V-shaped angle rotary type ice surface drilling device

Abstract

The invention relates to a V-shaped angle rotary type ice surface drilling device, which is characterized in that an axilla pressing frame, a first vertical grab handle, a second vertical grab handle, a worm and wall cutting knives serve as a main body; a pair of knife handles which are opened in a V shape is arranged at the bottom of a right-angle positioning frame, and a transverse fixing column and a transverse fixing sleeve which are fixedly connected with the knife handle are arranged at the bottom of each knife handle; T-shaped sliding blocks capable of sliding up and down in hollow-out sliding ways are arranged in the knife handles, and the T-shaped sliding blocks are connected with the right-angle positioning frame through hinges; and the wall cutting knives fixedly connected with the knife handles are arranged on the lower side surfaces of the knife handles, and drilling knives fixedly connected with the wall cutting knives are arranged at the bottoms of the wall cutting knives. The V-shaped angle rotary type ice surface drilling device can limit the included angle between the knife handles through self-locking of a screw and a fixing nut to drill holes of different sizes to meet the requirements of a fisherman, and is ingenious in design and convenient to operate; and the knife handles can be expanded and contracted at two ends of the right-angle positioning frame, so that the device can be carried by the fisherman conveniently and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of fishing equipment, in particular to a V-shaped angle rotary ice surface drilling device. Background technique [0002] Winter fishing is also called ice fishing. It is a special fishing method in winter. However, in the north, the ice usually freezes when winter comes. Bait fishing and other work. [0003] At present, it is limited to manual work such as breaking holes and drilling holes with ice tools, or now there are some mechanical, such as electric or diesel engines, gasoline engines, etc., to drive drill bits and other drilling work. Most of the drilling ice-breaking drill bits used Twist drill type drills are used to mechanically break the ice, but the use of the above-mentioned tools makes people's work huge and low in work efficiency. At the same time, equipment such as electrical energy and other mechanical energy consumes high energy and costs high. [0004] And it is not easy to carry, which...

[0003] At present, it is limited to manual work such as breaking holes and drilling holes with ice tools and the like, or now there are some mechanical, such as electric or diesel engines, gasoline engines, etc., to drive drill bits and other drilling work. Most of the drilling ice-breaking bit systems used Twist drills are used to mechanically break the ice, but the use of the above-mentioned tools makes people's work huge and low in work efficiency. At the same time, equipment such as electrical energy and other mechanical energy consumes high energy and costs high

[0004] And it is not easy to carry, which has caused great troubles for ice fishing anglers
