Referring to fig. 1-7, the present invention provides a technical solution: a line pressing and wiring device for a power line comprises a binding clip 1, wherein a fixed arm 2 is fixedly connected to one side wall of the binding clip 1, a swing arm 3 is rotatably connected to the other side wall of the binding clip 1, the front end of the binding clip 1 is rotatably connected with a fixed base 4, a plurality of first line pressing teeth 401 with different sizes are arranged on the side wall of the fixed base 4, a sliding block 5 is slidably connected to the binding clip 1, a movable base 6 is rotatably connected to the sliding block 5, a plurality of second line pressing teeth 601 with different sizes are arranged on the side wall of the movable base 6, the plurality of first line pressing teeth 401 correspond to the plurality of second line pressing teeth 601 one by one, a driving rod 7 is rotatably connected to the rear end of the sliding block 5, a screw rod 8 is rotatably connected to the inside of the swing arm 3, the rear end of the screw rod 8 penetrates through the side wall of the swing arm 3 and is fixedly connected with a rotating handle 801, an adjusting block 9 is sleeved on the side wall of the screw rod 8, the rear end of the driving rod 7 is rotatably connected to the side wall of the adjusting block 9, the position of the adjusting block 9 on the swing arm 3 is adjusted by rotating the screw 8, so that the forward sliding amplitude of the adjusting slider 5 is adjusted, and the wire pressing force of the first wire pressing tooth 401 and the second wire pressing tooth 601 can be adjusted.

As shown in fig. 5 and 7, in order to enable the slider 5 to vertically slide back and forth on the binding clip 1 and to drive the slider 5 to slide forward and backward, the slider 5 can automatically slide backward and return, specifically, two guide shafts 10 are symmetrically and fixedly connected to the side wall of the binding clip 1, two sides of the slider 5 are respectively sleeved on the side walls of the two guide shafts 10, and a first spring 11 for returning and returning the slider 5 backward is sleeved on the guide shaft 10;

when the swing arm 3 is rotated, the slider 5 slides forwards along the guide shaft 10, at this time, the slider 5 compresses the first spring 11, so that the first spring 11 generates backward elastic force on the slider 5, during the forward sliding process of the slider 5, the second wire pressing tooth 601 and the first wire pressing tooth 401 clamp the copper nose and the wire, so as to implement wire pressing operation, and when the swing arm 3 is released, the first spring 11 generates backward elastic force on the slider 5, so as to implement resetting of the device to the state shown in fig. 2 (in this state, the second wire pressing tooth 601 is separated from the second wire pressing tooth 601).

As shown in fig. 2 and 4, in order to control the swing amplitude of the swing arm 3 and avoid the swing of the swing arm 3 being too large and inconvenient to grasp, specifically, a limiting groove 12 is formed on a side wall at the front end of the swing arm 3, a limiting bolt 13 is engaged and connected to a side wall of the binding clip 1, and a threaded end of the limiting bolt 13 is movably inserted into the limiting groove 12 to limit the swing amplitude of the swing arm 3;

as shown in fig. 4, when the swing arm 3 rotates, the limit bolt 13 slides inside the limit groove 12, and when the threaded end of the limit bolt 13 is located at the end of the limit groove 12, the end sidewall of the limit groove 12 blocks the limit bolt 13, so that the swing arm 3 cannot rotate outward, and at this time, the swing arm 3 has the maximum swing amplitude (as shown in fig. 2).

As shown in fig. 6, in order to avoid the fixed base 4 from freely rotating on the binding clip 1, specifically, a hidden groove 14 is formed on a side wall of the binding clip 1, a fixture block 16 is slidably connected inside the hidden groove 14 through a second spring 15, the second spring 15 exerts a certain elastic force on the fixture block 16, one end of the fixture block 16 away from the second spring 15 is in a spherical shape, a plurality of clamping grooves 17 are uniformly formed on a side wall of a rotating shaft of the fixed base 4, the number of the clamping grooves 17 is the same as that of the first crimping teeth 401, one end of the fixture block 16 is movably clamped inside the clamping groove 17, an opening of the hidden groove 14 is sealed through a nut 18, the nut 18 is connected to the opening of the hidden groove 14 through threaded engagement, so that the fixture block 16 and the second spring 15 are conveniently installed inside the hidden groove 14, and the fixture block 16 is clamped inside the clamping groove 17 through the elastic force of the second spring 15 (the spherical portion of the fixture block 16 is clamped inside the clamping groove 17), at this moment, the clamping effect of the fixture block 16 and the clamping groove 17 is achieved, so that the fixing base 4 can be fixed on the binding clip 1, the fixing base 4 is prevented from rotating freely, the fixture block 16 can be separated from the inside of the clamping groove 17 after the fixing base 4 is rotated forcefully, the fixing base 4 is convenient to rotate, the operation of pressing the wire by selecting any first wire pressing tooth 401 is facilitated, in addition, a hidden groove 14 is also formed in the sliding block 5, the second spring 15, the fixture block 16 and the nut 18 are arranged, a plurality of clamping grooves 17 are also uniformly formed in the side wall of the rotating shaft of the movable base 6, the movable base 6 is convenient to fix on the sliding block 5, the movable base 6 can also be rotated, and the operation of pressing the wire by selecting a second wire pressing tooth 601 corresponding to the first wire pressing tooth 401 is performed.

In order to increase the comfort level of an operator when gripping the fixed arm 2 and the swing arm 3, particularly, the fixed arm 2 and the rear end side wall of the swing arm 3 are both fixedly sleeved with a handle sleeve 19, and the handle sleeve 19 is preferably made of rubber.

The working principle is as follows: when the device is used, the device is opened to a state shown in fig. 2, in this state, a copper nose is placed on the first wire pressing tooth 401 right in front, then the swing arm 3 is grasped, at the moment, the drive rod 7 drives the slider 5 to slide forwards, so that the slider 5 drives the movable base 6 to slide forwards, the second wire pressing tooth 601 right in front slides forwards and then gradually approaches to the first wire pressing tooth 401 (shown in fig. 1), and thus the first wire pressing tooth 401 and the second wire pressing tooth 601 are mutually matched to clamp the copper nose, so that wire pressing and connecting operations are realized;

when the wire pressing and connecting operation is required to be performed on the power lines with different sizes, the first wire pressing tooth 401 and the second wire pressing tooth 601 with different sizes are selected, by rotating the limit bolt 13, so as to rotate the threaded end of the limit bolt 13 out of the interior of the limit groove 12, so that the rotation amplitude of the swing arm 3 can be increased (as shown in fig. 3), at this time, the first wire pressing tooth 401 is separated from the second wire pressing tooth 601, in this state, the fixed base 4 and the movable base 6 are rotated, so that the first wire pressing tooth 401 and the second wire pressing tooth 601 with different sizes are rotated to the front, after the first wire pressing tooth 401 and the second wire pressing tooth 601 are selected, the swing arm 3 is rotated to the state as shown in fig. 2 (in this state, the second wire pressing tooth 601 in the front cannot be separated from the fixed base 4, so that the fixed base 4 and the movable base 6 cannot rotate relatively, and the wire pressing stability of the device is increased), then, the limiting bolt 13 is rotated, so that the threaded end of the limiting bolt 13 is rotated into the limiting groove 12 again, and then the wire pressing and wiring operation is performed on the power lines with different sizes conveniently.
