Description

Technical Field

[0001] The utility model belongs to the technical field related to drill needles, and particularly relates to a micro drill needle structure. Background Art

[0002] Micro drills are very fine tools, mainly used for drilling holes in tiny parts such as printed circuit boards (PCBs). The diameter of the drill can reach 0.01 mm or even thinner, which is equivalent to one-seventh the diameter of a hair. The manufacture of micro drills requires extremely high precision processing capabilities, because their size is very small and requires a microscope to see clearly, but it still has the following disadvantages in actual use:

[0003] When the micro drill is working, the corresponding drill is directly installed under the driving structure, and then the corresponding structure is installed in a suitable position. However, due to the small diameter of the drill, the drill handle needs to be carefully aligned with the installation structure during installation, and care should be taken not to damage the drill. The operation is relatively troublesome and inconvenient to use.

[0004] When the micro drill is working, it is directly installed in a suitable position through the tool handle, and is installed between the rotating structure during operation. The slender tool handle needs to be aligned with the upper installation structure. The installation operation takes a long time and is not convenient to use. Utility Model Content

[0009] Furthermore, a mounting ring is fixed at the edge of the upper part of the peripheral side of the connecting column, and mounting holes are opened through the mounting ring in a ring-shaped array. Mounting bolts are inserted into the mounting holes, and the mounting bolts are threadedly connected in the fixing column. When the connecting column is working, the mounting bolts are movably connected through the mounting holes on the mounting ring, and after the mounting bolts are inserted into the mounting holes, they are screwed into the fixing column on the connecting column, so that the fixing column and the connecting column are installed together when working.

[0010] Furthermore, a movable hole is provided at the center of the bottom end of the mounting rod, and a movable opening is provided in the mounting rod at the top of the movable hole. When the mounting rod is working, the plug rod is movably connected through the movable hole, and the socket is movably connected through the movable opening.

[0011] Furthermore, the insertion rod is movably connected in the movable hole, the mounting block is movably connected in the movable opening, the clamping bolt extends into the movable opening, a socket is provided in the mounting block, and the clamping bolt is inserted into the socket. When the insertion rod is working, it is inserted into the movable hole through the mounting block, and after the clamping bolt is screwed into the mounting rod, it enters the movable hole, so that the insertion rod is installed on the mounting rod during work.

[0012] Furthermore, the bottom end of the insertion rod extends out of the bottom end of the mounting rod, and a drill bit is fixed to the bottom end of the insertion rod, so that when working, the drill bit can be rotated to provide a hole-opening function for the workpiece.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem of inconvenience in replacing the drill needle when the micro drill is working by providing the mounting rod and the insertion rod. When the insertion rod is working, firstly, the mounting block is inserted into the movable hole at the bottom end of the mounting rod, and the insertion rod is pushed upward until the mounting block enters the movable opening, and then the clamping bolt is screwed into the mounting rod and then enters the insertion hole on the mounting block, so that the insertion rod is installed in the mounting rod. When it is necessary to remove the insertion rod from the mounting rod, the clamping bolt is inserted into the clamping bolt through the hexagonal wrench, and then the clamping bolt is rotated to leave the insertion hole on the mounting block, so that when working, the insertion rod is pulled to draw the insertion rod and the mounting block out of the movable hole on the mounting rod, the removal of the drill bit is completed, a new drill bit, the insertion rod, etc. are selected, and the above-mentioned installation steps are repeated to complete the replacement of the drill bit, and the replacement of the drill needle is more convenient.
