PEN ASSEMBLY PRESS AND LEVER THEREOF

Abstract

A pen assembly press and its lever are disclosed. The lever is installed on either of the pressing mechanisms of the pen assembly press. The lever has a stopping component and particularly a resilient preloading component which consists of a resilient support component between the limiting component and the stopping component, allowing resilient preloading of the stopping component to a certain distance. Therefore, the pen assembly press can achieve greater quickness and accuracy in positioning, smoothness in adjusting operation, and convenience and improvement in using.

DETAILED DESCRIPTION OF THE INVENTION

[0023] FIGS. 1 to 4 show the preferred embodiments of the present invention for the pen assembly press and its lever.

[0024] However, such embodiments are for illustrative purposes only and are the patent application is not subject to the structure.

[0025] Said pen assembly press comprises the following components: abase 10 which is in the form of a long seat extending in an axial direction and comprises a component mounting surface 11; the first pressing mechanism 20 mounted on the component mounting surface 11 of the base 10 adjacent to one of the axial directions, with the first pressing mechanism 20 comprising the first lever 21 and the first operating component 22 controlling the displacement of the first lever 21; the second pressing mechanism 30 mounted on the component mounting surface 11 of the base 10 adjacent to one of the axial directions and spaced apart from the first pressing mechanism 20, with the second pressing mechanism 30 comprising the second lever 31 spaced from the first lever 21 of the first pressing mechanism 20, and both the first lever 21 and lever 31 having a stopping component 315 (note: in this embodiment, it is on the second lever 31); a resilient preloading component 40 installed on either the first lever 21 of the first pressing mechanism 20 or the second lever 31 of the second pressing mechanism 30, with the resilient preloading component 40 consisting of a resilient support component 41 between the limiting component 316 of the second lever 31 (or the first lever 21) and the stopping component 315, allowing resilient preloading of the stopping component 315.

[0026] As is shown in FIG. 2, in this embodiment, the second lever 31 (or the first lever 21) comprises a fixed inner seat 311 and a movable club head 312 harnessed to the periphery of the fixed inner seat 311, with the stopping component 315 installed on one end of the movable club head 312, and a groove 313 (with a stop flange 314 inside) harnessed to the periphery of the fixed inner seat on the other end of the movable club head 312 away from the stopping component 315; the fixed inner seat 311 has a bearing 317 which is loosely engaged with the movable club head 312 and the groove 313. The limiting component 316 is installed on one side of the bearing 317, allowing the resilient top support 41 of the resilient preloading component 40 to be in the form of a coil spring. The resilient preloading component 40 is installed between the stop flange 314 and the limiting component 316. An anti-trip ring 318 is installed at the inner end of the groove 313.

[0027] As is shown in FIGS. 1 and 3, in this embodiment, the first pressing mechanism 20 is a lever-type pressing mechanism comprising a holder 23 for the installation of the first pressing mechanism 20 and the first operating component 22 in the form of a lever moving the first lever 21 of the first pressing mechanism 20 via the interlocking member 24; the second pressing mechanism 30 is a screw-adjusting-type pressing mechanism comprising a fixed seat 36 having a transverse through hole 35 and a threaded rod 37 which is inserted into the transverse through hole 35, so that the second lever 31 and the second operating component 32 are installed at both ends of the threaded rod 37, wherein the second operating component 32 is in the form of a knob controlling the threaded rod 37 in a rotational manner.

[0028] According to said component structure and technical features, the operation of the pen assembly press in the present invention is shown in FIG. 5. When the user fits the pen 50 to be pressed between the lever 21 and the second lever 31, if the pen 50 is only slightly longer than the distance between the lever 21 and the second lever 31, as shown in FIG. 6, only by pushing up the second lever 31 with the resilient support component 41 (as shown by the arrow L1), one can easily clamp the pen 50 between the first lever 21 and the second lever 31. The pen 50 is only inserted and clamped but will not fall easily. Therefore, the user can adjust the pen 50 to the proper horizontal position, and then move the first pressing mechanism 20 to finish the pressing of the pen 50 (that is, press pen body tube and the pen nib tube against each other). The main advantage of the present invention is that the resilient preloading component 40 allows the user to clamp the pen 50 due to the resilient preloading function. It is therefore convenient for the user to move the pen 50 to the proper horizontal position with one hand and operate the first pressing mechanism 20 with the other hand, ensuring more convenient and smooth use and operation of the pen assembly press and more accurate positioning.

[0029] As is shown in FIG. 7, in this embodiment, the second lever 31B (or the first lever 21) comprises a fixed club head 33 having a receiving groove 330 and a movable inner seat 34 in the fixed club head 33. The stopping component 315B is installed at the end of the movable inner seat 34, and the limiting component 316B at the inner wall of the receiving groove 330. The resilient top support 41B of the resilient preloading component 40 is in the form of a coil spring installed between the limiting component 316B and the movable inner seat 34.

[0030] As is shown in FIGS. 9 and 10, at the place where the fixed seat 36 of the second pressing mechanism 30 of screw-adjusting type and the threaded rod 37 join, there is a threaded-rod-type switching component 60 which comprises a columnar block 61 with a handling component 611 at its top for engaging the tooth 62 of the threaded rod 37 and a return spring 63. The fixed seat 36 has a fitting groove 361, on the top of which the columnar block 61 can be installed. The columnar block 61 has a through hole 612 for the threaded rod 37 to be loosely fitted. The through hole 612 is larger than the maximum outer diameter of the threaded rod 37. The tooth 62 is at the bottom of the through hole 612, and the distance from the tooth peak of the tooth 62 to the top wall of the through hole 612 is greater than the maximum outer diameter of the threaded rod 37. The handling component 611 is exposed outside the fixed seat 36. The return spring 63 is installed between the bottom of the columnar block 61 and the bottom wall of the fixed seat 36 to engage columnar block 61 supported by the return coil and the threaded rod 37. When the user presses the columnar block 61 with the handling component 611 (as indicated by the arrow L1), the tooth 62 will be displaced from the threaded rod 37, thereby releasing constituting the threaded rod 37 which can then be pushed and pulled rapidly (as indicated by the arrow L2).
