Detailed Description

The wrench for quickly adjusting the head clamp distance according to the present invention will be further described with reference to the accompanying drawings and the specific embodiments.

As shown in fig. 1, 2, 3 and 4, the wrench for quickly adjusting the head clamping distance comprises a wrench head 1 with a torque nut, a handle 2 connected with the wrench head 1, the wrench head 1 comprising an auxiliary wrench 3 and an adjusting device 4, the auxiliary wrench 3 comprising a fixed block 6 and a sliding block 7; the adjusting device 4 comprises a sliding piece 9, a connecting piece 10 fixedly connected with the sliding piece 9 and the sliding piece 7, and tooth grooves 11 engaged with each other are arranged between the connecting piece 10 and the sliding groove of the wrench head 1.

The utility model discloses an operating principle lies in, the utility model discloses mainly realize accelerating the vice clamp of 1 spanner of spanner head through the structure that changes traditional adjusting device 4 apart from size adjustment, reach the quick installation of nut or dismantle. Firstly, judging whether the position of a nut to be installed or disassembled is convenient for a user to hold the handle part 2 to apply force to install or disassemble the nut; then, the angle between the wrench head part 1 and the handle part 2 is adjusted to ensure that the handle part 2 is convenient for a user to rotate by applying force in the plane; finally, through the removal of slide adjusting device 4, realize the quick adjustment to sliding block 7 that adjusting device 4 is connected, improve the efficiency of spanner to the quick installation of nut or dismantlement.

The utility model discloses a quick adjustment head presss from both sides the spanner beneficial effect apart from size does, the utility model discloses a spanner structure can realize the function of installing or dismantling the quick of nut. Because the sliding adjusting mechanism is adopted, the clamping distance of the auxiliary wrench 3 for clamping the nut is changed by the traditional rotary twisting mechanism, and the efficiency is further improved; preventing the possibility of the conditioning apparatus 4 being exposed to air for a long period of time and being prone to rust. General nut is hexagonal prism shape, and vice spanner 3 only need the centre gripping to correspond the parallel surface and just can rotate hexagonal prism's nut structure, and traditional spanner head 1's adjusting device 4 is sometimes for quick installation or dismantlement nut, and 3 centre gripping distances of unable regulation vice spanner accord with the size that the nut is fit for completely, the phenomenon of skidding when rotating the nut appears, the utility model discloses because sliding block 7's removal distance adjustability is high, the distance of adjusting the centre gripping nut can be fit for the size of nut completely, has improved the efficiency and the elasticity degree that the nut revolved soon. Connecting piece 10 and wrench head 1's spout is equipped with the tooth's socket 11 of meshing each other, guarantees to twist the in-process of changeing the screw cap, and sliding block 7 leads to the slight relative movement of adjusting device 4 saddle 9 owing to the atress, and then influences the utility model discloses an efficiency and the elasticity degree of nut are perhaps dismantled in the spanner installation.

The face of the wrench head 1 sliding relative to the sliding block 7 is an inclined face. By providing the bevel surface relative to the transverse opposing sliding surface, a greater number of turns or angles of rotation of the nut in the narrow handle portion 2 rotation plane is achieved.

The top end of the sliding block 7 is provided with a stop dog 8. The phenomenon that dog 8 set up the help spanner and prevent skidding at the in-process of twisting the screw cap appears, improves the utility model discloses a 1 efficiency of rotating the nut of spanner head.

The side surface of the tail part of the handle part 2 is provided with a groove 12, a through hole is arranged in the groove 12, the through hole is rotatably connected with a vice 13 through a bolt 14, and the movable part of the vice 13 is connected with the bolt 14. The setting of vice 13 is the use multifunctionality that improves the spanner, sets up vice 13 in the recess 12 of handle portion 2 afterbody simultaneously, and the convenience is when need not to use vice 13, and vice 13 imbeds in handle portion 2 of spanner, does not influence the installation of spanner or the result of use of dismantling the nut.

The side surface of the wrench head 1 is provided with a graduated scale 15. Before the nut is clamped, the size of the nut to be clamped can be compared by the graduated scale 15, the other adjustment for improving the clamping size of the wrench head 1 is realized, and the efficiency of the nut in the screwing process is further improved.

The structure of the sliding block 7, the connecting piece 10 and the engaged toothed groove 11 is similar to the structure relation of the blade connecting structure of the utility knife, and the sliding block 7 fixedly connected with the adjusting device 4 is quickly pushed and positioned by pushing the sliding piece 9. When turning the bolt, it is preferable to press the slider 9 of the adjusting device 4 with a finger in order to prevent the sliding block 7 from moving relative to the fixed block 6, so that the best bolt-turning effect is achieved, and at the same time, the distance between the sliding block 7 and the fixed block 6 is also quickly adjusted, and the action of turning the bolt is also quickly entered.
