Description

The a plurality of screwdrivers of folding hidden

Technical field

The utility model relates to hand-operated tools, specifically relates to a plurality of screwdrivers of a kind of folding hidden.

Background technology

Screwdriver on the market can be divided into two kinds of situations at present: the one, and fixing single cutter head is that cutter head separates with handle of a knife in addition, can be furnished with one group of cutter head.If use in different occasions, the former will carry many screwdriver, carries inconvenience.And the latter is easy to cause in use for some time, and the part cutter head is lost.

And the utility model itself fixedly is equipped with many group cutter heads, uses easy to carryly, effectively overcomes the defective of these two types of screwdrivers in the market.

Summary of the invention

In order to overcome in the market screwdriver or to carry inconvenience or cutter head such as loses easily at deficiency, the utility model provides a kind of folding hidden a plurality of screwdrivers.

The technical scheme that its technical problem that solves the utility model adopts is:

Have the five equilibrium deep-slotted chip breaker parallel around in the handle side with handle axis, collinear two ends in same five equilibrium deep-slotted chip breaker, have one parallel with handle axis, the screwdriver rod groove that one end is communicated with handle end, article two, all be not connected between the screwdriver rod groove, a screwdriver that the end is different is housed in each screwdriver rod groove, end near each the screwdriver knife bar in the middle of the handle all has oval groove, rotate with an end of bearing pin and screwdriver knife bar separately respectively or be slidingly connected, have in the bearing pin position one identical with each screwdriver knife bar diameter, and with the perpendicular straight trough of screwdriver rod groove.

The beneficial effect that the utlity model has is:

This screwdriver changes the mode of holding of traditional screwdriver, and blade is vertical 90 degree with cutter head; During use, only need cutter head with needs revolve and turn 90 degrees, push away toward interior one gently, promptly can fix.Equally, when finish using, also only need cutter head one is drawn gently outward, revolve and turn 90 degrees recovery and get final product, use very convenient; This screwdriver is furnished with 8 different screwdrivers, can satisfy the requirement of most of use occasion, is embedded in the blade side at ordinary times, can not hinder feel in use, and collection is convenient, and reduced volume also is very suitable for carrying.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model comprises:

Have the five equilibrium deep-slotted chip breaker 2 parallel around in handle 1 side with handle axis, collinear two ends in same five equilibrium deep-slotted chip breaker 2, have one parallel with handle axis, the screwdriver rod groove 8 that one end is communicated with handle end, article two, 8 of screwdriver rod grooves all are not connected, a screwdriver 4 that the end is different is housed in each screwdriver rod groove 8, end near each the screwdriver knife bar in the middle of the handle 1 all has oval groove 7, rotate or be slidingly connected with bearing pin 6 and an end of screwdriver knife bar separately respectively, have in bearing pin 6 positions one identical with each screwdriver knife bar diameter, and with the perpendicular straight trough 5 of screwdriver rod groove 8.

Near 4 mouthfuls of pits 3 that all have the degree of depth greater than deep-slotted chip breaker 4 of each five equilibrium deep-slotted chip breaker in 1 liang of outside of handle, be convenient to driver bit be transferred to finger.

The groove number of the described five equilibrium deep-slotted chip breaker 2 parallel with handle axis is 4～8, and present embodiment is four five equilibrium deep-slotted chip breakers 2, and totally eight on two screwdrivers 4 are respectively arranged in each deep-slotted chip breaker.

Shown in Fig. 4 (a) and (b), (c), during use, stir driver bit with hand at pit 3 places of deep-slotted chip breaker 4, the driver bit of needs revolved turn 90 degrees, gently toward with the perpendicular straight trough 5 of screwdriver rod groove 8 in one push away, the oval groove 7 of screwdriver knife bar promptly can be fixed along bearing pin 6 location in straight trough 5.Otherwise when finish using, also only need cutter head one is drawn gently outward, revolve and turn 90 degrees recovery and get final product, be embedded in the screwdriver rod groove of handle 1 side deep-slotted chip breaker and collect.Use very convenient.

The above-mentioned specific embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
