The invention discloses one kind to grab crab instrument, including the vertically arranged main support rod of central shaft, main support rod upper position is provided with rectangular through-hole, main support rod lower end is connected with rear fender vertically, the horizontal connection of rear fender lower end has lower supporting plate, the inclined direction of rotating bar passes through the rectangular through-hole in main support rod, and the bar segment both sides that rotating bar is located in rectangular through-hole are rotatablely connected by rotating shaft and rectangular through-hole respective side side wall respectively, and rotating bar lower end is connected with front pressuring plate.The present invention is simple in construction, easy to use, and a kind of reliable instrument is provided for night crabbing, is avoided that staff's finger contacts with the direct of crab, improves night crabbing efficiency, and reduce working strength.
Description
Technical field
The present invention relates to crabbing field of tool, specifically one kind grabs crab instrument.
Background technology
It in crab cultivation, can be caught after annual September-October crab maturation, crabbing net can be used during seizure
Or trap for catching crabs enters water crabbing, can also be caught when night crab debarks.In the prior art, night crabbing relies on work people
Member catches crab with hand, certain risk be present, especially for the people of seldom crabbing, the wind that finger can be clamped by crab be present
Danger, and crabbing of bending over for a long time can also adversely affect to staff's health.
The content of the invention
It is an object of the invention to provide one kind to grab crab instrument, to solve the problems, such as that prior art night crabbing is present.
In order to achieve the above object, the technical solution adopted in the present invention is：
One kind grabs crab instrument, it is characterised in that：Including the vertically arranged main support rod of central shaft, main support rod upper position is provided with
The rectangular through-hole of main support rod is radially penetrated, and the long side of rectangular through-hole is parallel to main support rod central axis direction, main support
Bar lower end is connected with rear fender vertically parallel to the radial position of rectangular through-hole broadside, and the horizontal connection of rear fender lower end has lower support
Plate, also include rotating bar, the inclined direction of rotating bar passes through the rectangular through-hole in main support rod, and rotating bar is located at square
Bar segment both sides in shape through hole are rotatablely connected by rotating shaft and rectangular through-hole respective side side wall respectively, rotating bar lower end parallel to
The radial position of rectangular through-hole broadside is connected with front pressuring plate, and front pressuring plate is perpendicular to rotating bar lower end surface.
Described one kind grabs crab instrument, it is characterised in that：Main support rod, rotation pole length are identical, main support rod, rotating bar
Upper end be connected to rubber handle.
Described one kind grabs crab instrument, it is characterised in that：The rotating shaft outer end is respectively from main corresponding to rectangular through-hole side wall
Support bar sidepiece passes, and there is swivel nut rotating shaft outer end by Screw assembly respectively, and torsion spring, torsion spring are respectively installed with each rotating shaft
One end is separately fixed in rotating bar, and the torsion spring other end is separately fixed at main support rod sidepiece, realizes that rotating bar turns by torsion spring
Reset after dynamic.
The invention provides one kind to grab crab instrument, is caught when being debarked available for night crab.Singlehanded grasping during use
The rubber handle of main support rod, rotating bar, then first lower supporting plate is shoveled into crab rear end lower section, and rear fender is pressed in crab
Rear end, it is then singlehanded to clamp main support rod, rotating bar, rotating bar is turned to front pressuring plate and be pressed in crab front end, you can by ground
Upper crab is picked up.Usually between main support rod and rotating bar at an angle, rotating bar can be achieved under torsion spring effect after work
Reset.
The present invention is simple in construction, easy to use, provides a kind of reliable instrument for night crabbing, is avoided that staff
Finger directly contacts with crab, improves night crabbing efficiency, and reduce working strength.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is spindle portion positive view of the present invention.
Embodiment
As shown in Figure 1 and Figure 2, one kind grabs crab instrument, including the main support rod 1 that central shaft is vertically arranged, on main support rod 1

End horizontal connection has lower supporting plate 4, also includes rotating bar 5, and 5 inclined direction of rotating bar passes through the rectangle in main support rod 1
Through hole 2, and the bar segment both sides that rotating bar 5 is located in rectangular through-hole 2 are turned by rotating shaft 7 and the respective side side wall of rectangular through-hole 2 respectively
Dynamic connection, the lower end of rotating bar 5 are connected with front pressuring plate 6 parallel to the radial position of the broadside of rectangular through-hole 2, and front pressuring plate 6 perpendicular to
The lower end surface of rotating bar 5.
Main support rod 1, the length of rotating bar 5 are identical, and main support rod 1, the upper end of rotating bar 5 are connected to rubber handle 8.
The outer end of rotating shaft 7 passes from the sidepiece of main support rod 1 corresponding to the side wall of rectangular through-hole 2 respectively, and the outer end of rotating shaft 7 leads to respectively
Crossing Screw assembly has swivel nut 9, and torsion spring 10 is respectively installed with each rotating shaft 7, and the one end of torsion spring 10 is separately fixed in rotating bar 5,
The other end of torsion spring 10 is separately fixed at the sidepiece of main support rod 1, and the reset after the rotation of rotating bar 5 is realized by torsion spring 10.
