Embodiment
The utility model is described in further detail with reference to specific embodiment, described is to the utility model
Explanation rather than restriction.
Referring to Fig. 1~Fig. 7, a kind of screw thread turns round disk, including the screw thread disk 2 being located between shell 1 and end cap 4, screw thread disk 2
Front end is provided with helix, and the back side is provided with fan-shaped boss；The front end face radial direction of shell 1 is provided with radial notch, and claw is worn
The notch crossed on shell 1, the fixing tooth of claw end is nested between the helix of screw thread disk 2；The front end face of adjusting knob 3 passes through
The fan-shaped boss matched fits with the back side of screw thread disk 2, and the rear end face of adjusting knob 3 stretches out end cap 4.
The diameter of the fan-shaped boss at the described back side of screw thread disk 2 be more than its card external diameter, the fan-shaped boss of adjusting knob 3 with
The fan-shaped boss sequence of screw thread disk 2.
The end cap 4 and shell 1 are connected through a screw thread, and the axial direction of end cap 4 is designed with logical with the coaxial line of adjusting knob 3
Hole.
The extension of the adjusting knob 3 is provided with slip-resistant texture.
The claw is in the cross section on 1 housing axis direction, from case nose towards claw end increasingly
It is small, and clamping face is parallel with housing axis.
The helix coil direction of the screw thread disk 2 is counterclockwise (from having flank), helix spacing is 10
Millimeter.
Shell 1 is provided with three claws, and the claw is CR-V steel claws.
When adjusting knob 3 drives screw thread disk 2 to rotate, the threaded line fortune relative with the fixing tooth on claw on screw thread disk 2
Dynamic, under the limitation of the radial notch on shell 1, radial direction of the claw along the shell 1 is shunk or expanded, realization pair
The clamping of object；With the torsion of adjusting knob 3 after clamping, torque is applied to object.
The housing peripheral is provided with slip-resistant texture.
Specific embodiment is given below.
As shown in figure 1, the utility model, which provides a kind of screw thread, turns round disk, wherein, the screw thread, which turns round disk, includes shell 1, screw thread
Disk 2, adjusting knob 3, end cap 4 and claw (the first claw 5, the second claw 6, the 3rd claw 7), the profile of shell 1 is similar
Cylinder, the front end face of the shell 1 is radially provided with three radial notches to install the claw, the screw thread disk
It is provided with the tooth set on the notch of helix guiding, the notch and the claw 5,6,7 on 2 to coordinate, the adjusting knob 3
Front end face and the back side of screw thread disk 2 are provided with fan-shaped boss, and the mounting means of the end cap 4 and the shell 1 connects for screw thread
Connect.
The adjusting knob 3 is rotated, it, which is rotated, will drive the screw thread disk 2 coordinated with its end face to rotate, the spiral shell
The rotation of line disk 2 will cause the screw thread of the screw thread notch on the screw thread disk 2 and the tooth on the claw to coordinate generation relative
Fixing tooth on motion, the claw will produce slip in the screw thread notch on screw thread disk 2, its kinematic pair connects similar to screw thread
Fixing tooth on the screw thread pair form connect, the helical tooth and claw of threaded line formation constitutes the secondary structure of screw thread-like, by institute
The limitation of the radial notch on shell 1 is stated, the claw will can only shrink or expand along the radial direction of the shell 1,
The clamping to objects such as nuts is realized, hereafter, the slip-resistant texture part held on the shell 1 is reversed around its axis,
Torque is applied to objects such as nuts, the dismounting of threaded connection is realized.
Screw thread described in the utility model turns round disk, the advantage is that：By the way of three claws make radial motion simultaneously
The dismounting for various sizes of threaded connection is realized, because claw is towards the less and less structure in end so that this is practical
It is new the threaded connection of most of general positions both to be dismounted, some nuts being located in deep gouge can also be carried out
Dismounting.The utility model have it is simple in construction, it is easy to use, carry it is convenient, be easy to dismounting, the advantages of applied widely.
Example given above is to realize the utility model preferably example, and the utility model is not limited to above-mentioned implementation
Example.Those skilled in the art according to the technical characteristic of technical solutions of the utility model made it is any it is nonessential addition,
Replace, belong to protection domain of the present utility model.
