The connecting plate 406 is slidably connected to the outside of the sliding rod 404 and is symmetrically arranged on both sides of the fixed plate 405.

[0025] Further Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the first spring 407 is fixedly connected between the connecting plate 406 and the rectangular groove 403, and is sleeved on the outside of the sliding rod 404, the sliding block 408 is symmetrically fixedly connected to both sides of the connecting plate 406, and a sliding groove adapted to the sliding block 408 is opened in the middle of the structural cavity 402;

[0026] By setting a slider 408 that is slidably connected to the interior of the structural cavity 402, it can be ensured that when the pressing plate 410 below moves, the connecting plate 406 is stably driven to move, thereby ensuring the stability of the movement of the connecting plate 406.

[0027] Further Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the positioning block 409 is fixedly connected to the right end of the connecting plate 406, and the side of the positioning block 409 away from the fixing tube 401 is arranged on the arc surface, the pressing plate 410 is fixedly connected to the left end of the connecting plate 406, and the front and rear sides of the pressing plate 410 are provided with anti-slip grooves;

[0028] The anti-slip groove is provided to facilitate the user to press the pressing plate 410, thereby improving the practicability of disassembling the counterweight block.

[0029] According to the above working process, it can be known that: through the setting of the connecting mechanism 4, the positioning block 409 can be inserted into the inside of the connecting hole 6, ensuring the connection between the counterweight block body 3 and the connecting ring 2, ensuring the stability of the counterweight block body 3 after installation, and the counterweight block body 3 can be disassembled without external tools, which makes disassembly more convenient and improves work efficiency.

[0030] Further Figure 1 , Figure 2 and Figure 4 As shown, it is worth specifically explaining that the limiting mechanism 5 is composed of a groove 501, a movable plate 502, a second spring 503 and a positioning column 504. The left side of the fixed cylinder 401 is provided with a groove 501, the movable plate 502 is slidably connected to the inside of the groove 501, the second spring 503 is fixedly connected between the movable plate 502 and the inner side of the groove 501, the positioning column 504 is symmetrically connected to the other side of the movable plate 502, and the positioning column 504 is slidably connected between the groove 501 and the rectangular groove 403.

[0031] Further Figure 1 , Figure 2 and Figure 4 As shown, it is worth to explain in detail that a first positioning groove 505 is formed on one side of the pressing plate 410 close to the groove 501, and the shape of the first positioning groove 505 is adapted to the positioning column 504;

[0032] By inserting the positioning column 504 into the first positioning groove 505, it is convenient to fix the position of the pressing plate 410, to disconnect the remaining connection mechanisms 4, and to disassemble the counterweight body 3.

[0034] By inserting the positioning block 409 into the second positioning groove, the counterweight body 3 can be connected to the connecting ring 2. By disengaging the positioning block 409 from the second positioning groove, the connection between the connecting mechanism 4 and the connecting ring 2 is released, making it easy to disassemble the counterweight body 3.

[0035] This solution has the following working process: when in use, align the right end of the fixing tube 401 with the connecting hole 6, and insert the right end of the fixing tube 401 into the interior of the connecting hole 6. The inner wall of the connecting hole 6 squeezes the positioning block 409 until it moves to the second positioning groove inside the connecting hole 6. Under the elastic force of the first spring 407, the positioning block 409 is driven by the connecting plate 406 to be inserted into the interior of the second positioning groove, and the counterweight body 3 and the connecting ring 2 are fixedly connected to ensure the stability of the installation of the counterweight body 3; when the counterweight body 3 needs to be disassembled, the pressing plate 410 is pressed to move the two sides of the fixing plate 405, and the positioning block 409 is driven by the connecting plate 406 to disengage from the interior of the second positioning groove and release the connection with the connecting ring 2. At the same time, under the elastic force of the second spring 503, the positioning column 504 is driven by the moving plate 502 to be inserted into the interior of the first positioning groove 505, and the position of the pressing plate 410 is fixed, so as to facilitate the disconnection of the remaining connecting mechanisms 4 and facilitate the removal of the counterweight body 3.

[0036] In summary: through the setting of the connecting mechanism 4, the positioning block 409 can be inserted into the interior of the connecting hole 6, ensuring the connection between the counterweight body 3 and the connecting ring 2, ensuring the stability of the counterweight body 3 after installation, and the counterweight body 3 can be disassembled without external tools, which makes disassembly more convenient and improves work efficiency; through the setting of the limiting mechanism 5, the pressing plate 410 can be positioned after being pressed, which is convenient for the user to operate other connecting mechanisms 4 in sequence, so that the positioning block 409 is released from the connection with the connecting hole 6, which is convenient for disassembly of the counterweight body 3 and improves the practicality of the counterweight.
