The utility model is further provided with: the inner side of the shell is provided with an accommodating groove communicated with the cavity, the area of the bottom of the accommodating groove is larger than the opening area of the accommodating groove, a round block with an arc surface facing the cavity is arranged in the accommodating groove, the bottom of the accommodating groove is fixedly connected with a spring, and the other end of the spring is fixedly connected with the round block.
Through adopting above-mentioned technical scheme, after the fly leaf removes to the button department the fly leaf will extrude the button and then extrude the spring, and the spring extrusion gives the reaction force of button, consequently the button can extrude the fly leaf to increase the stability of fly leaf.
The utility model is further provided with: one end of the shell is provided with a concave plate.
By adopting the technical scheme, the concave plate is convenient for moving the shell.
The utility model is further provided with: the side of the shell is provided with a label.
Through adopting above-mentioned technical scheme, the setting of label is convenient for the technician discerns the casing.
The utility model is further provided with: the side face of the piston rod is provided with an annular groove which is recessed inwards.
Through adopting above-mentioned technical scheme, in the arc board can block into the ring channel, stability when increasing arc board and piston rod joint.
In summary, the utility model has the following beneficial effects:
one end and the threaded rod threaded connection of L form pole, the other end of L form pole is in the casing, start the double-end motor and drive the output shaft and rotate and then drive the threaded rod and rotate, because the one end of L form pole is in the casing and can only remove along the length direction of threaded rod, after the threaded rod rotated, because the connecting rod is connected with L form pole, consequently the connecting rod will unable rotation can only remove and then drive L form pole along the length direction of threaded rod and remove, two L form poles will remove and then drive the arc board and remove towards the direction that is close to each other towards each other, until two arc board extrudees the piston rod that is in between two arc boards, realize locking piston rod's purpose.
