Pressing type interesting ball-point pen
The utility model discloses a pressing type interesting ballpoint pen. The ballpoint pen comprises a pen holder, a refill, a pressing assembly, a supporting assembly, a pen cap and a pattern display assembly. The refill is slidably arranged in the penholder and comprises a first state in which the front end extends out of the penholder and a second state in which the front end is located in the penholder. The refill is sleeved with the pressing assembly, and the refill can be switched between the first state and the second state by pressing the rear end of the pressing assembly. The rear end of the pen cap sleeves the supporting assembly, and the front end of the pen cap extends in the axial direction of the pen holder. The supporting assembly at least partially sleeves the rear end of the pressing assembly. The pattern display assembly is arranged between the pen cap and the pen holder, rotationally connected with the pressing assembly and slidably connected with the supporting assembly. When the pressing assembly is pressed to enable the refill to be converted from the second state to the first state, the pattern display assembly rotates around the front end of the pattern display assembly, and the rear end of the display piece gradually extends out of the lower side of the pen cap. Through the arrangement, the ball-point pen is higher in interestingness, and interestingness and pressure can be increased for a user.
