It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0024] Example 1

[0025] like Figure 1-10 As shown, the two handles 1 of the crimping pliers are hinged by a pliers head 2, and the pliers head 2 is used to crimp the terminal. A horizontally penetrating feeding hole 3 is provided on the pliers head 2. The terminal is placed in the feeding hole 3, and then the wire core is inserted into the terminal, and then the handle 1 is pressed to complete the crimping. The pliers head 2 is composed of two parts, a guide baffle 21 and a middle ring 22, wherein the middle ring 22 is fixed at one end of one of the handles 1, and there are two guide baffles 21, which are symmetrically fixed at one end of the other handle 1, and the middle ring 22 is located between the two guide baffles 21 and hinged therewith. The hole opened in the center of the guide baffle 21 is the feeding hole 3, and the feeding hole 3 penetrates along the axial direction of the guide baffle 21. Four guide rails 23 along the annular array of the feeding hole 3 are respectively provided on the opposite sides of the two guide baffles 21. For details, refer to Fig.10, a clamping block 25 is slidably provided on each guide rail; a sliding groove matching the guide rail is correspondingly provided on the clamping block 25, and four protrusions 24 are evenly provided along the inner wall of the inner ring 22, and the protrusions 24 are inserted between the clamping blocks 25, and each protrusion 24 is placed between two of the clamping blocks 25, wherein the ring 22 is coaxial with the guide baffle 21, and when crimping, the terminal enters along the penetration hole 3 and is placed in the center of the four clamping blocks 25, and the operating handle 1 rotates the protrusion 24, and squeezes the clamping block 25 to slide along the guide rail, so that crimping can be achieved, refer to Figure 2 , a return spring is arranged between the handle 1.

[0026] The original intention of developing this device is to solve the problem of electricians and power workers working at high altitudes, so that they can carry out wiring work efficiently, conveniently and quickly, and avoid the repeated steps of taking terminals from the tool kit, such as Figure 1 and Figure 3-5 As shown, by arranging a terminal box 4 with terminals on one side of the device, the terminals can be easily filled into the material penetration hole 3, and the terminal box 4 is detachable. The terminal box 4 is made of plastic, and a card table is arranged on its edge, which is engaged with the mounting groove 11 on the side of the handle 1, and can be inserted into the groove by lightly pressing. Similarly, it can also be designed as a threaded connection structure or an adsorption structure, as long as it can be easily disassembled. The specific structure of the terminal box 4 includes a box body 41 and a shift block 42. The box body 41 is used to carry the terminals, and the shift block 42 is used to hold the terminals. 42 is used to fill the terminals in the box body 41 into the penetration hole 3 for crimping. The box body 41 is provided with a storage bin for storing the terminals. A spring 43 is provided in the storage bin. Before use, the terminals need to be placed in the storage bin in sequence. The spring 43 always applies an elastic force to the terminals. A side cover plate 44 is provided on the open side of the storage bin. The side cover plate 44 is also mounted on the box body 41 in a snap-fit ​​manner. The box body 41 is snap-fitted into the mounting groove 11. The round hole on the other side of the box body 41 is just opposite to the penetration hole 3. Figure 4 As shown, at this time, if the shift block 42 is toggled, the frontmost terminal in the accommodating bin can be sent into the threading hole 3 along the round hole. More specifically, the shift block 42 also has a locking function. The box body 41 allows the shift block 42 to slide in a straight slide groove, and the end of the straight slide groove close to the round hole is recessed downward. When the shift block 42 fluctuates to the recessed position, it can be pressed down so that the shift block 42 is embedded in the recess, thereby completing the locking function. At this time, the shift block 42 blocks the next terminal from entering the standby area, and then the wire core can be threaded to prevent the terminal from being pushed out of the threading hole 3 in the opposite direction. Conversely, the shift block 42 is lifted up and then returned to the initial position. At this time, the next terminal enters the standby area under the action of elastic force.

[0027] like Figure 2 As shown, the device is provided with a portable clip 5 on one side of the handle 1, and the worker can clip it on the safety belt or waist belt during the operation.

[0028] In order to improve the terminal efficiency, the handle 1 is provided with an expansion compartment 12 for placing the terminal. Figure 6 As shown, in the present embodiment, the expansion bin 12 is provided with four chambers for placing terminals of different specifications. The open end of the expansion bin 12 is also provided with an upper cover 13 in a snap-fit ​​manner, which can be knocked open when in use. When power workers work at high altitudes, they need to climb along the electric poles to the meter box. It is very necessary to ensure that they carry all the tools every time. Carrying sufficient terminals can alleviate the troubles caused by terminal shortages.

[0029] Example 2

[0030] This embodiment is substantially the same as the embodiment 1, except that this embodiment further includes a cutting knife 6, which can be referred to Figure 1-2 Specifically, the cutting knife 6 is arranged on one of the handles 1, and the blade of the cutting knife 6 points to the other handle 1. When the two handles 1 are pinched together, the cutting work can be realized. Correspondingly, a cutting area 7 is arranged on the other handle 1. Specifically, as Figure 7 As shown, the cutting knife 6 includes a paddle 61, a handle 62 and a blade 63, the handle 62 is vertically arranged on one side of the blade 63, the paddle 61 is movably arranged on the side of the handle 62 away from the blade 63, and a circular protrusion 64 is arranged on one side of the paddle 61; a vertical slide groove adapted to the paddle 61 and the circular protrusion 64 is arranged on the handle 62; the vertical slide groove is also provided with a spring for resetting, and it is particularly important to note that a knife groove 66 adapted to the handle 62, the blade 63, the paddle 61 and the circular protrusion 64 is arranged on the handle 1, and the circular protrusion 64 is provided. Figure 8 and Fig. 9 A locking groove adapted to the circular protrusion 64 is provided on the upper side of the knife groove 66. When the paddle 61 is pressed, the blade 63 and the handle 62 can slide freely along the knife groove 66. When the paddle 61 is popped up, the circular protrusion 64 is stuck in the locking groove and locks the blade. When the blade 63 is not in use, it can be hidden in the knife groove 66 to avoid accidents.

[0031] Preferably, a plurality of annular notches 65 with different radii are provided on one side of the blade edge of the blade 63, and the annular notches 65 can be used for wire core stripping.

[0032] The device has a simple structure and is easy to carry. When crimping terminals, the device is not only highly efficient but also easy to use, thus avoiding safety hazards caused by cumbersome steps when electric power construction workers perform aerial work.
