Including handle and cutter body, the cutter body includes cutter arbor and the fixed tool bit of locating the cutter arbor both ends, and the cutter arbor is right angle L type cutter arbor, and the length of straight flange is 3cm -5cm, and the tool bit is flat mouthful tool bit and cross tool bit respectively, the handle end fixing is equipped with the connecting seat that is used for connecting the cutter body. Its demand to the screw superjacent air space is very little, can adapt to the screw elasticity operation in various corners and narrow space, can also switch between flat mouth and cross mouth at any time, uses convenient and fast.
Description
Technical field
The utility model relates to power maintenance tool technical field.
Background technology
Screwdriver in conventional maintenance tool mostly is straight shape screwdriver, and connect in electricity work at dress table, often can run into coping screw superjacent air space and be not enough to hold the screwdriver holded up, the situation causing this screw to be difficult to unscrew or tighten occurs.Often in order to the screw of on degree of tightness equipment then needs to dismantle other adjacent equipment, greatly reduce work on the spot efficiency.And an a handle screwdriver often corresponding cutter head, often need in maintenance process to carry multiple screwdriver, use also inconvenient.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of quarter butt L-type dual-purpose screwdriver is provided, it is very little to the demand of screw superjacent air space, the screw tightness operation of various corner and narrow space can be adapted to, can also be random switch between flat mouth and cross mouth, is easy to use quick.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of quarter butt L-type dual-purpose screwdriver, comprise handle and cutter hub, described cutter hub comprises knife bar and is fixed at the cutter head at knife bar two ends, and knife bar is right angle L-type knife bar, and the length of straight flange is 3cm-5cm, and cutter head is respectively flat mouth cutter head and cross cutter head; Described handle end is fixed with the Connection Block for connecting cutter hub.
As further technical scheme, described cutter head is welded in knife bar end.
As further technical scheme, the cross section of the straight flange of described knife bar is regular hexagon.
As further technical scheme, described Connection Block stretches into handle inner, and length is greater than a straight flange of knife bar, and Connection Block inside is provided with the hexagon spacing hole coordinated with knife bar, is interference fit with knife bar.
As further technical scheme, described handle outer is provided with insulating barrier.
The beneficial effect adopting technique scheme to produce is:
Very little to the demand of screw superjacent air space, the screw tightness operation of various corner and narrow space can be adapted to, can also be random switch between flat mouth and cross mouth, be easy to use quick.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
1-3 as shown in the figure, is an embodiment of a kind of quarter butt L-type of the utility model dual-purpose screwdriver, comprises:
Handle 1 and cutter hub 2.Cutter hub 2 comprises knife bar 21 and is fixed at the cutter head 22 at knife bar 21 two ends, and cutter head 22 is welded in knife bar 21 end, is connected firmly, not fragile during use.Knife bar 21 is right angle L-type knife bar, and the length of straight flange is 3cm-5cm, preferably 4cm, greatly reduces the demand to space directly over screw.Cutter head 22 is respectively flat mouth cutter head and cross cutter head, and the screw according to different model is selected, not only easy to carry, and it is also very convenient to change during use, improves operating efficiency.
The cross section of the straight flange of knife bar 21 is regular hexagon, and Connection Block 3 inside is provided with the hexagon spacing hole 4 coordinated with knife bar 21, is interference fit, is connected firmly with knife bar 21, and easy accessibility.Handle 1 end winding support is provided with the Connection Block 3 for connecting cutter hub 2, and the inside that knife bar 21 inserts Connection Block 3 is fixed.It is inner that Connection Block 3 stretches into handle 1, can firmly be combined with handle 1, difficult drop-off, ensures that serviceability is stablized.Connection Block 3 length is greater than a straight flange of knife bar 21, when knife bar 21 is inserted therein portion time, is not only connected firmly, and can also protect knife bar 21 and cutter head 22, prevents from colliding gouge.
Handle 1 outside is provided with insulating barrier 5.Can play a very good protection to operating personnel when operating.
After adopting said structure, make the demand of screwdriver to screw superjacent air space become very little, the screw tightness operation of various corner and narrow space can be adapted to; Screwdriver can also have more to use to be needed to switch between flat mouth and cross mouth easily, is easy to use quick, increases work efficiency.
