Description

446603 C7 D7

The Central Slope Bureau of the Ministry of Economic Affairs, the Consumer Cooperatives, printed the inner rotary seat, which is used to rotate the system, and uses the steel ball and bevel gears to drive the power. It is used for both the rotary type and the cross type. It can be controlled by applying force, and the screw position can be generated by using the rotation position. Once the generated torque is insufficient (the screw may be extremely common; tools, only this kind of work allows users to use it) The magnification is low, and the electrical rate is too fast, and it is very difficult to cause excessive screwing. · This kind of tool is not practical yet. In view of this, the use price of the riveting test for hair products is high; The main screwdriver structure of the case refers to the screwdriver structure that is used to force the external base body to produce a high twisting flange at the state of holding force. The convex umbrella has a screwdriver structure that generates torque transmission stability and lock screws. Those who just hold the handle to fix a word wire to lock or loosen it (a letter-shaped or cross-shaped end is larger than the resistance force of the wire or the screwdriver itself). Therefore, some people have created a work that has a heavy feeling. Part of the acid is due to the control of the screw position of the screwdriver to properly grasp the failure of the screw lock, and how to use it. It can be seen that 1 can be trapped in the grip position or cross shape. Because the position is locally formed, most of it will Deformation caused by heavy electric force is inconvenient to use and operate. Due to the lack of relaxation, the existing handle force and spring teeth and recessed transmission are divided into straight end rods. The force is the strength. The force of the cripple in a situation is likely to cause its rotation. Therefore, please read the note above when you screw up the power.
