[0033] The end of the clamping jaw 42 away from the sliding piece 3 is used to extend into the ring groove 11 of the weight 1, so that the clamping jaw 42 clamps the weight 1 when it is closed. The end of the clamping jaw 42 towards the sliding piece 3 is used to abut against the sliding piece 3, when the sliding piece 3 abuts against the clamping jaw 42 in the direction of the clamping jaw 42, the second elastic member 43 is compressed and is in a compressed state, the clamping jaw 42 is in a closed state, when the sliding piece 3 moves away from the clamping jaw 42, the compression of the second elastic member 43 is released, the second elastic member 43 is in a reset state, and the clamping jaw 42 is in an open state.

[0034] Specifically, the fixing seat 41 is sleeved on the pulling rod 2, and the fixing seat 41 comprises an annular body 411 sleeved on the pulling rod 2 and a plurality of rotation shaft support frames 412 protruding radially outward from the outer wall of the annular body 411, the clamping jaw 42 is rotationally connected to the rotation shaft support frames 412 through a rotation shaft 44, the clamping jaw 42 can be divided into a first part 422 and a second part 421, the first part 422 is located at the side of the rotation shaft 44 away from the sliding piece 3, and the second part 421 is located at the side of the rotation shaft 44 towards the sliding piece 3, the end of the first part 422 away from the sliding piece 3 extends into the ring groove 11 of the weight 1, and is used to clamp the weight 1 when the clamping jaw 42 is closed, and the end of the second part 421 towards the sliding piece 3 abuts against the sliding piece 3. The second part 421 towards the central axis is provided with the second elastic member 43.

[0035] The rotation direction of the clamping jaw 42 is that when the end of the second part 421 towards the sliding piece 3 expands radially away from the central axis, the end of the first part 422 away from the sliding piece 3 contracts radially towards the central axis; on the contrary, when the end of the second part 421 towards the sliding piece 3 contracts radially towards the central axis, the end of the first part 422 away from the sliding piece 3 expands radially away from the central axis.

[0036] The specific process is as follows: the sliding piece 3 abuts against one end of the second part 421 of the clamping jaw 42 in the direction of the clamping jaw 42, so that the one end of the second part 421 is expanded radially away from the central axis and is limited to be contracted in the direction of the central axis, at this time, the one end of the second part 421 is contracted radially in the direction of the central axis and clamps the weight, and the second elastic piece 43 is compressed and is in a compressed state; when the driving assembly 5 drives the sliding piece 3 to move away from the clamping jaw 42 and compresses the first elastic piece 6, the limitation of the one end of the second part 421 is released, and the limitation of the second elastic piece 43 is also released, the second elastic piece 43 resets, and drives the one end of the first part 422 to be expanded in the direction away from the central axis.

When the barrel is hoisted to the trolley again, the worker unlocks the barrel and the equipment to complete the feeding process. The operator of the present application does not need to approach the barrel to connect the barrel and the weight 1, thereby reducing the risk of injury to the operator when the barrel is broken and improving the operation difficulty and the feeding efficiency.

[0059] Reference Figure 6 and Figure 7 , Figure 7 A cross-sectional view of the weight provided by the embodiment of the present application is shown. In some optional embodiments, the bottom wall of the annular groove 11 is inclined and forms an included angle of less than 90° with the side wall of the annular groove 11, thereby improving the tightness of the clamping jaw 42 after extending into the annular groove 11 and being clamped with the weight 1, and further improving the stability of the connection between the feeding connecting device and the weight 1. At this time, the lower end of the protruding part 4221 of the clamping jaw 42 is provided with an inclined surface that is in abutment with the bottom wall of the annular groove 11, thereby further improving the tightness and stability of the clamping jaw 42 and the weight 1.

[0060] The technical features of the above embodiments can be combined in any manner. In order to make the description concise, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present application.

[0061] The above embodiments only express several implementation manners of the application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which all belong to the protection scope of the application. Therefore, the protection scope of the patent of the application should be subject to the appended claims.
