DETAILED DESCRIPTION

[0025] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-6 The present invention provides a technical solution: a precise fixed-length multifunctional wire stripper, comprising: two cross-matched first rod bodies 1, one end of the first rod body 1 is hinged with the second rod body 2 through a hinge, one end of the two first rod bodies 1 is respectively connected to a first mounting plate 3 and a second mounting plate 4, one end of the first mounting plate 3 is connected to a first blade 5, and a first placement frame 7 is connected above the second mounting plate 4, wherein one side of the first rod body 1 is connected to a second blade 6, and the other first rod body 1 is connected to a second placement frame 8 above, and one end of the second rod body 2 is connected to a rubber sleeve 9, the setting of the rubber sleeve 9 improves the stability when taking the wire stripper, and the hinged setting between the first rod body 1 and the second rod body 2 can facilitate subsequent personnel to shorten the length of the wire stripper, thereby facilitating the carrying of the wire stripper, the first placement frame 7 and the second placement frame 8 are both for placing cables, and then the first blade 5 and the second blade 6 are used to strip the rubber at the cable sheath.

[0027] A fixing block 10 is connected to one side of the first mounting plate 3, and a threaded groove is provided between the upper and lower parts of the fixing block 10. An adjusting bolt 11 is threadedly fitted in the vertical direction of the threaded groove. A first spring 12 is connected between the two first rod bodies 1. The first spring 12 is mainly used for automatically springing open after being compressed, which saves effort. The adjusting bolt 11 is mainly used for adjusting the cutting thickness during crosscutting and longitudinal cutting to reduce damage to the wire core.

[0028] A through hole 13 is formed on opposite sides of the first blade 5 and the second blade 6, and a fixing screw 14 is slidably fitted in the vertical direction of the through hole 13. One side of the first mounting plate 3 and the first rod body 1 are provided with mounting holes that are compatible with the fixing screw 14. The cooperation between the mounting hole and the fixing screw 14 can adjust the position of the first blade 5 and the second blade 6. By loosening the fixing screw 14, the first blade 5 and the second blade 6 can be slid along the through hole 13, and then the fixing screw 14 can be tightened to fix the position of the first blade 5 and the second blade 6.

[0029] In the first step of the practical stage, the travel adjustment bolt 11 is adjusted by comparing the diameter of the cable core, and then the first blade 5 is used to perform a circular cut on the stripping position. In the second step, the cable core is compared with the diameter, and then the cable is cross-cut with the second blade 6. The two steps can complete the stripping of the cable sheath. Although the core is the same, the travel of cross-cutting and circular cutting is different. The travel adjustment bolt needs to be adjusted to the appropriate position before the cutting operation can be performed.

[0030] A slide groove 15 is provided in the parallel direction of the first rod body 1, and a slider 16 is slidably matched with the slide groove 15 in the parallel direction. A notch 17 matched with the slider 16 is provided at one end of the second rod body 2, and a connecting block 18 is connected to one side of the slider 16. A through groove 19 for the connecting block 18 to slide is provided above the slide groove 15. A positioning groove 20 matched with the connecting block 18 is provided on one side of the second rod body 2. The slider 16 is a rectangular block structure, and the slide groove 15 is a rectangular groove structure. The arrangement of the rectangular block and the rectangular groove can further improve the stability of the second rod body 2 after being fixed.

[0031] A screw 21 rotates in a direction parallel to the slide groove 15, and a threaded hole compatible with the screw 21 is penetrated on the opposite side of the slider 16. A worm wheel 22 is connected to one end of the screw 21. A straight groove 23 is opened above one side of the slide groove 15. A worm 24 meshing with the worm wheel 22 rotates in a direction parallel to the straight groove 23. The screw 21 can be driven to rotate on one side of the first rod body 1 through the arrangement of the worm 24 and the worm wheel 22. Such an arrangement prevents the subsequent worm 24 from affecting the folding of the subsequent second rod body 2. The slider 16 can be driven to slide along the slide groove 15 through the arrangement of the screw 21, thereby completing the fixing of the position of the second rod body 2 and avoiding the second rod body 2 from folding at will.

[0032] A first annular groove 25 is provided on the circumferential side of the inner wall of the straight groove 23, and a ring body 26 that rotates in the first annular groove 25 is connected to the circumferential side of the worm 24. A connecting groove 27 is provided at one end of the worm 24, and a slide rod 28 is slidably fitted in the parallel direction of the connecting groove 27. A knob is connected to one end of the slide rod 28. The slide rod 28 is a rectangular groove, and the connecting groove 27 is a rectangular groove structure. The setting of the knob facilitates the rotation of the worm 24. The setting of the ring body 26 and the first annular groove 25 avoids the subsequent situation where the worm 24 is suspended, thereby improving the stability of the rotation of the worm 24.

[0033] A groove 29 is provided in the vertical direction of the slide rod 28, and a clamping rod 30 is elastically matched in the parallel direction of the groove 29. A clamping groove matched with the clamping rod 30 is provided on one side of the inner wall of the connecting groove 27. A second spring is connected between the groove 29 and the clamping rod 30. The setting of the clamping rod 30 can fix the position of the slide rod 28, and by extending the length of the slide rod 28, it is convenient for personnel to rotate the worm 24.

[0034] When the positions of the first rod body 1 and the second rod body 2 need to be adjusted, the card rod 30 is first pushed to make the card rod 30 slide out of the card slot, and then the slide bar 28 is pulled to make the slide bar 28 slide along the connecting groove 27. Then, the slide bar 28 will bounce back into the card slot after reaching the specified position. Then, the operator turns the knob to make the slide bar 28 connected to the knob rotate in the slide slot 15, and then the worm 24 connected to the slide bar 28 will rotate in the straight groove 23, and then the worm 24 will pass through the worm. The wheel 22 drives the screw rod 21 to rotate, and then the screw rod 21 drives the slider 16 to slide out of the slot 17, and then the second rod body 2 is folded, so that the second rod body 2 moves toward one side of the first rod body 1, and then the connecting block 18 slides into the slot 17 opened above the second rod body 2, and then the personnel turns the knob again to make the connecting block 18 slide into the slot 17 and establish a connection relationship with the slot 17, thereby completing the folding of the first rod body 1 and the second rod body 2, and the same is true when they need to be unfolded later.

[0035] A placement plate 31 is connected to one side of the first mounting plate 3, and a lighting lamp 32 is connected to the bottom of the placement plate 31. The lighting lamp 32 is connected to one side of the placement plate 31 by glue, and one end of the placement plate 31 is connected to a column with a T-shaped cross-section. A second annular groove that matches the column is opened on one side of the first mounting plate 3, and the column is magnetically engaged in the second annular groove. The column rotates in the second annular groove through the setting of the magnet, and the setting of the column avoids the placement plate 31 from being suspended, thereby improving the stability of the placement plate 31 when moving, and the position of the light can be adjusted by adjusting the position of the placement plate 31.
