Description
Technical field
The present invention relates to a kind of instrument of mounting or dismounting screw, a kind of easy to carry, time saving and energy saving, the most convenient, holding-pressing type screwdriver that work efficiency is high.
Background technology
It is understood that, screw is standard component, although screw is little, but the interwoveness in the life, work of people, all kinds of electrical equipments, machinery, furniture etc. are required for screw and fasten, tradition staight shank screwdriver is provided with handle, connecting rod and cutter head, use palpus arm rotary handle repeatedly, use and waste time and energy, inefficiency, increasing the labor intensity of operating personnel, long-time use staight shank screwdriver often makes operating personnel's arm ache；Electric screw driver is time saving and energy saving, but its bigger volume, heavier weight and be limited to the flying power of battery and make its needs being difficult to meet real work.In power supply field operation personnel, need the substantial amounts of screw of mounting or dismounting, as a example by metrological personnel, when workload is big, needing up to a hundred pieces of electric energy meters of mounting or dismounting every day, mounting or dismounting screw reaches 600 pieces, screwdriver need to be used to rotate 3600 circles, if using electric screw driver to charge 2-3 time, inefficiency.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of easy to carry, time saving and energy saving, the most convenient, holding-pressing type screwdriver that work efficiency is high.
For reaching above-mentioned purpose, the technical solution used in the present invention is:
A kind of holding-pressing type screwdriver, it is provided with the pistol type housing being made up of gun barrel and handle, it is characterized in that gun barrel leading section is provided with turbine mechanism, turbine case in turbine mechanism is connected with gun barrel inwall, turbine wheel shaft is supported on turbine case through bearing, turbine wheel shaft is provided with turbine, the front end of turbine wheel shaft is stretched out muzzle and is dialled mouth with driver bit and be connected, gas receiver it is provided with in handle, the outlet nozzle of gas receiver is connected with the air inlet of reversal valve, first gas outlet of reversal valve is connected with the rotating forward air inlet on turbine case through conduit, second gas outlet of reversal valve is connected with the reversion air inlet on turbine case through conduit, the suction nozzle of gas receiver is connected with the inflator escape pipe being fixed in handle, the inflating bat-handle of inflator is arranged on the handle front end under barral of a gun, pistol type housing is provided with reversal valve operation button.
Gas receiver of the present invention uses the gascollecting cap cylinder that metal is made, and gas receiver is fixed in the cavity of barral of a gun and handle formation, to store more gases at high pressure.
Gas receiver suction nozzle of the present invention is provided with check valve, makes the gas only import but no export in gas receiver, improves the pressure in gas receiver.
Turbine mechanism of the present invention uses booster-type turbine mechanism, to improve the torsion of turbine wheel shaft.
Inflator of the present invention uses high pressure hand inflater, such as OUNAI handle type portable inflator, to improve work efficiency.
When the present invention uses, first carry out visual examination, check whether breakage and deformation situation；Press inflating bat-handle again, see that operating is the most normal, inflate with or without gas leak phenomenon and to gas receiver, then driver bit is directed at screw, make driver bit forward or reverse by operation button, realize the mounting or dismounting function of screw, the present invention replaces arm revolving force with grip, more meets body mechanics's design, have easy to operate, use light and flexible, volume little, lightweight, without charging, the advantage such as easy to carry, work efficiency is high, labor intensity is low, it is adaptable to all kinds of working conditions.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
nullAs shown in the figure: a kind of holding-pressing type screwdriver，It is provided with the pistol type housing being made up of gun barrel 8 and handle 1，It is characterized in that gun barrel leading section is provided with turbine mechanism，Turbine case in turbine mechanism is connected with gun barrel inwall，Turbine wheel shaft is supported on turbine case through bearing，Turbine wheel shaft is provided with turbine，The front end of turbine wheel shaft is stretched out muzzle and is dialled mouth 2 with driver bit and be connected，Gas receiver 3 it is provided with in handle 1，The outlet nozzle of gas receiver 3 is connected with the air inlet of reversal valve 4，First gas outlet of reversal valve 4 is connected with the rotating forward air inlet on turbine case through conduit 5，Second gas outlet of reversal valve 4 is connected with the reversion air inlet on turbine case through conduit 5，The suction nozzle of gas receiver is connected with inflator 6 escape pipe being fixed in handle，The inflating bat-handle 7 of inflator 6 is arranged on the handle front end under barral of a gun，Pistol type housing is provided with reversal valve operation button 9，3 gascollecting cap cylinders made with metal adopted by gas receiver，Gas receiver 3 is fixed in the cavity of barral of a gun and handle 1 formation，To store more gases at high pressure，Gas receiver 3 suction nozzle is provided with check valve，Make the gas only import but no export in gas receiver，Improve the pressure in gas receiver，Turbine mechanism uses booster-type turbine mechanism，To improve the torsion of turbine wheel shaft，Inflator uses high pressure hand inflater，Such as OUNAI handle type portable inflator，To improve work efficiency，When the present invention uses，First visual examination is carried out，Check whether breakage and deformation situation；Press inflating bat-handle again, see that operating is the most normal, inflate with or without gas leak phenomenon and to gas receiver, then driver bit is directed at screw, make driver bit forward or reverse by operation button, realize the mounting or dismounting function of screw, the present invention replaces arm revolving force with grip, more meets body mechanics's design, have easy to operate, use light and flexible, volume little, lightweight, without charging, the advantage such as easy to carry, work efficiency is high, labor intensity is low, it is adaptable to all kinds of working conditions.
