Description
Technical field
The present invention relates to a kind of screwdriver, specifically a kind of screw suitable for full material screw with storage staple cartridge
Knife.
Background technology
During daily power construction, through commonly used instrument during screwdriver, tightened in order to facilitate installation, now
The general all bands of screwdriver be magnetic.But nonetheless, the non-magnetic feelings of screw are run into unexpectedly in the work progress of reality
Condition.At this moment screw can only be buttressed on the other hand, fastened on the other hand with screwdriver, but due to power construction during, in general
For installing space all than narrow, this just brings inconvenience to construction.
For this problem, the patent of Patent No. 201610369413.6, which discloses one kind, can clamp any material screw
Screwdriver, although the screwdriver can accommodate the screw of any material, so as to do not needed during fastening one it is hand steered
Firmly screw, but still have unhandy problem, because needing to lift chuck during use and can press from both sides
Tight screw, therefore during being fastened to screw, described chuck needs to be raised always, especially screw fastens
Former circles (now screw not yet connects reliably), and chuck is carried while rotation screw knife, is for workmen
Inconvenient operation.
In addition, the problem of inconvenient also is being deposited in the prevalence of screw during daily construction, the typically meeting in construction
The screw of a variety of different sizes is needed, and these screws are typically all to concentrate when being placed in a receiver, in the mistake used
Needed in journey as needed from the screw of different size.For veteran old employee, naked eyes can be passed through sometimes
Judge, but it is relatively difficult for new employee.Even by the bolt sorting placement of different size, but for
Can not be for the screw of magnetic conduction, even if any material can be clamped using one kind disclosed in the patent of Patent No. 201610369413.6
The screwdriver of matter screw, two hands are also required in the process for most starting to get up screw clamping to complete, singlehanded can not complete, effect
Rate is low.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of screwdriver suitable for full material screw with storage staple cartridge, should
