Abstract
A hand tool includes a handle having a connection end which includes two parallel arms and a driving member has an insertion which is pivotably connected between the two arms by a pin which extends through the two arms and the engaging notch of the insertion. The driving member can be easily replaced by disengaging the pin from the engaging notch of the driving member.

2. The hand tool as claimed in claim 1, wherein a first recess is defined in an inner end of the space between the two arms and a first engaging unit is received in the first recess, the first engaging unit includes a spring and a pawl member which is engaged with a distal end of the insertion of the driving member.
3. The hand tool as claimed in claim 2, wherein the distal end of the insertion includes teeth defined therein and the pawl member is engaged with one of the teeth.
4. The hand tool as claimed in claim 1, wherein a passage is defined in a distal end of the insertion and communicates with the engaging notch, a second engaging unit is received in the passage, the second engaging unit includes a bead, a spring which biases the bead toward the engaging notch and a seal member which seals an opening defined by the passage in the distal end of the insertion, the bead partially protrudes in the engaging notch and is in contact with the pin.
5. The device as claimed in claim 1, wherein a second recess is defined in an inside of the engaging notch and communicates with the engaging notch, the second recess is located remote to a distal end of the insertion and a second engaging unit is received in the second recess, the second engaging unit includes a bead and a spring which biases the bead toward the engaging notch, the bead partially protrudes in the engaging notch and is in contact with the pin, a stop extends inward from an inner periphery of the second recess so as to stop the bead from disengaging from the second recess.
6. The hand tool as claimed in claim 1, wherein a first groove is defined in an inner periphery of the engaging notch and a resilient clamp is engaged with the first groove, the pin includes a second groove with which the resilient clamp is engaged.
7. The hand tool as claimed in claim 6, wherein two blocks extend from the inner periphery of the engaging notch and are located at two ends of the first groove, the resilient clamp includes two distal ends which are engaged with the two blocks when the resilient clamp is engaged with the first groove.
8. A hand tool comprising:
a handle having a connection end which includes two parallel arms and a space defined between the two arms, each arm having an engaging notch defined in an underside thereof;
a driving member having an insertion which is located in the space between the two arms and including a through hole, and a pin engaged with the two engaging notches and extending through the through hole in the insertion, wherein the engaging notch having an open end formed on the bottom of the arm of the handle for engaging/disengaging the handle with/from the driving member, such that the driving member is replaced easily.
a handle having a connection end which includes two parallel arms and a space defined between the two arms, each arm having an engaging notch defined in an underside thereof;
a driving member having an insertion which is located in the space between the two arms and including a through hole, and a pin engaged with the two engaging notches and extending through the through hole in the insertion, wherein the engaging notch having an open end formed on the bottom of the arm of the handle for engaging/disengaging the handle with/from the driving member, such that the driving member is replaced easily.
9. The hand tool as claimed in claim 8, wherein a first recess is defined in an inner end of the space between the two arms and a first engaging unit is received in the first recess, the first engaging unit includes a spring and a pawl member which is engaged with a distal end of the insertion of the driving member.
10. The hand tool as claimed in claim 9, wherein the distal end of the insertion includes teeth defined therein and the pawl member is engaged with one of the teeth.
