Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
The a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under not making creative work premise, broadly falls into the scope of protection of the invention.
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings:
First upper and lower, left and right described in present embodiment etc. and the upper and lower, left and right etc. described in accompanying drawing it are noted that
Unanimously, but it is not intended that limitation of the invention further.
The operating forceps described in embodiment of the present invention as shown in Figures 1 to 4, including a pedestal 1, front hand grip 2, defensive position
Handle 3 and push rod 4；Wherein, front hand grip 2 and back handle 3 are arranged on the lower section grasping for user of pedestal 1, and push rod 4 includes pushing away
Bar front portion and push rod rear portion, in Fig. 1, separate two parts are the anterior boundary with push rod rear portion of push rod, the one of push rod rear portion
End (left end in accompanying drawing) is connected with pedestal 1, and the other end has the first installation portion；One end (right-hand member in accompanying drawing) that push rod is anterior
Two chucks are installed, the other end have the second installation portion, the first installation portion and the second installation portion match by anterior for push rod with
Push rod rear portion links together；Push rod is anterior all includes inner push-rod 42 and outer push rod 41 with push rod rear portion, and chuck includes the first folder
51 and second chuck 52, the first chuck 51 inner push-rod 42 anterior with push rod is connected, outside the second chuck 51 is with push rod front portion
Push rod 41 is connected；As a preferred mode, the first installation portion includes a mounting groove, and the second installation portion has and described peace
The holding section that tankage matches, holding section is placed in mounting groove inside and is connected with mounting groove by screw, pedestal 1 also has
Shifting disc 6, shifting disc 6 is fixedly linked with push rod 4, pedestal 1 also has positioner 7 for limiting the rotation of shifting disc 6, dials
There is on Moving plate 6 protuberance matched with positioner 7
The operation principle of the present invention mainly includes two parts, clamps, rotates and dismantles.
For clamping, as a preferred mode it is: the first chuck 51 is hinged with the second chuck 51 and phase
Being connected in a certain termination of push rod 4, the second chuck 52 is fixedly linked with outer push rod 41, and the first chuck 51 is connected with inner push-rod 42, interior
Push rod 42 is positioned at the inside of outer push rod 41, and inner push-rod 41 can push rod 42 internal slide the first chuck 51 can be driven around first outside
Chuck 51 is freely rotatable with the hinged place of the second chuck 52, and connecting portion phase is passed through in another end away from chuck of inner push-rod 42
Being connected with draw ring 43, it addition, pedestal 1 inside is stretched in one end of aforesaid back handle 3, and can move by opposite base, back handle 3 is positioned at
The end of base interior 1 has an eave tile 31, and eave tile 31 is through draw ring 43, when defensive position is pressed in the direction of operator's forward handle 2
During handle 3, eave tile 31 rearward movement, drive draw ring 43 rearward movement simultaneously, because draw ring 43 is connected with inner push-rod 42, so by drawing
Bad 43 drive inner push-rods 42, are further driven to the first chuck 51 and rotate to the direction of the second chuck 52, so that two chucks
Mutually clamping.As a preferred mode, the inside of pedestal 1 has an occlusion part, and occlusion part and back handle 3 stretch into pedestal
Being provided with elastic device 9 between internal part, elastic force produced by elastic device 9 can ensure that back handle 3 moves at forward handle 2
Dynamic is eave tile 31 rearward movement of its end.Second, for rotating, as a preferred mode be: install on pedestal 1
Shifting disc 6 be connected with the outer push rod 41 of push rod, when rotate shifting disc 6 time, outer push rod 41 follows rotation, at the first chuck 51
Rotate with driving inner push-rod 42 under the active force of the second chuck 52 junction simultaneously, so that whole push rod 4 rotates, therefore,
First chuck 51 and the second chuck 52 follow rotation, thus reach the purpose that chuck of the present invention is freely rotatable, it can be seen that due to
There is between draw ring 43 and inner push-rod 42 connecting portion, therefore, the rotation of shifting disc 6 can not 360 degree freely rotatable, because of
This, the pedestal 1 of the invention described in present embodiment is provided with positioner 7, and present embodiment has been preferably provided with two relatively
In the positioner 7 that central plane of the present invention is symmetrical, positioner 7 matches with the protuberance 8 on shifting disc thus reaches
Limit the purpose that shifting disc 6 is freely rotatable.3rd, for dismounting, as a preferred mode be: push rod 4 is divided into
Push rod front portion and two, push rod rear portion part, one connecting portion of the inner push-rod of two parts can realize the function of easy removal,
Connecting portion herein can be the first above-mentioned installation portion and the second installation portion, it is also possible to is the structure of other forms, in reality
During use, only need to change by chuck that the is push rod after using is anterior and that be connected with push rod front portion, use and grasp
Make very convenient, it is possible to be greatly saved use cost.
As a preferred mode, the first chuck 51 and the second chuck 52 are divided into two-layer, and outer layer is by metal material system
Becoming, internal layer is made up of insulant, can reduce the extra scald in operation technique caused patient the most simultaneously, reduces
The misery of patient.
It should be noted that in this article, the relational terms of such as first and second or the like is used merely to a reality
Body or operation separate with another entity or operating space, and deposit between not necessarily requiring or imply these entities or operating
Relation or order in any this reality.And, term " includes ", " comprising " or its any other variant are intended to
Comprising of nonexcludability, so that include that the process of a series of key element, method, article or equipment not only include that those are wanted
Element, but also include other key elements being not expressly set out, or also include for this process, method, article or equipment
Intrinsic key element.In the case of there is no more restriction, statement " including ... " key element limited, it is not excluded that
