Technical Field

The invention relates to an adjustable wrench, in particular to an adjustable wrench convenient to adjust.

Background

The adjustable spanner on the current market uses the turbine of installing on the spanner worm to adjust the size of board mouth, stirs the turbine through the finger during use and drives the size that the activity board lip adjusted the board mouth. The adjustable wrench has the problems that the thread on the surface of the turbine becomes smooth due to the overlong use time of the adjustable wrench, or the friction factor of the contact position of the turbine and the hand is reduced due to the fact that the hand of a user is contacted with engine oil, water and the like, so that the torque is insufficient when the size of the plate opening of the adjustable wrench is adjusted by rotating the turbine, and great inconvenience is brought to the user for adjusting the wrench. In addition, the surface between the turbine and the movable plate lip becomes smooth due to the long-term polishing effect, the friction coefficient is not enough, and the nut is easy to slip when the nut requiring large torque is pulled.

Disclosure of Invention

The purpose of the invention is as follows: the invention provides a monkey wrench convenient to adjust, and solves the problems that the existing wrench has smooth threads on the surface of a turbine due to long service time, the surface of the turbine becomes smooth due to long-term polishing effect between the turbine and a movable plate lip, the friction factor is reduced, so that when the monkey wrench is used for adjusting the size of a plate opening, the friction force is insufficient, and a nut requiring large torque is easy to slip when the nut is pulled, and meanwhile, the problem that when a hand of a user contacts engine oil, water and the like, the friction factor of the contact position of the turbine and the hand is reduced, so that the torque is insufficient when the worm wheel is rotated to adjust the size of the movable wrench plate opening is solved.

The technical scheme is as follows: the adjustable wrench convenient to adjust comprises a handle, a first plate lip, a second plate lip and a worm for adjusting the distance between the plate lips, wherein the worm penetrates through the first plate lip and the second plate lip, the first plate lip and the handle are fixedly connected or are in an integral structure, a fixing mechanism is arranged on the first plate lip, the worm can be fixed by the fixing mechanism, a nut is arranged at one end of the worm, and a clamping pin is arranged on the nut.

Furthermore, the fixing mechanism is a fixing pin, and a groove matched with the fixing pin is formed in the worm.

Furthermore, a central groove is arranged on the nut, and the clamping pin is hinged in the central groove.

Furthermore, a clamping groove is formed in one side, close to the nut, of the handle, and the clamping pin can be clamped in the clamping groove.

Furthermore, a clamping iron sheet is arranged in the clamping groove.

Further, threads are arranged on the inner sides of the first plate lip and the second plate lip.

Has the advantages that: this adjustable spanner adopts the bayonet lock to rotate the size that the worm adjusted the board mouth, and the bayonet lock has played lever effect, and the size of adjusting the board mouth need not too big hard, overcomes ordinary adjustable spanner simultaneously because the effect of material such as water, machine oil leads to the friction factor to reduce and then lead to the not enough phenomenon of moment of torsion between turbine surface and the hand, very big has made things convenient for the use. Simultaneously when pulling the nut that needs great moment, because the bayonet lock card and then prevent the displacement of worm and activity board lip in the draw-in groove, overcome between the turbine of ordinary spanner and the activity board lip because the phenomenon of skidding of long-term "polishing" effect when pulling the nut that needs great moment, promoted the reliability of spanner.

Detailed Description

As shown in fig. 1 to 4, the present embodiment includes a handle 1, a first plate lip 21 and a second plate lip 22, the first plate lip 21 is fixedly connected with the handle 1 or is an integral structure, the worm 3 is connected with and penetrates through the first plate lip 21 and the second plate lip 22, the external thread of the worm 3 matches with the internal thread of the second plate lip 22, and when the worm 3 rotates clockwise or counterclockwise, the first plate lip 21 and the second plate lip 22 can be driven to approach or separate from each other. The first plate lip 21 is provided with a fixing pin 8, a groove matched with the fixing pin 8 is arranged at the corresponding position of the worm 3, and when the fixing pin 8 is screwed down, the worm 3 can be fixed on the combination body of the handle 1 and the first plate lip 21. One end of the worm 3 is provided with a nut 4, a bayonet 5 is arranged on the nut 4, and the bayonet 5 is used for rotating the worm 3 as a lever, so that the worm 3 is more labor-saving to adjust.

For easier turning, the bayonet 5 is mounted in such a way that a central groove 41 is provided in the nut 4 and the bayonet 5 is hinged in the central groove 41. One side that is close to nut 4 on the handle 1 sets up draw-in groove 6, and bayonet lock 5 can the joint in draw-in groove 6. The bayonet 5, which is rotatable about a connection point in the nut due to the hinged connection, is pulled out when adjusting the wrench as a lever and is rotated back into the bayonet 6 when the adjustment is finished. Simultaneously, the advantage is that the clamping pin 5 is clamped in the clamping groove 6 to prevent the worm 3 from displacing, so that the slipping phenomenon caused by long-term polishing between the turbine of the common wrench and the movable plate lip when the nut requiring larger torque is wrenched is overcome. Other mounting means of the blocking pin 5, such as a peripheral pin hinged to the nut 4, are also possible and fall within the scope of the present patent. In order to further fix the bayonet 5 in the clamping groove 6, a clamping iron sheet 7 can be arranged in the clamping groove 6, and the clamping iron sheet 7 can press the bayonet 5 to better play a role in fixing. In order to facilitate the wrench to drive the screw without slipping, the inner sides of the first and second lips 21 and 22 may be provided with threads 9.

The embodiment can be made of chrome vanadium steel or common carbon steel, and the specification of the embodiment is the same as that of a common adjustable wrench. During the use, adopt to rotate bayonet lock 5 and carry out the regulation of board mouth size, reach required width opening back when the board mouth, screw up fixed pin 8 locking worm, with 5 card of bayonet lock in the chucking iron 7 of draw-in groove 6, then use the spanner.
