Description

Quick-adjusting olecranon pliers

Technical Field

The utility model belongs to the technical field of manual hardware and tools's technique and specifically relates to a quick adjustment olecranon pincers.

Background

When a workpiece is clamped or twisted by the ordinary olecranon pliers, the nut on the screw rod of the pliers body on the olecranon pliers needs to be adjusted manually one by one, the opening amount is adjusted to be slightly larger than the size of the workpiece, then the nut is adjusted again, the opening amount is slowly reduced, and the workpiece is gradually clamped, so that time is wasted, and the operation is troublesome.

Disclosure of Invention

The invention aims to overcome the defects of the technology and provides the quick-adjustment olecranon pliers which are simple to operate, reasonable in design and capable of achieving quick adjustment of the opening amount.

The technical scheme adopted by the invention is as follows: the quick adjusting olecranon pliers comprise a lower plier body, a rivet I, a rivet II and snap springs, and are characterized by further comprising an upper plier body, a button, a sleeve iron, a pin shaft, a worm, a support and a spring, wherein a row of teeth with certain angles are milled on the handle part of the upper plier body, the worm can be meshed with inclined teeth on the handle part of the upper plier body more tightly by a certain angle, the handle part of the upper plier body penetrates through the sleeve iron, the upper part and the lower part of the front end of the support are respectively provided with a through hole, two through holes are respectively arranged on the two sides of the rear end of the support, the pin shaft penetrates through the upper through hole and the lower through hole on the front end of the support to fix the worm on the support, the snap springs are respectively arranged at the two ends of the pin shaft to prevent the pin shaft from falling off, the support penetrates through the sleeve iron, then the button is riveted to the support by the rivet I through the, the worm is meshed with the helical teeth on the handle part of the upper clamp body, a through elongated slot is formed in the middle of the upper clamp body, the lower clamp body penetrates through the elongated slot, and the lower end of the head part of the lower clamp body and the sleeve iron are riveted and sealed together through a rivet II.

the labels in the figure are: the improved pliers comprise an upper pliers body 1, a lower pliers body 2, a button 3, a rivet I4, a rivet II 5, a set of iron 6, a pin shaft 7, a worm 8, a support 9, a clamp spring 10 and a spring 11.

Detailed Description

As shown in fig. 1 to 7, the quick adjusting olecranon pliers comprises a lower plier body 2, a rivet i 4, a rivet ii 5 and a clamp spring 10, and is characterized by further comprising an upper plier body 1, a button 3, a sleeve iron 6, a pin shaft 7, a worm 8, a support 9 and a spring 11, wherein a handle of the upper plier body 1 is milled with a row of teeth with certain angles, the teeth with certain angles can enable the worm 8 to be meshed with inclined teeth of the handle of the upper plier body 1 to be more tightly fixed, the handle of the upper plier body 1 penetrates through the sleeve iron 6, the upper end and the lower end of the front end of the support 9 are respectively provided with a through hole, two through holes are respectively arranged on two sides of the rear end, the pin shaft 7 penetrates through the upper and lower through holes on the front end of the support 9 to fix the worm 8 on the support 9, the clamp spring 10 is respectively arranged at two ends of the pin shaft 7 to prevent the pin shaft 7 from falling off, the support 9 penetrates through the sleeve iron 6, then the rivet, thus, the spring 11 applies outward force to the button 3, the button 3 drives the worm 8 through the support 9, the worm 8 is meshed with the helical teeth of the handle part of the upper clamp body 1, the middle part of the upper clamp body 1 is provided with a through long groove, the lower clamp body 2 penetrates through the long groove, and the lower end of the head part of the lower clamp body 2 and the sleeve iron 6 are riveted together through the rivet II 5.

When a workpiece needs to be clamped or twisted, the button 3 drives the worm 8 by virtue of the elastic force of the spring 11, so that the worm 8 is meshed with the helical teeth of the handle part of the upper clamp body 1, the opening amount can be finely adjusted by rotating the worm 8, when the adjustment is needed, the force close to the lower clamp body 2 is firstly applied to the upper clamp body 1, the boss on the lower clamp body 2 pushes the button 3 in the opposite direction, the whole formed by the button 3 and the bracket 9 drives the worm 8 to separate the worm 8 from the helical teeth of the handle part of the upper clamp body 1, so that the upper clamp body 1 can freely slide up and down and can rapidly reach a proper position, the upper clamp body 1 is loosened, and the worm 8 is re-meshed with the helical teeth of the handle part of the upper clamp body 1 by virtue of.

During adjustment, the button 3 can be directly pressed by hands, the button 3 drives the worm 8 through the support 9 and the pin shaft 7, so that the worm 8 is separated from the oblique teeth on the handle part of the upper pliers body 1, the opening amount of the olecranon pliers can be quickly adjusted, the operation is simple, and much time can be saved.
