Abstract

The utility model discloses a screwdriver, belonging to hardware tool type, mainly which is composed of a cutter body, a clamp shaft, a handle axle, a handle and a manipulating key five components, which is used as a standard screwdriver when tightening or loosening a generic screw. When the tightening force moment is very large or loosening a screw which is tightly tightened (which is composed of a turret heads and a socket cap screw), the screwdriver presents a reinforcing shape (the cutter body and the handle form an angle at 90 DEG), and the twisting force moment is increased as 5 to 8 times as that of the standard screwdriver, thus the conversion of both is very convenient and quick. The screwdriver has the advantages of simple structure, beautiful appearance and compaction.

Description

Power-increasing screwdriver

The utility model belongs to the hardware ﹠ tools class: bottle opener.

When tightening screw, screw-in process and rundown process are arranged.Existing standard bottle opener, screw-down torque is less, does not especially reach due screw-down torque when tightening the bigger screw of diameter, when needs unclamp fastening very firm screw, also is difficult for unclamping.In some occasion, the elbow bottle opener uses also inconvenient.

The purpose of this utility model: improve the performance of bottle opener, the convenience of the bottle opener that both maintained the standard.The effect that increases screw-down torque is arranged again, enlarge range of application.Provide a kind of simple in structure, easy to use, the novel bottle opener that screw-down torque is big.

The utility model mainly by: cutter hub, collet axis, arbor, handle, five parts of joystick key are formed.Below in conjunction with accompanying drawing utility model is described in detail.

Fig. 1 is its installation diagram (standard bottle opener shape)

Fig. 2 is its reinforcement shape outside drawing

As Fig. 1: cutter hub 1, (the bottle opener cutter hub of all size, the inner hexagon spanner of small-medium size etc.) upper end make standard quick change cutter hub tail, be installed in the standard quick change bottle opener chuck.The flat body of (being made up of nut 2, collet axis 3 lower ends) collet axis 3 upper end notches and arbor 5 lower ends is inlayed, with pin 4 riveteds.Collet axis 3 notch heads are circular arc (with pin 4 concentrics), flat body head one side of arbor 5 is circular arc, by collet axis 3 notches bottom, the head configuration of arbor 5 flat bodies is made gear, and collet axis 3 can only be done 180 °～90 ° towards a direction around pin 4 and turn back.(referring to Fig. 2).Collet axis 3, arbor 5 are installed in the handle 6, on the handle 6 lower end cylindricals pallet are arranged, and joystick key 7 is installed in handle 6 chutes, and are fastenedly connected with arbor 5 usefulness screws 8, can drive arbor 5 grades and slide up and down.Back-moving spring 9 is installed between handle 6, the arbor 5, and back-moving spring 9 thrust are covered 11 usefulness screws 10, are fastened on arbor 5 ends on lid 11, and bottle opener is standard shape.Making the standard bottle opener uses.

As Fig. 2: joystick key 7 is pushed into the next downwards, and collet axis 3 is pushed out handle 6 and turns back 90 ° around pin 4.During use on handle 6 lower end round trays pressurization switching shank, the screw-down torque of bottle opener increases 5～8 times than standard bottle opener.

When the openhanded joystick key 7 of opening, it is coaxial with arbor 5 that the thrust of back-moving spring 9 makes collet axis 3 turn back around pin 4, and return in handle 6 bodies upper end, and bottle opener automatically resets rapidly to standard bottle opener shape.

This increases the characteristics of power bottle opener:

1, make common bottle opener when general screw is tightened and use, be when the needs high-torque is tightened or unclamped screw and increase the power shape and use, the two conversion is very rapidly convenient.

2, simple in structure, compactness, good looking appearance, easy to manufacture, cheap, applicable situation is wide, can reduce labour intensity, increases work efficiency.

Claims

1, a kind of can turning back, the reinforcement bottle opener of the switching of can pressurizeing.The flat body that it is characterized in that arbor 5 is inlayed with the notch of the collet axis 3 that can turn back, with pin 4 riveteds, be installed in the handle 6 and can slide, flat body head one side of arbor 5 is circular arc, the notch head of collet axis 3 is circular arc, with pin 4 concentrics, and the head configuration of arbor 5 flat bodies, make gear with the bottom of collet axis 3 notches, collet axis 3 can only be done turning back of 180 °～90 ° in a direction around pin 4.On the handle 6 lower end cylindricals round tray is arranged, middle part one side has a chute, and joystick key 7 is installed in handle 6 chutes and arbor 5 usefulness screws 8 tighten together, and back-moving spring 9 is installed between handle 6, arbor 5, the lid 11.

2, reinforcement bottle opener according to claim 1 is characterized in that joystick key 7 surface reticulate patterns at quarter, and feel profile good and that handle 6 upper hopper chutes cooperate is the oval shape.

3, reinforcement bottle opener according to claim 1 is characterized in that back-moving spring 9 is installed in handle 6.Between the arbor 5, spring thrust acts on the lid 11 that arbor 5 is fastenedly connected.
