Abstract

The invention discloses a pulling pliers, relates to a pulling device capable of removing an installed expansion bolt, and belongs to the field of hardware tools. Including binding clip, pincers handle, connecting portion, connect through connecting portion between binding clip and the pincers handle, step up through the expand tube mouth portion to expansion bolts, then utilize lever structure to draw for the expand tube is carried to draw and is pulled out, and then pulls out expansion bolts.

Description

Pulling-out forceps

Technical Field

The invention discloses a pulling pliers, relates to a pulling device capable of removing an installed expansion bolt, and belongs to the field of hardware tools.

Background

Expansion bolts are installed at all positions, and wall, ground etc. carry out fixed mounting, utilize the expand tube expansion to increase the sectional area, and the pipe wall forms the friction and fastens, dismantles the difficulty, and the expand tube imbeds completely downtheholely, and current instrument can not carry out the clamping to the expand tube, forms to draw, and whole dismantlement is inefficient.

Disclosure of Invention

In order to improve the situation, the invention provides a pair of pulling pliers which can form a jaw structure of an oblique displacement clamping clip, clamp an expansion pipe and pull out the expansion pipe by matching with a lever structure.

The pulling-out forceps of the invention are realized as follows: the invention relates to a pulling-out forceps, which comprises a forceps head, a forceps handle and a connecting part, wherein the forceps head and the forceps handle are connected through the connecting part, the connecting part is of a V-shaped structure, the bottom of the connecting part is an arc surface, a nut open slot is formed in the inner side of the connecting part, the forceps head is obliquely arranged, the tail end of the forceps handle is raised, an adjusting nut is arranged on the forceps head, an adjusting block is arranged on the lower edge of the forceps head in a sliding manner, the adjusting block is meshed with the adjusting nut, a fixed clamp is arranged on the forceps head, the lowest point of a fixed clamp is lower than the lowest point of the connecting part;

clamping teeth are arranged on the inner sides of the fixed clamp and the movable clamp, and the inner side surface of the movable clamp is an arc surface;

the nut open slot is a multi-specification open slot.

Has the beneficial effects.

Firstly, can form the clamping to the expand tube, avoid forming the interference with the drill way.

And secondly, pressing down and drawing, and adopting a lever principle to quickly pull out.

Thirdly, the structure is simple, convenient and practical.

Drawings

FIG. 1 is a perspective view of a pulling forceps according to the present invention;

fig. 2 is a schematic structural view of a pulling forceps of the present invention.

In the attached drawings

Wherein the method comprises the following steps: the clamp comprises a fixed shaft (1), a clamp head (2), an adjusting nut (3), a clamp handle (4), a nut open slot (5), a connecting part (6), an adjusting block (7), a movable clamp (8), a clamping tooth (9) and a fixed clamp (10).

The specific implementation mode is as follows:

the pulling-out forceps of the invention are realized as follows: the invention relates to a pulling-out forceps, which comprises a forceps head (2), a forceps handle (4) and a connecting part (6), wherein the forceps head (2) is connected with the forceps handle (4) through the connecting part (6), the connecting part (6) is of a V-shaped structure, the bottom of the connecting part is an arc surface, a nut open slot (5) is formed in the inner side of the connecting part, the forceps head (2) is obliquely arranged, the tail end of the forceps handle (4) is lifted, an adjusting nut (3) is arranged on the forceps head (2), an adjusting block (7) is slidably arranged on the lower edge of the forceps head (2), the adjusting block (7) is meshed with the adjusting nut (3), a fixed clamp (10) is arranged on the forceps head (2), the lowest point of the fixed clamp (10) is lower than the lowest point of the connecting part (6), a movable clamp (8) is arranged on the adjusting block (7), and the fixed;

clamping teeth (9) are arranged on the inner sides of the fixed clamp (10) and the movable clamp (8), and the inner side surface of the movable clamp (8) is an arc surface;

the nut open slot (5) is a multi-specification open slot;

when the expansion pipe is used, firstly, a nut on an expansion screw is screwed out by utilizing a nut opening, a fixed clamp (10) is abutted to the inner side of an expansion pipe, an adjusting nut (3) is rotated, the adjusting nut (3) drives an adjusting block (7) to slide along a binding clip (2) and move to one side of the fixed clamp (10), as the binding clip (2) is obliquely arranged, the entering direction of a movable clamp (8) is oblique, the fixed frame and the movable clamp (8) tightly clamp a sleeve, then a clamp handle (4) is pressed downwards by taking the bottom of a connecting part (6) as a fulcrum, the expansion pipe applies force to an orifice by utilizing a lever principle, the clamping point positions of the fixed clamp (10) and the movable clamp (8) are gradually adjusted, the expansion pipe is pulled out, and then the expansion bolt is taken out;

the purpose of pulling out the sleeve by the lever principle is achieved.

Claims
