Abstract

The utility model discloses an adjustable torsion spanner. The adjustable torsion spanner comprises a movable spanner rod, a plurality of longitudinal ratchet bars are disposed on a rod body of the movable spanner rod at intervals, the adjustable torsion spanner further comprises a clamping device, the clamping device comprises two opposite elastic pieces, two ends of each elastic piece are fixedly connected with each other through set screws, middle sections of the two elastic pieces outwards arch respectively to form a clamping groove, bodies of the two elastic pieces, which are close to one of the set screws, are symmetrically provided with clamping grooves which are matched with the ratchet bars, one end of the movable spanner rod is clamped in the groove of the two elastic pieces, adjusting screws which are used for adjusting clamping force are arranged on the bodies of the two elastic pieces between the other set screw and the groove, and a check buckle which can abut against the ratchet bars of the movable spanner rod is punched on one body of one of the elastic pieces. The spanner is adjustable in torsion and convenient to adjust.

Description

The spanner of adjustable torsion

Technical field

The utility model relates to mechanical adjustment tool, is specifically related to a kind of spanner of adjustable torsion.

Background technology

In the prior art, there are two kinds for the spanner of tightening or unclamp bolt or nut, a kind of is the fork spanner that can not regulate torsion, need to be screwed to for some tightening or unclamping work of to a certain degree and not needing to operate again, the spanner that conventionally can use a kind of adjustable torsion operates, when after torsion setting, screwing force reaches after the torsion setting, spanner can skid or dally, and can not produce to screw or nut the problem of over-tightened, also can be laborsaving; The spanner structure of existing adjustable torsion normally adopts sleeve pipe to add the structure that spring adds ratchet and realizes, the torque spanner of this structure, and its complex structure, operation regulates inconvenient.

Utility model content

The purpose of this utility model is, for the above-mentioned defect of prior art, provides a kind of simple in structure, the spanner of adjustable torsion easy to adjust.

A kind of spanner of adjustable torsion is provided, comprise Flexible spanner hand lever, on the body of rod of described Flexible spanner hand lever, interval is shaped with many longitudinal sour jujube bars, also comprise a clamping device, described clamping device comprises two shell fragments that are oppositely arranged, the two ends of every shell fragment are fixed together by hold-down screw, outwards arch upward respectively and form a holding tank in the stage casing of two shell fragments, on the body of two shell fragments near one of them hold-down screw, be arranged with the clamp groove matching with described ratchet bar, one end of described Flexible spanner hand lever is sandwiched in the groove of two shell fragments, in two elastic sheet body between another hold-down screw and described groove, be also provided with the adjustment screw for regulating chucking power size, on the body of a shell fragment, also punching has a non-return fastener that can be against on described Flexible spanner hand lever sour jujube bar therein.

In the spanner of above-mentioned adjustable torsion, also comprise upper cover and lower cover that described clamping device is encased, between upper and lower cover, be connected by screw, the lower limb of upper and lower cover is provided with the combination bore of stretching out for described Flexible spanner hand lever.

In the spanner of above-mentioned adjustable torsion, be also set with shell described upper cover and lower cover outer 1, on described shell, have the through hole corresponding with adjustment screw position.

In the spanner of above-mentioned adjustable torsion, also comprise a conversion sleeve pipe that is enclosed within described Flexible spanner hand lever external part.

The utlity model has following advantage: the utility model adopts the clamping of two shell fragment compositions and adjusting device, when use, can conversion load onto in sleeve pipe the nut tightened with needs or unclamp or bolt corresponding turn bar, if need to regulate torque magnitude, available screwdriver unscrews or screws the adjustment screw on clamping device, thereby regulate the chucking power of two shell fragments to Flexible spanner hand lever, the size of the frictional force that namely Flexible spanner hand lever will overcome in the time rotating; Thereby realize the object that regulates torsion, of the present utility model simple in structure, it is also convenient to regulate.

Fig. 2 is the spanner decomposition texture stereogram of the adjustable torsion of the utility model;

Fig. 3 is adjusting device enlarged drawing in the spanner of adjustable torsion shown in Fig. 2.

Detailed description of the invention

With reference to Fig. 1, Fig. 2, shown in Fig. 3: design a kind of spanner of adjustable torsion, be provided with Flexible spanner hand lever 6, on the body of rod of described Flexible spanner hand lever 6, interval is shaped with many longitudinal sour jujube bars 61, is separately provided with a clamping device 4, and clamping device 4 comprises two shell fragments that are oppositely arranged 44, 45, two shell fragments 44, 45 two ends are by hold-down screw 9, 12 are fixed together, two shell fragments 44, outwards arch upward respectively and form a holding tank 13 in 45 stage casing, at two shell fragments 44 near one of them hold-down screw 12, on 45 body, be arranged with the clamp groove 41 matching with sour jujube bar 61, 43, one end of Flexible spanner hand lever 6 is sandwiched in two shell fragments 44, 45 groove 41, in 43, at another hold-down screw 9 and groove 41, in two elastic sheet body between 43, be also provided with the adjustment screw 10 for regulating chucking power size, on the body of a shell fragment 44, also punching has one can be against the non-return fastener 42 on sour jujube bar 61 on described Flexible spanner hand lever therein, makes the Flexible spanner hand lever 6 can only one-directional rotation.

In the spanner of above-mentioned adjustable torsion, be also provided with upper cover 3 and lower cover 3 that clamping device 4 is encased, between upper and lower cover 3,2, connect by multiple screws 11, the lower limb of upper and lower cover is provided with the combination bore 201 of stretching out for Flexible spanner hand lever 6.

In the spanner of above-mentioned adjustable torsion, be also set with shell 1 in the outside of upper cover 3 and lower cover 2, on shell 1, have the through hole 11 corresponding with adjustment screw 10 positions, available screwdriver puts in hole adjustment screw 10 is regulated.

In the spanner of above-mentioned adjustable torsion, be also provided with a conversion sleeve pipe 7 that is enclosed within Flexible spanner hand lever 6 external parts, can enter to insert according to the needs of tightening or loosening of large and small different nuts or bolt the wrenching bar of different pore size.

By adjustment screw 10, the torque magnitude of adjustable wrenching bar 6.
