Description
Technical field
The utility model belongs to the technical field of nuclear power station maintenance, is specifically related to a kind of screwdriver.
Background technology
In the installation and upkeep operation process of nuclear power station, wiring or take out stitches in electric panel cabinet of being everlasting, in wiring or when taking out stitches, needs to install or remove yi word pattern screw.At present, usually use the screwdriver shown in Fig. 1 install or remove yi word pattern screw, as shown in Figure 1, screwdriver 10 comprises handle 11, knife bar 12 and cutter head 13, and cutter head 13 is yi word pattern.During use, screwdriver 10 is aimed at screw 14 by operating personnel, then inserts in the groove at top 15 of yi word pattern screw 14 by cutter head 13, and it is vertical with the top 15 of screw 14 that cutter head 13 inserts screwdriver 10 after in the groove at top 15, last bit rotary screwdriver 10, to install or removable screw 14.Operating personnel are when bit rotary screwdriver 10, the size and Orientation of the power of bit rotary screwdriver 10 is all changing, easily make screwdriver 10 run-off the straight, screwdriver 10 is no longer vertical with the top 15 of screw 14, cutter head 13 also contacts no longer completely with the groove at top 15, causes cutter head 13 landing from the groove at top 15.Cutter head 13 after landing, needs again to be aimed at screw 14 by screwdriver 10, then is inserted by cutter head 13 in the groove at top 15 from the groove at top 15.In the installation or demolishing process of a screw 14, usual screwdriver 10 can landing be repeatedly from the groove at top 15, such one side can extend the activity duration of installing or removing yi word pattern screw, can damage the groove at the top 15 of screw 14 on the other hand, cause screw 14 not re-use.
Utility model content
In order to solve slotted point screwdriver easily from the problem of slippage in the yi word pattern groove of screw, the utility model proposes a kind of screwdriver, during to reach use slotted point screwdriver, screwdriver is not easily from the object of slippage in the yi word pattern groove of screw.
Screwdriver of the present utility model comprises handle, knife bar and cutter head, and on described knife bar, cover has magnetosheath, and this magnetosheath is tubular structure, the internal diameter of described magnetosheath and the equal diameters at the top of screw that is to be installed or that remove.
Wherein, described magnetosheath outer wall is provided with anti-slip veins.
Wherein, described knife bar is also arranged with Anti-slip cover, described Anti-slip cover is between magnetosheath and described handle.
Wherein, described Anti-slip cover is provided with projection.
Wherein, the diameter of described Anti-slip cover and the equal diameters of described magnetosheath.
Wherein, the cutter head of described screwdriver is yi word pattern.
Chasing tool of the present utility model has following beneficial effect:
1. when using screwdriver of the present utility model installation or removable screw, although the size and Orientation of the power of bit rotary screwdriver is all changing, but the magnetosheath of screwdriver of the present utility model is adsorbed on metallic plate, and the top of cutter head and screw is wrapped up, the connection of such cutter head and screw is more firm, cutter head can keep contacting completely with the groove at the top of screw, and screwdriver can keep vertical with the top of screw, thus make screwdriver not easily from slippage in the yi word pattern groove of screw, and after cutter head can be made to insert the yi word pattern groove of screw, once just can complete installation or the dismounting of screw.
2. the Anti-slip cover of screwdriver of the present utility model can fix magnetosheath further, prevents magnetosheath from sliding, and makes magnetosheath be wrapped in outside the top of cutter head and screw more firmly, prevents screwdriver from slippage in the yi word pattern groove of screw further.
3. screwdriver of the present utility model is simple to operate, easy to use, and material is easily purchased, and cost of manufacture is cheap.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that prior art uses screwdriver installation or removable screw;
Fig. 2 is the structural representation of screwdriver of the present utility model;
Fig. 3 is the using state figure of the screwdriver shown in Fig. 2;
Fig. 4 is the structural representation of the screwdriver of a kind of preferred structure of the utility model.
Detailed description of the invention
Screwdriver of the present utility model is introduced below in conjunction with accompanying drawing.
As shown in Figure 2, screwdriver 20 of the present utility model comprises handle 21, knife bar 22 and cutter head 23, and on knife bar 22, cover has magnetosheath 24, and magnetosheath 24 is tubular structure, the internal diameter of magnetosheath 24 and the equal diameters at the top of screw that is to be installed or that remove.Knife bar 22 is also arranged with Anti-slip cover 25, and Anti-slip cover 25 is between magnetosheath 24 and handle 21, and the diameter of Anti-slip cover 25 and the equal diameters of magnetosheath 24, operating personnel promote Anti-slip cover 25, and Anti-slip cover 25 can move on knife bar 22.
Screwdriver 20 of the present utility model is used to be installed in metallic plate or when removing from metallic plate by screw 14, as shown in Figure 3, the first step, by the yi word pattern groove of cutter head 23 alignment screw 14 of screwdriver 20, then inserts in the yi word pattern groove of screw 14 by cutter head 23; Second step, promotes magnetosheath 24 near the direction of screw 14, until magnetosheath 24 is adsorbed on metallic plate, and is wrapped up at the top 15 of cutter head 23 and screw 14; 3rd step, promotes Anti-slip cover 25 near the direction of magnetosheath 24, makes Anti-slip cover 25 prop up magnetosheath 24; 4th step, bit rotary screwdriver 20, to install or removable screw 14.
When using screwdriver of the present utility model installation or removable screw 14, although the size and Orientation of the power of bit rotary screwdriver 20 is all changing, but magnetosheath 24 is adsorbed on metallic plate, and the top 15 of cutter head 23 and screw 14 is wrapped up, such cutter head 23 is more firm with the connection of screw 14, cutter head 23 can keep contacting completely with the groove at the top 15 of screw 14, and screwdriver 20 can keep vertical with the top 15 of screw 14, thus make screwdriver 20 not easily from slippage in the yi word pattern groove of screw 14, and after cutter head 23 can be made to insert the yi word pattern groove of screw 14, once just can complete installation or the dismounting of screw 14.Wherein, promote Anti-slip cover 25, make Anti-slip cover 25 prop up magnetosheath 24, such Anti-slip cover 25 can fix magnetosheath 24 further, prevent magnetosheath 24 from sliding, make magnetosheath 24 be wrapped in the top 15 of cutter head 23 and screw 14 more firmly, prevent screwdriver 20 from slippage in the yi word pattern groove of screw 14 further.
As shown in Figure 4, magnetosheath 24 outer wall is provided with anti-slip veins 27, promotes magnetosheath 24 with handled easily personnel; Anti-slip cover 25 is provided with two projections 26, promotes Anti-slip cover 25 with handled easily personnel.
