Referring to fig. 1, the front cable 600 is positioned at the left side of the balance weight 200, the left rear cable 300 and the right rear cable 400 are positioned at the right side of the balance weight 200, and the "balance weight 200 is in a balanced state" is that both ends of the balance weight 200 are not inclined in the case that the lengths of the left rear cable 300 and the right rear cable 400 are identical, as shown in fig. 1, the lower end of the balance weight 200 is inclined to the left and down, the balance weight 200 is in an unbalanced state, as shown in fig. 2, both ends of the balance weight 200 are arranged in the vertical direction, and the balance weight 200 is in a balanced state.

When the balance weight 200 is inclined, according to the inclination, the adjusting gasket 500 is embedded between the first limiting boss 330 and the mounting plate, or between the second limiting boss 410 and the mounting plate, or between the first limiting boss 330 and the mounting plate, or between the second limiting boss 410 and the mounting plate, so that the balance weight 200 can be pulled to be in an unbalanced state, and the left rear cable 300 and the right rear cable 400 are stressed consistently. For example, referring to fig. 1, the left rear stay 300 is positioned below the right rear stay 400, and when the lower end of the weight 200 is inclined downward and leftward, the adjustment shims 500 are fitted between the first stopper boss 330 of the left rear stay 300 and the mounting plate, and when the deviation of the left rear stay 300 is relatively large, two to three adjustment shims 500 are mounted, and when the deviation of the left and right is relatively small, one adjustment shim 500 is mounted. For another example, in the case that the lower end of the weight 200 is inclined downward to the right, the adjusting pad 500 is inserted between the second limit boss 410 of the right rear cable 400 and the mounting plate until both ends of the weight 200 are in a balanced state, as shown in fig. 2.

Referring to fig. 3, 4, 5 and 6, in the present embodiment, the adjusting pad 500 is provided with an embedded round hole 510 and an embedded opening 520 communicating with the embedded round hole 510; the embedded opening 520 is used for embedding the left back cable 300 or the right back cable 400 into the embedded round hole 510, and is used for preventing the left back cable 300 or the right back cable 400 from exiting from the embedded round hole 510, and the embedded round hole 510 is used for being embedded with the left back cable 300 or the right back cable 400.

After the left rear stay cable 300 or the right rear stay cable 400 is clamped into the embedded round hole 510 through the embedded opening 520, the left rear stay cable 300 or the right rear stay cable 400 can be in clearance fit or interference fit with the embedded round hole 510, and cannot withdraw from the embedded opening 520.

Referring to fig. 3, 4, 5 and 6, in the present embodiment, the width of the embedded opening 520 is smaller than the diameter of the embedded circular hole 510. Specifically, the embedded round hole 510 of the adjusting gasket 500 is used to be sleeved at the position represented by the dimension mark a in fig. 4, and then is installed between the mounting plate and the limiting boss shown in fig. 3. Because the size of the embedded round hole 510 matches the diameter of the position represented by the dimension mark a, the size of the embedded opening 520 is smaller than the size of the embedded round hole 510, and therefore, the size of the embedded opening 520 is smaller than the position represented by the dimension mark a, and the adjusting gasket 500 cannot fall after being embedded in the position represented by the dimension mark a.

Referring to fig. 3, 4, 5 and 6, in the present embodiment, a first cable segment 310, a second cable segment 320 and a first limit boss 330 are sequentially disposed on a left rear cable 300 along an axial direction; the diameters of the first cable segment 310, the second cable segment 320 and the first limit boss 330 are gradually increased; the first cable segment 310 is used for allowing the left rear cable 300 to be clamped into the embedded round hole 510 from the embedded opening 520, and the second cable segment 320 is used for being embedded with the embedded round hole 510.

After the first cable segment 310 is clamped into the embedded round hole 510 from the embedded opening 520, the adjusting gasket 500 is moved to the second cable segment 320 along the axial direction, so that the embedded round hole 510 of the adjusting gasket 500 is sleeved with the second cable segment 320, and the second cable segment 320 cannot fall out from the embedded opening 520 because the diameter of the second cable segment 320 is larger than that of the embedded opening 520. Meanwhile, due to the clamping connection between the mounting plate and the first limiting boss 330, the adjusting gasket 500 cannot axially move, and therefore cannot fall out.

Similarly, in this embodiment, the right rear cable 400 is sequentially provided with a third cable segment, a fourth cable segment and a second limiting boss 410 along the axial direction; the diameters of the third cable segment, the fourth cable segment and the second limiting boss 410 are gradually increased; the third cable segment is used for enabling the right rear cable 400 to be clamped into the embedded round hole 510 from the embedded opening 520, and the fourth cable segment is used for being embedded with the embedded round hole 510.

After the third cable section is clamped into the embedded round hole 510 from the embedded opening 520, the adjusting gasket 500 is moved to the fourth cable section along the axial direction, so that the embedded round hole 510 of the adjusting gasket 500 is sleeved with the fourth cable section, and the fourth cable section cannot fall out from the embedded opening 520 because the diameter of the fourth cable section is larger than that of the embedded opening 520. Meanwhile, due to the clamping connection between the mounting plate and the second limiting boss 410, the adjusting gasket 500 cannot axially move, and therefore cannot fall out.

In this embodiment, the adjusting pad 500 is square, and the thickness of the adjusting pad 500 is 0.8-1.2mm. The thickness of the adjustment shim 500 is 0.8mm, 0.9mm, 1mm, or 1.2mm. Two to three adjusting shims 500 are installed when the deviation of the left rear stay 300 is large, one adjusting shim 500 is installed when the deviation of the left and right is small, or none is installed.

Referring to fig. 2 and 3, in the present embodiment, the mounting plate is provided with a first opening communicating with the first mounting hole; the first opening is used for the first cable section 310 to clamp into a first mounting hole, and the first mounting hole is used for being embedded with a second cable section 320.

During installation, the first cable segment 310 is clamped into the first installation hole, and then the left rear cable 300 is axially moved, so that the second cable segment 320 is clamped into the first installation hole. Because the diameter of the first limiting boss 330 is greater than that of the first mounting hole, after the left rear cable 300 is connected to the balance weight 200, the left rear cable 300 is tensioned, and the first limiting boss 330 abuts against the outside of the mounting plate. Thereby adding the adjusting pad 500 between the mounting plate and the first limiting boss 330, the weight 200 can be pulled from an unbalanced state to a balanced state.

When the adjusting spacer 500 is additionally installed, the left back guy cable 300 can be removed from the balance weight 200, then the adjusting spacer 500 is clamped on the second guy cable section 320, then the left back guy cable 300 is installed on the first installation hole, and then the left back guy cable 300 is fixedly connected with the balance weight 200, so that the position of the balance weight 200 is adjusted to a balance state.

Similarly, in this embodiment, the mounting plate is provided with a second opening communicating with the second mounting hole; the second opening is used for enabling the third cable section to be clamped into the second mounting hole, and the second mounting hole is used for being embedded with the fourth cable section.

Similarly, the first cable segment 310 is first snapped into the second mounting hole and then the right rear cable 400 is axially moved to snap the second cable segment 320 into the second mounting hole. Since the diameter of the second limiting boss 410 is larger than that of the second mounting hole, after the right rear cable 400 is connected to the weight 200, the right rear cable 400 is tensioned, and the second limiting boss 410 abuts against the outside of the mounting plate. Thereby adding the adjusting spacer 500 between the mounting plate and the second limiting boss 410, the balance weight 200 can be pulled from an unbalanced state to a balanced state.

When the adjusting spacer 500 is additionally installed, the right back guy cable 400 can be removed from the balance weight 200, then the adjusting spacer 500 is clamped on the second guy cable section 320, then the right back guy cable 400 is installed on the second installation hole, and then the right back guy cable 400 is fixedly connected with the balance weight 200, so that the position of the balance weight 200 is adjusted to a balance state.
