Novel folding screwdriver

Abstract

The invention discloses a novel folding screwdriver. The novel folding screwdriver comprises screwdriver shells, fixing pieces, fixing shafts, screwdriver heads, retaining rings, screwdriver head groove pieces, driving lock pieces, driving lock piece fixing pieces, a rotating shaft, a manual stirring wheel and a cam piece. The novel folding screwdriver is simple in structure and convenient to use and carry. The screwdriver head groove pieces are welded to the retaining rings, and the manual stirring wheel is rotated with the hand, so that the rotating shaft and the cam piece are driven to rotate, and the driving lock pieces or locking parts are clamped in clamping grooves of the screwdriver head groove pieces. The screwdriver heads are fixed at a certain angle, and it is avoided that the screwdriver heads go back to a screwdriver handle along an original path due to uneven force exerting, the kinds of the screwdriver heads are multiple, the screwdriver heads are different in specification and replaceable and can be fixed at multiple angles, applicability is higher, and use is more convenient.

Description

technical field [0001] The invention relates to a hardware tool, in particular to a novel folding screwdriver. Background technique [0002] As a commonly used hardware tool, the screwdriver brings great convenience to people's life and work, saves labor costs and improves labor efficiency. According to the shape of the head of the screwdriver, the screwdriver can generally be divided into a screwdriver and a Phillips screwdriver. In daily work and life, people will choose what kind of screwdriver to use according to the shape of the screw head. [0003] The earliest screwdrivers were single screwdrivers made according to different models and specifications, which caused a large number of screwdrivers of different models and specifications to be carried during work, which was troublesome to use. At present, there are many kinds of combined screwdrivers on the market, which are equipped with different types of cutter heads. When using them, select the appropriate cutter head...

Problems solved by technology

[0003] The earliest screwdrivers were single screwdrivers made according to different models and specifications, which caused a large number of screwdrivers of different models and specifications to be carried during work, which was very troublesome to use

At present, there are many kinds of combined screwdrivers on the market, which are equipped with different types of cutter heads. When using them, select the appropriate cutter head and install it according to the needs. When using it, it is troublesome to replace the cutter head, and it is easy to lose and the cutter head is easy to loosen. , and it is easy to drop the cutter head into the working environment due to misoperation when changing the head, especially in the maintenance of electromechanical equipment, the dropped cutter head will short-circuit the components on the circuit board, resulting in huge economic losses

In order to overcome this shortcoming, someone has designed a screwdriver with a knife head and a handle connected together. When in use, the different knife heads on the handle are used to adjust the knife head to be used, but the knife head cannot be used. If it is fixed, the cutter head may be folded back to the handle through the original path due to uneven force, which is more troublesome to use and reduces the versatility

Since the cutter head cannot be fixed at a certain fixed position, the force should not be too large when screwing the screw, resulting in the screw not being tightened or unloaded, and sometimes even hurting the hand or causing an accident
