is fixedly connected to the spring arm 20.

[0050] During operation, in order to improve the adhesion between the covering strip 3 and the wall, the electric telescopic rod 14 is repeatedly extended and retracted during the adhesion process, which drives the rebound arm 20 and the pressing hammer 10 to continuously hammer the covering strip 3. Since the rebound arm 20 is made of elastic material, it will deform continuously during the movement, which not only makes the hammering force moderate, but also prevents the elastic material rebound arm 20 from breaking easily.

[0051] During operation, the negative pressure module 7 generates negative pressure on the bottom of the mobile box 1, allowing it to adhere to the wall. The navigation module 4 controls the mobile box 1 to move along a designated route. During the movement, multiple levels 5 measure whether the mobile box 1 is moving horizontally. The information fed back by the levels 5 is used to adjust the movement trajectory of the device in a timely manner. The covering tape 3 is continuously adhered to the wall by the bonding component. The guide block 6 is used to determine the forward direction of the device. With this setup, the covering tape 3 can be neatly and orderly adhered to the wall without the need for laser positioning and chalk line positioning. Moreover, this device is more efficient and safer than traditional methods when used on higher walls.

[0052] The electric raw material roller 9 winds up a large amount of cover strip 3. The other end of the cover strip 3 is connected to the electric recovery roller 8. As the equipment moves, the electric raw material roller 9 and the electric recovery roller 8 rotate synchronously, allowing the cover strip 3 to be continuously released. One side of the cover strip 3 has adhesive, which will stick to the wall after contacting it, and then separate from the separation belt 15. The separation belt 15 continues to be recovered by the electric recovery roller 8. When it is necessary to stick the cover strip 3, simply cut the cover strip 3 and stick the cut end to the wall. During the movement of the moving box 1, the cover strip 3 can be continuously stuck to the wall.

[0053] To ensure that the covering tape 3 can be stably separated from the separating tape 15, the electric telescopic rod 11 is activated before bonding and extends downward, allowing the separating column 16 to pass through the gap between the two separating tapes 15, pressing the covering tape 3 against the wall. In this way, as the moving box 1 moves, the covering tape 3 can be stably pressed against the wall and separated from the separating tape 15. After bonding in one location, the covering tape 3 is cut by the cutting component, and the equipment is moved to a new location to continue bonding.

[0054] During equipment movement, sometimes it is not necessary to adhere to the cover belt 3 and the movement is simple. By setting the pressure column 12, the height of the pressure column 12 can be adjusted by the electric telescopic rod 13. The pressure column 12 can change the distance between the cover belt 3 and the wall. When the moving box 1 is just moving normally, the pressure column 12 rises, and at the same time the electric recovery roller 8 and the electric raw material roller 9 are wound up synchronously. While ensuring that the cover belt 3 is taut, the bottom surface of the cover belt 3 will not contact the wall. Moreover, the pressure column 12 presses down the cover belt 3 before the separation column 16, so that when the separation column 16 separates the cover belt 3 and the separation belt 15, the pressing angle between the separation column 16 and the cover belt 3 is close to ninety degrees, the force is uniform, and it will not cause large wrinkles on the surface of the cover belt 3.

[0055] When it is necessary to cut the covering strip 3, simply unfold the two unfolding arms 17 through the unfolding assembly, so that the two unfolding arms 17 are parallel to the connecting seat 21. The cutting blade 18 contacts the covering strip 3 and repeatedly rises and falls under the drive of the electric telescopic rod 11 to cut a sufficiently broken groove on the surface of the covering strip 3. Then, as the moving box 1 moves, the covering strip 3 can be pulled off, allowing the moving box 1 to move freely. At this time, the broken position is just below the connecting seat 21, so that the covering strip 3 can be directly attached the next time it is pasted.

[0056] When it is necessary to open the unfolding arm 17, simply open the solenoid valve 26, and the unfolding arm 17 will spring outward under the action of the torsion spring. After it springs out, the angle between the unfolding arm 17 and the connecting seat 21 is greater than 90 degrees. At this time, as the electric telescopic rod 11 is pressed down, the two unfolding arms 17 can be pressed to a horizontal state, so that the two cutting blades 18 can act on the covering belt 3.

[0057] After the cutting is completed, the electric telescopic rod 11 is shortened. During the rising process, the two unfolding arms 17 will be released from the two separation belts 15, thereby bringing the two unfolding arms 17 together towards the center. The electric telescopic rod 4 is located on the side of the unfolding arms 17. As the electric telescopic rod 4 extends, the unfolding arms 17 can be finally pressed together to the state of being combined with the solenoid valve 26.

[0058] To improve the cutting effect, after the two unfolding arms 17 are unfolded, the pop-out component will push the second cutting blade 24 downward to the same level as the first cutting blade 18, which can improve the cutting effect of the covering strip 3. When the two unfolding arms 17 return to their original positions, the pop-out component closes under the action of the spring telescopic rod 23, and the second cutting blade 24 will retract inward. At this time, the first cutting blade 18 can be retracted to the position of the blade storage slot 19, so that the unfolding arms 17 and the connecting seat 21 can be neatly spliced ​​together.

[0059] When the extension arm 17 is extended, as the extension arm 17 presses against the wall, the pressing block 25 will trigger the air pump switch, allowing the air pump to inject air pressure into the spring telescopic rod 23, causing the spring telescopic rod 23 to extend and push out the second cutting blade 24. When the extension arm 17 is closed, the air pump stops working, and under the retraction of the spring telescopic rod 23 itself, the internal air pressure will be discharged outward along the air pump, allowing the second cutting blade 24 to return to its position.

[0060] To improve the adhesion between the covering strip 3 and the wall, during the adhesion process, the electric telescopic rod 14 is repeatedly extended and retracted, driving the rebound arm 20 and the pressing hammer 10 to continuously hammer the covering strip 3. Since the rebound arm 20 is made of elastic material, it will continuously deform during the movement, which not only makes the hammering force moderate, but also prevents the elastic material rebound arm 20 from easily breaking.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
