Description

Tweezers convenient to stably clamp U-shaped piece

Technical Field

The utility model relates to tweezers with two elastic arms connected with each other, in particular to tweezers convenient for stably clamping a U-shaped part.

Background

Tweezers are common parts in work and life, are mainly used for clamping objects with small volume, and have a basic structure as shown in figure 1, and comprise two elastic arms 2, wherein first ends of the two elastic arms 2 are connected with each other to form a joint part 1, and anti-skid convex patterns 3 are arranged on the inner side surfaces of the elastic arms 2 close to second ends of the elastic arms 2.

In practical applications, the shapes of objects to be gripped by the tweezers are various, and the conventional tweezers are difficult to stably grip objects with special shapes. For example, in plastic parts injection molded by a mold, there are often processes of embedding metal parts in the plastic parts, and the shapes of the metal parts are different, including "U" shaped parts in the shape of "U".

If the "U" shaped piece 4 is gripped with the above conventional forceps, as shown in fig. 2, the following problems are liable to occur: 1. the position of the U-shaped piece 4 clamped each time is not fixed, and the U-shaped piece is difficult to accurately position; 2. after the clamping is carried out at any angle, the U-shaped part 4 has more freedom of movement, namely, the U-shaped part can move in multiple directions, stable clamping is difficult, the U-shaped part 4 can easily move to a mould during installation, so that position deviation is caused, and the U-shaped part 4 is difficult to install in the mould according to a preset position.

SUMMERY OF THE UTILITY MODEL

The present invention aims to solve the above problems by providing a pair of tweezers which can stably hold a U-shaped member.

The utility model realizes the purpose through the following technical scheme:

the utility model provides a tweezers convenient to stabilize centre gripping "U" form piece, includes two elastic arm, two the first end interconnect of elastic arm forms the joint portion, the position that the inboard surface of elastic arm is close to its second end is equipped with anti-skidding burr, the position that the inboard surface of elastic arm is close to its second end is equipped with the centre gripping recess of bar, the axial of centre gripping recess with correspond the axial of elastic arm is the same, the one end of centre gripping recess is sealed, other end opening and this open end extend to corresponding the second end terminal surface of elastic arm.

Preferably, in order to reduce the effect of stable gripping of the forceps by other non "U" shaped members, the gripping grooves are located in the area of the corresponding non-slip ridges of the resilient arms.

Preferably, in order to minimize the influence on the stable gripping effect of the forceps gripping other non "U" -shaped members, the axial length of the gripping groove is one third to two thirds of the axial length of the corresponding anti-slip ridge of the corresponding elastic arm.

Preferably, in order to minimize the influence on the stable clamping effect of the tweezers clamping other non-U-shaped pieces while ensuring stable clamping of the U-shaped pieces, the axial length of the clamping groove is half of the axial length of the corresponding anti-slip rib on the corresponding elastic arm.

Preferably, the radial section of the clamping groove is semicircular in order to improve the clamping stability of the U-shaped piece.

The utility model has the beneficial effects that:

according to the utility model, the clamping grooves are formed on the inner side surfaces of the elastic arms of the tweezers close to the second ends, so that the two arms of the U-shaped piece can be correspondingly arranged in the two clamping grooves when the U-shaped piece is clamped, the U-shaped piece only has one freedom of movement in the axial movement of the elastic arms, and cannot move radially or rotate, and thus, the functions of stably clamping and accurately positioning the U-shaped piece are realized, and an operator can quickly and accurately complete installation when installing the U-shaped piece.

Detailed Description

The utility model will be further described with reference to the accompanying drawings in which:

as shown in fig. 3 and 4, the tweezers convenient for stably clamping the "U" -shaped piece according to the present invention comprise two elastic arms 2, wherein first ends of the two elastic arms 2 are connected to each other to form a joint portion 1, one end of the joint portion 1 is further provided with a handle (not labeled in the figures, the handle may be omitted), the inner side surface of the elastic arm 2 near the second end thereof is provided with an anti-slip ridge 3, the inner side surface of the elastic arm 2 near the second end thereof is provided with a strip-shaped clamping groove 5, the axial direction of the clamping groove 5 is the same as the axial direction of the corresponding elastic arm 2, one end of the clamping groove 5 is closed, the other end is open, and the open end extends to the end face of the second end of the corresponding elastic arm 2. Preferably, the grip grooves 5 are located in the region of the corresponding non-slip ribs 3 of the elastic arms 2; the axial length of the retaining groove 5 is preferably between one third and two thirds, more preferably half, of the axial length of the corresponding anti-slip ridge 3 in the corresponding resilient arm 2; the radial cross section of the holding groove 5 is preferably semicircular.
