The present invention provides a reverse opening type slide fastener in which an upper slider and a lower slider can be held at a bottom end of a box pin when an insert pin is pulled out of the upper slider and the lower slider and separated therefrom. The reverse opening type slide fastener (10) has a separable bottom end stop (22) including a box pin (40) provided consecutively from a bottom end of a right element row (13) disposed on a side edge of a right fastener stringer (17), an insert pin (30) provided consecutively from the bottom end of a left element row (12) disposed on a side edge of a left fastener stringer (16), an upper slider (50) which enables the slide fastener to be opened upward and a lower slider (60) which enables the slide fastener to be opened in a reverse direction. A stopper (46) for preventing the lower slider (60) from slipping off is provided at the bottom end of the box pin (40). A first engaging portion (44) is formed on an opposite side edge opposite to the insert pin (30) of the box pin (40) and a second engaging portion (34) is formed on an opposite side edge opposite to the box pin (40) of the insert pin (30) so as to position the insert pin (30) in a downward direction when the second engaging portion engages the first engaging portion (44). A projecting portion (48) which makes contact with the inner face of the blade of the upper slider (50) so as to suppress a free sliding of the upper slider (50) is formed on at least any one of a front side face and a rear side face opposite to the inner face of the blade of the upper slider (50) of the box pin (40).

The present invention provides a separable fitting (1) in which a box pin (20, 20') has a box pin body (21, 21'), a first cutout (23, 23') for receiving the head end of a locking pawl (36) of a reverse opening slider (30), and a projection (24, 24') projecting toward an insert pin (10) in the direction of the tape width from a surface (26) opposed to the insert pin (10). A side wall surface (23b) of the first cutout (23, 23') and that end surface (24a) of the projection (24, 24') which is provided to the head end side of the box pin are formed flush with each other to form a locking surface (27) with which the head end of the locking pawl (36) makes contact to lock the reverse opening slider (30). The box pin body (21, 21') and the projection (24, 24') have a slope surface (28, 28') declined from the position of the locking surface (27) toward an element row (5). The construction enhances easiness of operation of the reverse opening slider (30) and reliably prevents the reverse opening slider (30) from freely sliding from the box pin-side end of the element row without being slid by human force.

The invention discloses an improved latch needle which comprises a needle head, a needle neck, a needle body and a needle butt, wherein the needle head includes a beard and a latch. On an a side of the latch needle, a pore is arranged on the needle neck in a direction in which the needle neck faces the needle head, the small end of a first spring piece is inserted in the pore, and the other end of the first spring piece is fixed on the needle body. On a b side of the latch needle, an elongated groove is milled in the middle of the needle body, a second spring piece is disposed in the groove, one end of the second spring piece, which faces the needle butt, is inserted in the groove, and the other end of the second spring piece is fixed in the groove. According to the improved latch needle, contact areas between the spring pieces and needle grooves are enlarged, the latch needle is enabled to work in the needle grooves more stably by means of tension of the spring pieces, knitting accuracy is guaranteed, durability of the spring pieces is improved, and the needle butt of the latch needle is not needed to be processed to be arc-shaped any more.

Disclosed are a middle insert (1) for mounting a light decoration strip (2) on a seal (3) of automobile glass, and a glass window containing the middle insert (1), the light decoration strip (2) and the seal (3), wherein the middle insert (1) comprises a first end part (11), a second end part (12), and a connecting part (13) used for connecting the first end part (11) and the second end part (12). The first end part (11) is provided with a first opening (14), the second end part (12) is provided with a second opening (15), and the first opening (14) and the second opening (15) respectively face the outsides of the end parts thereof. The middle insert (1) is simple in structure such that both complexity and labor costs are reduced. By arranging bulges (32) on the seal (3), the clamping intensity of the light decoration strip (2) is enhanced, so that it is guaranteed that the light decoration strip (2) is difficult to loosen, release or remove; and by arranging a binding groove (6) and a binding material (61) or a double-sided tape (5) on the seal (3), the light decoration strip (2) is prevented from freely sliding on the seal (3), thereby guaranteeing the installation accuracy of the light decoration strip (2) at the edge and avoiding abnormal noise.

The present invention relates to the technical field of punch waste treatment, in particular to a punch waste cleaning device, which includes a device housing, a punch body, a punch seat, a chip removal structure, a drive structure, a cleaning structure, a lubrication structure and a collection structure; The chip removal structure can clean the surface of the stamping seat in one direction, avoiding the impact of dust on the stamping, and at the same time, the dust can only be swept away from one side, and the drive structure can make the chip removal structure cooperate with the body of the stamping device to avoid damage to the stamping process Cause interference, through the collection structure, the swept dust can be collected intensively, and at the same time, the collected waste will not accumulate. Through the cleaning structure, the surface of the plate to be processed can be quickly cleaned to avoid impurities on the surface of the plate. Through the lubrication structure After cleaning, the plate can be oiled and lubricated to improve the stamping effect.

The film supply device comprises a conveying mechanism and a film supply mechanism, the film supply mechanism is arranged above the conveying mechanism and used for supplying films to packaging cups on the conveying mechanism, the film supply mechanism comprises a mounting support and a mounting plate used for containing sealing films, and the mounting plate is slidably connected to the mounting support; the mounting plate is provided with a working position for supplying a film to the packaging cup and a film adding position for adding a sealing film to the mounting plate, and the mounting plate transversely slides relative to the mounting support so as to be switched between the working position and the film adding position. The film supply mechanism is arranged to be the mounting bracket and the mounting plate which are in sliding connection, when the sealing film on the mounting plate needs to be supplemented and added, the mounting plate is partially pulled out of the mounting bracket, and an operator only needs to stand on the side part of the film supply device in the whole sealing film adding process, so that the sealing film is completely added. And the body does not need to stretch into a narrow film supply device for adding, so that the operation is more comfortable, and the use experience of an operator is improved.
