Description

Technical Field

[0001] The utility model relates to the technical field of wire crimping pliers, in particular to a handheld electric high-efficiency wire crimping plier. Background Art

[0002] A wire crimping plier is a special wire crimping tool, mainly used for the connection of electric wires, cables and electrical components. It can clamp metal wire rods to ensure that the connection is tight and firm, effectively preventing current leakage and wire loosening. The wire crimping plier forms a complete circuit system by squeezing the electric wire and connecting it to a suitable terminal or plug. A handheld electric wire crimping plier, also known as a handheld electric wire crimping plier or an electric terminal plier, is a tool that uses electric energy such as a lithium battery to drive an electric motor to output kinetic energy for work. It is an indispensable important tool in the process of electrical installation, maintenance and production, and is widely used in the wire and cable connection work in the fields of electric power, communication, transportation, construction, etc.

[0003] After retrieval, a Chinese patent with the application number CN202022721103.0 discloses an electric wire crimping plier. During use, when the load of the motor is too high, the motor will be overloaded, which will damage the device. Therefore, an overload protection device needs to be added to further improve the structure and improve the safety performance. Therefore, through the design of the clutch disc group, when the load is too large, that is, when the torque of the motor is too large, the clutch disc groups will slip. In this way, when the transmission rod rotates, the rotation of the positioning sleeve cannot drive the transmission cover to rotate, and the power cannot be transmitted to the wire crimping device, and then the pressure for clamping the wire is stopped, realizing overload protection, which can prevent the motor from being damaged due to overload and improve the safety performance and service life.

[0004] During the use of the above-mentioned electric wire crimping plier, it is convenient to improve the safety performance and service life of the wire crimping plier. When the wire crimping plier presses the metal wire rod, since the metal wire rod is long and hard, when using the wire crimping plier, it is necessary to manually hold both ends of the wire rod to facilitate the wire crimping plier to press the part to be pressed, which increases the inconvenience during the use of the wire crimping plier. And if a person holds both ends of the metal wire rod to be squeezed for a long time, it is easy to cause hand fatigue, and it is easy to make the metal wire rod unstable when being squeezed, and then shift, affecting the crimping quality, thus reducing the work efficiency.

An installation block 2 is fixedly connected to the upper surface of the wire pressing pliers body 1. An installation sleeve 3 is arranged outside the installation block 2. A connecting plate 4 is fixedly connected to the outside of the installation sleeve 3. Installation shells 5 are fixedly connected to both sides of the connecting plate 4. A lead screw 6 is rotatably connected inside the installation shell 5. Moving blocks 7 are arranged at both ends of the lead screw 6. One of the moving blocks 7 is threadedly connected to the lead screw 6, and the other moving block 7 is rotatably connected to the lead screw 6. A clamping block 8 is fixedly connected to one side of the moving block 7. A soft rubber pad 9 is arranged on one side of the clamping block 8. A sprocket 10 is fixedly connected to the outside of the lead screw 6. Chains 11 are meshed and connected to the outside of the two sprockets 10. One end of one of the lead screws 6 is fixedly connected to a knob 12. The installation block 2 facilitates the installation of the installation sleeve 3, thereby facilitating the disassembly of the clamping structure. The rotation of the lead screw 6 facilitates driving one moving block 7 to move closer to the other moving block 7. The setting of the sprocket 10 and the chain 11 facilitates the rotation of one lead screw 6 to drive the rotation of the other lead screw 6, so that it is not necessary to turn the two knobs 12. The soft rubber pad 9 facilitates the protection and buffering of the contact surface of the wire to be clamped.

[0032] As shown in the attached Figure 1 figure, a handle 13 is rotatably connected to the lower surface of the wire pressing pliers body 1. A chute 14 and a plurality of hole grooves 19 are formed on one side of the wire pressing pliers body 1. Among them, the plurality of hole grooves 19 are all arranged below the chute 14. The chute 14 facilitates the sliding of the slider 15, and the hole grooves 19 facilitate the flexible engagement of the bolt 20.

[0033] As shown in the attached Figure 5 figure, two sliders 15 are slidably connected inside the chute 14. A rack 16 is fixedly connected to one side of one of the sliders 15. A connecting block 17 is fixedly connected to one side of the other slider 15. One end of the rack 16 is fixedly connected to one side of the connecting block 17, which improves the stability of the movement of the connecting block 17. One end of the rack 16 is fixedly connected to one side of the connecting block 17, which facilitates the connecting block 17 to drive the rack 16 to move.

[0034] As shown in the attached Figure 1As shown, a gear 18 is fixedly connected to one side of the handle 13. The gear 18 is meshed with the rack 16. A bolt 20 is threadedly connected to the bottom of the connecting block 17. An installation box 21 is fixedly connected to one side of the installation sleeve 3. The bolt 20 facilitates fixing the position of the moved connecting block 17.

[0035] As shown in the Figure 6 attachment, a pull rod 22 is embedded and installed on one side of the installation box 21. One end of the pull rod 22 is fixedly connected to a clamping block 23. A spring 24 is fixedly connected to one side of the clamping block 23. The spring 24 is sleeved on the outside of the pull rod 22. The pull rod 22 facilitates pulling the clamping block 23, and the spring 24 facilitates pushing the clamping block 23.

[0036] As shown in the Figure 4 attachment, a card slot 25 is opened inside the installation block 2. The clamping block 23 is engaged with the card slot 25, which facilitates the engagement of the clamping block 23, thereby limiting the installation sleeve 3.

[0037] Working principle: When using the wire pressing pliers, when fixing the object to be extruded, first pass the wire through the front extrusion end of the wire pressing pliers, and then turn the knob 12, so that the knob 12 drives the corresponding lead screw 6 to rotate. When one side of the lead screw 6 rotates, it drives the corresponding sprocket 10 to rotate. Under the driving action of the chain 11, it is convenient to drive the sprocket 10 on the other side to rotate, so as to drive the lead screw 6 on the other side to rotate. When the lead screws 6 on both sides rotate, it drives the rear moving block 7 and the clamping block 8 to move forward and close to the front moving block 7 and the clamping block 8, so as to facilitate clamping and fixing the wire, without manually holding the wire steady. When adjusting the angle of the handle 13 according to the required holding angle, first turn the bolt 20 to disengage from the corresponding hole 19, so as to release the limiting effect of the connecting block 17, and then slide the connecting block 17, so that the connecting block 17 drives the corresponding slider 15 to slide inside the chute 14, so as to facilitate pulling the rack 16 to move. Due to the meshing of the rack 16 and the gear 18, it is convenient to drive the gear 18 to rotate, so that the gear 18 drives the handle 13 to rotate, so as to facilitate adjusting the inclination angle. After adjustment, turn the bolt 20 in the reverse direction, so that under the action of the thread, it is screwed into the corresponding hole 19, so as to fix the moved connecting block 17 and fix the adjusted handle 13.
