Detailed Description
Detailed description of the preferred embodiment 1
As shown in fig. 1-2, an adjustable nail ejecting tool comprises a nail ejecting screw rod and a nail ejecting support 5; a screw threaded hole 4 is formed in the middle upper part of the top nail support 5, a spring support threaded hole 6 is formed below the screw threaded hole 4, spring supports 9 are distributed in the spring support threaded hole 6, threads are arranged on the peripheries of the spring supports 9, and a non-circular insertion hole 9-1 is formed in the middle shaft of each spring support; the non-circular jack 9-1 is triangular, quadrangular, trapezoidal or internal hexagonal and the like, and is mainly used for driving the spring support 9 to rotate together through the rotation of the top nail screw rod without obstructing the free up-and-down movement of the top nail screw rod; the upper part of the top nail screw is also provided with a top nail head 1 in a shape of a nearly cone, and the lower part of the top nail head 1 is an outer hexagon head 2. The lower part of the threaded rod of the top nail threaded rod is also combined with a spring stop dog 7 and a linkage inserted rod 8; the linkage inserted bar 8 is matched with the non-circular jack 9-1 and can freely move up and down through the non-circular jack; an upper top spring 10 is arranged between the spring support 9 and the spring stop 7. The cross section of the linkage inserted bar 8 is correspondingly triangular or quadrangular or trapezoidal or hexagonal. The lower end of the threaded hole 6 of the spring support in this embodiment is of an open structure.
Specific example 2
This embodiment differs from the embodiment 1 only in that: support balance springs 11 are further distributed below the spring support 9, the support balance springs 11 are always in an upward jacking state relative to the spring support 9, the upward jacking springs 10 are large in elasticity and correspond to the weight of the linear guide rail to select when in use, and the support balance springs 11 are arranged to prevent the spring support 9 from being extruded by the upward jacking springs 10 to be too large to be beneficial to rotating operation. And a rotary gasket 13 is also arranged between the support balance spring and the spring support. The lower end of the threaded hole 6 of the spring support of this embodiment is detachably provided with a tightening cap 12.
When using, only need rotate as required and adjust outer hexagonal worker portion 2, the elastic extrusion force of spring 10 that pushes up that all can receive to set for regardless of rotatory rising or descending to which height of top screw, effectively prevent because the rotatory regulation that vibration leads to the top screw to be connected and appear with the thread with top screw support 5 when thread wearing and tearing or machine inspection from stopping unstable phenomenon such as the retraction that appears at once, provide the force guarantee for guaranteeing high accuracy assembly of high accuracy linear guide. This embodiment is favorable to improving the smoothness nature of the rotatory operation of top nail screw rod through being equipped with support balance spring 11.
