Description

Opening and closing spring clamp

The present invention relates to a hand tool, and more particularly to a spring-loaded dual-purpose forceps.

The commonly used spring pliers are usually used to remove the C-ring. In order to disassemble different types of C-rings such as the inner shaft or the outer shaft, the common spring pliers are of two types, one is a normally closed type, when the spring clamp When the handle is opened, the front end clamp is closed, and when the handle is pressed, the clamped object can be extended outward for disassembling the outer shaft type C-ring, and the other is the normally open type, the spring clamp When the handle is opened, the front end clamp is also opened. When the handle is pressed, the clamp can be brought inwardly close to the clamped object, and can be used for disassembling the inner shaft type C-ring, generally two different types of spring clamps. They are used separately. Therefore, if it is often necessary to alternately disassemble different types of C-rings, it is necessary to prepare multiple tools to respond, which is quite troublesome and extremely inconvenient, and is necessary for improvement.

In order to solve the problem that the existing spring clamp can only be used for a single use, it is necessary to prepare a plurality of tools for alternate use, which is a troublesome problem. The main purpose of the present invention is to provide a spring-loaded dual-purpose clamp which is attached to the handle. The adjustment piece is provided, and the user can change the operation mode of the handle by pulling the adjustment piece, and simultaneously compound the normally closed type and the normally open type spring clamp. In one, it can be switched quickly and only needs one preparation, which is quite convenient and practical.

The technical means used in the present invention is to provide a spring-loaded dual-purpose clamp, comprising two handles, two clamps and two adjustment pieces, wherein: the two handles are left and right symmetrical, and the two The handles are disposed in the front and rear directions, and the two handles respectively have a hand grip under the bottom, and an adjusting portion is respectively formed above the hand grips, and the two adjusting portions are arranged at the front and rear intervals and form a clip. a sliding hole is formed in each adjusting portion, and two sliding holes respectively are formed on the left and right sides of the pivoting hole; the two clamping pieces are sandwiched between the clamping spaces of the two handles, and the two clamping jaws The two pivoting members are disposed on the two grips, and the two clamping jaws are symmetrical in shape and left and right. The two clamping jaws form a letting angle on the inner lower edge, and the two clamping jaws are An actuating rod is respectively protruded from the lower side of the piece, and the two actuating rods are respectively protruded from the front and rear sides of the two clamping pieces, and the two operating rods are respectively disposed on the two sliding holes; the two adjustments are respectively The film system is respectively pivotally disposed on the adjustment portions of the two handles, in the top surface of the two adjustment pieces Forming a recessed retaining groove, and respectively forming a groove corresponding to one of the two actuating rods on the left and right sides of the retaining groove, wherein the two adjusting pieces are correspondingly engaged in one of the clamping grooves A working rod.

The opening and closing spring clamp, wherein the opposite inner side faces of the two grips are respectively recessed to form a snap ring groove coaxial with the pivot hole, and the two clamp pieces are respectively convexly disposed on the front front and rear sides. Adjacent to the semicircular ring edge, the two clamp pieces are respectively corresponding to the front and rear of the two ring edges Place the ring groove on the handle.

In the above-mentioned opening and closing spring clamp, the two clamp pieces are respectively provided with a through hole at the lower side, and the actuating rods are detachably inserted into the through holes of the two clamp pieces respectively.

In the above-mentioned opening and closing spring clamp, the two adjustment pieces are respectively provided with a dial portion which is formed in a disk shape on the same side and which has irregularities on the outer circumference.

The above-mentioned opening and closing spring clamp, wherein the two grips are provided with a spring between the two grips.

The improved function obtained by the present invention is that the front end of the handle is combined with a clamp piece, and the different clamp pieces can be fixed through the adjustment piece disposed on the handle, so that the handle can be switched and coupled to different clamp pieces, so that The user can adjust the adjustment handle to a normally closed or normally open type according to requirements, so that the use of two different tools can be achieved with only a single tool, which can save purchase and convenient use, Convenient.
