Abstract

The invention relates to the technical field of a box staff and specifically relates to a foldable box staff for construction. The foldable box staff comprises a ruler cover and a ruler bar; the rulerbar is moveably connected in the ruler cover; a fixed head is integrally connected with the right end of the ruler cover; a screw knob is in rotatable connection with the right side of the front endof the ruler cover through a rotating shaft; a rotary connecting rod is in rotatable fit with the rear end of the screw knob through the rotating shaft; a screw rod penetrating through the fixed headis in rotatable fit with the rotary connecting rod through the rotating shaft at the rear end of the screw knob. According to the foldable box staff for construction, when the box stall needs to be fixed, the connecting rod is driven to move by rotating the screw knob so that the screw rod can be moved rightwards. The screw rod is capable of changing the pressure in a hollow block and a moveable rod is capable of moving with the change of the pressure in the hollow block, so that pressure can be applied to the interior of the hollow block by moving the screw rod rightwards, the pressure in thehollow block can be increased and a fine push rod and a thick push rod can be driven to move by the moveable rod.

Description

technical field [0001] The invention relates to the technical field of tower rulers, in particular to a folding tower ruler for construction. Background technique [0002] The tower ruler is a kind of leveling ruler. Most of the early leveling rulers were made of wood, and later they were gradually made of light and high-strength materials such as aluminum alloy. Raise, the length is generally 5m, just shrink it when carrying it, because its shape is similar to a tower, so it is often called a tower ruler. [0003] However, the existing tower ruler is difficult to fix when measuring on the construction site, so that users need to find other fixing devices to fix the tower ruler, which makes it inconvenient for users to carry out measurement work, and today's tower ruler is not in use. When it is difficult to fold it, it is inconvenient for the user to carry it, causing the user to be too tired when carrying it. Contents of the invention [0004] The object of the present...
