Abstract
The invention relates to a multipurpose quick tool having replaceable teeth, which is suitable for being used for quickly tightening or loosening various nuts (bolts) and pipes and twisting abnormally shaped workpieces. The tool comprises a handle, a hook-shaped jaw and a spring fixing structure, wherein the head is in a semi-circular shape; the whole semi-circular part is a detachable and exchangeable replaceable tooth; an anti-sliding toothed part of a jaw head ventral part is also a detachable and exchangeable replaceable tooth; the back parts of the two detachable and exchangeable replaceable teeth are both provided with bayonets; the bayonets have a shape of forked tail, thereby preventing the replaceable teeth from dropping off; and a replaceable tooth fixing pin nail is inserted into each replaceable tooth from the head part of the jaw, in order to prevent the replaceable teeth from sliding aside.
Description
Affiliated technical field:
The present invention relates to a kind of replacement tooth and use presto tool more, this instrument is applicable to be tightened fast or unclamps various nuts (bolt), water pipe and the special-shaped workpiece of twisting.
Background technology:
The hand tools that generally is used to tighten or unclamps the special-shaped workpiece of various nuts (bolt), water pipe and twisting is polytype spanner, plumbing combination pliers etc.Though Chinese patent 93218174.0 has possessed above-mentioned all kinds of function, constitute a multi-purpose fast ratchet wrench, but in concrete real the work, though this spanner under normal operating position, the time one of use is long, the crown meeting rust of this kind spanner, when the interlock workpiece, just have the phenomenon of skidding and occur, this spanner can't be used, not only influenced operating efficiency, but also can make this instrument owing to the reason of tooth causes too early scrapping, be unfavorable for resources conservation.Thereby there is certain defective in Chinese patent 93218174.0.
Summary of the invention:
The objective of the invention is to provide a kind of improved replacement tooth to use presto tool, it can overcome the defective of above-mentioned existence effectively, increases the service life more, improves long-acting rate of its work and the saving that helps resource.
The object of the present invention is achieved like this:
Replace tooth how with presto tool by handle, collude that shape is pulled mouth and spring-fixed structure constitutes, its head is semicircle shape, semi-circular portions has anti-slop serrations, whole semi-circular portions is a replacement tooth that can unload and change, replacing the tooth rear portion has a down to go into the formula bayonet socket, and this bayonet socket is dovetail shaped, prevents to replace tooth and comes off, replace flank to slip for preventing simultaneously, have a replacement tooth fixing pin to enter the replacement tooth from handle body front portion; The semicircle lower head has a strip notch, pulls metastomium to hold the shape that colludes that inserts in the strip notch, and by pin this is colluded shape and pull metastomium and be fixed in the strip notch, makes hook-shaped pulling mouthful do free opening and closing with the pin for center of circle fixing point; Spring-fixed structure mainly is made of spring: the spring steady pin crosses the strip notch, become the sufficient fixed pivot that twines on it of spring one end, spring other end foot penetrates or contacts and colludes the insertion bar bore portion that shape pulls mouthful and form another fulcrum, it acts on operates when circling round, pull mouth and under the tension force of spring supports, can reset very soon, for next one twisting action is got ready; Pull oral belly and back anti-slop serrations is all arranged, the anti-slop serrations of belly is a replacement tooth that can unload and change, replacing the tooth back has a down to go into to pull the replacement tooth bayonet socket of oral belly, this bayonet socket is dovetail shaped, to prevent that replacing tooth comes off, there is a replacement tooth fixing pin to enter the replacement tooth, to prevent replacing flank to slip from pulling oral portion.
Replace the application of tooth in this instrument, prolonged the service time of instrument, make it become a kind of economical and practical instrument, thereby also saved natural resources greatly.
Description of drawings:
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a plane structure chart of the present invention.
Among the figure 1, the handle body, 2, pull mouth, 3, spring-fixed structure, 4, handle body semicircle shape head, 5, semicircle head anti-slop serrations, 6, handle body semicircle head is replaced tooth, 7, handle body semicircle head is replaced tooth fixing pin, 8, strip-shaped grooves, 9, pull metastomium, 10, pin, 11, spring, 12, spring steady pin, 13, spring terminal foot fixed pivot, 14, another fulcrum of spring terminal foot, 15, opening, 16, pull oral belly anti-slop serrations, 17, pull a mouthful back anti-slop serrations, 18, pull oral belly and replace tooth, 19, handle body semicircle head is replaced tooth and is pulled oral belly and replace tooth rear portion dovetail shaped bayonet socket, and 20, pull oral belly and replace the tooth fixing pin.
The specific embodiment:
Among Fig. 1, pull mouthful (2) under the effect of spring (11) tension force, to pull mouthful (2) upwards withstands, make to pull and form an opening (15) between oral belly anti-slop serrations (16) and the handle body semicircle shape head (4), handle body semicircle shape head anti-slop serrations (5) and pull oral belly anti-slop serrations (16) in order to the interlock workpiece, to prevent workpiece, particularly round piece slippage from opening (15).Pull mouthful back anti-slop serrations (17) when being used for shut-down operation, thumb is pulled mouthful (2) and is discharged workpiece; Spring-fixed structure (3) is by spring (11), spring steady pin (12), strip-shaped grooves (8) and pull metastomium (9) and form.Spring steady pin (12) crosses strip-shaped grooves (8), becomes spring (11) one ends foots and twines fixed pivot (13) on it, and spring (11) other end foot penetrates and colludes shape and pull the insertion bar bore portion of metastomium (9) and form another fulcrum (14).Fix in case lateral sliding is pulled oral belly replacement tooth (18) and fixed in case lateral sliding by replacing tooth fixing pin (20) by tooth fixing pin (8) by replacing for handle body semicircle head replacement tooth (6).Handle body semicircle head is replaced tooth (6) and is pulled oral belly replacement tooth (18) rear portion bayonet socket and all becomes to be dovetail shaped (19), to prevent that replacing tooth comes off.
Claims (2)
1. a replacement tooth that is used for various nuts (bolt), water pipe and special-shaped workpiece is used presto tool more, this instrument comprises handle body (1), hook-shaped mouthful (2) and the spring-fixed structure (3) pulled, it is characterized in that handle body head is semicircle shape (4), whole semi-circular portions is for replacing tooth (6), replacing the tooth rear portion has a bayonet socket to be dovetail shaped (19), and a replacement tooth fixing pin (20) should be replaced tooth (6) and be fixed on the handle body.
