Description
Technical field
The utility model relates to a kind of instrument extension bar, particularly relates to a kind of easily assembled magnetic instrument extension bar.
Background technology
The box spanner of general conventional construction, when getting loose screw piece, screw piece can come off voluntarily and drop out, and this kind design can cause the inconvenience in the work in practice; Industry is the absorption relation in order to realize screw piece and the sleeve of pulling pine, so sleeve inner is provided with a spring and a magnetic,, utilizes the magnetic characteristic of magnetic so that when pulling loose screw piece, the screw piece that the spiral shell demolition is unloaded is taken advantage of a situation and is adsorbed in the sleeve, and screw piece was taken out in the very first time.
Though this kind mode is convenient, but because the size of sleeve is various, so in each sleeve, all be provided with a spring and a magnetic, then it promptly seems on cost and does not have an economic benefit, and installation one spring and a magnetic also can cause the assembling speed of sleeve integral body slow in each sleeve, for this reason, just industry improves out again as No. 483361, Taiwan patent announcement, name is called the patent of " structural improvement of box spanner ".As shown in Figure 8, it makes sleeve and box spanner be one by a screw and sets firmly relation, be provided with a perforation in the sleeve root edge again, this perforation can cover card for the location of an interior tool magnetic, so, in the time will changing the sleeve of different size, only need the positioning sleeve of sleeve root edge is taken out, insert again in the perforation of another sleeve root edge, can reach the effect that different sleeves can use, improve that above-mentioned spanner need be provided with all in each sleeve that a spring and a magnetic caused expensive and assemble loaded down with trivial details shortcoming.Yet, the spanner of this structure also has following described shortcoming in the use: the existing box spanner of commonly using of this kind improvement, in the time will using the sleeve of different size, after needing to set firmly the screw dismounting of sleeve earlier, again with the positioning sleeve taking-up of sleeve root edge and the sleeve root edge of inserting another size, its replacing program is numerous and diverse, can cause changing the shortcoming of positioning sleeve time and effort consuming.
In addition, No. 478433, Taiwan patent announcement, name is called " hand-held tool adsorption structure ", as shown in Figure 9, it mainly is to utilize a Wrench, this Wrench can be pulled for open-end wrench or double offset ring spanner cover card, and this Wrench one end is provided with an accommodation chamber, can be installed with the body of a spring and a tool magnetic in this accommodation chamber, at last, relend by the punch process mode, the accommodation chamber formation one of Wrench is supported, borrow this to come off to spring and body that edge can prevent to be installed with in accommodation chamber.During use, Wrench is located in sleeve one end, again with sleeve other end cover card one screw piece, relend by an open-end wrench (or double offset ring spanner) turn Wrench, and then make sleeve can unscrew screw piece in the lump, when screw piece gets loose, can pass through the body of tool magnetic in the Wrench accommodation chamber, and realize absorption screw piece.
Above-mentioned existing spanner though can utilize the Wrench of a pivot bush unit, cooperates the different size sleeve to use, and the existing spanner of this kind need utilize impact style that Wrench is formed with one and support edge, comes off to prevent spring and body; The downforce of well-known punch process is quite big, desire makes the less Wrench accommodation chamber of structural volume be formed with one and supports edge, necessary SC in the control of mechanical pressure, as careless slightly promptly can be because of stamping press the excessive or accurate heart deviation of punching press, and cause the distortion of Wrench overall appearance, and then cause the fraction defective of Wrench to heighten.
This shows that the Wrench extension bar of above-mentioned existing pivot bush unit still has many defectives, and demands urgently further being improved.
The problem that exists for the Wrench extension bar that solves pivot bush unit, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.
Because the defective that the Wrench extension bar of above-mentioned existing pivot bush unit exists, the design people is based on abundant practical experience and professional knowledge, actively studied innovation, through constantly research, design, and after studying sample and improvement repeatedly, create the utility model that has practical value finally.
