[0034] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below. Example 1

[0035] In this embodiment of the present application, refer to Figure 1-Figure 6 As shown, an anti-overload protection structure of an automatic capping device is provided, including a capping device push-pull rod 1, one end of the capping device push-pull rod 1 is connected to a capping device clamp assembly 2, one end of the capping device push-pull rod 1 is slidably inserted into the capping device clamp assembly 2, and the capping device push-pull rod 1 drives the capping device clamp assembly 2 to clamp and release through its own push-pull and telescopic movement. The capping device push-pull rod 1 is provided with two sections, including a first rod body 11 and a second rod body 12, and an anti-overload protection structure assembly 3 is connected between the first rod body 11 and the second rod body 12.

[0036] The anti-overload protection structure assembly 3 includes a plurality of support arms 31, and the plurality of support arms 31 are in a diamond-shaped distribution structure. Two ends of the support arms 31 of the diamond-shaped distribution structure are respectively hinged to the first rod body 11 and the second rod body 12, and the other two ends of the support arms 31 of the diamond-shaped distribution structure are respectively hinged to a support seat 32. The support seat 32 is slidably connected to a limit rod 39, and the limit rod 39 slides through the middle of the support seat 32, and can form a restriction from the middle of the support seat 32, so that the force on the support seat 32 is more uniform and stable when sliding, and a first clamping block 33 is provided on one side of the support seat 32, and a second clamping block 34 is correspondingly provided on one side of the first clamping block 33, and the second clamping block 34 is fixedly connected to the fixing seat 35.

[0037] The first clamping block 33 and the second clamping block 34 are provided with matching arc-shaped clamping structures, one side of the first clamping block 33 is provided with an arc-shaped groove structure, and one side of the second clamping block 34 is an arc-shaped convex structure, and the arc-shaped convex structure matches the arc-shaped groove structure; when the first clamping block 33 and the second clamping block 34 are in the clamping state, the support seat 32 cannot slide along the limit rod 39, and the push-pull rod 1 of the sealing device can be pushed out normally and stably. When the push-pull rod 1 of the sealing device is pushed out, the resistance encountered is too large, exceeding the clamping force of the first clamping block 33 and the second clamping block 34, which will cause the first clamping block 33 and the second clamping block 34 on the support seat 32 to be out of the clamping state, so that the overload resistance encountered by the second rod body 12 will not continue to be transmitted to the first rod body 11, thereby protecting the transmission mechanism and the power device at the rear end, thereby achieving the purpose of overload prevention. Example 2

[0038] This second embodiment is a further improvement on the first embodiment. Figure 1-Figure 6 As shown, in order to enable the first clamping block 33 and the second clamping block 34 to automatically reset after being disengaged, a spring 37 is provided on the side support of the support seat 32 away from the support arm 31, and the spring 37 is sleeved on the limit rod 39; the spring 37 can push the support seat 32, and under normal conditions, the action force of the spring 37 can cooperate with the clamping action force of the first clamping block 33 and the second clamping block 34 to jointly form a limiting effect on the support seat 32, and after the first clamping block 33 and the second clamping block 34 are disengaged, the spring 37 can push the first clamping block 33 to reset, thereby achieving automatic reset.

[0039] An adjusting piece 36 is slidably connected to the fixing seat 35 as shown. A round hole is provided in the middle of the adjusting piece 36, and a limiting rod 39 slides through the round hole. The limiting rod 39 can limit the adjusting piece 36 to improve the sliding stability of the adjusting piece 36. The end of the spring 37 away from the supporting seat 32 is connected to the adjusting piece 36. The position of the adjusting piece 36 can be changed by sliding, so that the spring 37 can be squeezed and the elastic force of the spring 37 can be adjusted. Firstly, it can avoid the insufficient elastic force of the spring 37 after fatigue, and secondly, the elastic force can be adjusted accordingly according to the actual situation.

[0040] A nut 38 is provided on one side of the adjusting plate 36, and the nut 38 is sleeved on the limiting rod 39, and the nut 38 cooperates with the thread on the limiting rod 39; by screwing the nut 38 to adjust the position on the limiting rod 39, the adjusting plate 36 can be squeezed and pushed, so that the adjusting plate 36 can remain stable at any time after the position is adjusted. Example 3

[0041] This embodiment 3 is a further improvement on the basis of the embodiment 1. Figure 1 Figure 2 and Figure 6As shown, in order to enable the first clamping block 33 and the second clamping block 34 to reset more smoothly after separation, the first clamping block 33 is rotatably connected to the support seat 32, so that when the support seat 32 is reset, the first clamping block 33 can rotate upward and then stagger with the second clamping block 34, which helps to achieve automatic reset. When the reset distance of the first clamping block 33 exceeds the position of the second clamping block 34, the lower part of the first clamping block 33 loses the support of the second clamping block 34 and can rotate downward, and is completely reset to a state where its arc groove structure faces downward. When the support seat 32 continues to move to the right, the first clamping block 33 and the second clamping block 34 can be clamped together again.

[0042] Working principle: Under normal circumstances, the first clamping block 33 and the second clamping block 34 are in a clamping state, and the support seat 32 cannot slide along the limit rod 39, which limits the distance between the first rod body 11 and the second rod body 12 and will not shorten it, so that the push-pull rod 1 of the capping device can be pushed out normally and stably. When the push-pull rod 1 of the capping device is pushed out, the resistance it encounters is too large, exceeding the clamping force of the first clamping block 33 and the second clamping block 34, and the second rod body 12 is subjected to a reverse thrust force in the direction of the first rod body 11, which will push the support seat 32 to slide through the hinged support arm 31, so that the first clamping block 33 and the second clamping block 34 on the support seat 32 are out of the clamping state, so that the overload resistance of the second rod body 12 will not continue to be transmitted to the first rod body 11, thereby protecting the transmission mechanism and power device at the rear end, thereby achieving the purpose of overload prevention.

[0043] The above are only preferred embodiments of the present application, and do not constitute any formal limitation on the present application. Any technician familiar with the art can use the above disclosed methods and technical contents to make many possible changes and modifications to the technical solution of the present application without departing from the scope of the technical solution of the present application, or modify it into an equivalent embodiment of equivalent changes. Therefore, all equivalent changes made according to the shape, structure and principle of the present application without departing from the content of the technical solution of the present application should be included in the protection scope of the present application.
