Abstract
A special-shaped wrench comprises a handholding part of which one end is provided with an arc clamping part; one end of the clamping part is fixedly connected with one end of the handholding part while the other end is provided with a clamp block matched with the groove on a round nut; a sharp bump is arranged at the inner arc face, close to one end of the handholding part, of the clamping part; and one end, far away from the clamping part, of the handholding part is provided with a hanging hole. The special-shaped wrench can conveniently screw or unscrew the round nut, and can avoid the damage of the round nut when the round nut is hammered by a hammer.
Description
Technical field:
The utility model relates to a kind of spanner, specifically is a kind of profile spanner be used to pulling round nut.
Background technology:
General and the round nut stop washer of round nut is used in conjunction with, the round nut perisporium is provided with four or six grooves, the round nut stop washer is provided with the tooth that matches with groove, after screwing round nut with instrument, the tooth bending of round nut stop washer is entered in the groove of round nut, round nut namely is locked, when needs dismounting round nut, bending is out in the groove with the tooth of round nut stop washer, unscrew round nut with instrument again, because the shape of round nut is more special, general die nut can't be used for screwing or unscrew round nut, screws at present or unscrews round nut and generally adopt hammer to beat, when hammer beats, screw thread on the round nut easily damages, thereby this round nut is damaged, and can't use.
The utility model content:
The technical problems to be solved in the utility model is the profile spanner that provides a kind of and can screw easily or unscrew round nut, avoids round nut to damage.
Technical solution of the present utility model is, provide a kind of profile spanner with following structure: comprise shank part, one end of shank part is provided with clamping part, wherein, clamping part is circular arc, one end of clamping part is fixedly connected with an end of shank part, and the other end of clamping part is provided with the fixture block that matches with groove on the round nut.
Profile spanner described in the utility model, wherein, clamping part is provided with pointed projection near the inner arc surface of shank part one end.
Profile spanner described in the utility model, wherein, shank part is provided with hanging hole away from an end of clamping part.
After adopting above structure, compared with prior art, the utility model profile spanner has the following advantages: when using this profile spanner, one end of clamping part is propped up round nut, the fixture block of the other end of clamping part is embedded in the groove of round nut, at this moment, the application of force on shank part, this profile spanner is rotated, rotate thereby drive round nut, can make this round nut screw or unscrew, very convenient, need not screw or unscrew round nut by the mode that hammer beats, can avoid the thread damage on the round nut, thereby avoid that round nut is damaged and situation about can't use occurs.
The effect that the inner arc surface of one end of the close shank part of clamping part is provided with pointed projection is: after an end of clamping part was propped up round nut, pointed projection can be pressed on the round nut, can make an end and the round nut of close shank part of clamping part fixing firm.
Hanging hole can be used for hanging this profile spanner, makes things convenient for the placement of this profile spanner.
Description of drawings:
Fig. 1 is the main TV structure schematic diagram of the utility model profile spanner;
Fig. 2 is the structural representation of the utility model profile spanner when pulling round nut.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments the utility model profile spanner is described in further detail:
As depicted in figs. 1 and 2, in this specific embodiment, the utility model profile spanner comprises shank part 2, one end of shank part 2 is provided with clamping part 1, clamping part 1 is circular arc, one end of clamping part 1 is fixedly connected with an end of shank part 2, the other end of clamping part 1 is provided with the fixture block 5 that matches with groove 7 on the round nut 6, clamping part 1 is provided with pointed protruding 4 near the inner arc surface of shank part 2 one ends, shank part 2 is provided with hanging hole 3 away from an end of clamping part 1, and shank part 1 and clamping part 2 are by No. 45 steel, 40 boron steels, the high-strength material manufacturings such as 20 manganese titanium boron steels or 35CrMoA steel alloy form.
The operation principle of the utility model profile spanner is as follows: when using this profile spanner, clamping part 1 is propped up the periphery of round nut 6, fixture block 5 is snapped in the groove 7 of round nut 6, at this moment, the application of force on shank part 2, this profile spanner is rotated, thereby driving round nut 6 rotates, when round nut 6 turns an angle, adjust the position of this profile spanner, fixture block 5 is snapped in another groove 7 of round nut 6, continuation is the application of force on shank part 2, round nut 6 is rotated further, repeats above-mentioned action, can make this round nut 6 screw or unscrew.
Above-described embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
