The above-mentioned quick connectors have the following common disadvantages:

1. Unable to apply to tool heads of different sizes: Since general tool heads have different shapes (for example: square, hexagonal or round, etc.), and the above-mentioned quick connectors all use steel balls to fix the tool head, Therefore, when encountering tool heads of different shapes, the action of fixing the tool heads cannot be completed, so that the practicability of each quick connector is limited.

2. High manufacturing cost: Because the above-mentioned quick connectors use steel balls to fix the tool heads, it is necessary to process a ring-shaped groove on the outer periphery of each tool head for the steel balls to fasten, so that the tool heads will not fall off. However, processing the annular groove greatly increases the manufacturing cost.

Therefore, it is necessary to improve the aforementioned fast device.
