[0002] After searching, application number 202220996111.2 discloses a wall leveling tool for house construction, including a leveling plate, the back of which is fixedly connected to a limiting rod; the back of the leveling plate is hinged with a fixing rod, the side of the fixing rod is fixedly connected with a reinforcing rib, the side of the reinforcing rib is slidably connected with a sliding tube, and the sliding tube is on the outside of the fixing rod, the side of the sliding tube is movably inserted with an insertion rod, the side of the insertion rod is movably sleeved with a spring, the two ends of the side of the spring are respectively fixedly connected to the side of the insertion rod and the side of the sliding tube, one end of the insertion rod is fixedly connected with a wedge block, and the side of the wedge block is provided with a slot.

[0003] During use, the wall leveling tool for house construction in this patent application moves the slide tube downward to adjust the overall length of the fixed rod and the slide tube. The user holds two wedge blocks to increase the friction between the anti-sliding block and the side of the fixed rod, thereby increasing the overall stability of the device after adjustment, making it easier for the user to level walls of different heights. However, during such use, since the device requires the user to hold two wedge blocks to enhance the stability of the overall structure of the device, the user always keeps applying force to the two wedge blocks when using the device, which makes the device more laborious to use. At the same time, it also causes the length of the slide tube to fail to be effectively utilized, reducing the practicality of the device. For this reason, we propose a wall leveling device for building construction. Utility Model Content

The leveling plate 12 is a prior art and is not described in detail. An adjusting mechanism is arranged inside the support tube 10 to drive the extension tube 11 to move up and down. The adjusting mechanism includes an adjusting threaded rod 13 rotatably connected to the center position of the bottom wall of the inner cavity of the support tube 10 and an adjusting nut block 14 threadedly connected to the outer wall of the adjusting threaded rod 13. The top end of the adjusting threaded rod 13 extends to the inside of the extension tube 11, and the adjusting nut block 14 is fixedly embedded in the bottom end of the inner cavity of the extension tube 11. Linear slide grooves 16 are symmetrically provided on the outer wall of the extension tube 11. The two linear slide grooves 16 are both slidably connected with limit slide bars 17 fixedly connected to the corresponding positions of the inner cavity side wall of the support tube 10. The top end of the adjusting threaded rod 13 is rotatably connected with a limit slide bar 17 that is in sliding contact with the inner cavity side wall of the extension tube 11. The limiting slider 18 and the bottom wall of the support tube 10 are provided with a storage card slot 23, and the bottom end of the adjusting threaded rod 13 passes through the bottom wall of the inner cavity of the support tube 10 and extends to the inside of the storage card slot 23. The inside of the storage card slot 23 is provided with an operating mechanism that drives the adjusting threaded rod 13 to rotate. The operating mechanism includes an adjusting handle 15 arranged at the bottom end of the adjusting threaded rod 13, and a square sliding hole 19 is provided at the bottom end of the adjusting threaded rod 13. A square sliding rod 20 fixedly connected to the top of the adjusting handle 15 is slidably connected inside the square sliding hole 19.
