Abstract
The utility model relates to a sensing spanner, which comprises a handle and a working head, wherein the working head is provided with a jaw; the upper jaw or the lower jaw of the jaw is provided with a piezoelectric plate; a metal protection plate covers at the outer side of the piezoelectric plate; and the piezoelectric plate is electrically connected with a light-emitting diode (LED) arranged on a handle. The condition of the pretightening force of a nut to be fastened can be approximately displayed by the sensing spanner in the process of fastening a bolt pair, and thereby, the pretightening force of the nut can be controlled to be within an approximate range in the fastening process.
Description
Affiliated technical field
The utility model relates to the hardware ﹠ tools field, especially, is a kind of sensing spanner that can show nut pretightning force power size.
Background technology
In the hardware ﹠ tools field, fastening or loosely open various bolts and connect and all need to use spanner, present spanner comprises handle and working head, has tiger on the described working head, after the upper jaw and the lower jaw rank of tiger is lived nut, be that rotatable handles carries out fastening or loose opening to the bolt pair, yet because each one hand strength difference in the process of clamp nut, is difficult to the grasp dynamics, do not need potent fastening bolt pair for some, if hand strength the greater takes big strength that it is fastening, this is for the less people of hand strength afterwards, and its pine is opened and just become very big trouble, therefore, in the process of fastening bolt pair, be necessary the pretightning force of nut is carried out appropriateness control, it is in the scope roughly, and this point adopts common wrench then can't realize.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of sensing spanner, and this sensing spanner can roughly demonstrate the pretightning force situation of fastened nut in the process of fastening bolt pair, thereby can in fastening process, the pretightning force of nut be controlled in the approximate range.
The technical scheme that its technical problem that solves the utility model adopts is: this sensing spanner comprises handle, working head; have tiger on the described working head; maxilla of described tiger or lower jaw are provided with a piezoelectric patches; metal coating sheet of this piezoelectric patches outer side covers, described piezoelectric patches is electrically connected with a LED who is arranged on the described handle.
As preferably, described piezoelectric patches sticks in the maxilla of described tiger.
As preferably, have a depression that matches with described piezoelectric patches on the maxilla of described tiger, described piezoelectric patches sticks in this depression, to guarantee the not slippage when stressed of described piezoelectric patches.
As preferably, described metal coating sheet sticks in described piezoelectric patches surface, and described metal coating sheet surface has coarse lines.
The beneficial effects of the utility model are: when adopting this sensing spanner fastening bolt secondary, the pretightning force of nut is passed to the piezoelectric patches on the described tiger maxilla, output voltage is to described LED behind this piezoelectric patches pressurized, then described LED is luminous, the user can judge the size of nut pretightning force by its bright intensity, thereby it is controlled in the suitable scope.
Description of drawings
Fig. 1 is the structural representation of this sensing spanner.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
In the embodiment shown in fig. 1; this sensing spanner comprises handle 1, working head 2; have tiger 21 on the described working head 2; maxilla 211 of described tiger 21 or lower jaw 212 are provided with a piezoelectric patches 3; metal coating sheet 4 of these piezoelectric patches 3 outer side covers, described piezoelectric patches 3 is electrically connected with a LED5 who is arranged on the described handle 1.
Above-mentioned sensing spanner, described piezoelectric patches 3 sticks in the maxilla 211 of described tiger 21.
Above-mentioned sensing spanner has a depression that matches with described piezoelectric patches 3 on the maxilla 211 of described tiger 21, described piezoelectric patches 3 sticks in this depression, to guarantee described piezoelectric patches 3 not slippages when stressed.
Above-mentioned sensing spanner, described metal coating sheet 4 stick in described piezoelectric patches 3 surfaces, and described metal coating sheet 4 surfaces have coarse lines.
When adopting above-mentioned sensing spanner fastening bolt secondary, the pretightning force of nut is passed to the piezoelectric patches on described tiger 21 maxillas 211, output voltage is to described LED5 behind this piezoelectric patches pressurized, then described LED5 is luminous, the user can judge the size of nut pretightning force by its bright intensity, thereby it is controlled in the suitable scope.
