[0021] 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.

[0022] See also Figure 1-6 The utility model provides a technical solution: a saliva collection device, comprising a steel protective sleeve, a connecting rod is slidably installed in the steel protective sleeve, a limiter is fixedly connected to the steel protective sleeve, a mounting groove is provided in the limiter, a limit pin is slidably installed in the mounting groove, a pin hole is provided on the connecting rod, the pin hole and the limit pin cooperate with each other, a sampling cotton ball is fixedly connected to one end of the connecting rod, an extrusion spring is fixedly connected to the bottom of the steel protective sleeve, and an extrusion disc is fixedly connected to the other end of the extrusion spring.

[0023] In this embodiment, the connecting rod is inserted into the steel protective sleeve and the limit pin cooperates with the pin hole to fix the connecting rod in the steel protective sleeve. Then, the connecting rod can be driven to move by controlling the steel protective sleeve, so that the sampling cotton ball can be inserted into the livestock's oral cavity. Since the connecting rod is completely covered in the steel protective sleeve, the steel protective sleeve is made of high-hardness steel as a whole, which can effectively prevent the steel protective sleeve from being deformed after being chewed, thereby protecting the internal steel protective sleeve. After the detection is completed, the limit pin is moved upward to move it out of the pin hole, and the restriction on the connecting rod can be released. At this time, the extrusion spring will push the extrusion disc to move, and the extrusion disc will pop the connecting rod out of the steel protective sleeve. The connecting rod can be taken out of the steel protective sleeve without the operator touching the sampling cotton ball, which is convenient for later replacement of the connecting rod and sampling cotton ball for re-sampling.

[0024] Among them, in order to achieve the purpose of preventing the connecting rod from popping out directly, the present device is implemented by adopting the following technical solutions: a handle is fixedly connected to the rear end of the steel protective sleeve, a limit positioning groove is provided on the inner wall below the steel protective sleeve, a limit convex strip is fixedly connected to the bottom of the connecting rod, the limit convex strip slides in cooperation with the limit positioning groove, V-shaped spring pieces are fixedly connected to the inner walls on both sides of the steel protective sleeve, sliding grooves are provided on the outer walls on both sides of the connecting rod, three triangular protrusions are equidistantly fixed in the sliding grooves, and the triangular protrusions cooperate with the V-shaped spring pieces.

[0025] The operator can control the movement of the device through the handle, and the limit positioning groove and the limit convex strip slide together to limit the position of the connecting rod inside the steel protective sleeve, so that the pin hole can be aligned with the limit pin, and the triangular protrusion and the V-shaped spring piece cooperate with each other. After the connecting rod is pushed out of the steel protective sleeve, in order to prevent the connecting rod from flying out directly, the triangular protrusion is at the end of the connecting rod. When the connecting rod is about to move out of the steel protective sleeve, the triangular protrusion contacts the V-shaped spring piece, and the triangular protrusion will squeeze the V-shaped spring piece to deform it so that the connecting rod can continue to move out. This process will consume the kinetic energy of the connecting rod. A sampling cotton ball and a triangular protrusion are provided. After testing, the V-shaped spring piece will be stuck at the triangular protrusion closest to the end of the connecting rod to prevent the connecting rod from being directly ejected from the steel protective sleeve. At this time, the connecting rod can be manually pulled out of the steel protective sleeve and the sampling cotton ball can be placed into the test tube.

[0026] Among them, in order to achieve the purpose of fixing the connecting rod in the steel protective sleeve, the present device is implemented by adopting the following technical scheme: a limiting groove is opened on the inner wall of the installation groove, a spring pad is fixedly connected to the limiting pin, a limiting block is fixedly connected to the outer wall of the spring pad, the limiting block is slidably matched with the limiting groove, a pulling head is fixedly connected to the upper end of the limiting pin, and a return spring is sleeved on the limiting pin.

[0027] By making a chamfered angle on the lower end of the limit pin, when the connecting rod is inserted into the steel protective sleeve, the limit pin can be directly pushed up, thereby eliminating the need to manually pull the limit pin up. The limit block and the limit groove slide in cooperation to restrict the limit pin to slide up and down, thereby preventing the limit pin from rotating and causing the angle of the bevel to change. The return spring can provide a certain thrust for the spring washer, and the spring washer will drive the limit pin to insert into the pin hole under the thrust, and the pull head can drive the limit pin to move up.

[0028] The working principle and use process of the utility model are as follows: when in use, the device needs to be placed in a suitable position, the connecting rod needs to be inserted into the steel protective sleeve, and the extrusion disc needs to be pushed to compress the extrusion spring. When the limit pin is inserted into the pin hole, the connecting rod can be loosened. At this time, the handle can be held to drive the device to extend into the livestock's oral cavity. After the livestock saliva is absorbed by the sampling cotton ball, the device can be moved out. At this time, the pull head is pulled to drive the limit pin to move out of the pin hole. After the restriction on the connecting rod is released, the connecting rod will be ejected out of the steel protective sleeve through the extrusion disc under the push of the extrusion spring. The V-shaped spring piece and the triangular protrusion cooperate with each other, so that the end of the connecting rod is still in the steel protective sleeve. At this time, it is necessary to manually pull the connecting rod to move out of the steel protective sleeve and place the sampling cotton ball into the test tube.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
