The pointed-tail ratchet wrench is often produced from high-quality carbon steel forging that has undergone a comprehensive heat treatment process. To prevent human injury brought on by issues with product quality during use, products must pass quality inspection and verification.
YT-4934 Ratchet Wrench
The manufacturing material of the pointed-tail ratchet wrench is generally made of high-quality carbon steel forging and processed through overall heat treatment. Products must pass quality inspection and verification to avoid personal injury caused by product quality problems during use.
The structure of YT-4934 Ratchet Wrench
The ratchet is the main component of the ratchet wrench. A spring forces the pawl and ratchet into contact. Wherein the rocking bar is vacantly sleeved on the ratchet shaft, the ratchet is contained on the rocking bar, and the ratchet is then fixedly connected to the driven shaft with a key.
The working principle of the YT-4934 Ratchet Wrench
When the rocker of the active part swings counterclockwise, the driving pawl is inserted into the tooth groove of the ratchet, and the ratchet is pushed to turn through an angle. At this time, the stop pawl slides on the tooth back of the ratchet. When the rocking bar of the active part swings clockwise, the stop pawl prevents the ratchet from rotating clockwise, but the driving pawl can slide over the tooth back of the ratchet, so the ratchet remains motionless. For this, when the rocking bar is done continuous reciprocating swing, the ratchet just makes a one-way intermittent motion. The reciprocating swing of the active part can be obtained by the cam mechanism of the swing follower, the crank rocker mechanism, or by hydraulic transmission and electromagnetic devices.
The rules for safe use of The structure of YT-4934 Ratchet Wrench
The wrench should be kept level with the plane of the bolt or nut to prevent the wrench from slipping out and hurting people when the force is applied.
Do not add a sleeve to the end of the wrench to extend the moment arm to prevent damage to the wrench.
Do not hit the wrench with a steel hammer. The wrench is easily deformed or damaged under impact load.
It is not allowed to mix metric wrenches with imperial wrenches, so as not to cause slippage and hurt the user.
The application of YT-4934 Ratchet Wrench
It is mainly used in high-altitude operations, scaffolding work on construction sites, air duct construction, piping construction, electric power construction, mechanical maintenance, equipment maintenance, home decoration, auto repair, and other fields.
