Miniature jack

This creation is about a miniature jack, especially a miniature jack that can hold up objects and fine-tune the support height.

The table is an indispensable tool in the high-tech industry. No matter what kind of work is done, there is always a table that can make the work more smoothly. On the contrary, if no table can be used, the difficulty of the work will increase significantly.

If the work to be performed requires high precision (such as scientific experiments), in order to prevent the work results from being affected by unnecessary changes, most users hope that the work table can be kept level to maintain the accuracy of the work; The support feet may wear out due to prolonged use or other factors, making the work table unable to maintain the level, and working on a non-level work desktop may have an impact on the accuracy of the work.

In order to restore the high precision level of the desktop, the current adjustment method is to place a horizontal measuring instrument on the desktop, and then adjust the height of the working table according to the reading of the measuring instrument, such as putting other items under the sole of any table, but because of this method The height of the item itself cannot be adjusted. If the height of the item on the pad does not match the required height, the height can only be adjusted by constantly changing the item. Therefore, it is often necessary to adjust the level of the working table to a short period of time to adjust or not. Fine-tune the height.

With regard to the above shortcomings, it is necessary to propose an improvement scheme to restore the work table to a high level of precision more efficiently and accurately when adjusting the height of the lost work table.

In order to solve the above problems, the present invention proposes a miniature jack, which can quickly and accurately perform high-precision level adjustment by a fine adjustment mechanism disposed on a micro jack.

According to the above object, the present invention provides a miniature jack comprising: a main part, comprising: a body having a hollow interior, a first hole in the top surface and a second hole in the side; and a top drill having an upper portion a rod-like structure, the rod-shaped structure passes through the first hole of the body, the lower half has a first inclined surface; and a slider has an upper half having a second inclined surface opposite to the first inclined surface and is in contact with the slide The block has a transverse through hole, and a first thread structure is formed on the inner side of the through hole; a rotating shaft portion includes: a driving shaft having a second threaded structure on one end and being combined with the first threaded structure of the slider; The knob is coupled to the other end of the drive shaft; wherein the knob rotates to drive the drive shaft to rotate, and the rotation of the drive shaft drives the slider to move back and forth by the thread, so that the second slope connects the first slope to move the top drill up and down.

A miniature jack provided by the present invention can be used to support an object that needs to be level and adjust the height of the support. When adjusting the height, the user can easily adjust the height by hand without any hand tools; and without the need of additional measuring tools, it can be accurately adjusted to the required height.
