Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1

[0023] Please refer to Figures 1 to 4 , an auxiliary device for installing a chain of an agricultural machinery device, including a base 1. Connecting arms 2 are rotatably connected to both sides of the base 1. A connecting shaft 3 is rotatably connected to the inner side of the connecting arm 2. A clamping plate 4 is fixedly connected to one side of the connecting shaft 3. An adjusting screw 5 is threadedly connected to the inside of the base 1. A sliding sleeve 6 is rotatably connected to one end of the adjusting screw 5. The sliding sleeve 6 is slidably connected to the connecting arm 2. A connecting handle 7 is slidably connected to the inside of the adjusting screw 5. A pressing plate 8 is slidably connected to the inside of the adjusting screw 5. A connecting mechanism is fixedly connected to one side of the pressing plate 8.

[0024] The connecting mechanism includes a spring 901. One end of the spring 901 is fixedly connected to the inner wall of the adjusting screw 5. A connecting frame 902 is fixedly connected to the side wall of the pressing plate 8. An adjusting button 903 is fixedly connected to one side of the connecting frame 902.

[0025] An annular groove 904 is formed on the outer side of the connecting handle 7. The number of the annular grooves 904 is several, and several annular grooves 904 are equidistantly distributed. One end of the pressing plate 8 extends into the annular groove 904.

[0026] A sliding groove 10 is provided at the bottom of the adjustment button 903, and a limiting column 11 is slidably connected inside the sliding groove 10. One end of the limiting column 11 is fixedly connected to the inner wall of the adjustment screw 5.

[0027] By providing the sliding groove 10 and the limiting column 11, when the adjustment button 903 moves up and down, the limiting column 11 can play a limiting role on it, preventing the adjustment button 903 from shaking during movement and causing movement jamming.

[0028] The working principle of this embodiment: When the chain of the agricultural machinery equipment breaks, a new link needs to be installed between the two broken chains for repair. At this time, move the base 1 so that the two clamping plates 4 at the bottom of the base 1 are respectively inserted into the holes of the two broken chains. Subsequently, rotate the connection handle 7, and the connection handle 7 drives the adjustment screw 5 to rotate. After the adjustment screw 5 rotates, it moves towards the side close to the chain inside the base 1. Subsequently, the adjustment screw 5 drives the sliding sleeve 6 to move towards the side close to the chain, so that the sliding sleeve 6 pushes the two connecting arms 2 towards each other. The two connecting arms 2 moving towards each other will drive the two clamping plates 4 towards each other. At this time, since the end of the clamping plate 4 is inserted into the hole of the broken chain, the clamping plates 4 moving towards each other will pull the two chains towards each other. The distance between the two chains after approaching is shortened, which is convenient for inserting a new chain into it, and thus the repair of the entire chain is completed;

[0029] During the rotation of the connection handle 7, since it is slidably connected to the adjustment screw 5, during the rotation of the connection handle 7, the connection handle 7 is likely to loosen and fall off from the adjustment screw 5, which will affect the repair efficiency of the chain. By providing the pressing plate 8, the pressing plate 8 is located inside the annular groove 904 outside the connection handle 7, so that the pressing plate 8 restricts the connection handle 7 and prevents the connection handle 7 from falling off from the adjustment screw 5, ensuring that it will not affect the repair of the broken chain;

[0030] When it is necessary to adjust the position of the connection handle 7 in the adjustment screw 5, press down the adjustment button 903. The adjustment button 903 drives the pressing plate 8 to move downward through the connecting frame 902, so that the pressing plate 8 moves downward out of the annular groove 904. At this time, the connection handle 7 can be slid left and right to adjust its position in the adjustment screw 5. After the adjustment is completed, release the adjustment button 903. Under the elastic force of the spring 901, the pressing plate 8 moves upward into the annular groove 904 outside the connection handle 7 and fixes the connection handle 7 again.

[0031] Embodiment Two

[0032] This embodiment is an improvement made on the basis of Embodiment One. Specifically, please refer to Figures 1 to 4 , a worm gear 12 is fixedly connected to the outside of the connecting shaft 3, and a worm 13 is meshed and connected to one side of the worm gear 12.

[0033] One end of the worm 13 is rotatably connected to a fixed frame 14, and the fixed frame 14 is fixedly connected to the inner wall of the clamping plate 4.

[0034] The other end of the worm 13 is fixedly connected to an adjustment knob 15. The outer side of the worm 13 is rotatably connected to a fixed sleeve 16, and the fixed sleeve 16 is fixedly connected to the inner wall of the clamping plate 4.

[0035] By providing the adjustment knob 15, the worm 13 and the worm gear 12, when the adjustment knob 15 is rotated, it drives the worm 13 to rotate. The worm 13 drives the worm gear 12 to rotate. The worm gear 12 drives the connecting shaft 3 to rotate. The connecting shaft 3 drives the clamping plate 4 to rotate around the connecting shaft 3, thereby adjusting the angle between the clamping plate 4 and the connecting arm 2. By adjusting the angle between the two, the practicability of the clamping plate 4 can be improved to adapt to chains of different specifications.

[0036] A support column 17 is sleeved inside the spring 901, and one end of the support column 17 is fixedly connected to the inner wall of the adjusting screw 5.

[0037] By providing the support column 17, the support column 17 plays a supporting role inside the spring 901, making the spring 901 not easily deformed after long-term use.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0039] The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
