Abstract
The invention provides a novel F-shaped hand screw clamp. The novel F-shaped hand screw clamp comprises a guiding rod, a fixed arm, a movable arm, a locking screw rod and a locking handle, wherein the fixed arm is fixed at one end of the guiding rod, and a pressing table is arranged at the end part of the fixed arm; a sleeve hole is formed in one end of the movable arm, the movable arm is mounted on the guiding rod in a sleeving manner through the sleeve hole, and a locking hole is formed in the other end of the movable arm; a U-shaped groove is formed in one end of the locking screw rod, the locking handle is movably hinged to a position in the U-shaped groove through a pin shaft, a rubber pad coats the outer side of the locking handle, and the other end of the locking screw rod penetrates through the locking hole and is matched with the pressing table; V-shaped skid-proof teeth are arranged on the lateral wall of one side of the guiding rod, and inner teeth matched with the skid-proof teeth are arranged in the sleeve hole. The novel F-shaped hand screw clamp disclosed by the invention has the advantages of simple structure, convenience in operation, good practicality and sliding resistance.
Description
Technical field
The present invention relates to aid technical field, refer in particular to a kind of novel F type carpenters' clamp.
Background technology
F type carpenters' clamp is the instrument doing woodwork indispensability, and its structure simply uses dexterity, is the good assistant making woodwork.The operation principle of F type carpenters' clamp is: to slide lever arm with hand, during slip lever arm must with guide rod keeping parallelism, otherwise it is sliding motionless, slide into the width of the workpiece, namely can workpiece be placed between two arm of forces, then slowly rotate the screw rod bolt on dynamic lever arm, be used for clamping work pieces, adjust to applicable elasticity and let go and can complete workpiece and fix.Guide rod there is bayonet socket, guide rod slippage can be prevented, guarantee can not loosen when clamping work pieces, two arm of forces respectively have one to add block, can prevent from not doing worker employed in a plant nursery's part while clamping work pieces energetically, guarantee the surfacing of workpiece.It is all smooth that existing F presss from both sides guide rod, and need to catch lever arm with hand during use locking and just can lock, otherwise can offset, in use lever arm also easily slides; And present set lever is all 1 shape, needs larger strength during locking workpiece, also easily slide during rotation, inconvenient operation.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of structure novel F type carpenters' clamp that is simple, easy to operate, practical, not skating.
For achieving the above object, technical scheme provided by the present invention is: a kind of novel F type carpenters' clamp, it includes guide rod, fixed arm, lever arm, tie down screw, set lever, wherein, fixed arm is fixed on guide rod, fixed arm end is provided with presents a theatrical performance as the last item on a programme, lever arm one end is provided with trepanning, and by trepanning movable set on guide rod, the lever arm other end is provided with locking hole, tie down screw one end is provided with U-lag, set lever is movably articulated in U-lag by bearing pin, rubber cushion is coated with outside set lever, the tie down screw other end matches with presenting a theatrical performance as the last item on a programme through locking hole, guide rod side sidewall is provided with V-arrangement anti-slop serrations, is provided with the internal tooth matched with anti-slop serrations in trepanning.
Described trepanning hole size is greater than guide rod sectional dimension.
Described tie down screw one end is provided with circular hinge platform, and U-lag is positioned on circular hinge platform.
The present invention is after employing such scheme, and the V-arrangement anti-slop serrations on guide rod sidewall effectively prevents lever arm after locking from sliding, and the locking that F is pressed from both sides is convenient, simple; Set lever adopts the mode be movably hinged, and when carrying out workpiece locking, by set lever to a sideway swivel, makes, in 7 shapes between itself and tie down screw, can easily work be locked without the need to great strength.This programme has structure advantage that is simple, easy to operate, practical, not skating.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with institute's drawings attached, the invention will be further described, preferred embodiment of the present invention is: see accompanying drawing 1, one described in the present embodiment novel F type carpenters' clamp includes guide rod 1, fixed arm 2, lever arm 3, tie down screw 4, set lever 5, wherein, fixed arm 2 is fixed on guide rod 1 one end, fixed arm 2 end is provided with presents a theatrical performance as the last item on a programme 6, lever arm 3 one end is provided with trepanning 7, and by trepanning 7 movable set on guide rod 1, lever arm 3 other end is provided with locking hole, tie down screw 4 one end is provided with U-lag 8, set lever 5 is movably articulated in U-lag 8 by bearing pin 9, rubber cushion is coated with outside set lever 5, tie down screw 4 other end 6 to match with presenting a theatrical performance as the last item on a programme through locking hole, described tie down screw 4 one end is provided with circular hinge platform, U-lag 8 is positioned at circular hinge platform top guide bar 1 side sidewall and is provided with V-arrangement anti-slop serrations 10, and be provided with the internal tooth matched with anti-slop serrations 10 in trepanning 7, described trepanning 7 hole size is greater than guide rod 1 sectional dimension.V-arrangement anti-slop serrations on the guide rod sidewall of the present embodiment effectively prevents lever arm after locking from sliding, and the locking that F is pressed from both sides is convenient, simple; Set lever adopts the mode be movably hinged, and when carrying out workpiece locking, by set lever to a sideway swivel, makes, in 7 shapes between itself and tie down screw, can easily work be locked without the need to great strength.This programme has structure advantage that is simple, easy to operate, practical, not skating.
The embodiment of the above is only the preferred embodiment of the present invention, not limits practical range of the present invention with this, therefore the change that all shapes according to the present invention, principle are done, all should be encompassed in protection scope of the present invention.
