[0023] Embodiment 1

[0024] Combined with Figure 1 and attached Figure 2 A grating ruler structure that is easy to install includes a grating ruler body 1, a detachable base plate 2 is provided on the grating ruler body 1, sleeves 7 are provided on both sides of the base plate 2, an adjustable extension plate 8 is inserted in the sleeve 7, and a locking structure is provided between the sleeve 7 and the extension plate 8.

[0025] Through the above structure, the extension plate 8 is inserted into the sleeve 7, which is convenient for flexibly adjusting the extension length of the extension plate 8. It is suitable for machine tools of different models and sizes and has strong applicability.

[0026] Combined with Figure 5 The locking structure includes a plurality of threaded holes 9 arranged on the extension plate 8, and a stud 10 extending into the threaded hole 9 is inserted on the sleeve 7, and a knob 11 is provided on the top of the stud 10.

[0027] Through the above structure, by turning the knob 11, the stud 10 is inserted into the sleeve 7 and extended into the threaded hole 9, the extension plate 8 and the sleeve 7 can be directly locked and fixed to prevent them from sliding randomly and affecting the use of the grating ruler.

[0028] Combined with Figure 1 and attached Figure 3 At least one fixing plate 3 is provided on both sides of the grating ruler body 1, and the fixing plate 3 and the base plate 2 are fixed together by locking bolts 4.

[0029] Through the above structure, the base plate 2 can be directly fixed on the grating scale, which is convenient for disassembly and assembly and is stable as a whole.

[0030] Embodiment 2

[0031] Combined with Figure 4 A vertical plate 12 is provided on one side of the extension plate 8, a limiting column 13 is inserted on the vertical plate 12, a handle 14 is provided at one end of the limiting column 13, and a spring 15 is provided on the limiting column 13 between the handle 14 and the vertical plate 12.

[0032] Through the above structure, pull the handle 14 outward, the spring 15 stretches, and the grating ruler is brought close to the machine tool. Release the handle 14, and insert it directly into the limiting holes on both sides of the machine tool through the limiting column 13, and clamp it directly on the machine tool, which is convenient for fixing the grating ruler and simple to install.

[0033] Combined with Figure 1 A threaded support column 5 is provided at the top of the bottom plate 2, a sliding block 6 is provided on the support column 5, and a groove for matching with the slide rail is provided on the sliding block 6.

[0034] Through the above mechanism, the sliding block 6 can be directly connected to the external slide rail, and the grating ruler can be used by sliding directly without being fixed, and the usage is flexible.

[0035] Combined with Figure 4 The vertical plate 12 and the limiting column 13 are both provided with a through hole 16, and the through hole 16 is provided with a thread. A threaded fixing bolt 17 is inserted into the through hole 16, and the fixing bolt 17 fixes the vertical plate 12 and the limiting column 13 together.

[0036] Through the above structure, the vertical plate 12 and the limiting column 13 can be directly fixed together to further strengthen the whole and avoid displacement of the grating scale.

[0038] The support column 5 is directly screwed onto the bottom plate 2, and the groove on the sliding block 6 can be directly plugged into the external slide rail, which is convenient for sliding the grating ruler and flexible in use.

[0039] Unscrew the support column 5, pull the handles 14 on both sides to drive the limit column 13 to move, stretch the spring 15, and move the grating ruler body 1 directly close to one side of the machine tool. Release the handle 14, and the elastic force of the spring 15 rebounds. The limit column 13 is directly inserted into the limit holes on both sides of the machine tool, and the fixing bolt 17 is continuously screwed into the through hole 16, so that the limit column 13 and the vertical plate 12 are locked together, and the whole is stable, avoiding displacement of the grating ruler and affecting its use.

[0040] Since the size and specifications of the machine tool are similar, the knob 11 is unscrewed at this time, and the extension plate 8 is pulled outward. When the extension plate 8 reaches a suitable position, the stud 10 is inserted into the sleeve 7, and the knob 11 is continuously turned to make the stud 10 continuously enter the threaded hole 9, and the extension plate 8 and the sleeve 7 are locked. This is convenient for flexible adjustment according to the size and specifications of the machine tool, and is easy to use and has strong applicability.
