Description

Technical Field

[0001] This utility model relates to the technical field of hole position markers, specifically a press-type self-rotating drill hole position marker. Background Technology

[0002] To fix a device to a wall, metal plate, or other surface, one or more mounting holes need to be drilled at appropriate locations on these surfaces. If these holes are shallow through holes, the device (or its mounting bracket) can be temporarily placed on the surface, and the hole positions can be marked with a pen or drill before drilling. However, if these holes are blind holes, or hanging slots or holes that are only visible on the rear mounting surface of the device and not on the other side, the conventional marking method is to measure the relative horizontal and vertical positions of the holes on the device with a ruler, and then measure the corresponding positions of the holes on the mounting surface again with a ruler, using the edge of the device or a certain point as a reference, and then mark the holes with a pen or drill. This process is cumbersome and prone to introducing errors from multiple measurements in different directions, causing a certain deviation between the positioning marks and the actual mounting holes, affecting the positioning marking of the drilling. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a press-to-rotate drill hole position marker, which has the advantage of good hole position marking effect in narrow areas.

[0005] (II) Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a press-to-rotate drill hole position marker, including an outer cylinder, a stabilizing ring placed at the bottom of the outer cylinder, a slot formed on the outer surface of the outer cylinder, and two locking plates fixedly installed at the top of the stabilizing ring, with the two locking plates respectively locked inside the two slots.

[0007] The outer cylinder has an inner cavity inside, and the inner cylinder is placed inside the inner cavity. A miniature bearing is embedded at the top of the inner cylinder. A connecting column is fixedly installed on the inner ring of the miniature bearing. A spring is fixedly installed on the inner top wall of the inner cavity. The bottom end of the spring is fixedly connected to the top of the miniature bearing, and the spring is sleeved outside the connecting column.

[0008] A guide rod is fixedly installed at the top of the inner cylinder, and two spiral grooves are opened on the outer surface of the outer cylinder, with the two ends of the guide rod extending into the interior of the two spiral grooves respectively.

[0009] Furthermore, a fixing lug is fixedly installed at the top of the outer cylinder.

[0010] By adopting the above technical solution, a better connection can be made between the fixing ear and the mounting position on the back of the device.

[0011] Furthermore, a ring-shaped array of cutter heads is fixedly installed at the bottom end of the inner cylinder.

[0012] By adopting the above technical solution, the marking surface can be better engraved by the cutting head during positioning and marking.

[0013] Furthermore, a through hole is provided in the middle of the bottom surface of the stabilizing ring, and the diameter of the through hole is larger than the diameter of the inner cylinder.

[0014] By adopting the above technical solution, the inner cylinder and the cutter head can pass through the through hole more effectively, avoiding interference problems.

[0015] Furthermore, a second spring is fixedly installed at the bottom end of the outer cylinder, and the bottom end of the second spring is fixedly connected to the inner bottom wall of the stabilizing ring.

[0016] By adopting the above technical solution, the stabilizing ring can be reset more effectively after the pattern is drawn using a spring.

[0017] (III) Beneficial Effects

[0018] Compared with existing technologies, this press-type spin drill hole position marker has the following advantages:

[0019] This invention features a fixed lug for connection to a mounting position on a device. When marking holes, the device presses down, causing the cutting head to leave a mark at the mounting position. A stabilizing ring ensures stability on the marking surface, preventing tilting and ensuring accurate hole marking. A spiral groove and guide rod allow the cutting head at the inner cylinder's tail end to contact the marking surface when pressed. With continued pressing, the inner cylinder and guide rod move inward within the cavity, while the guide rod, guided by the spiral groove, forces the inner cylinder to rotate, thus rotating the cutting head on the marking surface for better marking. This improves the hole marking effect. Furthermore, the marking device is mounted on the back of the device; simply pushing the device in moves the marking device, avoiding the large operating clearance requirements of ordinary marking methods.
