[0002] A hexagonal shank twist drill is an electric drill bit with a hexagonal shank, resembling a screwdriver in shape, but with a helical cutting head, hence the name "twist drill". This type of drill bit is widely favored for its high-speed drilling, accurate material cutting, and high durability. After production, twist drills are generally titanium-plated to improve their strength, and a clamp is required for this process.

[0003] Existing twist drill clamps have a limited number of twist drills that can be clamped at a time, which limits their effectiveness. Furthermore, they often require manual positioning of the drill bit before clamping, which is inefficient and affects the overall clamping efficiency. Utility Model Content

The positioning block in the groove, in conjunction with a fixing spring, initially positions the drill bit. The user then slides the top seat onto the limiting rod, and after the top seat reaches a certain position, the user slides the sliding block downwards. The sliding block slides on the screw rod, compressing the spring. This movement of the sliding block drives the upper support, which in turn drives the connecting rod, which in turn drives the lower support. The lower support then drives the sliding block via the fixing rod. Once the sliding block reaches its position, it will... With the help of the fixed clamping block, the drill bit is initially clamped. Then, the user can turn the crank handle, which drives the screw to rotate. The screw rotates and drives the slider to move through the support rod. When the slider moves to a certain position, it will contact the sliding block. At this time, the slider can limit the sliding block, and the position of the sliding block is fixed. Then, with the help of the compression spring, the sliding block will be in close contact with the slider. At this time, the sliding clamping block can completely fix the drill bit. Afterwards, the user can remove the top seat from the limiting rod. This achieves the effect of fixing multiple drill bits, thus greatly improving practicality. It can also be used to position the drill bit, making it more convenient to fix it. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figures 1-5 As shown, a fixing fixture for titanium-plated hexagonal shank twist drills includes a base 1 and a top seat 2. The base 1 is provided with a positioning mechanism, which consists of a positioning component and a limiting component. The top seat 2 is provided with a fixing mechanism, which consists of a clamping component and a fixing component. The clamping component includes a sliding block 12 and multiple through holes 11. The multiple through holes 11 are all opened on the top seat 2 and are distributed at equal angles. The sliding block 12 is connected to the fixing component and is an octagonal block. The fixing component includes a screw 21 and a slider 22. The screw 21 is rotatably connected to the top of the top seat 2, the slider 22 is threadedly connected to the screw 21, and the sliding block 12 is slidably connected to the screw 21.

[0022] In use, the user can initially position the drill bit using the positioning component. Then, the top seat 2 can be connected to the limiting component. After sliding the top seat 2, the clamping component on the top seat 2 moves to a certain position. The user can then slide the sliding block 12. The movement of the sliding block 12 drives the clamping component to work, thus initially fixing the drill bit. Afterward, the user can rotate the screw 21. The rotation of the screw 21 drives the slider 22 to move. The movement of the slider 22, with the cooperation of the fixing component, fixes the position of the sliding block 12, thus completing the fixing of the drill bit. Afterward, the top seat 2 can be separated from the limiting component. This allows for the fixing and positioning of multiple drill bits, facilitating the subsequent fixing of the drill bits by the fixing component and improving practicality.

[0023] Furthermore, the clamping assembly also includes multiple fixing rods 13 and multiple lower supports 14. Each fixing rod 13 has a fixing block 15 fixedly connected to its outer end. One end of each fixing rod 13 is fixedly connected to the inner side of each through hole 11, and the other end of each fixing rod 13 is fixedly connected to each fixing block 15. Each lower support 14 has a sliding block 18 fixedly connected to its bottom. Each sliding block 18 is slidably connected to each fixing rod 13, and the position of each sliding block 18 corresponds to that of each fixing block 15. A connecting rod 16 is rotatably connected to the top of each lower support 14. An upper support 17 is rotatably connected to the end of the connecting rod 16 away from the lower support 14. The number of upper supports 17 is the same as that of lower supports 14. One end of each connecting rod 16 is rotatably connected to each lower support 14, and the other end of each connecting rod 16 is rotatably connected to each upper support 17. Multiple upper supports 17 are fixedly connected to the outside of the sliding block 12, and each upper support 17 is distributed at equal angles, so that when the sliding block 12 moves, the sliding block 12 will drive the upper supports 17 to move. The movement of the upper supports 17 will drive the connecting rod 16 to move. The movement of the connecting rod 16 will drive the lower support 14 to move. The movement of the lower support 14 will drive the sliding block 18 to move through the fixed rod 13. After the sliding block 18 moves to the position, it will initially clamp the drill bit with the cooperation of the fixed block 15.

[0024] Furthermore, the fixing assembly also includes a top plate 24, a crank handle 25, a baffle 26, a compression spring 27, and two support rods 23. One end of each support rod 23 is fixedly connected to the bottom surface of the top plate 24, and the other end of each support rod 23 is fixedly connected to the top surface of the top seat 2. Both support rods 23 are slidably connected to the slider 22, and the two support rods 23 are respectively distributed on both sides of the screw 21. The crank handle 25 is distributed on the top of the screw 21, and the crank handle 25 passes through the top plate 24 and is fixedly connected to the screw 21. The baffle 26 is fixedly connected to the screw 21, and one end of the compression spring 27 is fixedly connected to the top plate 24. The compression spring 27 is fixedly connected to the top of the baffle 26, and the other end of the compression spring 27 is fixedly connected to the bottom of the sliding block 12. The compression spring 27 is distributed on the outside of the screw 21, so that the screw 21 can be rotated by the crank 25. The rotation of the screw 21 drives the slider 22 to move through the support rod 23. When the slider 22 moves to a certain position, it will contact the sliding block 12. At this time, the slider 22 can limit the sliding block 12. At this time, the position of the sliding block 12 is fixed, and the sliding block 12 will be in close contact with the slider 22 with the cooperation of the compression spring 27, thereby improving the fixing effect.

[0025] Furthermore, the positioning component includes multiple positioning slots 31 formed on the base 1. Positioning blocks 32 are slidably connected to the inner side of the positioning slots 31, and fixing springs 33 are fixedly connected to the outer side of the positioning blocks 32. Each positioning slot 31 is distributed at equal angles, and each positioning slot 31 has the same size. The position of each positioning slot 31 corresponds to each through hole 11. Positioning blocks 32 are slidably connected to the inner side of each positioning slot 31, and fixing springs 33 are fixedly connected to the outer side of each positioning block 32. The end of each fixing spring 33 away from the fixing spring 33 is fixedly connected to the inner wall of each positioning slot 31, so that the user can place the drill bit that needs to be fixed in the positioning slot 31. At this time, the positioning blocks 32 in the positioning slot 31 will perform preliminary positioning of the drill bit with the cooperation of the fixing springs 33, thereby facilitating the subsequent clamping component to clamp the drill bit.

[0026] Furthermore, the limiting component includes a limiting rod 41 fixedly connected to the top of the base 1, a limiting plate 42 slidably connected to the limiting rod 41, a limiting spring 43 fixedly connected to the bottom of the limiting plate 42, the end of the limiting spring 43 away from the limiting plate 42 fixedly connected to the top of the base 1, and the limiting spring 43 distributed on the outside of the limiting rod 41. The top seat 2 has a round hole corresponding to the size of the limiting rod 41. The top seat 2 is inserted into the limiting rod 41 through the round hole, so that the user can slide the top seat 2 into the limiting rod 41. At this time, the limiting rod 41 can limit the top seat 2, so that the clamping component can accurately contact the drill bit in the positioning component, thereby improving the fixing effect of the drill bit.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
