Problems solved by technology

Animals will struggle instinctively when they are in pain, and this may have the following problems: 1. When the perforator is not released in time, it will cause pulling on the ears of the livestock. cause some damages
2. If the animal escapes, the operator will be taken away by the perforator if he does not have a firm grip on the perforator, and he will not be able to install the sign for the next livestock
Although this patent can release the ears of livestock in time, the structure of the whole device is quite complicated and the manufacturing cost is high
Since the control is mainly realized by the catch control device designed between the two handles, it is very easy to cause misoperation during use, thus triggering the bias device at an inappropriate time, so the stability of the work is not high

Embodiment 1

[0028] Such as figure 1 As shown, the animal ear piercer is composed of a body 1, a fixed handle 2, a movable handle 4, a transmission mechanism, a reset mechanism and other parts.

[0029] The fixed handle 2 is arranged on the main body 1, and the main body 1 has a jaw 3 for loading the sign assembly (namely, the male part 19 and the female part 20). The male part 19 and the female part 20 are respectively arranged on both sides of the jaw 3. The movable handle 4 is hinged on the body 1. Such as figure 1 with image 3 As shown, a needle holder 15 is provided in the main body 1, and the piercing needle 5 is erected on the needle holder 15. The label components in the jaws 3 can be pushed together by threading the needle. A transmission mechanism is provided between the piercing needle 5 and the movable handle 4, and a reset mechanism that can automatically return the piercing needle 5 when the movable handle 4 is buckled is connected to the transmission mechanism.

[0030] Such ...

Embodiment 2

[0035] Such as Figure 4 with Figure 5 As shown, the reset mechanism includes an elastic piece 12 fixed on one end of the guide rod 6, and the other end of the elastic piece is provided with a pin 12a, which is inserted into the socket 4b of the movable handle 4 and can drive the guide rod 6 around it and the body The hinge point rotates. The main body 1 is provided with a slope 13 that can push the pin 12a away from the socket 4b when the movable handle 4 is buckled. The guide rod 6 is also connected with a guide rod 6 to rotate in the opposite direction around its hinge point with the main body. The tension spring 11. The rest of the structure is the same as that of Embodiment 1, and will not be repeated here.

[0036] During the rotation of the movable handle 4, the end of the plug 12a contacts the slope 13 and climbs along the slope 13, so that the elastic sheet 12 is deformed, and the plug 12a gradually separates from the socket 4b. When the handle is buckled, the bolt 12...

Embodiment 3

[0039] Such as Image 6 As shown, in this embodiment, the tension spring 11 is connected to the intermediate rod 8. In addition, the entire tension spring 11 is arranged in the body cavity without a hook spring. When the guide rod 6 is disengaged from the movable handle 4, the guide rod 6 does not have the force to continue its rotation, and obviously it cannot drive the middle rod 8 to rotate. At this time, the intermediate rod 8 starts to return due to only the force of the tension spring 11, thereby driving the hinged guide rod 6, guide rod 2, and guide rod 3 to reset. The rest of the structure is the same as that of Embodiment 1, and will not be repeated here.

Abstract

A perforator for the ear of animal in order to fix a label to it is composed of a main body with a fixed handle, a pair of jaws for putting a label module between them, a movable handle pivoted to said main body, a perforating needle, a drive unit consisting of several guide rods and arranged between perforating needle and movable handle, and a restoring unit for perforating needle.

Description

Technical field [0001] The invention relates to the technical field of machinery, in particular to a punch for marking the ears of livestock. Background technique [0002] In order to facilitate the management of livestock breeding, immunization, identification, etc., people need to put markers on the ears of livestock. Usually, a sign is composed of two parts, a male part and a female part, and is fixed on the ears of livestock through a punch. In the currently commonly used perforator, when the handle is buckled, the jaws are still clamped on the ears of livestock during the installation process of the sign. Animals will struggle instinctively when they are in pain. This may have the following problems: 1. When the perforator is not released in time, it will pull the ears of the livestock. Once the force is strong, the ears will be torn, and the livestock will be cause some damages. 2. If the animal escapes, the operator will be taken away by him if he doesn't grasp the perf...
