When an operator presses the two handles to close the two handles, the rotating rod 408 rotates relative to the first concave groove 407, the part of the rotating rod 408 located in the first concave groove 407 slides along the first concave groove 407, the first concave groove 407 pulls the sliding plug 403 to slide downwards through the connecting rod 404, the non-newtonian fluid in the lower cavity 405 enters the upper cavity 400, and the fourth spring 412 is stretched; when a worker loosens hands, due to the elastic force of the second spring 206, the two handles can be automatically and rapidly separated, the sliding plug 403 is not limited any more, the elastic force of the fourth spring 412 instantly pulls the sliding plug 403 to slide upwards, due to the characteristic performance of the non-Newtonian fluid, the non-Newtonian fluid in the upper cavity 400 is subjected to instant impact force, the non-Newtonian fluid becomes solid, the sliding plug 403 cannot move upwards and rapidly, the sliding plug 403 limits the rotating rod 408 through the connecting rod 404, the rotating rod 408 limits the two handles, and the situation that the two handles are reset rapidly and pop up to the hands of the worker is avoided; then, the plunger 403 slowly pushes up on the non-newtonian fluid, the plunger 403 slowly resets, the rotating rod 408 resets, and the two handles reset.
When the first clamp head and the second clamp head of the wire stripper are contacted with the conductor in the wire, the conductor in the wire can communicate the first conducting strip and the second conducting strip to form a passage; the rotating rod 408 rotates up and down to drive the coil 410 to cut a magnetic induction line between the first permanent magnet 406 and the second permanent magnet 409 to generate current, and when a conductor in the electric wire connects the first conducting strip and the second conducting strip, the electromagnet 401, the first conducting strip and the second conducting strip form a passage, the generator supplies power to the electromagnet 401, the electromagnet 401 is electrified, the electromagnet 401 can adsorb the sliding plug 403, the sliding of the sliding plug 403 is avoided, an operator cannot continuously press the two handles, and therefore the conductor of the electric wire is prevented from being damaged; after the wire is removed, the electromagnet 401, the first conductive sheet and the second conductive sheet form an open circuit, the electromagnet 401 is powered off, and the sliding plug 403 can slide. So that the conductor in the electric wire can be prevented from being damaged.
The specific implementation process is as follows:
when the second spring 206 needs to be replaced, the sliding block 207 is pressed inwards, the sliding block 207 pushes the fixing block 205 inwards to move, the fixing block 205 inwards moves to enable the telescopic rod 203 and the first spring 204 to contract, the mounting block 201 loses spacing at the moment, the two mounting blocks 201 and the second spring 206 can be detached, after a new geothermal spring is mounted on the two mounting blocks 201, the mounting block 201 is inserted into the mounting cavity 101 in an aligning mode, the fixing block 205 can move inwards to enable the telescopic rod 203 and the first spring 204 to contract, the mounting block 201 is continuously pushed, until the telescopic rod 203 and the first spring 204 recover to the original length, the fixing block 205 is pushed into the connecting groove 102, and replacement of the second spring 206 can be completed.
When the wire stripper needs to be folded and stored, the right end of the connecting rod 307 rotates relative to the handle 100, so that the connecting rod 307 can be folded, then the fixing rod 304 is pulled to enable the fixing hole 308 to be aligned with the fixing column, then the fixing rod 304 is loosened, the fixing ring 306 and the fixing rod 304 are pushed into the fixing hole 308 in the connecting rod 307 through the third spring 305, and then the limiting on the connecting rod 307 can be completed, so that the wire stripper can be folded and stored.
In the wire stripping process, when the two handles are pressed by the hands of an operator to close the two handles, the left end of the rotating rod 408 slides downwards, the rotating rod 408 pulls the sliding plug 403 to slide downwards through the connecting rod 404, the non-Newtonian fluid in the lower cavity 405 enters the upper cavity 400, and the fourth spring 412 is stretched; when a worker releases hands, the fourth spring 412 resets to instantly pull the sliding plug 403 to slide upwards, the non-Newtonian fluid in the upper cavity 400 instantly becomes solid to prevent the sliding plug 403 from rapidly moving upwards, the two handles cannot be rapidly reset, then the sliding plug 403 slowly extrudes the non-Newtonian fluid upwards, the sliding plug 403 slowly resets, the rotating rod 408 resets, and the two handles slowly reset.
In the wire stripping process, when a first clamp head and a second clamp head of the wire stripper are in contact with a conductor in a wire, the conductor in the wire can communicate a first conducting strip with a second conducting strip to form a passage; the rotating rod 408 rotates up and down to drive the coil 410 to cut the magnetic induction line between the first permanent magnet 406 and the second permanent magnet 409 to generate current, and compared with a generator, the generator supplies power to the electromagnet 401, the electromagnet 401 is electrified, the electromagnet 401 can absorb the sliding plug 403, so that the sliding plug 403 is prevented from sliding, an operator cannot continuously press the two handles, and therefore the conductor of the electric wire is prevented from being damaged; after the wire is removed, the electromagnet 401, the first conductive sheet and the second conductive sheet form an open circuit, the electromagnet 401 is powered off, and the sliding plug 403 can slide.
The above description is only an embodiment of the invention, and the common general knowledge of the known specific structures and characteristics in the schemes is not described herein too much. It should be noted that, for those skilled in the art, without departing from the structure of the invention, several changes and modifications can be made, which should also be regarded as the protection scope of the invention, and these will not affect the effect of the invention and the practicability of the patent.
