Specific embodiment
By way of example and in conjunction with the accompanying drawings, the invention will be further described:
In conjunction with shown in Fig. 1-3, a kind of electronic connection bolt, mainly by the first fixes sleeve 1, the second fixes sleeve 2, electricity
Machine 3, connecting shaft 4 and connecting screw 5 form.
Internal screw thread is provided in the first fixes sleeve 1, the second fixes sleeve 2, internal screw thread is outer with connecting screw 5
Screw thread matching.
Motor 3 is fixedly mounted in the first fixes sleeve 1 and at back-end location.The front end of connecting shaft 4 is provided with spline
Shape protrusion 4a, the bar portion of connecting shaft 4 are round bar.The strip groove 5a that cross section is spline-like, strip groove are provided in connecting screw 5
The length of 5a is determined according to the stroke that connecting screw 5 moves axially.Flower key shaped projection 4a, which is protruded into, realizes connecting shaft 4 in strip groove 5a
It being connect with the spline of connecting screw 5, torque transmitting is realized in spline connection, while flower key shaped projection can move in bar shaped, so that
Connecting screw can opposite connecting shaft axial movement.The rear end of connecting shaft 4 is connected with motor 3.
(the shape as shown in Figure 2 after the first fixes sleeve 1 is with the fitting of the end of the second fixes sleeve 2 and axis is overlapped
State), motor 3 is drivingly connected axis 4 and rotates, and while connecting shaft 4 drives connecting screw 5 to rotate synchronously, connecting screw 5 is moved axially
