Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model power tool handle.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated:
As shown in Figure 1, power tool handle 1 has shell 10, and shell 10 is engaged by two portions, and two portions are fixed by multiple screw 16. The top of shell 10 has container cavity 101, and bottom has handguard part 102, and connection portion 103. This connection portion 103 is connected for other parts with power tool. Shell 10 also has upper end open 104 and lower ending opening 105. It is provided with safety buckle 11 in container cavity 101, pulls button 12, pull button spring 13, speed governing knob 14, and control circuit board 15.
The top of safety buckle 11 is exposed to the upper end of container cavity 101 by the upper end open 104 of shell 10. Safety buckle 11 has the first rotating shaft A, and this first rotating shaft A is fixed on shell 10, and safety buckle 11 can rotate around the first rotating shaft A. The bottom of safety buckle 11 is provided with stop 110, and in the present embodiment, safety buckle 11 is roughly in the shape of letter " L ", and this stop 110 down extends, and forms a support arm of safety buckle 11.
The bottom pulling button 12 is exposed to the lower end of container cavity 101 by the lower ending opening 105 of shell 10. Pulling button 12 and have the 2nd rotating shaft B, the 2nd rotating shaft B is fixed on shell 10, and pulling button 12 can rotate around the 2nd rotating shaft B. The top pulling button 12 has protruding 120 and recess 121, and protruding 120 up extend, and this projection 120 is positioned at adjacent position with recess 121. In its natural state, the projection 120 pulling button 12 is positioned at corresponding position with the stop 110 of safety buckle 11. The top pulling button 12 also has actuation portion 122, and this actuation portion 122 also up extends. In the present embodiment, the 2nd rotating shaft B is also positioned at the top pulling button 12, and actuation portion 122 is between the 2nd rotating shaft B and protruding 120.
Pull button spring 13 and there is fixed part and moving part. Fixed part is circle shape, is enclosed within the first rotating shaft A of safety buckle 11; Moving part is strip type, down extends, and with pull button 12 projection 12 to connecing. Pull button spring 13 and there is elastic deformation restorability.
Speed governing knob 14 is also positioned at the top of shell 10, and a part for speed governing knob 14 is exposed to the upper end of container cavity 101, and another part extends to the inside of shell 10. Can move down when speed governing knob 14 rotates simultaneously. In addition, speed governing knob 14 is positioned at than the position of safety buckle 12 closer to connection portion 103.
The container cavity 101 that control circuit board 15 is nested in shell 10 is inner. The upper surface of control circuit board 15 is provided with speed governing circuit and pressure-active element (not shown), and pressure-active element is corresponding with the position of speed governing knob 14, and is also provided with spring between pressure-active element and speed governing knob 14. Regulate the current value size of speed governing circuit by speed governing button 14, thus control the work speed of power tool. The lower surface of control circuit board 15 is also provided with switch circuit (not shown), and switch is positioned at above the actuation portion 122 pulling button 12.
When power tool is in non-working condition, owing to the stop 110 of safety buckle 11 is positioned at corresponding position with the projection 120 pulling button 12, therefore, can prevent from pulling button 12 rotation, thus prevent the actuation portion 122 pulling button 12 from contacting with the switch circuit mistake of control circuit board 15.
When power tool in use, user needs first to press with thumb and rotates safety buckle 11, makes the stop 110 of safety buckle 11 depart from original position, the corresponding position of projection 120 being no longer positioned at pulling button 12; Then also rotate by other finger presses and pull button 12, the recess 121 now pulling button 12 just mates with stop 110 phase of safety buckle 11, pull the restriction that button 12 is no longer subject to stop 120, simultaneously, the actuation portion 122 pulling button 12 contacts with the switch circuit of control circuit board 15 lower surface, and be connected this switch circuit, thus start power tool. In above process, the movable portion pulling button spring 13 receives the effect pulling the projection 120 buckleing 12, and elastic deformation occurs. After user unclamps hand, by pulling the elastic restoring force of button spring 13, make safety buckle 11 and pull button 12 to rotate toward original direction, return to state of nature.
For the power tool handle 1 with said structure, owing to the stop 110 of safety buckle 11 can prevent the mistake rotation pulling button 12, therefore can prevent the situation of mishandle from occurring. That is, user must press safety buckle 11 simultaneously and pull button 12, and power tool could normal start, and avoids the generation of hazardous condition.
Speed governing knob 14 is positioned at the top of shell 10, regulates this speed governing knob 14 when being user-friendly to power tool. And speed governing knob 14 is positioned at than the position of safety buckle 12 closer to connection portion 103, therefore, user, when rotating safety buckle 12, mistake can not touch speed governing button 14.
The above embodiment, just preferred embodiments of the present utility model, it is not limit practical range of the present utility model, therefore all equivalences done according to the structure described in the utility model claim, feature and principle change or modify, and all should be included within the scope of the utility model patent application.
