The purpose of the utility model is to provide a kind of attachment devices, of the existing technology to solve the problems, such as, facilitate two pieces
The connection of longer, different size object.
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
Please refer to Fig. 1-3, wherein Fig. 1 is the structural schematic diagram of the present embodiment attachment device；Fig. 2 is the present embodiment connection
The structural schematic diagram of fixed jaw in device；Fig. 3 is the top view of the present embodiment attachment device.
As shown in Figure 1, the present embodiment attachment device includes two clamping devices, each clamping device includes sliding sleeve 4
With fixed jaw 3, conical through-hole is provided in sliding sleeve 4, fixed jaw 3 is provided with open circles in the centre of truncated cone-shaped and fixed jaw 3
Cylinder, and the taper of fixed jaw 3 is equal with the taper of sliding sleeve conical through-hole, it is logical that fixed jaw 3 can be placed in sliding sleeve taper
Kong Zhong；As shown in Fig. 2, in the present embodiment, fixed jaw 3 includes three sub- corpus unguis 301 independent of each other, sub- corpus unguis 301 is cut
Face makes the inner wall indention of sub- corpus unguis 301, can increase fixed jaw 3 in fan annular, the inner wall indention of sub- corpus unguis 301
And grabbed grasp between object.
The present embodiment attachment device further includes the first pawl fixing sleeve 1 and the second pawl fixing sleeve 2, the first pawl fixing sleeve 1 and one
A sliding sleeve 4 is threadedly coupled, and the second pawl fixing sleeve 2 is threadedly coupled with another sliding sleeve 4, and the first pawl fixing sleeve 1 and second
Pawl fixing sleeve 2 is respectively positioned on the bigger one end that is open of sliding sleeve conical through-hole, and the first pawl fixing sleeve 1 and the second pawl fixing sleeve 2
Two fixed jaws 3 can be squeezed respectively, fixed jaw 3 is squeezed cooperation that can be closer with the inner wall of sliding sleeve 4 after power.Two
A clamping device is grabbed object for clamping one respectively, is grabbed object across conical through-hole, and pressed from both sides by each sub- corpus unguis 301
Tightly.
There are two connecting plate, the second pawl fixing sleeves 2 to have a connecting plate, the second pawl fixing sleeve 2 for first pawl fixing sleeve 1 tool
Connecting plate be threaded through between two connecting plates of the first pawl fixing sleeve 1, and two connecting plates of the first pawl fixing sleeve 1 pass through one
The rotation connection of the connecting plate of a rotation axis 5 and the second pawl fixing sleeve 2.5 one end of rotation axis band cap, and the other end is equipped with a pin
Nail causes the first pawl fixing sleeve 1 and the second pawl fixing sleeve 2 to be detached from for limiting, to prevent rotation axis 5 from falling off.
The present embodiment attachment device use process is as follows: grabbed one end of object 6 for first first and bored across sliding sleeve
Shape through-hole is placed between three sub- corpus unguis 301 of a fixed jaw 3, so that three sub- corpus unguis 301 is firmly grasped first and is grabbed object 6,
Then three sub- corpus unguis 301 are sent into sliding sleeve conical through-hole, make the side wall of sub- corpus unguis 301 and the side of sliding sleeve conical through-hole
First pawl fixing sleeve 1 sliding sleeve 4 corresponding with the fixed jaw 3, is then threadedly coupled, with the first pawl fixing sleeve 1 by wall contact
Screw, the first pawl fixing sleeve 1 can be given to 3 one clamping forces of the fixed jaw, match fixed jaw 3 and the inner wall of sliding sleeve 4 closely
It closes；Then one end that second is grabbed object 7 is passed through into three sub- corpus unguis that sliding sleeve conical through-hole is placed in another fixed jaw 3
Between 301, so that three sub- corpus unguis 301 is firmly grasped second and grabbed object 7, three sub- corpus unguis 301 are then sent into another sliding sleeve 4
Conical through-hole in, contact the side wall of sub- corpus unguis 301 with the side wall of sliding sleeve conical through-hole, then by the second pawl fixing sleeve 2
Sliding sleeve 4 corresponding with the fixed jaw 3 is threadedly coupled, and with screwing for the second pawl fixing sleeve 2, the second pawl fixing sleeve 2 can be given to
3 one clamping forces of the fixed jaw are fitted close the inner wall of fixed jaw 3 and sliding sleeve 4；Finally by the company of the first pawl fixing sleeve 1
The connecting plate of fishplate bar and the second pawl fixing sleeve 2 is rotatablely connected by rotation axis 5, as shown in figure 3, the first pawl fixing sleeve 1 and second
It is relatively rotatable to each other between pawl fixing sleeve 2, when connecting plate all long enoughs on the first pawl fixing sleeve 1 and the second pawl fixing sleeve 2,
Rotational angle between first pawl fixing sleeve 1 and the second pawl fixing sleeve 2 can be substantially equal to 360 °, and attachment device setting is existed
Sharply place can then pass through in corner etc., and the rotation between the first pawl fixing sleeve 1 and the second pawl fixing sleeve 2 bypasses the sharp place, from
And it avoids attached article there is a phenomenon where fracture due to the contact with sharply locating.
It is worth noting that, the side wall of fixed jaw 3 and the side wall of sliding sleeve conical through-hole are smooth, to guarantee fixed jaw 3
It is mobile towards the lesser one end of sliding sleeve conical through-hole opening as far as possible, so that so that fixed jaw 3 is given to first is grabbed object 6 or the second
Grabbed the sufficiently large clamping force of object 7.
In the description of the present invention, it should be noted that the orientation or positional relationship of the instructions such as term "inner", "outside"
To be based on the orientation or positional relationship shown in the drawings, it is merely for convenience of describing the present invention and simplifying the description, without referring to
