Through the knob, the press button and the driving block of the control unit, the control wire is activated to link the engaging member with the engaging teeth to engage with the positioning teeth of the wheel so that the wheel is positioned. The present invention can be operated conveniently.

A multi-folded full-automatic opening-closing umbrella comprises a frame, cloth, a middle rod set, an upper nest, a lower nest, a handle, an umbrella opening / closing transformation ratio mechanism disposed in the middle rod set, and an umbrella opening / closing driving mechanism disposed in the handle and the middle rod set. The umbrella opening / closing driving mechanism drives the middle sleeve of the middle rod set to move up and down relative to the inner sleeve, and linkage opening / closing functions of the sleeves of the middle rod set and the cloth are realized at the same time.

A portable adhesive tape cutting device includes a main body, a cutting unit fixedly on the main body, a handle pivotally connected to two side walls of the main body, and a cover pivotally connected to the handle. The present invention can be used quickly and conveniently for cutting a desired length of adhesive tape. The portable adhesive tape cutting device is provided with the handle for the user to change the position of the portable adhesive tape cutting device conveniently.

A user-friendly jewelry chain having a chain, a charm, a stop ring and a clasp; the stop ring has a flexible positioning component; the charm has a positioning through-hole. The charm is sleeved on the stop ring and fixedly positioned on the stop ring. The clasp has a male end, a female end, a locking sleeve, a flexible pin component and a flat spring component. The female end is connected to the chain; the flexible pin component and the flat spring component are respectively mounted on the female end. A pin slot and a flat spring slot are formed in the locking sleeve. The pin slot has horizontal slots and a vertical slot. The female end is sleeved into the locking sleeve. The flexible pin component and flat spring component of the female end respectively act on slot walls of the vertical slot and the flat spring slot.

The invention discloses a novel arrow tail lamp, comprising an inertial on-off loop formed by the connection of a shell, a low voltage light source and an inertia switch, the inertial on-off loop can be switched between a closed circuit and an open circuit under the function that the inertia switch is functioned by the inertia in a same direction, and an inertial on-off loop formed by the low voltage light source and the power supply through the inertia switch, is arranged in the shell. The novel arrow tail lamp can be started depending on the inertia when the arrow is shot, therefore arrow shooting process is a process of starting the novel arrow tail lamp; furthermore, after the user swings the arrow tail downwards, the disconnection of the on inertial on-off loop can be realized, so that the novel arrow tail lamp is convenient and quick to use.

Automatically stretchable folding spectacles, comprising: a first rim, with a first lens being provided within the first rim; a second rim, with a second lens being provided within the second rim; a first leg; and a second leg, wherein the first rim and the first leg are elastically connected via a first elastic member; the second rim and second leg are elastically connected via a second elastic member; a middle beam mechanism is provided between the first rim and second rim; and a locking mechanism is provided between the first leg and the second leg, which makes the spectacles capable of keeping a folded state after the spectacles are completely folded. The wearer needs only to press the locking mechanism with one hand, and the whole spectacles will stretch naturally and exhibit an available state under the action of the tension of the elastic members.

A full automatic opening and closing straight bone umbrella includes a middle bar set and an opening and closing umbrella drive mechanism in the middle bar set, an umbrella frame, an umbrella cloth, an upper nest, a middle nest, an umbrella handle, and a power source in the umbrella handle. The opening and closing umbrella drive mechanism includes a lead screw connected to the power source and an ejector sleeve driven by the lead screw. The middle bar set includes a middle pipe and an outer pipe. The ejector sleeve passes through the middle pipe and is connected to the outer pipe. When the power source is operated to drive the lead screw to turn clockwise or counterclockwise, the ejector sleeve brings the outer pipe to move up or down relative to the middle pipe to provide a full automatic opening and closing function to the umbrella.

A baby carriage frame has a frame body, a front-seat panel, a rear-seat panel, and two rear-seat fixing assemblies. The two seat panels are mounted on the frame body, and the rear-seat panel is front-and-rear moveable. Two clamping recesses in a bottom of the rear-seat panel are downwardly disposed around the frame body. Each rear-seat fixing assembly has a seat pivot frame and a seat clamping panel pivotally connected to each other, and the seat clamping panel has a seat eccentric part to abut tightly against a transverse side of the rear-seat panel to fix the rear-seat panel on the frame body, which is convenient and quick in use. The clamping recesses on a bottom of the rear-seat panel enable the rear-seat panel to move continuously front-and-rear along the frame body in one step, thereby adjusting the space between the two seat panels to be adapted to various situations.

The present invention provides a multi-layer barrier assembly or device for post-installation injection of a resin, grout, or other fluid. The barrier device comprises first and second layers defining an intermediate open-matrix layer, and at least one injection conduit member in parallel orientation with respect to the first and second layers and having openings for injecting fluid into the intermediate open-matrix layer. The injection conduit may be located between and in parallel orientation with respect to the first and second layers, along an edge of the first and / or second layers, along an outer face of the first layer (if the first layer is a woven or nonwoven fabric), or at any combination of these locations, to enable fluid to be conveyed into the intermediate open-matrix layer. The invention also provides for use of a gel activator within the barrier device cavity, such as pre-installed on open-matrix structure which used for separating the first and second layers of the barrier device, such that a highly flowable injection fluid can be introduced into the device, and its gelation or hardening will be initiated or accelerated by the presence of the gel activator. This will allow for low power grout pumps to be used and facilitate the sealing of fine cracks in the surrounding concrete.
