Tool change device

A tool change device, comprising:

• a base, being arranged for enabling the same to move reciprocatingly between a first position and a second position;
• a guiding block, formed with a first engaging part and a second engaging part that are serially connected to each other;
• a lever, formed with a pivot point, a first end and a second end in a manner that the first and the second ends are arranged opposite to each other while allowing the pivot point to be arranged therebetween;
• and
• a spindle, configured with a drive mechanism to be used for connecting the spindle to a tool, being disposed mounting on the base for allowing the same to move in synchronization with the reciprocating movement of the base;
• wherein, the lever is pivotally coupled to the base by the pivot point thereof for enabling the lever to move in synchronization with the reciprocating movement of the base while allowing the opposite first end and the second end to swing about the pivot point in relative to each other;
• and during the moving of the base from the first position to the second position, the lever and the spindle are being driven to move in synchronization with the movement of the base, and thereby enabling the first end to move from the first engaging part to the second engaging part so as to consequently allowing the second engaging part to exert a first force upon the first end while synchronously enabling the second end to exert a second force upon the drive mechanism for driving the drive mechanism to release the tool.
