Abstract
The utility model relates to a three-claw clip type movable socket spanner, which consists of a socket (1), a movable claw (3), a feeding ring (9) and an end cap (8). The lower end of the socket (1) is provided with a movable groove (10) while the upper end thereof is provided with a feeding ring groove and a spanner inserting hole (2), the movable claw (3) is provided with an involute spiral groove (4) and anti-skidding teeth (5) and can radially move inside the movable groove (10), the lower end of the feeding ring (9) is provided with an involute spiral line nosing (11) while the upper end is provided with a rotary handle (6) and a positioning claw (12), the feeding ring rotates in the socket, the end cap (7) is fixed on the socket (1) through threads, and the upper end of the end cap is provided with positioning teeth (8). The rotary handle adjusts peripheral diameter of the movable claw so as to match with nuts with different sizes, threaded stress on the feeding ring is balanced by utilizing a three-point positioning form, and peripheral diameters of the positioning claw and the movable claw which are provided with positioning mechanisms lead the socket spanner and the nuts to be matched more tightly and stably, thereby avoiding damaging the nuts and the spanner due to loosening.
Description
Technical field
The utility model relates to machine-building, is mainly used in the nut dismounting of different size, the nut of different size for convenience detach, and solution difference because of nut when a teardown of engine is repeatedly changed spanner and sleeve, reduces the instrument amount of carrying.
Technical background
The use of China's box spanner is very general, and the ordinary cartridge spanner all is at a kind of nut model, so workman or the family box spanner that must be equipped with a lot of different models could satisfy and installs and maintenance work.The normal activity spanner adopts two point form location and worm drive feeding, be out of shape by force unbalance to make the location inaccurate and looseningly easily can destroy nut when serious because of worm tooth in operating process.The box spanner of China has only single size mostly at present, and monkey wrench also is two point locations.For example China Patent No. CN1392028 fast adjustable spanners just simply adopts two ends activity simultaneously to make the location faster on general monkey wrench, but its location clamps also can be unstable more, also can produce the loosening phenomenon of contact, not solve the problem of worm thread distortion.Its work of patent No. CN1463827 box spanner is the operation axle that is rotated by the operating grip parts for another example, be formed with the cylinder body of sawtooth pattern track gear tooth within it on the side face, be installed in first speed changer of strengthening torque in the cylinder body with first change operation shaft torque speed simultaneously, be installed in the cylinder body to change once more that torque speed is strengthened torque simultaneously so that rotate second speed changer that receives bolt that will degree of tightness with stronger power, and be fixed on the carriage that extends from the protecgulum that is installed on the cylinder body front end and be used to receive the support component of other bolt of the bolt that vicinity will degree of tightness.Its structure is more complicated and can only can not cooperate with the nut of different size easily at the nut of single size than ordinary cartridge.
Summary of the invention
The problem that the utility model solved: solve the worry that dismounting different size nut will constantly be changed sleeve, adopt three-point fix mode and locking gear to make the reliable stressed even dismounting in location convenient in economizing.
Function of the present utility model is achieved in that by sleeve, movable claw, feed ring and end cap to be formed; The sleeve lower end has the loose slot upper end and has feeding annular groove and spanner jack, movable claw has involute helicla flute and anti-slop serrations and can do radial motion in loose slot, the feed ring lower end is provided with the prominent edge of involute helical, the upper end is provided with a pair of rotating handle and locating detent, feed ring rotates in sleeve, end cap is fixed on the sleeve by screw thread, and rotating handle and locating detent part external part cover end face; Inboard, end cap upper end has a circle zigzag positioning tooth, by locating detent and cooperating step by step of positioning tooth locating feed ring.When the dismounting nut, rotate rotating handle and drive the feed ring rotation, the helix of gradually opening on the feed ring drives movable claw and will do stepless tightening along loose slot and move, feed ring is located and locked to locating detent on the rotating handle on the positioning tooth on the end cap, plug the spanner pivoted arm simultaneously on the spanner jack on the sleeve and just can dismantle.
The utility model is regulated the nut of the circle diameter cooperation different size of movable claw by rotating handle, adopt the screw thread stress on the three-point fix mode balance feed ring, be provided with detent mechanism accurately and reliably the circle diameter of geocoded activity pawl make between box spanner and the nut and to cooperate more closely and firm, reduce loosening infringement to nut and spanner.
The beneficial effects of the utility model: reduce the trouble of dismounting mechanical process, reduce the amount of carrying of instrument, quickly and easily the nut of supporting different size.

Among the figure, 1 sleeve, 2 spanner jacks, 3 movable claws, 4 helicla flutes, 5 anti-slop serrations, 6 rotating handles, 7 end caps, 8 positioning tooths, 9 feed rings, 10 loose slots, the 11 helicals edge of dashing forward, 12 locating detents.
The specific embodiment
With the dismounting nut is example.At first rotate rotating handle 6 and drive feed ring 9 rotations, the helix of gradually opening on the feed ring drives movable claw 3 and will do stepless tightening along loose slot and move, when movable claw 3 is firmly grasped nut, feed ring 9 is located and locked to locating detent 12 on the positioning tooth on the end cap 78, plug the spanner pivoted arm simultaneously on the spanner jack 2 on the sleeve 1 and just can dismantle.
