Specific embodiment
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates, and X-direction indicates left and right directions in figure, and Y-direction indicates that up and down direction, Z-direction indicate front-rear direction.
As shown in Figures 1 to 7, the utility model relates to a kind of band pincers hand Improved digital multimeter, including ontology
1, external to clamp hand 2, the left pincers portion 21 being symmetrically arranged at left and right sides of external pincers 2 upper end of hand and right pincers portion 21 and the left pincers portion 21 of control
With the control switch 23 of right pincers portion 21 opening and closing, the multimeter ontology 1 is connect by conducting wire 4 with external pincers hand 2, left 21 He of pincers portion
The upper end in the upper end formation clamping part 25 in right pincers portion 21, right pincers portion 21 and left pincers portion 21 is equipped with take-up protrusion 24, passes through left and right
Mobile external pincers hand 2 can effectively spread densely arranged cable out, especially to choose deep ensconce in a pile cable and choose
A cable out.The ontology 1 is additionally provided with bumper housings 11, effectively strengthens the shatter-resistant effect of ontology 1, further increases
The safety of ontology 1.
As the specific embodiment of the utility model, the model of the external pincers hand 2 can be WH3302 or 3303, will be external
The high current of test is converted to direct current or ac voltage signal less than 2V or 200mV, directly inputs the direct current of DT152
The test gear of pressure test gear and alternating voltage.Instrument display screen is by display voltage data come the external pincers hand 2 of direct interpretation
The size of the current values of test, this design, which substantially improves multimeter maximum current, can only test the limitation of 20A, into
And improve the practicability of multimeter.
The external pincers hand 2 is additionally provided with thread hooking apparatus 3, which includes outer housing 31, fixed column 32 and telescopic mast
33, the outer housing 31 is fixedly connected in the rear surface of external pincers hand 2, which vertically extends and shell
The upper end of body 31 is equipped with opening, and fixed column 32 is protruded into from the opening and is fixedly connected with outer housing 31,33 sliding sleeve of telescopic mast
It is located in fixed column 32, the upper end of the telescopic mast 33 is installed with take-up hook 35, the center line of the fixed column 32 and described outer
The center line for connecing pincers 2 left and right directions of hand is overlapped.Take-up hook 35 is first pulled up when use, stretches out it from clamping part 25, then
Cable under test line is provoked by take-up hook 35, then telescopic mast 33 moves down, take-up hook 35 is moved to clamping part 25
Surface, and then cable under test line is driven to enter clamping part 25, clamping test, the front end of telescopic mast 33 are carried out to cable to be measured
It is symmetrically arranged with limit buckle 34, after measurement process, conducting wire is wrapped on telescopic mast 33 and test pen is withheld in limit buckle
On 34, and then test pen is fixed on telescopic mast 33.In particular it is necessary to which conducting wire 4 and test pen are taken from telescopic mast 33
Out, after entire test process, conducting wire 4 is wound along 33 outer surface of telescopic mast and is placed into the nib of test pen
In limit buckle 34, at this point, telescopic mast 33 is pushed in outer housing 31, to complete the storage to test pen and conducting wire 4.
In order to guarantee that telescopic mast 33 can slide into completely in outer housing 31, the outer housing 31, fixed column 32 and flexible
The length of column 33 is consistent, effectively stores the conducting wire 4 and test pen that are wrapped on telescopic mast 33, while preventing conducting wire 4
It is exposed outside multimeter with test pen, extend the service life of conducting wire 4 and test pen.
In order to further limit to telescopic mast 33, the front end of the outer housing 31 is equipped with threaded hole 311, the screw thread
The matching of hole 311 is equipped with threaded rod, when the preparation of telescopic mast 33 moves up, threaded post 36 is rotated in the clockwise direction, in turn
By threaded post 36 to Forward, at this point, the limit buckle 34 for being located at upper end will be far from threaded post 36, telescopic mast 33 can along fixed column 32 to
Upper sliding, telescopic mast fully slides out outside fixed column in order to prevent, when the limit buckle 34 for being located at upper end skids off outer housing 31, passes through
Threaded post 36 is rotated in the counterclockwise direction, and then threaded post 36 is dropped backward, at this point, limit buckle 34 will be to the limit for being located at lower end
Position button 34 is limited, and then is limited to telescopic mast 33.
There is a phenomenon where getting an electric shock when test man clamps cable under test line by thread hooking apparatus 3 in order to prevent, the take-up hook
35 are made of insulating materials, are specifically as follows rubber material, are played the wind for preventing take-up hook 35 from scratching cable under test line
Danger is also prevented from take-up hook 35 and generates the risk scratched to test man.
Multimeter ontology 1 is connect by conducting wire 4 by the utility model with external pincers hand 2, and it is raised that when detection first passes through group line
24 spread densely arranged cable out, then further choose cable under test line by thread hooking apparatus 3 and are moved to clamping
Portion, and then left pincers portion 21 and right pincers portion 21 are carried out to cable to be measured by clamping detection by operation-control switch 23.Therefore, whole
A detection process is directly found with hand without test man and is held cable under test, effectively avoids test man and holds electricity to be measured
Cable and the risk got an electric shock.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
