[0002] A universal joint is a fork-shaped structural component that is directly connected to the input shaft or output shaft. The main function of the universal joint is to change the direction of force transmission and allow the angular displacement of the connection part to vary within a certain range. They usually consist of two parts of a cross-shaped structure, which are connected to a cross shaft and supported by bearings. Universal joints can be used alone or in pairs to meet different mechanical needs. In the automotive field, universal joints are particularly important because they help ensure that the vehicle's power transmission system can adapt to the up and down bounces during driving, thereby maintaining driving stability and smoothness.
[0003] The above-mentioned prior art solutions have the following defects: when the existing universal joint fork is in use, some longer transmission shaft parts do not have a good buffer structure, and in the operating state, mechanical stress may cause damage to the equipment or even cause breakage.

When the fixed shaft moves, it can be buffered by the buffer block and the pressure block, and then buffered by the spring, so as to release the mechanical stress in the transmission process and protect the shaft structure.
[0010] Furthermore, the installation groove, movable rod, pressure block, universal joint fork body, fixed shaft and buffer block are symmetrically arranged in two, respectively, the movable rod and the mounting seat are movably connected through a spring, and the pressure block slides inside the cavity.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

An installation groove 2 and a cavity 3 are added to the inside of the shaft of the long rod, and a spring 8 and a pressure block 9 are added inside the cavity 3. The expansion and contraction of the spring 8 can play a role of buffering protection. At the same time, two sets of symmetrical structures are added to make the universal joint fork transmission structure at both ends play a buffering role and effect. A buffer block 13 is added to the outside of the fixed shaft 11. When the fixed shaft 11 moves, it can be buffered by the buffer block 13 and the pressure block 9, and then buffered by the spring 8, so that the mechanical stress in the transmission process is released to protect the shaft structure.
[0023] like Figure 1-4 As shown, the mounting groove 2, the movable rod 7, the pressure block 9, the universal joint fork body 10, the fixed shaft 11 and the buffer block 13 are symmetrically arranged in two, respectively. The movable rod 7 and the mounting seat 5 are movably connected by the spring 8, the pressure block 9 slides inside the cavity 3, the fixed shaft 11 slides inside the mounting groove 2, the buffer block 13 and the pressure block 9 contact each other, the limit block 12 is engaged in the limit groove 4 and is slidably connected to the limit groove 4. The structure of adding the spring 8 buffering inside can achieve the effect of buffering and releasing stress. Through the contact between the buffer block 13 and the pressure block 9, the mechanical stress is offset and released, which is convenient for operation and use.
[0024] The implementation principle of this embodiment is: when the device is in use, the middle connecting shaft 1 starts to transmit, and will be subjected to mechanical stress during the transmission process. At this time, the fixed shaft 11 slides inside the installation groove 2, and the buffer block 13 will contact the pressure block 9. The buffer is achieved through the expansion and contraction of the spring 8 to offset the mechanical stress. When the fixed shaft 11 slides, the limiting effect of the limit groove 4 and the limit block 12 can ensure the stability of the fixed shaft 11 in the internal structure of the connecting shaft 1, thereby ensuring the normal operation of the entire universal joint fork transmission assembly, extending its service life, and avoiding shaft breakage.
