The top end of the push rod body 701 is attached to the lower surface of the micro direct current motor 405, the bottom of the push rod body 701 is fixed with a manual push block 713, the center of the manual push block 713 is fixed with a lower lead core clamping barrel 714, the bottom of the lower lead core clamping barrel 714 is in a trumpet shape, the middle and the lower part of the lower lead core clamping barrel 714 are uniformly provided with a plurality of lower grooves 720, the lower grooves 720 divide the middle and the lower part of the lower lead core clamping barrel 714 into a plurality of lower clamping strips 719, the outer part of the lower clamping strips 719 is provided with a guide sleeve 716, the lower clamping strips 719 are inserted into the guide sleeve 716 and can slide up and down along the length direction of the guide sleeve 716, an inner positioning block 717 is fixed below the guide sleeve 716, the inner positioning block 717 is inserted into the positioning hole 504 and matched with the positioning hole 504, a pen tip interface 718 is arranged below the inner positioning block 717, a lower compression spring 715 is arranged on the lower lead core clamping barrel 714 between the inner positioning block 717 and the manual push block, both ends of the lower pressing spring 715 are connected to the manual push block 713 and the inner positioning block 717, respectively.

after the push rod module 7 and the lower inner cylinder body 605 are inserted into the lower outer cylinder body 5, the inner positioning block 717 at the bottom of the push rod module 7 is clamped into the positioning hole 504 in the outer positioning block 502, so that the inner positioning block 717 at the bottom of the push rod module 7 can be positioned through the outer positioning block 502 and the positioning hole 504 on the lower outer cylinder body 5, the inner positioning block 717 and the push rod body 7 are prevented from rotating along the central axis of the lower outer cylinder body 5, and thus, the manual push block 713 can only move up and down and cannot rotate.

When lead needs to be manually discharged or fed, the upper outer cylinder body 2 is repeatedly pressed and loosened, the micro direct current motor 405 in the upper inner cylinder body 3 is driven by the upper outer cylinder body 2 to move up and down along with the upper outer cylinder body 2, while the micro direct current motor 405 moves up and down, the push rod body 701 and the manual push block 713 are further driven to move up and down, the manual push block 713 is used for moving up and down, the manual push block 713 continuously compresses and releases the lower compression spring 715 in the process of moving up and down, when the lower compression spring 715 is released, the guide sleeve 716 is close to the horn-shaped bottom of the lower lead core clamping cylinder 714 to clamp the lower lead core clamping cylinder 714, so that the lead core 702 also moves downwards for a certain distance along with the downward movement of the lower lead clamping cylinder 714, and under the normal condition, the distance of downwards moving every time is 1-3mm, when the lower pressing spring 715 is pressed, since the horn-shaped bottom of the lower lead clamping barrel 714 is far away from the guide sleeve 716, the lower lead clamping barrel 714 releases the lead 702, then the lower pressing spring 715 is released again, the lower lead clamping barrel 714 rapidly moves upwards and resets, after resetting, the lead 702 is clamped again, and along with the downward movement of the lower lead clamping barrel 714, the lead 702 moves downwards for a certain distance under the driving of the lower lead clamping barrel 714, and the process is repeated in such a cycle, so that the lead 702 can be continuously pushed out, and the manual lead discharging of the lead 702 is realized. In fact, the above steps are also the working principle of the existing manual propelling pencil, and will not be described too much here.

In order to freely switch between the electric mode and the manual mode and avoid interference between the electric mechanism and the manual mechanism, the outer wall of the lower inner barrel body 605 is fixed with a mode switching slider 607, the mode switching slider 607 is inserted into the L-shaped sliding groove 503 of the lower outer barrel body 5 and is matched with the L-shaped sliding groove 503, after the whole mechanical assembly of the mechanical, so that the two elastic blocks 505 deform greatly, and the mode conversion sliding block 607 can be removed.

When the mode conversion sliding block 607 is located in the L-shaped sliding groove 503, since the mode conversion sliding block 607 can slide up and down along the longitudinal portion of the L-shaped sliding groove 503, at this time, the upper outer cylinder body 2 is pushed to move up and down, so that the upper inner cylinder body 3, the micro dc motor 405, the lower inner cylinder body 605, the push rod body 701 and the manual push block 713 are driven to move up and down, and the lower outer cylinder body 5 is stationary relative to each moving member, so that manual lead discharging and lead feeding of the lead core 702 can be realized under the pushing of the manual push block 713.

when the mode switching slider 607 is located in the L-shaped sliding groove 503, the worm gear 704 on the slider 703 is far away from the worm 604 and does not engage with the worm 604, so that even if the lead-out button 104 or the lead-in button 105 is pressed, the micro dc motor 405 is started to rotate the worm 604, but since the worm 604 does not engage with the worm gear 704, the position of the slider 703 does not have any relation with the operation of the electric driving member.

In fact, during the manual mode, the upper lead holder 706, the slider 703 and the worm gear 704 move up and down as the lead 702 moves up and down, since the upper lead holder 706 always grips the tip of the lead 702. In the manual mode, the electric mode is in a disabled state.

The upper outer cylinder body 2 is pressed downwards and the upper outer cylinder body 2 is rotated, the upper inner cylinder body 3 also drives the lower inner cylinder body 605 to move downwards and rotate under the driving of the upper outer cylinder body 2, so that the mode conversion sliding block 607 on the lower inner cylinder body 605 enters the lower left part of the L-shaped sliding groove 503, as shown in fig. 22, at this time, the upper inner cylinder body 3 and the micro dc motor 405 compress the push rod body 701, the push rod body 701 compresses the lower compression spring 715 through the manual push block 713, after the lower compression spring 715 is compressed, the lower lead clamping cylinder 714 moves to the lowest part, at this time, since the horn-shaped bottom of the lower lead clamping cylinder 714 is far away from the guide sleeve 716, the space between the lower lead clamping cylinder 714 and the lead 702 is in a loose state, that is, at this time, the lead 702 can freely slide along the lower lead clamping cylinder 714, and lead discharging and feeding of the lead 702 are in an electric mode, the manually actuated member does not have any effect on the movement of the lead 702 and the manual mode is disabled.

When the mode switching slider 607 moves to the lower left end of the L-shaped sliding groove 503, the worm gear 704 of the slider 703 is just engaged with the worm 604.

If the lead discharging button 104 is pressed, the driving shaft 406 of the micro dc motor 405 rotates reversely, the driving gear 407 is driven to rotate reversely while the driving shaft 406 rotates reversely, the driving gear 407 drives the transmission gear 602, the worm shaft 406 and the worm 604 to rotate forward, the worm 604 rotates forward while the worm 604 is meshed with the worm gear teeth 704, so the worm gear teeth 704 and the sliding block 703 are driven to continuously move downward along the sliding cavity 708, and the upper lead clamping cylinder 706 and the lead 702 are driven to move downward while the sliding block 703 moves downward, thereby realizing the electric lead discharging of the lead 702.

Similarly, when the lead feeding button 105 is pressed down, the driving shaft 406 of the micro dc motor 405 rotates forward, the driving gear 407 is driven to rotate forward while the driving shaft 406 rotates forward, the driving gear 407 drives the transmission gear 602, the worm shaft 606 and the worm 604 to rotate backward, the worm 604 drives the worm gear teeth 704 and the sliding block 703 to continuously move upward along the sliding cavity 708 while rotating backward, and finally the sliding block 703 drives the lead clamping cylinder 706 and the lead 702 to move upward, thereby realizing the electric lead feeding of the lead 702.

The electric and manual dual-purpose propelling pencil of the embodiment further comprises a pen point 8 for facilitating writing, and the pen point 8 is fixedly connected to the pen point interface 718.
