As shown in fig. 1, fig. 2, fig. 3, and fig. 4, a quick-release screwdriver comprises a hollow handle 1, an extension rod 3 is movably inserted into the hollow handle 1, a screwdriver bit 4 is arranged at one end of the bottom of the extension rod 3, the screwdriver bit 4 is arranged outside the hollow handle 1, and a bidirectional threaded groove 8 is formed in the surface of the extension rod 3;

the adjusting device comprises a hollow handle 1, a pin 11 is transversely movably inserted into the adjusting shell 5, the pin 11 simultaneously penetrates through the side wall of the hollow handle 1 and the adjusting shell 5, a baffle 12 is arranged in the adjusting shell 5 on the pin 11, a first return spring 13 is sleeved outside the pin 11, the first return spring 13 is arranged in the adjusting shell 5, the first return spring 13 is arranged on one side, far away from an extension rod 3, of the baffle 12, and the first return spring 13 is used for pushing the pin 11 to the extension rod 3;

the bidirectional thread groove 8 is formed by intersecting two opposite thread grooves, the bidirectional thread groove 8 is the same as the thread groove formed on the surface of the reciprocating screw rod in the prior art, and the two thread grooves of the bidirectional thread groove 8 are not communicated at the end parts;

when the extension rod 3 extends out of the hollow handle 1 completely, the two pins 11 can be just matched with the two-way thread grooves of the two-way thread groove 8 respectively;

when the screwdriver is used, if a user needs to screw a screw in one direction, the pin 11 on one side of the hollow handle 1 is pulled out and fixed, the pin 11 cannot be matched with the bidirectional threaded groove 8, meanwhile, the pin 11 on the other side of the hollow handle 1 is pushed by the first return spring 13 to be embedded into the threaded groove in one direction of the bidirectional threaded groove 8, the screwdriver bit 4 is inserted into the tail of the screw by the user, the extension rod 3 is extruded into the hollow handle 1 by pressing the hollow handle 1, and in the process that the extension rod 3 enters the hollow handle 1, the pin 11 matched with the bidirectional threaded groove 8 limits the bidirectional threaded groove 8, so that the extension rod 3 rotates along one threaded groove of the bidirectional threaded groove 8, and the effect of pressing and screwing the hollow handle 1 is achieved;

when a user needs to screw the screw in the other direction, only the pin 11 embedded in the bidirectional threaded groove 8 needs to be replaced, so that the other pin 11 is embedded in the other threaded groove of the bidirectional threaded groove 8, and because the two threaded grooves of the bidirectional threaded groove 8 are in opposite rotating directions, the extension rod 3 can rotate along the other threaded groove of the bidirectional threaded groove 8 when the hollow handle 1 is pressed, and the effect of pressing the hollow handle 1 to screw the screw in the opposite direction is achieved;

when a user needs to use the conventional screwdriver, the two pins 11 can be matched with the two-way thread groove 8 at the same time, and at the moment, the two-way thread groove 8 cannot rotate along two directions at the same time, so that the extension rod 3 cannot be rotated, and the using effect of the conventional screwdriver can be realized; meanwhile, the user can change the length of the extension rod 3 extending out of the hollow handle 1 by changing the positions of the two pins 11 engaged on the bidirectional threaded groove 8.

The utility model discloses can be through changing two pins 11 and the conjunction relation of two-way thread groove 8, can realize can revolve the effect of twisting the screw through pressing cavity handle 1, to the dismantlement and the installation of longer screw, use this device to use more to use manpower sparingly, also more high-efficient.

As shown in fig. 2, further, a second return spring 7 is arranged inside the hollow handle 1, the second return spring 7 is arranged at one end of the top of the extension rod 3, and the second return spring 7 is used for pushing the extension rod 3 out of the hollow handle 1;

wherein, after the user pressed hollow handle 1 and twisted the screw, extension rod 3 was pressed into hollow handle 1 completely, through setting up second reset spring 7, can be with pressing into the extension rod 3 in hollow handle 1 completely by second reset spring 7 is automatic to be released, conveniently presses hollow handle 1 next time and twists the screw.

As shown in fig. 1 and fig. 2, further, a sealing cover 2 is threadedly mounted at the tail of the hollow handle 1, and the sealing cover 2 is used for sealing off the second return spring 7;

wherein, encapsulate second reset spring 7 through sealed lid 2, because sealed lid 2 can be dismantled, conveniently open sealed lid 2 and change and maintain second reset spring 7.

As shown in fig. 2, further, one end of the second return spring 7, which is far away from the sealing cover 2, is fixedly connected with a fixing block 9, and a rotating block 10 is rotatably mounted on one side of the fixing block 9, which is far away from the second return spring 7; the bearing is arranged in the fixed block 9, so that the rotating block 10 can be rotatably connected with the fixed block 9 through the bearing, and the friction force generated by rotation between the fixed block 9 and the rotating block 10 can be greatly reduced;

wherein, when screwing the screw owing to pressing cavity handle 1, extension rod 3 can take place rotatoryly, in order to avoid because the contact of second reset spring 7 and extension rod 3 influences extension rod 3's rotation, consequently set up rotatory piece 10 and utilize bearing greatly reduced extension rod 3 rotatory time, second reset spring 7 and the frictional force between the extension rod 3.

As shown in fig. 3 and 4, further, a pull ring 6 is arranged at one end of the pin 11 away from the extension rod 3, and a limit rod 14 is fixedly connected to a side surface of one end of the pin 11 close to the pull ring 6;

wherein, the hole side face that the regulation shell 5 is used for the peg 11 is provided with the bar aperture that can supply gag lever post 14 to pass through, and this bar aperture only is provided with one, when needing to aim at this bar aperture with gag lever post 14 rotation, this gag lever post 14 could pass through this bar aperture, under all the other angles, this gag lever post 14 all can not pass through this bar aperture.

Wherein, after pulling out pin 11 and breaking away from two-way thread groove 8, because pin 11 receives the promotion of first reset spring 13 has the trend of tending extension rod 3, consequently outside adjusting casing 5 through gag lever post 14 joint, can avoid pin 11 to remove to extension rod 3, and when not needing gag lever post 14 to carry out spacingly to pin 11, through aiming at this bar aperture with gag lever post 14, make gag lever post 14 can get into and adjust inside casing 5, then pin 11 no longer receives gag lever post 14 spacing, can be pushed to in the two-way thread groove 8 on extension rod 3 surface by first reset spring 13.

Those of ordinary skill in the art will understand that: the discussion of any embodiment above is meant to be exemplary only, and is not intended to suggest that the scope of the invention (including the claims) is limited to these examples; within the idea of the invention, also technical features in the above embodiments or in different embodiments can be combined, steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.

The present invention is intended to embrace all such alternatives, modifications and variances which fall within the broad scope of the appended claims. Therefore, any omission, modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
