Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
As shown in fig. 1 to 3, the hole diameter adjustable drilling tool 10 of the present invention includes a blade 3 and a blade holder 2, and the blade 3 and the blade holder 2 are connected by a connecting bolt 5. In some embodiments, the blade holder 2 is a steel block structure. Wherein the connecting bolt 5 is locked on the side wall of the blade holder 2. In one embodiment, the side wall of the blade holder 2 is provided with a groove (not shown) for accommodating the connecting bolt 5, and one end of the connecting bolt 5 is vertically screwed into a screw hole of the groove and locked by the nut 6 so that the bolt 5 is fixedly connected to the side wall of the blade holder 2. In other preferred embodiments, in order to replace the connecting bolt 5 with different lengths, a screw thread is arranged in the screw hole of the blade holder 2, and the connecting bolt 5 is locked with the screw hole of the groove in a threaded connection mode.
The top of the blade frame 2 is vertically connected with a tail rod 1, and the tail rod 1 is used for being connected with an electric drill. A positioning needle 4 is vertically connected to the bottom of the blade holder 2. The locating pin is used for positioning, is positioned at the center of a hole to be drilled, and the radius of the drilled hole is determined by the distance between the blade 3 and the locating pin 4. In some embodiments, the central line of the tail rod 1 is coincident with the central line of the positioning needle 4, i.e. the tail rod 1 and the positioning needle 4 are on the same vertical line. Thereby facilitating the positioning of the positioning pin 4.
In some embodiments, the upper portion of the blade 3 is provided with a through hole (not shown), and the connecting bolt 5 is inserted into the groove of the blade holder 2 after passing through the through hole, and then locked and fixed by the nut 6.
The utility model discloses in, blade 3 can slide on connecting bolt 5, slides through blade 3 and adjusts the distance of blade 3 apart from pilot pin 4 to adjust the aperture size that needs drilling. The blade 2 is fixed on the connecting bolt 5 through two positioning nuts 7 positioned on the connecting bolt 5, and the two positioning nuts 7 are respectively positioned at two sides of the blade 3. When the blade 3 moves on the connecting bolt 5 and is adjusted to the required drilling size, the nuts 7 on both sides of the blade 3 are screwed towards the blade 3 to lock the blade 3.
In some embodiments, in order to ensure the verticality and stability of the blade 3 during the drilling process, the bolt combination (connecting bolt 5, nut 6, two nuts 7) connecting the blade 3 and the blade holder 2 has two or more sets. Similarly, the number of the through holes on the blade 3 and the number of the grooves on the blade holder 2 which are matched with the through holes are two or more. The two or more sets of bolts are combined to be parallel up and down and connected with the blade 3 and the blade holder 2 on the same vertical line. As shown in figure 1, two groups of bolt assemblies are connected to the blade 3 and the blade holder 2 up and down, so that the blade 3 is parallel to the positioning needle 4, and the blade 3 is vertically positioned on the bolt 5.
In some embodiments, two or more through holes are located on a vertical line at the center of the blade 3, and two or more grooves are located on a vertical line at the center of the side wall of the blade holder 2.
In some embodiments, the tail rod 1 is connected with the blade holder 3 in a threaded manner, so that different tail rods 1 can be replaced for various types of electric drills and electric hammers.
When the tool is used, the positioning pin 4 of the tool 10 is vertically inserted into the central position of a hole to be drilled, the position of the blade 3 on the bolt 5 is adjusted according to the radius of the hole to be drilled, the tip end of the bottom of the blade 3 is positioned at the periphery of the hole to be drilled, the positioning nuts 7 on the two sides of the blade 3 are rotated, the positioning nuts 7 are close to the blade 3 and finally attached to the side wall of the blade 3, and the blade 3 is locked. And (3) inserting the tail rod 1 into an electric drill or an electric hammer, and starting a switch of the electric drill or the electric hammer to perform drilling operation.
When another hole with a different aperture needs to be drilled, the positioning nuts 7 on the two sides of the blade 3 are unscrewed firstly, so that the positioning nuts 7 are far away from the blade, when the positioning needle 4 is positioned at the center of the hole to be drilled, the blade 3 is pushed to move on the bolt 5, and finally the tip end of the bottom of the blade 3 is positioned on the periphery of the hole to be drilled. The positioning nuts 7 on both sides of the blade 3 are rotated again so that the positioning nuts 7 are close to the blade 3 and finally abut against the side wall of the blade 3 to lock the blade 3 in position. And starting the electric drill or the electric hammer switch again to perform the drilling operation.
The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
