TH7380B - What is the mechanism for inserting and removing the writing rod tip? - Google Patents

Abstract

Mechanisms for the induction and ejection of the shank head can be written through one of the casing heads in and out of the casing. This mechanism consists of one casing No. 1, a casing No. 2, a slit made in a casing No. 1, a clamp No. 3, which is brought in and out through a long slot No. 2, inward and out of casing number 1 can be written on a rod number 4, one of which is inserted into the casing numbered A cam mechanism No. 8 is used in conjunction with clamp No. 3 in such a way that this cam mechanism No. 8 is moved forward and backward in an axial direction. In accordance with the movement of clamp No. 3, which is brought in and taken out. and a spring No. 6 on which the writing rod number 4 has been inclined towards the cam-mechanism by this spring number 6.

Claims (4)

1. The mechanism for the entry and ejection of the shank header is used to write through the outer casing header consists of; The outer casing number (1), the long slot number (2) made into the said outer casing number (1), the clamp number (3), modified to be moved in and taken out of the outer casing number (1), as follows: Say it through a long channel number (2) above; The stem is used to write numbers. (4) which is inserted into the said outer casing number (1); The ball-tooth mechanism No. (8), which has a slope at the fore and at the end of the number (12,14), the actuation part (9,10a), built as a single piece on the clamp number (3), which In conjunction with the aforementioned number (12,14) slope, into the aforementioned cam mechanism number (8) supporting the end of the aforementioned number (4), spring number (6). Which attaches the aforementioned number (4) to the socket; Shoulder barrier number (13) at the inner end of the front slope. For supporting and blocking the aforementioned part number (10a); part used as a pivot point (16) at the inner end. Of the end slope for supporting the end actuation part number (9); By pressing downward on the front of the number (3) clamps, the cam mechanism (8) moves and the numbering rod (4) moves axially forward towards the end of the numbered header. (7) With the aforementioned part (10a) front actuation part, which will be bonded and blocked by the said number (13) barrier and downward pressure on the back of the aforementioned number (3) clamp, Synchronize the triggers at the end of number (9) with the part used as the pivot point (16), which will release the actuation part before the number. (10a) from the aforementioned number (13) shoulder, which allows the said cam mechanism and the said writing rod to be taken out. 2. The mechanism according to claim 1 in which the parts used as a pivot point consist of: The protrusion at the top number (16) at the end of the slope at the end number (14) so that the end spur number (9) is over the impulse. Bend the number (16), when pressure is applied on the end of the number (6) clamp, it expels the actuation part (10a) from the shoulder block (13). 3. Mechanism according to claim 1, whereby the aforementioned actuation mechanism (9) is made by a longitudinal channel in the aforementioned number (3) clamp supporting the slope at the end number (14). Such 4. Mechanism according to claim 1, in which the forward excitation number (10a) consists of the shoulder barrier made on the said clamp. For blocking the clip in the said long slot (2) in the said number (1) sleeve.
