Accompanying drawing explanation
The structural representation of the stapler that Fig. 1 provides for the embodiment of the present invention;
Fig. 2 is the partial enlargement figure at the A place shown in Fig. 1;
Fig. 3 is the explosive view of the outer safety interlock of the stapler shown in Fig. 1.
Embodiment
The core of the present invention is to provide the safety interlock of a kind of stapler, and the safety effect of these safety interlock is better. Another core of the present invention is to provide a kind of stapler comprising above-mentioned safety interlock.
In order to make those skilled in the art understand the technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1-Fig. 3, in a kind of embodiment, the safety interlock of the stapler that the embodiment of the present invention provides, comprise fixing handle and the pointer 3 being installed on fixing handle and outer insurance 5, also comprising the insurance push-and-pull plate 8 that the straight push rod 6 of interior the insurance 4 and stapler being arranged on fixing handle is connected, pointer 3, interior insurance 4 and outer insurance 5 are all connected with insurance push-and-pull plate 8. Insurance push-and-pull plate 8 can synchronization control pointer 3, interior insurance 4 and outer insurance 5, rotate the rotation handle 2 of stapler, insurance push-and-pull plate 8 drives pointer 3, interior insurance 4, outer insurance 5 is rotated, during to proper states, pointer 3 indicates correct region, and in now, insurance 4 and outer insurance 5 are all opened, the free handle 1 of stapler can be held, thus has continued operation technique. The safety interlock of the stapler that the embodiment of the present invention provides, owing to insurance push-and-pull plate 8 can with control pointer 3, interior insurance 4 and outer insurance 5, stapler is operationally, pointer 3, interior insurance 4, outer insurance 5 are synchronized with the movement, ensure that interior insurance 4, outer insurance 5 are consistent with pointer 3, the safety effect of outer insurance 5 is better. Insurance push-and-pull plate can arrange pointer drag hook 81, interior insurance drag hook 82 and insure drag hook outward, thus pull pointer 3, interior insurance 4 and outer insurance 5 rotation.
In addition, insurance push-and-pull plate 8 can abut against with the coupling end of outer insurance 5 and insure and be provided with insurance hole 83 on push-and-pull plate 8, and the coupling end of outer insurance 5 can by insurance hole 83. The original state of stapler, owing to being provided with insurance push-and-pull plate 8, the coupling end of outer insurance 5 offsets with insurance push-and-pull plate 8, and outer insurance 5 cannot be opened, and rotates the rotation handle 2 of stapler, the straight push rod 6 of stapler drives push-and-pull plate, when stapler arrives proper states, the insurance hole 83 of insurance push-and-pull plate 8 is corresponding with the coupling end of outer insurance 5, and now the coupling end of outer insurance 5 is by insurance hole 83, then can open outer insurance 5, carry out next step operation. Outer insurance 5 device of stapler provided by the invention, owing to being provided with insurance push-and-pull plate 8, time stapler arrives proper states, outer insurance 5 just can be opened, when ensure that outer insurance 5 is opened, stapler is in suitable state, and the safety effect of outer insurance 5 is better. The coupling end of outer insurance 5 refers to the one end being connected in outer insurance 5 with insurance push-and-pull plate 8. Outer insurance 5 coordinates with interior insurance 4, makes safety effect better.
In addition, straight push rod 6 is provided with the adjustment block 7 that can slide relative to straight push rod 6 and fix, regulates block 7 to be connected with insurance push-and-pull plate 8. Regulate block 7 can regulate the position of insurance push-and-pull plate 8, thus the position making the position in insurance hole 83 and interior insurance 4 is relatively accurate, makes safety effect better.
Further, regulating block 7 for elastic u-shaped adjustment block, elastic u-shaped regulates block to be clipped on straight push rod 6. Elastic u-shaped regulates block to have elasticity and can be clipped on straight push rod 6, can move elastic u-shaped so fast and regulate block and easier to mount.
Further, regulate and block 7 is provided with fixed orifices, in fixed orifices, be provided with set screw. Use set screw to install and regulate block 7, make adjustment block 7 fixing more stable and being convenient to the mobile position regulating block 7 on straight push rod 6.
Further, one end of the close interior insurance 4 of the sliding end of interior insurance 4 and the free handle 1 of stapler is circular arc shape, and one end of the close interior insurance 4 of the sliding end of interior insurance 4 and the free handle 1 of stapler matches. In like this, insurance 4 can more easily be opened, and the opening procedure of interior insurance 4 is more level and smooth. The sliding end of interior insurance 4 refers to the one end contacted in interior insurance 4 with free handle 1, and one end of the close interior insurance of free handle 1 refers on free handle 1 with interior insurance 4 to the position connect.
In addition, one end of the close outer insurance of the sliding end of outer insurance 5 and the free handle 1 of stapler is circular arc shape, and one end of the close outer insurance of the sliding end of outer insurance 5 and the free handle 1 of stapler matches. Outer like this insurance 5 can more easily be opened, and the opening procedure of outer insurance 5 is more level and smooth. The sliding end of outer insurance 5 refers to the one end contacted in outer insurance 5 with free handle 1, and one end of the close outer insurance 5 of free handle 1 refers on free handle 1 with outer insurance 5 to the position connect.
The stapler that the embodiment of the present invention provides, the above-mentioned safety interlock comprising device body and being connected with device body, the structure of other parts with reference to prior art, can repeat no more herein.
Above stapler provided by the present invention and safety interlock thereof are described in detail. Applying specific case herein the principle of the present invention and enforcement mode to have been set forth, illustrating of above embodiment is for helping the method understanding the present invention and core concept thereof, not limiting the scope of the present invention. , it is also possible to the present invention carries out some improvement and modification, it is noted that for those skilled in the art, under the premise without departing from the principles of the invention these improve and modify in the protection domain also falling into the claims in the present invention.
