Abstract: A crossbow trigger device consists of a housing, a trigger lever, a linkage, a sear, a safety lock lever, a safety actuating lever, a safety, a catch, a nock sensor, a sensor lock lever and etc. By assembling the sensor lock lever and the nock sensor, the sear is utilized for limiting the trigger lever, the trigger cannot be triggered under the condition that the safety is independently switched on, or only an arrow is inserted. The safety absolutely cannot be switched on by accidental touching. Under the condition that the trigger wrongly switching on is avoided and no arrow or the arrow is not in right place, the trigger will not fire accidentally. The trigger device is much safer and more reliable.

Abstract: A crossbow is capable of switching between a compound crossbow and a recurve crossbow, comprising a fore unit and a stock. The stock comprises a stock body, and the stock body is provided with a front end. The fore unit is provided with a mounting end; the mounting end of the fore unit is mounted on the front end of the stock body through a connecting bolt, and the mounting end and the front end are of detachable mounting structures. The fore unit is a compound riser unit or a recurve-bow unit, which is assembled with the stock to constitute a compound crossbow or a recurve crossbow. In the invention, the stock can be quickly assembled with and detached from the compound riser unit and the recurve-bow unit to switch the crossbow between the compound crossbow and the recurve crossbow. The users' expenses are reduced, and the operation is more convenient.
