It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc. The place where the construction work is done is called "construction site" or "construction site", also called construction site.

[0003] In the process of construction, a variety of tools are needed, and a wrench is one of them. A wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts and other threaded fasteners that hold the opening or hole of a bolt or nut. Wrenches are usually made of structural steel made of carbon or alloy materials.

[0004] During construction, a wrench is a tool that workers need to carry with them, but the handle of the wrench is long, which makes it impossible for the wrench to be put into a tool box or a worker's pocket. Utility Model Content

[0007] The other end of the first holding rod is connected to the first rotating shaft, the other end of the second holding rod is connected to the second rotating shaft, an adapter block is connected between the first rotating shaft and the second rotating shaft, a fixed clip is inserted into the interior of the second holding rod, a rack is connected to the side surface of the fixed clip, a bearing is installed inside the second holding rod, a rotating rod passes through the interior of the bearing, a gear plate is connected to the surface of the rotating rod, a knob is connected to the end of the rotating rod, a positioning through hole is opened inside the adapter block, and a fixing groove is opened inside the first holding rod.

[0008] In order to realize the rotation of the first gripping rod, as a preferred embodiment of the foldable simple wrench for construction of the utility model, the first gripping rod forms a rotating structure through the first rotating shaft and the adapter block.

[0009] In order to realize the rotation of the second gripping rod, as a preferred embodiment of the foldable simple wrench for construction of the utility model, the second gripping rod forms a rotating structure through the second rotating shaft and the adapter block.

[0010] As a preferred embodiment of the foldable simple wrench for construction of the utility model, a rotating structure is formed between the rotating rod and the bearing.

[0011] In order to facilitate the movement of the fixed clamping strip by rotating the gear plate, as a preferred embodiment of the foldable simple wrench for construction of the utility model, a meshing structure is formed between the gear plate and the rack.

[0012] In order to achieve the position fixation of the first gripping rod and the second gripping rod, as a preferred embodiment of the foldable simple wrench for construction of the utility model, the cross-sections of the positioning through-hole and the fixing groove match the cross-section dimensions of the fixing clip.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model can rotate the knob in the reverse direction when the wrench is not in use, and the reverse rotation of the knob can drive the rotating rod to rotate in the reverse direction, and the reverse rotation of the rotating rod can drive the gear plate to rotate in the reverse direction, and the reverse rotation of the gear plate can drive the fixed clip to slide in the direction away from the fixed groove through the rack. When the completely fixed clip moves to the inside of the second gripping rod, the first gripping rod and the second gripping rod can be rotated at this time. The first gripping rod and the second gripping rod can be folded after being rotated 90 degrees respectively, so that the length of the wrench can be reduced, thereby making it convenient to place the wrench in a small tool box or put it into a worker's pocket.
