Description
Technical field
The utility model relates to a kind of instrument, particularly a kind of holding-pressing type screwdriver easy to carry, time saving and energy saving, that convenient, operating efficiency is high flexibly of mounting or dismounting screw.
Background technology
We know, screw is standard component, although screw is little, the interwoveness in the life, work of people, it is fastening that all kinds of electrical equipment, machinery, furniture etc. all need screw to carry out, 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, increase the labour intensity of operating personnel, the long-time staight shank screwdriver that uses often makes operating personnel's arm ache; Electric screw driver is time saving and energy saving, but its larger volume, heavier weight and the flying power that is limited to battery make it be difficult to meet the needs of real work.In power supply field operation personnel, need to install and remove a large amount of screws, for metrological personnel, when workload is large, every day need install and remove up to a hundred pieces of electric energy meters, and mounting or dismounting screw reaches 600 pieces, screwdriver need be used to rotate 3600 circles, if use electric screw driver to charge 2-3 time, inefficiency.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of holding-pressing type screwdriver easy to carry, time saving and energy saving, that convenient, operating efficiency is high flexibly.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of holding-pressing type screwdriver, be provided with the pistol type housing be 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 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 be 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 action button.
Gas receiver described in the utility model adopts metal gascollecting cap cylinder, and gas receiver is fixed in the cavity that barral of a gun and handle formed, to store more gases at high pressure.
Gas receiver suction nozzle described in the utility model is provided with check valve, makes the gas only import but no export in gas receiver, improves the pressure in gas receiver.
Turbine mechanism described in the utility model adopts booster-type turbine mechanism, to improve the torsion of turbine wheel shaft.
Inflator described in the utility model adopts high pressure hand inflater, as OUNAI handle type portable inflator, to increase work efficiency.
When the utility model uses, first carry out visual examination, check whether breakage and deformation situation; Press inflating bat-handle again, see that whether running is normal, with or without gas leak phenomenon and to gas receiver inflation, then driver bit is aimed at screw, makes driver bit forward or reverse by action button, realize the mounting or dismounting function of screw, the utility model replaces arm revolving force with grip, more meets body mechanics's design, have easy to operate, use light and flexible, volume little, lightweight, without the need to charging, the advantage such as easy to carry, operating efficiency is high, labour intensity is low, be applicable to all kinds of working condition.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in the figure: a kind of holding-pressing type screwdriver, be provided with the pistol type housing be 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 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 be 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 action button 9, gas receiver is adopted 3 and is used metal gascollecting cap cylinder, gas receiver 3 is fixed in the cavity that barral of a gun and handle 1 formed, 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 adopts booster-type turbine mechanism, to improve the torsion of turbine wheel shaft, inflator adopts high pressure hand inflater, as OUNAI handle type portable inflator, to increase work efficiency, when the utility model uses, first visual examination is carried out, check whether breakage and deformation situation, press inflating bat-handle again, see that whether running is normal, with or without gas leak phenomenon and to gas receiver inflation, then driver bit is aimed at screw, makes driver bit forward or reverse by action button, realize the mounting or dismounting function of screw, the utility model replaces arm revolving force with grip, more meets body mechanics's design, have easy to operate, use light and flexible, volume little, lightweight, without the need to charging, the advantage such as easy to carry, operating efficiency is high, labour intensity is low, be applicable to all kinds of working condition.
