Problems solved by technology

[0003] (1) When a screw that needs to be screwed in or out requires a large torque, it is necessary to hold the screwdriver handle with great strength, and apply a lot of pressure and twisting force to the screwdriver handle with the palm of the hand, which often causes the palm to be worn
[0004] (2) After a lot of force, the balance is difficult to grasp, and the screwdriver body is easy to skew, so that the screwdriver head twists the groove of the screw head, making it difficult to continue to work, causing more trouble
[0005] (3) The head part of the general screwdriver is exposed outside, which is easy to cause scratches to people and other objects, and it is inconvenient to carry

Abstract

The invention discloses an eccentric screwdriver. The eccentric screwdriver comprises a handle (1), a fixing frame (2), a groove (3) and a cutter body assembly (9). The handle (1) is annular and madeof light metal materials with high strength; the front end part of an annular ring deviates from the center to form a solid body, and the rear end of the annular ring is a semicircular hole (12); thesolid part of the annular ring is integrally formed with the fixing frame (2); the fixing frame (2) and the front end of the handle (1) are formed into the groove (3); a small shaft (14) integrated with a button (5) is arranged on the small shaft (14); the cutter body assembly (9) is arranged on the small shaft (14); and the cutter body assembly (9) can rotate around the small shaft (14), when thebutton (5) is pressed by hand, the cutter body assembly (9) can be bounced upwards and fixed, and when the button (5) is pressed again, the cutter body assembly (9) can be rotated downwards to the groove (3) and fixed. The eccentric screwdriver easily generates large torque during rotating screws, and is convenient to control and carry.

Description

technical field [0001] The invention relates to a hardware tool, in particular to an eccentric screwdriver. Background technique [0002] A screwdriver is a commonly used hardware tool, which is often used in daily work and life. A commonly used screwdriver includes a cylindrical handle and a knife body connected to the handle. axis, there are the following problems: [0003] (1) When a screw that needs to be screwed in or out requires a large torque, it is necessary to hold the screwdriver handle with great strength, and apply a lot of pressure and twisting force to the screwdriver handle with the palm of the hand, which often causes the palm to be worn . [0004] (2) After using a lot of force, the balance is difficult to grasp, and the screwdriver body is easily skewed, so that the screwdriver head twists the groove of the screw head, making it difficult to continue working, causing even greater troubles. [0005] (3) The cutter head of the general screwdriver is expos...
