a fixing bracket comprising a base board and a fixing element connected to the base board, wherein the base board defines an opening, and two first slots at a top side and a bottom side of the opening, the fan is mounted to the base board via fasteners extending through the first slots to engage with the fan, with a first side of the fan facing the opening; the fixing element is fixed to the wall of the chassis, therefore the base board is parallel to the PCI card, with a second side of the fan opposite to the first side facing the PCI card, wherein positions of the fasteners in the corresponding first slots are adjustable to adjust a position of the fan.
2. The computer of claim 1, wherein the base board further defines a second slot at an end of the opening and adjacent to the fixing element, allowing screws to extending through one of the first slots and the second slot to engage with the fan, thereby fixing the fan to the base board adjacent to the fixing element.
3. The computer of claim 1, wherein the wall defines two slots under the fixing portion and perpendicular to the motherboard, the second side of the PCI card is attached to one of the slots, and the fixing element covers the other slot.
4. The computer of claim 3, wherein a flange perpendicularly extends from an end of the base board, the fixing element comprises a cover plate covering the corresponding slot of the wall and parallel to the flange, and a tab perpendicularly extending from a top of the cover plate to be fixed to the fixing portion of the wall, the fixing bracket further comprises a connection plate perpendicularly connected between the flange and the cover plate.
5. A fixing bracket for mounting a fan to a wall of a computer, the fixing bracket comprising:
a base board to be mounted to the computer and perpendicular to the wall, the base board defining an opening, and two first slots at opposite sides of the opening, wherein the first slots allow fasteners to extend through to engage with the fan, thereby making the fan face the opening, wherein positions of the fasteners in the corresponding first slots are adjustable to adjust a position of the fan; and
a fixing element attached to the base board and fixed to the wall.
6. The fixing bracket of claim 5, wherein the base board further defines a second slot therein at an end of the opening, adjacent to the fixing element and along a direction perpendicular to the first slots, to fix the fan to the base board adjacent to the fixing element.
7. The fixing bracket of claim 5, further comprising a connection plate, wherein a flange perpendicularly extends from an end of the base board, the fixing element comprises a plate cover to cover the wall and parallel to the flange, the connection plate is perpendicularly connected between the flange and the cover plate.
8. A computer for mounting a fan, the computer comprising:
a wall comprising a fixing portion perpendicularly extending from the wall; and
a fixing bracket comprising a base board to fix the fan, and a fixing element connected to the base board to be mounted to the fixing portion of the wall, wherein the base board defines two parallel first slots, wherein the first slots allow fasteners to extend through to engage with the fan, positions of the fasteners in the corresponding first slots are adjustable, to adjust a position that the fan is located on the base board.
9. The computer of claim 8, wherein the base board defines an opening between the first slots, to align with the fan.
10. The computer of claim 8, wherein the fixing bracket further comprises a connection plate, a flange perpendicularly extends from an end of the base board, the fixing element comprises a cover plate attached to the wall and parallel to the flange, and a tab perpendicularly extending from a top of the cover plate and fixed to the fixing portion of the wall, the connection plate is perpendicularly connected between the flange and the cover plate.
11. The computer of claim 8, wherein a slot is defined in the wall, perpendicular to and below the fixing portion, the cover plate of the fixing element covers the slot.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A driving tool comprising:
a) a housing having an open end;
b) a shaft operably connected to the housing and disposed at least partially within the open end;
c) a gear assembly at least partially disposed within the housing and engaged with the shaft;
d) a gear ratio switching mechanism engaged with the gear assembly; and
e) at least one biasing member configured to continuously urge the gear ratio switching mechanism into engagement with the gear assembly.
2. The driving tool of claim 1 wherein the gear assembly includes a first gear affixed to the shaft, and wherein the gear ratio switching mechanism is urged into engagement with the first gear.
3. The driving tool of claim 2 wherein the first gear includes a central portion having a first width and a number of teeth thereon, and a pair of end sections disposed on opposite side of the end section.
4. The driving tool of claim 3 wherein the gear assembly includes at least one second gear having a second width less than the first width, and wherein the central section of the first gear extends past the at least one second gear.
5. The driving tool of claim 4 wherein the gear ratio switching mechanism includes a locking member including a number of teeth thereon that are engageable with the teeth on the central section.
6. The driving tool of claim 1 wherein the gear ratio switching mechanism includes a locking member engaged with the at least one biasing member and selectively engageable with the gear assembly.
7. The driving tool of claim 6 further comprising a selector ring disposed on the exterior of the housing and secured to the locking member.
8. The driving tool of claim 7 further comprising a cover enclosing the at least one biasing member, wherein the selector ring and the locking member are adjustably engaged with the cover.
