It also facilitates routine physical examinations, immunizations, artificial insemination, pregnancy, treatment, dehorning, calving, and other activities for veterinarians or breeders, reducing labor intensity and improving work efficiency.
[0003] In the existing technology, most cow neck yokes adopt a fixed structure. Some cow neck yokes with adjustable structures can only be adjusted by linear movement, resulting in a small adjustment range. In addition, they lack a self-locking structure, requiring workers to manually tighten the bolts to lock them after each adjustment. Utility Model Content

[0020] By adopting the above technical solution, the sliding hole makes it easy for the fixing pin to slide into the locking hole after sliding, making the self-locking of the device more convenient and quick.
[0021] The beneficial effects of this utility model are:
[0022] This invention utilizes a multi-directional adjustment component for the cow neck yoke. When the angle of the fixed cylinder and sliding rod needs adjustment, the sliding blocks on both sides can move, allowing the fixed cylinder and sliding rod to rotate with the rotating block. The fixed cylinder is fixed inside the connecting sleeve, allowing it to rotate at any angle around the rotation axis. After angle adjustment, the length of the fixed cylinder and sliding rod changes. The first spring and the limiting block work together to allow the sliding rod to move with the rotating block. This allows the device to automatically adjust the connection length when adjusting the angle, making adjustment convenient and quick.
[0023] This invention features a self-locking component for the cow neck yoke. During adjustment, the fixed pin needs to be pulled out from inside the sliding block, and the fixed plate and sliding block are operated by pulling the handle, making the device easy to operate. After adjustment, the control of the fixed pin can be released, and the second spring can drive the fixed pin to move and slide into the corresponding locking hole. This allows the sliding block to be locked in the designated position by the cooperation of the fixed pin and the locking hole, resulting in a good self-locking effect. Attached Figure Description
