Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, fig. 2 and fig. 3, the utility model provides a take auxiliary control's electricity-proof type practical screwdriver, handle of a knife 1 and one end including installing external standard 13 are equipped with the metal pole 3 of tool bit 2, and the fixed grafting of other end circumference of metal pole 3 is in handle of a knife 1, fixed retainer plate 4 down that is equipped with on the metal pole 3, it has cup jointed down the thread slipping 5 to rotate on the retainer plate 4 down, the fixed retainer plate 6 that is equipped with of lower extreme of handle of a knife 1, it has cup jointed the thread slipping 7 to rotate on the upper retainer plate 6, go up the thread slipping 7 and connect through insulating boot 8 between the thread slipping 5 down, just go up thread slipping 7 and lower thread slipping 5 all with insulating boot 8 fixed connection, go up retainer plate 6, lower retainer plate 4, go up thread slipping 7 and lower thread slipping 5 all with the coaxial setting of metal pole 3.

Specifically, when the screwdriver is used, one hand holds the insulating sleeve 8, and then adjusts the metal rod 3 to enable the screwdriver head 2 to be aligned to a screw hole of a screw to be screwed and to be connected with the screw in a circumferential matching manner; then the other hand holds the knife handle 1, when the other hand rotates the knife handle 1, because the upper fixing ring 6 fixed on the knife handle 1 is rotatably connected with the upper slide fastener 7 fixed on the insulating sleeve 8, and the lower fixing ring 4 fixed on the metal rod 3 is rotatably connected with the lower slide fastener 5 fixed on the insulating sleeve 8, when the knife handle 1 is rotated and the metal rod 3 circumferentially and fixedly connected with the knife handle 1 is driven to rotate, the upper slide fastener 7 and the lower slide fastener 5 respectively rotate in the upper fixing ring 6 and the lower fixing ring 4, so that the insulating rubber sleeve 8 cannot rotate along with the rotation.

When a screw is screwed by rotating the tool holder 1 by one hand, the other hand can be held on the insulating sleeve 8 to keep the whole stability of the screwdriver, so that the phenomenon that the whole screwdriver shakes when the one hand rotates for one circle and then returns is avoided, and the phenomenon that the tool bit 2 jumps out of a screw hole is avoided. The insulating sleeve 8 is arranged to facilitate holding of the other hand, so that the problems that a tool bit is easy to jump out of a screw during one-hand operation and the metal rod 3 is easy to touch by mistake during two-hand operation to cause electric shock in the traditional screwdriver due to the limited length of the tool handle 1 are solved; in the dress table that needs frequent screw up and loosen the screw connects the electricity operation, made things convenient for operating personnel's use greatly, avoided operating personnel mistake to touch metal pole 3 and take place the electric shock accident to and avoid tool bit 2 to jump out of the screw mouth and lead to damaging potential safety hazards such as components and parts and circuit, improved operating personnel's work efficiency, reduced operating personnel's operational risk.

Preferably, all be equipped with annular spacing spout 9 on the lateral wall of going up retainer plate 6 and retainer plate 4 down, all be equipped with the annular spacing slider 10 of embedding in annular spacing spout 9 of rotating on the inside wall of going up slider 7 and lower slider 5, through the cooperation of annular spacing spout 9 and annular spacing slider 10, carry out axial spacing to insulating boot 8, prevent that it from taking place to slide and lead to going up slider 7 and last retainer plate 6 and lower slider 5 and the cooperation of retainer plate 4 to become invalid.

Preferably, the fixed axial is provided with a plurality of rubber strip 11 on the outer wall of insulating cover 8, and outstanding rubber strip 11 is favorable to operating personnel to grip, and has increased the gas permeability of hand, has improved the travelling comfort that operating personnel gripped.

Preferably, the upper end of handle of a knife 1 is equipped with the couple hole 12 that runs through 1 both sides of handle of a knife, can wear into in the couple hole 12 and hang articles such as rope, couple, and bind with operating personnel through articles such as hanging the rope, thereby make things convenient for operating personnel to place the screwdriver in operation process, avoid the screwdriver to drop, especially at high altitude construction and operating space narrow and small, when operating personnel is not convenient for place the screwdriver, it can be used for preventing that the screwdriver from dropping and be used for hanging and place the screwdriver to hang the rope, and is both convenient, trouble and danger that the screwdriver drops and brings have also been avoided.

Preferably, tool bit 2 is the magnetism tool bit, and when the screw hole is darker, still be located the screwed hole after the screw is twisted out, inconvenient taking out, and then can be with the screw suction through tool bit 2 that has magnetism, and when twisting shorter screw, inconvenient taking the screw and holding, accessible magnetic tool bit 2 comes the screw to absorb and fixes, has improved the convenience of operating personnel operation greatly.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
