The difference between Hexagonal and 12 angular

• The difference between Hexagonal and 12 angular
  points on the socket
• 1. Timing
• The hexagonal is traditional shape, but the 12
  angular is later than Hexagonal .
• 2.Function
• The angle of 12 angular are the double angles of
  hexagonal. When you used the wrench to put into
  screw, the hexagonal wrench needs 60 angle, but
  12 angular wrench needs 30 angle. (As figure)
• 3.Size
• The functions and size of the 12 points type is
  the same with the 6 points type and its inner
  part is serrate. It can be fitted with the
  screws head or bolts more closely, its shape
  looks like plum blossom, so it also known as plum
  blossom type.

The red frame is hexagonal and the black frame
is 12 angular.
5
What is the function of the wrenchs angle? 0
,15 ,45 , 75

• To choose various angle wrenches is mainly based
  on using places or the depth of the screws in the
  machines.
• Description
• If the users used the tool non-smoothly, it might
  be caused the space limited or machines location
  problem. In order to use the tools conveniently,
  we design various angle wrenches when we produced
  them.

6
The 0 or 15 of Wrench is suitable for
disassembling the screws without depth.
If there is a little depth for its screws, the
user cant use with 15 wrench.
The user may need to choose its angle of wrench
according to hows depth of its screws.

What is the difference of the teeth application
for ratchet ?

• Due to the different number of teeth, the main
  difference is the angle of rotation. The circle
  is 360 degrees. When the numbers of teeth is
  bigger, each tooth is assigned to the smaller
  angle. (As figure)
• For example,
• When the head of ratchet is 72 teeth, the angle
  of each tooth is 5. In other hand, when the head
  of ratchet is 24 teeth, the angle of each tooth
  will be 15.

8
Advantages and disadvantages

• The users set ratchet into screw or socket when
  they used it.
• They usually turn the body of ratchet to use it.
• If the angle of teeth is smaller, then you can
  use less force on turning its angle. When repair
  technician fixed the car in a narrow place, he
  cant use bigger turning angle.
• However, the advantage of ratchet head has less
  teeth
• The structure of driver and pawl contradict each
  other. (As Figure)
• The teeth are lesser, so the structure is more
  stronger.

The types of Bit/Bit socket

• The using ends divide into 8 type
• PHILLIPS
• SLOTTED
• POZIDRIV
• HEXAGON
• TORX
• TORX
• -TAMPER RESISTANT

The ratchet of Quick-release

• The ratchet has two using functions that divide
  into PUSH and NO PUSH.( As figure)

11
The sockets add the friction with handle and
ratchet when setting sockets doesnt shake, so
they process bead groove in the square hole. The
bead groove of sockets gets stuck the bead of
connector. The PUSH and NO PUSH buttons of
ratchet are designed for the bead groove.
12
PUSH function

• The ratchet has direction button which controls
  the clockwise and counterclockwise and circle
  button which uses to set or disassemble sockets.
  These are two functions
• 1. The steel ball will sink when you press the
  circle button, so it can reduce the resistance to
  set the socket.
  
• 2. The socket cant be taken off if you dont
  press the circle button, so it can prevent the
  socket falling and causing an accident.

(Picture 1) The steel ball will sink when you
press the circle button.
13
(Picture 2) It is convenient to set the socket.
The socket cant set into the ratchet when you
dont press the button.
(Picture 3) When you dont press the button, you
cant take off socket from the ratchet. (When
working on the high altitude, it can prevent from
socket dropping and causing danger.)

The simple description of tools classification

• According to its power sourcing , there are two
  different kind of tools.

Driving force Products category Difference Difference Difference
Driving force Products category Torque Speed Price
Human force Hand Tools Small Slow Cheap
Mechanical force Pneumatic Tools Big Quick A little expensive
Mechanical force Electrical Tools Middle Quick Expensive
Mechanical force Hydraulic Tools More big Slow Expensive
