Specific embodiment

Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.

Referring to Fig.1, Fig. 2, Fig. 3 and Fig. 4.A kind of semi-automatic pull head axially rotated, including single head 1 and pulling-on piece 2, single head 1 Upside is installed with positioning groove seat 3, positions in groove seat 3 and is installed with pin shaft 4, reset spring 5, the rotation of pulling-on piece 2 are arranged on pin shaft 4 End 21 covers at 5 outside of reset spring and is rotatably connected with pin shaft 4；It is equipped with purl 22 on the downside of pulling-on piece 2, is opened up on the upside of single head 1 There is purl hole 11；51 contacted with the turning end 21 of pulling-on piece on the upside of reset spring, downside 52 is contacted with single head 1, enable pulling-on piece 2 Being affixed downwards to merge with 1 upper side of single head under the elastic force effect of the reset spring 5 makes the purl 22 insertion purl hole 11 with complete At self-locking；The pulling-on piece 2 can be flipped up to unlock.The utility model simplifies pull head accessory and structure, and installs After complete, due to 5 pull-tab 2 of reset spring apply elastic force effect so that pulling-on piece have downward pressure, so as to downwards with The fitting of single head upper side, and it is self-locking to complete to allow purl 22 to be inserted into purl hole 11, it will not sliding lock easily.

Referring to Fig.1, Fig. 2, Fig. 3 and Fig. 4.In the present embodiment, positioning groove seat 3 and single head 1 are integrally formed, and the locating slot Seat is in horizontally disposed U-shaped shape.In addition, offering a pair of symmetrical fixation hole 31 in positioning groove seat 3, pin shaft 4 is sealed solid Surely it is installed in the fixation hole 31, which can be copper pin.

Referring to Fig.1, Fig. 2, Fig. 3 and Fig. 4.The turning end 21 of pulling-on piece offers a groove 23, and it is recessed that reset spring 5 is embedded at this In slot 23, and reset spring upside 51 is in contact with 23 inner top surface of groove.In addition, offering one in the turning end 21 of pulling-on piece To symmetrical through-hole 24, groove 23 is located at this between through-hole 24, and the turning end 21 of pulling-on piece passes through the through-hole 24 and pin shaft 4 It is rotatably connected, which can be torsional spring.

In addition, referring to Fig.1, Fig. 2, Fig. 3 and Fig. 4.Location hole 12 is offered on the upside of single head 1,52 cards are set on the downside of reset spring In in location hole 12.

Referring to Fig.1, Fig. 2, Fig. 3 and Fig. 4.When the utility model is installed, copper pin 4 is first passed through to the fixation hole in left side, then will The copper pin be pushed into sequentially pass through to the right the through-hole in left side, reset spring, right side through-hole, be inserted into the fixation hole on right side, make copper The both ends of pin are located in two fixation holes and complete to fix.

In use, pulling-on piece 2 is affixed with 1 upper side of single head downwards under the elastic force effect of the reset spring 5 under normal condition Close, and purl 22 be inserted into purl hole 11 complete it is self-locking；When pulling-on piece 2 is turned over unlock, due on the upside of reset spring 51 and groove 23 inner top surfaces are in contact, therefore the turning end 21 of pulling-on piece can press reset spring upside 51 and rotate around pin shaft 4, and due to multiple It 52 is arranged in location hole 12 on the downside of the spring of position, therefore when the turning end 21 of pulling-on piece is pressed 51 on the upside of reset spring, reset spring Opposition with pull-tab；After shedding the power of pull-tab application, pulling-on piece just can be in the reversed work of reset spring Firmly lower reinstatement is completed self-locking again.

The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto, All non-essential modifications to the present invention made by this concept should belong to the row for invading scope of protection of the utility model For.
