Description

Technical Field

[0001] This utility model relates to the field of electric drill technology, and in particular to a waste splash-proof electric drill. Background Technology

[0002] Electric drills are drilling tools powered by AC mains electricity. They are a standard product among power tools and also the most in-demand power tool product. Electric drills are often used during interior decoration to make holes or grooves in walls or floors. However, when making grooves, stone chips and debris often fly out, which can easily cause accidental injury to the user. In addition, drilling is quite noisy, and prolonged drilling can damage the user's eardrums and even cause tinnitus.

[0003] In addition, the existing protective equipment is time-consuming and labor-intensive to install. During the continuous drilling process, the external equipment needs to be replaced, which is also time-consuming, labor-intensive, and difficult to operate. Moreover, the protective cover is prone to falling off due to the vibration of the electric drill during installation and use, which hinders the operation, reduces the efficiency of workers, and increases the workload of construction personnel. In this regard, we propose a waste anti-splash electric drill to solve the above problems. Utility Model Content

[0004] The purpose of this application is to provide a scrap anti-splash electric drill to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: A waste splash-proof electric drill: comprising a drill body, a drill bit connecting seat, an L-shaped mounting rod, a protective cover, and a movable cover. The drill bit connecting seat is located at the top center of the drill body. The L-shaped mounting rod is fixedly installed at the top center of the drill body by bolts. A drill bit is movably connected to the top of the drill bit connecting seat. A support rod is movably connected to the top of the L-shaped mounting rod. The protective cover is fixedly installed on one side of the bottom of the support rod by bolts. The movable cover is movably connected to the other end of the protective cover. An annular movable cavity is formed on the inner side of the protective cover. A plurality of springs are evenly installed on the protective cover at one end of the movable cavity. A spring is provided, with a limit ring fixed to the top of the spring by bolts. A movable cover is fixed to the center of one side of the limit ring by bolts. A positioning seat is fixed to the center of the top of the L-shaped mounting rod by bolts. A positioning spring is fixed to the bottom of the inner part of the positioning seat by bolts. A connecting plate is fixed to the top of the positioning spring by bolts. A T-shaped positioning post is fixed to the top of the connecting plate by bolts. A positioning plate is welded to one side of the top of the T-shaped positioning post. Several positioning rods are fixed to the bottom of one end of the positioning plate by bolts. A fixing hole is opened on the bottom side of the positioning rod on the L-shaped mounting rod, and the bottom end of the positioning rod moves in the fixing hole.

[0006] In summary, the technical effects and advantages of this utility model are as follows: 1. In this utility model, the drilling extension and retraction are achieved by the protective cover and the movable cover under the action of the movable cavity, spring and limit ring, which facilitates the protection against waste splashing and has strong protective performance. The sound-absorbing layer and dust filter on the inner side of the protective cover can reduce noise and filter dust. The structure is simple and the function is stable and powerful.

[0007] 2. In this utility model, the support cavity inside the support rod on the protective cover is inserted into the L-shaped mounting rod. Pulling the T-shaped positioning post causes the positioning spring under the connecting plate to stretch, so that the positioning hole on the support rod and the fixing hole of the L-shaped mounting rod are aligned. Releasing the T-shaped positioning post causes the positioning spring to return to its original position. The positioning hole under the positioning plate extends through the positioning hole into the fixing hole, thus achieving stable installation between the L-shaped mounting rod and the support rod. The operation is simple and convenient, the replacement is convenient, the installation and use are stable and firm, and the practical value is high. Attached Figure Description
