Description

One-handed pliers

This creation is a one-handed operation with a one-handed operation and a nearly one-piece clamping.

The conventional water pipe clamp (for example, the Republic of China new patent No. 483387) mainly comprises two handle elements, each having a clamp end and a handle end, wherein one handle element has a sliding shaft for sliding in the long groove of the other handle element, and the long groove has A plurality of embedded grooves are provided for the sliding shaft to be relatively engaged, so that the two handle members can be externally clamped.

However, such a design, once the two handles are relatively open, cannot be reset with one hand, it is necessary to shake one of the handle elements, or both hands can be used at the same time. Quite inconvenient.

The adjacent inlays are quite spaced and the size of the clamp can be limited.

This creation is a one-handed operation with a one-handed operation and a nearly one-piece clamping.

In order to achieve the foregoing object, the present invention provides a one-handed pliers comprising: a pair of pliers handles having a pair of working ends, a pair of gripping ends and a shaft portion for the shaft portion Transforming the working end between relative closure and relative opening; and interlocking the pair The pair of gripping handles are changed between the relative closing and the opposite opening; the pair of gripping handles comprise: a fixed handle having a pair of positioning slots disposed on the fixed handle in parallel with each other; each positioning slot system Having a plurality of positioning backlashes; a slideway is located between the pair of positioning slots; the pair of positioning slots are deflected from the holding end toward the working end; a movable handle, the a shaft portion of the caliper handle is disposed on the movable handle to restrict the movable handle from moving relative to the fixed handle only in the slide rail; the movable handle has a pair of positioning teeth, corresponding to the positioning of the tooth gap, And an average distribution in the circumferential direction of the shaft portion; an elastic portion is coupled to the slide at a position adjacent to the working end portion, and is pivotally connected to the shaft portion at a position of the shaft portion And being rotatable relative to the shaft portion; thereby, when the pair of working end portions are relatively open, for accommodating a clip member therebetween, the one-hand gripping the pair of grip end portions is changed from relative opening to relative Closing, the changing process is to reverse the top of the movable handle between the pair of working ends, The shaft portion is pulled along the slide rail and rotates relative to the elastic portion. When the pair of gripping ends are relatively closed, the pair of positioning teeth are engaged with the pair of positioning gaps of the pair of positioning slots. Positioning, the movable handle is moved from an original position to a clamping position, the pair of working ends can clamp the clip; when the pair of holding ends are relaxed by one hand, the elastic portion pulls the shaft portion, The pair of gripping ends are returned from the clamping position to the original position by retracting the positioning teeth from the positioning backlash of the pair of original mating snap-in positions.

Referring to the first, second, third and fourth figures, the present invention is a one-handed pliers comprising: a pair of pliers handles 10 having a pair of working end portions 10A and a pair of holding ends a portion 10B and a shaft portion 10C for changing between the opposite closing and the opposite opening of the pair of working end portions 10A; and interlocking the pair of holding end portions 10B between the relative closing and the opposite opening; the pair of jaws The handle 10 includes: a fixed handle 11 having a pair of positioning slots 11A disposed on the fixed handle 11 in parallel with each other; each positioning slot 11A has a plurality of positioning backlashes; a slide 11B Between the pair of positioning slots 11A; a movable handle 12, the shaft portion 10C of the pair of caliper handles 10 is located on the movable handle 12 for limiting the movable handle 12 only in the slide 11B, Moving relative to the fixed shank 11; the movable shank 12 has a pair of positioning teeth 12A corresponding to the positioning spurs 11A, and evenly distributed in the circumferential direction of the shaft portion 10C; The pair of positioning slots 11A are substantially deflected from the holding end 10B toward the working end 10A; an elastic portion 20 is connected to the slide 11B at one end and adjacent to the working. The position of the end portion 10A is pivotally connected to the shaft portion 10C at a position of the shaft portion 10C and is rotatable relative to the shaft portion 10C; thereby, when the pair of working end portions 10A are opposite ones Opened to accommodate a clip member 90 (see FIG. 5), and the pair of grip end portions 10B are changed from the relative opening to the relative closing with one hand, and the clip member 90 is at the pair of working ends during the changing process. The movable shank 12 is reversely supported between the portions 10A, and the shaft portion 10C is pulled along the slide 11B (refer to the sixth figure) and rotates relative to the elastic portion 20 when the pair of holding ends 10B are opposite Closing, the pair of positioning teeth 12A are snapped into a positioning gap of one of the pair of positioning slots 11A, and the movable handle 12 is moved from a home position PA to a clamping position PB (see the seventh FIG. 4, the pair of working end portions 10A can clamp the clip member 90; when the pair of gripping end portions 10C are loosened by one hand, the elastic portion 20 pulls the shaft portion 10C The pair of positioning teeth 12A are retracted from the positioning backlash of the pair of original mating positioning positions, and the pair of holding end portions 10B are returned from the clamping position PB to the original position PA (reverse action, the drawing is not shown, Chen Ming).

In fact, the fixing handle 11 is provided with a positioning member 11C for hooking and fixing one end of the elastic portion 20.

The shaft portion 10C includes a locking member 101 and a locking hole 102; the locking hole 102 is located on the movable handle 12; the elastic portion 20 includes: A spring 21 has one end hooked and fixed to the positioning member 11C. A ring member 22 is coupled to the other end of the spring 21 and is looped on the locking member 101 for the elastic portion 20 to be pulled by the shaft portion 10C. And the elastic portion 20 is relatively rotated with the shaft portion 10C.

The use of this creation is as follows:

First, the pair of working end portions 10A are controlled to be relatively open (the pair of holding ends 10B can be pushed away by one hand), and then a clip 90 is placed between the pair of working end portions 10A (see the fifth Figure), again, the one hand begins to grasp the pair of holding ends 10B, so that the pair of holding ends 10B start to gradually change from the relative opening transition to the relative closing, and the clamping member 90 works in the pair. The movable shank 12 is reversely supported between the end portions 10A, so that the shaft portion 10C is pulled along the slide rail 11B (refer to the sixth figure) and rotates relative to the elastic portion 20 when the pair of gripping end portions 10B The pair of positioning teeth 12A are engaged with each other in the positioning gaps of the pair of positioning slots 12A for positioning, and the movable handle 12 is moved from the original position PA (as shown in FIG. 5). To the clamping position PB (refer to the seventh figure), the pair of working end portions 10A can clamp the clip member 90; when the pair of gripping end portions 10C are loosened by one hand, the elastic portion 20 pulls the shaft portion 10C, The positioning tooth 12A is retracted from the positioning tooth gap corresponding to the corresponding positioning position, and the pair of holding end portions 10B are returned from the clamping position PB to the original position PA (reverse action, Surface, not shown, bonded to Chen).

The advantages of this creation are as follows:

[1] It can be operated with one hand. The invention is provided with an elastic portion between the fixed handle and the movable handle. When the clip is clamped between the two working ends, as long as the two gripping ends are gripped, the clip can be opposite to the movable handle. Open (synchronously pull the elastic part), the positioning tooth of the last movable handle is snapped in Positioning backlash positioning of the fixed handle. The clip can be clamped. When the two gripping ends are released, the elastic portion pulls the movable handle to cause the rotation to be reset. It is quite convenient to operate with one hand without any help.

[2] Nearly no segmented clamping has a wide range of applications. The positioning tooth groove of the present invention has a plurality of positioning backlashes, and the gap is extremely small, so that the positioning tooth groove has almost the advantage of clamping the clip without the segment, and the application range is wide.
