[0017] The utility model has the following beneficial effects:

[0018] In the utility model, the support of multiple positioning shafts is used to make the entire tap body in a highly stable state. When the rod body rotates, the connection between the connecting ring and the connecting block and the positioning shaft allows the positioning shaft to support the rod body during downward drilling, thereby avoiding the tapping quality caused by the shaking of hand operation and improving the processing quality. At the same time, during the processing process, due to the support and positioning of the positioning shaft, the hand saves the step of constantly adjusting the position and angle of the rod body, thereby improving the processing efficiency.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-3The utility model provides an embodiment: a multi-axis positioning composite tap, comprising a rod body 1 and a plurality of positioning shafts 8, the bottom of the positioning shaft 8 is provided with an anti-slip layer to improve the stability of the overall support, the top of the rod body 1 is fixedly connected with a handle 2, the outer middle and upper side of the handle 2 is fixedly connected with a chamfering ring 3, the bottom of the rod body 1 is fixedly connected with a tap part 4, the outer periphery of the tap part 4 is evenly provided with a plurality of chip grooves 6, the bottom end of the tap part 4 is fixedly connected with a drill bit 5, the outer periphery of the positioning shaft 8 is provided with a slide groove 9 close to the rod body 1, the inside of the slide groove 9 is fixedly connected with a slide rod 10, the outside of the slide rod 10 is slidably connected with a connecting block 7, the outside of the rod body 1 is rotatably connected with a connecting ring 13, and the end of the connecting block 7 away from the positioning shaft 8 is fixedly connected to the outer periphery of the connecting ring 13. The drill bit 5 is aligned with the processing position. At this time, the bottom of the positioning shaft 8 abuts against the four sides of the workpiece to play a supporting and stabilizing role. Then the hand uses the tool to rotate and press the handle 2, driving the rod body 1 and the drill bit 5 to rotate downward. The drill bit 5 first completes the preliminary drilling, and the tap part 4 continues to probe downward for tapping. After the drilling and tapping are completed, the rod body 1 continues to probe downward. When it reaches the position of the chamfering ring 3, the chamfering ring 3 is used to further chamfer and deburr the inner peripheral edge of the hole, and finally the processing is completed. During the entire main body probing process, the connecting ring 13 moves downward, driving the connecting block 7 to slide along the outer wall of the slide rod 10 inside the slide groove 9, thereby utilizing the positioning shaft 8 to play a good supporting and stabilizing role, avoiding the shaking of the entire tap body, improving the processing quality, and the positioning shaft 8 also plays a positioning role, saving the time of continuous adjustment during the hand operation process, and improving the processing efficiency.

[0026] The rod body 1, the handle 2, the chamfering ring 3, the tap part 4 and the drill bit 5 are integrally formed, and the structure is more stable and strong, and the durability is increased. The chip groove 6 extends to the bottom of the drill bit 5, so that the debris during the drilling process can be discharged through the chip groove 6, reducing the obstruction of the debris to the drilling. The outside of the slide bar 10 is provided with a spring 12, the bottom end of the spring 12 is fixedly connected to the bottom side of the slide groove 9, and the top end of the spring 12 is fixedly connected to the bottom side of the connecting block 7. The spring 12 is used to form a support and buffering effect for the connecting block 7, further improving the overall stability. The outside of the positioning shaft 8 is slidably connected with a slip ring 11, and the slip ring 11 is fixedly connected to the side wall of the connecting block 7. The slip ring 11 is used to increase the connectivity between the connecting block 7 and the positioning shaft 8, disperse the force of the connecting block 7 on the slide bar 10, reduce friction, and extend the service life. The connecting block 7 is located above the chamfering ring 3. There are at least three positioning shafts 8, so that the support of the positioning shaft 8 is more stable.

[0027] Working principle: First, align the drill bit 5 with the processing position. At this time, the bottom of the positioning shaft 8 abuts against the four sides of the workpiece to play a supporting and stabilizing role. Then, the hand uses the tool to rotate and press the handle 2, driving the rod body 1 and the drill bit 5 to rotate downward. The drill bit 5 first completes the initial drilling, and the tap part 4 continues to probe downward for tapping. After the drilling and tapping are completed, the rod body 1 continues to probe downward. When it reaches the position of the chamfering ring 3, the chamfering ring 3 is used to further chamfer and deburr the inner edge of the hole, and finally the processing is completed. During the entire main body exploration process, the connecting ring 13 moves downward, driving the connecting block 7 to slide along the outer wall of the slide rod 10 inside the slide groove 9, thereby utilizing the positioning shaft 8 to play a good supporting and stabilizing role, avoiding the shaking of the entire tap body, improving the processing quality, and the positioning shaft 8 also plays a positioning role, saving the time of continuous adjustment during the hand operation process, and improving the processing efficiency.
