Abstract
The utility model relates to a quick action and power saving wrench. The utility model is composed of a machine box with a box cover and a grab handle, a driving gear set which is composed of a driving shaft supported on the machine box and one shaft end of the driving shaft is stretched out of the box, a transmission shaft, a driven shaft, a driving wheel which is positioned in the machine box and is fixed on the driving shaft and a driven wheel which is engaged with the driving wheel and is fixed on the transmission shaft, a driven gear set composed of a driving wheel fixed on the driving shaft and a driven wheel which is engaged with the driving wheel and is fixed on the driven shaft, a screwed sleeve tube which can be inserted and sheathed on the end of the driven shaft, an operating handle inserted and sheathed on the end of the driving shaft and the operating handle can drive the shaft to rotate, and a quick screwed rocking handle inserted and sheathed on the end of the transmission shaft and the rocking handle can drive the shaft to rotate. A power saving gear transmission mechanism is formed by the driving gear set and the driven gear set.
Description
The utility model relates to a kind of spanner.
Spanner is one of the most frequently used instrument in vehicle, machinery, maintenance of equipment and installation and even in the daily life, existing spanner has three kinds of structural shapes, a kind of is the changeless sheet spanner of bayonet socket, a kind of is the adjustable wrench that bayonet socket can be regulated change, and another is to have one group of socket wrench of screwing sleeve pipe.Not only waste time and energy when using existing spanner to screw the big bolt of diameter, nut, and be difficult to it is screwed or unloads, bolt, nut that special dismounting rust is lived are all the more so.One of plug-in mounting adds long handle to strengthen the application of force arm of force on pinch bar for bolt, the nut that will become rusty usually unloads, so because the point of application and spanner bayonet socket can't complete operations apart from increasing one people, thereby often need a people to hold up spanner one people's application of force to cause operational inconvenience.Simultaneously, be easy to cause personal injury, make the dangerous of operation change in case bayonet socket comes off.
The purpose of this utility model provide a kind ofly be suitable for the bigger bolt of diameter, nut driving is fastening or dismounting, operate fast, safe, laborsaving, a people gets final product the quick labour-saving spanner of complete operation.
Labour-saving spanner is by having case lid fast, the cabinet of lever, be bearing in one axle head on the cabinet and stretch out the outer driving shaft of cabinet, power transmission shaft, driven shaft, be positioned at being fixed on the driving gear on the driving shaft and being fixed on the driving tooth wheels that the driven gear with the driving gear engagement on the power transmission shaft constitutes of cabinet, be positioned at cabinet be fixed on the power transmission shaft driving gear and with its engagement and be fixed on the driven tooth wheels that the driven gear on the driven shaft constitutes, but sleeve stretches out the sleeve pipe of screwing of cabinet axially outer end at driven shaft, but sleeve stretches out at driving shaft and drives the operating grip that driving shaft rotates on the cabinet axially outer end, but sleeve can drive the rocking handle of screwing fast of power transmission shaft rotation on power transmission shaft constitutes the driving tooth wheels, the driven tooth wheels constitute laborsaving gear drive.
Utilize quick labour-saving spanner to screw bolt, nut is quick, laborsaving, a people gets final product complete operation, handling safety, convenience are suitable for screwing or dismantling the bigger bolt of diameter, nut and use.
Accompanying drawing is an embodiment of the present utility model, further specifies the utility model below in conjunction with embodiment.
Fig. 1 is the structure chart of quick labour-saving spanner.
Fig. 2 is the vertical view after quick labour-saving spanner shown in Figure 1 removes chassis lid.
As shown in the figure, labour-saving spanner is by the cabinet (6) that has lever (12) and case lid (4) fast, be bearing in one axle head on the cabinet and stretch out the outer driving shaft (3) of cabinet, power transmission shaft (9), driven shaft (10), be positioned at cabinet, be fixed on the driving gear (5) on the driving shaft, be fixed on the power transmission shaft, the driving tooth wheels that constitute with the driven gear (2) of driving gear engagement, be positioned at cabinet and be fixed on driving gear (8) on the power transmission shaft, be fixed on the driven tooth wheels of driven gear (11) formation that meshes with driving gear (8) on the driven shaft, but the sleeve of the complete configuration of different specification size is screwed sleeve pipe (7) what driven shaft stretched out the cabinet axially outer end, but sleeve drives the operating grip (13) that driving shaft rotates at the active axle head, but sleeve constitutes the driving tooth wheels at the rocking handle (1) of screwing fast that the transmission axle head drives the power transmission shaft rotation, the driven tooth wheels constitute laborsaving gear drive.Operating grip except that the schematic structure handle, also can use normally used have ratchet, a detent mechanism wave handle fast.
Utilize quick labour-saving spanner to screw or demounting bolt, during nut screw starting stage and dismounting screw the latter half since used moment very little, the available rocking handle of screwing fast drives the power transmission shaft quick rotation with bolt, nut precession or withdraw from, at bolt, nut screws stage and the demounting bolt nut stage of rising need be with very big moment the time, with the operating grip sleeve at the active axle head, because driving tooth wheels and driven tooth wheels constitute a laborsaving gear drive, thereby thereby apply common power and can make follower shaft produce very big rotating torque to be easy to nut screwed or unscrew unload.Operating personnel one holds spanner bandle one hand operated handle and gets final product complete operation when screwing bolt, nut, and not only convenient but also safe ignorant extremely collapses takes off the phenomenon generation.
Claims (1)
1, a kind of quick labour-saving spanner, it is characterized in that by the cabinet that has case lid and lever, be bearing in one axle head on the cabinet and stretch out the outer driving shaft of cabinet, power transmission shaft, driven shaft, being positioned at cabinet is fixed on the driving gear on the driving shaft and is fixed on the driving tooth wheels that the driven gear with the driving gear engagement on the power transmission shaft constitutes, be positioned at the driven tooth wheels that cabinet is fixed on the driving gear on the power transmission shaft and constitutes with the driven gear of its engages fixed on driven shaft, but sleeve stretches out the sleeve pipe of screwing on the cabinet axially outer end at driven shaft, but sleeve stretches out at driving shaft and drives the operating grip that driving shaft rotates on the cabinet axially outer end, but sleeve stretches out the rocking handle of screwing fast that drives the power transmission shaft rotation on the cabinet axially outer end at power transmission shaft constitutes the driving tooth wheels, the driven tooth wheels constitute laborsaving gear drive.
