Abstract
The utility model relates to an automatic homing mechanism of a pencil sharpener. The automatic homing mechanism of the pencil sharpener comprises an elastic arm which is arranged on a pencil sharpener outer shell, the rear end of the elastic arm extends into the pencil sharpener outer shell, and inner threads are arranged on the inner wall of the pencil sharpener outer wall. A push rod is arranged in the pencil sharpener outer shell, outer threads are arranged on the outer wall of the push rod, the front end of the push rod is provided with a pencil sharpener, and the rear end of the push rod is connected with a transmission shaft. A material storing groove is further arranged in the pencil sharpener outer shell, the front end of the pencil sharpener is arranged in the material storing groove, a reset spring is arranged in the material storing groove, and the front end of the reset spring is abutted against the inner wall of the front end of the material storing groove. According to the automatic homing mechanism of the pencil sharpener, elastic force can be stored by the reset spring, when sharpening is finished, the elastic arm loosens, the reset spring rebounds, each mechanism returns to original state, and special operations are not needed. The automatic homing mechanism of the pencil sharpener moves when in use, and resets automatically after used, and therefore the automatic homing mechanism of the pencil sharpener is convenient to use.
Description
Technical field
The utility model relates to the penknife technical field, refers to especially the automatic homing mechanism in a kind of penknife.
Background technology
When cutting pencil, after once cutting was finished, the part parts were in extreme position, to cut action next time and carried out smoothly in order to make, and needed each parts of penknife are revert to original state.Traditional penknife adopts the spring propulsive mechanism, during use, need manually panel to be pulled out, in the use procedure, panel is gradually playback under the drive of spring, behind the pencil to be removed, panel playbacks fully, panel is pulled out when cutting, this spring propulsive mechanism needs manually to pull open parts at every turn when cutting next time again, in use gradually playback.
The utility model content
Technical problem to be solved in the utility model is: a kind of automatic homing mechanism in can the penknife of automatic homing is provided.
For addressing the above problem, the technical solution adopted in the utility model is: the automatic homing mechanism in the penknife, comprise the elastic arm that is arranged on the penknife shell, the penknife enclosure is stretched in the rear end of elastic arm, and its inwall is provided with internal thread, and the penknife enclosure is provided with push rod, the outer wall of push rod is provided with external screw thread, external screw thread is meshed with internal thread, and the front end of push rod is provided with pencil sharpener, and the rear end of push rod is connected with rotating power transmission shaft; The penknife enclosure also is provided with stock chest, and the front end of pencil sharpener is arranged in stock chest, is provided with back-moving spring in the stock chest, and the front end of back-moving spring and the front inner wall of stock chest are inconsistent, and the front end of its rear end and pencil sharpener is inconsistent.
Be provided with connector on the elastic arm front inner wall, be provided with the slot that matches with connector on the penknife shell, connector is arranged in slot lower end port.
The beneficial effects of the utility model are: the automatic homing mechanism in the above-mentioned penknife utilizes spring to store elastic force, when cut finish after, unclamp elastic arm, recoil of spring, original state is got back to by each mechanism, and this playback mechanism need not special operation, move during use, automatic homing after using, more convenient.
Description of drawings
Fig. 1 is the automatic homing structural scheme of mechanism in the penknife.
Among the figure: 1, elastic arm, 2, internal thread, 3, push rod, 4, external screw thread, 5, pencil sharpener, 6, power transmission shaft, 7, stock chest, 8, back-moving spring, 9, connector, 10, slot.
The specific embodiment
Below by specific embodiment the automatic homing mechanism in the utility model penknife is described in further detail.
As shown in Figure 1, automatic homing mechanism in the penknife, comprise the elastic arm 1 that is arranged on the penknife shell, the penknife enclosure is stretched in the rear end of elastic arm 1, and its inwall is provided with internal thread 2, and the penknife enclosure is provided with push rod 3, the outer wall of push rod 3 is provided with external screw thread 4, external screw thread 4 is meshed with internal thread 2, and the front end of push rod 3 is provided with pencil sharpener 5, and the rear end of push rod 3 is connected with rotating power transmission shaft 6; The penknife enclosure also is provided with stock chest 7, and the front end of pencil sharpener 5 is arranged in stock chest 7, is provided with back-moving spring 8 in the stock chest 7, and the front inner wall of the front end of back-moving spring 8 and stock chest 7 is inconsistent, and the front end of its rear end and pencil sharpener 5 is inconsistent.
Be provided with connector 9 on elastic arm 1 front inner wall, be provided with the slot 10 that matches with connector 9 on the penknife shell, connector 9 is arranged in slot 10 lower end ports.
When pressing elastic arm 1, elastic arm moves on 1 rear end, connector 9 on its front inner wall inserts in the slot 10, the internal thread 2 that is arranged on the elastic arm 1 rear end inwall is fitted with the external screw thread 4 on the push rod 3, when power transmission shaft 6 rotates, push rod 4 helical forms move forward, and promote pencil sharpener 5 helical forms and move forward the back-moving spring 8 that compresses in the stock chest 7; When pencil sharpener 5 can't rotate, pencil sharper cut into, and the back-moving spring 8 in the stock chest 7 is compressed to the limit, unclamp elastic arm 1 this moment, so that elastic arm 1 rear end moves down, push rod 3 loses constraint, under the elastic force effect of the back-moving spring 8 in stock chest 7, each parts resilience playback.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
