One end of the blade is connected to the shank, and the other end of the blade is a drill tip. The blade is provided with two spirally symmetrical chip grooves along its length. The drill tip has two main flank faces and two secondary flank faces. In the two secondary flank faces and any main flank face, the main flank face intersects with a secondary flank face to form a center line. The main flank face also intersects with another secondary flank face to form a transverse edge. Any chip groove intersects with the main flank face on the same side to form a first main cutting edge and a second main cutting edge that are staggered with each other.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0032] See also Figures 1 to 5 The embodiment of the utility model provides a disassembly and clamping mechanism for a PCB drill bit, comprising: a telescopic rod 1 and an adjustment structure 5. A connector 3 is provided at the upper end of the telescopic rod 1. The connector 3 is connected to the telescopic rod 1 by means of the adjustment structure 5. The end of the connector 3 away from the telescopic rod 1 is fixedly connected to a fixing ring 2. The arc surface of the fixing ring 2 is provided with a fixing structure 4. The upper end of the telescopic rod 1 is provided with an adjustment structure 5.

[0033] In the embodiments of the present invention, please refer to Figure 2 and Figure 3The fixed structure 4 includes four connecting rods 405, and the four connecting rods 405 are divided into a group of two. The two groups of connecting rods 405 are fixedly connected to the fixing ring 2, and the end of each group of connecting rods 405 away from the fixing ring 2 is fixedly connected to the connecting frame 404, the upper end of the connecting frame 404 is fixedly connected to the fixing plate 406, and the inner wall of the fixing plate 406 is slidably connected to two sliding rods 407, and the lower end of the sliding rod 407 is fixedly connected to the card plate 410, and the arc surface of the sliding rod 407 is covered with a spring 411, and the two ends of the spring 411 are fixedly connected to the fixing plate 406 and the card plate 410 respectively. The inner walls on both sides of the fixing ring 2 are slidably connected with several slides 402, and several slides 402 are slidably connected to the connecting frame 404. The upper surface of the slide 402 is provided with several slots 403, which are adapted to the card plate 410. When the PCB drill needle needs to be installed, the slide bar 407 is pulled to move, and the slide bar 407 slides on the inner wall of the fixed plate 406. The slide bar 407 drives the card plate 410 to move upward and separate from the card slot 403, and then the card plate 410 drives the spring 411 to contract, and the PCB drill needle is placed in the fixed ring 2. Then the PCB drill needle is squeezed against the slide plate 402, and part of the slide plate 402 is squeezed on the inner wall of the fixed ring 2 and slides. Then the slide plate 402 slides on the inner wall of the connecting frame 404. After moving to the appropriate position, the slide bar 407 is released, and the spring 411 is stretched to drive the card plate 410 to be clamped and fixed with the card slot 403. The slide plate 402 fixes the PCB drill needle, and the upper end of the slide bar 407 is fixedly connected to the connecting rod 408, and the cross-section of the connecting rod 408 is circular. The connecting rod 408 can pull the two slide rods 407 to move simultaneously, avoiding the additional operation steps of pulling the slide rods 407 one by one. The arc surface of the connecting rod 408 is provided with a plurality of notches 409, which are evenly distributed on the connecting rod 408. The notches 409 can increase the friction between the hand and the connecting rod 408, preventing slipping when pulling the connecting rod 408. The end of the slide plate 402 away from the connecting frame 404 is fixedly connected to the anti-skid pad 401, which is a rubber pad. The anti-skid pad 401 can increase the friction between the slide plate 402 and the PCB drill needle, preventing the slide plate 402 from slipping when securing the PCB drill needle.

[0034] In the embodiments of the present invention, please refer to Figure 4 and Figure 5The adjusting structure 5 includes a connecting groove 51, which is provided on the telescopic rod 1. The inner wall of the connecting groove 51 is rotatably connected to the shaft rod 58, and the arc surface of the shaft rod 58 is fixedly connected to the connecting block 52. The connecting block 52 is fixedly connected to the connecting piece 3. The inner wall of the shaft rod 58 is slidably connected to the round rod 57. The end of the round rod 57 away from the telescopic rod 1 is fixedly connected to the knob 53. A tension spring 59 is provided inside the knob 53, and the two ends of the tension spring 59 are fixedly connected to the knob 53 and the shaft rod 58 respectively. A plurality of plug rods 55 are fixedly connected to the side of the knob 53 close to the telescopic rod 1. A plurality of jacks 56 are provided on the side of the telescopic rod 1 close to the knob 53, and the plug rods 55 are adapted to the jacks 56. When it is necessary to adjust the angle of the connecting piece 3 and the fixing ring 2 and then install the PCB drill needle, pull the knob 53 to move, the knob 53 drives the insertion rod 55 to move, and then the insertion rod 55 is separated from the socket 56, and then the knob 53 drives the spring 411 to stretch, and then the insertion rod 55 is aligned with the socket 56, and then the knob 53 is turned to drive the round rod 57 to rotate, the round rod 57 drives the shaft 58 to rotate, and the shaft 58 drives the connecting block 52 to move, and then the connecting block 52 drives the connecting piece 3 and the fixing ring 2 to move, and then the insertion rod 55 is aligned with the socket 56, and then the knob 53 is released and the tension spring 59 is contracted to drive the insertion rod 55 to be inserted into the socket 56 for fixation. The arc surface of the knob 53 is provided with a plurality of anti-slip grooves 54, and the plurality of anti-slip grooves 54 are evenly distributed on the knob 53. The anti-slip groove 54 can increase the friction between the knob 53 and the hand, preventing the knob 53 from sliding when pulling, which would make it impossible to adjust the joint 3. The round rod 57 has a circular cross-section and is made of stainless steel. The round rod 57 can limit the tension spring 59, preventing the tension spring 59 from deforming during use, thereby increasing the service life of the tension spring 59.

[0035] The working principle of the PCB drill needle disassembly and clamping mechanism provided by the present invention is as follows: when the PCB drill needle needs to be installed, the slide bar 407 is pulled to move, and the slide bar 407 slides on the inner wall of the fixed plate 406, and the slide bar 407 drives the clamping plate 410 to move upward and separate from the clamping slot 403, and then the clamping plate 410 drives the spring 411 to contract, and the PCB drill needle is placed in the fixed ring 2, and then the PCB drill needle is squeezed against the slide plate 402, and part of the slide plate 402 is squeezed on the inner wall of the fixed ring 2 to slide, and then the slide plate 402 slides on the inner wall of the connecting frame 404. The sliding bar 407 is moved to the appropriate position, and the spring 411 is released to stretch the card plate 410 and the card slot 403 to be fixed. The slide plate 402 fixes the PCB drill needle. The connecting rod 408 can pull the two sliding bars 407 at the same time to move, avoiding the increase of operation steps by pulling the sliding bars 407 one by one. The notch 409 can increase the friction between the hand and the connecting rod 408 to avoid sliding when pulling the connecting rod 408. The anti-slip pad 401 can increase the friction between the slide plate 402 and the PCB drill needle to avoid sliding when the slide plate 402 fixes the PCB drill needle.

[0036] When it is necessary to adjust the angle of the connecting piece 3 and the fixing ring 2 and then install the PCB drill needle, the knob 53 is pulled to move, and the knob 53 drives the insertion rod 55 to move, and then the insertion rod 55 is separated from the socket 56, and then the knob 53 drives the spring 411 to stretch, and then the insertion rod 55 is aligned with the socket 56, and then the knob 53 is turned to drive the round rod 57 to rotate, and the round rod 57 drives the shaft 58 to rotate, and the shaft 58 drives the connecting block 52 to move, and then the connecting block 52 drives the connecting piece 3 and the fixing ring 2 to move, and then the insertion rod 55 is aligned with the socket 56, and then the knob 53 is released. The tension spring 59 contracts and drives the insertion rod 55 to be inserted into the socket 56 for fixation. The anti-slip groove 54 can increase the friction between the knob 53 and the hand to prevent sliding when pulling the knob 53, thereby making it impossible to adjust the connecting piece 3, and the round rod 57 can limit the tension spring 59 to prevent the tension spring 59 from deformation during use, thereby improving the service life of the tension spring 59.
