Description

Nail gun handle fixing device

The present invention relates to a nail gun, and more particularly to a nail gun handle fixing device.

Nail guns are often one of the common hand tools used by decorators. To solve the problem of accidental contact during storage, the manufacturer has developed different fixtures to ensure that the nails can be fixed when the nail guns are not in use. Such as the nail gun disclosed in Taiwan patents M397888, I311516 and 482072.

In the above patent, it can be known that the conventional fixing device is provided with a buckle on the nail gun body, and the fixing method is only to bind the handlebar when the buckle is swung to the vertical horizontal state. However, when the user wants to use the nail gun, it requires two hands to release the handlebar: one hand presses and holds the handlebar, and the other hand controls the buckle to swing backward, which is inconvenient to use.

The other fixing device disclosed in the above patent is that the opponent fixes the action structure corresponding to the inside of the nail gun body, and the entire nail gun structure becomes complicated and numerous components, which leads to an increase in cost and a decrease in production efficiency. And there are many unforeseen failures, and there are shortcomings that need to be improved.

Therefore, how to effectively fix the handlebar, quickly release the handlebar and maintain the structure inside the nail gun body is simple, and it is necessary to provide a novel and progressive nail gun handle fixing device to solve the above problems.

The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Referring to FIG. 1 to FIG. 15, which shows an embodiment of the present invention, the nail gun handle fixing device of the present invention is applied to a nail gun 7, which comprises a body 71 and a handle 72, the handle 72 The nail gun handle fixing device comprises: a hook assembly 1 and a fastener 2.

The hooking component 1 is disposed on the handlebar 72 and is movable along a moving path 5. The hooking component 1 includes a first fastening portion 11 and a pushing unit 16 connected thereto; the fastener 2 is provided for The detachable portion 2 is movably disposed between the release portion and the second release portion 21 and a push unit 25. The first fastening portion 11 and the second fastening portion 21 are releasably fastened to each other when the fastener 2 is in the locking position, and the pushing unit 25 is located in the moving path 5 of the hooking assembly 1 It can be selectively pushed by the pushing unit 16 up. When the hooking component 1 is moved along the moving path 5 When the push unit 25 is moved, the pushing unit 16 pushes the push unit 25 to move the fastener 2 toward the release position to release the first fastening portion 11 from the second fastening portion 21.

As can be seen from the above, the design of the push unit 25 of the fastener 2 is located on the moving path 5 of the pushing unit 16 of the hook assembly 1 so that the user only needs to press the handle 72 to make the fastener 2 The hook component 1 is disengaged, and the handle 72 is released. The user can operate with one hand during the entire release process, which is very convenient and fast, and another vacant hand can be used for holding and pressing other objects.

More specifically, the fastener 2 itself defines a restraining space 24, and when the fastener 2 is in the locked position, the hooking component 1 moves along the moving path 5 through the limiting space 24, In other words, the swing amplitude of the handle 72 is limited to the restricted space 24, thereby achieving the purpose of fixing the handle 72.

More specifically, the first fastening portion 11 includes a base portion 111 and a card portion 112. The base portion 111 is connected to the handlebar 72. The card portion 112 is laterally connected to the base portion 111 to jointly define a fixing slot. The at least one pivot portion 23 of the fastener 2 is rotatably coupled to the body 71 such that the second fastening portion 21 can be selectively swung into the fixing slot 14 and the card portion 112 is moved. The paths 5 are fastened to each other for quick fastening.

In more detail, the two swing arms 22 further include two head portions 222 which are bent toward each other. The two head portions 222 are respectively connected to the two body portions 221, and the moving path 5 further includes the first road portion 51. a second road segment 52; wherein when the hook assembly 1 is moved from the first road segment 51 into the second road segment 52, the two head portions 222 are located on the moving path 5 of the base portion 111, and the base portion 111 is pushed The two heads 222 are urged to push the at least one pivot portion 23 to continue to rotate relative to the body 71.

As can be seen from the above, the pushing unit 16 in the embodiment includes the two connecting portions 13 and the base portion 111. The pushing unit 25 includes the two body portions 221 and the two head portions 222. Moreover, when the handle 72 is pressed to move the hook assembly 1 along the moving path 5, there is a two-stage push: the first stage is The second connecting portion 13 pushes the two body portions 221, and the second portion is that the base portion 111 pushes the two head portions 222, wherein the two head portions 222 are closer to the pivoting point of the fastener 2 and the body 71, The second head portion 222 only needs to be deflected by a small amplitude, and the second fastening portion 21 has a large amplitude yaw. Therefore, when the second stage is pushed, the second fastening portion 21 can quickly cross the card. The portion 112, and thus the first fastening portion 11, is completely released.

Preferably, the side of the card portion 112 facing away from the base portion 111 is an inclined surface 113, and the second fastening portion 21 is selectively slidable along the inclined surface 113. Specifically, when the second fastening portion 21 moves and straddles the inclined surface 113, it includes a locking process or a releasing process, and the inclined surface 113 can assist the second fastening portion 21 to smoothly slide without The situation of the card is dead.

In another preferred embodiment, the nail gun handle fixing device further comprises a positioning component 3 disposed on the body 71. After the second fastening portion 21 is released from the first fastening portion 11, the fastener 2 can be The positioning assembly 3 is selectively positioned in conjunction with each other to stably position the fastener 2. In the embodiment, the positioning component 3 includes two protrusions 31 facing each other and spaced apart, and the two protrusions 31 selectively interfere with the fastening of the fasteners 2.

In another preferred embodiment, the fastener 2 is integrally bent from the rod member, and has a relatively strong structure to fasten the hook assembly 1 and has a long service life.
