Detailed Description

The invention is further explained below with reference to the drawings and examples. In the following detailed description, exemplary embodiments of the invention are described by way of illustration only. Needless to say, a person skilled in the art will recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

As shown in fig. 1, 2 and 3, the manual nailing machine comprises a striking guide cylinder 1, wherein a striking rod 2 is slidably mounted in the striking guide cylinder 1, and preferably, the striking rod 2 is a solid rod. The striking rod 2 upwards stretches out the striking guide cylinder 1 is arranged and the top end of the striking rod 2 is fixedly provided with a striking cap 21. The nail installing device is characterized in that a binding space 11 is arranged below the bottom end of the impact rod 2 in the impact guide cylinder 1, a magnetic attraction device 12 is arranged on the upper portion of the binding space 11 on the impact guide cylinder 1, and a lifting force application device 3 and a lifting limiting device 4 are arranged between the impact rod 2 and the impact guide cylinder 1.

In a normal state, the impact rod 2 is kept in a lifting state by the lifting force application device 3, and the lifting position is limited by the lifting limiting device 4, so that the impact rod is prevented from falling out of the impact guide cylinder 1. And the striking rod 2 keeps the space at the lower part of the striking guide cylinder 1 after being lifted, namely the binding space 11. When carrying out nailing fixed work, invert the embodiment earlier, the opening in binding space 11 is up promptly, then packs into fixing pieces 6 such as round pin or steel nail binding space 11, fixing piece 6 fall to under the action of gravity striking rod 2 department, and under the effect of magnetism device 12 of inhaling, with striking rod 2 forms effective actuation, so no matter why the whole gesture of this embodiment, fixing piece 6 is difficult to fall out binding space 11. And placing the lower end of the impact guide cylinder 1 to a position needing nailing for fixing, then hammering the impact cap 21 for multiple times by using tools such as a hammer and the like, wherein the hammering force overcomes the force application of the lifting force application device 3, so that the impact rod 2 continuously impacts the fixing piece 6 downwards. After multiple hammering, the fixing member 6 is driven into the target position to complete the fixing work. At this time, the striking rod 2 is lifted to the initial position and kept under the action of the lifting force application device 3, and the next fixing piece 6 is installed, so that the next nailing and fixing work can be immediately carried out.

In this embodiment, the magnetic attraction device 12 includes a magnetic ring fixedly disposed on the outer peripheral surface of the impact guide cylinder 1. The lifting force application device 3 comprises a lifting force application spring which is sleeved on the impact rod 2 and is positioned between the top surface of the impact guide cylinder 1 and the impact cap 21. The rebound limiting device 4 comprises a rebound limiting pin 41 which is radially and fixedly arranged on the wall of the impact guide cylinder 1, the impact rod 2 is provided with a sliding avoidance long groove 42 corresponding to the inner end of the rebound limiting pin 41, and the bottom end of the sliding avoidance long groove 42 is provided with a rebound limiting step 43. Of course, the lifting limiting device 4 can also be realized by arranging a step on the inner wall of the impact guide cylinder 1 and correspondingly arranging a boss on the impact rod 2.

In this embodiment, a holding sheath 5 is fixedly disposed outside the impact guide cylinder 1, and preferably, the holding sheath 5 is made of a plastic material. The top end of the holding sheath 5 is integrally provided with a holding cap 51, and the holding cap 51 can further improve the safety of preventing the hammer of the hand. For the structure of the lifting limit pin 41 in this embodiment, the holding sheath 5 in this embodiment is correspondingly provided with a limit pin mounting hole 52 and a limit pin through hole 53, the setting of the limit pin mounting hole 52 can keep the holding sheath 5 and the impact guide cylinder 1 in this embodiment fixed, and the limit pin through hole 53 can prevent the lifting limit pin 41 from being exposed. In this embodiment, the rising-back limit pin 41 is a hexagon socket head cap screw, the head of which is located at the limit pin through hole 53, and the rising-back limit pin passes through the limit pin installation hole 52 and is then installed on the impact guide cylinder 1 in a threaded manner.

At least one impact transition body 22 which is gradually reduced in diameter is fixedly arranged between the impact cap 21 and the impact rod 2, and the embodiment shows that the impact transition body 22 is one. The impact transition body 22 can support the impact cap 21, so that the impact cap 21 can form a large hammering stress surface, the occurrence of hammering deflection is reduced, and the safety is further improved.

The setting of this embodiment binding space 11 for it is less influenced by mounting 6 shapes etc. when this embodiment uses, consequently this embodiment can be applicable to the fixed work of multiple round pin or steel nail, and application scope is wide. The fixing piece 6 does not need to be manually held in the whole fixing process, and the hand-hitting event is obviously reduced and the safety is obviously improved through the design of holding the protective cap 51, impacting the transition body 22 and the like. The embodiment has the advantages of simple structure, convenient use and higher popularization value.

The basic principles, main features and advantages of the present invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
