摘要： A shakable push button pen includes a stopping ring respectively disposed on outer circumferences of front end and rear end of an inner sleeve, a slidable load ring arranged between the two stopping rings, and a shaft extending backwards, assembled with a ratchet on rear end of the inner sleeve. The shaft inserting through an inner hole of a ratchet on the button is threaded with a sliding ring that is slidable inside the inner hole. When the pen is shaken forwards, the inner sleeve and the button are driven to slide forwards by momentum of the load ring that runs into the front stopping so as to make the refill extend or retract. Thus the push button pen can also be used as a shake pen.
摘要翻译： 可摇动按钮笔包括分别设置在内套筒的前端和后端的外圆周上的止动环，设置在两个止动环之间的可滑动的负载环，以及向后延伸的轴，在棘轮的后端组装 内套。 通过按钮上的棘轮的内孔插入的轴线带有可在内孔内滑动的滑环。 当笔被向前摇动时，内套筒和按钮被驱动以通过进入前挡块的负载环的动量向前滑动，以使再充填件延伸或缩回。 因此，按钮笔也可以用作摇笔。

摘要： In a mechanical pencil, a tubular lead reservoir is connected to the rearward end of a lead chuck. A cylindrical weight is fitted slidably around the lead reservoir and is adapted to strike against the chuck to open the same to allow forward feed of the lead when a forward shake is applied to the pen barrel. In order to prevent forward feed of the lead as a result of unintended forward shake while carrying the pencil, a slider disposed rearwardly of the lead reservoir has a radially outwardly extending engagement projection which is adapted to slidably engage either a longitudinal guide slot in the pen barrel or a lateral slot circumferentially and rearwardly extending in the pen barrel. When the engagement projection is in engagement with the lateral slot, the chuck is caused to take an advanced position in which the chuck is open so that a forward stroke cannot feed the lead forward.

摘要： A manual device including a first portion and a second portion. The second portion being at least partially fitted into the first portion and being moveable in translation relative to the first portion. The first portion having a first distal end while the second portion has a second distal end opposite the first distal end. The second portion also includes a locking device designed to prevent the first portion from moving in translation relative to the second portion only when, considered in the direction of gravity. The first distal end is arranged above the second distal end, and the locking device includes a chamber and a ball or equivalent accommodated in the chamber. The chamber is provided only in the second portion.

摘要： An improved writing instrument includes a main casing, a head portion, a relay rod, and a tail stopper. The head portion can be connected to the main casing and is centrally provided with a tip hole for passage of a reservoir tube. The tail stopper can be fitted to the relay rod. A core tube is disposed between the main casing opposite to a rear end of the head portion and the relay rod opposite to the tail stopper. The end of the core tube facing the head portion is provided with a core chamber, whereas the end facing the tail stopper is formed with a core tube hole. The section of the core tube facing the tail stopper has a smaller external diameter, with two or more ball holes symmetrically disposed therein. A core post is inserted in the core tube and has a post ring of a larger external diameter formed at a rear end thereof to serve as a limit. An intermediate portion of the core post is provided with a core groove corresponding to the positioning balls. A movable ring is slidably disposed between the relay rod and the core tube. When the head portion faces down, the core post and the movable ring slide downwardly, and the core post is restricted by the positioning balls and the movable ring. When the head portion faces up, the movable ring and the core post lower and retract.

摘要： The present invention relates to a swing-type mechanical pencil wherein lead can be extended from a head member connected to an outer sleeve by swinging the outer sleeve to move a knocking hammer. The knocking hammer applies a lead-feeding action to feed the lead. A chuck shutting hammer is mounted between a spring bearing of a chuck ring sleeve retaining a chuck ring which is a component of the lead holder and a second spring connected with the chuck. An upward movement of the chuck shutting hammer forces the chuck into a chuck ring. This provides a positive action to shut the chuck preventing slipping of the lead when writing with the mechanical pencil. Manual advance of lead is provided by a slider in a recession an outer surface of the sleeve that engages the lead holder allowing the chuck to be manually opened to extend lead.

摘要： The pen consists of two pen bodies, preferably identical, which interlock with each other in a plurality of longitudinal positions. Each of the pen bodies is preferably provided with a seat for positioning a ball point cartridge therein. Movement of the pen bodies will cause the cartridges seated therein to be protracted or retracted.
