Learn the basic functions of these wrenches
Hammers are also called hammers, and the specifications are also different due to different scopes of use. The hammer heads commonly used in motorcycle maintenance have various round heads and horizontal heads, which can be divided into 0.25 ~ 0.75kg according to weight. Hammer heads made of soft materials such as copper, plastic, rubber and wood are called soft hammer heads. This hammer is used for workpieces that cannot withstand the impact of a steel hammer, such as aluminum alloy parts or thin metal sheets. How to use the hammer and precautions are as follows:
Before working, check whether the hammer head is loose. If it is loose, wedge it with a wedge to prevent the hammer head from flying out and hurting people. The crown sequence reminds that when using the hammer, the sweat and oil stains on the hand and the handle of the hammer should be wiped off, so as to prevent the hammer from slipping from the hand and damaging the object during work. When hitting iron castings, iron pieces or suspension pads with a hammer, do not use too much force, so as not to fly out of the workpiece and hurt people, and please hold the rear end of the hammer handle moderately. When striking, lift the hammer first, look at the workpiece with your eyes, and then strike quickly with your wrist movements so that the hammer surface is flat on the workpiece, so that the hammering will be powerful. A wrench is a tool used to remove and assemble corner nuts or bolts. There are many types of wrenches with different uses. Open-ended wrenches, Torx wrenches, socket wrenches and adjustable wrenches are commonly used in motorcycle maintenance.
There are two types of open-end wrenches: double-ended and single-ended. A set of open-ended wrenches consists of 6 or 8 pieces (6~24mm), used to disassemble and assemble standard nuts or bolts. The opening of the wrench and the wrench body have different angles for easy work in restricted positions. Typical angles are 15°, 45° and 90°, which allows for a more flexible range of angles for the wrench to rotate. The open-end wrench is easy to use, can be inserted up and down or directly, and can withstand high torque.
Wrenches. The use of the torx wrench is the same as that of the open-end wrench, except that the two ends of the torx wrench are socket-type, which is not easy to fall off during work, and is suitable for bolts or nuts with limited disassembly and assembly positions. The inner wall of the sleeve has twelve corners, the sleeve wall is thinner, and the handle is longer. A set of flower pliers, consisting of 6 or 8 pieces (5~27mm).
A dual-purpose wrench, one end is the same as a single-ended wrench, the other end is the same as a torx wrench, and the two ends are screwed with bolts or nuts of the same specification.
A socket wrench, a socket wrench is similar to a Torx wrench. The difference is that the socket part of the socket wrench can be disassembled, and various sockets of different sizes can be assembled when needed. Each set includes 13, 17 or 24 pieces. The casing wrench is suitable for nuts or bolts with small disassembly positions and strong concealment. It can be used in a wide range and improve work efficiency. adjustable wrench. The opening distance of the adjustable wrench can be adjusted arbitrarily within a certain range. Therefore, all nuts, bolts or irregular nuts and bolts within the maximum size range are suitable for a wide range of applications. Adjustable wrenches are sized by their length. There are eight types such as 100, 150, 200, 250, 300, etc.
