Abstract

The present invention provides a dust-removing structure for the nailer. The dust-removing structure, located at a preset position of the nailer, includes a release valve lever with a control unit for drive. The control unit is a lever-type control unit, having a pivot point, a drive portion and a laterally extended control portion. The drive portion is coupled with the release valve lever, and the control portion swings around the pivot point. An actuating arm is implemented through the control portion and the swinging behavior, making it possible to more easily operate using a single-hand. When the dust-removing structure is assembled at different heights with different shapes of nailers, the operator is only required to replace the lever-type control unit with different lengths to obtain the optimum pressing location.

Claims

1. A dust-removing structure of a nailer, being assembled onto a top cover of said nailer nearby a compressed air chamber of said nailer, said dust-removing structure comprising:

a jet hole, being located at a preset position of said top cover and having an inner end linked to said compressed air chamber;

a hold tank, being located on top cover axial to said jet hole and having a through-hole internally positioned opposite to said jet hole and an assembly port externally shaped onto said hold tank;

a release valve lever, having a braking end and a stress end, said braking end passing through said through-hole of said hold tank, and extending to said jet hole, said stress end passing through said assembly port and placing said release valve lever in an axial slide state, said release valve lever being located securely through a spacing member;

a lever-type control unit, being located externally onto said assembly port of said hold tank, being formed by a plate or post, and comprising a pivot point, a drive portion and a laterally extended control portion, said drive portion being coupled with said stress end of said release valve lever, said control portion being swingable around said pivot point; and

an elastic reset member, being assembled securely in said hold tank, an axial slide of said release valve lever being reset.

2. The structure defined in claim 1, wherein said spacing member comprises a bulge ring and a positioning cylinder, said bulge ring being prefabricated onto a section of said release valve lever corresponding to said hold tank, said positioning cylinder being hollow and having a through-hole for said release valve lever and a stop flange shaped within said through-hole, blocking off said bulge ring, said positioning cylinder having a threaded portion assembled externally thereon, said threaded portion engaging a screwed section set in said assembly port of the hold tank.

3. The structure defined in claim 1, wherein said pivot point of said lever-type control unit is prefabricated onto a middle section of said lever-type control unit and fastened at a fixed point, said drive portion being formed in a curved shape and provided with a through-hole for said stress end of said release valve lever, said stress end having a pin for radial penetration, said control portion being extended laterally to a predefined length away from said drive portion.

4. The structure defined in claim 1, wherein said pivot point and said control portion of said lever-type control unit are separately located at both ends of said lever-type control unit, said pivot point being assembled onto a fixed point of said top cover, said drive portion being assembled onto said middle section of said lever-type control unit, said control portion being pressed and said drive portion shifting inwards to drive said stress end of said release valve lever.

5. The structure defined in claim 1, wherein said control portion of said lever-type control unit is provided with a protruding guide rod, the guide rod having a protruding end extended towards said top cover and a guide groove located opposite to said top cover for insertion and limitation of said protruding end of the guide rod.

6. A control unit of a dust-removing structure of a nailer, said dust-removing structure being located at a preset position on said nailer and being comprised of a release valve lever with a stress end, driving said release valve lever, said control unit comprising:

a lever-type control unit formed by a plate or post and being comprised of a pivot point, a drive portion and a laterally extended control portion, said drive portion being coupled with said stress end of said release valve lever, said control portion being swingable around said pivot point.

7. The control unit defined in claim 6, wherein said pivot point is located on a middle section of said lever-type control unit and fastened at a fixed point, said drive portion having a curved shape and having a through-hole for said stress end of said release valve lever, said stress end having a pin for radial penetration, said control portion is being extended laterally to a predefined length away from said drive portion.

8. The control unit defined in claim 6, wherein said pivot point and said control portion are separately located at both ends of said lever-type control unit, said pivot point being assembled onto a fixed point of said nailer, said drive portion being assembled onto a middle section of said lever-type control unit, said control portion being pressed and said drive portion shifting inwards to drive said stress end of said release valve lever.

9. The control unit defined in claim 6, wherein said control portion is provided with a guide rod, the guide rod having a protruding end extended towards said top cover and a guide groove located opposite to said top cover for insertion and limitation of said protruding end of the guide rod.
