2. The tail cover is quickly connected and disassembled, and the firing spring can be conveniently replaced at any time, so that the force of the firing spring can be adjusted and increased at any time, the suspended ceiling nailing device can be used for not only a common integral bullet, but also an integral bullet made of other materials such as a nitrocotton integral bullet, the application range is enlarged, and the application range is wider.
3. Compared with the regulator with the strip-shaped grooves in the prior art, the regulator is not easy to damage under the high temperature and the air pressure of firing, and the problem that the regulator with the strip-shaped grooves is easy to break due to poor stress state is solved, so that the regulator can be continuously used under the condition of no cooling, the service life is longer, and the safety of equipment is higher.
4. The firing pin body can be matched with the tail cover to limit the compression distance of the firing spring, so that the phenomenon that the firing spring is easily damaged and has a short service life in the use process is effectively avoided, and the service life of the firing spring can be more than 5 times of that of the existing spring in the actual use process.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The invention is mainly divided into four major components:
a striker holder assembly: consists of a firing pin seat, a firing pin seat sleeve and a firing pin sleeve, and mainly plays a role of bearing a firing pin.
Firing pin body assembly: consists of a firing pin and a firing pin body.
Firing assembly: the tail body and the firing sleeve are connected through threads to play a role of firing a firing pin.
A jacket assembly: the multifunctional hand-held device consists of an outer sleeve body and a tail cover, and is used for bearing all components in the hand-held device and is also a hand-held part of an operator.
Firing pin body assembly:
the assembly steps of the components of the invention are as follows:
(1) A striker holder assembly: firstly, the safety spring and the safety pin are installed in the safety pin counter bore, then the firing pin body component is installed in the firing pin seat, meanwhile, the firing pin seat sleeve is sleeved and connected, and the guide pin is inserted into the guide groove.
(2) The firing pin seat assembly is arranged in the outer sleeve body, the firing pin seat spring and the firing spring are respectively arranged in the outer sleeve body, the tail cover is covered by the tail cover in a threaded connection mode, the firing sleeve is tightly propped against the firing pin seat by the tail cover, and meanwhile the firing spring and the firing pin seat spring are compressed.
