Abstract

A push-type automatic pencil refill supply box device includes an upper cover, a lower cover, a front support base, a return spring, a sliding block, a pushing block, a rear support base and a bottom cover. The device can push the push block by fingers to send the refill stored in the upper cover out of the supply box along the front support base and the lower cover, thereby forming a push-type automatic pencil refill supply box device. In the past, when refilling automatic pencil refills, the refills had to be slid out naturally by tilting the refill storage box. After removing the required refills, put the remaining refills back into the refill storage box. . In this way, not only is it difficult to control the amount of slide-out of the refill, but it is necessary to take the refill by hand and then put it into the automatic pencil refill and put it in the mouth to complete the supplementary action of the automatic pencil refill. In this way, when placing and refilling the refill, not only the fingers will be polluted, but also the refill may be broken and wasted. The device can push the refill stored in the upper cover by pushing the push block with your fingers, and send it out of the supply box along the front support base and the lower cover. It can also be placed in the mouth with the automatic pencil refill without touching it directly in your hand. Under the condition of touching the refill, the supplementary action of the automatic pencil refill is completed, and the above-mentioned problems are solved.

A push-type automatic pencil refill supply box device includes an upper cover, a lower cover, a front support base, a return spring, a sliding block, a pushing block, a rear support base and a bottom cover. The device can push the push block by fingers to send the refill stored in the upper cover out of the supply box along the front support base and the lower cover, thereby forming a push-type automatic pencil refill supply box device. In the past, when refilling automatic pencil refills, the refills had to be slid out naturally by tilting the refill storage box. After removing the required refills, put the remaining refills back into the refill storage box. . In this way, not only is it difficult to control the amount of slide-out of the refill, but it is necessary to take the refill by hand and then put it into the automatic pencil refill and put it in the mouth to complete the supplementary action of the automatic pencil refill. In this way, when placing and refilling the refill, not only the fingers will be polluted, but also the refill may be broken and wasted. The device can push the refill stored in the upper cover by pushing the push block with your fingers, and send it out of the supply box along the front support base and the lower cover.

Under the condition of touching the refill, the supplementary action of the automatic pencil refill is completed, and the above-mentioned problems are solved.

In the past, when refilling automatic pencil refills, the refills had to be slid out naturally by tilting the refill storage box. After removing the required refills, put the remaining refills back into the refill storage box. . This not only makes it difficult to control the amount of slide-out of the refill, but also requires the refill to be held by hand. Put it into the automatic pencil refill and put it in the mouth to complete the supplementary action of the automatic pencil refill. In this way, when placing and refilling the refill, not only the fingers will be polluted, but also the refill may be broken and wasted.

A push-type automatic pencil refill supply box device includes an upper cover, a lower cover, a front support base, a return spring, a sliding block, a pushing block, a rear support base and a bottom cover. The device can push the push block by fingers to send the refill stored in the upper cover out of the supply box along the front support base and the lower cover, thereby forming a push-type automatic pencil refill supply box device. It can also be put into the mouth with the automatic pencil refill, and the supplementary action of the automatic pencil refill can be completed without the hand directly touching the refill, thereby solving the above-mentioned problems.

Please refer to Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, Figure 6, Figure 6, Figure 7, Figure 8, and Figure 9. This creation is a push-type automatic pencil refill supply box The device includes an upper cover (10), a lower cover (15), a front support base (20), a return spring (25), a sliding block (30), a pushing block (35), a rear support base (40) and a bottom cover (45). The device can push the push block (35) by fingers, so that the sliding projection (35A) on it moves forward along the push slot (15B) on the lower cover (15), which will force the slide block (30) ) Also moves forward and slides into the sliding buffer groove (20A) on the front support base (20). The spring placement groove (20C) placed on the front support base (20), and the return spring (25) between the spring placement protrusion (30C) on the sliding block (30) are compressed and shortened. At the same time, the sliding projection (30A) on the sliding block (30) will also slide the refill slide groove (20B) on the front support base (20) and the refill slide on the slide block (30). The refill in the groove (30B) is pushed forward, and is fed out of the supply box through the hole formed by the refill outlet groove (10A) above the upper cover (10) and the refill outlet groove (15A) below the lower cover (15). outer. Therefore, if the automatic pencil refill is put into the mouth, the supplementary action of the automatic pencil refill can be performed without the hand directly touching the refill. When the finger leaves the push block (35), the compressed return spring (25) will automatically push the slide block (30) and the push block (35) back to their original positions to complete the refill operation.
