Description:
FIELD 
     The subject matter herein generally relates to a cross-cut tester, and in particular to a cross-cut tester for adhesion testing of decorative painted film. 
     BACKGROUND 
     A cross-cut tester is mainly used to test an adhesion of decorative painted films. The cross-cut tester can carve crosswise on the surface of the film along vertical and horizontal directions, and the film can form many separate grids. A piece of tape can be covered over the separate grids, and the tape is quickly pulled up. The adhesion of the film can be determined by the number of the grids peeling off the film.

     DETAILED DESCRIPTION 
     It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure. 
     Several definitions that apply throughout this disclosure will now be presented. 
     The term “outside” refers to a region that is beyond the outermost confines of a physical object. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that the term modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like. 
       FIG. 1  illustrates an embodiment of a cross-cut tester  100 . The cross-cut tester  100  can include a handle  10 , a plurality of gaskets  20 , a plurality of blades  30 , and a position limiting frame  40 . The handle  10  can be substantially hollow and columnar. The gaskets  20  can be received in the handle  10 . A portion of the blades  30  can be received in the handle  10 . The blades  30  and the gaskets  20  can be alternately positioned one-by-one. The position limiting frame  40  can be positioned at one end of the handle  10 , and can prevent the blades  30  from moving. The blades  30  can be fixed in the handle  10  with a first screw  51 . The gaskets  20  can be fixed in the handle  10  with a second screw  52 . The position limiting frame  40  can be fixed in the handle  10  with a third screw  53 . A distance between the blades  30  can be the same, and the cross-cut tester  100  can draw many uniform lines at one time. 
       FIG. 2  illustrates that one end of the first screw  51  (as shown in  FIG. 1 ) can be locked by a nut  54 . Thus, the blades  30  can be detachably mounted in the handle  10 . One end of the second screw  52  (as shown in  FIG. 1 ) can be locked by a nut  55 . Thus, the gaskets  20  can be detachably mounted on the handle  10 . 
       FIG. 3  illustrates that at least one groove  11  can be defined in one end of the handle  10  which can be sealed. A blunt part of the blades  30  (as shown in  FIG. 1 ) can be positioned in the groove  11 , and can be broken by the groove  11 . A receiving cavity  12  can be defined in the handle  10 . The receiving cavity  12  can be configured to receive the gaskets  20  (as shown in  FIG. 1 ) and the blades  30 . The other end of the handle  10  can define an obliquely arranged opening  121 . An oblique angle of the opening  121  can be the substantially the same as an angle of a front end of each blade  30 . The handle  10  can further include a first sidewall  13  and a second sidewall  14 , and the first sidewall  13  and the second sidewall  14  are relatively arranged. 
     A position of the first sidewall  13  adjacent to the opening  121  can define a screw hole  15 , the third screw  53  can be screwed into the handle  10 , and can be resisted against the position limiting frame  40 . A through hole  16  can be defined in a position of the handle  10  away from the opening  121 . The through hole  16  can pass through the first sidewall  13  and the second sidewall  14 . The through hole  16  can include a resisting portion  161 . The resisting portion  161  can be located in the through hole  16  adjacent to the receiving cavity  12 . The resisting portion  161  can be substantially a ring, and can be configured to resist against the first screw  51  (as shown in  FIG. 1 ). A substantially long sliding groove  17  can be defined in a substantially central position of the handle  10 . An edge of the sliding groove  17  can include a resisting portion  171 . The resisting portion  171  can be located in the sliding groove  17  adjacent to the receiving cavity  12 . The resisting portion  171  can be substantially ring shaped, and can be configured to resist against the second screw  52  (as shown in  FIG. 1 ). The second screw  52  can resist against the different positions of the sliding groove  17 . 
       FIG. 4  illustrates that each gasket  20  can be substantially a parallelogram. One end of the gasket  20  can include a bevel  21 , and a shape of the bevel  21  can be the same as a shape of the front end of the blade  30 . The other end of the gasket  20  can define a fixing hole  22 . The first screw  51  (as shown in  FIG. 1 ) can pass through the fixing hole  22  to fix the gasket  20  in the handle  10 . A substantially central position of the gasket  20  can define a fixing groove  23 . A shape of the fixing groove  23  can be substantially the same as a shape of the sliding groove  17  (as shown in  FIG. 3 ). The second screw  52  (as shown in  FIG. 1 ) can pass through the fixing groove  23 , and the blades  30  can be fixed to the different positions of the fixing groove  23 . 
       FIG. 5  illustrates that each blade  30  can be substantially a parallelogram. The blade  30  can include a plurality of creases  31 . When the blade  30  is blunt, the blunt part of the blade  30  can be easily broken along the creases  31 . One end of the blade  30  can define a fixing hole  32 . The second screw  52  (as shown in  FIG. 1 ) can pass into the sliding groove  17  (as shown in  FIG. 3 ), the fixing groove  23  (as shown in  FIG. 4 ) and the fixing hole  32 , and can pass through the other sliding groove  17 . Thus, each gasket  20  can resist against each blade  30 , and the blades  30  can be fixed between the gaskets  20 . 
       FIG. 6  illustrates that the position limiting frame  40  can include a first plate  41 , a second plate  42 , and a third plate  43 . The second plate  42  and the third plate  43  can extend along a vertical direction of the first plate  41 . The first plate  41 , the second plate  42  and the third plate  43  can combine to form a front opening  44  and a back opening  45 . An oblique angle of the front opening  44  can be the substantially the same as an angle of the opening  121  (as shown in  FIG. 3 ). A size of the front opening  44  can be smaller than a size of the back opening  45  to prevent the blades  30  (as shown in  FIG. 5 ) from moving. Thus, lines drawn by the blades  30  can be equal. The position limiting frame  40  can be mounted in the opening  121 , and the first plate  41  can be attached to the second sidewall  14  (as shown in  FIG. 3 ). The third screw  53  (as shown in  FIG. 1 ) can pass through the screw hole  15  (as shown in  FIG. 3 ) and resist against the blades  30  and the gaskets  20  (as shown in  FIG. 1 ) to the first plate  41 . Thus, the blades  30  can be partly and steady surrounded by the position limiting frame  40 . A standard width of each blade  30  can be about 9.0±0.1 mm, and the width of some blades  30  can be about 9.24 mm. Therefore, a width of the front opening  44  can be 9.12 mm or 9.26 mm allowing the blade  30  be held in the position limiting frame  40 . 
     The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a cross-cut tester  100 . Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, especially in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
