[0028] The technical scheme is applied, the adsorption structure 10 comprises a mounting base 11 and a suction head 12, the mounting base 11 provides a mounting basis for the suction head 12, the mounting base 11 is communicated with an external negative pressure source, the suction head 12 is connected with the mounting base 11 and is communicated, so that the suction head 12 can generate adsorption force to adsorb the cover body 2, the operation structure 20 is connected with the jar body 1, when the operation member is rotated, the jar body 1 is driven to rotate relative to the cover body 2, when the cover body 2 needs to be handled, the suction head 12 adsorbs the cover body 2, so that the position of the cover body 2 can be relatively fixed, the operation structure 20 is connected with the jar body 1 by the worker, the worker operates the operation structure 20, so that the jar body 1 can rotate relative to the cover body 2, so that the cover body 2 is loosened from the jar body 1, which is beneficial to the subsequent worker to align the loosened cover body 2 with the jar body 1 again, on the one hand, the operation of the worker is facilitated, and on the other hand, the cover body 2 is loosened by rotating the cover body 2, so that the cover body 2 is completely retained, the loss of the cover body 2 is reduced, and the production cost is saved. In addition, since the suction head 12 is detachably connected with the mounting base 11, the worker can use different specifications of the suction head to match different specifications of the cover body, thereby increasing the versatility of the cover body screwing assembly. Therefore, the technical scheme of the embodiment can effectively solve the problem that the cover body is difficult to loosen in the related art.

[0029] As shown in Figure 1 and Figure 2 The mounting base 11 comprises a first cylinder 111, the suction head 12 comprises a second cylinder 121 nested with the first cylinder 111, and a connecting structure is arranged between the first cylinder 111 and the second cylinder 121.

[0030] In addition, in the embodiment, the connecting structure comprises a first threaded structure and a second threaded structure matched with each other, the first threaded structure is arranged on the first cylinder 111, and the second threaded structure is arranged on the second cylinder 121. Specifically, the arrangement of the first threaded structure and the second threaded structure can facilitate the mounting and dismounting of the mounting base 11 and the suction head 12, and has the advantages of simple structure and easy processing.

[0031] As shown in Figure 1 and Figure 2As shown, the adsorption structure 10 further comprises a positioning pin 13, the first cylinder 111 is located outside the second cylinder 121, the second cylinder 121 is provided with a positioning hole 14, and the positioning pin 13 is arranged in the first cylinder 111 and the positioning hole 14. Specifically, since the can body 1 needs to be rotated to align the cover body 2 with the can body 1, and the mounting base 11 and the suction head piece 12 are connected by threads, when the can body 1 is rotated, the cover body 2 also has a tendency to rotate, which easily drives the suction head piece 12 to rotate relative to the mounting base 11, so that the suction head piece 12 may be out of threaded connection with the mounting base 11, thereby possibly causing the suction head piece 12 to lose the adsorption force. In order to ensure that the suction head piece 12 and the mounting base 11 can remain stably connected during use, the positioning pin 13 is arranged in the first cylinder 111 and the positioning hole 14, so that even if the second cylinder 121 is subjected to a certain external force, the first cylinder 111 and the second cylinder 121 can remain in a state of stable connection, thereby enabling the suction head piece 12 to continuously have the adsorption force.

[0032] In addition, the cover body screwing assembly further comprises a trigger piece and a switch piece, the switch piece is arranged on the adsorption structure 10, and the trigger piece can make the switch piece connect or disconnect the mounting base 11 and the external negative pressure source when the trigger piece is triggered.

Specifically, the switch piece comprises an electromagnetic valve arranged on the mounting base 11, wherein the trigger piece comprises a control button, the control button is pressed to make the electromagnetic valve connect the mounting base 11 and the external negative pressure source, and the worker can press the control button with his hand to make the electromagnetic valve connect the mounting base 11 and the external negative pressure source, thereby enabling the suction head piece 12 to generate the adsorption force to adsorb the cover body 2. In other embodiments, the trigger piece comprises an infrared sensor, the infrared sensor is triggered to make the electromagnetic valve connect the mounting base 11 and the external negative pressure source, and the worker can block the infrared sensor with his foot, at this time, the infrared sensor cannot receive the infrared signal and is considered to be triggered, so as to make the electromagnetic valve connect the mounting base and the external negative pressure source, thereby enabling the suction head piece to generate the adsorption force to adsorb the cover body.

[0033] As Figure 1 and Figure 3As shown, the operation structure 20 comprises an operation handle 21 and a limiting ring 22, the operation handle 21 is movably arranged, the limiting ring 22 comprises a first ring segment 221 and a second ring segment 222 which are arranged in abutment, the second ring segment 222 is movably arranged relative to the first ring segment 221, the limiting ring 22 has a clamping state and a release state, when the limiting ring 22 is in the clamping state, the second ring segment 222 is close to the first ring segment 221 and clamps the tank body 1 together with the first ring segment 221, when the limiting ring 22 is in the release state, the second ring segment 222 is away from the first ring segment 221 and releases the tank body 1, the operation handle 21 is connected with the second ring segment 222 and can drive the second ring segment 222 to move. It should be noted that "when the limiting ring 22 is in the release state, the second ring segment 222 is away from the first ring segment 221" means that at this time, the radial dimension of the accommodating space formed by the second ring segment 222 and the first ring segment 221 is greater than the radial dimension of the tank body 1, so that the tank body 1 can be released; in this way, the worker can operate the operation handle 21 to switch the state of the limiting ring 22 to clamp or release the tank body 1, and on the other hand, the operation structure 20 can drive the tank body 1 to rotate.

[0034] As shown in Figure 1 and Figure 3 The operation handle 21 comprises an operation segment 211 and a transmission segment 212, the operation segment 211 is hingedly connected with a first end of the first ring segment 221, a second end of the first ring segment 221 is hingedly connected with a first end of the second ring segment 222, a second end of the transmission segment 212 is hingedly connected with the second end of the second ring segment 222, and a second end of the transmission segment 212 is hingedly connected with the operation segment 211, the operation segment 211 can drive the transmission segment 212 to move when rotating, and in turn drive the second end of the second ring segment 222 to move away from or close to the first end of the first ring segment 221. Specifically, the arrangement of the transmission segment 212 can make the operation segment 211 rotate, drive the transmission segment 212 to move, and in turn drive the second ring segment 222 to move, so that the limiting ring 22 switches states, thereby making it convenient for the worker to clamp or release the tank body 1. It should be noted that "move" in this text not only refers to the translational motion state, but also includes the rotational motion state which can cause the position to change.

[0035] As shown in Figure 1 and Figure 3As shown, the operation section 211 is a rod-shaped structure, and the second end of the transmission section 212 is arranged close to the first end of the operation section 211. Specifically, the arrangement that the second end of the transmission section 212 is close to the first end of the operation section 211 means that the distance between the second end of the transmission section 212 and the first end of the operation section 211 is smaller than the distance between the second end of the transmission section 212 and the second end of the operation section 211. The second end of the operation section 211 is a free end. In this way, the worker can make the operation section 211 rotate a smaller stroke to make the transmission section 212 move into position, thereby completing the switching of the state of the limiting ring 22.

[0036] In addition, the inner side of the limiting ring 22 is provided with a flexible protective pad. Specifically, the flexible protective pad is used to protect the tank body 1 to prevent the tank body 1 from being damaged.
