DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0021] like Figure 1 - Figure 5As shown, the virtual axis pivot includes a first fixed seat 1 and a first sliding member 11, a second fixed seat 2 is placed on the side of the first fixed seat 1, and the first sliding member 11 is arranged below the first fixed seat 1, and a second sliding member 12 is placed below the second fixed seat 2, and a second docking member 10 is placed in the groove of the first sliding member 11, and a first docking member 9 is placed in the groove of the second sliding member 12, and the first docking member 9 and the second docking member 10 are staggered with each other, and the first fixed seat 1 and the second fixed seat 2 can be adjusted in angle according to the connected first sliding member 11 and the second sliding member 12, and the connected sliding shaft and the torque shaft. When the relative position between the first fixed seat 1 and the second fixed seat 2 needs to be changed, one of the first fixed seat 1 and the second fixed seat 2 is used as a supporting point, and the other fixed seat is swung at this time, so that when the angle of the fixed seat is deflected, the sliding member under the fixed seat will slide with it, thereby reducing the empty stroke feel of the fixed seat during movement, thereby improving the lubrication feel during movement.

[0022] The first sliding member and the first docking member are connected by a first sliding axis, and the second sliding member and the second docking member are connected by a second sliding axis, and the side of the first docking member away from the first sliding member and the second fixed seat are connected by a second torsion axis, and the side of the second docking member away from the second sliding member and the first fixed seat are connected by the first torsion axis. The design of the first docking member 9 and the second docking member 10 allows them to be staggered with each other, so that when one of the fixed seats is rotated, the range of force exerted on the two and the size of the force points are consistent, thereby ensuring the stability between the first fixed seat 1 and the second fixed seat 2. At the same time, the first docking member 9 and the second docking member 10 are also connected to the first fixed seat 1 and the second fixed seat 2 through the first torsion axis 5 and the second torsion axis 7 respectively, which can not only increase the firmness of the connection, but also relieve the stress caused by the workload.

[0023] The left side of the first torsion shaft 5, the second torsion shaft 7, the first sliding shaft 14 and the second sliding shaft 15 are all provided with a blocking block 8, and the first torsion shaft 5, the second torsion shaft 7, the first sliding shaft 14 and the second sliding shaft 15 are all engaged with a C-type fastener 6 on the side away from the blocking block 8. The blocking blocks 8 provided by the first torsion shaft 5, the second torsion shaft 7, the first sliding shaft 14 and the second sliding shaft 15 effectively prevent the excessive movement of the shaft, so as to limit the shaft from shifting when it is constantly rotating, thereby enhancing the stability and reliability of the device. The C-type fastener 6 further ensures that the shaft is fixed at the required position, wherein the C-type fastener 6 can adjust the fixed position of the shaft according to actual needs to enhance the overall stability of the device.

[0024] First connecting ears 3 are provided on both sides of the first fixing base 1, and first connecting holes 301 are provided above the two groups of first connecting ears 3, which are convenient for connection with external equipment or structures, and second connecting ears 4 are provided on both sides of the second fixing base 2, and second connecting holes 401 are provided above the two groups of second connecting ears 4, so that the first fixing base 1 and the second fixing base 2 can be more conveniently connected to other components.

[0025] A first slide groove 16 is provided above the first fixed seat 1 and the second fixed seat 2, and a sliding head 13 is inserted above the two sets of slides, and a blocking piece 17 is engaged at the bottom of the sliding head 13. The sliding head 13 is inserted in the slide groove, and the bottom of the sliding head 13 is engaged with the blocking piece 17. This design allows the sliding head 13 to slide freely in the slide groove, and the blocking piece 17 plays a limiting role to prevent the sliding head 13 from sliding out of the slide groove.

[0026] Second slide grooves 18 are provided on both sides of the first fixed seat 1 and the second fixed seat 2, and the two groups of second slide grooves 18 are the same size, and the second slide grooves 18 cooperate with the first slide grooves 16. Therefore, when the fixed seat is deflected, the sliding head 13 slides in the first slide groove 16, and the sliding member connected to the fixed seat will be offset. At this time, the sliding shaft used for the sliding member and the docking member will slide through the second sliding groove. Therefore, the first slide groove 16 and the second slide groove 18 can cooperate with each other, so that when the sliding member slides, the axis body whose movement is restricted follows to slide.

[0027] In summary, the utility model is through the first fixed seat 1 and the first sliding member 11, wherein the first fixed seat 1 is connected to the first sliding member 11 below, and the second fixed seat 2 is connected to the second sliding member 12 below. At this time, the sliding head 13 is inserted into the first sliding groove 16 above the first fixed seat 1 and the second fixed seat 2, so that the sliding head 13 passes through the fixed seat and the sliding member. At this time, the end of the sliding head 13 is connected with a baffle 17, so that the sliding head 13 is engaged, so that the sliding member is connected to the fixed seat. At this time, the first docking member 9 and the second docking member 10 are installed in an interlaced manner. The structure is placed, and the sliding shaft is inserted into the sliding part and the docking part to complete the connection between the sliding part and the docking part, so that the first docking part 9 and the second docking part 10 are respectively connected to the corresponding sliding shafts. After the connection is completed, the torsion shaft is inserted into the other side of the docking part, so that the torsion shaft is connected to the docking part through the fixed seat, thereby completing the connection of the docking parts. At this time, when the fixed seat on one side is rotated, the sliding part under the fixed seat is driven, so that the sliding shaft connected to the sliding part is connected along the second slide groove 18, thereby completing the swing of the fixed seat.
