It is bigger, it is relatively elaborate.
Utility model content
Based on this, it is necessary to provide a kind of electroplating clamp, including fixing piece and movable part, the side setting of the fixing piece
There are first support bar, second support bar and the first clamping part, first retaining part is in the end of the fixing piece, and described
Movable part is hinged on two support rods, one end of the movable part corresponds to first clamping part and is provided with the second clamping part, institute
The other end for stating movable part extends towards the first support bar, and is more than the first support bar far from the second support bar
Side side wall, the top of the first support bar is hinged with handle, and the handle includes being located at itself and first support bar
The operation portion and interconnecting piece of hinged place two sides, the end of the interconnecting piece and the outer surface of the movable part offset, the activity
The inner surface of part is provided with elastic component, and the other end of the elastic component is fixedly connected with the inner surface of the fixing piece, the bullet
Property part is between the first support bar and second support bar.
Wherein, the material of the utility model is stainless steel, and movable part is movably connected in the second support by fixed finger setting
On bar, handle is movably connected in first support bar by fixed finger setting.
Elastic component is in confined state always in the present invention, and compressed resilient element urges movable part is far from the
One end of two clamping parts is against the interconnecting piece on handle, and the first clamping part contacts with each other with the second clamping part at this time；Need clamp
When the plate of road, the operation portion of pulling handle pulls operation portion outwardly, rotates handle along the hinged place of itself and first support bar,
The interconnecting piece of handle can one end by movable part far from clamping part toward internal pressure so that the first clamping part and the second retained part
From then wiring board is placed between the first clamping part and the second clamping part, unclamps handle, the elastic force of elastic component can make activity
The one end of part far from the second clamping part is pushed up outwardly, so that the first clamping part is close to the second clamping part, and in elastic component elastic force
Effect is lower to clamp wiring board, wherein elastic component can use the elastic component of the biggish prior art of elastic force.
Handle in the utility model utilizes lever principle, and the length of operation portion is longer than the length of interconnecting piece, and operator makes
With lesser operating force, that is, openable first clamping part and the second clamping part, it is convenient to operate, time saving and energy saving.
Preferably, the length ratio of the interconnecting piece and the operation portion is 1:5-1:10.
Preferably, the length that the movable part is located at the part on the left of its hinged place is longer than the movable part and is located at it hingedly
Locate the length of the part on right side.
The structure of movable part utilizes lever principle, using its hinged place with second support bar as separation, on the left of length
Degree is longer than the length on the right side of it, when the elastic component of movable part lower end up pushes the left side of movable part, it is only necessary to lesser elastic force

Block corresponds to the installation axle and is provided with mounting hole, and the mounting hole is sheathed on the installation axle, and can be rotated with the installation axle
Cooperation.
Wherein installation axle and mounting hole transition fit, the radial clearance between mounting hole and installation axle is minimum, can the company of preventing
The radial direction that block is connect relative to installation axle is mobile, to guarantee the stability of grip block.
There is certain gap, so that linking arm can be second between link block and the side wall and slot bottom of the second mounting groove
Mounting groove can have certain swing space along the axis of installation axle；The cell wall and slot bottom of grip block and the first mounting groove tool
There is certain gap, enables grip block that there is certain swing space along the axis of installation axle, to guarantee that grip block exists
The surface of assist side can be ideally bonded when clamping wiring board.
When second clamping part presses to the first clamping part by elastic component driving to clamp wiring board, the surface of the second clamping part without
Method remains parallel with the surface of the first clamping part, thus when pressing from both sides the wiring board of different-thickness, it will lead to the first clamping
The contact area of portion or the second clamping part and wiring board is too small and causes pressure excessive and then damages wiring board, and this is practical new
Grip block on second clamping part of type is when contacting wiring board, since grip block can be swung around installation axle, clamping
Plate can be bonded well in the circuit board, and after wiring board is clamped between the first clamping part and the second clamping part, can be protected
Hold parallel with the surface of the first clamping part, i.e., grip block and the first clamping part can be perfectly bonded with wiring board, therefore this reality
With novel larger with the contact area of wiring board, it can effectively prevent its and press from both sides bad wiring board.
