Description
Technical field
The utility model relates to one kind screwdrivers used in the assembling of pressure transmitter amplifier block, specifically
It is a kind of with prevent skid and guide-localization function Speical screwdriver.
Background technique
In prior art, the Jin Gu ﹑ of screw is installed, generally according to the classification of screw, in: Kai Cao ﹑ Shi Zi Cao ﹑
The Yi Zi ﹑ Shi Zi ﹑ allen driver of hexagonal etc., selection standard carries out tightening operation.But for the special of amplifier block
Screw is provided with the internal thread hole of M3 because of the particularity of its structure at screw straight groove, spiro rod length 25mm, diameter 2mm, whole
Body is slim-lined construction.When therefore selecting common straight screwdriver that fastening is installed, it may occur that location difficulty, screw when applying torsion
Sliding teeth, and the problems such as installation effectiveness is low.
Summary of the invention
The utility model is in view of the above-mentioned problems, provide a kind of with the full dog point socket set for preventing from skidding with guide-localization function
Knife, the screwdriver can the less screw outlet screw in rundown process skid, the problem of guide-localization difficulty, improve work and imitate
Rate, convenient for operation, installation.
According to the technical solution of the utility model includes: it is a kind of with prevent skid and guide-localization function Speical screwdriver,
It is characterized by comprising screwdriver ontology, screwdriver ontology includes central axis and is set to central axis axial end face and radially
Arc plate is respectively set in the word plate extended, word plate elongatedness direction both ends, and the center setting of a word plate is perpendicular
The cylindrical body directly extended downwardly, the length of the cylindrical body are greater than the axial length of arc plate.
The lower end of cylindrical body shape spherical in shape as a further improvement of the utility model,.
The outer surface of the arc plate corresponds to the radius and central axis of circular arc as a further improvement of the utility model,
Radius is consistent.
The word plate is consistent with the axial extension of arc plate as a further improvement of the utility model,.
The utility model has the technical effect that the utility model product due to constituting anti-skid structure, work using arc plate
Screw ensure that defined torque value without slipping phenomenon when making, and screw locking is more reliable；The structure is realized reliable by cylindrical body
Positioning, steering capability is good, efficiently solve screwdriver be difficult to screw position, screwdriver damage other parts the problem of；
The structure is installed simply in assembling process, time saving and energy saving, improves assembly efficiency.

Specific embodiment
Specific embodiment of the present utility model is further described with reference to the accompanying drawing.
Fig. 1, in 2, including screwdriver ontology 10, cylindrical body 11, a word plate 12, arc plate 13, central axis 14, amplifier
Component 20, screw 21, gearbox case 30 etc..
As shown in Figure 1, 2, the utility model is a kind of with the Speical screwdriver for preventing from skidding with guide-localization function, packet
Screwdriver ontology 10 is included, screwdriver ontology 10 includes central axis 14 and is set to 14 axial end face of central axis and radially extends
One word plate 12, at work, the word fluting position cooperation of a word plate 12 and screw 21 can effectively transmit torsion, institute
It states 12 elongatedness direction both ends of a word plate and arc plate 13 is respectively set, effective anti-skidding, a word plate may be implemented in arc plate 13
The cylindrical body 11 extended straight down is arranged in 12 center, realizes positioning and guiding, the length of the cylindrical body 11 by cylindrical body 11
Degree is greater than the axial length of arc plate 13.Cylindrical body 11, a word plate 12, arc plate 13 are connected by way of electro-discharge machining
It is whole.
The lower end of cylindrical body 11 shape spherical in shape can quickly and smoothly be inserted into 21, screw using spherical structure outstanding
In the internal thread hole in portion.The diameter of cylindrical body 11 and the threaded hole of screw 21 are transition fit, ensure that screwdriver and screw 21
Reliable location, the spherical structure of cylindrical body 11 can protect internal screw thread thread, prevent screwdriver ontology 10 from damaging thread.
The radius that the outer surface of arc plate 13 corresponds to circular arc is consistent with the radius of central axis 14.
One word plate 12 is consistent with the axial extension of arc plate 13.When work, the inner circle and screw 21 of arc plate 13
The cooperation of outer circle position, the fit tolerance of the internal diameter of arc plate 13 and 21 head outer circle of screw is transition fit, is twisting solid process
In with screw 21 be fitted close, prevent 10 exfoliation and slipping of screwdriver ontology.
The course of work of the utility model is as follows: in use, amplifier block 20 is fixed on outside speed changer by screw 21
On shell 30；Using 11 positioning and guiding of cylindrical body outstanding among driver bit, middle part laterally projecting a word plate 12 and screw
Flat recess cooperation, rotation transmitting torsion；It is positioned, is prevented using inner circle and screw head the outer circle cooperation of screwdriver arc plate 13
It skids；During screwdriver rotation, transmitting torsion is reliable and stable, and screw is without skidding stuck phenomenon.
