Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in figures 1-3, the quick disassembling tool for the steel wire thread insert comprises a handle 1, wherein the middle position of the handle 1 is fixedly connected with one end of a column body 2, so that the tool is convenient to hold by a hand and is prevented from being scratched by a cutting edge when in use. The other end fixed connection toper blade 3 of cylinder 2, toper blade 3 have included three blade of putting to one side, and when the instrument wedged the steel wire swivel nut, locking recess has been surely gone out on the steel wire swivel nut to toper blade 3, and the rigidity that instrument and steel wire swivel nut are connected has been strengthened to three blade of putting to one side, prevents to skid to influence and dismantles. The material of the conical cutting edge 3 is alloy tool steel, and heat treatment quenching and tempering is carried out during processing, so that the plasticity and toughness of the conical cutting edge 3 are ensured. The tail end of toper blade 3 is at the bottom of the sword 5, and at the bottom of the sword 5 be planar structure, prevents to stab the staff, produces the unnecessary potential safety hazard.

As shown in fig. 4, which is a schematic view of the auxiliary groove retracting device 4, the bottom floor 404 is used as the primary carrier. Fixed connection has gone up shifting block 402 in the one side position of bottom plate 404, and the position of bottom plate 404 opposite side still the rigid coupling has push pedal 401, and the upper end of shifting block 402 and push pedal 401 all is located perpendicular groove 6, promotes push pedal 401 in perpendicular groove 6 for shifting block 402 displacement to the tight position of wire thread insert cover, shifting block 402 promotes the wire thread insert through the contact, makes the wire thread insert drop from the instrument. A return spring 403 is fixedly connected to one end of the bottom plate 404 close to the push plate 401, and is used for returning the pushed-out bottom plate 404 to the original position.

Furthermore, a vertical groove is arranged at the joint of the column body and the conical cutting edge, and is matched with an auxiliary groove withdrawing device.

Through adopting above-mentioned technical scheme, the plectrum removes in erecting the groove, and the steel wire swivel nut that will dismantle out moves back, has further increased the speed of dismantling to avoid the staff to contact the blade, increased the security of work.

Further, supplementary groove device that moves back includes the bottom plate, one side rigid coupling of bottom plate has the shifting block, the shifting block is located erects the groove, the opposite side rigid coupling of bottom plate has the push pedal, the push pedal upper end is located erects the groove, the one end that is close to the push pedal of bottom plate is connected with reset spring, reset spring still links to each other with the inside of cylinder.

Through adopting above-mentioned technical scheme, press the button and push away the bottom plate from the top down, drive the shifting block and remove in erecting the groove, after the shifting block removed the contact steel wire swivel nut, continue to remove and release the steel wire swivel nut, loosen the button and reset the bottom plate by reset spring for the speed of dismantling has increased the security.

Furthermore, the bases of the shifting block and the push plate are triangular.

Through adopting above-mentioned technical scheme, triangular base has increased the self stability of shifting block and push pedal, has also increased the durability of equipment, can not break because of the atress is big.

The specific use method comprises the following steps: the handle 1 and the cylinder 2 are held by hand, the tapered cutting edge 3 at the lower half part is inserted into the steel wire thread insert, and pressure is applied to the steel wire thread insert, so that the three cutting edges of the tapered cutting edge 3 are wedged into the steel wire thread insert. The three cutting edges of the tapered cutting edge 3 are uniformly stressed, a stop groove is cut on the steel wire thread insert, after rigid connection with the steel wire thread insert is formed, the handle 1 is rotated anticlockwise, and the steel wire thread insert is driven to rotate anticlockwise. If the rotated wire thread insert is not separated from the tool, the push plate 401 is pushed, and the push plate 401 pushes and displaces in the vertical groove 6 to drive the bottom plate 404 to displace. The bottom plate 404 drives the shifting block 402 to move, the shifting block 402 moves in the vertical groove 6 and moves to the position of the steel wire thread insert, the shifting block 402 pushes the steel wire thread insert through contact, the steel wire thread insert is removed, and the disassembly is completed.

The utility model has certain plasticity and toughness, good durability and long service life, and can easily and quickly disassemble the steel wire thread insert which is seriously worn; and the tool has compact structure, low processing cost and convenient and quick use, effectively improves the production and maintenance speed and reduces the labor intensity of workers.
