Description

A kind of multi-position sliding pliers

technical field

The utility model relates to the technical field of hardware tools, in particular to a multi-position sliding pliers.

Background technique

Pliers, generally speaking, are a tool for clamping things. Among them, the vise is relatively common, and its structure is as described in the patent CN201520344771.2. It includes a jaw and two handles on the left and right. The jaw and the handle are movably connected by a rotating shaft. The handle includes a first handle and a second handle. The second pliers handle is connected between the first pliers handle and the jaws.

In the actual application process, another usage is to clamp the nut, etc., and then screw the screw and the screw matched with the nut through the sleeve and the wrench on the other side to prevent the nut from slipping during the screwing process. But it requires a lot of clamping force. In practice, people use the principle of leverage to save effort and deform the pliers, that is to say, the pliers head and pliers handle are not designed on the same straight line, but arranged obliquely.

However, there are still some deficiencies, that is, the size of nuts and the like is different, and the size of the pliers head can be opened is limited, so it cannot be widely adapted. The fundamental reason is that the position of the transfer shaft is limited.

Utility model content

The purpose of this utility model is to overcome the defect that the opening size of a pair of pliers jaws in the prior art is limited and cannot be widely adapted, and to provide a multi-position adjustable jaw opening size with a wide range, which can meet Multi-position sliding pliers for nuts of various sizes.

In order to achieve the above purpose, the utility model is achieved through the following technical solutions: a multi-position sliding pliers, including a first pliers handle and a second pliers handle, the front end of the first pliers handle is obliquely provided with a first pliers The front end of the second pliers handle is obliquely provided with a second pliers head, which is characterized in that a chute passing through it in a horizontal direction is arranged in the horizontal direction of the second pliers handle, and the first pliers handle is connected from the chute Pass through the middle and alternate with the second tong handle, a rotating shaft is arranged at the staggered position of the first tong handle and the second tong handle, the rotating shaft is fixed on the first tong handle, and the two sides of the chute A pair of position selection slots are provided on the wall surface for the two ends of the rotating shaft to pass through, and a protrusion is provided on the first pliers handle for the second pliers handle to rely on for position limitation.

The utility model utilizes the design that the rotating shaft of the hinged two pliers handles can be stationary relative to one of them and slide to the other, so that the distance between the two pliers heads can be expanded by multiple positions, thereby meeting the requirements of nuts with multiple sizes and specifications. Among them, the design that the first tong handle passes through the chute of the second tong handle makes the two relatively closely connected and not easy to fall off. Pulling both of them will put too much pressure on the rotating shaft, which is very easy to damage. The position selection groove is for the sliding of the rotating shaft, so that the distance between the two clamp heads can be expanded by multiple positions, and the protrusion is used as a limit function after position adjustment.

Preferably, the pair of parallel wall surfaces of the position selection groove are both wavy, and the concave pairs are arranged in a one-to-one correspondence with the concave convex pairs, and the diameter of the rotating shaft matches the circle formed by each pair of concave pairs in the position selection groove. The cross-section of the rotating shaft is a circle with a notch, and the width of the rotating shaft cut out by the notch is smaller than the distance between each pair of convex and convex in the position selection groove.

The circular notch design of the rotating shaft and the wavy design of the slot wall of the position selection slot are also designed to stabilize the positioning of the two clamp heads after adjustment.

Preferably, a pair of corrugated jaws are provided on the inner sides of the first pincer head and the second pincer head opposite to the engaging jaws.

To prevent the clamped items from slipping, a corrugated tiger mouth is set on the occlusal jaw, that is, anti-skid corrugations are set on the inner wall of the tiger mouth.

Preferably, a soft silicone sleeve is sheathed on the rear ends of the first pliers handle and the second pliers handle.

The soft silicone sleeve enhances the tactile feeling when the human hand touches the pliers handle and reduces the tingling sensation during force application.

Beneficial effects: the utility model utilizes the design that the rotating shaft of the hinged two pliers handles can be stationary relative to one of them and slide to the other, so that the distance between the two pliers heads can be expanded by multiple positions, thereby meeting the requirements for nuts with multiple sizes and specifications.

detailed description

In order to make the technical means, creative features and objectives of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments.

Embodiment: As shown in Fig. 1 and Fig. 2, a kind of multi-position sliding pliers includes a first pliers handle 1 and a second pliers handle 2, and a first pliers head 6 is arranged obliquely on the front end of the first pliers handle 1, The front end of the second pincer handle 2 is obliquely provided with a second pincer head 5, and the second pincer handle 5 is horizontally provided with a chute 3 passing through it transversely, and the first pincer handle 1 passes through the chute 3 and is connected with the first pincer handle 1. The two pliers handles 2 are arranged in a staggered manner. A rotating shaft 4 is arranged at the staggered position of the first pliers handle 1 and the second pliers handle 2. The rotating shaft 4 is fixed on the first pliers handle 1. A pair of supplying rotating shafts are arranged on the two walls of the chute 3. 4 There are position selection slots 7 inserted at both ends, and a protrusion 8 is provided on the first pliers handle 1 for the second pliers handle 2 to rely on to limit its position.

A pair of parallel walls of the position selection groove 7 are all wavy, and the concave to concave convex is arranged in a one-to-one correspondence. The diameter of the rotating shaft 4 matches the circle formed by each pair of concave to concave in the position selecting groove 7. The cross section is a circle with a notch, and the width of the rotating shaft cut out by the notch is smaller than the distance between each pair of convex to convex in the position selection groove 7 .
