Example one

Referring to fig. 1-4, an adjustable ring spanner comprises a spanner sleeve 1 and a handle i 2, wherein an arc-shaped outer wall of the spanner sleeve 1 is fixedly connected with one end of the handle i 2, a quincunx groove 4 is formed in the inner wall of the spanner sleeve 1, a screw hole is formed in the side wall of the spanner sleeve 1, a screw rod 3 is connected to the screw hole in an internal thread manner, and the outer end of the screw rod 3 is fixedly connected with a knob; during operation, the staff overlaps wrench socket 1 on the screw, drives 3 rotatory fit wrench socket's of screw rod plum blossom mold recess 4 to the screw clamp tightly through rotating the knob, and the staff rotates handle 2 again and can realize driving wrench socket 1 pivoted and dismantle or screw up the screw in the time, and the staff of being convenient for installs and dismantles not unidimensional screw according to actual conditions.

One end of the screw rod 3 departing from the knob extends to the inner side of the wrench socket 1 and is fixedly connected with the anti-skid gasket 5; during operation, the anti-slip gasket 5 arranged at one end of the screw rod 3 enhances the clamping effect on the screw, effectively avoids the direct contact between the end part of the screw rod 3 and the surface of the screw, and prevents the screw from being worn by the end part of the screw rod 3 in the rotating process.

A containing groove 7 is formed in one end, away from the wrench socket 1, of the first handle 2, a second handle 6 is connected in the containing groove 7 in a sliding mode, and the first handle 2 is connected with the second handle 6 through a bolt 10; during operation, when the worker can't drive the wrench socket 1 to rotate through the first rotating handle 2, the length of the force arm is increased through the second outward sliding handle 6, so that the worker can mount or dismount the screw more labor-saving.

A plurality of thread grooves 8 are uniformly formed in the end face of the top of the second handle 6, the bottom ends of the thread grooves 8 are conical, a limiting part 9 is embedded in one side, away from the top of the wrench socket 1, of the first handle 2, an elastic limiting component is arranged in an inner cavity of the limiting part 9, the elastic limiting component is connected with a bolt 10, the top of the bolt 10 is connected with the limiting part 9 in a sliding mode, threads are arranged at the bottom of the bolt 10, the bolt 10 is in threaded connection with the thread grooves 8, and the bottom end of the bolt 10 is conical; during operation, when the length of adjustment handle two 6, through pressing down bolt 10 for the toper bottom of bolt 10 constantly with the surface contact of handle two 6 and correspond with thread groove 8, when adjusting to suitable department until handle two 6, through

rotatory bolt

10 and 8 threaded connection of thread groove downwards, make handle two 6 obtain fixedly, make things convenient for the staff to rotate handle two 6.

The elastic limiting assembly comprises a spring 12 fixed at the bottom of the inner cavity of the limiting part 9 and a limiting ring 11 sleeved on the bolt 10, the bottom end of the limiting ring 11 is attached to the spring 12, and the limiting ring 11 is connected with the inner cavity of the limiting part 9 in a sliding manner; during operation, when bolt 10 is rotatory downwards, spacing ring 11 extrudees spring 12, through the spring action of spring 12 and the toper design of bolt 10 bottom for bolt 10 is inseparabler firm with being connected of thread groove 8, and bolt 10 becomes flexible when having avoided rotating handle two 6 effectively and leads to the uneven condition of exerting oneself.

One end of the second handle 6, which is far away from the first handle 2, is provided with a through hole 13; during operation, through the through-hole 13 that is equipped with in the one end of handle two 6 for the staff can drive spanner sleeve 1 rotatory through inserted bar cooperation exogenic action when manual unable turning handle 2 and handle two 6, has improved the practicality of spanner.

Example two

Referring to fig. 5, as another embodiment of the present invention, in a first comparative example, a plurality of first anti-slip strips 14 are uniformly bonded to the top end surface and the bottom end surface of the first handle 2, second anti-slip strips 15 are uniformly bonded to the top and the bottom of the second handle 6, the second anti-slip strips 15 are not overlapped with the thread groove 8, and the first anti-slip strips 14 and the second anti-slip strips 15 are both distributed in an inclined manner; during operation, the staff has the grip one 2 and the handle two 6 frictional force that has greatly strengthened handle one 2 and handle two 6 through bonding grip one 14 and grip two 15 on handle one 2 and handle two 6, has avoided effectively that can't exert oneself when leading to the spanner to use because handle one 2 and handle two 6 are smooth, and the design of grip one 14 and grip two 15 can prevent that the staff palm of the hand from perspiring under the high temperature weather and leading to the inconvenient circumstances of exerting oneself and taking place.

According to the working principle, a worker sleeves a wrench sleeve 1 on a screw, drives the screw 3 to rotate by rotating a knob so as to enable an anti-skid gasket 5 at one end of the screw 3 to be attached to the screw until the screw is clamped tightly, and then rotates a handle I2 so as to drive the wrench sleeve 1 to rotate and simultaneously disassemble or tighten the screw, through the matching between the wrench sleeve 1 and the screw 3, the worker can conveniently adjust the anti-skid gasket 5 according to the screws with different sizes under actual conditions so as to clamp the screws with different sizes, the problem that the worker needs to frequently replace the wrench when encountering the screws with different sizes is avoided, the replacement time is saved, the working efficiency is improved, when the worker cannot drive the wrench sleeve 1 to rotate by rotating the handle I2, through the length of the outside increase arm of force of sliding handle two 6 installation or dismantlement of being convenient for more laborsaving of staff to the screw, when adjustment handle two 6's length, through pressing down bolt 10, make the taper bottom of bolt 10 constantly with handle two 6 surface contact and with thread groove 8 correspond, when adjusting to suitable department until handle two 6, through

rotatory bolt

10 and 8 threaded connection of thread groove downwards, make handle two 6 fixed, make things convenient for staff turning handle two 6, through the elastic action of spring 12 and the toper design of bolt 10 bottom, make bolt 10 inseparable firm with 8 connections of thread groove, bolt 10 becomes flexible when having avoided turning handle two 6 effectively and leads to the uneven condition of having an effect of force.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
