Abstract

The utility model discloses an auxiliary device for resistor measurement, which comprises a base. A rack is connected in a sliding mode inside the base; one end of the rack extends to the outer part of the left side face of the base; a worm is connected in a rotating mode inside the base; the worm and the rack are engaged; the tooth face of the worm extends to the front side face of the base; one end, outside the base, of the rack is fixedly connected with a left pen holder; and the right side face of the base is fixedly connected with a right pen holder. Two test pens can be controlled to touch the lead of a resistor by holding the base by hand, the fact that the palm keeps a state to enable the two test pens to spread for a certain angle for a long time in the case of traditional test is avoided, the palm is not likely to feel painful, and the test efficiency is improved; and in addition, the distance between the two test pens can be adjudged, test demands of resistors of different specifications can be met, and the application range of the device is improved.

Description

A kind of resistance measurement servicing unit

Technical field

The utility model relates to a kind of servicing unit, is specifically related to a kind of resistance measurement servicing unit.

Background technology

Existing resistance is the general test pen that adopts when test, utilizes the lead-in wire of manually holding test pen contact resistance, and detecting instrument can be obtained a result automatically.While utilizing test pen test, user needs one hand holding two test pens to contact with two lead-in wires of resistance respectively at every turn, in test specification during the same and a fairly large number of resistance, palm will keep making the state of two test pen fork certain angles for a long time, palm is easily ached like this, reduces the efficiency of test.

Utility model content

For solving the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, and can make test pen remain on resistance measurement servicing unit in a distance.

The utility model technical scheme adopting of dealing with problems is:

A kind of resistance measurement servicing unit, comprise pedestal, described base interior slidably connects a tooth bar, one end of described tooth bar reaches the left surface outside of pedestal, the described base interior worm screw that has been rotatably connected, described worm screw and tooth bar engagement, the flank of tooth of described worm screw reaches the leading flank of pedestal, described tooth bar is fixedly connected with and does left pen stand in one end of pedestal outside, and the right flank of described pedestal is fixedly connected with right pen stand.

As the further improvement of such scheme, the flank of tooth of described worm screw also reaches the trailing flank of pedestal.

As the further improvement of such scheme, the lower surface of described left and right pen stand is lower than the lower surface of pedestal.

The beneficial effects of the utility model: the utility model arranges worm screw and tooth bar in pedestal, the end of tooth bar and the right flank of pedestal are fixedly connected with left and right pen stand, during use, two test pens are injected respectively in the pen stand of left and right, two test pens have directly just kept certain distance, at this moment hand is held the lead-in wire that pedestal can be controlled test pen contact resistance, while not needing as traditional test, palm will not keep making the state of two test pen fork certain angles for a long time, palm is not prone to and aches, and improves testing efficiency.Resistance to different size, regulates worm screw, can make tooth bar stretch out the part of pedestal elongated or shorten, thereby regulates the spacing of two test pens, until meet test needs, improves the accommodation of this device.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Fig. 1 is cross-sectional schematic of the present utility model;

Fig. 2 is schematic top plan view of the present utility model.

Embodiment

See figures.1.and.2, a kind of resistance measurement servicing unit, comprise pedestal 1, described pedestal 1 inside slidably connects a tooth bar 2, and it is outside that one end of described tooth bar 2 reaches the left surface of pedestal 1, the described pedestal 1 inside worm screw 3 that has been rotatably connected, described worm screw 3 and tooth bar 2 engagements, the flank of tooth of described worm screw 3 reaches the leading flank of pedestal 1, and described tooth bar 2 is fixedly connected with and does left pen stand 4 in one end of pedestal 1 outside, and the right flank of described pedestal 1 is fixedly connected with right pen stand 5.

As further preferred embodiment, the flank of tooth of described worm screw 3 also reaches the trailing flank of pedestal 1.All there is the flank of tooth of worm screw 3 the front and back sides outside of pedestal 1, is convenient to point from different directions stir worm screw 3.

As further preferred embodiment, the lower surface of described left and right pen stand 4,5 is lower than the lower surface of pedestal 1.When test pen injects left and right pen stand 4,5, the nib of test pen can, lower than the lower surface of pedestal 1, be convenient to the lead-in wire that nib removes contact resistance.

The utility model in use, two test pens 6 are injected respectively in left and right pen stand 4,5, hold pedestal 1, finger is stirred the flank of tooth that is exposed to pedestal 1 outside of worm screw 3, make tooth bar 2 stretch or contract, adjust between two test pens 6 to suitable distance, hold pedestal 1 and allow two lead-in wires of difference nib contact resistance of two test pens 6.

The above is preferably embodiment of the utility model, and it does not form the restriction to the utility model protection domain, so long as realize the purpose of this utility model with essentially identical means, all should belong to protection domain of the present utility model.
