Abstract

A reciprocating tapping device includes a casing, a motor, a power supply, a transmission portion and a tapping portion. The tapping portion is connected with and driven by the transmission portion. An eccentric shaft is connected with the transmission portion. The tapping portion has a reciprocating portion. The reciprocating portion is connected with two tapping bars. The bars extend out of the casing. The eccentric shaft can covert the circular motion of the motor to back-and-forth motion. Therefore, the tapping portion can move backwards and forwards and the two tapping bars can move backwards and forwards. A flat plate is disposed in the front and back of the reciprocating portion so as to pivotally hold the reciprocating portion. Therefore, the tapping portion can move backwards and forwards without any sideway motion.

Claims

1. A reciprocating tapping device, comprising:

a casing;

a motor located in the casing;

a power supply, supplying electricity to the motor;

a transmission portion, driven by the motor; and

a tapping portion, wherein the transmission portion drives the tapping portion to carry out a reciprocating tapping action, and wherein an eccentric shaft is connected with the transmission portion and a reciprocating portion is disposed on the tapping portion, wherein the reciprocating portion is connected with two tapping bars, which extend out of the casing, and wherein the eccentric shaft can convert circular motion of the motor to back-and-forth motion and thus the eccentric shaft can drive the reciprocating portion to move backwards and forwards,

characterized in that a flat plate is disposed in front and back of the reciprocating portion so as to pivotally hold the reciprocating portion, and wherein one end of each plate is pivotally mounted on the casing and the plates can prevent the sideway movement of the reciprocating portion.

2. The reciprocating tapping device as in claim 1, wherein the plates are pivotally connected with the reciprocating portion through pins.

3. The reciprocating tapping device as in claim 1, wherein the plates are pivotally connected with the casing through pins.
