Abstract

The utility model relates to a powerful instrument of twisting screw soon. The problem to be solved is that the background technology exists: the screw is rusted and cannot be detached without being screwed by manpower or an electric screwdriver, the working environment for screwing the screw is narrow, and the hand or the electric screwdriver cannot enter for operation. The technical key points for solving the problem are as follows: the upper part of the outer body is provided with a slide bar, the slide bar is provided with a gravity hammer which slides up and down, the top of the slide bar is provided with a stop block, the outer body is internally sleeved with an inner body, the inner body is provided with a rotating pin column of which the top end is provided with a screwdriver head, and the oblique bottom edge arranged on the lower part of the outer body and the outer edge of the rotating pin column form a tangent structure. The screw fastening device is suitable for strongly fastening or detaching screws.

Description

Tool for strongly screwing screw

The technical field is as follows: the utility model relates to a special tool, in particular to a tool for strongly screwing a screw, which is suitable for fastening or disassembling the screw.

Background art: the existing tools for screwing the screw are manual screwdrivers or electric screwdrivers, which can fasten or dismount the screw under common operating conditions. But when under certain special conditions, such as: the screw is rusted and cannot be detached without being screwed by manpower or an electric screwdriver, the working environment for screwing the screw is narrow, and the hand or the electric screwdriver cannot enter for operation. There is no easy, effective tool to handle each time this situation is encountered.

The utility model has the following contents: the utility model aims at providing a powerful instrument of twisting screw soon to solve the background art and exist: the screw is rusted and cannot be detached without being screwed by manpower or an electric screwdriver, the working environment for screwing the screw is narrow, and the hand or the electric screwdriver cannot enter for operation. The technical scheme for solving the technical problem is as follows: a tool for strongly screwing a screw is characterized in that a slide rod is arranged at the upper part of an outer body, a gravity hammer which slides up and down is arranged on the slide rod, a stop block is arranged at the top of the slide rod, an inner body is sleeved in the outer body, a rotating pin column with a screwdriver head at the top end is arranged on the inner body, and a tangent structure is formed between the inclined bottom edge arranged at the lower part of the outer body and the outer edge of the rotating pin column. The inclined direction of the inclined bottom edge arranged at the lower part of the outer body inclines downwards from left to right or from right to left. The bottom of the inner body is connected with a fixed cone.

The utility model discloses with the more beneficial effect who has of background art be: owing to adopt above-mentioned technical scheme, it is unable to dismantle by manpower or electric screwdriver revolves soon to get into the screw rust when meetting, perhaps the operational environment who revolves the screw is narrow, and staff or electric screwdriver can't get into and use when operating the utility model discloses, fixed awl and places such as ground or wall of hookup bottom the endosome are fixed, get into screwdriver head screw top ditch inslot again, hold the gravity hammer with the hand and slide from top to bottom at the slide bar, slide at every turn and will hit the slant base that power transmission set up for the ectosome lower part through the ectosome, because the slant base that ectosome lower parts set up forms tangent structure with rotatory round pin post outer fringe for rotatory round pin post is hit at every turn and is all received instantaneous heavy hitting and rotate, and the screwdriver head that drives the top revolves and revolves. The inclined direction of the inclined bottom edge arranged at the lower part of the outer body inclines downwards from left to right to produce clockwise screwing for fastening the screw, and the inclined direction inclines downwards from right to left to produce anticlockwise screwing for detaching the screw. Like this, changed and twisted the mode of screw application of force and atress soon, showing and having strengthened the dynamics of twisting soon, use when the screw rusts and leans on manpower or electric screwdriver to twist soon motionlessly the utility model discloses complete can make things convenient for effectual dismantlement, also can be narrow at the operational environment who twists the screw, the environment that staff or electric screwdriver can't get into is convenient to operate effectively.

Description of the drawings: fig. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows: referring to fig. 1, a tool for strongly screwing a screw is characterized in that a slide rod 2 is arranged at the upper part of an outer body 4, a gravity hammer 3 which slides up and down is arranged on the slide rod 2, a stop block 1 is arranged at the top of the slide rod 2, an inner body 6 is sleeved in the outer body 4, a rotating pin 8 with a screwdriver bit 9 at the top end is arranged on the inner body 6, and a slant bottom edge 5 arranged at the lower part of the outer body 4 forms a tangent structure with the outer edge of the rotating pin 8; the inclined direction of the inclined bottom edge 5 arranged at the lower part of the outer body 4 is inclined downwards from left to right or inclined downwards from right to left; the bottom of the inner body 6 is connected with a fixed cone 7.
