In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a foldable portable screwdriver head, includes first sleeve, first telescopic inside is run through there is the screw rod, and first sleeve passes through threaded connection with the screw rod, the top of screw rod is fixed with the knob, the second sleeve has been cup jointed through the screw thread on the screw rod, and the second sleeve slides and cup joints in first telescopic inside, the telescopic bottom of second is fixed with the fixed block, the bottom of fixed block is fixed with the threaded rod, the bottom of threaded rod articulates there is the cutter arbor, be provided with the screw thread section on the cutter arbor, the stop collar has been cup jointed through the screw thread in the screw thread section, the bottom mounting of cutter arbor has the tool bit.

Preferably, the inner cross-sectional profile of the first sleeve is rectangular, and the outer cross-sectional profile of the second sleeve is rectangular.

Preferably, a limit ring is fixed at one end of the screw rod far away from the knob.

Preferably, the diameter of the knife rod is equal to that of the threaded rod, and the limiting sleeve is connected with the threaded rod through threads.

Preferably, the rubber sleeve is sleeved outside the first sleeve, and anti-skid lines are arranged outside the rubber sleeve.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses in the utility model discloses when using in great space, the stop collar cup joints on threaded rod and cutter arbor through the screw thread simultaneously, and threaded rod and cutter arbor can't take place relative rotation like this, can regard as normal screwdriver head to use, through rotating the knob, the knob drives the screw rod and rotates, and the screw rod can realize the extension and shorten of second sleeve through the screw drive between the second sleeve, can adjust holistic length like this according to the needs of application occasion, has improved the flexibility of using; when the space is narrow and cannot be vertically inserted, the limiting sleeve can be only sleeved on the cutter bar, so that the threaded rod and the cutter bar can relatively rotate, the cutter bar can be directly vertically inserted, the threaded rod and the parts above the threaded rod can be folded, screws in the narrow space can be screwed off, and the use flexibility is greatly improved;

2. the utility model discloses simple structure, the flexible operation, very big improvement convenience and the occasion of using.
