Abstract
The utility model discloses a fixing wrench for a connecting piece of a gas cylinder, composed of a handle (2), a tiger paw (3), tiger teeth (4) and a cross-grain protrusion (1). The tiger paw (3) is extended toward two edges to enclose a semicircular hukou with a trumpet-shaped inner chamber, the two ends of the tiger paw (3) are respectively provided with the tight teeth (4), and the two tiger teeth extend toward the direction of the center of circle of the chamber of the hukou to form a trumpet-shaped bayonet in a shape like a Chinese character 'ba'. The problem that no special tool is used for mounting and dismounting the connecting piece of the gas cylinder in the prior art is solved. The utility model has the advantages of convenient and safe use, etc. and can be widely used for mounting and dismounting the connecting pieces of various gas cylinders.
Description
The utility model relates to a kind of fuel gas bottle connector spanner, more particularly, relates to a kind of fuel gas bottle pressure-reducing valve spanner.
In the prior art, there is not special-purpose fuel gas bottle pressure-reducing valve spanner, when need taking off or load onto pressure-reducing valve, people all feel very inconvenient when taking a breath, not that hand can not be stretched and can't be removed stage makeup and costume, be in the way exactly and do not make power, it is very inconvenient again to use other to substitute instrument, thereby must have specific purpose tool could adapt to this needs.
The purpose of this utility model is to provide a kind of specific purpose tool, to solve the problem of removing stage makeup and costume of the different big or small pressure-reducing valves of fuel gas bottle.
In order to achieve the above object, the utility model has adopted following technical scheme: design a kind of spanner, have handle (2), brave pawl (3) and protruding canine teeth (4), the uniform brave pawl of radian (3) surrounds an inner chamber to the both sides extension and is trumpet-shaped semicircle tiger, respectively there is a protruding canine teeth (4) at the two ends of tiger pawl (3), two protruding canine teeth stretch out and form trumpet-shaped " eight " font bayonet socket to the center of circle in tiger chamber direction, and band (1) projection is arranged on the handle (2).
In implementing process of the present utility model, should be noted that: the radian of brave pawl (3) is wanted evenly and its inner chamber should be a trumpet-shaped semicircle tiger, can make it identical with circular pressure-reducing valve outer like this, horn-like can the adaptation, adorned and the requirement of unloading different size diameter pressure-reducing valves; In addition, two protruding canine teeth should form trumpet-shaped " eight " font bayonet socket, make protruding canine teeth form a comparatively sharp-pointed tip, not only are convenient to operation, and it is tighter to block the outer of pressure-reducing valve, unlikelyly skid when twisting; Handle has the band projection on (2), is convenient to hold and not landing, makes easy to operate.The utility model can be made of engineering plastics or tool steel, and is sturdy and durable, as making of engineering plastics, then can prevent to produce spark and safer.
Compared with prior art, the utlity model has following tangible advantage: the tiger inner chamber that brave pawl (3) forms is a trumpet-shaped semicircle tiger, can make it identical with circular pressure-reducing valve outer, horn-like can the adaptation, adorned and the requirement of unloading different size diameter pressure-reducing valves; In addition, two protruding canine teeth have formed trumpet-shaped " eight " font bayonet socket, and a comparatively sharp-pointed tip is arranged before the protruding canine teeth, not only are convenient to operation, and it is tighter to block the outer of pressure-reducing valve, unlikelyly skid when twisting; Handle has the band projection on (2), holds during operation to be difficult for landing and to fall on the ground.Therefore, the utlity model has easy to operate, safe and reliable advantage.
Below in conjunction with accompanying drawing the utility model is done further explanation: Fig. 1 is a front view, and Fig. 2 is an A-A face cutaway view, and Fig. 3 is a side view; 1 is the band projection among the figure, the 2nd, handle, the 3rd, brave pawl, the 4th, protruding canine teeth, as can be seen from the figure: the uniform brave pawl of radian (3) surrounds an inner chamber to the both sides extension and is trumpet-shaped semicircle tiger, respectively there is a protruding canine teeth (4) at the two ends of tiger pawl (3), and two protruding canine teeth stretch out and form trumpet-shaped " eight " font bayonet socket to the center of circle in tiger chamber direction, and band (1) projection is arranged on the handle (2).
