Description

Step-less adjustment spinning spanner

Technical field:

The utility model relates to a kind of spanner, especially the cleaner spanner.

Background technology

Existing a kind of cleaner spanner is made up of pincers band, adjusting support, handle, alignment pin.The pincers band is that one one end is hinged at the steel band of handle front portion, and steel band can have rubber antiskid layer or canvas skid resistant course or the compound skid resistant course of rubber duck concurrently, and the back segment of pincers band has a plurality of locating holes to cooperate the free end of locking pliers band with the alignment pin of handle front end; Regulate support and be provided in a side of pincers band pin joint front and have pincers and hold the support of cambered surface, pincers are held cambered surface and can be had skid resistant course concurrently; This spanner is difficult to be adjusted to meet the size of being pulled the thing diameter fully owing to the locating hole of pincers band back segment all is spaced a distance, and therefore runs into oil surface how and skids easily, influences result of use.

Other has a kind of random accent cleaner spanner to meet the size of being pulled the thing diameter with clamping to be be adjusted to, this spanner has the pincers band equally, regulates support, handle, the free end of pincers band connects a bolt, the rear end of handle is provided with pincers and is with free-ended bolt nut engaged, the turn nut can be controlled the bolt advance and retreat, meet the size of being pulled the thing diameter fully thereby the pincers band is adjusted to, be with the loose skidding that causes because of pincers when avoiding using.But this random accent cleaner spanner is when shrinking the pincers band, and pincers are with free-ended bolt to stretch out toward the handle rear, and the bolt that stretch out at the handle rear counteracts to operation to a certain extent, especially is subjected to certain limitation in the narrow space operation.

Also have a kind of when shrinking the pincers band, screw rod still remains on original position, the step-less adjustment spanner that can stretch out toward the handle rear not, this spanner has the pincers band equally, regulates support, handle, the free end of pincers bands and the welding of the side of a nut are equipped with in the handle and the screw rod that clamps the nut cooperation that the band free end is connected, and the rear end of screw rod is fixed on the driver center of handle rear end, for ease of the turn screw rod, done embossing around the driver.This spanner has easy to operate technique effect.But assembling the time need be equipped with free end and nut that welding equipment will clamp band and weld, and in addition, the interior screw rod of handle is pulled out from the rear end of handle easily, may cause screw rod to damage, and influences the normal use of spanner.

The utility model content

The utility model technical issues that need to address provide a kind of easy to assembly and can keep the step-less adjustment spanner of normal running.

The technical solution of the utility model comprises the square tube type handle and be hinged at the pincers band of handle front portion, be located at pincers band pin joint front has pincers and holds the adjusting support of cambered surface, the screw rod that the rear end is connected with driver, it is characterized in that clamping the free end of band and wing riveted joint that one is contained in the rectangular-shaped body in the handle square tube, another wing center of this rectangular-shaped body be shaped on be contained in handle in the screw that cooperates of screw rod; Be shaped on a circle groove on the screw rod of driver front side, be inserted with forked folder in the groove, be with locating piece on the body of rod between forked folder and the driver, the side of this locating piece is shaped on screw, and locating piece is fixed at handle rear end by the pilot hole of handle rear end with fixed screw.

The utility model has been cancelled the welding assembly process owing to adopt the rectangular-shaped body of a band of the free end riveted joint screw of being with at pincers to substitute the assembling mode of welded nut, not only makes assembling convenient, has also improved assembly quality; In addition, handle rear end is provided with locating piece remains in the handle screw rod, and screw rod can not pulled out from the rear end of handle, can avoid the screw rod damage, has easy to operate, the normal effect of using of protection spanner.

The specific embodiment

The utility model adopts square tube type handle 3 and is hinged is with 1 at the pincers of handle 3 front portions, pincers are with 1 can have skid resistant course concurrently, pincers with 1 with handle 3 hinges can be directly hinged or adopt two two ends to have the connecting plate 5 of pin-and-hole to be connected, two connecting plates 5 are symmetrically placed in the both sides of handle 3 anterior hinge holes, are with 1 to be hinged with handle 3 and pincers respectively with swivel pin 6,7;

Pincers are with a free end of 1 and a flank riveted joint that is contained in rectangular-shaped body 4 (see figure 2)s in handle 3 square tubes, and another wing center of this rectangular-shaped body 4 is shaped on the screw that the screw rod 8 interior with being contained in handle 3 cooperates;

Be provided with the band pincers at pincers with 1 pin joint front and hold the adjusting support 2 of cambered surface, the pincers of adjusting support 2 are held cambered surface and can be had skid resistant course concurrently;

Screw rod 8 rear ends are connected with driver 9, be shaped on a circle groove on the screw rod 8 of driver 9 front sides, be inserted with forked folder (Fig. 4) in the groove, be with locating piece (Fig. 3) on the body of rod between forked folder and the driver 9, the side of this locating piece is shaped on screw, and locating piece is fixed in handle 3 rear ends by the pilot hole of handle 3 rear ends with fixed screw;

Feel is better when having done embossing, rear portion around the driver 9 and making the spherical use of semicircle.
