[0018] S2: Turn on the electric lifting rod to extend it, and the inner rod extends toward the chain rack, so that the four electric lifting rods and the inner rod support the chain rack into a rectangular shape;

[0019] S3: Move the gear to mesh with the chain rack. The gear slides on the slide bar and rotates along the chain rack for one circle. Mark the longest and shortest distances of the gear displacement and insert a limit block at the position of the corresponding small hole on the slide bar.

Driven by the servo motor, it can be ensured that the device can drill a rectangular hole at one time.

[0024] 2. In the building wall punching device, the diameters of the distances between the sides of the chain rack and the connecting shaft are different. The gear rotates along the chain rack and slides on the slide rod. The spring can be extended and retracted during the sliding process. Under the action of the spring, it can be ensured that the gear can always rotate and rotate in contact with the side wall of the chain rack, which is convenient for improving the stability of the second drill bit. With the cooperation of the limit rod, the limit block and the small hole, the moving distance of the gear can be limited, further improving the stability of the gear and the second drill bit.

[0025] 3. The building wall punching device can facilitate the disassembly of the chain rack and the extrusion rod after the threaded column is removed from the inner rod, and can also facilitate the replacement of the chain rack. The electric lifting rod is turned on to extend it, and the distance between the inner rods is increased, so that a chain rack with a larger diameter can be installed. Therefore, the rectangle drilled by the second drill bit can be enlarged, which is convenient for drilling rectangular holes of different sizes.

[0026] 4. In the drilling process of the building wall punching device, a small circular hole is first drilled by the first drill bit, and the bearing capacity of the wall after the hole is opened is reduced.

[0036] One end of the screw rod 23 is externally connected to a motor to drive the screw rod 23 to rotate. During the rotation of the screw rod 23, the first slider 34 and the support frame 3 can be driven to lift up, so as to facilitate moving the first drill bit 8 to a suitable position.

[0037] The second slider 21 is an electric slider, and the support base 1 forms an electric slide rail, which cooperates with each other to drive the vertical rod 2 to slide along the second slide groove 11, so as to drive the support frame 3 and the first drill bit 8 at its upper end to drill into the wall.

[0038] After the first drill bit 8 is adjusted to a suitable position, the servo motor 32 is turned on, and the servo motor 32 drives the connecting shaft 33 and the first drill bit 8 to rotate, thereby punching a circular hole in the wall, thereby completing the hole drilling work.

[0049] Example 3

[0050] This embodiment is intended to facilitate solving the problem of how to drill rectangular holes of different sizes. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-4 A cavity 411 is also provided in the support rod 41 , and an electric lifting rod 412 is installed in the cavity 411 . An inner rod 413 is fixedly installed at one end of the electric lifting rod 412 , and one end of the inner rod 413 is slidably connected to the chain rack 42 .

[0051] The electric lifting rod 412 is turned on to extend it, and the distance between the inner rods 413 can be increased, so that the chain rack 42 with a larger diameter can be installed, so the rectangle drilled by the second drill bit 7 can be enlarged.

[0052] An extrusion rod 44 is inserted through one end of the inner rod 413 away from the electric lifting rod 412 , a suction cup 45 is fixedly mounted on one end of the extrusion rod 44 , and a first limiting plate 43 is fixed on the middle part of the extrusion rod 44 .

[0053] The extrusion rod 44 is an elastic telescopic rod structure. During the drilling process of the first drill bit 8, the suction cup 45 can always be against the wall surface, so as to ensure the stability of the device during the drilling process.

[0054] By installing the first limiting plate 43, it is convenient to limit the inner rod 413 to prevent it from sliding.

[0055] A screw hole 48 is formed at one end of the extrusion rod 44 away from the suction cup 45 , a threaded column 47 is threadedly connected to the screw hole 48 , a second limiting plate 46 is fixedly mounted at one end of the threaded column 47 , and the first limiting plate 43 and the second limiting plate 46 are mounted at both ends of the inner rod 413 .

[0057] After the threaded column 47 is removed from the inner rod 413, it is convenient to remove the chain rack 42 and the extrusion rod 44, to replace the chain rack 42, and to drill rectangular holes of different sizes.

[0058] In order to further better explain the above embodiment, the present invention also provides an implementation scheme, a method for using a building wall punching device, comprising the following steps:

[0059] Step 1: Rotate the second limiting plate 46 to remove the threaded column 47 from the inner rod 413, sleeve the chain rack 42 of appropriate size onto the inner rod 413, and then tighten the threaded column 47;

[0060] Step 2: Turn on the electric lifting rod 412 to extend it, and the inner rod 413 extends toward the chain rack 42, so that the four electric lifting rods 412 and the inner rod 413 support the chain rack 42 into a rectangular shape;

[0061] Step 3: Move the gear 6 to mesh with the chain rack 42, slide the gear 6 on the slide bar 5, and rotate it along the chain rack 42 for one circle, mark the longest and shortest distances of the gear 6 displacement, and insert the limit block 55 into the corresponding position of the small hole 54 on the slide bar 5;

[0062] Step 4: Move the device to one side of the desired wall, rotate the screw rod 23, and drive the support frame 3 to lift up as a whole;

[0063] Step 5: The first drill bit 8 is adjusted to a suitable position, and the servo motor 32 is turned on. The servo motor 32 drives the connecting shaft 33, the first drill bit 8 and the second drill bit 7 connected to the gear 6 to rotate, thereby making a circular or rectangular hole in the wall.

[0064] During the drilling process, the first drill bit 8 first drills a small circular hole, and the bearing capacity of the wall after the hole is opened is reduced. Then the second drill bit 7 drills a rectangular hole, which is convenient for reducing the burden of the second drill bit 7 and making it easier to form the rectangular hole.

[0065] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
