Abstract

A universal strong spanner rod able to change its shape and performance by manually assembling or disassembling screw bolt or nut is composed of a curved rod, a central straight rod, a foldable side rod and a tail rod, and features that the tops of said rods are made into semi-circular holes for connecting fork and pin to form a 7-shaped lever with three movable joints. The middle of the inner side of the connecting fork is provided with a hole assembling positioning nail, a spring ring and a semicircular head, three holes are distributed in the semicircular surface at an angle of 90 degrees, each movable joint can be changed into three different angles and positioned, the movable joint is used for reinforcing the stress sleeve to protect and reinforce the stress strength of the movable joint, and the inner side of the movable joint is provided with a hole assembling stabilizing ball and a spring ring. The operator can change the shape according to the requirements of speed and force for wrenching the bolt and the nut.

Description

The powerful tommy bar of deformable general-purpose

Technical field under this tommy bar is useful for the elasticity bolt nut that needs manually-operated to need very big torsion, but can be deformed into rocking-turn crank fast to the bolt and nut that only needs little torsion.Being useful for needs manually-operated machine-building, installation, maintenance etc.

The existing according to the knowledge of the applicant steam-operating that need use the instrument of very big torsion ability elasticity bolt nut except special use; Outside the electronic specific purpose tool, generally be exactly traditional lever.Such as, now the driver who does transportation with truck has broken not keeping in repair website highway section tire, he must carry out re-type with traditional outfit instrument himself, so, his operation is exactly to find out jack earlier, strip metal lever more than one meter, a small lever of tens centimeter length, a dismounting, the socket wrench specially adapted for it of tire screw, the car body on one side of jack-uping, after making tire liftoff, earlier become flexible lug nut (sometimes with long lever, just the dress tire is at maintenance website wind big gun, play tire machine dress, because using mechanical fixedly indivedual nuts of tire turns round too tightly, and the lever length that is used for back-outing nut is not enough, the torsion Xiao Song that produces not nut) after, change the small lever of tens centimeter length, overturn again and again with the right-hand man, turn to two hands intersects in the time of can not overturning at every turn, nut is only screwed out the distance of 180 ° of corners, each action all gets two hands intersection in addition, like this, not only awkward work efficiency but also low, if the driver uses the strong tommy bar of deformable general-purpose, so, his operation is: find out the powerful tommy bar of jack and deformable general-purpose (ut socket be in the dismounting that is matched on the tommy bar during outside tire only with hand transfer to and broadcast into just can) one side body of jack-uping makes tire liftoff, deformable general-purpose tommy bar is become as shown in Figure 3) 7 font levers come loose nut (as: because of first dress tire is at the maintenance website, with the wind big gun or play tire machine dress, wherein there are indivedual nuts tighter, under the not enough situation of the length torsion of lever, as long as the driver calls in standby common metal water pipe (a bit of) and is placed among the figure adding on the arm of force shown in 11 and can becomes flexible very tight nut once carrying), with time of several seconds the powerful tommy bar of deformable general-purpose is become then and can shake crank, with the circumference rotation, screw out nut fast.

Purpose: raising work is renderd a service in the manually-operated of mechanical industry, substitutes traditional many inconvenience of part and carries, waits slowly when using.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the parts generalized section of utility model.

Fig. 2 Fig. 3 Fig. 4 is the powerful tommy bar embodiment of a deformable general-purpose generalized section.

Composition of content of the present utility model and drawing explanation: (Fig. 1) parts: 1, straight-bars, 3 folding side levers, 4 foot pieces, 5 connect the lever cup heads and contain (locating pin circular hole 10 and is connected pin-and-hole 13), 6 yokes and contain (connecting pin and hole 9), 7 removable movable joints and strengthen stressed cover and contain (cover is stablized pearl and bullet ring 14), 8 and be out of shape locating pins and bullet ring, pullover, the 12 required kits of 11 reinforcings in the middle of the knee, 2.When (Fig. 2) not using, one of them the scheme figure after the distortion; (Fig. 3) 7 font lever shapes during the high tightness bolt and nut of degree of tightness; But moving quick crank shape, structure and the effect of rocking-turn when (Fig. 4) pine twists the bolt and nut of torsion point.

The powerful tommy bar of deformable general-purpose is by the parts mark among the figure, 1,2,3,4 is critical piece, its effect is that the main body in the tommy bar couples together and just becomes the member of main lever, 5 are movable joint connection round end, by a round end, movable joint connects pin-and-hole, and three dowel holes that are used to be out of shape the fixed position, back constitute the distortion location that acts on 180 ° and are connected (three round ends altogether) with lever, 6 for movable joint connects prong, acts on the movable joint round end to be connected.7 is the powerful cover of movable joint, the effect tommy bar becomes straight shape consequence, and all pull folding power, 8 is alignment pin, act on the fixed-site of three angle shape after the per pass movable joint is out of shape, 9 is connecting pin and bolt hole, what act on prong and round end movable joint is connected distortion (totally three prongs), 10 are movable joint round end distortion dowel hole, act on distortion back alignment pin and insert the location, 11 add the arm of force for the corresponding afterburning sleeve pipe of lever, act on to run into the tight bolt of spy, the auxilliary corresponding intensity active force of lever that gives during nut, 12 is the socket wrench specially adapted for it instrument, acts on different bolts, the cooperation of the different size of nut, 13 movable joints connect the round end pin-and-hole, act on the movable joint round end and connect prong, 14 is the powerful cover of removable movable joint location, acts on powerful cover location.

This utility model is compared with prior art, it have rational in infrastructure, be easy to carry, a tool is used more, saving of work and time, can make big torsion, can make the quick hand crank of less torsion again, can carry out various deformation according to the position needs of depositing when depositing.

The applicant thinks, the production that realizes this utility model is used very simple, and the uncomplicated property of its structure has determined the user can use at a glance, has brought easy production also for simultaneously this instrument of manufacturing, and general hardware factory all possesses the working condition ability.
