Description

A kind of connecting rod extension type screwdriver
Technical field
The utility model relates to a kind of screwdriver, and specifically a kind of connecting rod extension type 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.
Be incorporated herein the applicant 201320741284.0 patent, which disclose a kind of connecting rod extension type box spanner, although this patent discloses a kind of can dismounting and is in the bolt of different depth position or the box spanner of nut with fastening, but this patent does not record a kind of screwdriver can tightened and unscrew the screw being in different depth position, be therefore necessary to provide a kind of screwdriver can tightened and unscrew the screw being in different depth position.
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 connecting rod extension type 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 connecting rod extension type screwdriver, comprise handle, connecting rod, spring, slide block, screw rod, adjusting nut, driver bit, it is characterized in that: one end of described connecting rod is fixedly connected with the middle part of handle is vertical, the inside of connecting rod is provided with spring, slide block and screw rod, screw rod is provided with adjusting nut, one end of spring is fixedly connected with the middle part of handle is vertical, the other end is fixedly connected with one end of slide block, the other end of slide block is fixedly connected with one end of screw rod, the other end of screw rod is fixedly connected with the top of driver bit.
The length of described connecting rod is greater than the drift of described spring.
The length of described connecting rod is greater than the length of described screw rod.
The length of described screw rod is greater than the drift of described spring.
Be provided with hollow structure in described connecting rod, in the hollow structure of connecting rod, be provided with spring, slide block and screw rod.
The length of described slide block is greater than the height of described driver bit.
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.
