DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ear tag mounting device to be mounted on an ear shell of an animal such as a domestic animal.

[0002]

2. Description of the Related Art Conventionally, various types of ear tag wearing devices have been devised in which a pin member is pierced into the ear shell of an animal such as a domestic animal, and an ear tag for identifying an individual animal is engaged. For example, when the lever is grasped with a hand, such as pliers or a yacht, the holding portion of the pin member penetrating the ear shell of the animal and the holding portion of the ear tag approach each other (the point of action is a circular motion). Instead of the mounting device, the holding portion of the marking member is provided in a fixed state at a predetermined interval from the holding portion of the pin member, and the holding portion of the pin member is provided on the holding portion of the marking member. A pistol-type mounting device that can be held and held by one hand that moves linearly toward the user is widely used because of its functional advantage.

In this mounting device, a plunger for pushing a pin member is operated by pushing a lever having a shaft serving as a fulcrum at a specific position provided on a main body, and the plunger is held at the tip of the plunger. The marked member and the pin member are engaged with each other. In addition, many wearers include an automatic return device for the plunger, which operates while the plunger compresses the coil spring when the lever is pushed, and when the ear tag is completely mounted, the compressed coil is returned. The plunger automatically returns to the home position by the spring force of the spring.

In order to shorten the plunger return time, the coil spring requires a considerably strong compression force. For this reason, by increasing the lever stroke,
Attempts have been made to reduce the force required to compress the coil spring and reduce fatigue on the hands, but the disadvantage is that it is difficult to apply force when pushing the lever because the lever stroke is long. However, as a result, it has not been possible to reduce fatigue on hands.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has an ear tag mounting device capable of reducing the stroke distance of a lever without increasing the pushing force of the lever and reducing fatigue on a hand. The purpose is to provide.

[0006]

SUMMARY OF THE INVENTION The gist of the present invention is an ear tag mounting device for inserting an ear tag for identifying an animal into an ear shell of an animal by inserting a pin member into the ear tag. The vessel has a plunger that supports one end of the main body, sets the pin member at the distal end, and pushes the plunger, and an appropriate distance from the distal end of the pin member connected to the main body and set at the end. And a lever for rotating the plunger with a rotating shaft pivotally supported in a shaft hole of the main body, the shaft hole of the main body having a long window parallel to the plunger. A sliding support point is formed on the lever, and a guide wall is formed on the gripping portion side of the main body with which the sliding support point comes into contact when the lever is pulled to some extent. The fulcrum moves upward along the wall, A ear tag mounted device which is characterized in that the axis of rotation of the lever about the dynamic fulcrum moves the shaft hole in the pushing direction of the plunger.

The ear tag wearing device of the present invention will be described in more detail. The ear tag used is an IC chip on which an identification number is marked for identifying an animal such as a livestock, or an animal data is stored. Are provided, and individual identification or individual information is obtained by the ear tag. The ear tag is attached to the animal's ear shell by a pin member that penetrates the animal's ear shell. In addition, the pin member has a structure in which the tip is detached so as not to damage other animals at the sharp tip. It is preferable that a container for accommodating the detached distal end can be attached to the ear tag wearing device.
However, the present invention is not limited to these, and any device may be used as long as it can be mounted on an animal using a mounting device.

A wearer for mounting the ear tag on the ear shell of an animal is provided with a plunger for supporting one end of the body, setting the pin member at the tip and pushing the pin member, and being connected to the body. An ear tag holding portion for holding the ear tag at an appropriate distance from the tip of the pin member set at the end, and a lever for operating the plunger with a rotating shaft supported by a shaft hole of the main body. Consists of The main body is a portion serving as a base of each portion of the mounting device, and in some cases, may be a case.

A part of the plunger is supported by the main body, and a pin member can be attached to a tip of the plunger. When the operation of the plunger is completed, the pin member is attached to an ear tag held at the tip of the plunger. It is something that can be pierced. It is desirable that the plunger has an automatic return device, and the plunger operates while compressing the coil spring when the lever is pushed, and when the ear tag is completely mounted, the plunger automatically receives the elastic force of the compressed coil spring. So that the plunger returns to the home position.

The plunger can be moved forward and backward by directly or indirectly connecting the operating point of the lever to the lever. A pulley is provided at the rear end of the plunger, and a string such as a chain is formed in a U-shape. One end may be pulled by a lever. That is, in order to efficiently transmit the force to the plunger, it is desirable that the cord is suspended between the main body and the lever action point via the rear end of the plunger. It is desirable to use a steel chain or wire for this string-like body because strength is desired, but any string may be used as long as there is no problem in strength. A guide pin may be provided in parallel with the plunger, a slide connected to the chain may be inserted through the guide pin, and the link plate may be connected to the slide and the action point of the lever by a connection pin.

On the other hand, the main body material is formed of a synthetic fat material or a metal material, and the plunger is also formed of a resin material or a metal material in a rod shape. Further, the lever is also made of a resin material or a metal material, but it is preferable to use a member made of a material that is hardly worn on the portion of the rotation shaft and the sliding fulcrum.
The rear of the main body is a handle portion, on which a guide wall composed of a substantially vertical wall is formed. This wall may be formed with the molding of the body, or a separate member may be attached to the body to form a vertical wall. The lever is supported on a shaft hole of the main body via a rotation shaft, and the shaft hole is an elongated hole that is horizontal, that is, parallel to the plunger. Here, “parallel” means substantially parallel.

[0012] The lever further has a sliding fulcrum that can slide rearward. The sliding fulcrum contacts the guide wall formed at the rear of the main body after the lever has retreated to some extent, and the lever further retreats. The upper part of the lever moves in the direction of travel of the plunger with the ascending sliding fulcrum as the fulcrum,
At that time, the rotation shaft moves in the same direction as the plunger in the shaft hole parallel to the plunger. The part that becomes the sliding fulcrum is also formed together with the molding of the lever,
A separate member may be attached to the main body to serve as a sliding fulcrum. Further, a member such as a bearing may be provided at a portion serving as a sliding fulcrum, so that the sliding operation becomes a smoother operation.

[0013] The method of holding the pin member of the plunger and the method of holding the marker member may be achieved by using a suitable method. May be appropriately selected so as not to affect the mounting operation.

[0014]

Since the ear tag mounting device of the present invention is configured as described above, a pin member is provided at the tip of the plunger which has returned to the home position, and the ear tag holding portion opposed to the plunger is provided. When the ear tag is set, the ear shell of an animal such as a livestock is positioned between the pin member and the ear tag, and the lever is gripped (pushed), the lever pivots about the rotation axis, and accordingly, The sliding fulcrum provided on the lever comes into contact with the guide wall of the main body and then moves substantially vertically upward while being guided and slid. In addition, the rotating shaft of the lever moves in the direction substantially opposite to the guide in a horizontally long shaft hole formed in the main body in a substantially horizontal direction in accordance with the upward movement of the sliding fulcrum.

That is, since the sliding fulcrum provided on the lever comes into contact with the guide wall by the rotation of the lever and pushes the lever in the direction opposite to the guide wall, the plunger is pivotally supported by the operating point of the lever. Can be moved longer by the distance the lever is pushed out. From this relationship, it is possible to shorten the gripping (pushing) stroke of the lever without changing the movement distance of the plunger.

[0019]

As described above, the ear tag mounting device of the present invention has a structure in which the sliding fulcrum provided on the lever comes into contact with the guide wall and pushes the lever in the direction opposite to the guide wall by turning the lever. Therefore, the stroke of the lever grip (push) can be shortened without increasing the pushing force of the lever without changing the moving distance of the plunger. For this reason, even when the wearing operation using the ear tag wearing device is performed for a long time, the gripping force of the lever is easily applied, so that the fatigue on the hand can be reduced.

Further, since the point of action of the lever pivotally supported by the plunger moves parallel to the plunger, the force can be efficiently transmitted to the plunger.
