Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of rational in infrastructure, easy to operate at above-mentioned deficiency, and a kind of sample punch die tool of high efficiency.

For solving the problems of the technologies described above, this sample punch die tool comprises shell, its design feature is: comprise support, support top is provided with vertical sleeve, be fitted with the striker that slides up and down along sleeve lining in the sleeve, the part that striker is positioned at sleeve is installed with backing pin, and the spring that striker is popped up by backing pin is installed in the sleeve.

The sample punch die tool of this structure is realized easy to operate and high efficiency by the frame reciprocating structure.

The frame reciprocating structure mainly comprises the support that play fixed supporting role, support top is equipped with the sleeve of vertical setting, and be inserted in the sleeve striker that can pump along sleeve lining, the position of sleeve and striker is to determine in advance well according to the size of wire clamp and with the annexation of external equipment, like this, in the time of need carrying out punch operation to device clamp, only need device clamp is inserted in the support, making the terminal block of wire clamp be positioned at the striker bottom gets final product, because at this moment the pairing wire clamp terminal block of striker position promptly is the punching coordinate that sets in advance, on axially thump striker along striker from the top down with hammer then, next one eyelet clearly just can be stayed on the desired location of online folder terminal block in the striker lower end, for next step boring lays the foundation.More simplify in order to make operating procedure, make striker have the return function that goes up bullet automatically, in the striker arranged outside backing pin is arranged, the following striker outside of backing pin is set with spring, the spring lower end is pressed in the sleeve bottom inside, the spring upper end withstands on the backing pin lower end, like this, under nature, striker is just by the spring jack-up that makes progress, need not be again to support interpolation wiring folder terminal block the time manual pull-up striker, and after having knocked striker, the striker position of rebounding on also can be is automatically extracted current wire clamp and is inserted next wire clamp and continue to knock and get final product, operation is very easy, and perforating efficiency improves greatly.

As improvement, the support bottom is provided with the chopping block corresponding with striker position.

Structure one end of considering wire clamp is a terminal block, one end is the crimping handle affixed with terminal block, and terminal block is a tabular, the crimping handle is the pipe shape, so terminal block and crimping handle are in height inconsistent, when being placed into wire clamp on the support, higher crimping handle can lift an end of terminal block, terminal block just can not keep level like this, after knocking striker under such position relation, not only cause punch position inaccurate, and can cause the terminal block distortion of being bended, be unfavorable for the boring and the wiring of wire clamp.After the support bottom is provided with the chopping block corresponding with striker position, insert wire clamp again after, the wire clamp terminal block just places on the chopping block, support drop wire clip terminal block at chopping block just can keep level, like this, not only punch position is accurate behind the striker bump, and terminal block can not be out of shape.

As a kind of execution mode, the sleeve of installing on the support and the quantity of striker are at least a cover.

In order to adapt to the application of distinct device in different occasions, the sleeve of installing on the support and the quantity of striker are at least a cover, can set a plurality of wiring holes on same wire clamp terminal block like this, and is very convenient.

In sum, adopt the sample punch die tool of this structure, rational in infrastructure, easy to operate, and high efficiency, be adapted at installing or the on-the-spot use of maintenance power equipment, be particluarly suitable for the debugging occasion that task is anxious, personnel are few and use.
