[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 3, the utility model provides an embodiment: a powder metallurgy connecting rod assembly, including a fixed rod 1 and a second assembly 3, one side of the fixed rod 1 is fixedly connected to the first assembly 2, the first assembly 2 is fixedly connected with a fixed column 4, one end of the fixed column 4 is fixedly connected to a connecting column 6, the outer wall of the connecting column 6 is slidably connected with a slider 5, a slot 12 is opened inside the second assembly 3, one end of the connecting column 6 is fixedly connected with a block 7, the block 7 is slidably connected inside the slot 12, a sliding column 8 is slidably connected inside the second assembly 3, the sliding column 8 is slidably connected inside the slot 12, one end of the sliding column 8 is fixedly connected with a snap ring 9, the other end of the sliding column 8 is slidably connected to a limiting block 11, the limiting block 11 is slidably connected inside the slot 12, the limiting block 11 contacts the block 7, the outer wall of the sliding column 8 is provided with a contraction component, the contraction component includes a spring 10, the inner wall of the spring 10 is sleeved on the outer wall of the sliding column 8, one end of the spring 10 is fixedly connected to one end of the snap ring 9, and the other end of the spring 10 is fixedly connected to one side of the limiting block 11.

[0025] Specifically, when the assembly needs to be disassembled, the first step is to insert the fixed column 4 inside the first assembly 2 into the slot 12 inside the second assembly 3. This action not only fixes the position of the two assemblies, but also starts a series of chain reactions. The movement of the fixed column 4 drives the movement of the connecting column 6, and the force on the connecting column 6 drives the sliding of the slider 5, and also causes the movement of the block 7 in the slot 12. In this process, the block 7 contacts the limit block 11, triggering the contraction of the spring 10 of the limit block 11. When the block 7 moves to the other side of the limit block 11, the spring 10 releases its force and returns the limit block 11 to its original position, thereby fixing the position of the block 7. During the disassembly process, the operator needs to continue to push the first assembly 2 into the second assembly 3, which causes the slider 5 connected to the outer wall of the connecting column 6 to apply a squeezing force to the limit block 11. Due to this pressure, the limit block 11 drives the spring 10 to contract, thereby releasing the fixation of the block 7. Then, the operator can easily pull the card block 7 out of the card slot 12, achieving the effect of quick disassembly and assembly.

[0026] Reference Figure 1 and Figure 2 The outer walls of the first assembly 2 and the second assembly 3 are both provided with a sleeve 13, and the inner part of the sleeve 13 is threadedly connected with a threaded rod 14.

[0027] Specifically, after the connection is completed, the connection between the first assembly 2 and the second assembly 3 is further strengthened by inserting the threaded rod 14 into the sleeve 13 of the first assembly 2 and the second assembly 3, thereby achieving a strengthening effect.

[0028] Reference Figure 4 and Figure 5The outer wall of the second assembly 3 is slidably connected with a first protective cover 15, and one side of the first protective cover 15 is rotatably connected with a connecting cover 16. The outer wall of the first assembly 2 is slidably connected with a second protective cover 17, and one side of the connecting cover 16 is rotatably connected to one side of the second protective cover 17. The first protective cover 15 and the second protective cover 17 are connected through the connecting cover 16. The other side of the first protective cover 15 is fixedly connected with a first fixing ring 18, and the inside of the first fixing ring 18 is rotatably connected with a buckle 19. The other side of the second protective cover 17 is fixedly connected with a second fixing ring 20, and the side wall of the second fixing ring 20 is rotatably connected with a connecting plate 21, and one side of the connecting plate 21 is rotatably connected with a handle 22, and one side of the buckle 19 is rotatably connected to the inside of the handle 22.

[0029] Specifically, when using the connecting rod assembly, first, put the first protective cover 15 and the second protective cover 17 on the outer walls of the first assembly 2 and the second assembly 3 to ensure that they are in the correct position. Then, pull the handle 22. This action drives the connection plate 21 to rotate on one side of the second protective cover 17, and also drives the internal buckle 19 to rotate. The rotation of the buckle 19 pulls the first fixing ring 18, so that the first fixing ring 18 drives the first protective cover 15 fixedly connected to the outer wall to move. The movement of the first protective cover 15 also drives the movement of the connecting cover 16. Through the movement of the connecting cover 16, the second protective cover 17 and the first protective cover 15 are tightened and fixed on the outer walls of the first assembly 2 and the second assembly 3, thereby effectively achieving the purpose of protection and achieving the effect of protection.

[0030] Working principle: when the assembly needs to be disassembled, first insert the fixed column 4 fixedly connected inside the first assembly 2 into the slot 12 opened inside the second assembly 3, and the fixed column 4 drives the connecting column 6 fixedly connected at one end to move, and the connecting column 6 is subjected to force to drive the sliding block 5 connected to the outer wall slidingly to move, and at the same time, the connecting column 6 also drives the card block 7 fixedly connected at one end to move inside the card slot 12, and during the movement of the card block 7, it contacts the limit block 11, at this time, the limit block 11 is subjected to force to drive the spring 10 fixedly connected on one side to contract, and when the card block 7 moves to the other side of the limit block 11, the spring 10 unloads the force to rebound and drive the limit block 11 to reset, so that the limit block 11 is stuck on one side of the card block 7 to fix it, and then the threaded rod 14 is inserted into the sleeve 13 set on the outer wall of the second assembly 3 and the first assembly 2 to further fix it, and when disassembling, the first assembly 2 is pushed further into the second assembly 3 to make the outer wall of the connecting column 6 slide The sliding block 5 of the dynamic connection squeezes the limit block 11, and the limit block 11 drives the spring 10 to contract, and then the block 7 is pulled out from the inside of the slot 12, thereby achieving the effect of quick disassembly. When using the connecting rod assembly, first, the first protective cover 15 and the second protective cover 17 are put on the outer wall of the first assembly 2 and the second assembly 3, and then the handle 22 is pulled. The handle 22 is driven by the force to drive the connecting plate 21 with one side rotation connection to rotate on one side of the second protective cover 17, and at the same time, the handle 22 is driven by the force to drive the buckle 19 with the internal rotation connection to rotate, and the buckle 19 is driven by the force to pull the first fixing ring 18 with one side rotation connection to move, and the first fixing ring 18 is driven by the force to drive the first protective cover 15 fixedly connected to the outer wall to move, and the first protective cover 15 is driven by the force to drive the connecting cover 16 with one side rotation connection to move, and the second protective cover 17 and the first protective cover 15 are tightened and fixed to the outer wall of the first assembly 2 and the second assembly 3 through the movement of the connecting cover 16, thereby achieving the protection effect.
