DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1

[0026] Reference Figure 1 and Figure 2 , is the first embodiment of the utility model, which provides a wall opening device that is easy to locate, including:

[0027] The hole-opening mechanism 100 includes an electric drill housing 101 , and a drill bit clamp 102 is adapted to be mounted on one side of the outer surface of the electric drill housing 101 ;

[0028] Among them, the electric drill housing 101 is made of reinforced nylon PA6-GF30 material with reinforcement, high heat resistance, high rigidity and high strength. Compared with ordinary nylon, the nylon with added nylon glass fiber has strong rigidity retention, good deformation resistance, and improved dimensional stability, wear resistance and high temperature resistance.

[0029] The positioning mechanism 200 includes a support frame 201 disposed below the electric drill housing 101, and a connecting shaft 202 is rotatably connected to one side of the inner surface of the support frame 201;

[0030] The support frame 201 is used to support the connecting shaft 202 . The connecting shaft 202 is located on the surface of the support frame 201 and is fixedly connected with a friction plate.

[0031] The driving mechanism 300 includes a support plate 301 disposed directly above the support frame 201 , and a top surface of the support plate 301 is fixedly connected to a limiting slide rail 302 .

[0032] The support plate 301 is used to support the limiting slide rail 302 .

[0033] Specifically, a drill bit 103 is disposed on the inner surface of the drill bit holder 102 , and a power switch 104 is disposed on the outer surface of the electric drill housing 101 .

[0034] Among them, the drill bit clamp 102 can facilitate the user to replace different types of drill bits 103 according to actual conditions. The drill bit 103 is made of high-speed steel HSS with good toughness. The high-speed steel drill bit 103 can resist impact and vibration to a certain extent and reduce the risk of drill bit breakage. During the drilling process, the high-speed steel drill bit 103 can maintain stable cutting performance and ensure the accuracy and efficiency of drilling. The power switch 104 can control the drill bit 103 to rotate or stop.

[0035] When in use, the user replaces the drill bit 103 with a suitable model through the drill bit clamp 102 according to actual conditions, and turns on the power switch 104 to control the drill bit 103 to rotate, so as to start the wall drilling work.

[0036] In summary, the hole-drilling mechanism 100 adopts a mechanized operation mode, which can relatively easily complete the hole-drilling process and greatly improve the construction efficiency, so as to achieve the effect of reducing labor costs and construction time.

[0037] Example 2

[0038] Reference Figure 1 , Figure 3 and Figure 4, which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides the structure of the positioning mechanism 200 and a specific implementation method for automatically positioning the hole-opening device after adjusting it to a suitable position.

[0039] Specifically, one end of the connecting shaft 202 is fixedly connected to the rocker 203, the other end of the connecting shaft 202 is fixedly connected to the first screw rod 204, the other end of the first screw rod 204 is fixedly connected to the second screw rod 205, and the other end of the second screw rod 205 is fixedly installed on one side surface of the inner wall of the support frame 201 through a bearing.

[0040] The thread directions of the first screw rod 204 and the second screw rod 205 are opposite.

[0041] Furthermore, the positioning mechanism 200 also includes two internal thread blocks 206 , which are respectively threadedly connected to the surfaces of the first screw rod 204 and the second screw rod 205 , and the outer surfaces of the two internal thread blocks 206 are respectively hinged with hinge rods 207 on both sides.

[0042] The other ends of the four hinged rods 207 are respectively hinged to the bottom surface of the support plate 301.

[0043] Preferably, the positioning mechanism 200 also includes a swivel column 208, the number of which is two, and the two swivel columns 208 are fixedly connected to one side of the outer surface of the support frame 201. The surfaces of the two swivel columns 208 are rotatably connected to friction blocks 209 respectively, and the surface of one side of the two friction blocks 209 is fixedly connected to the same spring 210.

[0044] The end surfaces of the two friction blocks 209 are tightly fitted with the friction plates on the surface of the connecting shaft 202 , and the end surfaces of the two friction blocks 209 are respectively fixedly connected with the friction plates.

[0045] When in use, after the support frame 201 is moved to a suitable position by the pulley, one end of the two friction blocks 209 is pressed down, and a pressure is applied to the spring 210, so that the friction plates on the end faces of the two friction blocks 209 are out of contact with the friction plates on the surface of the connecting shaft 202, and the rocker 203 is rotated to drive the first screw rod 204 and the second screw rod 205 to rotate synchronously, and the two internal thread blocks 206 are limited by the cooperation between the support plate 301 and the hinge rod 207, so that the two internal thread blocks 206 drive one end of the hinge rod 207 to move toward each other. The other end of the hinge rod 207 lifts the support plate 301 to a suitable height, and the friction block 209 is released, so that the spring 210 resets the two friction blocks 209 through the reaction force, so that the friction plates on the end faces of the two friction blocks 209 are in contact with the friction plates on the surface of the connecting shaft 202, thereby limiting the connecting shaft 202, so as to prevent the position of the hole-opening device from being offset due to the rocker 203 being accidentally touched during the hole-opening process.

[0046] In summary, through the automatic positioning function of the positioning mechanism 200, it can ensure that each hole is opened at the predetermined precise position, avoiding positioning errors caused by human factors, thereby improving the processing accuracy and consistency of the wall holes, and greatly reducing the time spent by operators on adjusting the position of the hole opening device, making the entire processing process smoother. Once the positioning is completed, the hole opening device can start working immediately without waiting for manual confirmation, thereby improving the continuous operation capacity of the hole opening work.

[0047] Example 3

[0048] Reference Figure 1 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides the structure of the driving mechanism 300 and a specific implementation method for controlling the depth of the wall opening.

[0049] Specifically, a sliding block 303 is slidably connected to the surface of the limiting sliding rail 302 , and a motor 304 is adapted to be installed on the top surface of the supporting plate 301 .

[0050] The limiting slide rail 302 is used to limit the slider 303 .

[0051] Furthermore, the driving mechanism 300 also includes a third screw rod 305 fixedly connected to the output end of the motor 304 , and an internal thread sleeve 306 is threadedly connected to the surface of the third screw rod 305 .

[0052] One end of the internal thread sleeve 306 is fixedly connected to the outer surface of the electric drill housing 101 .

[0053] When in use, the motor 304 is turned on to drive the third screw rod 305 to rotate synchronously. The slider 303 is limited by the limiting slide rail 302, so that the slider 303 limits the electric drill housing 101, and then the electric drill housing 101 limits the internal threaded sleeve 306, so that the internal threaded sleeve 306 drives the electric drill housing 101 to move linearly by driving the rotation of the third screw rod 305, so that the electric drill housing 101 drives the drill bit 103 to move linearly, so as to achieve the effect of facilitating the user to control the depth of the wall hole.

[0054] In summary, by setting up the driving mechanism 300, the user can control the depth of the wall opening, thereby reducing the need for rework due to improper hole depth, thereby improving work efficiency. At the same time, it can also avoid excessive damage to the wall material to a certain extent, protect its integrity and aesthetics, and achieve the effect of extending the service life of the wall.
