[0003] During the construction process, support frames are usually used to fix reserved holes at locations where doors and windows need to be opened. Since the sizes of door and window holes required at different locations in the building are usually different, and the size of the support frames is usually fixed, when reserving door and window holes at different locations on the same building, it is necessary to customize support frames of different sizes according to actual usage requirements, which increases the cost of construction and makes traditional support frames less applicable. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a door and window opening size control device.

One end of the bolt 29 is spirally inserted into the inner walls of the first threaded hole 27 and the second threaded hole 28. During the construction process, the support frame 1 is usually used to fix the holes required for installation at the locations where doors and windows need to be opened. According to actual usage needs, the screw hole block 22 can be manually held and screwed on the threaded rod 21 to a certain distance, so that it drives the connecting block 23 and the transverse support frame 24 to slide to a certain position at both ends in the inner wall of the longitudinal support frame 26 with the help of the connecting frame 25 to adjust the width of the transverse support. When the longitudinal height needs to be adjusted, the longitudinal support frame 26 can be manually held and its two ends can be slid up or down in the inner wall of the support frame 1 to a certain position, thereby driving one end of the connecting frame 25 to slide up or down in the inner wall of the transverse support frame 24 to a certain distance, and adjusting the height of the longitudinal support to obtain support frames 1 of different sizes, avoiding the need to customize support frames 1 of multiple sizes, thereby increasing the construction cost, and improving the adaptability of the support frame 1.
