Specific embodiment
The feature and principle of the present invention are described in detail below in conjunction with accompanying drawing 1- Figure 13, illustrated embodiment is only used for solving
The present invention is released, protection scope of the present invention is limited with this not.
As Figure 1-Figure 4, the invention includes 2 two large divisions of joint 1 and joint shell, and its center tap includes columned
Body 101 and two fix bars 102 being vertically installed on columned body.Fix bar extends in columned in vitro.
Joint shell 2 includes the columned sleeve 201 with columned body fits, is provided with and matches somebody with somebody with two fix bars at the top of sleeve
The draw-in groove of conjunction, when carrying out earth lead and hanging, causes fix bar to fix in the bottom of draw-in groove in joint insertion sleeve.
As shown in figure 8, the draw-in groove arranged at the top of sleeve is the direct neck 202 parallel with sleeve, facilitate the insertion of fix bar,
Avoid the problem that the J-type draw-in groove shown in Fig. 5 installs inconvenience.As shown in figure 8, corresponding direct neck bottom position sets on cylinder
There are two symmetrical semicircular chutes 203, and a slide block 3 is correspondingly provided with each chute.The cross section of chute can set
It is calculated as T-shaped, the bottom margin of chute is adjacent to the top of fix bar after joint insertion sleeve.The complete phase of the slide block structure
With slide block can rotate movement along its circumference direction in described chute.Slide block is provided with protrusion near one end of direct neck
Shifting block 301, shifting block are used for after joint and joint shell coordinate and install the movement for limiting fix bar 102.The width of shifting block is more than
The width of direct neck 202, it is ensured that shifting block prevents fix bar from moving up and down the firm spacing of fix bar.In addition, can be in shifting block
Bottom holds out against the one side of fix bar and adds rubber layer, prevent abrasion of the shifting block to fix bar, and also increase fix bar and shifting block rub
Power is wiped, more firm fixation of the shifting block to fix bar is realized.
As shown in fig. 10 and fig. 12, its circumference face corresponding two slide positions in bottom symmetrical be provided with two jointed shafts
4, driving lever 5 is correspondingly hingedly connected with jointed shaft.Driving lever is elongate rod, is divided into first paragraph 501, second segment from top to bottom
502 and the 3rd section 503, first paragraph and the 3rd section are parallel vertical bar, and first paragraph and the 3rd section are connected by the second segment for inclining
One is connected in, the second end is by torsion spring and jointed shaft and sleeve connection.And driving lever is connected with jointed shaft by torsion spring 6, driving lever
Top is that first paragraph is corresponding with shifting block position, and first paragraph is connected with shifting block by spring, and shifting block can be in torsion spring and spring effect
Under automatically reset.The bottom of driving lever extends downwardly, stir driving lever bottom action when driving lever at the top of stir shifting block to direct neck
Direction is moved, and when shifting block is moved to direct neck position, the bottom of shifting block is stuck at the top of the fix bar in insertion direct neck, such as Figure 13
Shown.
The accuracy spacing in order to be further ensured that shifting block, prevents at firmly excessive slide block cylinder chute end cunning, in chute
Be provided near one end of direct neck play the block 204 that spacing protrusion is carried out to shifting block.I.e. two chutes cross over direct neck,
One end of chute in the side of direct neck, the opposite side of the other end of chute in direct neck.
During use, as shown in Fig. 9-Figure 13, first joint is aligned up and down with joint shell, while ensureing that shifting block is not directly blocking
The top position of groove, i.e. direct neck are not hindered by shifting block.As shown in Figure 10 and Figure 11, joint is inserted in joint shell,
Fix bar is stuck in the bottom of direct neck.Then the bottom of the 3rd section of driving lever is stirred to joint shell central axial direction, now
Driving lever is rotated around jointed shaft, while the first paragraph of driving lever is also moved to joint shell central axial direction, stirs shifting block to straight card
Groove direction is moved, until shifting block turns to the locking that the corresponding fix bar top position of direct neck is realized to fix bar, such as Figure 12 and
Shown in Figure 13.
When hanging up properly earth lead and removing head, driving lever is unclamped, driving lever is rotated under the active force of torsion spring, the first paragraph of driving lever
Drive shifting block to automatically reset under the force of a spring, remove head.
The inventive structure is simple, and easy to use, technical requirements difficulty is low, is easy to operate.Insert in joint and depart from sleeve
When, all joint need not be adjusted repeatedly to rotate to an angle fix bar is laterally embedded in opening draw-in groove and be fixed, but directly
In the fix bar of joint vertically insertion sleeve, then will stir driving lever drive shifting block fix bar is carried out spacing.Need
Driving lever is unclamped when removing head, and slide block automatically resets under driving lever drive, and vertical direction force is removed.
When joint is embedded and splits, longitudinal push-and-pull is only needed, be not required to rotation and fix, reduce sending out for joint blocking case
Raw；On the other hand, achieved a butt joint the fixation of head using magneto Magnet.Also ensure that while convenient use and to be fixedly connected
Reliability.
Above-described embodiment is only the description carried out by the preferred embodiment of the present invention, and not the scope of the present invention is entered
Row limit, on the premise of without departing from design spirit of the present invention, relevant technical staff in the field to the present invention various modifications and
Improve, all should expand in protection domain determined by claims of the present invention.
