Specific embodiment

The possible state sample implementation of the utility model is only illustrated with embodiment below, so not to limit the utility model institute The scope to be protected, conjunction are first chatted bright.

Fig. 1 to 5 is please referred to, shows a preferred embodiment of the utility model, the turning tool 1 of the utility model includes One ontology 10, a rotor 20, a mandrel 30 and a rotation limiting mechanism 40.

The rotor 20 is rotatably arranged in the ontology 10；The mandrel 30 and the rotor 20 are at rotation continuous action relation；This turn Dynamic limiting mechanism 40 includes one being set to the not opposite ontology 10 of the first limiting unit 41 of the mandrel 30, at least one and putting down in same radial direction The limited part 42 and an at least control piece 43 rotated on face, what which can fasten equipped with one with 41 phase of the first limiting unit Second limiting unit 421, and this at least a control piece 43 can drive the limited part 42 to make second limiting unit 421 in a releasing position And one move between latched position；Wherein, when second limiting unit 421 is located at the releasing position, second limiting unit 421 is not It is fastened with 41 phase of the first limiting unit and the mandrel 30 is free to rotate；When second limiting unit 421 is located at the latched position, Second limiting unit 421 is fastened with first limiting unit 41 to be connect and limiting the mandrel 30 can not be freely rotated.

First limiting unit 41 and 421 one of them of the second limiting unit include an at least protrusion 411, another one including extremely Few one can be with the recess portion 422 of the 411 phase clip of an at least protrusion.In the present embodiment, which surround for one and is somebody's turn to do The polygonal protrusion of mandrel 30, an at least recess portion 422 be one can with the polygonal recess portion of the polygonal protrusion phase clip, at this The polygonal protrusion can abut against with the polygonal recess portion and limit the mandrel 30 rotation when latched position.However, this at least one Protrusion and an at least recess portion can also be respectively provided with a tangent plane that can be abutted against；The mandrel can also be equipped with a plurality of recess portions, An at least protrusion recess portion can be abutted against with wherein one.

The ontology 10 includes a portions 11, which includes at least one sliding slot 111 radially provided, at least one control Part 43 is arranged in an at least sliding slot 111 and can slide along the mandrel 30 to drive the limited part 42 to move.Wherein, the limited part 42 along the axial linear movement of the mandrel 30 or oblique can move according to configuration.Specifically, which includes one Radial dimension be greater than this at least the sliding block 431 of a sliding slot 111 and one be arranged in an at least sliding slot 111 push rod 432, and the cunning Block 431 is connected to the push rod 432, which can drive the limited part 42, convenient for operating and for ease of maintenaince replacing.However, should Sliding block can also be arranged with the push rod integrally connected.

The portions 11 are equipped with an at least groove 112, which includes a side far from first limiting unit 41 Wall 113, the sliding block 431 of an at least control piece 43 are set to an at least groove 112 and can be resisted against this at the releasing position Side wall 113 can avoid or disperse the stress of the push rod 432 and limit the slip distance of an at least control piece 43, reduce zero Part damage, however, the side wall can also be closely arranged around the sliding block.It is recessed that the outer peripheral surface of the portions 11 can preferably be equipped with plural arc Face 114, convenient for holding and operating the control piece 43.

Preferably, an at least control piece 43 and the limited part 42 are detachably connected, easy to repair and replacement.In this reality It applies in example, which is set around the outside of the mandrel 30, and the peripheral wall of the limited part 42 is equipped with an at least screw hole 423, this is extremely A few control piece 43 can be with the thread segment 433 of 423 bolt of an at least screw hole including one.Specifically, which includes one Major diameter section 434 and a path section 435 equipped with the thread segment 433, the radial dimension of the major diameter section 434 are greater than an at least screw hole 423 and the distance that the push rod 432 is inserted into the limited part 42 can be limited, avoid the push rod 432 prominent inwardly and interfere the mandrel 30 Rotation, and it is easy to process.The rotation limiting mechanism 40 preferably includes two control pieces 43, which is connected to The radially opposite sides of an at least limited part 42, and can more steadily move the limited part 42.However, an at least control piece with should Limited part can also be integrated setting.

With reference to Figure 3 and Fig. 4, the inner wall radial inward of the portions 11 are equipped with single order portion 115；The rotation limiting mechanism 40 Another includes the elastic component 44 of a periphery for being sheathed on the limited part 42, and one end of the limited part 42 radially extends convex equipped with one Edge 424, the elastic component 44 is butted to have second limiting unit 421 towards the release The mobile trend in position.When the control piece 43 slides towards first limiting unit 41, which drives 42 edge of limited part It moves axially and the flange 424 is made to compress the elastic component 44, which interferences with first limiting unit 41 and limited Make the rotation of the mandrel 30.When the non-stress of control piece 43 sliding, which can automatically return to the release position It sets.
