[0002] When the paint inspection and testing laboratory conducts operations, it often faces the situation that the sizes and materials of the containers provided by suppliers are different. Especially affected by transportation, storage and other links, some reactions such as oxygen consumption occur inside the paint, resulting in a decrease in internal pressure. The laboratory has a single way to open the container, uneven types of utensils, and consumes a lot of time. Especially for containers sealed with plastic racks, using a utility knife to open the can poses a safety problem.

[0003] Some paints need to be inspected for sag resistance according to the GB / T 9264 standard. In actual operation, it is difficult to control the smooth operation of the sag tester, which easily causes waste of test plates, bending of paint films, and uneven thickness of each paint film, seriously affecting the actual judgment and easily leading to deviation of test results.

[0004] Some paints need to be sampled using a wet film applicator, such as JT / T 280-2022, HG / T 5176-2017, etc. In actual operation, it is difficult to apply uniform pressure to the wet film applicator, which easily causes a certain error in the thickness of the paint film on the surface of the test plate and easily contaminates the test bench and the operator's hand surface with paint.

[0005] Some paints need to be sampled using a wire bar, such as GB / T 9756-2018, etc. In actual operation, it is difficult to apply uniform pressure to the wire bar, which easily causes uneven coating on the surface of the test plate.

[0006] Based on this, in the laboratory inspection link, how to quickly and safely open the paint container, how to improve the effective utilization rate of laboratory utensils, and how to conveniently use the sag tester, wet film applicator, and wire bar. Therefore, a multifunctional portable wrench for laboratories is needed. Content of the Utility Model

[0007] The main purpose of the utility model is to provide a multifunctional portable wrench for laboratories, which can effectively solve the problems in the background art.

[0008] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0009] A multifunctional portable wrench for laboratories includes a handle, a gripper, a wing bolt, a triangular knife-shaped mold, and a square-shaped mold. The gripper is in a gate shape. A stud is fixedly installed at the top of the horizontal end of the gripper. A threaded hole is opened in the middle of the vertical end of the gripper. The handle is threadedly connected to the stud. The stud of the wing bolt passes through the threaded hole and is threadedly connected to the triangular knife-shaped mold or the square-shaped mold.

[0010] Preferably, the handle is made of hardwood, and the outer surface of the handle is wrapped with an anti-slip rubber sleeve to ensure a large frictional force between the handle and the palm. A screw hole adapted to the stud is provided at the bottom of the handle.

[0011] Preferably, both the triangular knife-shaped mold and the square-shaped mold are made of hard metal materials, and screw holes adapted to the studs of the butterfly bolts are provided on both the triangular knife-shaped mold and the square-shaped mold. A round hole is provided outside the square-shaped mold.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] The present utility model discloses a multifunctional portable wrench for laboratories. By assembling the handle and the gripper, a longer force-bearing rod is obtained, which is convenient for prying open barrels and cans that are difficult to open. By installing adjustable molds at the end of the gripper, it can be applied to multiple scenarios, such as tightening butterfly bolts for pressing a sagging meter and a wet film applicator, which can efficiently and conveniently solve many inconvenience problems during the use of equipment. By installing a triangular knife-shaped mold, various sealing strips can be safely cut open. By installing a square-shaped mold, it is more convenient to apply pressure to control the film coating of the wire bar. BRIEF DESCRIPTION OF THE DRAWINGS
