Abstract
The utility model relates to a magnetic extension rod, which comprises a rod body, wherein the two ends of the rod body are respectively provided with a connecting segment connected with a sleeve and a connecting segment connected with a wrench, a cylindrical body is arranged at top of end parts of the connecting segment connected with the sleeve in a protruding way, a pit is arranged on the cylindrical body, a magnetic body is filled in the pit, the connecting segment, connected with the sleeve, of the rod body, is also provided with an elastic limitation element, the elastic limitation element comprises a hole, a marble and a spring, the hole, the marble and the spring are arranged on the side wall of the connecting segment connected with the sleeve. The marble is arranged on the spring, the spring is jacked up and filled in the hole, a local part of a marble body extends out of the hole, and a grab part at the middle of the rod body is also provided with knurling. The top end is provided with the magnetic body, a fastening element can be easily sucked after the sleeve or other tool heads are sleeved on the magnetic body and is prevented from sliding and falling, a falling part and the like can be picked up at a narrow position, the magnetic extension rod is convenient to operate, and labor efficiency is improved; moreover, the connecting part is provided with the elastic limitation element, and the defect of difficulty in disassembly caused by poor tightness matching during connecting, time waste, labor waste or easiness in disconnection are overcome.
Description
Technical field
The utility model belongs to the accessory of combined type hardware ﹠ tools, specifically a kind of band magnetic extension bar.
Background technology
From the technical staff who repairs and install assembling cognition is arranged, when operation, all can use pliers, screwdriver, spanner etc. instrument, volume is very large if whole equipments of special purpose single-piece get up, carry and take in all very inconvenient, a lot of multiplex collapsible tools of doing has appearred now on the market, be contained in the chest, in order to hold more instrument and weight reduction, manufacturer improves instrument again, as with spanner, screwdriver, box spanner, the handle of double offset ring spanner is integrated, specifically they are made knockdown, share a handle and can connect tool heads a plurality of different sizes or shape in the end, the connecting rod that instrument has so just been arranged, but connecting rod also makes the cooperation when being connected with tool heads of extension bar be difficult to control, cooperate tension dismounting inconvenience, too pine throws off easily, and extension bar does not have other purposes yet.
The utility model content
The utility model provides a kind of band magnetic extension bar that can be used for holding small-sized metal piece, easy accessibility, can not throw off.
The technical scheme that realizes the utility model purpose is to adopt at extension bar a magnetic to be set, can hold screw like this, screw, securing members such as nut or fall into finding in the slit of equipment, at the position that is connected with tool heads one elastic limit device is set in addition, specifically comprise the body of rod, body of rod two ends are respectively with the linkage section that is connected with sleeve, the linkage section that is connected with spanner, the top of the end of the linkage section that is connected with sleeve also protrudes out column, this column is provided with pit, be filled with magnetic in the described pit, just there has been magnetic the extension bar termination like this; The linkage section that is connected with sleeve of the described body of rod also is provided with elastic spacing one in addition, it is made of the hole, hoodle, the spring that are located at the linkage section side-walls that is connected with sleeve, hoodle is upper, and lower top spring is loaded in the hole, and the Local Convex of hoodle pearl body is for outside the mouth of hole; For grasped firmly can not skidded, can also do annular knurl at body of rod middle part and process.
A kind of band magnetic extension bar of the present utility model, owing to be provided with magnetic at top end, make it after suit upper bush or other tool heads, can hold easily securing member, can not skid and come off, can also pick up in narrower and small position the part that falls down etc., namely made things convenient for operation, can raise labour efficiency again, add elastic spacing one at connecting portion in addition, eliminate when being connected with tool heads degree of tightness and cooperated and badly cause that dismounting is difficult for, waste time and energy, or the defective of throwing off easily.

The specific embodiment
Below in conjunction with embodiment the utility model is further described, following each embodiment only is used for the explanation the technical solution of the utility model, but to not restriction of the utility model.
Embodiment one
As shown in Figures 1 to 4, band magnetic extension bar of the present utility model, it has linkage section 1b, the linkage section 1a that is connected with spanner that an end of the body of rod 1, the body of rod 1 is connected with sleeve, there is a projection 1c end of the linkage section 1b that sleeve connects, projection 1c is provided with pit 1c1, have hole 1b1 on the sidewall of the linkage section 1b that sleeve connects, be processed with annular knurl 1d on the body of rod 1, the linkage section 1a that is connected with spanner has square hole 1a1.Magnetic 4 is filled among the pit 1c1, its shape size and pit 1c1 inner chamber are complementary, hoodle 3 is upper, spring 2 is seated among the 1b1 of hole in the lump lower, spring 2 is outside the 1b1 mouth of hoodle 3 partial top emersions hole, and hoodle 3 is exposed the linkage section 1b surface that is connected with sleeve by jacking height is less than its radius.
Certainly the band magnetic extension bar in above-mentioned, the projection 1c diameter that setting-in magnetic 4 is set can enlarge and dwindle, and shape also can change, and the linkage section 1b end that perhaps will be connected with sleeve prolongs also passable.
Claims (3)
1. be with the magnetic extension bar for one kind, comprise that the body of rod, body of rod two ends are respectively with the linkage section that is connected with sleeve, the linkage section that is connected with spanner, it is characterized in that: the top of the end of the linkage section that is connected with sleeve also protrudes out column, this column is provided with pit, is filled with magnetic in the described pit.
