DESCRIPTION OF THE INVENTION: TECHNICAL FIELD This invention relates to a detecting device, and more particularly to a decorative device; a detecting device for inspecting the position of the decorative object after the workpiece. [Prior Art] About 2: There are more and more decorative parts on the housing of the product, especially; clothing/decoration parts such as the peripheral mounting ring of the camera on the electronic product: the ring is usually engraved with text 'These words let the user know the information such as the pixels of the camera, and the words are generally arranged in a curved shape. However, these loops are prone to bias when placed, which affects the appearance of electronic products. These electronic products with a ring offset are bad products that need to be detected and removed. In the production of large-scale electronic products, the detection of such defective products is more versatile, and the detection device is not easy to operate, and the detection effect is not satisfactory, and it is difficult to achieve a goal of balancing production lines and increasing production capacity. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a detecting device capable of quickly detecting a misalignment of a decorative member. a detecting device for detecting a position of a decorative piece attached to a workpiece, the detecting device comprising a base and a pressing plate, wherein the pressing plate is provided with an alignment hole, and the workpiece is positioned on the base The pressing plate cooperates with the base and presses the workpiece, and the pattern on the decorative piece on the workpiece is observed through the alignment hole to determine the position of the decorative piece. Compared with the prior art, the detecting device can accurately determine whether the decorative member has a deviation position by arranging the workpiece between the base and the pressing plate, and observing the pattern of the enamel fittings 200944745 on the workpiece through the alignment holes on the pressing plate. The detecting device has the advantages of simple structure and convenient operation, and can quickly detect whether the decorative part is placed or not. [Embodiment] Referring to Figure 1, a detecting apparatus 100 according to a preferred embodiment of the present invention includes a base 10 and a pressure plate 20. The base 10 has a rectangular structure, and has a holding surface 11 . The holding surface 11 is provided with two protrusions 12 and four limiting blocks 14 . The bumps 12 have a square body structure and respectively protrude from two sides of the holding surface 11. Each of the protrusions 12 protrudes from a positioning post 122, and the positioning post 122 is a cylinder for holding the pressing plate 20. The four limiting blocks 14 are rectangularly distributed on the holding surface 11 and have a height corresponding to the height of the bumps 12. An arcuate wall 142 is formed at one corner of each of the limiting blocks 14, and each of the arcuate walls 142 is opposite to each other. The four arcuate walls 142 and the engaging surface 11 define an accommodating space 144. The accommodating space 144 is for accommodating and positioning a housing of the electronic device. The pressing plate 20 is a rectangular block having a pair of positioning holes 22 and two positioning holes 24 defined therein. The alignment hole 22 is defined between the two positioning holes 24 and has a trapezoidal shape and penetrates the pressure plate 20. The two positioning holes 24 are circular holes and are respectively formed at two ends of the pressure plate 20 for engaging with the positioning post 122. The material of the platen 20 can be made of a transparent polycarbonate (PC) material, and the bottom surface of the platen 20 is coated with black paint 26 around the alignment hole 22. Referring to FIG. 2, an electronic device housing 30 includes a main body 32 and a lens assembly 34. The lens assembly 34 is disposed on the main body 32. The lens assembly 34 includes a lens 342 and a decorative ring 344. The decorative ring 344 is disposed around the periphery of the lens 342 7 200944745 and surrounds the lens 342, and the decorative ring 344 can be fixed by bonding. A pattern 3442 is formed on the decorative ring 344, and the pattern 3442 is distributed in an arc on the annulus. Referring to FIG. 3, when the detecting device 1 of the preferred embodiment of the present invention detects the presence or absence of the deviation of the decorative ring 344 of the electronic device housing 30, the housing 30 is placed into the accommodating space 144, and the housing 30 passes through four. The limiting block 14 is positioned, and the height of the housing 30 is flush with the height of the bump 12 and the limiting block 14; then the pressing plate 20 is placed on the base 10, and the positioning hole 24 of the pressing plate 20 is inserted into the Said on the positioning post 122 of the block 12. At this point, the alignment aperture 22 will align the pattern 3442 of the decorative ring 344. The operator observes the pattern 3442 on the decorative ring 344 by viewing the bit hole 22, and when the operator can fully see the pattern 3442 of the decorative ring 344, the decorative ring 344 is affixed, if only the decorative ring 344 is visible. When the partial pattern 3442 or the whole pattern 3442 is not visible, the decorative ring 344 is misplaced, and the casing 30 can be regarded as a defective product. The pressure plate 20 is made of polycarbonate material, and the surface of the penetrating pressure plate of the working environment is coated with the black paint © 26 on the bottom surface of the pressure plate 20 so as to be in sharp contrast with the pattern 3442 on the decorative ring 344. It is advantageous for the operator to identify the position of the pattern 3442 of the decorative ring 344. The detecting device 1〇〇 is disposed between the base 1〇 and the pressing plate 20, and the positioning hole 122 of the base 10 cooperates with the pressing plate and the positioning hole 24 and passes through the matching hole on the pressing plate 20% The position comparison with the figure t 3442 of the garnish ring 344 on the casing 3 is performed, and the decorative ring 344 can be sufficiently judged whether there is a deviation. The detection device 1 is simple in structure, convenient in operation, and accurate in judgment.
