[0002] A drilling mechanism is a general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object through rotary cutting or rotary extrusion. It is also called a drilling rig, punching machine, eyelet drilling machine, through-hole machine, etc.

[0003] Chinese patent CN220636383U discloses a high-precision drilling mechanism, including a workbench, a positioning assembly is arranged above the workbench, the positioning assembly includes two slide rails fixedly installed on the top of the workbench, a bearing plate is slidably connected between the opposite sides of the two slide rails, a fixed box is fixedly installed on the left and right sides of the top of the bearing plate, and a fixed screw is rotatably connected between the left and right side walls of the inner cavity of the two fixed boxes. The high-precision drilling mechanism can position the material when drilling the material by setting the positioning assembly, avoiding the material from being offset during drilling, resulting in low drilling accuracy of the material, or even damage to the material. At the same time, the drilling position of the material can be adjusted by the positioning assembly, further increasing the drilling accuracy of the material, and greatly increasing the practicality of the drilling mechanism.

[0004] The above patent improves the shortcomings of the drilling mechanism in the prior art, which has relatively low accuracy when drilling materials, resulting in the material being easily offset during drilling, reducing the accuracy of the material and causing damage to the material. However, this patent is not convenient for controlling the depth of the hole within an appropriate range during use, resulting in insufficient drilling accuracy. Utility Model Content

[0009] The beneficial effect of adopting the above further solution is that the connection plate can be limited by the limiting rod, so as to improve the stability of the connection plate when it is lifted or lowered.

[0010] Furthermore, an anti-drop plate is fixedly installed at the bottom of the limiting rod, and the anti-drop plate is circular in shape.

[0011] The beneficial effect of adopting the above further solution is that the anti-slip plate is provided to prevent the limit rod from separating from the connecting plate.

[0012] Furthermore, the inner shape of the sleeve and the outer shape of the adjusting block are both rectangular, and the inner surface of the sleeve and the outer surface of the adjusting block are in sliding contact.

[0013] The beneficial effect of adopting the above further solution is that the adjusting block and the drill rod can be limited in a rectangular shape by the sleeve, and the adjusting block can be easily moved in the sleeve.

[0027] The drill rod length adjustment mechanism includes an adjustment block 9 movably installed inside the sleeve 7. The internal shape of the sleeve 7 and the external shape of the adjustment block 9 are both rectangular. The inner surface of the sleeve 7 and the outer surface of the adjustment block 9 are in sliding contact. The sleeve 7 can limit the rectangular position of the adjustment block 9 and the drill rod 8, and it is convenient for the adjustment block 9 to move inside the sleeve 7. A rectangular cavity 10 is opened inside the adjustment block 9, and a tension spring 11 is fixedly installed inside the rectangular cavity 10. A pull rod 12 that penetrates the outer surface of the sleeve 7 is fixedly installed at one end of the tension spring 11. A strip hole 18 is opened on the surface of the sleeve 7, and the pull rod 12 is located at the strip hole. In the strip hole 18, the surface of the pull rod 12 is in sliding contact with the inner surface of the strip hole 18, which is convenient for the pull rod 12 to move on the sleeve 7.
