an external thread is formed on an outer wall of the stressing element, and an internal thread adapted to the external thread on the stressing element is formed on an inner wall of the housing.
2. The piercing device according to claim 1 , wherein a width of the first recess is larger than or equivalent to a width of the second recess.
3. The piercing device according to claim 1 , wherein an external thread is formed on an outer wall of the housing, while an internal thread adapted to the external thread on the outer wall the housing is formed on an inner wall of the gas bottle holder.
4. The piercing device according to claim 1 , wherein a sealing ring is provided on an outer wall of the housing and configured for indicating a position of the housing; the piercing device is firmly secured to the gas bottle holder.
5. A magazine, comprising:
a gas bottle, having a sealing membrane sealed at a mouth thereof;
a gas bottle holder, configured for holding the gas bottle; and
a piercing device, including:
a housing movable with respect to a gas bottle holder having a gas bottle held therein;
a piercing element received in the housing and configured for piercing into a sealing membrane of the gas bottle; and
a stressing element, received in the housing; the piercing element being fixed on one end of the stressing element that is close to the gas bottle; the stressing element being synchronously rotatable along with the housing for being inserted into the gas bottle, or individually rotatable and movable with respect to the housing for pushing the piercing element to pierce into the sealing membrane or releasing gas inside the gas bottle;
wherein a first recess is lied across one end of the housing that is away from the gas bottle, and a second recess is lied across one end of the stressing element that is away from the gas bottle; the second recess is capable of aligning with or misaligning with the first recess; when the stressing element is rotated to make the second recess align with the first recess, a semi-open channel with an open mouth facing away from the gas bottle is formed;
an external thread is formed on an outer wall of the stressing element, and an internal thread adapted to the external thread on the stressing element is formed on an inner wall of the housing.
6. The magazine according to claim 5 , wherein a sealing ring is provided on an outer wall of the housing and configured for indicating a position of the housing; the piercing device is firmly secured to the gas bottle holder.
7. The magazine according to claim 5 , wherein a first stopping portion is formed on an inner wall of an holding casing, and a second stopping portion adapted to the first stopping portion is provided at one end of the housing that is close to the gas bottle.
8. A pistol, comprising a magazine which includes:
a gas bottle, having a sealing membrane sealed at a mouth thereof;
a gas bottle holder, configured for holding the gas bottle; and
a piercing device, including:
a housing movable with respect to the gas bottle holder having the gas bottle held therein;
a stressing element, synchronously rotatable along with the housing, or individually rotatable and movable with respect to the housing;
a piercing element received in the housing and fixed on one end of the stressing element that is close to the gas bottle; the piercing element is configured for piercing into a sealing membrane of the gas bottle;
wherein a first recess is lied across one end of the housing that is away from the gas bottle, and a second recess is lied across one end of the stressing element that is away from the gas bottle; the second recess is capable of aligning with or misaligning with the first recess; when the stressing element is rotated to make the second recess align with the first recess, a semi-open channel with an open mouth facing away from the gas bottle is formed;
