Please refer to Fig. 7 A, Fig. 7 B, Fig. 7 C, it is the perspective view and the left and right view of connector 16 in the utility model.Connector 16 1 ends link to each other with ratchet assembly 17 hollows by hexagonal, and screwdriver bit 13 vacancy from this passes; These connector 16 other ends are some polygonal convex tendons 161, link to each other with interior cover 15 front ends.
See also Fig. 8 A, it is the overall diagram of interior cover 15 in the utility model, and the rear end of interior cover 15 is provided with locating hole 153, is used for being connected and fixed guiding pole socket 7 by interior cover dog screw 14.Interior cover 15 is provided with a plurality of convex tendons 154, positions when being used to change screwdriver bit 13.8B with the aid of pictures again, Fig. 8 C, the A-A of cover 15 in it is respectively in the utility model, the sectional view of B-B, interior cover 15 front inner wall are provided with some grooves 151, when linking to each other with connector 16, polygonal convex tendon 161 inlay cards on this connector 16 form some spacing positions in storehouse 162 together in the groove 151 of interior cover front end, and only can allow the activity of a guide rod assembly in each spacing position in storehouse, the quantity of this spacing position in storehouse is identical with the quantity of this screwdriver bit, during as the replacing screwdriver bit, and the activity space of screwdriver bit.Six spacing positions in storehouse in the present embodiment, six screwdriver bits arranged, to should be arranged.The inside of interior cover 15 is provided with a block piece 152, and the centre position of cover 15 in block piece 152 is in is used for when changing screwdriver bit 13, stops the mobile of screwdriver bit 13, and screwdriver bit 13 is separated with axostylus axostyle 5.
See also Fig. 9 and Figure 10, it is respectively the overall diagram and the side view of overcoat.Be provided with some grooves 201 in the overcoat 2, be used for the convex tendon 154 on the cover 15 in the inlay card, thus the location when realizing changing screwdriver bit 13.If liken six screwdriver bits 13 to six gears,,, then must have six pairs of convex tendons 154 and groove 201 at least if six guide rod assemblies are promptly arranged just different convex tendon 154 inlay cards can be realized gear shift in different groove 201.
Specify the process of changing screwdriver bit 13 below in conjunction with five state diagrams:
State 1 sees also Figure 11:
Under this state, interior cover 15 and overcoat 2 are one in the axial direction, and can't relatively rotate.Employed screwdriver bit 13 stretches out from ratchet assembly 17, and by axostylus axostyle 5 from after withstand, thereby the quick change screwdriver bit automatic screwdriver of this band ratcher function can be twisted target.
State 2 sees also Figure 12:
When needs were changed screwdriver bit 13, overcoat 2 will move right, and drove lead 4 and axostylus axostyle 5 together moves right, and the cambered surface of protruding on the guide rod 11 112 is slided in the groove 501 of axostylus axostyle 5 simultaneously.Because the front end of axostylus axostyle 5 is equipped with guide rod magnet 6, thereby the screwdriver bit 13 that stretches out can be held together and move right.When block piece 152 is run in the rear end of screwdriver bit 13, because the inhibition of block piece 152 makes screwdriver bit 13 to continue to move to right again.And this moment guide rod 11 cambered surface 112 just in time slide into domatic 502 positions of axostylus axostyle 5, the strong magnet 12 of guide rod 11 front ends can just in time hold screwdriver bit 13.
State 3 sees also Figure 13:
When axostylus axostyle 5 continued to move to right, screwdriver bit 13 just can separate with axostylus axostyle 5 front ends.And since the sliding upper shaft levers 5 of the cambered surface 112 of guide rod 11 domatic 502 make axostylus axostyle 5 upwards lift, and screwdriver bit 13 together lifted by the strong magnet 12 of guide rod 11 front ends.Under this state, interior cover 15 can have relative rotation with overcoat 2, promptly can change needed screwdriver bit 13.When the selected screwdriver bit 13 that needs makes, just overcoat 2 can be moved to left.
State 4 sees also Figure 14:
In overcoat 2 moves to left process, along with the cambered surface 112 of guide rod 11 from axostylus axostyle 5 domatic 502 on slide gradually, and by means of the effect of guide rod 11 rear end return springs 10, guide rod 11 can be with screwdriver bit 13 downward turns.
State 5 sees also Figure 15:
When the cambered surface 112 of guide rod 11 just in time slips in the groove 501 of axostylus axostyle 5, the centre position of cover 15 in screwdriver bit 13 just in time drops to, and the front end of axostylus axostyle 5 also just in time withstands the rear end of screwdriver bit 13, and be with screwdriver bit 13 to stretch out ratchet assembly 17 always, just finished the replacing of screwdriver bit 13 up to the position of state 1.
From whole replacing process, the utility model only just can be finished the replacing of screwdriver bit by slip between the interior overcoat and rotation, simple to operate flexible, extremely easy to use.
More than disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop in the protection domain of the present utility model.
