What length of tire wrench is appropriate

Cross tire wrench is flywheel wrench a special tool for tightening or loosening screws. With standard type, different diameter type, positive and negative wire mouth series, 52 types, cross tire wrench can meet the same diameter, different diameter in the horizontal, diagonal, vertical and other positions in the building structure and can adjust the length and direction The need to connect steel bars requires socket wrenches for many car owners and friends to remove car tires or spark plugs. When using a cross tire wrench, you need to adjust the size of the cross tire wrench according to the parts to be tightened, and there must be no gaps. Avoid slipping or damaging parts. In use, the opening line of the cross tire wrench needs to be parallel to the side of the nut. Do not place the cross tire wrench in the six corners and start to twist, which will damage the parts.

Give me a foothold and a long enough lever, I can pry the earth." In the usual research of levers, light levers are mainly used, in simple terms, they do not count levers. It’s own weight, so the longer the lever can be adjusted, the larger the power arm can be to save energy. When considering the weight of the lever itself, the situation has changed. The principle of leverage-----Leverage does not mean that the longer the length is, the more energy is saved. In actual life, it is necessary to choose a cross tire wrench with a suitable length so that it is comfortable to use. Generally, manufacturers will configure four models of seventeen, nineteen, twenty-one, and twenty-two. Some use more flexible design of a square head with a diameter of 12.5 mm at the fourth head position. This drive head can be combined with a sleeve Use, this cross tire wrench has better flexibility when used.

The tire cross wrench selection wrench must not have rust, burrs, cracks and spots; the symmetry of the wrench mouth, the laser lettering must be clear; the hardness must reach the specified standard, and the clamping position must be accurate. The turbine operation of the adjustable wrench should be flexible, and the pin cannot be loose. Working ends with hexagonal holes or twelve corner holes at both ends are suitable for occasions where the working space is narrow and ordinary wrenches cannot be used. According to their different structures, they can be divided into open wrenches, torx wrenches, dual-use wrenches, socket wrenches, hook wrenches, hex wrenches, torque wrenches, and special-purpose wrenches such as percussion wrenches.

If you use a sleeve that is larger than the nut or bolt, the sleeve can easily round the head of the nut or bolt during rotation. When disassembling the tight wheel bolts, if a suitable extension rod is sleeved on the sleeve handle, the rotation torque can be increased, and it is easier to loosen the wheel bolts. It should be noted that if you use a socket wrench handle extension rod when tightening the wheel bolts, remember not to use excessive force to prevent the rotation torque from exceeding the bearing range of the nut or bolt, otherwise the nut or bolt may be easily damaged.
