Description

Circlip pliers

Technical Field

The utility model relates to an appurtenance among the pincers worker operation process, especially a laborsaving jump ring pincers of operation belong to pincers worker instrument technical field.

Background

The shaft stopper and the hole stopper are commonly called as snap springs, the shaft stopper and the hole stopper are widely used as axial positioning pieces on a machine tool, and the shaft stopper and the hole stopper are usually installed or disassembled by using snap spring clamps in machine tool maintenance. The hole stopper is clamped in a hole groove in a part by taking a disassembling hole stopper as an example, two sharp mouths of the clamp spring pincers head need to extend into two disassembling holes of the hole stopper during disassembling, and the clamp spring pincers are pinched forcibly to take the hole stopper out of the hole. Years of practice prove that the old-fashioned jump ring pincers have a defect that when a hole stopper is taken, a hand must always deform the hole stopper with large force, and the hole stopper is required to be righted to be taken out, so that the operation is time-consuming and labor-consuming, and the hand is easy to shake when being pinched hard, so that the operation is not lasting, the hole stopper is easy to slide out of a sharp mouth of a clamp head of the jump ring pincers, the hole stopper cannot be taken out, and the work efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a jump ring pincers simple structure, with low costs, operation labour saving and time saving.

The utility model discloses a following technical scheme realizes:

a clamp spring clamp comprises two clamp bodies, two spring pieces, a first buckle, a second buckle and a locking screw; the clamp heads of the two clamp bodies are hinged in a crossed manner, the two spring pieces, the first buckle and the second buckle are all arranged on the inner sides of the handles of the two clamp bodies, the lower ends of the two spring pieces are fixedly connected with the handles of the two clamp bodies respectively, and the upper ends of the two spring pieces are fixedly connected with each other; the outer end of the first buckle is fixedly connected with the handle tail of one clamp body, the outer end of the second buckle is slidably sleeved on the handle of the other clamp body, the locking screw is arranged on the outer side of the outer end of the second buckle, when the hole block is taken out, the inner end of the first buckle is hooked with the inner end of the second buckle, and the locking screw abuts against the outer side of the handle tail of the other clamp body.

The object of the invention is further achieved by the following technical measures.

In the circlip pliers, the inner end of the first buckle extends downwards vertically to form the first barb.

In the circlip pliers, the inner end of the second buckle extends upwards to form a second barb.

In the circlip pliers, when the hole stopper is removed, the first barb is hooked on the second barb.

In the snap spring pliers, the upper end of one spring piece is provided with the connecting hole, and the upper end of the other spring piece is inserted into the connecting hole.

The utility model discloses simple structure, it is with low costs, operation labour saving and time saving can take out hole fender or axle fender fast and high-efficiently according to the needs of equipment maintenance, has shortened maintenance duration, has improved work efficiency. Simultaneously according to different maintenance conditions, the buckle of the different specifications of removable configuration, the utility model discloses an adjustable removable buckle realizes the dismouting that different holes kept off or the axle fender, and application scope is very extensive, is particularly useful for dismantling the maintenance operation that the hole kept off a large amount.

The advantages and features of the invention will be illustrated and explained by the following non-restrictive description of preferred embodiments, which are given by way of example only with reference to the accompanying drawings.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1, the present invention includes two pliers bodies 1, two spring pieces 2, a first buckle 3, a second buckle 4 and a locking screw 5. The binding clip 11 cross-hinged of two pincers bodies 1, two spring leaf 2, first buckle 3 and second buckle 4 all set up in the handle 12 inboard of two pincers bodies 1, and two spring leaf 2 lower extremes weld with the handle 12 of two pincers bodies 1 respectively even, and two spring leaf 2 upper ends link firmly each other, and left side spring leaf 2 upper end is equipped with the connecting hole (not drawn in the figure), and right side spring leaf 2 upper end inserts in the connecting hole. The outer end of the first buckle 3 is fixedly connected with the tail part of the handle 12 of the left forceps body 1, the inner end of the first buckle vertically extends downwards to form a first barb 31, the outer end of the second buckle 4 is sleeved on the handle 12 of the right forceps body 1 and can slide up and down along the handle 12 of the right forceps body 1, and the inner end of the second buckle 4 vertically extends upwards to form a second barb 41. The locking screw 5 is arranged on the outer side of the outer end of the second buckle 4, when the hole block is taken out, the first barb 31 is hooked on the second barb 41, and the locking screw 5 abuts against the outer side of the tail part of the handle 12 of the right forceps body 1.

When the hole stopper is taken out, two sharp mouths of the clamp spring caliper head 11 extend into two dismounting holes of the hole stopper respectively, and the clamp spring caliper is pinched forcibly, when the hole stopper is compressed and deformed by the clamp spring caliper to be smaller than the hole diameter, the second buckle 4 slides to correspond to the position of the first buckle 3 along the handle 12 of the right side caliper body 1, the first barb 31 is hooked on the second barb 41, meanwhile, the locking screw 5 is screwed manually, the clamp spring caliper can overcome the elastic deformation force of the hole stopper in a non-manual state, and the purpose of taking the hole stopper out of the inner hole under the condition of not labor is achieved.

In addition to the above embodiments, the present invention can also have other embodiments, and all technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
