The screwdriver bit set 2 includes a driver head rack 21, a mandril 22 and rotates main body 23.Wherein:
Shown in Figure 5, the front end of the driver head rack 21 is equipped with the mounting hole 211 being ejected for a selected screwdriver bit, institute
State it is uniformly distributed on 21 madial wall of driver head rack have 6 grades of locating slots 212, the intermediate channel of 6 grades of locating slots with where the push rod 4
Position consistency, i.e. push rod can pass through from intermediate channel.The end side of the driver head rack 21 is equipped with stern notch 213, the tail
Slot 213 is used to position the hand handle during the outer drawing hand handle.
The mandril 22 is a high magnetic steel stick, and the top of the mandril 22 is magnetic to connect screwdriver bit, the end magnetic of the mandril 22
Property the connection push rod 4.
The rotation main body 23 is as shown in Figure 6.The centre for rotating main body 23 is equipped with the first perforation for the push rod 4 and institute
Mandril 22 is stated to pass through.23 middle part of rotation main body is hollow, and side wall is equipped with inclined slideway 232.The rotation main body 23
Interior to be equipped with slideway shelf 24, the slideway shelf 24 is interior to connect a sliding block 25 by tension spring, and a block 26 is fixed on the rotation master
On body.The sliding block 25 is equipped with the second perforation, and second perforation is overlapped with the center of first time perforation, described to push away
Bar and mandril can move in the described second perforation.When hand handle pulls out, push rod 4 departs from second perforation, the cunning
Block 25 with the slideway shelf and rotates the slideway of main body and is moved to side under the action of the tension spring, when being moved to the side
The screwdriver bit and the block 26 are attracted by Bian Shi, the mandril, and the screwdriver bit is in replaceable position, as shown in Figure 3.
As shown in fig. 6, the lower end for rotating main body 23 is equipped with rotational positioning hole 231.It is set in the rotational positioning hole 231
There is the locating piece 233 that spring 232 connects, the combination of the rotational positioning hole and the locating piece can screwdriver bit set described in Automatic-searching
Interior locating slot then finds the screwdriver bit.
A baffle ring 6 is equipped between the screwdriver bit set 2 and the hand handle, to prevent the hand when pulling out the hand handle
Dislocation.
The application feature of the application is as follows:
From the point of view of Fig. 2, Fig. 2 is the initial state figure of the application state of the first embodiment of the present invention.Product initial shape
Under state:Screwdriver bit 1 and push rod 4 are tightly pulled together by mandril 22.Since selected screwdriver bit 1 protrudes screwdriver bit set, positioned at driver head rack
Mounting hole in, force in hand handle, by the effect of afterbody ratchet, driving screwdriver bit set 2 makes for use screwdriver.
Replace screwdriver:
With reference to shown in Fig. 3, hand handle is pulled open, push rod retreats therewith, due under the magnetic action of mandril 22, selected screwdriver bit
1 moves backward together with mandril 22;When push rod 4 departing from sliding block second perforation when, sliding block 25 under the action of tension spring,
It is moved with the slideway 232 on slideway shelf 24 and rotation main body 23 to side, until behind side, it, will due to the magnetic action of mandril 22
Screwdriver bit 1 is pulled together with mandril 22 and the block being fixed in the rotation main body.Meanwhile screwdriver bit is located at replaceable position
It puts.
When hand handle 3 is pulled to outermost end, as shown in figure 4, hand handle is fixed in stern notch.Screwdriver bit set 2 with it is described
A baffle ring 6 is equipped between hand handle 3, to prevent that the hand handle is dislocated when pulling out the hand handle.
Hand handle is rotated, replaces screwdriver bit.When hand handle 3 is pulled to outermost end, driver head rack 21 has had been extricated from 6 with rotating main body 23
The constraint of shelves locating slot, can arbitrarily rotate driver head rack 21 and hand handle 3.As shown in fig. 6, the lower end for rotating main body 23 is equipped with
Rotational positioning hole 231.Locating piece equipped with spring connection in the rotational positioning hole 231, the rotational positioning hole with it is described fixed
Position part with reference to can be described in Automatic-searching in screwdriver bit set locating slot, then find the screwdriver bit, replace corresponding screwdriver bit.
Hand handle is reduced, exits screwdriver bit.Hand handle 3 to screwdriver bit set is trusted and is pushed away.The operation in the same direction, while promote cunning therewith of push rod 4
Block makes it under the action of slideway to middle slip;When push rod 4 and mandril 22 overlap, push rod will push the mandril 22 and
Screwdriver bit 1 is gone ahead together, until screwdriver bit exposes the mounting hole on the driver head rack.On stern notch and the hand handle on driver head rack
It is closed, entire instrument is in state to be used.
Second embodiment:
Difference lies in the differences that screwdriver bit covers for the second embodiment and first embodiment.With reference to shown in Fig. 9 and Figure 10.It is described
Screwdriver bit set 7 includes a driver head rack 71 and an option 72.
The front end of the driver head rack 71 is equipped with the mounting hole 711 being ejected for a selected screwdriver bit, in the driver head rack 71
It is uniformly distributed to have multi gear locating slot 712.The intermediate channel of the multi gear locating slot 712 is consistent with 4 position of push rod, described
The end side of driver head rack 71 is equipped with a stern notch.
The option 72 is fixed on by a fixing bolt 73 in the screwdriver bit set.The option 72 includes 721 He of a torsional spring
One pendulum 722, one end of the pendulum 722 are fixed on the torsional spring 721.The other end of the pendulum 722 be arranged on it is described in
Between passage, the other end of the pendulum 722 can move to promote in the intermediate channel under the action of torsional spring 721 with it is described
The screwdriver bit of push rod connection, the push rod 4 is high magnetic steel stick, thus the push rod and screwdriver bit being attracted under magnetic action are can be put
What piece promoted.Pendulum 722 promotes, removes the screwdriver bit, completes to release the screwdriver bit connected on push rod.
3rd embodiment:
Difference lies in the differences that screwdriver bit covers for the 3rd embodiment and first embodiment.With reference to shown in Figure 11 to Figure 13.
The screwdriver bit set 8 includes a driver head rack 81 and screwdriver bit folder 82.The front end of the driver head rack 81 is equipped with for a choosing
Determine the mounting hole 811 that screwdriver bit is ejected.The end side of the driver head rack 81 is equipped with a stern notch, the side of the driver head rack 81
A selecting hole is offered on wall.The screwdriver bit folder 82 is arranged on by a shaft 821 in the selecting hole, and the screwdriver bit folder 82 is in institute
It states in selecting hole rotatably, is equipped with multi gear locating slot in the screwdriver bit folder, the screwdriver bit is correspondingly arranged in the locating slot, and is worked as
After the screwdriver bit folder is rotated in place, the screwdriver bit selected on the screwdriver bit folder is located at the position consistent with the push rod and mounting hole
On.
To sum up shown, the purpose of the application is that the function of integrated ratchet and quick-replaceable screwdriver bit is integrated, and simplifies spiral shell
The structure of silk batch, suitable for a variety of occasions.
Above-described embodiment is the demonstration of the application, is not limited the scope of the application.The claimed power of the application
Sharp scope is subject to disclosed in claims.
