Description

Technical Field

[0001] The utility model relates to the technical field of drill bit positioning, in particular to a drill bit with a positioning function. Background Art

[0002] An electric drill is a drilling tool that uses electricity as power. It is a common product among power tools and also the most in-demand power tool product.

[0003] However, when people use an electric drill, they cannot position the drill bit because there are no auxiliary tools. Using the drill bit based on intuition alone can easily cause the hole to be drilled crookedly, affecting the subsequent work progress. Therefore, a drill bit with a positioning function can be used to assist the electric drill in drilling.

[0004] For this purpose, we propose a drill bit with positioning function. Utility Model Content

[0005] The main purpose of the utility model is to provide a drill bit with a positioning function. By sleeve-connecting a mounting block on the outside of an electric drill, a telescopic rod and a sleeve can be inserted into the positioning inserts at the top and bottom of the mounting block. When drilling, it is only necessary to place the positioning plate close to a wall or a board to provide a positioning function for the drill bit, thereby avoiding the hole from being skewed. In addition, the device is relatively simple to use, quick to install and disassemble, and easy to carry, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A drill bit with a positioning function comprises an electric drill, the outer side of the electric drill is sleeved with a mounting block, the top and bottom ends of the mounting block are fixedly connected with positioning plugs, the positioning plugs are provided at four locations, and the interiors of the four positioning plugs are provided with cavities;

[0008] The cavity is used for sliding installation of the movable block, and a groove is provided inside the movable block. The groove is used for installation and insertion of one end of the telescopic rod, and the cavity is also used for insertion of the sleeve.

[0009] Furthermore, the other end of the telescopic rod is movably inserted into the interior of the sleeve, and the sleeve and the telescopic rod are both provided with four points, and one end of the sleeve away from the telescopic rod is fixedly and vertically connected to one side of the positioning plate.

[0010] Furthermore, a positioning hole is provided at the center of the positioning plate, and the positioning hole is used for a drill bit to pass through, and the drill bit is rotatably mounted on one end of the electric drill.

[0011] Furthermore, a plug hole is provided on the outer side of the positioning insert, and the plug holes are provided at two locations opposite to each other, and the two plug holes are used for the limiting rod to be installed and passed through.

[0012] Furthermore, a placement groove is provided on the top of the mounting block, and the placement groove is provided at two locations, and the placement groove is used for the installation and placement of the limit rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects: by sleeve-connecting the mounting block on the outside of the electric drill, the telescopic rod and the sleeve can be inserted into the positioning inserts at the top and bottom of the mounting block, and when drilling, it is only necessary to place the positioning plate close to the wall or board to provide a positioning function for the drill bit, thereby avoiding the hole being skewed. In addition, the device is relatively simple to use, quick to install and disassemble, and easy to carry. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, a drill bit with a positioning function comprises an electric drill 1, a mounting block 2 is sleeved on the outer side of the electric drill 1, a positioning insert 7 is fixedly connected to the top and bottom ends of the mounting block 2, the positioning insert 7 is provided at four locations, a cavity 10 is provided inside the positioning insert 7 at the four locations, and a limiting ring is provided at the entrance of the positioning insert 7 to prevent the movable block 5 from sliding out of the positioning insert 7, so that the movable block 5 can only slide toward the inside of the positioning insert 7;

[0021] The cavity 10 is used for sliding installation of the movable block 5. A groove 4 is provided inside the movable block 5. The diameter of the groove 4 is smaller than the diameter of the positioning insert 7. The groove 4 is used for installing and inserting one end of the telescopic rod 13. The diameter of the telescopic rod 13 is adapted to the diameter of the groove 4. The end of the telescopic rod 13 inserted into the groove 4 can be made of magnetic material, and the movable block 5 can be made of iron. The cavity 10 is also used for inserting the sleeve 12; the other end of the telescopic rod 13 is movably plugged into the inside of the sleeve 12. The sleeve 12 and the telescopic rod 13 are both provided with four places. The end of the sleeve 12 away from the telescopic rod 13 is fixedly and vertically connected to one side of the positioning plate 11;

[0022] A positioning hole 14 is provided at the center of the positioning plate 11, and the positioning plate 11 is specifically made of transparent material. The positioning hole 14 is used for the drill bit 3 to pass through, and the drill bit 3 is rotatably installed at one end of the electric drill 1; a socket 9 is provided on the outside of the positioning tube 7, and the socket 9 is relatively provided at two locations, and the two sockets 9 are used for the limit rod 6 to pass through. There are two limit rods 6, and the insertion of the limit rod 6 can make the movable block 5 press against the entrance of the positioning tube 7, and one limit rod 6 can pass into two positioning tubes 7; a placement groove 8 is provided on the top of the mounting block 2, and the placement groove 8 is provided at two locations, and the placement groove 8 is used for the installation and placement of the limit rod 6, and the limit rod 6 pulled out of the positioning tube 7 can be placed in the placement groove 8 to avoid loss.

[0023] It should be noted that the utility model is a drill with a positioning function. When the electric drill 1 is needed to drill a hole, it is only necessary to insert the four telescopic rods 13 into the grooves 4 of the movable blocks 5 inside the respective positioning plugs 7, and allow the drill bit 3 to pass through the positioning holes 14, align the positioning holes 14 with the places where holes need to be drilled, and at the same time allow the positioning plate 11 to be close to the wall or board where holes need to be drilled and keep them parallel, thereby ensuring that the drilling direction of the electric drill 1 is vertical, start the electric drill 1 and apply pressure to the electric drill 1 to push the telescopic rod 13 into the casing 12, so that the drill bit 3 is drilled vertically into the wall or board. If the drilling depth is not enough, the limit rod 6 can be pulled out of the positioning plug 7, so that the movable block 5 can move in the positioning plug 7, and then continue to apply pressure to the electric drill 1 to push the positioning plate 11, and the casing 12 will push the movable block 5 into the interior of the positioning plug 7, thereby allowing the drill bit 3 of the electric drill 1 to drill deeper without being skewed.

[0024] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
