[0025] The multi-purpose pliers will now be described in detail. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.
[0026] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0027] Please see Figure 1-8 This embodiment provides a multi-purpose pliers, comprising: an insulated handle a1, an insulated handle b2 on one side of the insulated handle a1, a connecting rod a5 fixedly connected to one side of the insulated handle a1, a connecting rod b6 fixedly connected to one side of the insulated handle b2, and alarm blocks 7 fixedly connected to one side of both the connecting rod b6 and the connecting rod a5; a clamping assembly disposed on one side of the insulated handle a1 for clamping cables or wires, the clamping assembly comprising: a clamping block 4, a clamping plate 401, and adjusting bolts 402; a rotating screw 403 fixedly connected to one side of the connecting rod b6, a fixing screw 404 at one end of the rotating screw 403, a clamping block 4 fixedly connected to one end of the fixing screw 404, adjusting bolts 402 on both the upper and lower surfaces of the clamping block 4, a clamping plate 401 fixedly connected to one end of each adjusting bolt 402, and a detachable connecting tube 405 on the outside of the fixing screw 404.
[0028] When in use, pull the insulating handle a1 to rotate it on the rotating screw 403, causing the two clamp heads 8 to separate from each other. Then, place the cable or wire between the two clamp heads 8, and simultaneously position the cable or wire between the two clamping plates 401. Tighten the adjusting bolt 402 to bring the two clamping plates 401 closer together to clamp the cable or wire. Then, apply pressure to the insulating handle a1 to bring the two plates closer together and cut the cable or wire.
[0029] The rotating screw 403 has an external thread at one end and an internal thread inside the connecting pipe 405. The rotating screw 403 is connected to the fixing screw 404 through the connecting pipe 405. Both clamping plates 401 are located inside the clamping block 4 and are symmetrically arranged. When the clamping block 4 is not needed, the connecting pipe 405 can be turned to unscrew the fixing screw 404, thereby disconnecting the clamping block 4 from the rotating screw 403 and disassembling the clamping block 4.
[0030] The insulating handle a1 has a replacement component on one side, which includes: a fastening bolt 802, a fastening nut 803, a metal U-shaped block 702, and a connecting block 801. The metal U-shaped blocks 702 are fixedly connected to one side of the two alarm blocks 7. The top of the two metal U-shaped blocks 702 is provided with a fastening bolt 802. The two alarm blocks 7 are provided with pliers 8 on one side. The rubber bands 302 on the outside of the insulating handle a1 and the insulating handle b2 are all fitted. The bottom end of the fastening bolt 802 passes through the metal U-shaped block 702 and the connecting block 801 and is connected to the fastening nut 803. The fastening nut 803 is threadedly connected to the fastening bolt 802.
[0031] When the pliers head 8 needs to be replaced as required, the fastening bolt 802 and fastening nut 803 on the metal U-block 702 can be turned off to disconnect the connecting block 801 from the metal U-block 702. Then, the pliers head 8 to be replaced can be taken out, the connecting block 801 on one side of the pliers head 8 can be pushed into the opening of the metal U-block 702, and one end of the fastening bolt 802 can be passed through the through hole of the connecting block 801 and the metal U-block 702. Then, the fastening nut 803 can be tightened on one end of the fastening bolt 802 to complete the replacement of the pliers head 8, so that the pliers can perform various types of clamping, cutting or bending tasks.
[0032] Both alarm blocks 7 have buzzers 701 fixedly installed inside them, and two clamp heads 8 are fixedly connected to one side of each other with connecting blocks 801. When it is necessary to test the insulation of cables or wires, the clamp heads 8 can be brought into contact with the cables or wires. When the cables or wires leak current, the current is transmitted to the clamp heads 8, connecting blocks 801, fastening bolts 802 and fastening nuts 803, and then to the buzzers 701, which will make the buzzers 701 sound an alarm to remind the cable or wires of leakage.
[0033] The insulating handle a1 has a storage groove 101 at the bottom and the insulating handle b2 at the top. The insulating handle a1 has a threaded hole a102 at the top and the insulating handle b2 at the bottom. The insulating handle a1 has a bolt 103 at the top and the insulating handle b2 at the bottom. The two storage grooves 101 are connected to the adjusting rods a3 through the rotating shaft. The two adjusting rods a3 have a threaded hole b301 on one side.
[0034] When operation in confined spaces is required, unscrew the bolts 103 on the insulating handles a1 and b2 from the threaded holes a102, then pull out the rubber bands 302 on the insulating handles a1 and b2 to release the rubber bands 302 from fixing the adjusting rod a3. Next, pull the adjusting rod a3 inside the two storage slots 101 to rotate the adjusting rod a3 around the pivot, so that the threaded holes a102 and b301 are aligned. Then screw one end of the bolt 103 into the threaded holes a102 and b301 to fix the adjusting rod a3 through the threaded holes a102.
[0035] The working principle is as follows:
[0036] When the pliers head 8 needs to be replaced as required, the fastening bolt 802 and fastening nut 803 on the metal U-block 702 can be turned off to disconnect the connecting block 801 from the metal U-block 702. Then, the pliers head 8 to be replaced can be taken out, the connecting block 801 on one side of the pliers head 8 can be pushed into the opening of the metal U-block 702, and one end of the fastening bolt 802 can be passed through the through hole of the connecting block 801 and the metal U-block 702. Then, the fastening nut 803 can be tightened on one end of the fastening bolt 802 to complete the replacement of the pliers head 8, so that the pliers can perform various types of clamping, cutting or bending tasks.
[0037] If the clamping block 4 is not needed, the connecting pipe 405 can be turned to unscrew the fixing screw 404, thereby disconnecting the clamping block 4 from the rotating shaft screw 403 and disassembling the clamping block 4.
[0038] When operation in confined spaces is required, unscrew the bolts 103 on the insulating handles a1 and b2 from the threaded holes a102. Then, pull out the rubber bands 302 on the insulating handles a1 and b2 to release the rubber bands 302 from fixing the adjusting rod a3. Next, pull the adjusting rod a3 inside the two storage slots 101 to rotate the adjusting rod a3 around the pivot, so that the threaded holes a102 and b301 are aligned. Screw one end of the bolts 103 into the threaded holes a102 and b301 to fix the adjusting rod a3 through the threaded holes a102, thereby changing the length of the insulating handles a1 and b2.
[0039] Furthermore, pull the insulating handle a1 to rotate it on the rotating screw 403, causing the two clamp heads 8 to separate from each other. Then, place the cable or wire between the two clamp heads 8, simultaneously positioning the cable or wire between the two clamping plates 401. Tighten the adjusting bolt 402 to bring the two clamping plates 401 closer together, clamping the cable or wire. Next, apply pressure to the insulating handle a1 to bring the two plates closer together and cut the cable or wire.
[0040] In addition, when insulation testing of cables or wires is required, the clamp head 8 can be brought into contact with the cable or wire. When the cable or wire leaks current, the current is transmitted to the clamp head 8, the connecting block 801, the fastening bolt 802 and the fastening nut 803, and then to the buzzer 701, which will sound an alarm to alert that the cable or wire is leaking current.
