wherein the target carrier comprises a bearing bracket for bearing the hanging bracket;

wherein the connecting portion on the hanging bracket comprises a supporting shaft arranged on the hanging bracket, and the bearing bracket is provided with a groove for placing therein the supporting shaft.

2. The target mounting fixture according to claim 1 , wherein

the moving unit comprises a first moving mechanism for moving the target carrier along a first horizontal direction and a second horizontal direction perpendicular to each other.

3. The target mounting fixture according to claim 2 , wherein the first moving mechanism comprises:

a lateral bearing working table;

a first guide rail arranged on the lateral bearing working table and extending along the first horizontal direction;

a first bearing plate capable of moving on the first guide rail;

a second guide rail arranged on the first bearing plate and extending along the second horizontal direction; and

a second bearing plate capable of moving on the second guide rail;

wherein the target carrier is arranged on the second bearing plate through the first moving mechanism.

4. The target mounting fixture according to claim 3 , wherein

the moving unit comprises a second moving mechanism for moving the target carrier along a vertical direction perpendicular to both the first horizontal direction and the second horizontal direction,

the second moving mechanism comprises:

a first side wall arranged on the second bearing plate, the first side wall being provided with a third guide rail extending along the vertical direction;

a sliding block connected to the target carrier and capable of moving on the third guide rail; and

a driving portion for driving the sliding block to move on the third guide rail.

5. The target mounting fixture according to claim 4 , wherein the driving portion comprises:

a pulley block at least comprising one fixed pulley;

a first rotating portion; and

a steel wire wound around the pulley block, one end of the steel wire being connected to the sliding block, and the other end being wound around the first rotating portion;

wherein the first rotating portion is capable of rotating to stretch the steel wire to drive the sliding block to move on the third guide rail.

6. The target mounting fixture according to claim 3 , wherein

the moving unit further comprises a third moving mechanism for rotating the target carrier in a vertical plane perpendicular to a horizontal plane.

7. The target mounting fixture according to claim 6 , wherein the third moving mechanism comprises:

a first side wall and a second side wall arranged opposite to each other on the second bearing plate, wherein the target carrier is mounted on the first side wall, one end portion of the first side wall and the second bearing plate are connected to each other through a pivot, the first side wall is rotatable around the pivot, and the second side wall is perpendicular to the second bearing plate; and

a screw rod rotatably mounted in the second side wall, one end of the screw rod being connected to the first side wall, and the other end of the screw rod being provided with a second rotating portion; wherein the screw rod is configured to drive the first side wall to rotate around the pivot through rotating the second rotating portion.

8. The target mounting fixture according to claim 3 , wherein

the target mounting fixture further comprises a high-altitude platform apparatus for an operator to perform a high-altitude operation, and the high-altitude platform apparatus is connected to the lateral bearing working table.
