Description
Technical Field
The present invention relates to tweezers, and more particularly, to tweezers for holding electronic components.
Background
in the modern society, the characteristic that the clamping part of the tweezers is small is often utilized to clamp objects which can not be stably taken by general people; the tweezers in the prior art particularly comprise two clamping arms, the top ends of the two clamping arms are connected, and when the tweezers are used, a user presses the two clamping arms to enable the bottom ends of the two clamping arms to approach each other so as to clamp an object.
However, the prior art tweezers have a disadvantage that when the shape and surface of the object to be clamped are smooth, the object to be clamped is often dropped off due to the unstable holding or the deviation of the clamping points because the user has only two contact points (the bottom ends of the two clamping arms) during the process of clamping the object.
Particularly, when the electronic component manufacturing process is to use tweezers to pick up tiny electronic components, for example, when the electronic component manufacturing process is applied to a Radio Frequency (RF) manufacturing process, the electronic component manufacturing process is matched with soldering iron or a hot air gun for soldering, or when the electronic component manufacturing process is applied to surface-mount device (SMD), the electronic component manufacturing process is matched with the SMD by picking up the SMD; therefore, in the manufacturing process of electronic components, not only an object with a very small volume needs to be clamped, but also various operations need to be carried out on the object, or even the clamped object needs to be pressed on a circuit board or the like with slight force, so that the components are easily carelessly thrown out or blown away by a heat gun under the condition of unstable holding by force.
therefore, the tweezers in the prior art need to be improved.
Disclosure of Invention
In view of the above-mentioned drawbacks and deficiencies of the prior art, the present invention provides a four-claw forceps, which is less likely to fall off when a user grasps an object.
In order to achieve the above-mentioned object, the present invention provides a four-jaw tweezers, which comprises two main clamping arms, two connecting rods, two auxiliary clamping arms, and two extension springs. The two opposite ends of each main clamping arm are respectively a combination end and a main clamping end, and the combination ends of the two main clamping arms are connected. Each main clamping arm is provided with a connecting part which is positioned between the combination end and the main clamping end and is adjacent to the combination end. The two connecting rods are respectively pivoted on the two main clamping arms. The two opposite ends of each connecting rod are respectively a first end and a second end, and the first end of each connecting rod is pivoted on the corresponding main clamping arm. The two auxiliary clamping arms are positioned between the two main clamping arms and are pivoted with each other. The opposite ends of each auxiliary clamping arm are respectively a pivoted end and an auxiliary clamping end, and the pivoted end of each auxiliary clamping arm is pivoted at the second end of the corresponding connecting rod. When the two main clamping arms are clamped by an external force, the path for driving the two auxiliary clamping arms to be clamped is vertical to the path for clamping the two main clamping arms. The two extension springs are respectively connected with the two main clamping arms and the two auxiliary clamping arms. One end of each extension spring is connected to the connecting part of one main clamping arm, and the other end of each extension spring is connected to the pivoting end of the auxiliary clamping arm pivoted with the other main clamping arm.
The invention has the advantages that under the normal state, the two main clamping arms can maintain a certain opening angle, and the opening angle can slightly pull the extension springs connected with the main clamping arm and the auxiliary clamping arm at different sides; when the object is to be clamped, a user only needs to press the two main clamping arms, and at the moment, because the distances between the main clamping arms and the auxiliary clamping arms at different sides are shortened, the extension spring can restore the original length to pull the auxiliary clamping arms upwards, so that the two auxiliary clamping arms can automatically pivot to enable the auxiliary clamping ends of the two auxiliary clamping arms to be closed oppositely, and therefore the main clamping ends of the two main clamping arms and the auxiliary clamping ends of the two auxiliary clamping arms can be closed from the center from four directions to clamp the object, and the object can be clamped by the four clamping arms to achieve the effect of stably clamping the object so as to prevent the object from falling off easily; the invention can be operated just like a common tweezers, and the invention can achieve the aim of stably clamping an object through the four clamping arms.
Further, each of the main clamping arms is a long flat plate and the width of each of the main clamping arms is gradually reduced from the combining end to the main clamping end.
Further, each of the sub-clip arms is a long flat plate, the width of each sub-clip arm is gradually reduced from the pivot end to the sub-clip end, and the two sub-clip ends of the two sub-clip arms are bent and extended toward each other.
Furthermore, the four-jaw tweezers further comprise four protective sleeves respectively sleeved on the main clamping ends of the two main clamping arms and the auxiliary clamping ends of the two auxiliary clamping arms.
Further, the two main clamping arms and the two auxiliary clamping arms are made of metal, and the protection sleeves are made of plastic.

Detailed Description
The technical means adopted by the invention to achieve the preset object are further described below by combining the drawings and the preferred embodiments of the invention.
Referring to fig. 1 and 2, the four-jaw tweezers of the present invention comprise two main clamping arms 10, two connecting rods 20, two sub-clamping arms 30, and two extension springs 40.
Referring to fig. 2, 3 and 5, the two opposite ends of each main clamping arm 10 are respectively a combining end 11 and a main clamping end 12, the combining ends 11 of the two main clamping arms 10 are connected, and the distance between the two main clamping arms 10 increases from the combining end 11 to the main clamping end 12. Each main clamping arm 10 is provided with a connecting portion 13, and the connecting portion 13 is located between the combining end 11 and the main clamping end 12 and is adjacent to the combining end 11. Specifically, the combining end 11 of each main clamping arm 10 is a plane, that is, the two main clamping arms 10 are combined in a plane manner (as shown in fig. 5). The connecting portion 13 is not located on the plane of the coupling end 11, but adjacent to the plane, in other words, the connecting portion 13 is located at a distance from the two main clamping arms 10, but not at a location where the two main clamping arms 10 are connected to each other.
In the present embodiment, each main clamping arm 10 is a long flat plate and has a width gradually decreasing from the coupling end 11 to the main clamping end 12 (as shown in fig. 3), so as to facilitate clamping the object. And the main clamping arm 10 is made of metal. However, the shape and material of the main clamp arm 10 are not limited to the above, for example, the main clamp arm 10 may also be made of plastic.
The two connecting rods 20 are respectively pivoted to the two main clamping arms 10. The two opposite ends of each link 20 are respectively a first end 21 and a second end 22, and each link 20 is pivotally mounted to the corresponding main clamp arm 10 by the first end 21.
The two auxiliary clamping arms 30 are located between the two main clamping arms 10, and the two auxiliary clamping arms 30 are pivoted to each other. The opposite two ends of each sub-clip arm 30 are respectively a pivoted end 31 and a sub-clip end 32, each sub-clip arm 30 is pivoted at the second end 22 of the corresponding connecting rod 20 by the pivoted end 31, and when the two main clip arms 10 are clipped by an external force, the path for driving the two sub-clip arms 30 to clip is vertical to the path for clipping the two main clip arms 10, specifically, the two sub-clip arms 30 are pivoted at the middle sections thereof; when the two main clamping arms 10 are clamped by external force, the path of the two sub-clamping arms 30 is perpendicular to the path of the two main clamping arms 10.
In the present embodiment, each of the sub-clip arms 30 is a long flat plate, and the width of the sub-clip arm is gradually reduced from the pivot end 31 to the sub-clip end 32, and the two sub-clip ends 32 of the two sub-clip arms 30 are bent and extended towards each other, so as to reduce the distance between the two sub-clip ends 32 of the two sub-clip arms 30, and further achieve the effect of clipping objects by the two sub-clip arms 30 with a small pivot angle. In addition, the two secondary arms 30 are made of metal. However, the shape and material of the sub-clip arm 30 are not limited to the above, and for example, the sub-clip arm 30 may be made of plastic.
The two extension springs 40 are respectively connected to the two main clamping arms 10, and the two extension springs 40 are respectively connected to the two sub-clamping arms 30. One end of each tension spring 40 is connected to the connecting portion 13 of one of the main clamp arms 10, and the other end of each tension spring 40 is connected to the pivot end 31 of the sub-clamp arm 30 pivotally connected to the other main clamp arm 10. In other words, it is assumed that the two main clamp arms 10 are a first main clamp arm 10A and a second main clamp arm 10B, and the two sub-clamp arms 30 are a first sub-clamp arm 30A and a second sub-clamp arm 30B. The first main clamping arm 10A is connected to the first auxiliary clamping arm 30A through one of the connecting rods 20, and the second main clamping arm 10B is connected to the second auxiliary clamping arm 30B through the other connecting rod 20. Two ends of one of the extension springs 40 are respectively connected to the connecting portion 13 of the first main clamping arm 10A and the pivoting end 31 of the second sub-clamping arm 30B, and two ends of the other extension spring 40 are respectively connected to the connecting portion 13 of the second main clamping arm 10B and the pivoting end 31 of the first sub-clamping arm 30A. Each extension spring 40 pulls the main clip arm 10 and the sub clip arm 30 connected thereto toward each other.
Referring to fig. 2, in the present embodiment, each extension spring 40 connects the main clamping arm 10 and the sub-clamping arm 30 in such a manner that a through hole is respectively formed on the connecting portion 13 of the main clamping arm 10 and the pivot end 31 of the sub-clamping arm 30, and two ends of the extension spring 40 are hooked in the two through holes. But not limited to this, they may be connected by other means.
Referring to fig. 3 and 5, in the present invention, under normal conditions, the two main clamping arms 10 maintain a certain opening angle, and the opening angle slightly pulls apart the tension springs 40 connected to the main clamping arm 10 and the sub-clamping arm 30 (the first main clamping arm 10A and the second sub-clamping arm 30B, or the second main clamping arm 10B and the first sub-clamping arm 30A) on different sides. In other words, the elasticity of the two main clamping arms 10 for opening is larger than that of the two extension springs 40.
Referring to fig. 4, when a user wants to pick up an object, he only needs to press the two main clamping arms 10. At this time, since the distance between the two main clamp arms 10 is shortened, the distance between the sub-clamp arms 30 located inside the main clamp arms 10 is also shortened, and the distances between the main clamp arms 10 and the sub-clamp arms 30 on different sides are shortened, so that the extension spring 40, which is originally pulled apart, returns to its original length and pulls the sub-clamp arms 30 upward. The two secondary arms 30 and the connecting rod 20 are automatically pivoted to move the secondary clamping ends 32 of the two secondary arms 30 toward each other, so that the primary clamping ends 12 of the two primary arms 10 and the secondary clamping ends 32 of the two secondary arms 30 move toward each other from four directions to clamp an object. The object can be clamped by the four clamping arms 10 and 30 to achieve the effect of stable clamping so as to prevent the object from falling off easily. The invention can achieve the purpose of stably clamping an object through the four clamping arms 10 and 30 only by operating and pressing the two main clamping arms 10 like a common tweezers.
In addition, in other embodiments, the present invention further comprises four protective sleeves, which are respectively disposed on the main clamping ends 12 of the two main clamping arms 10 and the auxiliary clamping ends 32 of the two auxiliary clamping arms 30. In the embodiment, the protective sleeves are made of plastic, so that even though the main clamping arm 10 and the sub-clamping arm 30 are made of metal, electronic components with insulation requirements can be clamped through the plastic protective sleeves (for example, for radio frequency fine tuning). But not limited to this, the protective sheath can be changed into other materials according to the requirement.
Although the present invention has been described with reference to the above embodiments, it should be understood that the present invention is not limited to the above embodiments, but rather, may be embodied in many different forms and modifications without departing from the spirit and scope of the present invention.
