The panel parallel of card 3, the L-type of the handle 27 is outside, at this point, the spring 23 is in free state, the four of outer core 22
The lateral square groove that square body is constituted with the pedestal 1 matches, front end cylinder and the composition of the pedestal 1 of the inner core 26
Horizontal circular groove matches installation.Under such state, the handle 27 of the spanner 2 is stretched out, the spring 23 is in pressure
Contracting state, outer core 22 and the inner core 26 are moved out with the handle 27, wherein the cubic cylinder of outer core 22 can
The lateral square groove of the composition of the pedestal 1 is pulled out, the inner core 26 also pulls out the lateral circular groove of the composition of pedestal 1, hides in the ball
In the built-in straight hole of barred body 21, schematic diagram when spanner as shown in FIG. 11 and 12 stretches rotation is formed.At this point, the spanner
2 handle 27 can rotate clockwise 90 degree to vertical direction with the sliding groove that the bat body 21 is constituted along the pedestal 1,
Meanwhile the handle 27 of the spanner 2 can with the bat body 21 in spherical slot clockwise from turn 90 degrees, by the handle
27 L-type be adjusted to top, when the spring 23 in a free state, 26 front end of the tetragonal body of outer core 22 and the inner core
Column can be inserted into respectively in the square groove and circular groove of 1 vertical direction of the pedestal, form such as Fig. 2, Fig. 9, spanner shown in Fig. 10
The schematic diagram at place and vertical position.Before the median plane and the second endoporus of the L-shaped handle 27, the first endoporus and outer core 22
It is same plane to hold the median plane of square body, ensures the use state of the handle 27 when lateral position and vertical position.
To sum up, drawing-aid device of the invention is by stretching, rotation and rotation, makes the drawing-aid device both and can control and communication equipment
The assembly of cabinet, and the position of handle portion can be controlled, so that handle portion is in horizontal and vertical direction according to behaviour in service,
The device terminal that can effectively avoid board front panel is arranged such occupies space, does not influence the device layout of board front panel.
The drawing-aid device is simple and reliable for structure, can farthest utilize structure space, smaller to space structure requirement, is conducive to highly dense
Spend the design of product.
