DETAILED DESCRIPTION
[0021] like Figures 1-4 As shown, the utility model provides a technical solution: a drill bit that can prevent deviation, including a fixed base 1, a motor 2 is passed through the fixed base 1, and is fixedly connected at the penetration point, a twist drill 3 is fixed to the output end of the motor 2, the fixed base 1 is provided with a positioning device 4 for assisting the twist drill 3 to prevent deviation, and the positioning device 4 is provided with a protective device 5 to prevent debris from flying out and injuring people.
[0022] The positioning device 4 includes a connecting rod 41, a connecting plate 42, a spring 43, a positioning ring 44, a rivet block 45 and a positioning pin 46. The connecting rod 41 passes through the fixed seat 1 and is slidably connected at the penetration point. The connecting plate 42 is fixedly installed on the upper surface of the connecting rod 41. The connecting rod 41 slides upward to drive the connecting plate 42 to move upward. A spring 43 is fixed to the bottom surface of the connecting plate 42. One end of the spring 43 is away from the connecting plate 42 and is fixedly connected to the upper surface of the fixed seat 1. The connecting plate 42 moves upward to stretch the spring 43. The spring 43 applies tension to the connecting plate 42. The bottom surface of the connecting rod 41 A positioning ring 44 is fixed, and the positioning ring 44 drives the connecting rod 41 to slide upward. A rivet block 45 is fixed to the right end of the positioning ring 44, and the rivet block 45 fits the inner wall of the positioning ring 44. A positioning pin 46 is fixed to the bottom surface of the positioning ring 44, and the positioning pin 46 drives the positioning ring 44 to move upward. At the same time, the positioning pin 46 is more stably stuck in the positioning position due to the tension applied by the spring 43. The positioning device 4 can use the positioning pin 46 for positioning around the twist drill 3, avoiding the twist drill 3 from generating large friction or resistance, causing the twist drill 3 to deviate from the predetermined drilling path, etc., resulting in deviation.
[0023] The above-mentioned protective device 5 includes a first hinge block 51, a second hinge block 52, a first hinge rod 53, a second hinge rod 54, a slider 55, a protective plate 56 and a guide groove 57. The first hinge block 51 is fixedly installed on the upper surface of the positioning ring 44. The positioning ring 44 moves upward, driving the first hinge block 51 to move upward. The bottom surface of the fixed seat 1 is fixed with the second hinge block 52. The first hinge block 51 is hinged with the first hinge rod 53. When the first hinge block 51 moves upward, it drives the first hinge rod 53 to move upward and rotates around the hinge of the first hinge block 51 and the first hinge rod 53. The second hinge block 52 is hinged with the second hinge rod 54. The end of the first hinge rod 53 away from the first hinge block 51 and the end of the second hinge rod 54 away from the second hinge rod 54 are hinged. The rotation of the first hinge rod 53 drives the second hinge rod 54 to rotate around The second hinge rod 54 rotates at the hinge of the second hinge block 52, and the first hinge rod 53 and the second hinge rod 54 are hinged at the hinge of a slider 55. The hinge of the first hinge rod 53 and the second hinge rod 54 moves outward with the rotation of the two sets of hinge rods, driving the slider 55 to move outward. The slider 55 slides with a protective plate 56, and the slider 55 drives the protective plate 56 to move outward to avoid collision between the protective plate 56 and the fixed seat 1. The protective plate 56 is provided with a guide groove 57, and the outer wall of the slider 55 is in contact with the inner wall of the guide groove 57. The protective plate 56 contacts the drilling surface and slides upward relative to the slider 55 along the guide groove 57 under the thrust of the drilling surface. The protective device 5 can protect the four sides of the twist drill 3 during drilling to avoid debris generated during drilling from splashing and injuring people, causing accidents, and at the same time will not affect the normal operation of the twist drill 3.
[0024] Working principle: First, locate around the place where the hole needs to be drilled according to the proportion, insert the rivet block 45 into the positioning ring 44, insert the positioning pin 46 into the positioning point, start the motor 2, and the motor 2 drives the twist drill 3 to drill. As the depth of the drilling becomes deeper, the positioning pin 46 moves upward relative to the twist drill 3, and the positioning pin 46 drives the positioning ring 44 to move upward. The positioning ring 44 drives the connecting rod 41 to slide upward, and the connecting rod 41 slides upward to drive the connecting plate 42 to move upward, stretching the spring 43. The spring 43 applies tension to the connecting plate 42, so that the positioning pin 46 is more firmly fixed in the positioning position.
[0025] The positioning ring 44 moves upward, driving the first hinge block 51 to move upward. When the first hinge block 51 moves upward, it drives the first hinge rod 53 to move upward and rotates around the hinge of the first hinge block 51 and the first hinge rod 53. The rotation of the first hinge rod 53 drives the second hinge rod 54 to rotate around the hinge of the second hinge rod 54 and the second hinge block 52. The hinge of the first hinge rod 53 and the second hinge rod 54 moves outward with the rotation of the two sets of hinge rods, driving the slider 55 to move outward. The slider 55 drives the protective plate 56 to move outward to avoid collision between the protective plate 56 and the fixing seat 1. At the same time, the protective plate 56 contacts the drilling surface and slides upward relative to the slider 55 due to the thrust of the drilling surface.
[0026] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
