[0007] Further, the split clamping plate is connected with the hollow plug through the insertion strip, and the insertion strip is fastened with the hollow plug through the fastening screw.
[0008] Further, the split clamping plate is connected with the hollow plug through the insertion strip, and the insertion strip is fastened with the hollow plug through the fastening screw.
[0009] Further, the small frame body is provided with mounting holes around, and the mounting holes at both ends of the small frame body are fastened with the split clamping plate through the countersunk screw.
[0010] Further, the small frame clamp is arranged in the inner part of the opposite face of the two large frame clamps, and the large frame clamp is abutted with the outer wall of the small frame clamp through the inner recess of the opposite face under the driving of the two air cylinders.
[0011] Compared with the prior art, the utility model has the advantages of the following:
[0012] 1、 the utility model discloses in using, first via big frame fixture to fix small frame fixture, and the small frame fixture is inserted in the recessed notch of the opposite surface of both sides big frame fixture and is fastened through both sides air cylinder extrusion, secondly via small frame fixture to fix small frame body, and the small frame body is adhered in the lower recess of the opposite surface of both sides separation type clamping plate and is fastened through countersunk screw, and further realize the conversion of the mesh frame specification, and the design of separation type clamping plate makes the separation type clamping plate slide connection through the insertion strip and the hollow insert block, and further insertion strip is fastened through the abutment of fastening screw and hollow insert block, and through the telescopic adjustable structure design of above-mentioned, the small frame fixture can adjust with the size of small frame body, and the practicality is stronger.
