[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-Figure 7 As shown, the utility model discloses a quick-interchangeable screwdriver handle, comprising a handle body 1, a fixed cylinder 2 slidably arranged on the handle body 1, a locking block 3 slidably arranged on the fixed cylinder 2, a dial button 4 slidably arranged on the fixed cylinder 2, a pin 5 slidably arranged on the dial button 4, a working end spring 6 fixedly arranged on the handle body 1 at one end, a dial button spring fixedly arranged on the dial button 4 at one end and fixedly arranged on the fixed cylinder 2 at the other end, and a dial button cover 7 sleeved on the fixed cylinder 2. When in use, insert the rear end of the screwdriver head into the fixed cylinder. As the screwdriver head gradually enters the fixed cylinder, the inclined surface of the locking block contacts the rear end of the screwdriver head, and the locking block is pushed upward. When the locking block moves upward, it will drive the pin to move upward. Since the pin can slide in the long strip-shaped inclined groove on the dial button, the dial button will automatically move forward during the upward movement of the pin. At this time, the dial button compresses the dial button spring, and the dial button spring always provides a rebound force in the opposite direction. As the screwdriver head continues to move backward, the working end spring is compressed. At this time, the working end spring always provides a rebound force in the opposite direction. As the screwdriver head continues to move inward, the edge of the locking block is on the side of the screwdriver head. The toggle button contacts the surface until the groove on the screwdriver head is in the same position as the locking block, the toggle button spring rebounds, driving the toggle button to move backward, thereby driving the pin to move downward, and then driving the locking block to move downward, the locking block enters the groove on the screwdriver head to complete the locking work. When the bit needs to be replaced, the toggle button is pushed forward to drive the pin to move upward, and then drive the locking block to move upward, the locking block disengages from the groove of the screwdriver head to complete the unlocking work. At this time, the spring at the working end rebounds and automatically pops out the screwdriver head, thereby realizing the quick replacement function of the bit. Through such a design, cumbersome operating steps are reduced, time is saved, work efficiency is improved, and the purpose of quick bit replacement is achieved.
