Description

Screw detacher

Technical Field

The utility model relates to the technical field of manual tools, in particular to a screw stripper.

Background

When the equipment is maintained, the mounting screw cannot be smoothly taken down due to rusting for many years or thread glue adhesion, and the screw groove is easy to slip when the screw is screwed down by a manual screwdriver.

The nail ware of getting that commonly uses on the market now has two kinds, one kind is the impact screwdriver, adopts screwdriver head cooperation circulator, and the head is criticized to the circulator installation screw during the use, and vertical alignment screw smashes the circulator with the hammer, and the circulator converts the vertical dynamics of hammer into the rotatory dynamics in twinkling of an eye, realizes the screw function of unscrewing. The impact screwdriver has poor effect and is not easy to succeed generally, and the vibration of a hammer can damage equipment. The impact screwdriver has prominent defects. Firstly, when the hammer is used for hammering, reverse elasticity can be generated, the contact between the screwdriver head and the screw is not tight, so that the screw is taken out unsuccessfully, and the screw groove is knurled; secondly, the force is not easy to master when hammering, the force is too light, the rotating force is small, the screw cannot be rotated, the device is damaged due to too heavy force, the internal parts of the device are damaged, and particularly, the shell is damaged when the device meets a plastic shell or a metal thin-wall shell; thirdly, the strength of the impact screwdriver is not easy to master, so that a skilled worker is required to operate the impact screwdriver during use, the requirement on the user capacity is high, and the impact screwdriver is not suitable for mass users; fourthly, the impact screwdriver uses hammering force to generate nail pulling effect, the requirements on manufacturing materials and processes are high during production, and otherwise the impact screwdriver is damaged after being hammered for several times.

The other type is to use a reverse screw tap, apply force by an electric drill, punch a hole from a nail head, and screw down by using the reverse force of the screw tap. The nail extractor utilizes the electric mechanical force and the torque force of the screw tap, has good nail extracting effect, but needs professional operation, and otherwise can cause injury to personnel or thread injury.
