Description

Technical Field

[0001] The utility model relates to a flat drill, in particular to an enhanced impact-resistant flat drill. Background Art

[0002] A flat drill is a drilling tool consisting of a handle and a flat drill bit. In order to accurately locate the hole, a positioning drill is set at one end of the flat drill bit. Due to its advantages of simple manufacturing and low cost, it is widely used in the processing of small holes with a diameter of less than 1 mm. For example, in the flat drill disclosed in application No. 202222623351.0, a conical screw head is used as a positioning head. During the drilling process, the threaded head is low in strength and weak in impact resistance, which can easily cause damage to the drill bit, thereby delaying the processing progress;

[0003] In addition, the flat drill bits currently on the market are usually set to be uniform in thickness and flat, which makes the flat drill bits unable to withstand large impact forces. Therefore, during the drilling process, the flat drill bits are easily damaged, thereby affecting the drilling efficiency. Utility Model Content

[0004] In order to solve the problems in the related art, the present application provides an enhanced impact-resistant flat drill, which solves the problem that the flat drill has low strength and is not impact-resistant during the drilling process, thereby affecting the drilling efficiency.

[0005] The technical solution is as follows:

[0006] A reinforced impact-resistant flat drill comprises a shank and a cutting head with overlapping longitudinal axes, the cutting head comprising a positioning head and a flat drill bit, and the flat drill bit is characterized in that the flat drill bit is fixedly connected to one end of the shank, the positioning head comprises a straight piercing cone installed in the middle of the other end of the flat drill bit; the flat drill bits on both sides of the shank are thick at both ends and thin in the middle.

[0007] Through the above technical solution, by setting the straight piercing cone, the strength and impact resistance of the positioning head can be improved, ensuring the smooth progress of drilling, thereby ensuring the drilling efficiency;

[0008] By making the flat drill bit thick at both ends and thin in the middle, the impact force can be dispersed to the wider areas at both ends during the drilling process, avoiding the concentration of impact force at a single point, thereby reducing the risk of the flat drill bit breaking. The thicker design at both ends can provide better impact resistance, thereby extending the service life of the flat drill bit and expanding the scope of use of the flat drill.

[0009] Preferably, the flat drill bits are centrally symmetrically arranged along the longitudinal axis of the shank;

[0010] The upper end surface and the lower end surface of the flat drill bit are both arranged in an inwardly concave shape;

[0011] The left end face and the right end face of one end of the flat drill bit connected to the straight piercing cone are both arranged in an inclined shape, and the two side faces of the flat drill bit arranged in an inclined shape are arranged in parallel.

[0012] Preferably, anti-slip grooves are provided on the outer periphery of the handle.

[0013] Through the above technical solution, by setting the anti-slip pattern, the friction between the user's hand and the handle during drilling can be improved, thereby preventing the handle from accidentally slipping or losing control during use, thereby ensuring the safety of the flat drill.

[0014] Preferably, the handle portion comprises a first handle rod and a second handle rod which are concentrically fixedly arranged, the second handle rod is arranged at an end of the first handle rod away from the straight piercing cone, and the diameter of the second handle rod is smaller than the diameter of the first handle rod.

[0015] Through the above technical solution, by setting the first handle rod and the second handle rod of different diameters, the smaller second handle rod is more suitable for the user to hold firmly, avoiding loss of control of the handle during the drilling process, and the thicker first handle rod can more stably control the rotation of the flat drill bit, thereby ensuring stability and safety during the drilling process.

[0016] In summary, the beneficial effects of an enhanced impact-resistant flat drill are:

[0017] 1. The setting of the straight piercing cone can improve the strength and impact resistance of the positioning head, ensure the smooth progress of drilling, and thus ensure the drilling efficiency; by making the flat drill bit thick at both ends and thin in the middle, the impact force can be dispersed to the wider areas at both ends during the drilling process, avoiding the concentration of single-point impact force, thereby reducing the risk of flat drill bit breakage, and the design of thicker ends can provide better impact resistance, thereby extending the service life of the flat drill bit and expanding the scope of use of the flat drill;

[0018] 2. The anti-slip pattern can improve the friction between the user's hand and the handle during drilling, thereby preventing the handle from accidentally slipping or losing control during use, thereby ensuring the safety of the flat drill; by providing the first handle and the second handle with different diameters, the smaller second handle is more suitable for the user to hold firmly, thereby preventing the handle from losing control during drilling, and the thicker first handle can more stably control the rotation of the flat drill bit, thereby ensuring stability and safety during drilling.

[0019] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of devices and methods consistent with some aspects of the utility model as detailed in the attached claims.

[0025] In a possible embodiment, as shown in the attached Figure 1-2 As shown, an enhanced impact-resistant flat drill comprises a shank 1 and a cutting head 2 whose longitudinal axes overlap, and an anti-slip pattern is arranged on the outer periphery of the shank 1; the anti-slip pattern can increase the friction between the user's hand and the shank 1 when drilling, thereby preventing the shank 1 from accidentally slipping or losing control during use, thereby ensuring the safety of the flat drill;

[0026] The handle 1 includes a first handle rod 11 and a second handle rod 12 which are concentrically fixed. The second handle rod 12 is arranged at an end of the first handle rod 11 away from the straight piercing cone. The diameter of the second handle rod 12 is smaller than the diameter of the first handle rod 11. The smaller second handle rod 12 is more suitable for the user to hold it firmly to avoid losing control of the handle 1 during the drilling process. The thicker first handle rod 11 can more stably control the rotation of the flat drill bit 22, thereby ensuring stability and safety during the drilling process.

[0027] The cutting head 2 includes a positioning head 21 and a flat drill bit 22. The flat drill bit 22 is fixedly connected to one end of the handle 1. The positioning head 21 includes a straight spike cone installed in the middle of the other end of the flat drill bit 22. The straight spike cone can improve the strength and impact resistance of the positioning head 21, ensure smooth drilling, and thus ensure drilling efficiency.

[0028] The flat drill bits 22 on both sides of the handle 1 are thick at both ends and thin in the middle; the flat drill bits 22 are centrally symmetrically arranged along the longitudinal axis of the handle 1; the upper end face and the lower end face of the flat drill bit 22 are both inwardly concave; the left end face and the right end face of one end of the flat drill bit 22 connected to the straight piercing cone are both inclined, and the two side faces of the inclined flat drill bit 22 are parallel; during the drilling process, the impact force can be dispersed to the wider areas at both ends to avoid the concentration of single-point impact force, thereby reducing the risk of breakage of the flat drill bit 22, and the thicker design at both ends can provide better impact resistance, thereby extending the service life of the flat drill bit 22 and expanding the scope of use of the flat drill. Because the flat drill bit 22 and the positioning head 21 are strong and impact-resistant, more wood boards with greater hardness can be drilled.

[0029] Working principle: When drilling, the positioning head 21 is placed where the hole needs to be drilled, and the user holds the second handle rod 12 and starts to rotate it, so that the handle 1 rotates, and then the flat drill bit 22 rotates to complete the drilling of the wood.

This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art that are not present in the present invention. The specification and examples are intended to be exemplary only, and the true scope and spirit of the present invention are indicated by the appended claims.

[0031] It should be understood that the present invention is not limited to the precise structure described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present invention is limited only by the appended claims.
