Abstract

Claims (16)

1. A handle connection mechanism comprising:

the handle having a distal end and a proximal end opposite the distal end,

the proximal end comprising a hollow portion;

a connector having an outer lateral surface and a recess therein, the recess forming a cavity within the connector;

a spring-loaded ball-snap element having a ball and a spring configured to apply a radial force onto the ball,

the spring-loaded ball-snap positioned within the cavity of the connector,

wherein the spring applies the force onto the ball in a direction towards the outer lateral surface of the connector;

a head being repeatedly attachable to and detachable from the handle ( 12 ) via the connector;

wherein a portion of the connector having the spring-loaded ball-snap element therein outwardly extends from the proximal end of the handle and the ball slightly extends beyond the outer lateral surface surrounding the ball.

2. The handle connection mechanism of claim 1 , wherein at least a portion of the handle is electroplated.

3. The handle connection mechanism of claim 1 , wherein the proximal end of the handle has an upper surface that is at least partially chamfered, wherein an angle α from about 15° to about 30° is formed between the chamfered upper surface and a cross-sectional area extending substantially perpendicular to the longitudinal axis.

4. The handle connection mechanism of claim 1 , further comprising at least a first substantially cylindrical section, a second substantially cylindrical section, and an at least partially conically shaped section connects the first and second cylindrical sections, wherein the first substantially cylindrical section, the at least partially conically shaped section, and the second substantially cylindrical section are arranged in consecutive order along the longitudinal axis and wherein the first substantially cylindrical section and the second substantially cylindrical section are off-center with respect to the longitudinal axis.

5. The handle connection mechanism of claim 4 , wherein at least one of the first and second substantially cylindrical sections comprises a flattening portion.

6. The handle connection mechanism of claim 5 , the flattening portion is provided with the recess forming the cavity.

7. The handle connection mechanism of claim 5 , wherein the head comprises a distal end and a proximal end opposite to the distal end, and the proximal end comprises a hollow portion for receiving a portion of the connector when the head is attached to the handle, the hollow portion comprises an inner wall, and the inner wall comprises a recess for receiving the ball of the spring-loaded ball-snap element.

8. The handle connection mechanism of claim 7 , wherein the inner wall of the hollow portion comprises two ribs arranged opposite to each other.
