Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of structure simple, easy to use, and can carry out dismantling and fastening extending screwdriver to the screw being in different depth position by the length of regulating connecting rod.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of extending screwdriver, comprise handle, connecting rod, draw-in groove, spring, slide bar, card column, through hole, circular hole, driver bit, it is characterized in that: one end of described connecting rod is fixedly connected with the middle part of handle is vertical, circular hole is provided with in connecting rod, the both sides of connecting rod are provided with draw-in groove, spring and slide bar is provided with in connecting rod, draw-in groove is provided with card column, slide bar is cylindrical structural, the upper end of slide bar is provided with through hole, is provided with card column in through hole, and slide bar is connected with the top of driver bit.
The length of described connecting rod is greater than the length of described draw-in groove.
Be provided with card column in described through hole, object coordinates draw-in groove and spring to prevent slide bar from loosening or coming off.
The length of described slide bar is greater than the length of described connecting rod.
The length of described connecting rod is greater than the drift of described spring.
After in described slide bar enters and is arranged on connecting rod circular hole, slide bar, through being arranged on the draw-in groove of connecting rod both sides and being arranged on the through hole of slide bar upper end, is fixed in connecting rod by card column.
Compared with prior art, the utility model has following beneficial effect: structure is simple, easy to use, the length of the connecting rod of T-shaped screwdriver can be regulated in a big way, thus can dismantle and the fastening screw being in different depth position, effectively reduce the quantity of the T-shaped screwdriver carried required for workmen, not only can reduce use cost, and the labour intensity of workmen can be reduced, be conducive to increasing work efficiency.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, shown in Fig. 9 and Figure 10, a kind of extending screwdriver, comprise handle 1, connecting rod 2, draw-in groove 3, spring 4, slide bar 5, card column 6, through hole 7, circular hole 8, driver bit 9, it is characterized in that: one end of described connecting rod 2 is fixedly connected with the middle part of handle 1 is vertical, circular hole 8 is provided with in connecting rod 2, the both sides of connecting rod 2 are provided with draw-in groove 3, spring 4 and slide bar 5 is provided with in connecting rod 2, draw-in groove 3 is provided with card column 6, slide bar 5 is cylindrical structural, the upper end of slide bar 5 is provided with through hole 7, card column 6 is provided with in through hole 7, slide bar 5 is connected with the top of driver bit 9.
The length of described connecting rod 2 is greater than the length of described draw-in groove 3.
Be provided with card column 6 in described through hole 7, object coordinates draw-in groove 3 and spring 4 to prevent slide bar 5 from loosening or coming off.
The length of described slide bar 5 is greater than the length of described connecting rod 2.
The length of described connecting rod 2 is greater than the drift of described spring 4.
Described slide bar 5 enters and is arranged on after in circular hole on connecting rod 28, and slide bar 5, through being arranged on the draw-in groove 3 of connecting rod 2 both sides and being arranged on the through hole 7 of slide bar 5 upper end, is fixed in connecting rod 2 by card column 6.
As shown in Figure 1, Figure 2 and Figure 7, when need dismounting and fastening be in the screw of more shallow position time, first card column 6 is upwards extracted from draw-in groove 3, rotate card column 6 makes slide bar 5 stretch out along the inwall of connecting rod 2 under the effect of spring 4 elastic force simultaneously, then manual compression by slide bar 5 enters in connecting rod 2, rotation card column 6 makes it embed in draw-in groove 3 and can lock slide bar 5 simultaneously, then embedded by driver bit 9 and need to be disassembled with in the groove of fastening screw, last turning handle 1 can carry out dismounting and fastening to the screw being in more shallow position.
As shown in Fig. 3, Fig. 4 and Fig. 8, when need dismounting and fastening be in compared with deep location screw time, first card column 6 is upwards extracted from draw-in groove 3, rotate card column 6 makes slide bar 5 stretch out along the inwall of connecting rod 2 under the effect of spring 4 elastic force simultaneously, then manual adjustments slide bar 5 stretches out the length of connecting rod 2, rotation card column 6 makes it embed in draw-in groove 3 and can lock slide bar 5 simultaneously, then embedded by driver bit 9 and need to be disassembled with in the groove of fastening screw, last turning handle 1 can carry out dismounting and fastening to being in compared with the screw of deep location.
