Abstract
The present invention relates to technical field of hand operated tool, and particularly to a fork spanner. The fork spanner is mainly composed of a spanner body, a crescent spanner head 1 and a spanner head 2. The crescent spanner head 1 and the spanner head 2 are positioned at two ends of spanner body. The middle of wrench body is provided with a valve drawing device circular hole. The crescent spanner head 1 and the spanner head 2 are punched to projected nut grooves with two standards. The hand operated tool of the invention has the advantages of simple structure, low cost and convenient use and carrying.
Description
Technical field:
What the present invention relates to is the hand-operated tools technical field, is specially fork spanner.
Background technology:
Existing fork spanner function singleness assembles, keeps in repair, will use when safeguarding the fork spanner of plurality of specifications usually at machinery, one can not be lacked, and uses, carries all inconvenient, and loses easily.Therefore existing fork spanner instrument has that volume is big, manufacturing cost is high and uses, carries all problem such as inconvenience.
Summary of the invention:
The purpose of this invention is to provide a kind of combination fork spanner, thereby overcome the deficiencies in the prior art.
Technical solution of the present invention is: fork spanner mainly is made up of wrench body, crescent wrench 1 and wrench 2, crescent wrench 1 and wrench 2 are at the two ends of wrench body, in the middle of the wrench body valve drawbench circular hole is arranged, crescent wrench 1 and wrench 2 punching presses have the nut groove of the convex of two kinds of specifications.
The present invention is simple in structure, cost is low, use advantage easy to carry.
Description of drawings:
The present invention is described in detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention
Among the figure: 1. the nut groove 2 of nut groove 1 6. convexs of wrench body 2. crescent wrench 1 3. crescent wrench 24. valve drawbench circular holes 5. convexs
The specific embodiment:
In the drawings, the combination fork spanner mainly is made up of wrench body (1), crescent wrench 1 (2) and wrench 2 (3), crescent wrench 1 (2) and wrench 2 (3) two ends at wrench body, there are valve drawbench circular hole (4), crescent wrench 1 and wrench 2 punching presses that the nut groove 1 (5) of the convex of two kinds of specifications, the nut groove 2 (6) of convex are arranged in the middle of the wrench body (1).This combination wrench material is a 45# punching block forging molding, through punching and edge-cutting, the nut groove 1 (5) of convex, the nut groove 2 (6) of convex are through punch forming, reach dimensional requirement through slotting machine fine finishining again, valve drawbench (4) punches, reaches dimensional requirement through the type of being hinged into through drilling machine, semi-finished product through meshbeltfurnace quench, tempering reaches hardness standard, by carry out zinc-plated behind the polishing machine polishing grinding or chromium plating to finished product.
In use, use the preceding auspicious part of the nut groove 2 (6) of the nut groove 1 (5) of crescent wrench 1 (2) and wrench 2 (3) convexs and convex during degree of tightness large size nut, use crescent wrench 1 (2) and the nut groove 1 (5) of wrench 2 (3) convexs and nut groove 2 (6) rear end parts of convex of this fork spanner during degree of tightness trumpet nut; When being used for the dismounting diesel engine spiracle, get final product with the valve drawbench circular hole (4) of this spanner.
Claims (1)
1, fork spanner, form by wrench body, crescent wrench 1 and wrench 2, it is characterized in that: crescent wrench 1 and wrench 2 have valve drawbench circular hole at the two ends of wrench body in the middle of the wrench body, and crescent wrench 1 and wrench 2 punching presses have the nut groove of the convex of two kinds of specifications.
