Description
Technical field
The utility model relates to a kind of screwdriver, specifically a kind of Telescopic screwdriver, belongs to machine tool technical field.
Background technology
As everyone knows, T-shaped screwdriver is made up of driver bit and the multiple component such as handle and connecting rod, be specially adapted to dismantle and fastening residing for the screw of the very narrow or very depths of caving in, space.
In machine work, often need to use T-shaped screwdriver to carry out dismounting and fastening to screw.In production and life, the structure of widely used T-shaped screwdriver is all generally fixing at present, dismounting and fastening cannot be carried out to the screw being in different depth position by the length of regulating connecting rod, the T-shaped screwdriver often needing workmen to carry multiple different length specification just can complete dismounting and the fastening task being in the screw of different depth position, so not only increase use cost, and increase the labour intensity of workmen, be unfavorable for increasing work efficiency.
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 Telescopic 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 Telescopic screwdriver, comprise handle, connecting rod, spring, expansion link, driver bit, trip bolt, tapped through hole, chute, chamfering, it is characterized in that: one end of described connecting rod is fixedly connected with the middle part of handle is vertical, the bottom of connecting rod is provided with tapped through hole, trip bolt is provided with in tapped through hole, spring and expansion link is provided with in connecting rod, the both sides of expansion link are provided with chute, trip bolt is through tapped through hole and embedding is arranged in the chute of expansion link both sides, the lower end of expansion link is provided with chamfering, expansion link is connected by the top of the chamfering with driver bit that are arranged on lower end.
The drift of described spring is greater than the length of described connecting rod.
The length of described expansion link is greater than the length of described chute.
The width of described chute is greater than the diameter of the screw rod of described trip bolt, and object trip bolt can be allowed to pass tapped through hole and embed be arranged in the chute of expansion link both sides.
Described trip bolt is through tapped through hole and embedding is arranged in the chute of expansion link both sides, and object prevents expansion link from coming off in connecting rod.
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.

Fig. 1 is perspective view of the present utility model.
Fig. 2 is stereochemical structure exploded perspective view of the present utility model.
In figure: 1-handle, 2-connecting rod, 3-spring, 4-expansion link, 5-driver bit, 6-trip bolt, 7-tapped through hole, 8-chute, 9-chamfering.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of Telescopic screwdriver, comprise handle 1, connecting rod 2, spring 3, expansion link 4, driver bit 5, trip bolt 6, tapped through hole 7, chute 8, chamfering 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, the bottom of connecting rod 2 is provided with tapped through hole 7, trip bolt 6 is provided with in tapped through hole 7, spring 3 and expansion link 4 is provided with in connecting rod 2, the both sides of expansion link 4 are provided with chute 8, trip bolt 6 is through tapped through hole 7 and embedding is arranged in the chute 8 of expansion link 4 both sides, the lower end of expansion link 4 is provided with chamfering 9, expansion link 4 is connected with the top of driver bit 5 by the chamfering 9 being arranged on lower end.
The drift of described spring 3 is greater than the length of described connecting rod 2.
The length of described expansion link 4 is greater than the length of described chute 8.
The width of described chute 8 is greater than the diameter of the screw rod of described trip bolt 6, and object trip bolt 6 can be allowed through tapped through hole 7 and embed be arranged in the chute 8 of expansion link 4 both sides.
Described trip bolt 6 is through tapped through hole 7 and embedding is arranged in the chute 8 of expansion link 4 both sides, and object prevents expansion link 4 from coming off in connecting rod 2.
In time needing tighten and unscrew the screw be in compared with deep location, first unclamp trip bolt 6, expansion link 4 just can stretch out connecting rod 2 under the elastic force effect of spring 3, then manual adjustments expansion link 4 stretches out the length of connecting rod 2, finally screw trip bolt 6 and can lock expansion link 4, thus reach dismounting and the fastening object being in bolt compared with deep location or nut.
In time needing tighten and unscrew the screw being in more shallow position, first unclamp trip bolt 6, expansion link 4 just can stretch out connecting rod 2 under the elastic force effect of spring 3, then manual compression by expansion link 4 enters in connecting rod 2, screw trip bolt 6 simultaneously and can lock expansion link 4, thus reach dismounting and be fasteningly in the bolt of more shallow position or the object of nut.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
