Description
Technical Field
The embodiment of the invention relates to the technical field of screwdrivers, in particular to an anti-electricity practical screwdriver with auxiliary control.
Background
A screwdriver is a tool used to turn a screw to force it into place, typically having a thin wedge-shaped head that is insertable into a slot or recess in the screw head, mainly in both a straight (negative) and a cross (positive), and typically a hex-shaped screwdriver, including both internal and external hex-shaped.
When the meter is assembled and the power is connected to the actual operation, the screws are often required to be screwed and unscrewed, the distance between the screws is very short, error touch is easy to occur, the screws are inconvenient to fasten or loosen during one-hand operation, when one round of back hand is screwed, the tool bit is easy to jump out of the screw port, surrounding parts are caused to be mistakenly touched, and even damage or short circuit is caused to the parts, therefore, in order to ensure the accuracy of the operation, a worker often uses both hands of the screwdriver, one hand holds the screwdriver, the screwdriver is kept stable, the other hand rotates to operate, but the insulating part of the screwdriver is too short, the holding of the two hands is not facilitated, the tool handle is far away from the tool bit, the tool bit is difficult to be stabilized by one hand, the tool bit is not only laborious, and the tool bit is easy to shake, and the accurate operation is not facilitated.
Disclosure of Invention
Therefore, the embodiment of the invention provides an anti-electricity practical screwdriver with auxiliary control, which is held on an insulating sleeve rotatably connected with a metal rod and a handle by one hand, so as to solve the problem of inconvenient operation of both hands caused by limited length of the handle in the prior art.
In order to achieve the above object, the embodiments of the present invention provide the following technical solutions: the utility model provides a take auxiliary control's anti-electricity type practical screwdriver, includes handle of a knife and one end is equipped with the metal pole of tool bit, and the other end circumference fixed grafting of metal pole is in the handle of a knife, the fixed lower retainer plate that is equipped with on the metal pole, lower slider has been cup jointed in the rotation on the lower retainer plate; an upper fixing ring is fixedly arranged at the lower end of the knife handle, and an upper slide fastener is sleeved on the upper fixing ring in a rotating manner; the upper sliding buckle and the lower sliding buckle are connected through an insulating sleeve, and the upper sliding buckle and the lower sliding buckle are fixedly connected with the insulating sleeve.
Further, the outer side walls of the upper fixing ring and the lower fixing ring are respectively provided with an annular limiting chute.
Further, the inner side walls of the upper slide fastener and the lower slide fastener are respectively provided with an annular limiting slide block which is rotationally embedded in the annular limiting ring groove.
Further, a plurality of rubber strips are fixedly arranged on the outer wall of the insulating sleeve.
Further, one end of the knife handle is provided with a hook hole penetrating through two sides of the knife handle.
Further, an external standard is arranged on the knife handle.
Further, the tool bit is a magnetic tool bit.
Further, the upper fixing ring, the lower fixing ring, the upper slide fastener and the lower slide fastener are all coaxially arranged with the metal rod.
Embodiments of the present invention have the following advantages:
When the insulating rubber sleeve is used, one hand holds the insulating sleeve, the other hand rotates the cutter handle, and as the upper fixed ring fixed on the cutter handle is rotationally connected with the upper sliding buckle fixed on the insulating sleeve and the lower fixed ring fixed on the metal rod is rotationally connected with the lower sliding buckle fixed on the insulating sleeve, when the cutter handle is rotated and the metal rod is driven to rotate, the upper sliding buckle and the lower sliding buckle respectively rotate in the upper fixed ring and the lower fixed ring, so that the insulating rubber sleeve cannot rotate along with the rotation; based on the structure, when one hand turns the handle to screw the screw, the other hand can hold on the insulating sleeve to keep the whole stability of the screw driver, so that the whole screw driver is prevented from shaking when the one hand turns back after turning round, and the defect that the cutter head is easy to jump out from the screw hole due to the fact that the traditional screw driver is limited in length of the handle and inconvenient to operate by both hands is avoided; in the meter-mounting power-on operation requiring frequent screwing and unscrewing, the use of operators is greatly facilitated, the working efficiency of the operators is improved, and the operation risk of the operators is reduced.
