Hand-held self-rotated reinforcing steel bar hook

Abstract

The invention relates to a building tool, and concretely relates to a hand-held self-rotated reinforcing steel bar hook, which solves the problems that a former reinforcing steel bar hook needs to be used by shaking a wrist, and is big in operation difficulty and low in work efficiency, and realizes hand-held rotation. The hand-held self-rotated reinforcing steel bar hook provided by the invention is simple to operate and high in work efficiency, and comprises a handle, a device box, a pushing and pressing device, a rack device and a rotary device. The hand-held self-rotated reinforcing steel bar hook is characterized in that the device box is arranged at the front end of the handle; the pushing and pressing device is arranged at the upper end of the device box; the rack device and the rotary device are arranged in the device box. The rack device comprises a rack, an upper positioning block and a lower positioning block; the upper positioning block is connected to the upper end of the right end face of the rack in a welding way; the lower positioning block is connected to the lower end of the right end face of the rack in a welding way; a first oblique sliding chute is arranged at the side end face of the upper positioning block, penetrates through the front end face and the rear end face of the upper positioning block, and is arranged along a direction from the left upper corner to the right upper corner of the upper positioning block.

Description

technical field

[0001] The invention relates to a construction tool, in particular to a hand-held self-rotating steel bar hook. Background technique

[0002] Steel bar hook is a common tool for binding steel bars on construction sites, and is often used for fastening work when metal binding wires are used to bind steel bars. Existing steel bar hooks have various materials and models, but most of them are similar in structure. They are composed of handles, hook bodies and other components.

[0003] For example, the patent application number is a new type of steel hook CN201420187671.9. The steel hook includes a handle, a hook body and a fastener; the handle is a tubular structure with two ends open, and its external front end is tapered. The inner diameter of the handle is smaller than the inner diameter of the end, and the intersection of two different inner diameters forms a ring-shaped card platform, and the inner wall of the end of the handle is provided with internal th...
