[0074] In some embodiments of the present application, the first mounting position 111 and the second mounting position 112 are formed on the converter body 110.

[0075] The first connecting part 120 includes a first connecting shaft 121 and a second connecting shaft 122.

[0076] The first connecting shaft 121 is mounted at the first mounting position 111.

[0077] The second connecting shaft 122 is mounted at the second mounting position 112.

[0078] Specifically, the first mounting position 111 can be a first mounting hole.

[0079] Specifically, the second mounting position 112 can be a second mounting hole.

[0080] In some embodiments of the present application, the converter body 110 comprises two oppositely arranged support plates 113. The two support plates 113 are arranged in parallel.

[0081] The first mounting position 111 is arranged through the two support plates 113.

[0082] The second mounting position 112 is arranged through the two support plates 113.

[0083] The first mounting position 111 and the second mounting position 112 form an accommodating cavity 114 therebetween. The swing part is installed in the accommodating cavity 114.

[0084] The first connecting shaft 121 and the second connecting shaft 122 are used for connecting with the excavator.

[0085] The excavator converter is connected with the excavator through the first connecting shaft 121 and the second connecting shaft 122.

[0086] In some embodiments of the present application, a third mounting position 211 is formed on the converter body 110. The second connecting part 220 is installed at the third mounting position 211.

[0087] The swing part body 210 and the second connecting part 220 are rotatably connected.

[0088] A rotating hole 212 is formed on the swing part body 210, and the rotating hole 212 is sleeved outside the second connecting part 220, so that the swing part body 210 and the second connecting part 220 are rotatably connected.

[0089] The driving part 300 drives the swing part body 210 to rotate around the second connecting part 220.

[0090] The driving part 300 comprises a driving fixed end 310 and a driving output end 320.

[0091] The driving fixed end 310 is rotatably connected with the second connecting shaft 122.

[0092] The driving output end 320 is connected with the swing part body 210, so as to drive the swing part body 210 to rotate around the second connecting part 220.

[0093] Specifically, the driving part 300 can adopt an oil cylinder.

[0094] Specifically, the first clamping part 130 can adopt a first arc-shaped structure 131, and the first arc-shaped structure 131 is formed with a first opening 132.

[0095] Specifically, the second clamping portion 230 can adopt a second arc-shaped structure 231, and the second opening 232 is formed on the second arc-shaped structure 231.

[0096] The first opening 132 and the second opening 232 are oppositely arranged. Specifically, the first opening 132 and the second opening 232 are arranged on the side away from the first arc-shaped structure 131 and the second arc-shaped structure 231.

[0097] In some embodiments of the present application, when the driving portion 300 drives the second clamping portion 230 to move away from the first clamping portion 130 to the position where the first clamping portion 130, the second clamping portion 230 and the tool are connected, the first clamping portion 130 and the second clamping portion 230 are clamped to the tool in opposite directions. In order to avoid the situation that the driving portion 300 fails, a locking portion is arranged. The locking portion is used to lock the relative position between the swing portion and the fixed portion.

[0098] Specifically, the first clamping portion 130 and the second clamping portion 230 are clamped to the tool in a way that the first opening 132 and the second opening 232 are arranged on both sides. Since the tool is used as a support, in the case that the driving portion 300 fails, the first clamping portion 130 and the second clamping portion 230 will not move away from each other.

[0099] In addition, since the first clamping portion 130 and the second clamping portion 230 are in a state of being pushed away from each other by the driving portion 300, in the case that the driving portion 300 fails abnormally, the first clamping portion 130 and the second clamping portion 230 are less likely to move away from each other in the absence of external force.

[0100] In order to avoid the situation that the second clamping portion 230 moves close to the first clamping portion 130 in the case that the driving portion 300 fails, a locking portion is arranged.

[0101] The locking portion includes a first stop portion 410 and a second stop portion 420. The first stop portion 410 is arranged on the fixed portion. The second stop portion 420 is arranged on the swing portion. The first stop portion 410 is used to stop the second stop portion 420, so as to prevent the first stop portion 410 and the second stop portion 420 from moving close to each other.

[0102] Specifically, the first stop portion 410 includes a stop shaft. The stop shaft is connected to the fixed portion, and the stop shaft is arranged in parallel with the second connecting portion 220.

[0103] Specifically, the second stop portion 420 includes an arc-shaped portion. The arc-shaped portion surrounds the stop shaft.

[0104] In the state that the first clamping part 130 and the second clamping part 230 are close to each other, the arc-shaped part abuts against the stop shaft, thereby stopping the further relative close of the first clamping part 130 and the second clamping part 230.

[0105] In some embodiments of the present application, the fixing part is provided with a connecting hook 140 for hooking the goods.

[0106] The above structure is used to replace the tool, only the action of the driving part 300 needs to be controlled, the distance between the first clamping part 130 and the second clamping part 230 is controlled to disassemble, replace and install the tool, the converter body 110 is connected with the excavator by providing the first connecting part 120 on the converter body 110, the swing part body 210 is rotatably connected with the converter body 110 by providing the second connecting part 220 on the converter body 110, the first clamping part 130 is provided on the converter body 110, the second clamping part 230 is provided on the swing part body 210, the driving part 300 drives the first clamping part 130 and the second clamping part 230 to relatively move away to clamp the tool, the quick connection of the excavator with the tool through the excavator converter is realized, when the tool needs to be replaced, the driving part 300 drives the first clamping part 130 and the second clamping part 230 to relatively move close to loosen the tool, then the tool is replaced, thereby the labor intensity of the tool replacement process is low, the number of workers required for operation is reduced, and the tool replacement efficiency is improved.

[0107] In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0108] The above merely describes specific implementation manners of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application, therefore, the protection scope of the present application should be subject to the protection scope of the claims.
