    摘要: A crossbow includes a magazine mounted to the top of the barrel of the crossbow and located above the flight groove of the crossbow. A storage space is formed through the magazine so as to accommodate multiple arrows therein. A retainer is located in the storage space, and resiliently normally presses the arrows in the storage space so that the users shoots the arrows one by one. The retainer is a resilient and an elongate part, an elongate plate cooperated with a spring, or a block cooperated with multiple springs. The retainer can be pulled or pivoted upward to allow the arrows to be fed into the storage space.

    摘要: A crossbow includes a barrel having a flight section and a head. The head includes a main part and two extensions extending laterally from the main part. The main part is detachably connected to the flight section. Two cam units each include two first limb connected to the two extensions, and two cams. Two second limbs each are a curved limb and have a first end and a second end. The two first ends of the two second limbs are respectively and directly connected to two sides of the flight section or the head. A first string is wrapped around and connected between the two cams. Two second strings are connected between the cams and the second end of the second limbs. The weight center of the crossbow is located close to the user's body and is benefit for operating the crossbow with high balance and accuracy.

    摘要: A simulation laser training cartridge for dry-firing practice adapts to the wear condition of a given firearm and provides a convenient way of measuring the barrel erosion. The cartridge uses multiple adjustable interfacing parts that can be applied selectively and independently according to the condition of the barrel to ensure a snug fit in 3-dimensions. In a 2-unit kit embodiment of the invention, the muzzle unit can work with multiple chamber units for a multi-chamber firearm. The cartridge also includes internal modules for laser property management, status monitoring, movement tracking, memory, and communication to help a user manage the device and allow for advanced training applications. By changing the laser property, the laser training cartridge can work as a bore sight. The cartridge may further include a means to attach an external part, so the external part comprises a means to distinguish a longitudinal position inside said barrel.

    摘要: A crossbow includes a barrel with a flight groove, and a bow. A magazine is mounted to the body and located above the flight groove. A passage is defined through the magazine for accommodating multiple arrows therein. A slot is formed between the magazine and the flight groove. A string of the bow movably extends through the slot. An arm is pivotably located in the passage and includes a hook end which normally presses on a top-most arrow of the arrows in the magazine. When no arrow is in the magazine, the hook end is inserted into the slot and the user cannot successfully cock the string because the string is stopped by the hook end, so that the user is acknowledged that there is no arrow in the magazine.

    摘要: The present invention discloses an integrated force sensor, characterized in comprising: a substrate, flexible through-cavities formed on the substrate, and a flexible skin covering the flexible through-cavities, wherein a lug boss is formed on the substrate; the flexible through-cavities are divided into two segments under the action of the lug boss, one end of the flexible through-cavities is connected with a pressure sensor used to measure the internal pressure of the flexible through-cavities, and the other end of the flexible through-cavities is communicated with outside air. In the invention, the force to be measured changes the gas pressure by changing the shape of an object and detects the magnitude of the force to be measured by detecting the gas pressure. Besides, the overloaded pressure can be released through the pressure release mechanism, without affecting the safety of the film of the pressure sensor or resulting in permanent damage to film.
