Portion, the left and right sides of the top cover 4 offer the first threaded hole 7, and the left and right sides of the kidney slot 5 is located at rectangle matrix box
Perforation offers the second threaded hole 8 vertically on 1, and the top cover 4 is mounted on the first threaded hole 7 and the second spiral shell by the first bolt 9
The top of rectangle matrix box 1 is fixed in pit 8；
The front and rear sides at the top of the rectangle matrix box 1 offer the third threaded hole 10 for penetrating into 1 bottom of rectangle matrix box,
The third threaded hole 10 is located at the right side of the second threaded hole 8, and the inner vertical of the third threaded hole 10 is equipped with the second spiral shell
Rasp bar 11；
There are two the rectangular block 12 is set, one end of two rectangular blocks 12 offers through-hole 13, the rectangle matrix box 1
The right side of front and rear sides wall offer perforation 16, two rectangular blocks 12 are inserted into the inside of rectangle matrix box 1, the shifting
Lever 14 passes through through-hole 13 and perforation 16, and the outer cover of the mobile bar 14 is equipped with spring 15, and the spring 15 is located at two squares
Between shape block 12, two rectangular blocks 12 are located at the two sides of strut 3, and two rectangular blocks 12 are located at two second spiral shells
Between rasp bar 11.
Specifically, the through-hole 13 is vertical with rectangular block 12, and the both ends of through-hole 13 are arranged for no chamfering, improve through-hole
Shearing force between 13 and mobile bar 14.
Specifically, the distance between former and later two described second threaded rod, 11 inner sidewalls are identical as the length of strut 3, work as support
When bar 3 is parallel with mobile bar 14, it ensure that mobile bar 14 and rectangular block 12 are perpendicular.
Specifically, the bottom of first bolt 9 and the second threaded rod 11 is set with nut 17, improves whole steady
It is qualitative.
Specifically, the specification of two rectangular blocks 12 is identical.
Structural principle: original state is as shown in Fig. 2, at this time due to the effect of the elastic force of spring 15, by the right side of rectangular block 12
Side stay is opened, so that an angle less than 90 degree is formed between rectangular block 12 and mobile bar 14, so that through-hole 13 and mobile bar 14
Between form shearing force, as shown in figure 3, mobile bar 14 is locked, reversible lock is carried out to mobile bar 14 by two rectangular blocks 12
Tightly, locking effect is good；
As shown in figure 3, need to only hold the horizontal rotation counterclockwise of holding rod 21 when needing that mobile bar 14 is mobile, drive 3 inverse time of strut
Needle rotation, the left side of two rectangular blocks 12 is strutted, at this time the right side retraction of two rectangular blocks 12, at this time through-hole 13 and mobile bar
Shearing force disappearance between 14 is gradually reduced, and mobile bar 14 can gradually move, when strut 3 is parallel with mobile bar 14, at this time

Side, through-hole 13 are located at 12 left side of rectangular block；
Structural principle: under original state as shown in figure 11, due to the effect of the elastic force of spring 15, the left side of rectangular block 12 is against
On strut 3, so that an angle less than 90 degree is formed between rectangular block 12 and mobile bar 14, so that through-hole 13 and mobile bar 14
Between form shearing force, mobile bar 14 is locked, by two rectangular blocks 12 to mobile bar 14 carry out bidirectional locking, locking effect
It is good；
When needing that mobile bar 14 is mobile, the horizontal rotation counterclockwise of holding rod 21 need to be only hold, strut 3 is driven to rotate counterclockwise, it will
The left side of two rectangular blocks 12 struts, at this time the right side retraction of two rectangular blocks 12, at this time between through-hole 13 and mobile bar 14
Shearing force disappearance is gradually reduced, and mobile bar 14 can gradually move, when strut 3 is parallel with mobile bar 14, mobile bar 14 at this time
Perpendicular with rectangular block 12, shearing force between through-hole 13 and mobile bar 14 disappears at this time, and as shown in figure 12, mobile bar 14 can be with
Smoothly moved in through-hole 13.
It is rotated clockwise or counterclockwise it is emphasized that no matter needing to hold horizontal holding rod 21 in two schemes, it
Effect is the angle adjusted between strut 3 and rectangular block 12, and original state lower supporting rod 3 and 12 angle of rectangular block are maximum, through-hole 13
Shearing force between mobile bar 14 is maximum, no matter rotates horizontal holding rod 21 clockwise or counterclockwise, adjusts strut 3 and rectangle
Angle between block 12 can all increase, and the most conference of the shearing force between through-hole 13 and mobile bar 14 is gradually reduced, when strut 3 and square
When perpendicular between shape block 12, the shearing force between through-hole 13 and mobile bar 14 disappears, and for convenience, two embodiments are only
It is that one of rotation mode of corresponding selection explains.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
