[0036] When in use, first fix the fixing sleeve 4011 on the mounting block 3, then set the mounting sleeve 4012 inside the fixing sleeve 4011, so that the rotating plate 4013 and the rotating sleeve 4014 can rotate around the side wall of the mounting sleeve 4012, and when the position of the elastic clip 4023 needs to be adjusted, the threaded rod 4017 is rotated, and since the threaded rod 4017 is meshed and connected with the teeth 4015 on the rotating sleeve 4014, the rotating sleeve 4014 can drive the rotating plate 4013 to rotate. When the rotating plate 4013 rotates, the sliding groove 4018 on the rotating plate 4013 can squeeze the sliding block 4019, so that the sliding block 4019 moves in the sliding groove 4018, thereby realizing the movement of the elastic clip 4023, wherein the fixed block 4016 can not only install the threaded rod 4017, but also support the rotating plate 4013, so that the rotating plate 4013 rotates on the fixed block 4016, when the sliding block 4019 moves in the sliding groove When the groove 4018 moves, the sliding plate 4022 can be driven to move in the moving groove 4021, and then the elastic clip 4023 can be driven to move, until the elastic clip 4023 contacts the inner wall of the circular cup-shaped workpiece and can no longer move.

When the position of the elastic clip 4023 needs to be adjusted, the threaded rod 4017 is rotated. Since the threaded rod 4017 is meshed and connected with the teeth 4015 on the rotating sleeve 4014, the rotating sleeve 4014 can drive the rotating plate 4013 to rotate. When the rotating plate 4013 rotates, the sliding groove 4018 on the rotating plate 4013 can squeeze the sliding block 4019. , so that the sliding block 4019 moves in the sliding groove 4018, thereby realizing the movement of the elastic clip 4023, wherein the fixed block 4016 can not only install the threaded rod 4017, but also support the rotating plate 4013, so that the rotating plate 4013 rotates on the fixed block 4016, and when the sliding block 4019 moves in the sliding groove 4018, it can drive the sliding plate 4022 to move in the moving groove 4021, thereby driving the elastic clip 4023 to move, until the elastic clip 4023 contacts the inner wall of the round cup-shaped workpiece and cannot move any further, at this time, the elastic clip 4023 can move the round cup-shaped workpiece The workpiece is clamped and fixed, and the cross section of the elastic clip 4023 is set in a "[" shape, and the corner is set in an arc shape, which avoids the top of the elastic clip 4023 from damaging the inner wall of the round cup-shaped workpiece. When the sliding plate 4022 moves in the moving groove 4021, the limited plate 5 and the limited groove 6 are used in combination to make the sliding instinct move more stably. Then the rotating rod 7 is connected to the threaded rod 4017, and the rotating handle 8 can drive the rotating rod 7 to rotate, thereby rotating the threaded rod 4017, thereby facilitating the movement of the elastic clip 4023. Then the mounting ear 9 and the mounting bolt 10 are used in combination to fix the fixing sleeve 4011 It is fixedly installed on the fixed block 4016, and then the fixing hole 11 and the fastening bolt 12 are used in combination to fix the mounting block 3 at different positions in the placement groove 2. Then, when the mounting block 3 moves in the placement groove 2, the friction between the mounting block 3 and the placement groove 2 can make the rotating roller 14 rotate in the rotating groove 13, thereby reducing the friction between the mounting block 3 and the placement groove 2. Then, the rubber protective pad 15 can further prevent the elastic clip 4023 from damaging the inner wall of the round cup-shaped workpiece. Then, the reinforcing rib 16 is arranged between the middle and lower part of the elastic clip 4023 and the sliding plate 4022, which can improve the stability of the elastic clip 4023.
