Spring clip

Abstract

The invention discloses a spring clip, which comprises a first main body comprising a holding part and a clamping part, a second main body comprising a holding part and a clamping part, and a first pivot element and a locking mechanism, wherein the first main body is pivotably connected with the second main body through the first pivot element and the locking mechanism, the locking mechanism is composed of a pair of friction pair components; in the friction pair components, the first friction pair component comprising a first friction pair element is arranged on the first main body, the second friction pair component comprising a second friction pair element is arranged on the second main body; the first friction pair element and the second friction pair element in pairs arranged in the friction pair components mutually rub each other and play a locking role; and the friction pair elements mainly rub in a plane perpendicular to an axis of the first pivot element. The friction pair components are in pairs arranged in the plane perpendicular to the axis of the first pivot element for contact and friction. Because the plane is wider, the abrasion quantity between the friction pair components is little, and requirements of materials made into the friction pair components are lower, the spring clip can be used reliably for a long time.

Description

technical field [0001] The invention relates to the technical field of mechanical tools, in particular to a stepless adjustable spring clip. Background technique [0002] During the use of the spring clamp, the opening of the jaw needs to be adjusted according to the size of the clamped object. When working, it is better to have a fixed opening. For the convenience of fixing the adjusted opening, there are already a large number of spring clips with locking mechanisms in the prior art. [0003] U.S. Patent US6708587B1 discloses a spring clip, the control part is arranged on the outside of the handle of the pliers, which can be operated with the thumb, which simplifies the labor of the hand, but adopts the technical scheme of setting the rack on the handle of the pliers to achieve step-by-step adjustment . [0004] The spring clamp disclosed in US Pat. No. 6,860,179 B2 and US Pat. No. 7,406,897 B2 has a control part arranged on the inner side of the pincer handle, which ca...

Problems solved by technology

Since a part of the L-shaped element protrudes from the main body, another hand is needed for adjustment, which reduces the degree of freedom of the hand and makes it less convenient to use

In addition, the friction surface between the rod and the L-shaped element is basically parallel to the pivot, and there are also the aforementioned problems of excessive wear and long-term use of the reliability of the locking function, and the requirements for materials are relatively high, resulting in increased costs.
