Abstract

The utility model discloses a holding pen which comprises a refill assembly, a shell arranged outside the refill assembly in a sleeving mode and a pressing piece installed on the shell and used for pressing and driving the refill assembly to move downwards. The pressing piece is pressed to push the driving barrel of the refill assembly to move downwards so as to drive the refill spring set to move downwards; the pen further comprises an inner barrel fixed to the shell, an elastic piece with the tail end tilting is arranged at the position, located at the end opening of the inner barrel, of the driving barrel, and when the refill assembly downwards extends out, the tail end of the elastic piece slides out of the inner barrel and abuts against the end face of the inner barrel. The shell is further provided with an unlocking piece used for pressing the elastic piece.

Description

Technical Field

[0001] The utility model relates to a grip pen. Background Art

[0002] Existing grip pens generally rely on the force of your fingers to push down the push-down member to push down the inner barrel and keep the pen core extended. When you release your finger, the pen core returns to its original position under the action of a spring. Therefore, in addition to dealing with the spring force, you also have to deal with the reaction force during writing. This requires your fingers to maintain a firm grip at all times.

[0003] In order to reduce the burden on fingers and avoid using too much force when drawing lightly, we designed a grip pen that can maintain the pen core. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides a grip pen, which aims to solve the problems that the existing grip pen is laborious to use and has a single usage scenario.

[0005] To achieve the above-mentioned object, the technical solution of the present invention is as follows: a grip pen, comprising a refill assembly, a housing that is sleeved over the refill assembly, and a pressing member mounted on the housing for pressing and driving the refill assembly downward; the pressing member is pressed to push the driving cylinder of the refill assembly downward, thereby driving the refill spring assembly downward;

[0006] It also includes an inner cylinder fixed to the outer shell, and the driving cylinder is provided with an elastic piece with a raised tail end at the port of the inner cylinder. When the pen core assembly is extended downward, the tail end of the elastic piece slides out of the inner cylinder and the tail end of the elastic piece presses against the end surface of the inner cylinder; the outer shell is also equipped with an unlocking piece for pressing the elastic piece.

[0007] Preferably, the elastic sheet is integrally connected to the driving cylinder.

[0008] Preferably, the unlocking member is installed between the mounting hole of the shell and the elastic sheet through blocking pieces at both ends and is exposed from the shell.

[0009] Preferably, the shell comprises an upper pen barrel, a lower pen barrel and a pen head, the lower pen barrel is threadedly connected to the pen head, and the lower pen barrel is plugged and fixed to the inner barrel; the upper pen barrel is plugged and fixed to the inner barrel.

[0010] Preferably, the refill assembly is composed of a refill spring group and a drive cylinder, and the rear end of the drive cylinder is closed and sleeved on the refill spring group.

[0011] The beneficial effects of the utility model are: easy and convenient to use, and the burden on the fingers is reduced while being convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Example:

[0020] like Figure 1-7 As shown, a grip pen includes a refill assembly 1, a housing 2 that is sleeved over the refill assembly 1, and a pressing member 3 mounted on the housing 2 for pressing and driving the refill assembly 1 downward; the pressing member 3 is pressed to push the driving cylinder 11 of the refill assembly 1 downward, thereby driving the refill spring assembly 12 downward;

[0021] The housing 2 comprises an upper pen barrel 21, a lower pen barrel 22 and a pen head 23. The lower pen barrel 22 is threadedly connected to the pen head 23, and the lower pen barrel 22 is fixed to the inner barrel by an interference fit. The upper pen barrel 21 is fixed to the inner barrel by an interference fit.

[0022] It also includes an inner cylinder 4 fixed to the outer shell 2. The driving cylinder 11 is located at the end of the inner cylinder 4 and is provided with an elastic piece 5 with a raised tail end. When the refill assembly 1 is extended downward, the tail end of the elastic piece 5 slides out of the inner cylinder 4 and the tail end of the elastic piece 5 presses against the end surface of the inner cylinder 4. The outer shell 2 is also equipped with an unlocking piece 6 for pressing the elastic piece 5.

[0023] The unlocking member 6 is installed between the mounting hole of the housing 2 and the elastic piece 5 through the blocking pieces at both ends and is exposed from the housing 2. The elastic piece 5 is integrally processed and connected with the driving cylinder 11.

[0024] The refill assembly 1 of this embodiment comprises a refill spring assembly 12 and a drive cylinder 11. The rear end of the drive cylinder 11 is sealed and sheathed within the refill spring assembly 12. When the drive cylinder 11 is pressed downward by the pressing member 3 (the drive cylinder 11 is conventional, and its inclined surface is pressed downward), the rear end of the drive cylinder 11 drives the refill spring assembly 12 downward and outward. When the refill spring assembly 12 returns, the spring inside the pen tip completes the return.

[0025] In order to avoid long-term manual squeezing force or to achieve a usage mode without applying force, when the pressing piece 3 is squeezed by hand to extend the pen core assembly 1, the elastic piece 5 on its driving cylinder 11, which was originally inside the inner cylinder 4, moves to the end surface of the inner cylinder 4 and is released and tilted. When the hand is released, the tail end of the elastic piece 5 presses against the end surface of the inner cylinder 4, making it impossible for the pen core spring group 12 and the driving cylinder 11 to return to their original position.

[0026] When it is necessary to retract the refill, the unlocking member 6 is pressed to make the tail end of the elastic piece 5 lower than the end surface of the inner tube 4. Under the action of the refill spring group 12, the entire refill assembly 1 is retracted.

[0027] Compared with the existing grip pen, the utility model increases the design of the inner tube 4 and the elastic sheet 5, so that the grip pen has a locking function, is convenient and easy to use, and reduces the burden on the fingers while being convenient to use.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
