In order to enable your review committee to have a better understanding and recognition of the characteristics and characteristics of this creation, the following preferred examples are listed below with the following description:
Referring to the third and fourth figures, a durable nail gun 100 is provided, which mainly comprises a gun shell 10, a pull shaft 20, a cushion washer 30, and a power. The device 40, a reply device 50 and a control device (not shown), wherein:
Referring to the third and fourth figures, the gun shell 10 is made of aluminum material. The gun shell 10 has a movable chamber 11 and a pull hole 12 connecting the movable chamber 11 to the outside.
Referring to the third and fourth figures, the rivet shaft 20 is integrally formed of steel. The rivet shaft 20 has a force receiving portion 21 and a rivet portion 22 coupled to one end of the force receiving portion 21. And a tail portion 23 connected to the other end of the force receiving portion 21, and the outer diameter of the force receiving portion 21 is larger than the outer diameter of the nail portion 22 and the tail portion 23; the pull shaft 20 is placed on the gun shell 10 Internally, that is, the force receiving portion 21 of the rivet shaft 20 and the tail portion 23 are located in the movable chamber 11, and the rivet portion 22 projects in the spigot hole 12. The rivet shaft 20 is subjected to an external force to perform a linear displacement of reciprocating between a stylus position and a preparatory position.
Referring to the third and fourth figures, the cushioning washer 30 is sleeved on the nail portion 22 of the rivet shaft 20 and attached to the end surface of the force receiving portion 21. The cushion washer 30 is made of aluminum.
Referring to the third and fourth figures, the power unit 40 is coupled to the gun casing 10 for inputting power into the movable chamber 11 to drive the puller shaft 20 to the position of the pull stud.
Referring to the third and fourth figures, the recovery device 50 is disposed in the movable chamber of the gun casing 10 and abuts against the inner wall surface of the movable chamber 10 and the force receiving portion 21 of the pull shaft 20 When the power input from the power unit 40 to the movable chamber 11 disappears, the power of the return device 50 is driven to move the pull shaft 20 to the preparatory position. The recovery device 50 is a spring.
The control device is coupled to the gun casing 10 and can be a control panel for controlling whether the power of the power unit 40 is input into the movable chamber 11.
Therefore, the above description is a description of each component of the durable rivet gun 100 and its assembly manner provided by a preferred embodiment of the present invention, and then its use characteristics are as follows:
When the user deducts the control device and inputs the power of the power device 40 into the movable chamber 11 of the gun casing 10, the rivet shaft 20 is acted upon by the power of the power device 40 to the rivet. The position is displaced (as shown in the third figure) for the spigot job.
When the user releases the control device and the power of the power device 40 disappears, the power of the recovery device 50 drives the pull shaft 20 to move to the preparatory position (as shown in the fourth figure). Since the buffer gasket 30 is attached to the end surface of the force receiving portion 21 of the rivet shaft 20, the rivet shaft 20 and the inner wall surface of the gun casing 10 can be buffered by the buffer gasket 30 to avoid hardening. The rivet shaft 20 has the possibility of damaging the gun casing 10, and the durability and service life of the creation can be improved.
Further, the above-described cushion washer 30 is fixed to the pull stud 20 by a C-shaped buckle 90.
The above description is only for the preferred embodiment provided by the present invention, and is not intended to limit the scope of implementation of the present invention. All of the relevant artisans in the art are equally varied according to the present creation, and should belong to the present invention. The scope of coverage.
