[0041] like Figure 1 - Figure 4 As shown, the clamping mechanism provided by the present invention includes: a power part connection structure, a fixed part connection structure, a movable arm 14 and a connecting arm.

[0042] The power part connection structure is connected to the driving mechanism, and the driving mechanism is used to drive the movable arm 14 to open and close through the power part connection structure. When the movable arm 14 opens and closes, the fixed part connection structure remains in a fixed position in space.

[0043] The movable arm 14 is detachably connected to the power unit connection structure.

[0044] The power part connection structure may include a connector 12, a limiter 11 and a magnetic rod 10. All of the movable arms 14 are connected to the connector 12. The number of movable arms 14 may be two, three, four or more. In this embodiment, the number of movable arms 14 is three, and the corresponding connector 12 is roughly triangular in shape, and the movable arms 14 are connected to the corners of the connector 12. The shape of the limiter 11 is also roughly triangular, and the limiter 11 is connected to the top surface of the connector 12. The limiter 11 is used to limit the rotation range of the movable arm 14 to prevent it from opening too wide. The magnetic rod 10 is located above the limiter 11, and a second screw 13 can be used to pass through the connector 12, the limiter 11 and the magnetic rod 10 in sequence to connect the three. The magnetic rod 10 is used to connect to the driving mechanism.

[0045] The rear end of the movable arm 14 is provided with an axial hole extending through its left and right side walls. The clamping mechanism also includes a threaded rod, such as a locking bolt 15. The connector 12 is provided with a connecting seat, which includes two first lugs spaced apart, each of which is provided with a first screw hole. The movable arm 14 is positioned between the two first lugs. The threaded rod passes through the axial hole and is threadedly connected to both first screw holes.

[0046] The fixing portion connection structure includes a claw tube 1, a fixing ring 2, and a fixing member 4. The number of fixing members 4 is the same as the number of connecting arms, and they correspond one to one. The connecting arms are connected to the outer wall of the fixing member 4, and the claw tube 1 is connected to the inner side of the fixing member 4. The fixing member 4 and the fixing ring 2 are detachably connected to facilitate component replacement.

[0047] The fixing member 4 is roughly shaped like a [, and comprises an upper jaw, an intermediate transition portion, and a lower jaw, which are connected in sequence. The upper and lower jaws respectively engage the upper and lower edges of the fixing ring 2 to prevent the fixing member 4 from moving up and down. The intermediate transition portion is provided with a second lug, and the connecting shaft is rotatably connected to the second lug. The intermediate transition portion is also provided with a mounting hole, and the fixing ring 2 is provided with a third screw hole. A first screw 8 is passed through the mounting hole and then threadedly connected to the third screw hole, thereby locking the fixing member 4 to the fixing ring 2.

[0048] The third screw 3 can be used to pass through the fixing ring 2 and abut against the outer wall of the claw tube 1, so as to lock and fix the claw tube 1 and the fixing ring 2 together.

[0049] The movable arm 14 is provided with a pin hole. The connecting arm includes a fixed arm 6 and a movable arm 5 with a gap provided therebetween, and the gap is used to accommodate the movable arm 14. The upper end of the fixed arm 6 is provided with a first connecting hole, and the lower end of the fixed arm 6 is provided with a pin shaft protruding toward one side of the movable arm 5, and the pin shaft is used to connect with the pin hole. The upper end of the movable arm 5 is provided with a second connecting hole, and the lower end of the movable arm 5 is provided with a first locking hook. The first connecting hole and the second connecting hole are both rotatably connected to the second ear plate via a connecting shaft, and the pin shaft is located on the movement path of the first locking hook. When the movable arm 5 rotates to coincide with the fixed arm 6, the first locking hook and the pin shaft are connected together. The connecting shaft can be a rivet 7.

[0050] The locking mechanism includes a knob 9 and a screw, one end of which is coaxially connected to the knob 9. A second screw hole is provided on the fixed arm 6, and the screw is threadedly connected to the second screw hole. By rotating the knob 9, the distance between the knob 9 and the fixed arm 6 can be changed. A second locking hook is provided on the movable arm 5, and the screw is located in the movement path of the second locking hook. When it is necessary to lock the fixed arm 6 and the movable arm 5, the user can rotate the knob 9 so that the knob 9 and the fixed arm 6 are used to clamp the movable arm 5, so that the movable arm 5 is fixed relative to the fixed arm 6. Rotating the knob 9 in the opposite direction can release the movable arm 5, facilitating the disassembly of the movable arm 14.

[0051] During installation, the movable arm 5 can be rotated around the connecting axis by an angle so that the fixed arm 6 and the movable arm 5 are staggered. Then, the pin hole on the movable arm 14 is aligned with the pin shaft on the fixed arm 6 and the movable arm 14 is inserted. Then, the movable arm 5 is rotated in the opposite direction until the first locking hook on it is connected to the pin shaft. Then, the locking mechanism is used to lock the fixed arm 6 and the movable arm 5. The fixed arm 6 and the movable arm 5 clamp the movable arm 14. The movable arm 14 cannot fall out and can rotate around the pin shaft. Finally, the movable arm 14 is connected to the power unit connection structure. The connection points associated with replacing the movable arm 14 are all movable connections and easy to operate. There is no need to replace the entire clamping jaw to replace the movable arm 14, which saves costs.

[0052] The doll grabbing machine provided by the present invention includes the above-mentioned clamping mechanism. Since the doll grabbing machine provided by the present invention adopts the above-mentioned clamping mechanism, the doll grabbing machine provided by the present invention also has the advantages of the clamping mechanism.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
