Hand tools market positioning
Aerospace level It is higher than industrial
level to request products quality with the strict
way.
Industrial level It is higher than professional
level to request higher product quality.
Professional level Its the basic level of
professional hand tools.
DIY level Its for general use.
3
Market place
Market segmentation Major sales channel
DIY level 1. Normal user 2. General family
Professional level 1. Automobile repair factories 2. The maintenance of general machines and equipments 3. The maintenance of agricultural machines
Industrial level 1. Manufacture and assembling line for vehicles 2. Mining industries 3. The petroleum industries 4. The public projects 5. Other industries
Aerospace level 1. Aircraft manufacturing industries 2. Aerospace industries

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.
7
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.

9
The types of Bit/Bit socket
  • The using ends divide into 8 type
  • PHILLIPS
  • SLOTTED
  • POZIDRIV
  • HEXAGON
  • TORX
  • TORX
  • -TAMPER RESISTANT

10
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
