Abstract

The present invention relates to an L-wrench drop prevention device comprising: a first body having a first upper insertion hole formed on one side; a second body coupled to the first body and having a first lower insertion hole formed on one side corresponding to the first upper insertion hole; at least one first magnet interposed on one side corresponding to the first upper insertion hole and the first lower insertion hole among the inner sides of the first body and the second body; and a hook portion formed protruding outward from one side of the outer surface of at least one of the first body or the second body and having a hook hole formed on one side thereof, wherein at least one of the first body or the second body has a first magnetic hole formed on one side of the inner surface corresponding to the first magnet so that one side of the first magnet is exposed to the outside, and a plurality of the first magnets may be installed at regular intervals along the inner circumference of the first body and the second body. According to the present invention as described above, not only can an L-wrench be easily connected to a work belt using a wire, but the wire can also be prevented from twisting during the use of the L-wrench, thereby significantly improving work efficiency.

Description

L-wrench fall prevention unit The present invention relates to an L-wrench fall prevention device, and more specifically, to an L-wrench fall prevention device that not only allows an L-wrench to be easily connected to a work belt using a wire but also prevents the wire from twisting during the use of the L-wrench, thereby significantly improving work efficiency. Generally, workers at work sites involving work at heights, such as installing signs on building exteriors or outdoor air conditioner units, carry and use various tools including spanners, wrenches, tape measures, and screwdrivers for tasks like assembling parts or finishing work. Accordingly, when working at heights, workers wear a work belt with a storage space for storing tools around their waist, but there were problems such as inconvenience when taking out or putting back tools, and if a tool was dropped due to a worker's mistake, the falling tool could cause safety accidents or damage surrounding equipment. To resolve this problem, in accordance with the Rules on Industrial Safety and Health Standards, workers prevent tools from falling by connecting them to a work belt worn on one side of the body with a wire. However, when trying to prevent a tool using a wire from falling, in the case of a tool with a loop, the tool could be simply connected and used by using a carabiner attached to the end of the wire, but in the case of an L-wrench, there was a problem in that it was difficult to connect it directly to the work belt through the wire because there was no hole or loop to attach a carabiner. In the field, to prevent L-wrench from falling, a cable tie is usually tightly fastened to one side of the L-wrench to form a loop, and a carabiner is attached to it. However, because the cable tie is tightly fastened to one side of the L-wrench, the fall prevention strap connected to the L-wrench gets twisted during use, causing a problem that interferes with the worker's work. Furthermore, when replacing an L-wrench of a different size for the next task, the cable tie attached to the L-wrench had to be cut and a new cable tie attached to the L-wrench to connect it to the work belt; this process was very cumbersome, and there was a problem that there was a risk of the L-wrench falling during the replacement.
