The outer shell and the reinforcing sheet are stamped and formed from a special reinforced steel sheet, and the outer shell and the reinforcing sheet are combined and fixed and assembled, and then the punching riveting is used to fix and combine the shape to form the fitting piece. Ontologist. Zhuanzhao and other conventional patent cases are based on two ratchet structures that can be engaged with each other in a locked state or disengaged from the lock state, and the ratchet structure correspondingly arranged between the tooth bar and the clamping block. It can be engaged with each other to be locked at the position of the guard and the trigger of the grab, and the guard and the trigger of the grab can be wrapped and closed to lock it. This type of structure can of course protect the trigger that can't be used for firing, so as to ensure the security that the grab can't be used arbitrarily by a third party. However, the components of the conventional trigger locks in these conventional patent cases are relatively complicated in structure and time-consuming to assemble, so the manufacturing cost is relatively high. In order to respond to the desire of some manufacturers to reduce the purchase cost ', manufacturers are required to reduce the price of their products. Therefore, this creation is based on the concept of reducing manufacturing costs and the premise that the overall function of the trigger lock is not degraded, so part of the structural design is changed. Furthermore, 'in Europe and the United States' some countries are conditionally open to grab weapons' so that private individuals can own or store weapons. Therefore, some collectors who like firearms often have hundreds of weapons collections. Moreover, each gun must be equipped with a pair of locks, so the locks and keys for locking and grabbing branches are also over hundreds of sets; it is very troublesome to use and manage such a large number of locks and keys. Therefore, some collectors of firearms hope that manufacturers can match the combination of locks and keys.

M265589 Fourth, the creation instructions (4) 'a' can be simplified, it is best to control all the locks with only one key, so it will be a great gospel for collectors of weapons grabbing. [New content] In view of this, this creation has been researched and improved to create an improvement of the structure of the lock trigger trigger lock. The main purpose is to change the function of the trigger lock without detracting from the overall function. The corresponding combination of the key and the lock core is designed to make the trigger lock more convenient and simple to use and manage. Another purpose of this creation is to hope to reduce the manufacturing cost and selling price of the trigger lock at the same time by comparing the simplified structural characteristics. In the following, please refer to the drawings to explain the details of this creation in the following preferred embodiments. Please read the first two locks that can be locked with the second insert to make the snap-in parts (1 slot (1 1 card block), and the card block must be a card block.
