Wherein, which is between a reception position and an operating position, when the tool heads 3 are in reception position
When, as shown in Figure 1, the tool heads 3 are overturn towards the inside of the ring body 21, and when the tool heads 3 are in operating position, such as Fig. 2
It is shown, external overturning of the tool heads 3 towards the ring body 21.
The application method of the multi-purpose tool is described in detail below.In order to distinguish the tool heads of the upper and lower,
Figure 17 refers to the tool heads on upper layer into Figure 26 using tool heads 3A, and tool heads 3B refers to the tool heads of lower layer.
1, as shown in Figure 17 and Figure 18, at this point, tool heads 3A and tool heads 3B are in horizontal position, entire multi-functional work
Tool 1 is on reception position.At this point, the positioning horizontal stripe 33 of tool heads 3A is stuck in the locating groove 222 on 2 upper layer of fixed ring, work
The positioning horizontal stripe 33 of tool head 3B is stuck in the locating groove 222 of 2 lower layer of fixed ring.Tool heads 3A and tool heads 3B do not shake
It is dynamic.
2, as illustrated in figures 19 and 20, user turns clockwise tool heads 3A, and the positioning horizontal stripe 33 of tool heads 3A is from admittedly
Determine to deviate from the locating groove 222 on 2 upper layer of ring, the eccentric plectrum 34 of tool heads 3A is in locating notch 241, rotation opening 24 and partially
It is slipped in heart allocating slot 35, until the eccentric plectrum 34 of tool heads 3A touches the pin tongue 62 of the locking tongue pin 6 of tool heads 3B；
3, as shown in figure 21 and figure, continue to rotate clockwise tool heads 3A, the pin tongue 62 of the locking tongue pin 6 of tool heads 3B
Sliding surface 621 oppressed by the eccentric plectrum 34 of tool heads 3A, pin tongue 62 bounce back, the pressure bullet of the locking tongue pin 6 of tool heads 3B
Spring 63 is compressed simultaneously, and then eccentric plectrum 34 continues to slide over the sliding surface 621 of pin tongue 62, until tool heads 3A is turned to level
On position outwardly, at this point, tool heads 3A is on its operating position, pin tongue 62 turns again under the action of compression spring 63
Initial position.During the entire process of tool heads 3A overturning, tool heads 3B is in a horizontal position motionless always.Next, using
Person can directly rotate entire fixed ring 2 and screw or unscrew operation using tool heads 3A completion；
4, as shown in figure 23 and figure 24, after tool heads 3A use, user turns counterclockwise tool heads 3A, Zhi Daogong
The eccentric plectrum 34 of tool head 3A touches on the motion-stopping surface 622 of pin tongue 62 of the locking tongue pin 6 of tool heads 3B, at this point, tool heads
The pin tongue 62 of the locking tongue pin 6 of 3B can not bounce back.
5, as illustrated in figs. 25 and 26, user continues to turn counterclockwise tool heads 3A, and eccentric plectrum 34 continues to oppress work
Have the motion-stopping surface 622 of the pin tongue 62 of the locking tongue pin 6 of head 3B, so that rotating counterclockwise for low-angle occurs for entire tool heads 3B,
At this point, the positioning horizontal stripe 33 of tool heads 3B is deviate from from corresponding locating groove 222 or close to abjection, and tool heads 3A returns to water
On flat reception position.In this way, the finger of user can be routed up tool heads 3B using minimum strength, and by tool heads
3B overturns and is locked on its operating position, is particularly suitable for the one hand in narrow space and is operated.
It should be noted that a type of tool heads are only shown in Fig. 1 and Fig. 2, the type user of tool heads
It can arbitrarily replace, be easy to use.
The assembling steps of the multi-purpose tool of the invention with bipitch structure are illustrated below:
1), using tongue pin screw 65, locking tongue pin 6 is installed in tongue pin mounting groove 351；
2), a pair of of rotational pin 4 is encased in rotation circular hole 32 from the two sides of rotation circular hole 32 respectively；
3), the tail portion of tool heads 3 is put into fixed card slot 22, then, rotation adjusts screw 5, so that adjusting screw 5
The extruding inclined-plane 42 for squeezing rotational pin 4, until the other end of rotational pin 4 is pushed into respectively in corresponding rotational axis hole 221；
4), after the same method, other tool heads 3 are installed.
Using inclined-plane 42 is squeezed, the dismounting of tool heads 3 can be rapidly completed in user, convenient and efficient.By adjusting
Screw 5, the elasticity that the adjustable tool heads 3 of user cooperate with fixed card slot 22, the overturning dynamics of tool heads 3 is adjusted to
Optimum state.
In addition, adjusting screw 5 when user lays down with the magnetism repelled each other on the opposite end face of this pair of of rotational pin 4
When, rotational pin 4 can be leant out from rotation circular hole 32 automatically, convenient for users to replacing tool heads.
As shown in figure 27, multiple multi-purpose tools of the invention with bipitch structure can be overlapped by user, benefit
It is mutually attracted with the magnetism of fixed ring 2, more tools can be stored in this way.
Not limited to this, any change or replacement expected without creative work should all be covered in guarantor of the invention
Within the scope of shield.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
