Technical Field
[0001] This utility model belongs to the technical field of drilling straightening devices, and more specifically, it relates to a hand drill drilling straightening device. Background Technology
[0002] When drilling with a hand drill, if the drill is not perpendicular to the object, it will result in an angled hole. Therefore, a device is needed to help users determine whether the hand drill is always perpendicular to the object during the drilling process, thereby ensuring the accuracy of the drilling. Utility Model Content
[0003] The present invention provides a hand drill hole correction device to solve the technical problems mentioned in the background art.
[0004] The technical solution adopted in this utility model is a hand drill hole straightening device, comprising:
[0005] A housing having a through hole for a hand drill bit to pass through;
[0006] A magnetic suction element is disposed in the through hole and is used to be attracted to the caliper used to fix the drill bit in the hand drill passing through the through hole, so that the housing can rotate synchronously with the drill bit of the hand drill.
[0007] A first laser is disposed inside the housing and can rotate with the housing. The first laser beam emitted by the first laser can penetrate the housing and irradiate the object being drilled, and the first laser beam forms an angle with the axis of the through hole.
[0008] In other words, in the hand drill hole correction device of this application, a through hole is provided on the housing, and a magnetic suction element is provided in the through hole for adhering to the caliper used to fix the drill bit in the hand drill passing through the through hole, so that the housing can rotate synchronously with the drill bit of the hand drill. A first laser is also provided in the housing. The first laser beam emitted by the first laser can pass through the housing and irradiate the object being drilled, and the first laser beam forms an angle with the axis of the through hole. If the drill bit is perpendicular to the object when drilling, the first laser beam emitted by the first laser can form a circle on the object. If the drill bit is tilted to the object when drilling, the first laser beam emitted by the first laser can form an ellipse on the object. Therefore, by judging whether the first laser beam forms a circle or an ellipse on the object, it can be determined whether the drill bit is perpendicular to the object, thereby correcting the hole and keeping the drill bit perpendicular to the object.
[0009] Optionally, the included angle allows the first laser beam emitted by the first laser to illuminate outside the vertical projection of the housing onto the object.
[0010] Optionally, the first laser is tilted within the housing.
[0011] Optionally, the magnetic suction element is a ring structure, the magnetic suction element is sleeved inside the through hole, and the magnetic suction element can be passed through by the hand drill bit.
[0012] Optionally, the magnetic element is exposed on the surface of the housing facing away from the object.
[0013] Optionally, it also includes a second laser, which is disposed inside the housing and can rotate with the housing. The second laser beam emitted by the second laser can penetrate the housing and irradiate the object being drilled, and the second laser beam is parallel to the axis of the through hole.
[0014] Optionally, the second laser is positioned near the edge of the housing.
[0015] Optionally, a light-transmitting sheet is provided on the surface of the housing facing the object, allowing the first laser beam and the second laser beam to pass through the housing.
[0016] Optionally, the surface of the housing facing the object is provided with multiple anti-collision protrusions.
[0017] Optionally, the device also includes a control board, a control switch, and a battery. The control board and the battery are disposed inside the housing. The control board is connected to the battery, the first laser, and the second laser, respectively. The control switch is disposed on the surface of the housing facing away from the object and is connected to the control board. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0029] See Figure 1 and Figure 3 A hand drill hole correction device includes a housing 100, a magnetic suction element 200, and a first laser 300.
[0030] A through hole 110 is provided through the housing 100 for a hand drill bit to pass through. It can be understood that after the hand drill bit passes through the through hole 110, it can drill a hole in the object to be drilled.
[0031] The magnetic clasp 200 is disposed in the through hole 110 and is used to attach to the caliper used to fix the drill bit in the hand drill passing through the through hole 110, so that the housing 100 can rotate synchronously with the drill bit of the hand drill.
[0032] The first laser 300 is disposed inside the housing 100. The first laser beam emitted by the first laser 300 can penetrate the housing 100 and irradiate the object being drilled, and the first laser beam forms an angle with the axis of the through hole 110.
[0033] It is understandable that when the housing 100 rotates with the drill bit, the first laser 300 inside the housing 100 can also rotate with the housing 100. When the first laser 300 rotates, the first laser beam emitted by the first laser 300 can rotate accordingly. Since the first laser beam forms an angle with the axis of the through hole 110, if the drill bit is perpendicular to the object when drilling, the first laser beam emitted by the first laser 300 can form a circle on the object. If the drill bit is tilted to the object when drilling, the first laser beam emitted by the first laser 300 can form an ellipse on the object. Therefore, it can be determined whether the drill bit is perpendicular to the object by judging whether the first laser beam forms a circle or an ellipse on the object.
[0034] It should be noted that the user can observe the light spot formed on the object by the first laser beam through the gap between the housing 100 and the object.
[0035] In other words, in the hand drill hole correction device of this application, a through hole 110 is provided on the housing 100, and a magnetic suction member 200 is provided in the through hole 110 for adsorbing the caliper used to fix the drill bit in the hand drill passing through the through hole 110, so that the housing 100 can rotate synchronously with the drill bit of the hand drill. A first laser 300 is also provided in the housing 100. The first laser beam emitted by the first laser 300 can pass through the housing 100 and irradiate the object being drilled. The first laser beam forms an angle with the axis of the through hole 110. If the drill bit is perpendicular to the object when drilling, the first laser beam emitted by the first laser 300 can form a circle on the object. If the drill bit is tilted to the object when drilling, the first laser beam emitted by the first laser 300 can form an ellipse on the object. Therefore, by judging whether the first laser beam forms a circle or an ellipse on the object, it can be determined whether the drill bit is perpendicular to the object, so that the hole can be corrected and the drill bit can be kept perpendicular to the object.
[0036] Furthermore, in order to facilitate the user's observation of the light spot formed by the first laser beam on the object, the included angle allows the first laser beam emitted by the first laser 300 to illuminate the projection of the housing 100 on the object in the vertical direction.
[0037] For example, in one embodiment, the first laser 300 may be disposed within the housing 100 at an as-slung angle as possible.
[0038] See Figure 1 The magnetic chuck 200 can be a ring structure, and can be fitted inside the through hole 110, allowing the hand drill bit to pass through. It is understood that this structure of the magnetic chuck 200 facilitates attachment to the caliper in the hand drill for securing the drill bit.
[0039] Furthermore, the magnetic clasp 200 may be exposed on the surface of the housing 100 opposite to the object. This structure allows the magnetic clasp 200 to be attracted to the metal end face of the caliper used to hold the drill bit.
[0040] See Figure 3 The hand drill hole correction device may also include a second laser 400. The second laser 400 is disposed inside the housing 100 and can rotate with the housing 100. The second laser beam emitted by the second laser 400 can pass through the housing 100 and irradiate the object being drilled, and the second laser beam is parallel to the axis of the through hole 110.
[0041] Understandably, since the second laser beam is parallel to the axis of the via 110, when the drill bit is perpendicular to the object, the second laser beam can form a circle on the object. Even when the drill bit is tilted to drill the object, the second laser beam emitted by the second laser 400 can still form a circle on the object. At this time, it can be observed with the naked eye, and the shape of the circle formed by the second laser beam on the object can be compared with the shape of the circle formed by the first laser beam on the object, i.e., whether it is elliptical. This method can help improve the accuracy of the user's judgment.
[0042] In one embodiment, the second laser 400 is positioned close to the edge of the housing 100, so that the photoelectric effect formed by the second laser beam emitted by the second laser 400 on the object can be closer to the edge of the housing 100, making it easier for the user to observe.
[0043] See Figure 2 A light-transmitting sheet 120 may also be provided on the surface of the housing 100 facing the object, allowing the first laser beam and the second laser beam to pass through the housing 100.
[0044] In one embodiment, the light-transmitting sheet 120 may have light-transmitting areas respectively provided on the emission positions of the first laser beam and the second laser beam.
[0045] See Figure 2 Multiple anti-collision protrusions 500 can be provided on the surface of the housing 100 facing the object. It can be understood that when the drill penetrates the object, the anti-collision protrusions 500 can prevent the housing 100 body from directly impacting the object and damaging the surface of the housing 100 due to human downward pressure.
[0046] See Figure 3 The hand drill hole straightening device may also include a control board 600, a control switch 700, and a battery 800. The control board 600 and the battery 800 are disposed inside the housing 100. The control board 600 is connected to the battery 800, the first laser 300, and the second laser 400, respectively. The control switch 700 is disposed on the surface of the housing 100 facing away from the object and is connected to the control board 600.
[0047] It is understood that the battery 800 can power the operation of the first laser 300 and the second laser 400, and the control switch 700 can control the operation of the first laser 300 and the second laser 400 through the control board 600.
[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of some utility models should be included within the protection scope of some utility models.
