Description
Technical field
The utility model relates to a kind of hardware installation and maintenance tool, especially a kind of interior box spanner.
Background technique
Pipe fitting (or pipe fitting joint) is during installation and maintenance, since: pipe fitting is embedded in wall or to protect outer surface
Screw thread or avoid outer surface from generating the reasons such as catcher mark, cannot be dismantled with pliers clamping pipe fitting outer wall is directlyed adopt, example
There is fracture of wire situation in such as tap angle valve fracture of wire, and more professional way is using withdrawing device for broken threaded parts, withdrawing device for broken threaded parts and spiral shell
Line equally divides left-handed and dextrorotation, and when use should select the extractor oppositely oriented with pipe fitting, and extractor is inserted into pore, is used
Spanner rotates extractor, to take out pipe fitting.Withdrawing device for broken threaded parts needs to select model, and needs that spanner is cooperated to use, operation
It is complex.
Utility model content
The purpose of the utility model is to overcome the above deficiencies in the existing technologies, and it is more simple to provide a kind of operation
Single interior box spanner.
The technical scheme in the invention for solving the above technical problem is:
A kind of interior box spanner, including left caliper, right caliper body, the right upper portion of the left caliper and the left upper portion of right caliper body
Hingedly, it is characterised in that: there is elastic component, side upper end, the right side of left caliper between the right side of left caliper and the left side of right caliper body
Integral type fixes two link block one end respectively for the side upper end of caliper, from one end of link block to the other end of link block, connects
The section for connecing block is gradually reduced, the upper surface edge of left caliper and right caliper body and the edge junction for being correspondingly connected with block one end, connection
One end (pressing plate is for protruding into pore and applying pressure to pore inner wall) of integral type fixation clip, the pressing plate on the other end of block
Outer wall be in evagination globoidal structure, offer anti-skid chequer on the globoidal structure.It, will when box spanner operates in the utility model
Two pressing plates are inserted into pore, hand pressure left caliper, right caliper body, so that the upper end of the upper end of left caliper, right caliper body moves backwards,
Pressing plate protrudes into pore and applies pressure to pore inner wall, rotate in box spanner, pass through the frictional force between pressing plate and pore inner wall, it is real
The operation of pipe fitting is now rotated, the utility model inner tube clamp structure is simple, easy to operate, the installation suitable for different size tubulars
Occasion is repaired, the structure setting of pressing plate is reasonable, and more compact, structural strength is higher.
Preferably, the medial surface and left caliper of link block on the medial surface of the link block on left caliper, left caliper
Medial surface
Upper end is in same plane, the medial surface of the link block on right caliper body, link block on right caliper body medial surface and
Right caliper body
Medial surface upper end be in same plane.
Preferably, elastic component uses pressure spring.
Preferably, anti-skid chequer is made of several helical slots being set in distance.
Preferably, anti-skid chequer is made of several linear types fluting being set in distance.
Preferably, the lower part of the lower part of left caliper, right caliper body is provided with Anti-slip cover.
Preferably, link block is in half truncated cone-shaped structure.
The utility model compared with prior art, has the following advantages that and effect: the clamp structure letter of the utility model inner tube
Single, easy to operate, suitable for the installation and maintenance occasion of different size tubulars, the structure setting of pressing plate is reasonable, more compact, structure
Intensity is higher.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is pair
The explanation of the utility model and the utility model is not limited to following embodiment.
Referring to figures 1-4, box spanner in the present embodiment, including left caliper 1, right caliper body 2, on the right side of the left caliper 1
The left upper portion of portion and right caliper body 2 is hinged, has elastic component 3, left caliper 1 between the right side of left caliper 1 and the left side of right caliper body 2
Side upper end, right caliper body 2 integral type fixes two 4 one end of link block respectively for side upper end, from one end of link block 4 to even
The other end of block 4 is connect, the section of link block 4 is gradually reduced, and the upper surface edge of left caliper 1 and right caliper body 2 and is correspondingly connected with block 4
The edge junction of one end, (pressing plate 5 is for protruding into pore and applying for one end of integral type fixation clip 5 on the other end of link block 4
